Solving Mixed-Integer Semidefinite Programs
Vortragender: Prof. Dr. Marc Pfetsch
Semidefinite programs try to optimize a positive semidefinite matrix subject to linear inequality constraints. This class can be extended to mixed-integer semidefinite programs in which some of the variables are required to be integer. This forms an interesting class of optimization problems with many applications. This talk will introduce new methods as well as techniques that can be generalized from the linear to the semidefinite world. This includes presolving methods, e.g., fixing of variables, bound strengthening etc. Moreover, handling of symmetries and so-called conflict analysis can be adapted and have a positive impact on the performance. The impact of the methods will be illustrated computationally, using SCIP-SDP, an open-source solver for mixed-integer semidefinite programs based on SCIP.

While I’ve never been great at maths, the subject, I have always been good with numbers.
But there were a few things I could never get my head around.
Percentages and fractions chief among them.
The way it’s taught in schools is either wrote memorisation—that 1/10th is equivalent to 10%—now remember that and a dozen other common fractions, or a convoluted way of converting that gets even trickier when you’re talking improper fractions like 2 and 7/4s—which I can now easily see is 375%.
How did I get my head around it?
By playing the Legend of Dragoon of course.
It’s my favourite game of all time. It has a beautiful and compelling story, excellent battle mechanics, perfectly suitable music for each area, and actually lives up to the nostalgic feels I get when I play it after all these years.
But it also taught me (in concert with my inquisitive brain) how to calculate percentages quickly, easily, and accurately in my head.
Well there is a mechanic in the game called ‘Guard’. When you guard, you regenerate 10% of your health and mitigate incoming damage by 50%.
I learned that you regenerate 10% of HP from the Prima Guide (the game, PlayStation One, and guide were all purchased second-hand)—I’d never have normally bought a guide.
As you can see, Dart used guard and is recouped 10% of his maximum health pool by doing so.
As someone who loved games, created my own worlds, documented my favourites by making websites, filling binders with notes, creating hand drawn maps, and planed to make my own games, I wondered whether 10% a good number, or if it should be more or less.
Some enemies hit like a truck, others barely tickle—I needed some numbers to determine whether 10% was fair.
What about 20%?
How do I find 20%?
Well logic dictates that it would be double 10%. I was already fine with maths so I had no trouble calculating that 122 HP (from the above example).
That’s too much you could heal up way too fast with that.
What about 15%?
How do I find 15%?
Well it’s half of 10% (5%) on top of the original 10%.
66 divided by 2 is 33. 66+33 is 99.
That’s when I realised I didn’t particularly want the game to be easier, 10% did feel about right.
But what if the game was harder.
What if you only recovered 7% when you Guard?
Well budding game designer/theorist Bradley was on the case.
I knew 5% was 33 from the above example, but 1 or 2 percent is nitty-gritty and awkward, how do I calculate that in my head?
Again logic to the rescue.
If 66 is 10% of 660 (100%), then it’s 1/10th. Breaking down 66 (10%) in the same way would give me X (1%).
So I moved the decimal in my head and realised 1% is 6.6. So 2% would be 12.2 (or 12 as the game rounds to nearest whole number).
So 33 (5%) + 12 (2%) would give me 45 HP when I’d Guard.
That might have made the game too challenging for 12 year old me (though I’d be keen for 5% now).
Then I started thinking more explicitly about the relationships between the numbers.
10% meant guarding 10 times from low HP would fill me up (excluding additional damage taken during each round)—that’s 1/10th.
20% meant guarding 5 times—1/5th each time.
15%, came out at 6(ish) times—1/6th each time.
7%, 14(ish) times so 1/14th each time.
Thanks to this game, maths has been easy.
When I need 3.5%, I find 10%, find 1% from the 10% and multiply that number by 3.5.
When I need 20.5% I find 10%, double it. Find 1% from the 10% and halve that. Add the two together.
You can get into fractions of a percent too.
All it took was some logic and a catalyst to get me thinking.
School was never going to do that, but Legend of Dragoon did.
Post 7/30 (30 day blogging challenge #2—writing quickly) [Over 30 minutes]


The CERC ECD Grant provided me with the opportunity to attend the Summer Institute for Statistics for Big Data (SISBID), held at the University of Washington, July 19 to 24, 2017. I attended two SISBID modules explaining and demonstrating the application of modern statistical techniques for the analysis of biological Big Data.
The first module discussed supervised learning techniques applied to high-dimensional data, such as performing regression, classification, and survival analysis. Practical examples and exercises were part of this course, and the attendees participated in the discussion of the common limitations of this increasingly popular field in statistics. The techniques discussed and exercises were demonstrated in R programming language.
The second module focused on unsupervised learning techniques for biological Big Data. Unsupervised techniques aim to discover patterns when outcomes have no associated observations and learning is based solely on the data structure. The techniques discussed during this module covered data dimension reduction, clustering analysis and classification, and network analysis with graphical models. During one of the course sessions, the combined use of the unsupervised concepts for real-world problem solving was also explored using examples and exercises. Though most of the course focused on the application of supervised and unsupervised learning to high-dimensional data sets, such as those in the fields of genetics and biomedical imaging, the techniques discussed can be applied to new fields in statistical analysis.


I moved in to a new place. Compared to the old place this one is very spacious. We rented a two bedroom apartment. When I said we, I meant myself and my friend Eldho. He is a Ph.D. student in School of Mathematics whom I met during my maths course last semester. On top of that he is a deacon! (Ph.D. in Mathematics and Masters in Theology, nice combination huh!)
This link gives a glimpse of my place.
That’s all for now..
It is a cute place. Thank god you mentioned the “we”. I was having strange ideas after reading that first sentence!
Lovely place with a nice view. Good you clarified who ‘we’ are. Else, we would have started to get ideas ;P
Waiting for another life update!!


Mastery in Maths
Mrs. Andrea Turkmen and Mr. Lewis McGee are among around 100 expert mathematics teachers from schools across England taking part in the exchange programme as part of the Maths Hub Mastery Programme.
The purpose of the programme is to further develop the understanding and implementation of mastery approaches to teaching maths in Meir Heath Academy and The Priory School, and in local partner schools, they will be working with during the school year 2019/20.
The Mastery lesson will give colleagues from across the region the chance to see a demonstration of excellent classroom practice and to find out more about the wider Teaching for Mastery programme. Places are free but interested parties do need to sign up in advance, to find out more contact the local Maths hub by emailing email@example.com.
This is one part of the Teaching for Mastery Programme, run by the National Centre for Excellence in the Teaching of Mathematics (NCETM) in conjunction with the Maths Hubs Programme, and funded by the DfE. Funding for the four-year programme, initially amounting to £41m, was launched in July 2016 and over 200 schools have worked with the North Mids Maths Hub on the mastery programme since 2016.
There are 37 Maths Hubs, spread across England, each led by a school with a record of high achievement in maths, and of supporting, improvements in maths teaching and learning in neighbouring schools.


Present challenges of mathematics in oncology and biology of cancer
Marseille, CIRM December 7-11th 2015
This workshop aims at bringing together specialists and young researchers from different mathematical backgrounds (modeling, numerical simulations and analysis) and working in the field of oncology and from the world of oncology and oncopharmacology. This workshop would follows two previous workshops successfully organized in CIRM in 2009 and 2011. The interest of bringing closer the world of mathematicians, oncologists and biologists is getting more and more accepted and is a very promising way of setting trans-disciplinary collaborations. Important progresses have been achieved in the discipline of onco-mathematics in the last decade. Marseille, where several interdisciplinary collaborations involving several PhD students and post-docs have been developed in the last years, plays an important role in these advances.
The congress will focus on five topics issues, all of them concerning already ongoing projects in the Marseille's units :
Microtubules, migration and cancer
Cancer Stem cells, evolution of phenotype
Imaging and cancer
Through these sessions, we will put in light how mathematical modeling can help oncologists in terms of prognostic, prediction and therapy scheduling. We want to gather international experts in these five area of research in order to exchange and intensify the relations between the mathematical pharmacologists and oncologists communities.


Augmented Bernoulli Equation
There were a number of assumptions used in deriving the Bernoulli equation. One of these was that the flow had no viscous losses. An augmented Bernoulli equation is frequently used to include various head loss or head creation terms. A pump is a device that creates head, while friction losses decrease head.
The “head” form of Bernoulli’s equation is
Recall that Bernoulli’s equation was derived using the assumption that there were no viscous shear stresses (ie. the flow is inviscid). The Bernoulli equation is generally modified to include viscous losses after the fact. One such modification is friction losses in pipe flow. The Darcy friction factor states that the head loss is equal to
Where the friction factor, f, can be computed using a Moody diagram. The augmented Bernoulli equation that accounts for the frictional head loss is
Note that the friction loss term appears on the right hand side of the equation (the outlet side).
How friction losses are incorporated into the Bernoulli equation.

CSME/Mathematics Ph.D. Program Structure
This particular webpage on the CSME website provides information specifically for Mathematics Department doctoral students who wish to participate in the CSME Doctoral Program. The other participating CSME departments listed on the CSME Overview webpage maintain a webpage or document similar to this webpage which explains the particular details of their internal Ph.D. program, and how it is adjusted to allow a doctoral student in their specific department to participate in the CSME specialization. The overall design of the CSME Graduate Program, and the motivation for its development, is outlined on the CSME Overview webpage and also in the CSME Ph.D. proposal document, which can be found on the CSME Resources webpage. The detailed structure of the CSME Ph.D. Program can be found on the CSME Ph.D. Program webpage.
This page of information may be viewed as an example of how one participating department (in this case, the Mathematics Department) has adjusted the internal structure of its regular doctoral program to accomodate students wishing to participate in the CSME Ph.D. specialization; each department will likely approach such internal adjustments differently.
CSME/Mathematics Ph.D. Admissions Procedure
Admission to the CSME Program as a new incoming mathematics graduate student requires joint admission by both the mathematics department admissions committee and the CSME admissions committee. This is done through coordination between the two committees, without a separate application to the CSME Program. A student applying to the mathematics department who also wishes to apply to the CSME program simply chooses "Computational Science" in the "Current Area of Interest" section of his/her online application. Existing mathematics graduate students who wish to obtain the computational science specialization to their PhD through the CSME Program must also apply for admission into the CSME Program even though they have already been accepted into the mathematics department; admission to the program is then decided by the CSME admissions committee. Participation in the CSME Program will impact the choice of course work in the second year of your studies, so it is important to apply early in your graduate career at UCSD. The application process for existing mathematics doctoral students consists of a short email to the primary administrative contact for the CSME doctoral program, who also plays the role as the CSME/mathematics administrator. The contact information is given on the CSME Application and Admission webpage. The number of graduate student slots in the CSME Program available to each of the six participating departments is limited due to computing, space, and funding resources, and is also limited in order to maintain balance across the participating departments. Therefore, if you wish to participate in the CSME Program you are encouraged to apply early.
CSME/Mathematics Ph.D. Qualifying Examination Structure
The qualifying examination requirements for the PhD in the mathematics department for non-CSME mathematics graduate students is currently as follows. (See the Mathematics Department webpage for the most updated information.) Each graduate student must pass three written qualifying exams within a specified time period; the first exam is in real or complex analysis, the second exam is in algebra or applied algebra, and the third exam is in one of numerical analysis, topology, or statistics.
Mathematics graduate students who are participating in the CSME Program are released from one of the three exams in order to allow them to prepare for, and take, the common CSME qualifying examination. These mathematics/CSME graduate students will be required to take one exam in real analysis, a second exam in numerical analysis, and then the common CSME qualifying exam will play the role of the third exam. As described in more detail on the CSME Ph.D. Program webpage, the common CSME qualifying exam consists of the final exam in each of three quarter-length courses in three core areas of computational science.
Modifications to this default qualifying examination structure for mathematics/CSME graduate students is allowed under the following guidelines. With permission of the mathematics faculty serving on the CSME executive committee, the qualifying exam in complex analysis may be substituted for the real analysis exam; similarly, with permission of the mathematics faculty serving on the CSME executive committee, one of the other mathematics qualifying exams (excluding real and complex analysis) may be substituted for the numerical analysis exam. It is understood that such substitutions would have some research justification; a typical student would otherwise likely be best served by taking the default real analysis and numerical analysis exams.
All other requirements and timetables for the PhD in mathematics remain the same for students earning a PhD in mathematics and the specialization in computational science through the CSME Program.
CSME/Mathematics Ph.D. Core Sequences: Math 270ABC and Math 273ABC
When the mathematics department joined as one of the six core participating departments in creating the CSME program, it committed to designing and offering a project-oriented mathematics sequence (Math 273ABC) that would train CSME students in the core physical modeling, applied analysis, approximation theory, and computational algorithm tools that form the mathematical foundations of modern computational mathematics. This sequence would supplement the existing high-quality numerical analysis graduate courses that are offered by the mathematics department, and in particular would complement the existing Math 270ABC sequence that forms the basis for the Numerical Analysis Qualifying Exam for the Ph.D. in Mathematics. The detailed syllabi for Math 270ABC and other courses relevant to the CSME program can be found on the CCoM Courses Webpage.
CSME/Mathematics Ph.D. Specialization Transfer Policies
The current policies for transfering between the regular mathematics program and the mathematics/CSME program are as follows:
Current MA students who wish to enter the CSME PhD program must:
Students applying to the PhD program in mathematics should state whether they are applying to the non-CSME program, or to the CSME program.

Mathematicians love the Rubik’s Cube. There’s no denying it. They room amazed at just how such a seemingly simply puzzle can hold so plenty of secrets. There is always something brand-new to learn around the cube (if you space willing come learn, the course). Probably the biggest an enig of all, one that took end 30 years for mathematicians to crack is God’s Number.
You are watching: Algorithm to solve rubik’s cube in 20 moves
God’s Number, as plenty of cube enthusiasts will currently know, is the maximum variety of moves forced to solve any of the 43,252,003,274,489,856,000 combinations of the cube. It has actually been proven the this number is 20 (cube20.org), yet the discovery is fairly recent (July 2010). The term “God’s Number” was coined since the mind of a gift able to find the shortest succession of move to solve any scramble succession would need to be countless times an ext powerful 보다 our own, maybe to test millions of different combinations in the blink of one eye, something the mathematicians think only a divine being could possess.
This number may seem low, but theoretically it should be even lower. Only about 490,000,000 combinations call for the full 20 move to it is in solved. Return 490 million is a huge number, that is just a portion of the 43 quintillion feasible combinations (0.0000011328955% to it is in precise). The chances of generating a random scramble that deserve to only be fixed in 20 moves, no an ext no less, is about 1 in a billion. However, the number of combinations that can be fixed in 19 move is roughly 1.5 quintillion. This means that God’s Number is lot closer come 19 than 20, yet unfortunately even if only 1 scramble succession was difficult to settle in much less than 20 moves, God’s Number would still it is in 20.
History that God"s Number
Work began on the search for God’s Number earlier in 1981, as soon as a male named Morwen Thistlewaite showed using a complicated algorithm he devised himself the 52 moves was sufficient to solve any type of of the 43 quintillion different scrambles. This number began to fall slowly together better, more efficient methods were devised for fixing the huge variety of possible combine in the fewest move possible.
God’s Number can likewise be applied for various other twisty puzzles, such as using an initial Rubik’s Cube with certain restraints, or using smaller sized or enlarge puzzles. God’s Number because that a Rubik’s Cube resolved using only quarter turns (where no challenge can it is in rotated more than 90 levels at a time either clockwise or anticlockwise) has been proven much much more recently (2014) to it is in 26 moves.
God"s Algorithm because that 2x2x2 Cubes
God’s Number for the 2x2 puzzle (having only 3,674,160 various positions) has been proven to it is in 11 moves utilizing the fifty percent turn metric, or 14 using the quarter turn metric (half transforms count as 2 rotations). Unfortunately God’s Number has yet to it is in calculated because that the 4x4 cube, or higher.
The Devil"s Number
As we have discussed on the mathematics of the Rubik"s Cube page, every algorithm (permutation) has actually a degree in group theory. Every sequence of moves, if repeated enough times, will return the cube come the initial state. For instance a simple face turn requirements 4 repetitions, the R"D"RD algorithm needs to be used six times, going through 24 states.
Obviously, there"s an algorithm that goes with all 43,252,003,274,489,856,000 feasible positions that the cube. If we would use this algorithm to any kind of random scramble climate it would absolutely go thorugh the addressed state at some point.
The Devil"s algorithm is about about searching for the smallest number of moves essential to visit every place at the very least once. One algorithm, that applied repeatedly to any type of scramble will go back to the addressed state, no necessarily at the end of the the sequence. Devil"s Number is the amount of move in the shortest algorithm that does this.
Imagine that you could solve the Rubik"s Cube knowing just one algorithm. The difficulty is the this would certainly be extremely long. Finding the Devil"s algorithm is lot much harder than finding the optimal solution.
The fact is that us still don"t understand the Devil"s algorithm because that the 2x2x2 cube, in spite of that it has much fewer possible positions. So don"t mean this to be found for the Rubik"s Cube any type of time soon. Unfortunately the numbers room so imaginably high that also the 2x2x2 attempts have actually failed.
Let"s see an instance for the Devil"s algorithm. If we scramble a 2x2x2 cube permitting only fifty percent turns, we deserve to come earlier to the solved place repeating the following: R2 U2 R2 U2 R2 B2 R2.
Fewest move challengein official competitions
In main Rubik’s Cube competitions hold by the human being Cube association (WCA), over there is an occasion called Fewest relocate Count (FMC), which involves taking a random computer system generated scramble and solving the in as few moves together possible. A computer would be able to find the most effective solution possible that takes the the very least amount of moves in seconds, but in this event competitors have 1 hour to try and find the most effective solution that they physical can. The people Record for this occasion went below 20 moves many times. In 2019 Sebastiano Tronto (Italy) discovered a solution on an official competition in 16 moves. Store track that the advancement of FMC documents on the official WCA website here.
To conclude, God’s Number is a fascinating theory. It shows us just how such a straightforward looking puzzle can have over 5 and a half times an ext combinations 보다 there space grains the sand ~ above the Earth, and also it additionally proves that computer systems will always be infinitely better than people at nearly any task.

The Cube explorer program by the German mathematician, Herbert Kociemba is able to find the optimal systems in 20 procedures using the fifty percent turn metric (half transforms count as one move). Test our program which is making use of the very same algorithm. It"s looking for the systems in 20 moves but if the regimen doesn"t return any result below the moment threshold climate it switches come 24 measures which is also very close to the God"s number.


SERIES PARALLEL R-VALUE CALCULATOR
Calculate the average R-value of an assembly with a spreadsheet calculator and a tutorial video
Wouldn’t it be nice if you could push a button and see how much of a hit the R-value of a building assembly takes when you change the amount of exterior insulation, move the studs closer together, or leave an attic hatch uninsulated?
That’s what this spreadsheet does.
Incorporating the physics of series and parallel heat flow, it allows you to play around with the parameters in floors, walls, and ceilings to see what happens to the average R-value of the assembly. It’s great for anyone who makes decisions about how much insulation to use, where to put it, or how assemblies are designed and built.

Once your student understands counting with manipulatives and identifies where whole numbers fall on a number line, you can add using both of this visuals. Start with adding 1+1, put out two beans and push the one and one together. The student should come up with 2. Have the child count the one and one and then count it again as 2. Show the numbers with dots on a paper. One dot plus one dot equals two dots. Now add 2+1 and move through the same process.
1+1, 2+1. 3+1, 4+1, 5+1, 6+1…
Then add 1+2 and look at 2+1 again to show student that 1+2 and 2+1 gives you the same number of beans or dots. This is COMMUTATIVE PROPERTY. Shows that you can add in either direction and get the same thing.
Move to the number line now. Put your finger or a pencil on the number 1. Adding one means moving right by one number. This will also show that 1+1=2. Show it with beans, dots and number line for several examples.
Go back and ask if 4+5 = 5+4 to revisit commutative property.
Continue to practice single digit addition until student feels confident.

Calculators in the classroom is a constant debate. However, the Partnership for Assessment of Readiness for College and Careers, aka PARCC, had created their own Policy.
PARCC Calculator Policy for Calculator Sections of the Mathematics Assessments – Originally Released July 2012, Updated October 2014*
Grades 3-5: No calculators allowed, except for students with an approved calculator accommodation (see below)
Grades 6-7: Four-function with square root and percentage functions
Grade 8: Scientific calculators
High school: Graphing calculators (with functionalities consistent with TI -84 or similar models)Additionally, schools must adhere to the following additional guidance regarding calculators:
No calculators with Computer Algebra System (CAS) features are allowed.
No tablet, laptop (or PDA), or phone-based calculators are allowed during PARCC assessments.
Students are not allowed to share calculators within a testing session.
Test administrators must confirm that memory on all calculators has been cleared before and after the testing sessions.
Calculators with “QWERTY” keyboards are not permitted.
If schools or districts permit students to bring their own hand-held calculators for PARCC assessment purposes, test administrators must confirm that the calculators meet PARCC requirements as defined above.Calculator Accommodations:For students who meet the guidelines in the PARCC Accessibility Features and Accommodations Manual for a calculation device, this accommodation allows a calculation device to be used on non- calculator section of any PARCC mathematics assessment. Four-function with square root and percentage functions are allowable for grades 3-5. Please refer to the allowable calculator list for other grade levels.If a student needs a calculator as part of an accommodation in the non-calculator section, the student will need a hand-held calculator because an online calculator will not be available. If a student needs a specific calculator (e.g., large key, talking), the student can also bring his or her own, provided it is specified in his or her approved IEP or 504 Plan.
*Calculator specifications were released July 2012. One addition was made July 2014 to allow four function calculators with square root AND percentage functions. Additional guidance on allowable calculators for accommodations for grades was included September 2014. Additional clarification was added to the FAQs October 2014.
Frequently Asked Questions about PARCC’s Calculator Policy:
1. Can students use hand-held calculators for computer-based assessments?
Yes. For 2014-2015, students may use hand-held calculators on computer-based Mathematics PARCC assessments on sections where a calculator is allowable (grades 6 through high school), if they prefer. All hand-held calculators must meet PARCC requirements as defined in PARCC’s Calculator Policy.
It is recommended that schools identify which students prefer to use a hand-held calculator prior to administration to ensure that a sufficient number of calculators is available. Hand-held calculators are required for paper-based testing. Test administrators are responsible for ensuring hand-held calculators meet specifications, including ensuring the memory is cleared before and after administration.
2. Can students use their own calculators on PARCC assessments?
Yes. However, test administrators must confirm that the calculators meet PARCC requirements as defined in PARCC’s Calculator Policy.
3. Can students use calculators on PARCC assessments that are allowable for higher or lower grade level assessments?
No. In order to provide comparability across schools in the consortium, students must only use calculators that are allowable for their grade/course assessment. PARCC assessment items were developed with PARCC’s Calculator Policy in mind. Allowing for the use of a calculator that is designated for a lower or higher grade level assessment may unfairly disadvantage or advantage students and is, therefore, not allowed.
4. If a student takes an Algebra I course where a graphing calculator is used, but the student is taking a grade 8 PARCC assessment where a scientific calculator is used, which calculator should they use?
Calculator usage is assessment specific, regardless of the student’s grade level (e.g., a student who takes the assessment for a specific grade or course must use the calculator required by PARCC’s Calculator Policy for that assessment). In this example, the student should use a scientific calculator, since the student is taking the grade 8 PARCC assessment. A student taking the Algebra I assessment would use the graphing calculator for this assessment regardless of the student’s grade level. Schools should ensure students have ample opportunity to practice with the allowable calculator for their PARCC grade/course assessment.
5. Does my school have to buy new calculators?
Maybe. All schools participating in computer-based PARCC assessments will be provided an online calculator through the computer-based delivery platform. If a student chooses to use a hand-held calculator, he or she may either bring their own calculator or the school may provide the calculator. For paper-based assessments, all students in grades 6 and higher must have a hand-held calculator for the calculator portion of the assessment. Either schools must ensure they have a sufficient number of the appropriate calculators available or allow students to bring their own. All calculators must meet PARCC requirements defined in PARCC’s Calculator Policy.
Teachers need to make sure students know how to utilize calculators for their success not for the test but for future classes and their careers.
Following are photos from Miss Watson’s 7th-grade class in Peoria, Illinois. You can see that students are grouped or partnered, utilizing hands-on learning and graphing calculators. Students are engaged, utilizing math vocabulary and higher-level thinking skills in order to encompass their learning. Students are taking responsibility to fill learning gaps by learning from others. Teacher is the coach and not the center of learning. Changing to project-based learning in cooperative learning style using manipulative and calculators with the teacher as a resource will change the learning environment to productive experience for all involved. ~Sandy

A vibration is a wiggle in time; a wave is a wiggle in space and time. In this exercise, you will explore that connection by transferring the motion of the second hand of a clock (a vibration, even if a slow one), to a wave.
Print out the image of a clock and open the spreadsheet called Grapher. You will find both of them in the same item where you found these instructions.
Use a metric ruler to measure the displacement of the tip of the second hand every five seconds. That’s the distance above or below the center line that connects the 3 and the 9. Count the number as positive if the tip is above the line (towards the 12) and negative if below (towards the six). Enter each value in the tinted boxes in the Grapher tool and it will immediately plot them for you.
Then answer the questions based on your graph.
1) What is the period of this wave, that is, the time for one complete cycle, in seconds? The period of the wave is .02 seconds
2) What is the amplitude of the wave?
The amplitude is .01
3) If we had started from some other initial position – say, when the second hand was on the 3 – would the period still be the same?
4) Again, if we had started when the second hand was on the 3, would the amplitude still be the same?
5) So – again, if we had started when the second hand was on the 3, what would be different? Though we are starting from a later point, the period would still be the same distance, and amplitude is reliant on the period so if the period is the same then so is the amplitude. Simply the seconds from which we start measuring would be one notch behind, so the arch of each wave would be 5 seconds earlier.
6) Using the period from question 1, find the frequency of the wave. That frequency is of course way too low for us to hear. Please round you answer to three digits, not counting the starting zero; that is, round it to four decimal places total.
The frequency is .0125 Hz
7) If you had used the same picture of the same clock but had graphed the minute hand instead, what would change about the graph?
Nothing would change at all.
The frequency would change.
The amplitude would change. X
8) If you had plotted the motion of the second hand on your watch instead of the clock that you printed out, what would change about the graph?
Nothing would change at all.
The frequency would change. X
The amplitude would change.
9) Since you are plotting displacement on the y-axis and time on the x-axis, this is an example of a _____ graph.
10) Are you old enough to remember the 90’s television series Home Improvement, starring Tim Allen? He was always saying “more power” and blowing up one electric tool or appliance after another by trying to make it work faster.
Suppose that he was able to make a clock run so fast that the second hand made one full lap in only one-tenth of a second (0.10 s), and suppose that it tapped a water surface each time it reached the bottom of its motion. If the waves it produced were 4.0 cm apart, at what speed (in cm/s) would they travel?
The Waves would travel 40cm/s


“Vision in Elementary Mathematics”
The book, “Vision in Elementary Mathematics”, is about different topics in mathematics that a teacher could use to teach their students in an elementary classroom. It gives several ideas and techniques to teach students so that they can discover mathematics on their own. There are a variety of topics covered in the following chapters: “Even and Odd”, “Divisibility”, “An Unorthodox Point of Entry”, “Tricks, Bags, and Machines”, “Words, Signs, and Pictures”, “Sudden Appearance of a Practical Result”, “A Miniature Problem in Design”, “Investigations”, “The Routines of Algebra I”, “The Routines of Algebra II”, “Graphs”, “Negative Numbers”, and “Fractions”.
While reading this book I gained insight on how to get students to discover different techniques in mathematics rather than just being told. This concept was applied throughout the entire book. I strongly agree that it is important for students to discover concepts on their own rather than just being told a procedure and following it. By discovering a concept on their own, the students tend to remember the idea the problem was trying to convey. A quote from the chapter on divisibility states, “It is necessary for children to understand what is involved in a calculation. If they understand what is happening they can devise methods for themselves and can test by their own thinking correctness of their work.”
There are several methods of teaching discussed in this book. I believe most of the methods in this book are aimed at students who are visual learners. One of the examples that stood out to me was in the chapter “Investigations”. The book was discussing how many students believe (x+y)2 is the same as x2+y2. However, that is not the case. Let’s say x=3 and y=4. In this case (x+y)2 is 72 which equals 49 and x2+y2 is 32+42 which equals 25, and 49 ≠ 25. The way the book illustrated this was by creating a 7x7 table with one square representing 32 and one representing 42 and showing that there are still blank areas that would need to be completed in order to fill the square as shown below.
Overall, I would strongly recommend this book to college students who are going to school to be elementary teachers or an existing elementary teacher who is struggling to connect ideas with students. It shows many techniques that visual learners will be able to relate to and understand. It also does a great job on how to explain these concepts to your students in different ways. I found this book to be very interesting and of such value that I couldn't put it down. The value came from the various techniques and ideas on how to get the students to discover math versus just being told how to do something.


Choosing a Game
You can find currently three major categories of casino games: table games, gaming machines, and online slots. Most table games are played by at least one player at a time and don’t require the complete involvement of the casino staff to play. The most popular forms of table games include baccarat, blackjack, craps, and roulette. Online slots are played between computer players via a computer network, and may not require a casino gaming license.
Slots are simply just circular objects with a particular set of numbers on them that are turned over inside a specific period of time. If each of the numbers have been turned over, the object will undoubtedly be “saved” rather than tested on. Slots derive from probability, so the odds of hitting a jackpot are always exactly the same. This makes slots one of many easiest casino games to comprehend in terms of its odds. For that reason simplicity, slots offer one of the lowest barrier of entry for new gamblers and is therefore one of the widely played games at casinos.
A casino’s “edge” may be the advantage they have over other casinos. In the best case scenario, the casino with the best odds (based on historical betting patterns and current economy) is their casino edge. For the gambler, this implies an edge in chips or funds. To be able to boost your odds at winning more income, then it is important to know how to maximize your casino edge.
One technique of increasing the edge of one’s casino game is to minimize the standard deviation of one’s statistics. Standard deviation (also known as deviation) is a measure of the way the mean value of a statistic is distributed. For example, the standard deviation may be the arithmetic mean of the number of successes (on a random interval) that might 넷마블 포커 be expected if you were to bet the same number of chips as your bankroll. You can think of a typical deviation because the average of the random variables beneath the assumption that all of them are independent. Standard deviation can be useful when the selection of possible outcomes for a casino game is wide, nonetheless it has little use when there are various outcomes that are expected.
One of these of a popular type of casino game that uses standard deviation is video poker. Video poker is another game that uses random sampling, rather than expectancy or random chance. Many video poker players enjoy the advantage that they have if they maximize their standard deviation. They achieve this by playing in slots with the most aggressive payout chances-with the expectation that the return will undoubtedly be greater than the initial investment. These aggressive slot machine game players tend to get ahead on the amount of money line very quickly, but since they don’t value the big jackpots, they lose at a rate that is less than the perfect frequency with that they would play that slot machine.
Another popular type of casino game is poker. Like video poker, the easiest method to get ahead in a casino poker game is to go for the pots which have the highest odds of paying down. This kind of aggressive strategy can be utilized not only in slots but also in cards like baccarat and roulette. Of course, it is possible to get caught up in times where aggressive play isn’t advisable, and many people have been known to walk away from a casino with more money than that they had at the table. Therefore, it is important to choose your casino game carefully so that you don’t walk away with an increase of cash than you initially planned to place into the game.
Finally, you should keep in mind that both the long haul and the short run have payout odds. In a casino game where the long run payout it’s likely that better than the short run, playing conservatively for the long run may not be the best strategy. On the other hand, in a game where in fact the short run payout it’s likely that worse than the long run payout odds, aggressive play may be the best strategy. Therefore, it is advisable to balance your casino idea between the two to become successful.
Payout rates and payout odds are critical indicators in choosing casino games. However, the probability of winning a specific casino game are also very important. Playing in a casino game with terrible payout odds will surely make it less likely that you’ll walk away with money once you walk in. In addition, if you are interested in increasing your probability of winning a casino game, you really should consider playing on an odd number combination that has a good payout rate. For example, if you have the opportunity to play a thousand-game roulette wheel, you might want to play on that wheel for the next thousand games so as to increase your odds of winning.

I'm against the $85,000,000,000.00 bailout of AIG.
Instead, I'm in favor of giving $85,000,000,000 to America in a 'We Deserve It' Dividend.
To make the math simple, let's assume there are 200,000,000 bonafide U.S. Citizens 18 and older.
(Our population is about 301,000,000 +/- counting every man, woman and child. So 200,000,000 might be a fair stab at adults 18 and up.)
So divide 200 million adults 18+ into $85 billion -- that equals… Continue
