Will the Netherlands win the UEFA EURO 2020?

We had to wait seven years for it but after two missed tournaments the Dutch national team are participating in the UEFA European Football Championship this summer. Therefore, we will see the so-called “Oranjegekte” again [1]. Obviously, the Netherlands only participates to win the UEFA EURO 2020 cup, even if it has only happened once before, in 1988. The Dutch won the final match 2-0, with goals coming from captain Ruud Gullit and tournament top scorer Marco van Basten. However, there is a similarity between then and now; the Netherlands also missed the tournament at […]

Home advantage in football: does it exist?

Football is the most popular sport of the world. It is to some extent even part of our culture. Especially during the world championships, the whole country is in the grip of this sport. Everyone basically wants the same thing: their team to win. A very important factor here is the so-called “home advantage”: teams who play in their home stadium tend to have an advantage over their opponents. However, now during the COVID-19 pandemic, football matches are played in empty stadiums. There are no yelling supporters anymore singing for their home team. This is […]

NFTs: the next big thing

For ages we have been looking at art as a physical collectible: The Mona Lisa is a painting, the Statue of Liberty is a huge copper statue, and the Balloon Dog (by Jeff Koons) is a stainless-steel sculpture. But in the recent months, a new kind of collectibles has arisen: the NFT. NFTs or non-fungible tokens are unique digital tokens that people can collect, like artworks. What makes NFTs special is the fact that they are intangible. They are one-of-a-kind assets in the digital world, that can be bought and sold, just like physical pieces […]

Giro d’Italia: the fight for pink and against Covid

It is 16:00h. The tension is building. They are coming. In the distance, you hear the sound of helicopter blades swelling. You look around. Every flag imaginable is present, people have dressed up and they are ready to party. You check the live stream, they started the climb. A helicopter has come into view, getting closer by the second. The sound of cheers resonance up the mountain. The first rider is spotted two hairpins below. Almost now. Then they take the last turn before the one you are standing in. The thundering roars pierce your […]

Newcombs paradox

Newcomb’s paradox

Let’s suppose that we have a game with two players. One is a person that will make a decision and the other is a supercomputer that will try and predict that decision beforehand. This computer has been tested many times and the testers have worked out that the computer can predict the decision of the player with 99% accuracy. The game works as follows: two boxes are placed in front of the player. One box is clear and contains a visible 1,000 euros. The other box is opaque, which means the contents are unknown to […]

Kolmogorov-Smirnov

The Kolmogorov-Smirnov Test

In statistics we are often estimating parameters and then, using some hypothesis test, we can find out if we should either reject our null hypothesis or not. Now in these tests we almost always rely on some known distribution of a so-called test statistic. Let us start by looking at an example of such a test. We will first need to assume that our sample follows a normal distribution with a known variance. Now we want to test if the mean of this normal distribution is equal to . Hence, we conduct the following test:   […]

The true winners of the Olympic Games

In July 2021 the 32nd Olympic Summer Games will take place. Or at least, that is the plan of the Japanese organizers and the International Olympic Committee. With the COVID-19 pandemic rates rising in Japan and global concerns whether organizing such a large event is responsible, it is not yet clear whether this plan is realistic. However, athletes around the world have no time to worry about this uncertainness. They need to be ready for when the time comes to defend the honour and glory of their country. This raises the question: which country actually […]

family name

Will your family name ever go extinct?

Nowadays, in most countries, everyone has a surname. Some names are very common, like “de Jong” in the Netherlands, or for example “Nguyễn” in Vietnam, where almost 40% of the population has this surname. On the other hand, some surnames are extremely rare. For instance in Thailand, where surnames were largely introduced in 1913 and no family was allowed to duplicate any existing surnames. Perhaps, you have a very rare surname yourself. Then you might have asked yourself this question: will my family name ever go extinct? In this article, I will demonstrate a mathematical […]
