Oxford University researcher David Robert Grimes developed a mathematical equation for the success rate of conspiracy theories. How long does it take for the truth to come out? One of the most […]

The coronavirus recession: the mother of all financial crises

The coronavirus crisis can be described as a generation conflict between the boomers and millennials. Sander Schimmelpenninck, a Dutch journalist, explains that it is logical that virologists may be the most important counselors nowadays, but the younger generations have to pay the bill for this economic downturn and don’t let anything hear from them. The millennials should realise that this crisis has big consequences. It may even have bigger consequences than the credit crisis in 2008, such as a double recession. In this article, I give an overview of the economic impact of the coronavirus. […]

Mathematical solution for gerrymandering

The fairness of the elections in America has been a point of discussing for quite a while. In 2012, Republicans won a majority of 33 seats in the House, but got 1.4 million fewer votes than their Democratic opponents. Such a result is a sign of gerrymandering, the practice of drawing voting districts to favour or disfavour certain candidates or political parties.

Rebus of Econometrics meme

Some students are already done with the exams and others are still studying to get as many ECTS as possible (in other words, surviving in the university library).

Despite a lot of available data and research, researchers still find it hard to answer the basic question about one of our most essential bodily function. In order to understand […]
