The winners of the Nobel Prize in Economics 2021

On the 11th of October the Nobel Prize in Economics was awarded to David Card, Joshua Angrist and Guido Imbens “for their methodological contributions to the analysis of causal relationships”. Loosely speaking, these researchers are looking at ways to address several relevant problems in society, such as the effect of education on wages or the effect of immigration on employment levels. However, problems arise as there usually are no comparison groups, i.e. we do not know what would happen if the event would not have taken place.  However, these Nobel Laureates have shown that there […]

Why do we feel as though our friends are more popular than us?

Whilst this may appear as an insult, or a bleak depiction of one’s lonely life in comparison to the popular lives of others, this feeling is actually a mathematical phenomenon that appears regularly in everyday scenarios. This phenomenon is known as the “Friendship Paradox”. – Lydia Nawas

The groundwork for a sustainable economy

Lately, I realized that I was not as concerned about the climate as some other people around me. Personally, I did not think about the consequences that my own behavior had on our climate. Our usage of plastic bags for our goods, fossil fuels, and other unsustainable human endeavors, are not without consequences. Sooner or later, we will have used up most of the earth’s precious resources and now is the time to find alternatives for solutions for our overconsumption. Because in the end, climate change, is a product of our over consumptive behavior. There […]

Simpson's Paradox

Simpson’s Paradox

In 1951 Edward Simpson published a paper discussing the interpretation of contingency tables. He discusses a phenomenon that is still occurring in today’s statistics. It is called after his own name, Simpson’s Paradox.  An Example Simpson’s Paradox can be explained with a simple example. Suppose we are developing a vaccine to prevent a deadly virus from killing people. After years of research, we have finally found a vaccine that could work. Before it can be distributed across the world, it has to be tested first. To keep this example very simple, suppose that there are […]

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 […]

why time speed up as we get older

Why does time seem to speed up when we get older?

With a deep sigh you blow out the candles on the cake. Today is your birthday and the whole family is congratulating you. You should be happy, but something is troubling you. Last year seems to have passed so quickly, even quicker than the year before. When you were younger, you never understood why your parents were always complaining about how the years went by so fast, but now you’re beginning to realise what they meant. Luckily, you’re not the only one that experiences it. It’s namely the story that everybody seems to understand; life […]
