Euclidean distance and others: non Euclidean geometries [Part 3]

Every day, everyone asks itself about the best way to move from a point A to a point B. Usually, if you are always late like me, you want to pick the shortest way. To define the shortest way between two points can be really easy in some cases but not in all. All distances […]

Warning "The illusion of mind" is a very interesting topic but so hard and subtle to treat. In this post, I do not want to deal with such issue from a psychological point of view and, indeed, I have no knowledge to do it.  My aim is to play: in several circumstances human intuition is […]

An Odyssey to Discover Round and Squared Pizzas!

The Geometry of a pizza Hi, everyone. Today we’re going to speak about pizza! Yes, I’m not crazy! I perfectly know it’s a blog on maths! Indeed, we want to talk of geometry of pizza and why there are some people who prepare it round and some who prepare it squared…who is earning money from […]

Euclidean distance and others: metric...


Short sum up... In a previous post we talked about Euclidean and other distances... In that post we introduced the definition of Euclidean, taxi driver and infinity distances. Almost anyone of you remembers the minimum distance, at the end of the post we explained that the minimum distance is not acceptable as a measure because it does not […]

Game Of Math: The MaxEnt Algorithm and Game of Thrones.

Game of Thrones. Surely you're wondering how does Mathematics fit in Game of Thrones? Well I confess, I could use any other TV series to tell you what follows in this post, but honestly ... what is best than Game of Thrones (GoT)? The connection to Mathematics is not so much considered in the series but in […]

In these days I and a collegue of mine had a conversation on a recent law proposed by  Ségolèn Royal in French Parlament. Shortly, this law would provide a monetary refund for those who go to work by bike; the refund is proportional to the distance covered every day. After a moment, everyone of us started thinking at the main point of it; everyone knows that there are […]

1. Introduction. Mathematics has always had a tremendous impact on reality, bigger than you might think, lowering itself perfectly in the present but also anticipating and outlining the future. Even with less advanced than today's technological means, past discoveries changed our perception of the world, simply using theories and formulations. In this post we won't see […]

Cookies, clocks and soldiers: modular arithmetic!

Introduction and the 7 dwarfs It was October when one of my professors entered in the lesson room and said: “Once upon a time, Snow White wished to prepare cookies for the seven dwarfs. Obviously…with some conditions. She wanted to prepare the least number of cookies such that dividing them into 2 dwarfs there would […]

What is Applied Maths?


"Applied mathematics is mathematics for which I happen to know an application. This, I think, includes almost everything in mathematics." (Henry O. Pollack ) Probably there is no unique definition of applied maths. In this article we report some references that analyze the problem and  try to answer this question. One of the most generic definition is the […]
