The curve is also called the Gaussian curve after the German mathematician Carl Friedrich Gauss, who discovered many of the curve's properties. A graphed curve approximates the range and counts for many actual observations of facts that exist in nature and in civil society, such as weight and educational performance. Choose the fact you want a normal probability distribution for.
Consider how the example of normal occurrences will help you come to a conclusion. Resolve the decisive questions about your fact. Is a normal weight distribution useful to studying the weights in a medical patient population? Or is the population too unusual or abnormal to use a normal curve? Make a data set for your the observations you plan to chart. For each subject, take down the fact as a numerical value. Assign the number range for the numerical values, using the lowest observation to the highest observation.
Use the bell curve formula to calculate the y axis value for each x axis value. Y is the number of observations for an x value. The x is an observed value. Use the x sub order number for the calculation order and list order. Make a table of x values and the corresponding y values. Graph the bell curve for your fact. Using graph paper, arrange a graph with an x axis and a y axis. Draw the axis range to begin at your lowest value and end at your highest value.
Begin the y axis at 0, for no observations, and end at the greatest number of potential observations for any x value. The greatest potential observations is the highest number you believe you could find for your fact; for example, the highest number of male patients with a weight of pounds.
When you want to compare your observed facts to a normal distribution, view a graph of your observations and the normal curve you graphed. Compare how the actual observations fall in the areas within one standard deviation of the mean.
When you have a good data set for a normal population, 90 percent of your observations fall within 1. Differences form the normal curve tell you your population is above average, when the mean for the actual observations is to the right, or below average, when your observed mean is to the left. For facts that have normal distributions in the population, the higher your number of observations--assuming you have a random sample--the closer the observed curve will be to the bell curve.
Note that your bell curve does not have the two long tails, to the left and to the right, that the theoretical bell curve has. You curve has limits at the lowest and highest observed x values.

Wolfram Alpha computes integrals differently than people. It calls Mathematica's Integrate function, which represents a huge amount of mathematical and computational research.
Integrate does not do integrals the way people do. Instead, it uses powerful, general algorithms that often involve very sophisticated math. There are a couple of approaches that it most commonly takes.
One involves working out the general form for an integral, then differentiating this form and solving equations to match undetermined symbolic parameters. Even for quite simple integrands, the equations generated in this way can be highly complex and require Mathematica's strong algebraic computation capabilities to solve. Another approach that Mathematica uses in working out integrals is to convert them to generalized hypergeometric functions, then use collections of relations about these highly general mathematical functions.
While these powerful algorithms give Wolfram Alpha the ability to compute integrals very quickly and handle a wide array of special functions, understanding how a human would integrate is important too.
As a result, Wolfram Alpha also has algorithms to perform integrations step by step. These use completely different integration techniques that mimic the way humans would approach an integral. This includes integration by substitution, integration by parts, trigonometric substitution and integration by partial fractions.

Original post is here: ℙ : The Fascinating Applications of Pi in Modern Technology
Happy Pi Day everyone!
Why did the mathematician break up with pi? Because pi goes on and on and on…
Pi Day is celebrated on March 14 (3/14) every year, in honor of the mathematical constant π (pi). Here are some interesting facts and statistics about pi:
- Pi is an irrational number, which means it cannot be expressed as a simple fraction. Its decimal representation goes on forever and never repeats.
- Pi has been known for over 4,000 years. The ancient Babylonians and Egyptians both had approximations for pi, and it was later refined by Greek mathematicians.
- Pi is used in many areas of mathematics, science, and engineering, including trigonometry, geometry, calculus, and physics.
- Pi is also important in computer science, where it is used in algorithms for numerical analysis, machine learning, and cryptography.
- The first few digits of pi are 3.14159265358979323846. But pi has been calculated to over 31 trillion digits!
- The symbol for pi (π) was first used by Welsh mathematician William Jones in 1706. It was popularized by Swiss mathematician Leonhard Euler in the 18th century.
- The Guinness World Record for memorizing the most digits of pi is currently held by Rajveer Meena of India, who recited 70,000 digits in 2015.
- Pi Day was first celebrated in 1988 by physicist Larry Shaw at the Exploratorium science museum in San Francisco.
- In 2009, the US House of Representatives passed a non-binding resolution recognizing March 14 as National Pi Day.
- Some people celebrate Pi Day by eating pie (the dessert), or by participating in pi-themed activities and contests.
What do you get when you cross a river and a mathematician? A pi-thagorean theorem!
Pi is not just a mathematical concept, it’s a fundamental component of many technological #innovations that have revolutionized the world. From #aerospace to medical and finance, the applications of pi are diverse and far-reaching.
In the aerospace industry, pi is essential for calculating the trajectories of spacecraft and satellites. NASA – National Aeronautics and Space Administration, for instance, uses pi to determine the speed and direction of spacecraft, ensuring that they reach their intended destination accurately. Even minor discrepancies in pi can lead to significant errors in calculations, which can have disastrous consequences. That’s why pi plays a vital role in the development of new space technologies.
How do you know when a joke is a “pi” joke? It goes on and on and on…
Pi is also essential in the field of #medicine, where it’s used to calculate the volume and surface area of various body parts. This information is essential for designing prosthetics, implants, and other medical devices. Pi is also used in medical imaging, such as CT and MRI scans, to create accurate 3D images of the human body. These images can help doctors diagnose diseases and plan surgeries with greater precision.
What do you get when you cross a river and a mathematician? A pi-thagorean theorem!
In the finance industry, pi is used in various calculations, such as compound interest and mortgage payments. The formula for calculating the circumference of a circle (2πr) is also used to calculate the price of options in the stock market. The accuracy of pi is crucial in these calculations, as even minor errors can result in significant financial losses.
Inflation is like pi – it keeps going and going, and before you know it, your dollar is only worth 3.14 cents.
Pi is also an essential component of engineering and physics. Engineers use pi to calculate the stress and strain on materials, design bridges and buildings, and develop new technologies. Physicists use pi in calculations related to waves, such as sound and light waves, and to calculate the speed and momentum of particles.
How many pastry chefs does it take to make a pie? 3.14, of course!
But pi is not just useful in these industries. It’s also a fascinating mathematical concept that has captured the imaginations of people for centuries. Pi is an irrational number, meaning it can’t be expressed as a fraction, and its decimal expansion goes on infinitely without repeating. Mathematicians have been trying to calculate the exact value of pi for centuries, and to this day, they continue to explore the mysteries of this fascinating number.
What’s the official animal of Pi Day? The pi-thon!
- Geometry: Pi is essential in the study of geometry, which is the branch of mathematics that deals with the properties and relationships of points, lines, angles, and shapes. It is used to calculate the circumference and area of a circle, as well as the volume and surface area of spheres, cones, and cylinders.
- Trigonometry: Pi is also used in trigonometry, which is the branch of mathematics that deals with the relationships between the sides and angles of triangles. It is used to calculate the values of trigonometric functions such as sine, cosine, and tangent.
- Physics: Pi appears in many formulas in physics, including those that describe the behavior of waves, electromagnetism, and quantum mechanics.
- Computer Science: Pi is important in computer science, where it is used in algorithms for numerical analysis, machine learning, and cryptography.
Overall, pi is an important mathematical constant that has been studied for thousands of years, and its applications continue to be discovered and explored today. While the “cool” name and look of pi may contribute to its popularity, its significance goes far beyond just being a catchy symbol.
Why did the chicken cross the disclaimer section? To get to the funny part of the article!
This article might be funny, but pi is serious business. We’re talking about a mathematical constant that’s been studied for centuries, and that’s not something to be taken lightly. So, please, keep your laughter in check, and let’s get started.
Now, you might be wondering, how did I research this article? Did I read every book on pi ever written? Did I interview the world’s leading mathematicians and engineers? Nope, I used AI – #ChatGPT, a language model trained by OpenAI. That’s right, I fed a bunch of data into a machine, and it spat out all the information I needed. Sure, it might not be as #glamorous as traditional research, but it gets the job done. Plus, I can watch Netflix while the #AI does all the work. Win-win.
Why do mathematicians love pi? Because it’s irrational.
Now, I know what you’re thinking. “An AI wrote this article? That’s outrageous!” Well, let me tell you, it’s not as outrageous as you might think. In fact, AI is becoming more and more prevalent in our daily lives. Soon, robots will be taking over all our jobs, and we’ll be left with nothing to do but sit around and eat pie. But, hey, at least we’ll have plenty of pi to talk about, right?
What do you get when you take the sun and divide its circumference by its diameter? Pi in the sky!
In all seriousness, though, pi is a fascinating subject that has countless applications in various industries. And as much as we like to joke around, we should appreciate the hard work and dedication of the mathematicians and scientists who have devoted their lives to understanding this constant. So, let’s raise a slice of #π to them and hope that one day, we’ll finally figure out the exact value of this irrational number.
And with that, folks, I bid you adieu. Thanks for reading, and remember, pi are not square. Pi are round.

How to Calculate Percentage in Mobile Calculator – Find Out Percentage Easily
Today we’re going to learn about how to calculate percentage in your mobile calculator easily so now let’s begin…
How to Calculate Percentage in Mobile Calculator
So, here we will see a very simple yet very important topic, and we all should know about it how to calculate the percentage. So, although it seems very simple, very easy. It’s for those who are not able to calculate this. By the way, it is very easy, just be with us at the end of the article you will definitely learn how to calculate it.
Begin: Follow My Steps
Just open up your calculator, your phone app.
Once you open it you can see, for example, your son, your daughter, your friend, or somebody who has marks, something like 419 out of 500 means in the exam they have marks like 419 from 500. So the formula here is ‘just type 419 divided by 500’ and press the percentage button. In a calculator,
there would be something like a percentage. Just press that button and you can see, it is 83.8%. You can press the ‘equal to’ button as well, it’s 83.8%.
Similarly, you can randomly like test for some difficult numbers, like maybe 256 divided by marks, full marks are like 852. For example, I’m giving a complex kind of numbers to make this show how easily it works. Just click percentage that is 34%. In a real calculator you can press ‘equal to’ button as well.
Again, we can do something like for example, out of 350, somebody scored 305 divided by 360. Just keep percentage here and you can see it is called 84.72% percentage.So, it’s as this as I have shown you here. Another method is a little bit more conceptual like percentage. The main objective percentages per 100. So, if somebody’s scores like 250 out of 500, obviously he’s scoring half. If you calculate 250 out of 500, so how much you score from 100? … So just multiply it by 100 so it’s 50%.
If you do the same thing here, 250 divided by 500 and press percentage the same thing will come over here, that is 50.
So, there are two methods, either you just simply press the percentage or go by the conventional method conceptual method. That is, you divide the total number and multiply it by 100. For example, if it is 89 out of 200, then you can simply multiply it by 100 to get the percentage that is 44 5%.
If I do it by method 89 divided by 200 and press percentage, it’s the same 44.5%.
Hope so guys you liked reading this article. I tried my best as much as possible ways to make you understand everything clearly so hopefully, this article is gonna be helpful for you in how to calculate percentage in mobile calculator. Keep visiting us to learn many more things. Have a nice day!

We have 18 boxes, and we want to divide them into two equals stacks, so we want to divide 18 by 2. And the way we would write this, and we'll think a little bit more about what this means, we could write this as 18 over 2. This means 18 divided by 2. We could write it as 18 divided by 2, just like that, or we could write it as 18 divided by 2. V/CV. Moving on sometimes there’s just one consonant sound between the vowels, rather than 2.

The goal of these "how to" books is to provide the information and practice necessary to master the math skills established by the National Council of Teachers of Mathematics.
Each book is divided into units containing concepts, rules, terms, and formulas, followed by corresponding practice pages. For example, if your student received three A’s and one B, his grade point total would be 15 (3x4 = 12; 1x3=3; 12+3=15). Divide the grade point total by the number of credits attempted.
In the example above, if each course reflected one credit hour, your student’s GPA would be (15 grade points divided by 4 credit hours = ). Your child will learn how to multiply and divide, essential skills that are the foundation for virtually all future learning with numbers.
Much time will be spent making sure children understand the concepts of multiplication and division, and committing the 10 times tables and corresponding division facts to.

There are various statistical tests which can be used to assess whether changes in PAMCo data from period to period (or between publications) are actually real changes rather than the result of sample variation. For any estimate taken from PAMCo it is possible to work out a ‘confidence limit’. This is a way of expressing how much variation we might expect. For instance:
- Magazine X has estimated readership of 1,900,000 adults (3.5% of adults)
- The 95% confidence limits for this estimate are +/- 120,000
- This means we can be 95% certain that the true estimate for Magazine X is between 2,020,000 and 1,780,000 (3.3% to 3.7% of adults)
PAMCo has created two easy-to-use spreadsheets to:
- Find out the confidence limits for a particular estimate, be it readership or any other estimate on the survey.
- Find out whether the difference between two estimates is statistically significant
All users need to do is to enter the estimates they wish to test into the boxes shown on the spreadsheet, along with the population and sample size on which the estimates are based.


The IEEE has a standard IEEE-754 to represent floating point numbers , . It has three parts:
Sign: The sign bit is a single bit at the MSB where
0 = Positive Number
1 = Negative Number
Exponent: The exponent is represented with a Bias added to it in order to represent both positive and negative exponent. The exponent has a base of 2.
Exponent = Stored value at exponent bits – Bias
Stored value = 150
Bias = 127 (single precision)
Actual Exponent: 150 – 127 = 23
Exponent -127 (all 0s) and +128 (all 1s) are reserved for special numbers.
Mantissa (aka Significand): The Mantissa is composed of Fraction part that represents precision bits.
Example: 1101 = 1.101 x 2 3
Mantissa = 101
Exponent = 3
The IEEE 754 has two formats:
- Single Precision Floating Point (32 bit)
- Double Precision Floating Point (64 bit)
Multiplying Two IEEE 32 bit floating point number
Sign bit: If one of them negative then negative, otherwise positive
Exponent: The two exponents are added, since both are on bias 127, 127 is subtracted from the sum. Example:
Exp1: 200, Exp2: 150
Exp = Exp1 + Exp2 – Base = 200 + 150 - 127 = 223
Mantissa: The Mantissa is obtained by multiplying the two 23 bit input Mantissa with an implicit one added to MSB making two 24 bit numbers. The result is again truncated to 23 bits leaving the implicit 1.
Example: Mantissa = Mantissa1 x Mantissa2
1.01 x 1.0011 = 1. 011111, again the 1 becomes implicit
The result is 8 bit long in which Mantissa (8 downto 1) is taken instead of (7 downto 0) and 1 is added to the Exponent (truncate ).
Top Level Design Components:
24 bit Multiplier
Two 8 bit Adder
46 bit 1 selector Multiplexer
2 input XOR gate
Floating Point Multiplier Controller.
M1: 24 bit Multiplier:
The two mantissas, [input(22 downto 0)] are fed into a 24 bit multiplier with implicit 1 at the MSB. The multpllier is based on Booth Recoding Algorithm  and produces an output with size of 48 bit.
MX1: 46 bit 1 selector Multiplexer:
It is a special multiplexer that is used to sample the output. The 48th bit of the multiplier output is used as the selector of the multiplexer. If the 48th bit is 0, then multiplier output (45 downto 0) is selected otherwise to obtain the normalization, the output (46 downto 1) is selected. From the 46 bit output of multiplexer, mux_out(45 downto 23) is selected as the final truncated mantissa output (22 downto 0) of the floating point multiplier.
AD1: 8 bit adder:
This adder is used to add the two exponent parts [input(30 downto 23)] of the two inputs. The initial carry in is connected to the 48th bit of the multiplier to obtain the normalization when needed. It is 8 bit ripple carry adder.
AD2: 8 bit adder:
This adder is used to subtract 127 from the added exponents. The one’s complement of 127 is fed as the second input and a carry in of 1 is passed to the adder. The subtracted result is used as output (30 downto 23).
X1: 2 input XOR:
The two MSBs of the two inputs is passed through an XOR gate to produce the sign bit of the output (31).
Synthesis, Mapping, Placement, Routing:
After the design was successfully implemented and operational in behavioural simulation at ModelSim, the VHDL code was synthesized in XILINX ISE. In this phase, the synthesizer translates the VHDL code and produces the Post-Synthesis-Simulation-Model. Then it maps the model into different blocks of FPGA and generates Post-Map-Simulation-Model. Then it places the components and routes the interconnections between the different components and generates Post-Place and Route-Simulation-Model. This file was used to test the post route simulation result to check the functionality of the design.

I just was just having a discussion with someone about multilevel models, and the following topic came up. Imagine we’re building a multilevel model to predict SAT scores using many students. First we fit a model on students only, then students in classrooms, then students in classrooms within district, the previous case within cities, then counties, countries, etc. Maybe we even add in census tract info. The idea here is we keep arbitrarily adding levels to the hierarchy.
In standard linear regression, adding variables, regardless of informativeness, always leads to an increase in R^2. In the case of multilevel modeling, does adding levels to the hierarchy always lead to a stronger relationship with the response, even if it’s a tiny one that’s only applicable to the data the model is built on?
My reply: Not always. See here.
P.S. Since we’re on the topic, I should point you to this recent paper with Ben, Jonah, and Aki on Bayesian R-squared.

Dr. Firat Soylu received a University of Alabama Level 1 RGC grant, titled "Mathematical Processing Differences between Bilinguals and Monolinguals." Here is the abstract for his study:
With more than 25% of school students coming from immigrant households where the primary language spoken at home is not English, bilingual populations underperform in mathematics classrooms, where language of instruction in the classroom differs from their native language. In addition to sociocultural factors, this is partially due to bilinguals processing math knowledge differently compared to monolinguals. Differences between doing arithmetic in one’s native language and a second language have not been scrutinized extensively. To fill this gap, both behavioral and neural (Electroencephalography) measures will be used to examine how a group of adult bilinguals (Turkish/English) process simple and complex addition problems in their first (Turkish) and second (English) languages, and how arithmetic processing in bilinguals compare to English-speaking monolinguals. This study will be the first-step towards a research program that investigates bilingual math processing both in developmental and adult populations and will inform the needs of ESL (English as a Second Language) students in math classrooms.

Department Of Mathematics The combined Department of Mathematics and Statistics came in to existence in November 1976, with the major objective of developing it to a Centre of Excellence in this region in mathematical sciences and applications and to provide facilities for training, study and research in these areas. This Department was bifurcated to form an independent Department of Mathematics on 1st January, 1996.
The Department conducts an M.Sc. Degree programme, M.Phil. Programme in Mathematics and Ph.D. programmes. The students generally take up tegirls-birthday-party-ideas.comg positions or opt for research. Our students find admission to Ph.D. programmes offerd in various National Institutes such as IITs, IMSc, ISI, TIFR etc. Apart from giving instruction in post graduate courses, the Department has from the very beginning taken the leadership in promoting research in mathematics and its applications, especially in this part of the country. This was realized in a two-fold way one, by guiding young researchers to do their doctoral work and two, by conducting extension programmes which will improve the instruction at the school and college levels and encourage youngsters to take up research.

The moon Phobos orbits Mars (mass = 6.42 x 1023 kg) at a distance
of 9.38 x 106 m. What is its period of
is the period of orbit.
The equation that is useful in describing satellites motion is Newton form after Kepler's Third Law. The period of the satellite (T) and the average distance to the central body (R) are related as the following equation:
T is the period of the orbit
R is the average radius of orbit
G is gravitational constant
Here, given data
Substitute the given values, we get T as
Taking square root, we get
Two rockets are fired at each other with initial velocities of 150m/s150m/s and are 6000m6000m apart. The first rocket is accelerating at 5m/s25m/s2 while the second is accelerating at 15m/s215m/s2 . How far has the second rocket gone (in meters) when they collide? A :
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
When this will collide the total distance they would have covered would be 6000 m.
Hence at 13.72 seconds they will collide assuming they are launched at the same time.
The second rocket would have gone 3469.788 m when they collide
Which property is characterized by the ability to bend?
the answer is malleable

A 900-kg car traveling east at 15.0 m/s collides with a 750-kg car traveling north at 20.0 m/s. The cars stick together. What is the speed of the wreckage just after the collision?
Initial momentum = final momentum
In the x direction:
(900 kg) (15.0 m/s) = (900 kg + 750 kg) vx
vx = 8.18 m/s
In the y direction:
(750 kg) (20.0 m/s) = (900 kg + 750 kg) vy
vy = 9.09
The magnitude of the velocity is therefore:
v = √(vx² + vy²)
v = 12.2 m/s
What kind of light results when the total spectrum of refracted light is recombined? violet green white red?
Which statement is true? A) All waves travel at the same speed through any medium. B) All waves travel at the same speed if no medium is present. C) Electromagnetic waves require a medium, but mechanical waves do not. D) Mechanical waves require a medium, but electromagnetic waves do not. Eliminate
If a 25.5 kg child climbs 2 steps of 20 cm each, the work performed is
To practice Tactics Box 9.1 Calculating the Work Done by a Constant Force. Recall that the work W done by a constant force F⃗ at an angle θ to the displacement Δr⃗ is W=F⃗ ⋅ Δr⃗ =FΔrcosθ. The vector magnitudes F and Δr are always positive, so the sign of W is determined entirely by the angle θ between the force and the displacement.
See espplanation below.
The deduction of the formula given is this one:
We can assume that we have a constant force F acting on a point that follows a curve Y with a velocity v at each instant, we can define an small amount of work who occurs on a instant dt and we can calculate it as:
And we have that Fv represent the power at the instant dt and we can sum all the small amounts for the work in the entire trajectory with the following integral:
And M represent the trajectory from to
If we assume that the force is constant so then we can do this with the integral:
Where represent the displacement of the point along the curve.
We know that the fot product can be expressed on this way:
Where represent the angle between the force vector and the direction of the movement, so in general we have this:
And as we can see F and are scalars (assumed constant both) and not affect the sign of the work, so the only value that affect the sign of W is the angle since depedens of the cosine function who is maximum at 0 and 2\pi and minimum at
The vector magnitudes F and r are always postive, so the sign o W is determined entirely by the angle e between the force and the displacement.Submit Figure 1 off 1 part C


既然是选择不喜欢的，你只需要说说你为什么讨厌hiking club或者debate club即可，比如你可以说我大学时候老师让我参加了一个类似于debate club的社团。一开始我觉得挺好，但后来我发现我很难和这里面的成员打成一片，因为他们说话都很aggressive，都是暴躁老哥老姐，我实在是不喜欢这样的环境，这给了我不好的体验，所以如果让我选，我肯定选不给debate club资金。逻辑就是：我不喜欢，就赶紧给我消失。
I think the university should lower the budget for math club because I just don’t like it. I remember when I was in college, my professor was asking me to join something like a math club. At first I thought alright, it wouldn’t hurt to do some calculating or discussing with other students, but later when I actually got in the club, I found it so stressful to get in a discussion brainstorming with other students in the club, because it seemed like I was always a layman when it came to solving those advanced math problems, whereas they took it for fun, can you believe this? I felt like it’s only adding up to my pressure. So if you are asking me which one to lower budget for, I would definitely go for math club because I don’t like it.


Take a look at the newest and last die you may ever need – the D120.
Robert Fathauer and Henry Segerman of The Dice Lab designed this disdyakis triacontahedron that covers any roll you can make with a d4, d6, d10, d12, or d20. It is perfectly numerically balanced – opposing sides sum to 121, each corner, etc. The mathematical balance is thanks to Oberlin College professor Robert Bosch, integer programming, and persistence.
Take a look:
What game would you use this beauty for?


Updated: Jan 7
I recently came across an amazing thing, which actually blew my mind. It is like magic to a kid. I am fascinated about numbers and correlations, and if you are too, you either already know Benford’s law or you should definitely check it out.
Cutting the chase, Benford's law is an observation about the frequency distribution of leading digits in many real-life sets of numerical data. The law states that in many naturally occurring collections of numbers, the leading significant digit is likely to be small. For example, in sets that obey the law, the number 1 appears as the leading significant digit about 30% of the time, while 9 appears as the leading significant digit less than 5% of the time.
Benford’s law is almost applicable to everything if you can represent it in numbers. Like everything in nature follows the golden ratio, every pattern in nature follows Benford’s law. Not only that, but it is also applicable to population, taxation, elections, and many more... This is an important tool to identify any inconsistency in data sets.
You can check it out yourself, with the data around you like population of various states in your country or even your bank statement for the last 5-10 years. You will be amazed to find the numbers following Benford's law every single time if you are not manipulating the data.
BTW even with the 5% data manipulation (randomly), you will see that it violates Benford's law.
Of course, I got curious so, I applied Benford’s law to a Covid19 data set consisting of:
Date Range: Jan 2020 to Aug 2020
Parameters: Total Confirmed Cases & Total Deaths
And see for yourself that for all cumulative data, we see a perfect Benford’s curve. Amazing isn’t it?
I am sure you already guessed what I am going to do next and you want to see it too. So, let’s see what happens if we use the data for individual countries.
Below are the graphs for a few selected countries:
Looking at these graphs, we see that some countries are clearly following Benford’s law and others clearly not.
Let’s put them in three categories, based on how they comply with Benford’s law:
Low compliance with Benford's law shows that there may be some issues with the data being presented to us. Some visible call outs:
Canada, Japan, and New Zealand conform to the law for their number of confirmed cases but not for number of deaths
Australia and Russia conform to the law for their number of deaths but not for their number of confirmed cases
China, Italy, Singapore, UAE, and the UK do not conform for either, interesting!
Benford's law wouldn't lie, so who would???


Hi! I'm a post-doc at Stanford, advised by Shreyas Vasanawala and John Pauly. My research interests are in signal processing, medical imaging, data science and inverse problems.
I did my undergrad and PhD at UC Berkeley, where I had the pleasure to work with Miki Lustig for many years. I have worked on sparse representations, fast MRI reconstruction algorithms, and open-source software packages.
In my Berkeley days, I have also collaborated with Kannan Ramchandran on sparse FFT algorithms. And I did a wonderful summer internship with Peyman Milanfar on kernel methods for image processing.


The study of mathematics is mandatory from Kindergarten to Year 10.
By studying mathematics, students learn to work mathematically – developing fluency, understanding, problem-solving, reasoning and communication skills.
The syllabus consists of the following strands:
- number and algebra
- measurement and geometry
- statistics and probability.
In Year 11 and 12, the study of mathematics is optional. Courses offered include:
- Mathematics Extension 2 (Year 12 only)
- Mathematics Extension 1
- Mathematics Advanced
- Mathematics Standard 2
- Mathematics Standard 1 (Optional HSC examination)
- Mathematics Life Skills.
Mathematics Acceleration Program (MAP)
Rose Bay Secondary College has trialled a Mathematics Acceleration Program (MAP) and successfully seen students from the Year 9 cohort complete Stage 5, Year 9 and 10 content, within the single year. This means that when they enter Year 10, they would have already completed all the year 10 course work and will begin the Year 11 Mathematics Advanced and Extension 1 course. Due to the success of the trial program in 2022, RBSC's MAP will again be offered in 2023 to students commencing their Year 9 studies.
Acceleration is based on the principle of compression of work, not omission of work. Students who accelerate must achieve the required outcomes of the courses, but in a shorter time frame. Students must be prepared to work diligently during their Mathematics lessons, complete homework on a regular basis and in some instances, complete holiday homework.
Participation in MAP is through invitation only to students completing Year 8, where the Mathematics Department will gather student data including previous NAPLAN tests, Best Start data, all previous in-school Assessment Tasks from Year 7 and 8 and an Overall Mathematics Knowledge Exam sat in Term 4. Based on this data, and in consultation with students’ Year 7 and 8 mathematics classroom teachers, a judgement will be made regarding suitable candidates for the program.
Accelerated students must be self-motivated and independent workers, have a mature work ethic and the ability to manage a high workload. Students must be prepared to ask for help from their teacher as required.
The schedule will run as follows:
Year 8 – Overall Mathematics Knowledge Exam to be sat in Term 4. Successful candidates will be invited to take part in the MAP.
Year 9 – Completion of the Year 9 and 10, 5.3 Mathematics course.
Year 10 – Completion of Year 11 Advanced and Extension 1 courses. This may require students to take part in before and/or after school classes.
Year 11 – Completion of Year 12 Advanced and Extension 1 courses. Students will sit their Advanced and Extension 1 Mathematics HSC Exams. Following the HSC Examinations, students must attempt the first Year 12 Assessment Task in Term 4 of Year 11 for both the Mathematics Advanced and Mathematics Extension 1 courses. This is to ensure that should a student elect to repeat either or both courses in Year 12, they have completed all HSC course assessment tasks. (Note: HSC courses commence in Term 4 and HSC results are not issued until after the end of the academic year, usually in mid-December).
Year 12 – Accelerated students have several choices when they are in Year 12. These choices should be made in consultation with the Career’s Advisor, the classroom teacher, and the Head Teacher of Mathematics. The options are as follows:
- Accept HSC results and do not enrol in Mathematics in Year 12. This is one of the main aims of acceleration. If a student considers that they will need to repeat, they should NOT accelerate in Mathematics.
- Accept HSC results and progress to completing the Mathematics Extension 2 course. This course work would begin in Term 4, of Year 11. This is another main aim of acceleration; to give students the requisite skills to successfully complete the Mathematics Extension 2 course.
- Attempt Mathematics Extension 2 and repeat Mathematics Extension 1.
- Accept Mathematics Advanced HSC result and repeat Mathematics Extension 1 course only. Students must also repeat Mathematics Advanced coursework, but not take the HSC examinations.
- Accept Mathematics Extension 1 HSC result and repeat Mathematics Advanced course.
The College may, at any time, withdraw an invitation to be part of the MAP through a student’s demonstrated lack of application and/or consistently poor performance. A student and/or their parents may elect to discontinue participation in the program at any time. This would mean the student will revert to the appropriate course and class within their academic cohort.
If you have any questions regarding this program, please do not hesitate to contact Lauren Broit, Relieving Head Teacher of Mathematics, for more information.
