Name a Theorem. By placing an order with TheoryMine, you name a newly discovered mathematical theorem¹.
This lets you immortalise your loved ones, teachers, friends and even yourself and your favourite pets! It may take upto 2 working days (excluding weekends) for our robot mathematicians to discover your theorem. Mathematical immortality? Name that theorem - physics-math - 03 December 2010. During my time as an eager undergraduate mathematician, I'd often wonder what it would feel like to prove a truly new result and have my name immortalised in the mathematical history books.
I thought that dream had died when I gave up maths to become a science writer, but Aron's theorem is now a reality – and I've got the certificate to prove it. While most mathematical theorems result from weeks of hard work and possibly a few broken pencils, mine comes courtesy of TheoryMine, a company selling personalised theorems as novelty gifts for £15 a pop. 2011 preview: Million-dollar mathematics problem - physics-math - 27 December 2010.

Vinay Deolalikar made waves in August when his draft solution to a mathematical problem that haunts computer science hit the internet. It's known as "P versus NP", and a correct solution is worth $1 million. Make way for mathematical matter - physics-math - 05 January 2011. Editorial: "The deep value of mathematics" WE ALREADY have solid, liquid, gas, plasma and Bose-Einstein condensate.
Now it seems we may be on the verge of discovering a whole host of new forms of matter - all based on mathematics. Π really is wrong! I've written recently about several different crackpots who insist, for a variety of completely ridiculous reasons, that is wrong.
But the other day, someone sent me a link to a completely serious site that makes a pretty compelling argument that really is wrong. Happy Tau Day? « Math Goes Pop! In the past, I’ve used this blog as a platform to make clear my mixed feelings about Pi Day, a math themed holiday celebrated every year on March 14th (3/14, har har) in honor of the beloved mathematical constant .
My thoughts on the subject can be found here. It would seem that I am not alone in my frustration. Why we have to get rid of pi for the sake of good math. Ancient puzzle gets new lease of 'geomagical' life - physics-math - 24 January 2011. An ancient mathematical puzzle that has fascinated mathematicians for centuries has found a new lease of life.
The magic square is the basis for Sudoku, pops up in Chinese legend and provides a playful way to introduce children to arithmetic. But all this time it has been concealing a more complex geometrical form, says recreational mathematician Lee Sallows. Deep meaning in Ramanujan's 'simple' pattern - physics-math - 27 January 2011. The first simple formula has been found for calculating how many ways a number can be created by adding together other numbers, solving a puzzle that captivated the legendary mathematician Srinivasa Ramanujan.
The feat has also led to a greater understanding of a cryptic phrase Ramanujan used to describe sequences of so-called partition numbers. A partition of a number is any combination of integers that adds up to that number. Someone told me that if there are 20 people in a room, there's a 50/50 chance that two of them will have the same birthday. How can that be?" This phenomenon actually has a name -- it is called the birthday paradox, and it turns out it is useful in several different areas (for example, cryptography and hashing algorithms).
You can try it yourself -- the next time you are at a gathering of 20 or 30 people, ask everyone for their birth date. It is likely that two people in the group will have the same birthday. It always surprises people! The reason this is so surprising is because we are used to comparing our particular birthdays with others. For example, if you meet someone randomly and ask him what his birthday is, the chance of the two of you having the same birthday is only 1/365 (0.27%).

It's rather obvious when a number is divisible by 2 or 5, and some of you probably know how to tell if a number is divisible by 3, but it is possible to figure out the division 'rule' for any number.
Here are the rules for 2 through 11... The last digit is divisible by 2. The sum of all the digits in the number is divisible by 3. The last 2 digits are divisible by 4.

Weierstrass functions. Weierstrass functions are famous for being continuous everywhere, but differentiable "nowhere". Here is an example of one: It is not hard to show that this series converges for all x. In fact, it is absolutely convergent. It is also an example of a fourier series, a very important and fun type of series. It can be shown that the function is continuous everywhere, yet is differentiable at no values of x. Web Design and Development. The On-Line Encyclopedia of Integer Sequences™ (OEIS™) Approximating Pi (non-Flash) Archimedes determined the upper and lower range of pi by finding the perimeters of inscribed and circumscribed polygons. By doubling the number of sides of the hexagon to a 12-sided polygon, then a 24-sided polygon, and finally 48- and 96-sided polygons, Archimedes was able to bring the two perimeters ever closer in length to the circumference of the circle and thereby come up with his approximation.
