Neuralink, our new future?

Elon Musk has always been known as a man of revolutionary ideas, but the following idea might be the most revolutionary of them all. Last week on the 7th of May, he joined the Joe Rogan podcast. Here he revealed new details about his company Neuralink. The idea of this company is to implant very thin electrode wires in the human brain. In this way, it can cure almost any disease which has something to do with the brain. Furthermore, these devices would even allow us to communicate with each other without speaking. The technique […]

A lot of countries are having big outbreaks and the health care is having capacity problems. This is also one the many articles which you probably have seen about the coronavirus. What distinguishes this article from the rest is that it will dive a lot deeper into the mathematical models which researchers use to forecast the spread of the coronavirus. It is of course extremely important […]

How algorithms can choose your date

Feeling spontaneous, the mayor of Groningen wants to help all singles in the city. He wants to do this by organizing a date for every single in town. Since he thinks that you are pretty smart, because you study econometrics, he gives you the job of making all the combinations for the dates. How would you do this? In this case, we assume that we know the preferences of everyone. So from every man, we get a list with a ranking of women he prefers and from every woman we get a list with a […]

Sinterklaas special: The math of drawing lots

  It is almost that time of the year again: 5 December. In the Netherlands we also call it ‘pakjesavond’. Especially the children look forward to it throughout the whole year. A well known tradition around this time of the year is drawing lots: everybody gets a lot with the name of somebody else and you should buy a gift and write a poem for that person. An often encountered problem is that you do not draw another person but that you draw yourself. But how likely is it that this will happen? When I […]

The math behind your love life

Normally, when we apply mathematics in the real world it is to find patterns, to find the underlying dynamics of something which is complex at first sight. We use it for example to predict earthquakes, to compute the premium of an insurance or to find the optimal strategy how to run our business. These are things which follow patterns, they do not happen out of the blue and there is some underlying logic. However, not everything can easily be described by math. On that side, I would put love. Love is mysterious and a lot […]

Can econometrics save lives at sea?

Today we live in a world where data science and machine learning are getting bigger and bigger. The current output of data in the world is roughly 2.5 quintillion bytes a day and a quintillion means a number followed by 18 zeros! But what about situations when there is very little data but actions need to be taken? For example, when the coast guard is searching for a person lost at sea. The United States Coast Guard (USCG) encounters about 20,000 search and rescue cases in a year. This can be anything: a person who […]

The golden ratio

You have probably already heard about this sequence during one of your math classes. It is a famous one and it is called the Fibonacci sequence. This is of course a really simple sequence which everyone can understand. However, it turns out that it has some beautiful properties which we recognize in almost everything. Back in 1202, the Italian mathematician Leonardo Fibonacci wrote in his book “Liber Abaci” about a simple mathematical sequence. This sequence starts with the numbers 0 and 1 and the next number is just the sum of the two numbers before. […]

The PageRank algorithm

How did Google become so successful? What did the first search engine look like? The answer to these questions is related to a pretty basic mathematical concept which was revolutionary in that time. In this article I will tell you about the PageRank algorithm, which is the first and best known algorithm that Google uses. You may have heard the name earlier, Larry Page, he is one of the founders of Google and also one of the richest men in the world. He studied computer science at the University of Michigan and at Stanford University. […]

Founder talks: Jeroen Westerbeek

Last year they sold almost 10,000 watches, they planted one tree for each watch sold and next to that one of the owners was also still studying. This is the story of the company called WoodWatch, of which one of the founders, Jeroen Westerbeek, studied econometrics in Groningen. In this article I will tell you about him, about his company, and how he combines this with econometrics.   How it started The company WoodWatch was founded in 2013 by three friends who were all studying at the University of Groningen. One of them is Jeroen […]

Data analyse, de toekomst van de voetbalwereld?

Op het moment wordt de data van meer dan 90.000 voetbalspelers, 3500 voetbalclubs en 2000 wedstrijden per week bijgehouden. Dit zorgt natuurlijk voor enorm veel mogelijkheden om die data te analyseren en nuttige informatie eruit te halen. Misschien wordt het zelfs mogelijk de scouts te vervangen door een model die de meest geschikte speler voor een bepaalde voetbalclub genereert. Waar moeten we naar kijken in zo’n model en zal dit echt de voetbalwereld kunnen veranderen? Een bedrijf dat zich al een paar jaar op deze data analyses in het voetbal focust, is SciSports. Dit bedrijf […]
