## How can we know something exists if we cannot find it?

The probabilistic method was pioneered by the Hungarian mathematician Paul Erdős, famous for his many contributions to combinatorics and graph theory, and it has since become an important tool in these areas of mathematics. Is this article you will learn how it works!

## Tales of the Tails: (Not so) mysterious Heavy Tail worldbeyond the Bell Curve

The scientific world would not be what it is today without normal distribution. It is the foundation of many statistical models for several good reasons. Most importantly, it appears commonly in nature. But this is only the tip of the iceberg.

## Picking the best route for order pickers

The routes that pickers in warehouses take are essential to efficiency. But which route is best?

## A peek into decision making in service systems

Often due to large waiting times customers abandon shops (online or physical), and owners don't realize that they have left. We call this a loss of opportunity. This is an important concept in queueing theory.

## The 100 prisoners escape puzzle

In this article, we will discuss a mathematical riddle that "seems impossible even if you know the answer". It is better known as the 100 prisoners problem.

## How do you decide who is the most important?

Imagine you’re in a remote village and only have a limited number of vaccines to distribute to protect the community from a deadly virus, who do you vaccinate?

A difficult decision, but necessary. Assuming that the disease is just as deadly for everyone in the community, the best way to prevent deaths is to contain the spread of the virus.

## The share bike mystery

How is it possible that bikes are so perfectly spread out that they are available from almost anywhere? Who are these bike fairies that distribute them evenly across the city? Continue reading if you like to find out who they are and what type of mathematics is involved.

## Interview with Marjan Sjerps: Mathematicians have a way of thinking that I really like

The Netherlands Forensic Institute (NFI) has a great deal of in-house knowledge in the field of forensic products, research and services, and provides many organizations in the field of security and law with reliable information from traces. Mathematical models are used within the NFI to understand the evidential value of the traces found.
