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 …
