Researchers have developed a mathematical formula based on the rhythmic movement of a sperm’s head and tail, which significantly reduces the complexities of understanding and predicting how sperm make the difficult journey towards fertilising an egg. Researchers at the Universities Read More …

## Parametric Prancing and Polar Dancing

When creating the parametric plot My three apps Goodgrapher Pro, PocketCas and QuickGraph+, together with Wolfram Alpha all give me the same result -luckily and not unexpected. However, asking for a spherical plot gives me two Read More …

## Primes, primes

A prime number is a positive integer that is divisible only by and . Now multiplication and addition interact rather strangely, in almost unfathomable ways. As a consequence, the distribution of prime numbers among the integers is somewhat random, and Read More …

## John Horton Conway: Genius at Play

I haven’t read a biography quite like Siobhan Roberts’ biography of John Conway: it feels more like meeting and entering a collaboration with Conway than a biographical account of his life and work. But the experience of being swept along Read More …

## How to move quite a big sofa around a corner (or not)

It’s an exciting day: You’ve just signed the lease on a new apartment.There’s only one problem. The hallway leading to your apartment has a sharp corner and your couch won’t seem to make it, no matter how much you and Read More …

## Squared ‘surprises’

It doesn’t always have to be complicated, math, to be fun. Take a number, add two to it, multiplicate these two, ad one to the stew, and you have the quadratic tern of the average of the first two numbers. Read More …

## Why you should have paid attention in math class….

….and why the amplituhedron is a fascinating concept. A few years old, the video takes some of your time, but worth while if you sit down for it. And – crazy people: attention around 12:00. Via IAS

## Let’s convex polytope

Well, well. The jungle gym you ordered a few weeks ago has finally arrived and, if the truth be told, it is not quite what you expected. What you are looking at after opening the package are a huge number Read More …

## Quantum sheep

The movie Blade Runner describes a future where society can engineer machines that almost perfectly imitate the behaviour of various living things, from sheep to human beings. These machines—referred to as “replicants”—interact with both the environment and other humans so Read More …

## How Laplace transformed …. well … a lot.

If you read a biography of people like Newton, Leibniz or Laplace you start to feel like a dummy. These people were brilliant in so many disciplines that it becomes dizzying. Pierre-Simon Laplace was born in 1749 in Beaumont-en-Auge (where Read More …
