A triangle that changed the world

When you think of mathematics you imagine a sea of numbers, formulae and relationships. This is of course, as we know, quite often the case. However, mathematics hides quite interesting relationships you might have not yet thought of before. One of the most common...

Why all horses have the same colour

Why all horses have the same colour

What if I told you that all horses have the same colour? And that 2 = 1? And, to top it off, that I could prove it? You would probably say I’m delusional and that my proof must contain a mistake. However, there are proofs that do not contain mistakes which conclude...

Eating your cake the right way

Eating your cake the right way

For some reason I always have a hard time making inter-temporal decisions. Should I drink a few more beers tonight, taking into account that I have a lecture at 9 am tomorrow? Should I buy that new piece of clothing or save to accumulate some (possibly negative)...

Why do we count in base 10?

Why do we count in base 10?

What is two plus two? The realist will say four, the computer will say 100, and the cynic will say 5 – but which is correct? The reason we count in base 10 stems from the simplest fact: humans have 10 fingers. Understandable and logical, as this seems to be nature’s...

Are you living inside a black hole?

Are you living inside a black hole?

In 1915 Einstein wrote the leading description of gravitation in modern physics, also known as the general theory of relativity. This theory describes the universe so well that it never fails, except for the Big Bang and at centres of black holes, both are...

Why Mathematics is a Language

Why Mathematics is a Language

Mathematics is considered the heart of the beta-field, whereas languages are by definition alpha. One could say, therefore, that mathematics and language are direct opposites. Yet, mathematics is sometimes called the language of science and considering the definition...

The fourth side of a triangle

The fourth side of a triangle

Yes, you are reading this correctly: a triangle can have four sides. If this sounds strange, I have to agree: this statement could be formulated in a more nuanced way: when we look from the point of view of the associated circles to the sides of a triangle, the fourth...

The Infinite Monkey Paradox

The Infinite Monkey Paradox

To most people the notion of infinity is unfathomable. That has to do with the strange behavior some things demonstrate when the concept of infinity is introduced. Think for example of an infinite time horizon. No one knows what it feels like for an infinite amount of...
