Jeremiah 10:1-4 KJV
Is Jeremiah talking about a Yule Tree here?

It would appear that this is not the case, when the entire passage is read according to the webpage article Jeremiah 10 and the "Pagan" Christmas Tree (Bucher, 2000), the next verses detail that
and importantly, according to the article Jeremiah 10 and Christmas Trees it is concluded that Jeremiah is not condemning Christmas trees (a practice started in Europe in the 16th century AD), but is condemning idolatry.
share|improve this answer
Jeremiah is operating in the capacity of The Lord's mouthpiece to the house of Israel. In 10:2 The Lord sends a warning to them saying: "Learn not the ways of the (ungodly)nations." By learning their ways the house of Israel could start practicing them. In 10:3 He states that their customs or ways are vanity (false). The Lord then gives them an example that they were probably familiar with, which was the decorating of the tree. Once the tree was decorated they would worship it as if it were a God. Deuteronomy 5:7-10 explains how The Lord feels about this practice, and the consequences that will incur.

No. The next sentence goes on to talk about how they will not walk on their own. Yule trees do not receive such anthropomorphic language. Passage 11 clarifies that this is talking about carving/fashioning gods (idols), not a pagan tree custom.
Also, while some do argue for an early veneration of evergreen trees that may be precursor to Yule tree in later Germany, this is not seen in Semitic cultures of this period making this question an almost laughable anachronism.

It may not have been seen in Semitic cultures, but the practice would have been seen from the Romans. The passage warns against "Learn not the way of the nations", obviously we're not talking about just Semitic cultures here. – The Freemason Dec 30 '13 at 3:58
So you presume the ancient Jews had contact with the Romans in the 6th century BC? I have something to sell you :) – user1985 Jan 2 at 0:14
I may be off by 600 years or so. Maybe The Roman link isn't the best. But my point is that the text suggests something outside of the Semitic cultures. – The Freemason Jan 2 at 1:11
I think the text suggests a practice outside of Jewish culture, but to say more than that is an assumption. Who's to say they even had much contact with non-Semitic cultures at that time? I don't know answer I just ask – user1985 Jan 3 at 21:43

The Amazon milk frog is found in tropical rain forests in northern South America. It lives its entire life in the forest canopy and rarely, if ever, descends to the ground. This species is considered large for a tree frog and adults usually range in size from 2.5 to 4 inches. Males are smaller than females.
The coloration of an adult Amazon milk frog can range from dark brown with light grey or white banding, to light grey with dark brown banding. Juveniles are banded black and white. The eyes are golden in color with a black Maltese cross centered on the pupil. There is a vocal sac on each side of the head.
Look for the Amazon milk frog in green tree boa exhibit in the River Scout gallery.


- With college just a year or two away, why do schools hold seniors and juniors in the same type of work schedule they had when they were in middle school?
 - Knowing that all students learn differently, why do we hold them all to the same structure?
 - With technology and the Internet changing how we work, why do schools retain a structure they had a century ago?
 - With new jobs emerging all the time, and with most people changing careers and jobs much more frequently than ever before, how do we know the traditional school model prepares our graduates for their future?
 - Read about the rationale for why we developed the Blended Classes Model
 At Shattuck-St. Mary's, ScholarShift =
 + self-management
 + 21st century skills
 + passion development and exploration
 + flexibility
 + breaking out of the old schedule
 + customization
 + independence/initiative
 + sustained energy & engagement
 + projects/experiences beyond the classroom
 + "true college prep"
What is ScholarShift®?
 - Beginning with the SSM Class of 2018, our educational approach for the 11th and 12th grades will grow to include, in addition to the excellent college preparatory academic program we have long offered, a series of educational experiences comprised of blended classes, a parallel curriculum of learning modules, and a year-long self-designed educational experience. We are calling this series of experiences ScholarShift.
 - Juniors will choose from a broad catalog of modules, many of which have been proposed by the students themselves. The modules focus on everything from financial literacy to writing poetry, from film making to gender roles in popular media. Students will have the opportunity to study botany in our own backyard, record and edit podcasts in our weCreate Center, and grapple with the complex issues facing our local and national communities today. After completing this foundational year, seniors will spend their final year at SSM engaged in internships, developing significant research projects, or designing other year-long experiences that explore their passions and expand their skills and talents.
 - 11th and 12th grade academic classes will be offered in a blended class model. This model opens up the weekly schedule so that students can engage in the opportunities ScholarShift provides alongside their traditional, classroom-based academic program. It also requires students to hone their time management skills and prepares them for the college model in which seeking extra help from professors requires planning and initiative and each day is not predetermined hour by hour.
 - To meet our academic graduation requirements, our students will complete their academic coursework plus the three-year ScholarShift series of experiences. Completion of these new requirements will be reflected on student transcripts along with the full array of rigorous college preparatory courses currently offered in our curriculum.

1. The effects of adrenalectomy on the adenylate cyclase—adenosine 3′:5′-cyclic monophosphate (cyclic AMP) system of rat renal medulla were examined to evaluate the mechanism of the impaired water diuresis in glucocorticoid deficiency.
2. Concentrations of cyclic AMP in medullary tubules from adrenalectomized rats were significantly higher than in the tubules from control animals both in the presence and absence of antidiuretic hormone.
3. This abnormality was corrected by the treatment in vivo of the adrenalectomized rats with dexamethasone, but addition of this drug to the incubation medium did not abolish the differences in cyclic AMP between tubules from adrenalectomized and normal rats.
4. The activity of adenylate cyclase or cyclic AMP phosphodiesterase in vitro was not affected by adrenalectomy.
5. In glucocorticoid deficiency, the concentration of cyclic AMP in medullary tubules is increased both with and without antidiuretic hormone. This abnormality may render medullary tubules more permeable to water and may underlie the impaired water diuresis in glucocorticoid deficiency.

Websites are conversations
"Why are you purple?" I asked.
"What's that?"
"Websites are conversations."
I was in a hurry and didn't have time to talk then, and so I invited the owl over to my café. He arrived the following Tuesday. I brought a couple of tall lattes over to our table and he explained what he meant.
To be concise, as I know your time is limited, the owl told me that:
 1. The key to a successful website is intimacy.
 2. The most successful websites do more listening than they do talking.
 3. Non verbal communication is often more important than what is explicitly said.
I know this all sounds a little odd but a blog has to start somewhere.

A NativeScript Font Icon Converter
Getting set up to use Icon Fonts in a NativeScript app is fairly straight-forward. NativeScript documentation covers it, and Nathanael Anderson has a tutorial covering things in more depth. However, there's one annoyance I have with using them in NativeScript and this post will cover that and one way to resolve it.
The Annoyance
Once you're set up to use icon fonts, you'll typically have a CSS rule defined to set the font-family when a certain class is used:
.fa {
 font-family: FontAwesome;
But, as you can see in the above referenced getting started docs/tutorial, CSS is not what sets the content as it would be if we were using HTML and Icon Fonts. We have to find the unicode and set the text property of our element to use that:
So you must either memorize the unicode for your font icons or be resigned to looking them up every time.
One solution
NativeScript has a feature baked into it called Converters - essentially functions you can pipe an input to and have it converted to a different output without changing the source (i.e. a property on a model). You can also have application-wide converters by adding them to your application's resources, which is what we'll be using to make it easier to use our icon fonts!.
Create our Converter Function
The first thing we'll want to do is to create the function that will be our converter. Let's create a new directory: app/utils/ and create a new TypeScript file within named fontIconConverter.ts. This converter is actually really simple - it just has a hash map of all the icons we want to use and their unicode value, then provides a function for converting strings, or parts of strings, to the appropriate unicode value. Notice below that we're also handling cases where an icon may be passed in within a string of text.
// app/utils/fontIconConverter.ts
const fontToUnicode = {
 //I recommend using the full css class name of the icon (i.e. 'fa-bluetooth')
 // instead of shortening (i.e. just 'bluetooth') in case you need to use the
 // text along side an icon
 'fa-bluetooth': '\uf293',
 'fa-hashtag': '\uf292',
 'fa-usb': '\uf287'
function valueToFontUnicode(value: string): string {
 //if the value isn't a key in our hash map, just return the value as it is
 return fontToUnicode[value] || value;
export default function fontIconConverter(value: string): string {
 //check for spaces so we can handle things like "fa-bluetooth some text here"
 if (/\s/.test(value)) {
 return value.split(/\s/).map(t => valueToFontUnicode(t)).join(' ');
 } else {
 return valueToFontUnicode(value);
Make the converter accessible application-wide
Now that we've defined a converter function, we just need to add it to our application resources to make it available application-wide. Simply navigate to your app/app.ts file, and make the following additions:
import fontIconConverter from './utils/fontIconConverter';
application.resources['fontIconConverter'] = fontIconConverter;
Use the converter in your view
Now that we've added the converter to our application resources, we can use it in any view like this:
Is it still clunky/ugly? Yep. But, I find it easier to remember the actual names of the icons over their unicode values. So, in an app where a lot of different icons are being used, this may just be helpful. If you're only using one or two icons then maybe it wouldn't be worth it - you'd have to decide :)
Quick Caveat
Any time that you are using the binding syntax {{... }} your view must have a binding context or it won't interpolate. Even if all you're doing is taking a static string, such as is the case with the font icon converter, and running it through a converter. If needed, you can just set the binding context to an empty object and that works, but kinda feels hacky to me.
It's certainly not a perfect/elegant solution, but as far as I can find it's either typing in the unicode directly to the label or some converter like this when it comes to using font icons. If you know of a better approach, feel free to share in the comments!

The X-ray diffraction of methanol molecules confined in carbon micropores having different pore widths (micropore widths, 0.7 and 1.1 nm) was measured at 303 K and the structural results were compared with those of ethanol. The methanol molecules confined in micropores of 0.7 nm have a more solid-like ordered structure than in 1.1 nm. The nearest-neighbor peak of the electron radial distribution function of confined methanol did not shift from that of bulk methanol, but the amplitude was much greater than that of bulk methanol. These results were different from those of confined ethanol. Methanol molecules confined in carbon micropores have a rigid organized structure even at 303 K. However, no remarkable orientation effect, as in confined ethanol, was observed.

The Evolution and Excellence of Swiss Turning
Swiss turning, a unique and specialized process in the world of machining, boasts a rich history and technological advancements that make it a go-to for high precision turned parts. Let's take a deeper dive into this remarkable technique and understand why it is so widely revered.
A Journey Through Time
Swiss turning traces its roots back to the 19th century in Switzerland. At the time, there was a growing demand for miniature screws to support the thriving watch industry. To cater to this demand, the Swiss Screw machine, known by various names such as the Swiss Lathe, Swiss Automatic, and Sliding Headstock Lathe, was developed. This ingenious invention far surpassed the precision of the traditional "fixed headstock" lathes, particularly for minuscule parts. Read More

sd_bus_slot_set_floating, sd_bus_slot_get_floating — Control whether a bus slot object is "floating"
sd_bus_slot_set_floating() controls whether the specified bus slot object
slot shall be "floating" or not. A floating bus slot object's lifetime is bound to the
lifetime of the bus object it is associated with, meaning that it remains allocated as long as the bus object
itself and is freed automatically when the bus object is freed. Regular (i.e. non-floating) bus slot objects keep
the bus referenced, hence the bus object remains allocated at least as long as there remains at least one
referenced bus slot object around. The floating state hence controls the direction of referencing between the bus
object and the bus slot objects: if floating the bus pins the bus slot, and otherwise the bus slot pins the bus
sd_bus_slot_set_floating() to switch between both modes: if the
b parameter is zero, the slot object is considered floating, otherwise it is made a regular
(non-floating) slot object.
Bus slot objects may be allocated with calls such as
sd_bus_add_match(3). If the
slot of these functions is nonNULL the slot object will be of the
regular kind (i.e. non-floating), otherwise it will be created floating. With
sd_bus_slot_set_floating() a bus slot object allocated as regular can be converted into a
floating object and back. This is particularly useful for creating a bus slot object, then changing parameters of
it, and then turning it into a floating object, whose lifecycle is managed by the bus object.
sd_bus_slot_get_floating() returns the current floating state of the specified bus slot
object. It returns negative on error, zero if the bus slot object is a regular (non-floating) object and positive
On success, these functions return 0 or a positive integer. On failure, they return a negative errno-style error code.
Returned errors may indicate the following problems:
These APIs are implemented as a shared
library, which can be compiled and linked to with the


A Grunt rule consists of multiple settings that help you format your objects. However, you don't always want to change all the settings that are available within a rule. This is where setting modes will help you out.
To the right of each setting in the Rule Edit dialog, you'll see a colored square that controls the setting mode. Each setting mode is represented by a different color, and each mode behaves differently.
What does the setting modes mean?
We will use the Character style rule to exemplify how the setting modes work. There are three types of setting modes: Inherit, Automatic or Manual.
 - Right-click on the colored square to change between the available modes.
 - Left-click to toggle between the available modes. Left-clicking more times will continue to toggle you to the next available mode.
 1. Manual values are represented by blue squares. Manual values let you choose a specific setting for the specific rule. In this example, you can choose the color you prefer for your font.
 2. Automatic values are represented by purple squares. These are also settings that are specifically set in the rule, and their formatting will be applied to your objects. This is the same behavior as for manual values, however, with automatic values, the concrete value that is used is automatically selected by Grunt. For example: If the color setting is set to automatic, that means that Grunt will choose a color for the text, based on the color of the background.
 3. Inherited values are represented by orange squares. This is normally the default mode. The inherited values are not set specifically in the rule. Instead, the value is inherited from the preceding parts of the rule stack. If there are no preceding rules affecting the specific settings, like in this case: the font color, Grunt will apply its default settings.

UCI Libraries Projected Resource Requirements through 2015–2016
The UCI Libraries Projected Resource Requirements through 2015–2016 presents the resources needed to meet the above goals and to fulfill our assessment of the demands of new programs and campus growth. The quality of the Libraries will play an important role in attracting and retaining outstanding faculty and students, and substantial investment will be needed to ensure that library services and resources are in place to support their success.
These projections are conservative and represent our assessment of what is needed to provide a quality library that can sustain UC Irvine's academic goals. Benchmark comparisons to other leading universities substantiate these assessments.
Structure, Staffing, and Services
Currently, UCI Libraries consist of four divisions with the following librarian and staff FTE:
- Collections: 18
- Public Services: 87
- Technical Services: 70
- Administrative Services: 20
- Library administration: 8
- Total librarian and support staff FTE: 203
- The Libraries employ approximately 240 students for 70 FTEs.
In the future, increased investment in the Libraries will be necessary to hire the expert staff and build the collections that will be required to support the growing number of students and faculty, and the development of new academic programs. We will actively engage with the campus to plan for the development of library services and resources to support new academic programs and evolving needs, and we will continue to recruit high quality professionals with the skills to support the changing needs of the university.

10.1 The Schwarzschild Solution
This section will present a simple derivation for the Schwarzschild solution of general relativity and then derive perihelion procession.
In pretty much any general relativity text you will find a Schwarzschild solution derivation. Just to be different and do it my own way, this will be a Kerr-Schild coordinate derivation of the Schwarzschild solution that we will then transform to Schwarzschild coordinates resulting in:
Kerr-Schild coordinates are such that the coordinate speed of inward radial moving light is c. I am also looking for a spherically symmetric static vacuum solution. In other words I am looking for an exact vacuum solution to Einstein's field equations that will take the form:
Einstein's field equations are so nonlinear that when seeking an exact solution with a trial metric you'll want to start by finding the Einstein tensor for the simplest case of the trial first as you may end up with thousands of terms in the resulting Einstein tensor making it essentially impossible to solve, so for example we will actually first seek an exact vacuum solution in the form of
and should one not exist, then we would resort to finding the Einstein tensor for 10.1.2a and seek an exact vacuum solution from that.
112 Chapter 10 The Schwarzschild Black Hole
The Einstein tensor from 10.1.2b is
so all we have to do is find the solution for f + rdf/dr = 0 and we have an exact vacuum solution. The f that is the solution to this simple to solve first order linear seperable differential equation is f = r0/r where r0 is a constant so we have the Kerr-Schild coordinate expression for the Schwarzschild solution as:
Next one would calculate the Reimann tensor and make sure that it is not zero ensuring that the vacuum solution found isn't a mere frame transformation of the metric of special relativity, and doing so one finds there are many nonzero elements for the Riemann tensor for this vacuum solution. According to the Birkoff theorem any spherically symetric exact vacuum solution is nothing more than a frame transformation of the Schwarzschild solution, so we've found the solution. The transformation that takes this to Schwarzschild coordinates is
10.1 The Schwarzschild Solution 113
And defining a constant M by
yields 10.1.1 as the exact vacuum solution to Einstein's field equations called the Schwarzschild solution.
An exact calculation of the radial case of geodesic motion a test particle undergoes in terms of M for this spacetime yeilds
where is the proper time for the test particle, and so we see that this constant M in this exact vacuum solution for Einstein's field equations is what we think of as the active "gravitational mass".
For a black hole r0 is called the Schwarzschild radius. The Schwarzschild solution of general relativity is the solution for the case of a non-rotating uncharged black hole. The Schwartzschild radius describes a mathematical surface at which there is also a coordinate singularity for this kind of black hole.
10.1 The Schwarzschild Solution 115
The coordinate singularity for general relativity is a place where infinities appear in our equations due to our choice of coordinates such as the
term has at r = r0 , but locally no physical quantities are infinite. In general relativity this surface is called an event horizon. Most generally an event horizon is any surface at which the coordinate speed of light vanishes.
Now lets derive perihelion procession.
The Schwarzschild solution is independent of both ct and yielding two Killing four-vectors
The first gives us the following conserved quantity for geodesic motion called the energy parameter for which we define by
The second killing four-vector results in another conserved quantity for geodesic motion called the angular momentum parameter,
Inserting these into the Schwarzschild solution itself and dividing through by results in
Orient the equatorial plane to match the orbit so .
With a little algebra we wind up with equations of motion that look very Newtonian
the difference being that the relativistic expression corresponding to conservation of energy here has a term that looks like a 1/r3 potential, or a 1/r4 force. Using the second in the first
Changing variables to u = 1/r
Differentiate with respect to u and chain rule
Its a strait forward back check to verify neglecting terms in the check above first order in (GM/c2) the following expression satisfies that differential equation
And so works as an approximate solution for a weak field.
The perihelions now occur at
If the period of the orbit is T, then the total change in angle for the location of perihelion over time is then
or in terms of the length of the semi-major axis a:
The complete exact equations of geodesic motion for a test mass in a Schwarzschild spacetime are
where is a constant of the motion and is equal to the of special relativity at , and is a constant of the motion and can be thought of as the angular momentum of the test particle in orbit divided by its mass.
Verify that far from the hole, the Schwarzschild solution obeys Eqn. 9.2.4 to order 1/r2.
Look up recent solar system data and use equation 10.1.20 to find for the mercury's procession after 100 of Earth's years. (Note - It is actually 575", but 534" are accounted for by the effect of other planets.)
116 Chapter 10 The Schwarzschild Black Hole
10.2 Hovering over a Schwarzschild Black Hole
In this section we derive the equation for the amount of force felt by an object held stationary over a Schwarzschild black hole for general relativity.
and then mention why we see from this that the assumption that we could hold it stationary underneath the event horizon was false.
Start four-acceleration Eqn. 5.3.1
Which simplifies to Eqn.10.2.1
This is the amount of force felt by the object hovering over the hole for general relativity. We should note that it
10.2 Hovering over a Schwarzschild Black Hole 117
becomes infinite at the event horizon and imaginary underneath and therefor the very assumption that an object underneath the event horizon of a Schwarzschild black hole could be held still was false.
Consider a cable lowering an observer of m down to the event horizon of a black hole. The work required to do this turns out to be mc2 and so the reaction force that the hovering cable wench feels must always be finite, right down to the event horizon. However, the tension in the bottom part of the cable attached to the lowered observer diverges and so it always snaps just prior to reaching it. Show that the tension in the bottom end of the cable near the event horizon a height h above it is given by
Use Eqn. 10.2.1 to find the weight felt by a 75 kg observer standing 100m over the event horizon of a 3 solar mass black hole.
118 Chapter 10 The Schwarzschild Black Hole
10.3 Exact Spacetime Inside Static Spherically Symmetric Matter
By a static spherically symmetric matter distribution I will mean matter for which coordinates can be found such that the line element for the interior solution can be written as
where f, g, and g00 are functions of r. In derivations of the Schwarzschild solution it is common to choose Schwarzschild coordinates such that g is absorbed into the definition of r leaving only the functions f and g00 to find. It is more convenient in this case to instead choose isotropic coordinates. Since the f in front of the dr2 term and the g in front of the terms are functions of the coordinate r, one is free to choose a radial coordinate such that the line element becomes
where hn is some function of the new radial coordinate r. Exactly working out the Einstein tensor for this line element and referring to Einstein's field equations one finds that the time-time element of the stress-energy tensor T 00 that exactly corresponds to this line element which merely required static spherical symmetry expressed in isotropic coordinates is
One might immediately recognize the (dh/dr)2 term as associated with an electric field's energy density and h as proportional to its electric potential. Lets consider however, that we are interested in uncharged matter first. The choice of n=4 will yield a zero energy density wherever the Laplacian of h is zero which means that choosing n=4 would correspond to h having an interpretation of being proportional to the Newtonian gravitational potential yielding vacuum where the Laplacian of h or the Laplacian of the proportional gravitational potential is zero. So for the case of uncharged matter it is natural to choose n to be 4. In that case the line element becomes
And the time-time element of the stress-energy tensor that corresponds exactly to that is
At this point we can define a new function in terms of h that will correspond to the Newtonian gravitational potential as
In doing so the line element is written
and the time-time element of the stress-energy tensor exactly corresponding to this is
we see that the time-time element of the stress-energy tensor can be written
In places of weak gravitation where we see now that the energy density corresponds to the Newtonian energy density at that same place where the spatial elements of the line element correspond to Euclidean coordinates. An observer for which these coordinates are appropriate, for which they are a mere spherical coordinate transformation of that of special relativity nearby him finds that nearby him the energy density observed corresponds to that of Newton where is the matter's Newtonian gravitational potential.
Next I will define a function in terms

About Bitmark
Charter is being developed by Bitmark, who has been working on empowering people online since 2014. Bitmark's best-known product, the Bitmark Protocol, allows people to autonomously govern their digital properties and gives them the agency to use them as they see fit. Charter is a new initiative for Bitmark, built on the Bitmark Protocol and the company's core principles. It is a response to the 2016 attacks on democracy.
It's been a stressful last few months for everyone at Bitmark, and I am sure you or many people you know have been struggling as well. After the last newsletter, we had expected to launch Spring, our app to help people get their Facebook data, understand it, and eventually use it under their own control.
As we saw the suffering caused by COVID-19, however, we felt an obligation to use our resources to help.
You may already know that through our past efforts in healthcare, our team has learned from patients around the world who suffered greatly from data breaches or were denied access to their health data. Since then, these insights have led our work to put individuals in full control of their data. Our past projects include helping Pfizer match patients to clinical trials while preserving privacy, UC Berkeley safely source health data from underrepresented populations for public health studies, and H2 form the world's first data trust to cure diabetes.
As we spoke with people about the impact of COVID-19, we learned that people understood what was going on at a greater regional level, but did not know what this meant specifically for them. Was anyone in their neighborhood affected? Were certain areas nearby less exposed to the virus than others? Where would it be safe to take family for a walk?
In response, we are building Autonomy to answer these questions through local neighborhood health forecasts. These forecasts are presented through a numerical score that encapsulates the relative danger of a neighborhood. Autonomy learns from data provided by you, those near you, and verified public sources – every so often, you'll receive a notification when your neighborhood's health forecast has changed and requests to share information about how you are doing. Your privacy is always protected.
While Autonomy was created to help measure the spread of COVID-19, our vision is for much wider applicability by enabling mass participation in public health. In the future it might detect cancer clusters or assess how common the cold is in your local community. It might help to evaluate the precise effects of pollution or allergens on our health. It can be an early warning system, a danger assessor, and an analytic research tool. It can help us all to get better. Together.
We expect to launch Autonomy next week in Taiwan, and we are talking with partners throughout the US and Europe to help us support local communities – Autonomy needs local, verified data along with advocates to get the word out. If you can help, please reach out to me. As with the Bitmark protocol, Autonomy is open-source software and available for anyone to use, validate, or modify for themselves.

Happy new decade! I hope you're not looking for the unsubscribe button already – we have not sent a newsletter in a very long time. There are a number of reasons for that, but I've been mainly wondering about what you wanted when you originally signed up.
No one likes getting junk in their email and I certainly do not want to waste your time.
Next week, we're going to release our new app Spring to the Apple iOS and Android app stores. I will send you a separate email about that soon. I'm very excited to tell you about it.
Here's what I'd like to do moving forward, however. Each month, I can give you an update on how Bitmark is doing:
 - Any recent media coverage
 - Past and upcoming events
 - News on current projects, partners, and products
 - Interesting articles that we've been sharing internally
For example, a few months ago, we ran an "Artist-to-Peer" (A2P) experiment with renown artist Casey Reas that was covered by WIRED and also Artnome. We see computational art as the beachhead into the larger art market. How, and Why, Artists Exchange Work (NYT article) and Fluxus show how this method has worked in the past. Reas, along with three other curators, selected 75 of the top artists working with digital formats. Each artist made an original digital artwork that was registered to the Bitmark system. From that artwork, 11 tradable editions were generated, each with its own unique provenance. The artists then had one week to build a personal art collection by trading their editions with one another.

Sean also spoke on the UFO podcast (100K followers), was interviewed by DigiTimes for our work in health, presented Spring at UC Berkeley, was a panelist at the 4th Taiwan Blockchain Summit 2019, and spoke at RadicalXChange Berlin about "Data Dignity and Digital Property Rights" and "Data Dignified Healthcare" with Robert Miller (ConsenSys), Nicolas Della Penna (MIT), Anish Mohammed (SRH Berlin). Bitmark represented Taiwan at the Singapore FinTech Festival, which hosted 60,000 people from 130 countries.

A Philosophy of Blockchain: Is Secrecy a Danger?
A Philosophy of Blockchain: Is Secrecy a Danger?
Proof of stake could endanger the equality of the blockchain and hidden centralizations could endanger its trustlessness. However, there's another innovation that may endanger both…
written by Shannon Appelcline
Upon inventing Bitcoin, Satoshi Nakamoto created an open ledger that anyone could write to as long as they followed the consensus rules. This design revealed two crucial elements of blockchain design. First, it declared the equality of the blockchain: anyone could see anything on the blockchain thanks to its permissionless design; and anyone could add any valid transaction to the blockchain thanks to its censorship resistance. Second, it demonstrated the trustlessness of the blockchain: anyone could verify that both the blocks and their transactions were validly constructed.
But the founding principles of a community are constantly endangered as it grows and evolves. As we've written in past philosophy articles, we feel that proof of stake could endanger the equality of the blockchain and that hidden centralizations could endanger its trustlessness. However, there's another innovation that may endanger both: secrecy.
A Confidential Possibility
There has been a bit of secrecy in Bitcoin from the start, as Satoshi Nakamoto states in the original paper: "The necessity to announce all transactions publicly precludes [traditional privacy, which limits information about an exchange to the parties involved and a trusted third party], but privacy can still be maintained by breaking the flow of information in another place: by keeping public keys anonymous."
from Satoshi Nakamoto's paper. _URL_
However, the blockchain is not truly anonymous. At best, it's pseudonymous and even that's quite fragile. It depends on strict key hygiene, where everyone constantly creates new keys, and even then there's the danger of correlation if someone can detect clusters of addresses and connect any of them to a real-world identity.
The quest for privacy beyond Nakamoto's pseudonymity has loomed large as Bitcoin has matured. In 2013, Greg Maxwell proposed CoinJoin as one of the first solutions; it simply mixed together bitcoins, making it harder to correlate them. That same year Adam Back detailed "bitcoins with homomorphic value", which would eventually become the Confidential Transactions of Blockstream's Elements Project. Back took a different tack by blinding the contents of a transaction, so that people outside the transaction could only see that it occurred (and what the mining fee was). The fact that later non-Confidential Transactions could leak information about previous Confidential Transactions is probably what led to the creation of fully privacy oriented blockchains, such as Monero in 2014 and Zcash in 2016, each of which took different approaches to secrecy.
Obviously, there is interest in increased blockchain privacy: it's been one of the driving forces for cryptocurrency adoption. This transactional secrecy has a variety of advantages, the most crucial of which is fungibility: with true privacy, it becomes impossible to trace the provenance of an individual transaction, which is crucial for working currency; without it, the cryptocurrrency in individual transactions could be censored if the network did not like who used it or how it we used.
However, we must balance this growing philosophical desire for complete secrecy with the philosophies that have been a developed part of the blockchain from the start. Secrecy may actually enhance some of the blockchain's core ideals, such as its censorship resistance. And, it doesn't hurt others, such the blockchain's trustlessness: protocols like Blockstream's Confidential Transactions were explicitly designed to balance out the inputs and outputs of a transactions, allowing verification by anyone.
But that's not to say that secrecy doesn't have problems of its own.
The Dangers of Cryptocurrency Secrecy
One of the original goals of Bitcoin (and other cryptocurrencies) was to give power back

Cotswold Wildlife Park has experienced a baby boom with over 350 births from 50 different species so far this year.
New additions include a tiny Giant Anteater pup who is the third breeding success for parents Zorro and Zeta.
The last time they successfully produced an Anteater pup was back in 2016.
The public were invited to help name the newborn via the Park's Facebook page and chose 'Zena'.
Curator of Cotswold Wildlife Park Jamie Craig said: "Zeta has again proved to be an excellent and diligent mother. We are extremely proud of her here at the Park and it is great to see another healthy baby growing rapidly and exploring her surroundings from the safety of her mother's rather formidable back!"
Elsewhere in the Park, keepers are celebrating the arrival of Bactrian Camel Petra.
She is the first calf sired by first-time father Louis, who was named after Prince Louis of Wales as they were both born on the same day, and experienced mother Cleo.
The wild Bactrian Camel is classified as critically endangered and is thought to be one of the rarest large mammals on earth. Camels have a gestation period of approximately 360 to 440 days.
Section Head of Primates and Small Mammals, Natalie Horner, said it has been a very busy time on the Primates and Small Mammals section this year.
"Several new births to celebrate include our Colobus Monkeys, Titi Monkeys, Cotton-top Tamarins, Dwarf Mongoose and Naked Mole Rats.
"We're also thrilled with our latest additions to the Lemur troop, including the birth of one of the rarest primates on earth - the Greater Bamboo Lemur.
"With only 30 animals in captivity worldwide, we're one of only two zoological collections to have successfully bred Greater Bamboo Lemurs this year.
"And our pair of Crowned Lemurs recently gave birth to twins. Female Sava and her partner Izao are first-time parents and are doing a brilliant job of raising their youngsters."
It was also a remarkable breeding year for the White Storks.
Cotswold Wildlife Park is heavily involved in one of the UK's most ambitious rewilding programmes – The White Stork Project - which aims to restore wild Stork populations to Britain – a sight not seen since the 15th century.
2022 was not only the most successful Stork breeding season in the Park's history, with a record 33 chicks reared.
This year's chicks hatched at Cotswold Wildlife Park in May and were transferred to Knepp Castle Estate in West Sussex for release into the wild in August.
Other breeding successes so far this year include African Straw-coloured Bats, Dyeing Poison Frogs, Prairie Dogs, Binturong triplets, Parma Wallabies, Gundis, Black-cheeked Lovebirds, Pallas's Cats and White Rhino 'Queenie' who was named in honour of Queen Elizabeth II to mark Her Majesty's Platinum Jubilee.

GVSU Ravine Research
The ravines are a beautiful resource which should be protected, as well as a potential hazard to the surrounding infrastructure of the university if not carefully managed (Figure 1). The steep hillsides and ravines are currently undergoing rapid erosion, down cutting, and widespread slope instability. It is likely that this erosion is due, at least in part, to an increase in storm water runoff, which is directed to the ravines from impermeable surfaces such as parking lots and walkways.
Dr. John Weber has done previous studies with students which suggest that the down cutting rate over the past 40 years may be as much as an order of magnitude greater than it was prior to the construction of GVSU (John Weber, personal communication).
Dr. Peter Wampler and student summer scholar Patrick Womble are collecting data during the summer of 2006 to better understand the affect GVSU urbanization has had on the ravine system. Specific research questions that we hope to answer include:
- What is the flow volume directed toward the ravines from GVSU infrastructure? How does this volume compare to what would be expected from a non-urbanized landscape?
- What are the short-term and long-term erosion rates in the ravines? Are these rates changing in response to efforts to slow erosion such as rock gabions and other structures?
- How has urbanization and increased runoff in the past 43 years affected the sedimentation rates in the lower ravines?
- What areas of the ravines are prone to slope instability and are these areas related to areas of increased runoff due to storm water discharge to the ravines?
- How has erosion and sedimentation affected the water quality in the Grand River?
- What can be done to inform decision makers about erosion and sedimentation in the ravines so that future land use and facilities are sustainable?

Fundamentals of Fluid Flow in Porous Media

Chapter 5
Miscible Displacement
Fluid Phase Behavior: Tertiary Diagram
Ternary or triangular phase diagrams can be used to plot the phase behavior of systems consisting of three components by outlining the composition regions on the plot where different phases exist. The advantage of using a ternary plot for depicting compositions is that three variables can be conveniently plotted in a two-dimensional graph and mixture of different components can be easily represented. A ternary diagram for hypothetical components A, B and C is shown in Figure 5‑7.The phase behavior on ternary diagram is plotted at fixed pressure and temperature and If these three components were miscible at that special temperature and pressure then no multiphase region would appear on the diagram. Every point on a ternary plot represents a different combination of the three components. Compositions could be represented in ternary diagram as weight, mole or volume percentage. The volume percentage is used only when there is not significant volume change during the mixing. The vertexes represent the pure components, and the sides of equilateral triangle are scaled to represent the binary compositions of the three possible pairs.
There are three common methods used to determine the ratios of the three species in the composition. The first method is an estimation based upon the phase diagram grid. The concentration of each species is 100% (pure phase) in its corner of the triangle and 0% at the line opposite it. The percentage of a specific species decreases linearly with increasing distance from this corner, as seen in Figure 5‑7. By drawing parallel lines at regular intervals between the zero line and the corner (Figure 5‑7.a), fine divisions can be established for easy estimation of the content of a species. For a given point, the fraction of each of the three materials in the composition can be determined by the first. For phase diagrams that do not possess gridlines, the easiest way to determine the composition is to set the altitude of the triangle to 100% (that is equal to the sum of all altitudes from the mixture point to three sides) and determine the shortest distances from the point of interest to each of the three sides. The distances (the ratios of the distances to the total height of 100%) give the content of each of the species, as shown in Figure 5‑7.b. The third method is based upon a larger number of measurements, but does not require the drawing of perpendicular lines. Straight lines are drawn from each corner, through the point of interest, to the corresponding side of the triangle. The lengths of these lines, as well as the lengths of the segments between the point and the corresponding sides, are measured individually. Ratios can then be determined by dividing these segments by the entire corresponding line, by the so-called inverse-lever-arm rule, as shown in the Figure 5‑7.c.
In Figure 5‑7.c, point M is a mixture of ( Mb / Bb ) of component 'B' and (1 – Mb / Bb ) of binary mixture 'b' of 'A' and 'C'. These 3 rules could be applied to the combination of any two mixtures represented on the ternary. Figure 5‑8 shows two different mixtures represented by M1 and M2. Any mixture of M1 and M2 would be along line M1M2 . The point representing the composition of the final mixture would again be determined by applying the inverse-lever-arm rule along the line.

Phase relationship may also be represented on a triangular phase diagram Figure 5‑11. The diagram shows the phase condition at equilibrium at constant pressure and temperature. The plot is typical for hydrocarbon systems in which vapor-liquid equilibrium exists over regions of the concentration domain.

Figure 5‑9.a shows the phase behavior of mixtures of chemicals A, B and C. the diagram is on the pound mass basis and for a fixed T and P. three different mixtures of components A, B and C are contained in three vessels as shown in Figure 5‑9.b. The contents of three vessels are mixed together in forth vessel, which is held at the P and T corresponding to the ternary diagram. Describe the resulting mixture as follows:
 1. Find the final mixture composition, and show the overall composition on the diagram,
 2. Indicate whether the final mixture is one phase or two phase at specified T and P,
 3. If the mixture is two phase, specify the composition and amount of each phase.
Example 5-2 a) Ternary Diagram, b) Chemicals To Be Mixed
Figure 5-9: Example 5-2 a) Ternary Diagram, b) Chemicals To Be Mixed
Solution
For the first step we should determine the mass of each components (A,B, and C) in each vessel using the composition and mass of the chemicals. Table 5‑1 contains the results for this step and sample calculation:
Table 5-1: Composition Calculation, Example 5-2

To find the composition of the final mixture, mass of each component should be divided by total mass:

Reservoir fluids are complex mixture of hydrocarbons with components ranging from methane to C40+. In miscible displacement process a fluid miscible with the fluid reservoir during FCM or MCM process. This injected fluid alters thermodynamic properties of the reservoir fluid by changing the chemical composition of the reservoir fluid. Rigorous thermodynamic analysis needs identification of all chemical constitutes and their composition. But it is not practical. The experiences have shown that complex hydrocarbon systems can be represented with groups of hydrocarbons that preserve many of the important properties of the system. The combined groups of the hydrocarbons are called "pseudocomponents". A decomposition of crude oil into CH4-N2, C2-C6, and C7+ components is a common example of "pseudocomponents". A typical representation of miscible displacement process is a "pseudoternary" diagram with C1, C2-C6, and C7+as pseudocomponents as shown in Figure 5‑11.b. generally possible grouping that is used frequently includes the following mixed components:
 - The first component represents a volatile pseudo component and most of the times contains C1, N2, CO2,
 - The second pseudocomponent is a mixture of intermediate hydrocarbon components such as C2 through C6, sometimes CO2 is grouped in this group.
 - The last group is essentially C7+ fraction of the reservoir hydrocarbon.
An important assumption in using pseudocomponents and a pseudoternary diagram is that the composition of the pseudocomponents does not change in the different phases.
Within the two phases region there are tie lines whose ends represents the composition of equilibrium phases (Figure 5‑11). Tie lines length shrinks toward the critical (plait) point where the properties of two phases are indistinguishable. The position of plait point changes with temperature at a fixed pressure. As Figure 5‑11.b shows, all composition represented by points (M1-M5) inside the two-phase envelop would separate into two phases (V1-V5 as vapor and L1-L5 as liquid), the relative amount of two phases can be calculated using inverse-lever-arm rule. The points outside the two phase envelop are representative of a single phase composition. The critical tie line is the fictitious tie line tangent to the bimodal curve at the critical point. The critical tie line is the limiting case of the actual tie line as the plait point is approached.
Ternary Phase Diagram
Figure 5-11: Ternary Phase Diagram
As the pressure increases, the two phase region shrinks, or in other words light-heavy miscibility increases (Figure 5‑12). No general statement is possible about the effect of temperature though the two phase region generally growth with increasing temperature.

According to this, Figure 5‑13 shows that any combination of components A and C, and any combination of B

Previously it was possible to use the SharePoint User Interface, our API and the Muhimbi Workflow Power Pack to control this merge process, but as of version 5.1 it is also possible to merge files using both SharePoint Designer and Nintex Workflow.
This post shows how to use SharePoint Designer to create a workflow that automatically adds a cover page to a document whenever it is created or updated. If the document is not already in PDF Format it will convert the file as part of the merging process.
The SharePoint Designer Workflow Activity is named Merge Documents into PDF. After adding it to your workflow you will see the following Workflow Sentence.
The following fields are available:
- These Documents: This field specifies the list of documents / URLs to merge (and convert if needed). Each file must be specified on a new line and each line may contains three ';' separated values
- File Path: The path to the file to merge or URL of web page to convert. This may already be a PDF file, but if not – and the file format is supported by the converter – then it will be converted first. The path can be relative to the current site (e.g. Shared Documents/Some File.docx) or absolute (e.g. /sites/Finance/Shared Documents/Some Folder/Some file.docx). SharePoint Designer Workflow Lookups are fully supported, which can be used to dynamically generate the path for the current file, e.g. [%Current Item:URL Path%]. In SharePoint 2010 always use forward slashes in your file path, see KB2529610. When specifying a file please make sure the path does not include the host name, e.g. 'http://your site/…'. If you wish to convert web pages then the path MUST start with http:// or https://.
- Include Bookmarks: The source file may already include PDF Bookmarks, or may be able to generate such bookmarks as part of the conversion process, e.g. an MS-Word file. Specify true to copy these bookmarks to the merged PDF file, or false to strip out any bookmarks. This value is optional
- Custom Bookmark value: The this field parameter (see below for details) can be overridden using the third parameter. Specify the name of the 'top level bookmark' for the file, specify "" to remove the bookmark for this document or don't specify anything at all to use the value stored in the column referenced by the this field parameter. For an example see the exercise below.
- This File: An optional filename (and path) to write the merged document to. When not specified, the same name as the document that triggered the workflow will be used with a '.pdf' file extension. Please make sure the path does not include the host name, e.g. 'http://your site/…'., see this post for details.
- This Field: In a way similar to the User Interface for the merge facility, it is possible to specify a name of the column which contents will be used to populate the PDF Bookmark for the merged document. For example, specifying name or title makes it very easy to jump between the various sections of the merged PDF file.
- Variable: List ID: If you wish to carry out further actions on the generated PDF file, e.g. perform a check-in, then you can optionally write the ID of the List the PDF was written to in a workflow variable.
- Variable: List Item ID: Similarly to List ID, the Item ID of the generated PDF file can optionally be written to a workflow variable.
OK, so that is the theory. Let's create a sample to automatically add a cover page to each document. In this example we will use SharePoint Designer 2010, but the steps for SharePoint Designer 2007 are nearly identical.
Download and install the PDF Converter for SharePoint. You will need version 5.1 or newer.
If not already installed, download and install the free SharePoint Designer for your environment (2007 or 2010).
Make sure you have the appropriate privileges to create workflows on a site collection.
Create, or navigate to, the Document Library that will be used for this workflow and add a simple MS-Word file named cover page.docx. This file can really be in any format and if its content is static it is recommend to use a PDF file for this purpose so it doesn't need to be converted repeatedly for every merge operation.
Open SharePoint Designer, open the relevant Site, create a new workflow, associate it with the Document Library used in step #4 and enable all Start Options to make sure the workflow is triggered when an item is created and updated.
Add a condition to check that the type property of the current item does not equal pdf. Otherwise the workflow will recursively trigger whenever the merged file is written to the same document library.
Add the Merge Documents into PDF workflow Action and click the these documents parameter.
Add a line for the location of the cover page, note that our Document Library is named Automatic Merging. There is no need to specify the optional Include Bookmark and Custom Bookmark values, although you can if you wish to.
The second file to merge is the one that triggered the workflow. Position the cursor on the 2nd line of the String Builder and click the Add or Change Lookup button. Select Current Item as the Data Source and URL Path as the Field from source. Click OK to close the Lookup for String window. We want to include the source document's bookmarks so enter ;true at the end of the second line.
Your String Builder should now look similar to the screenshot under step #8. Click OK to accept the changes.
In this example we want the (merged) output file to use the same name and path as the source file that triggered the workflow, so there is not need to change the this file parameter.
Click the this field parameter and select the field you wish to use for the content of the PDF Bookmarks. In this example we'll select Name.
We are all done, publish the workflow and add an MS-Word file with the content to merge to the Document Library. After a few seconds a PDF file will be created consisting of the cover page and the content. Open the PDF file and use the Bookmark pane to quickly navigate to the start of the 2 documents.

Love pulls our senses apart and makes
The objective in Music Interpretation Parameters is to visualize a song through typography, graphics and imagery. A chosen song was to be displayed though the collection of materials and manipulating their image through a projector. Projected images of those materials yielded a variation of results, including wide ranges of colors, shadows, and highlights of the specified materials.
To create metaphors and visuals for the song by Ellie Goulding-Love Me Like You Do from the movie Fifty Shades of Grey. A feather was chosen to represent the soft and light feeling of the song. The projected images of the feather were used to develop a visual style that reinforced the overall tone of the song.

MICA SCHIST.Mica schist is a common metamorphic rock that is produced by regional metamorphism. The shiny look of schist is one of its key characteristics. The schist also has a nicely developed foliation. The word foliation comes from the Latin "folia" meaning leaves
MARBLE is metamorphosed limestone. Limestone is a sedimentary rock that is mainly composed of calcite, derived from the shells of living organisms like clams and snails. Marble can be produced by contact or regional metamorphism. Marble does not develop foliation like schist, because the calcite crystals are all about the same size. There is no way for them to line up. Marbles often contain other minerals, such as quartz, mica, and hematite.

The Path towards Predicting Evolution as Illustrated in Yeast Cell Polarity

Abstract
A bottom-up route towards predicting evolution relies on a deep understanding of the complex network that proteins form inside cells. In a rapidly expanding panorama of experimental possibilities, the most difficult question is how to conceptually approach the disentangling of such complex networks. These can exhibit varying degrees of hierarchy and modularity, which obfuscate certain protein functions that may prove pivotal for adaptation. Using the well-established polarity network in budding yeast as a case study, we first organize current literature to highlight protein entrenchments inside polarity. Following three examples, we see how alternating between experimental novelties and subsequent emerging design strategies can construct a layered understanding, potent enough to reveal evolutionary targets. We show that if you want to understand a cell's evolutionary capacity, such as possible future evolutionary paths, seemingly unimportant proteins need to be mapped and studied. Finally, we generalize this research structure to be applicable to other systems of interest.

ynamical analogue of the "mechanical absement"!
 Usually, people believe that the only usual kinematical/dynamical variables are the n-th derivatives (specially the 1st, and 2nd are the most important according to the galilean/newtonian/relativistic or even quantum theories). However, some "more interesting" variables do appear when you perform "integrals". Absement or the reciprocal inverse of position (something like a quantum momentum p=1/x with h=1) is the presement! Perhaps, the invention of infinitesimal calculus and that we are focusing only (generally speaking) in the first, second or third derivative of "position" is just un accident that we choose "position" as the main variable. I have my own suspitions about these facts…
 Imagine an exotic exoplanet where the ETI discover calculus not by differentiation but by "integration". How would ETI write the classical equations of motion?And the quantum counterparts?
 With respect to the interpretation of
 A=\int T dt
 beyond to be interpreted as "a momentum", you can also interpret it as the "farness" of temperature during some time interval. Moreover, note that if you introduce the Boltzmann constant (natural units) there, then you get something that is pretty like an action/angular momentum!
 In fact, making the full analogy with the mechanical definitions, another interesting magnitude would be the thermodynamical analogue of the presement, something like
 B=\int \dfrac{1}{T}dt
 Essentially, introducing again a Boltzmann constant (in the denominator of course this time) we would get the time integral of the celebreted \beta=(k_BT)^{-1}. In this case, you have something like \sim \mbox{TIME}/\mbox{ENERGY}=\mbox{POWER}^{-1}. This magnitude would measure the "nearness" in the thermodynamical sense!
 In summary, we get:
 1) Your idea of the integral of temperature with respect to time is the analogue of the mechanical absement.
 2) That "momentum" of temperature measure somehow the "farness" of the thermodynamical equilibrium as t flows!
 3) The analogue of presement can be also worked out. It shows that the nearness of the thermodynamical equilibrium is somehow related to the inverse of the energy flow, a.k.a., power.
 What do you think?
 2. Aaron Denney says:
 Wouldn't H -> -H reverse time, and thus give a sign flip to momentum?
 3. Joerg Paul says:
 Very interesting article! I wonder, if it is possible to found dualities in the other parts of phyics like Firestones analogy. In rotational mechanics this is easy, just swap angle and angular momentum. But are there useful dualities in hydralics, thermal physics or chemistry?
 4. Bossavit says:
 The idea [of Firestone's analogy] is to treat current as analogous to force instead of velocity… and treat voltage as analogous to velocity instead of force!
 I believe your mechanical 'auto-analogy' will prove essential to understand this puzzle. But reasoning on *lumped* dynamical systems may hide things that would look clearer in the context of the mechanics of continua. I mean this:
 – Calling q the charge density and j the current density, we have
 (1) d_t q + div j = 0 (charge conservation)
 – Calling p the density of momentum and s the stress tensor, we have (in the absence of body forces, that would otherwise appear in the right-hand side)
 (2) d_t p + div s = 0 (momentum conservation)
 (The sign convention I use in (2) is not the standard one: The standard stress tensor is minus s. Doing this will enhance the analogy.) The difference between (1) and (2) lies in q being scalar whereas p is vector-valued (or rather, covector-valued, since the force field f = d_t p is better conceived as a field of covectors). But apart from this difference, (1) and (2) are strikingly parallel: Integrating them over a bounded domain D will give a balance of "stuff", electric charge in the case of (1), momentum in the case of (2).
 Now, take the integral form of (1) and (2) and let D collapse to a point ("lumping"). One obtains
 (1′) d_t [charge inside] = [current flowing in]
 (2′) d_t [momentum inside] = [force exerted by outside matter]
 and there we are: "current analogous to force", indeed, and charge analogous to momentum.
 5. Frederik De Roo says:
 P is defined to be the outward pressure of the gas on our piston. If this is positive, reducing the volume of the gas takes a positive amount of energy, so we need to stick in a minus sign. I could eliminate this minus sign by changing some conventions
 If you use tension instead of pressure, you might get rid of the minus sign without provoking colleagues at UCR?
 Actually, even though you mention "on our piston" I find the word 'outward pressure' somewhat confusing because I would define outward and inward with respect to the (outward) normal of a small element inside the gas, so for me pressure would point inward and tension outward.
 6. Arrow says:
 My bet would be the analogies are a consequence of the fact all kinds of motion have the same fundamental origin – whatever it is.
 - John Baez says:
 Yes, I agree. I'd say it's mostly about Hamiltonian and Lagrangian mechanics, which are the usual ways of understanding motion at the classical (i.e. non-quantum) level… but with few big extra twists: we're studying open systems, we're treating them as networks, and we're allowing dissipation. What I'm doing is warming up to present a mathematical theory of this stuff… which I'm still busy trying to learn/invent.
 - amarashiki says:
 I agree too, but with an addition…I believe that there is something BIG in all this analogy, and I think the key idea is to consider or better understand the origin of those kinds of motion. And my conjecture is that there are something else beyond Classical Hamiltonian/Lagrangian mechanics, even if we consider "dissipation"…If the origin of the analogies is that the origin of the motions is the same, what kind of physical principle "catches" all that. I mean, it can hardly be something related to classical mechanics since it "extends it". What kind of symmetry or invariance transformation is playing here?
 By the way, I have some questions for John…What about this "generalized momentum" of temperature:
 A^{(n)}=\int \int \cdots \int T d^nt or
 B^{(n)}=\in \int \cdots \int (1/T)d^nt?
 (1) What happens in the limit n\longrightarrow \infty? Can it make some sense?
 (2) What would happen in the case of the n-th jet derivatives d^n T/dt^n?
 Remark: In Cosmology, the statefinder variables in the Hubble luminosity distance relation relate important variables like the Hubble parameter,or some densities with the derivatives of the scale factor! So it seems that higher order derivatives make sense too in a "cosmomechanical" framework!
 - domenico says:
 I write this result in an other blog, so it is a repeat of one of my theories (I try to write here only new ideas).
 Each differential equation have an Hamiltonian, if we doubling the number of variable:
 0=F(y,\dot y, \ddot y, \cdots )
 0=\frac{d}{dt} F(y,\dot y, \ddot y, \cdots )=\dot y \partial_y F+\ddot y \partial_{\dot y} F+\cdots
 \left\{ \begin{array}{l} y = y_0 \\ \dot y_{j} = y_{j+1} \\ \dot y_n = G(y_0, y_1, \cdots, y_{n-1}) \end{array} \right.
 H = p_n G(y_0, y_1, \cdots, y_{n-1})+ \sum^{n-1}_{j=0} p_j y_{j+1}
 \left\{ \begin{array}{l} \dot y_0 = \ \ \,\frac{\partial H}{\partial p_0} = y_{1} \\ \dot p_0 = -\frac{\partial H}{\partial y_0} = -p_{n} \partial_{0} G(y_0,y_1,\cdots,y_{n-1}) \\ \dot y_j = \ \ \,\frac{\

It's July 26: It's time to take off to the Tundra Science and Culture Camp. For two decades, high-school-aged students from across the NWT have spent 10 days each summer at Yamba Tì (Daring Lake), immersed in science and culture.
The camp is held at the Tundra Ecosystem Research Station, itself a model camp designed with the latest in energy and waste reduction technology and powered primarily by solar and wind power. But that's not what keeps students and staff coming back year after year. For participants, it's the natural environment and the unique way Indigenous culture helps them learn about the world around them.
The Tundra Ecosystem Research Station is located 140 km northeast of Wekweètì, and 275 km north of Łutsel K'e. Participants access the site by float plane from Yellowknife, watching eagerly as the trees disappear during the 1.5 hour flight.
Students come from high schools across the NWT. Before they go choose their career paths, they get a unique taste of the territory they grew up in, with a program led by experts in Indigenous knowledge, culture and environmental science. By working and studying alongside Tłı̨chǫ elders, GNWT experts, educators, environmental stewards, and on-site graduate student researchers, students learn by doing and get a taste of what career possibilities could be open to them.
But it's where culture helps to contextualize the science that really has an impact on students. Participants learn about Indigenous knowledge, the Tłı̨chǫ language and human history, alongside science.
After wading chest-deep into the lake for an aquatic ecology session, students might return to camp to learn from Tłı̨chǫ elders how to make a drum and play hand games. They hike along the hill that overshadows the Research Station, part of the longest esker in Canada — a winding ridge of sand and gravel left behind by glaciers — that runs for 800 kilometres from the NWT-Nunavut border to the Acasta River, northwest of Wekweèti. Students reflect on how Indigenous peoples have safeguarded the land for millennium. They'll spot Ekwǫ̀, the Tłı̨chǫ word for caribou, and learn to Asìı naxıts'ǫ sıı, wet'à done ts'àhdı, share what you have, from Tłı̨chǫ Elders practicing Dene Laws every day. Be it a new or expanded Tłı̨chǫ vocabulary, memories of the colours of the land, or a story from every hike long and short, everyone leaves with unmatched experiences and understandings.

text: This study proposes a radial basis function network (RBFN) controlled three-phase induction generator (IG) system using ac-dc and dc-ac power converters. In this study, first, the indirect field-oriented mechanism is implemented for the control of the IG. The electric frequency of the IG is controlled using the indirect field-oriented control mechanism. Then, an ac-dc power converter and a dc-ac power inverter are adopted to convert the electric power generated by a three-phase IG from variable-frequency and variable-voltage to constant-frequency and constant-voltage. Moreover, two on-line trained RBFNs using backpropagation learning algorithm with improved particle swarm optimization (IPSO) are introduced as the regulating controllers for both the dc-link voltage and the ac line voltage of the dc-ac power inverter. The IPSO is adopted in this study to adapt the learning rates in the backpropagation process of the RBFNs to improve the learning capability. By using the proposed RBFN controller with IPSO, the IG system can employ for stand-alone power application effectively. Finally, some experimental results are provided to show the effectiveness of the proposed IG system.
