This is a neat research problem I came across. The idea is that you start with a total of “n” unit squares and you want to pack them into an object with a particular shape, in this case, we’ll pack these “n” unit squares into another square. The goal is to minimize the size of …

Just so everyone is clear: The only truly relevant difference between â€œmathâ€ and â€œmathsâ€ is usage. â€œMathsâ€ is commonly used in Great Britain, while â€œmathâ€ is standard in the US. Read more at Math vs. Maths Â« The Word Detective.

Donald E. Simanek has a nice Fibonacci webpage where he discusses some of the foolish claims that others make. You may have seen tons of those Fibonacci meme type images on the interwebz recently. David says: Of course much of this is patently nonsense. Mathematics doesn’t “explain” anything in nature, but mathematical models are very …

There was a negative Boy, who was confused about whether or not he should go to a radical party. The Boy was square, so he missed out on 4 Awesome Chicks and he cried until the party was over at 2 Am. Hint: x=[-b +/- sqrt(b^2-4ac)]/2a (Source)

In the episode, the professor invents a machine that swaps the minds of two people, but the swap can only happen once for a given pair of people. The problem …

0. Take any non-negative integer in base 10; for example, 4523. 1. Start at the most significant digit; in our example 4. 2. Now follow the hollow arrow once; i.e., we go to 1. 3. Now follow the solid arrows as many times as the next most significant digit; i.e., we follow the solid arrows …

Using pi calculated out to only 39 decimal places would allow one to compute the circumference of the entire universe to the accuracy of less than the diameter of a hydrogen atom. 3.14 backwards is PIE. The letter Ï€ is the first letter of the Greek word “periphery” and “perimeter.” The symbol Ï€ in mathematics …

Neat Fact:Every integer greater than 8 has at least two letters in common with each of its neighbours (source). Neat Trick:When the magician leaves the room, the trickees lay out eight coins in a row deciding which side is turned up according to their whim. They also think of a number between 1 and 8 …

Here’s a joke I made just for you guys! Your momma’s ass so big it’s bigger than a morass with gap 1,000,000! What’s a morass you ask? Well… in axiomatic set theory, a morass is an infinite combinatorial structure that is used to create huge structures from a “small number of small approximations”. Jensen defined …
