the optimal pace problem

The Optimal Pace

For professional athletes, the goal of running a marathon is to complete it as fast as possible. However, this does not mean that the athletes are running as hard as they can all the time, as one cannot maintain this pace the entire marathon. Hence they need to find a maintainable pace at which they finish the marathon as fast as possible: the optimal pace problem. It turns out that this very general problem is occurring far more often in normal day life and in business than most of us realise. Furthermore, it turns out […]

Betekent automatisering minder werkgelegenheid?

Veel mensen maken zich zorgen over de gevolgen van automatisering. Deze mensen zijn bang dat hun banen vervangen zullen worden door robots en dat zij daardoor in de toekomst werkloos zullen worden.  Betekent automatisering echter wel werkloosheid? Een tegenstrijdig voorbeeld hiervan is de uitvinding van de geldautomaat in het jaar 1939. Het aantal bankbedienden (mensen die achter het loket of de balie werken) is namelijk in 1970 verdubbeld ten opzichte van het jaar 1939, oftewel voor de automatisering. Verrassend genoeg zorgde deze uitvinding dus voor meer werkgelegenheid. Wat doen deze bankbedienden nu dan? Hebben zij […]

Predicting the spread of the Coronavirus

Predicting the spread of the Coronavirus

With over 86,000 people infected and around 3,000 people killed, the new Coronavirus is something to be taken very seriously. The new virus which has been called Covid-19 was discovered in Wuhan, China earlier this year. Not only has it taken a big toll on the Chinese economy, other countries in the world are being affected by the virus as well. In order to tackle the virus, several organisations have volunteered to help China with the fight against the virus. Moreover, several scientists are coming up with models to predict where and when the virus […]

Analytical Darts

“Why is playing darts even called a sport? I could do this with my eyes closed!”: just one of the many prejudices a lot of people have when speaking about the oh-so controversial ‘sport’ darts. The fact that most of us only play darts when we are drunk and that most of the professional darts players you see on television are not in great shape does not really help getting these stereotypes out of the world. But trust me on this one: for mathematicians and statisticians, analysing the game of darts is a real sport! […]

Raadsel: kan jij deze dames uit elkaar halen?

Robert-Jan-Constantijn van Binsbergen tot Haerholte is dit jaar in Groningen begonnen met studeren en is meteen bij een studentenvereniging gegaan. Daar valt hem echter iets geks op: alle vrouwelijke leden van deze vereniging zien er bijna precies hetzelfde uit, en ze hebben maar twee haarkleuren: 85% van de dames is blond en 15% heeft donkerbruin haar. Wat ook opvallend is, is het feit dat maar liefst 20% van alle jongedames (zowel de blondines als de brunettes) haar haar in de andere kleur heeft geverfd. Robert heeft gehoord dat jij je statistiek vakken super succesvol had afgerond, […]

Written by AI

It was Sunday the 26th of January 10 pm, I had one day left to submit my article for peer review. I was contemplating. Not knowing what to write about. I was staring at my computer screen. No unfamiliar websites. Just websites I had searched for before. Time flew. But suddenly I realized something. Something peculiar. Something odd. I remembered reading an article a couple of days ago about artificial intelligence (AI). The article explained how organizations including The Washington Post, The New York Times, Reuters, and Associated Press, made extensive use of AI to […]

The math behind the English language

Like many other languages, the English language is based on grammatical rules. It contains all parts to make a basic sentence, such as nouns, adverbs and verbs. All of this has not stayed the same over time. Scientists have known for decades now that every language evolves in striking similar ways to adapt to the needs of its users. Not only the words, but also the grammar change and mutate over time, where new versions slowly rise to take over the older ones. This development is not a bad thing, since if English had not […]

Quantum computers

The danger of quantum computers

The idea of a quantum computer first arose in the late century. Richard Feynman was the first person to think of using the special quantum properties to solve difficult mathematical problems. A lot of progress has already been achieved. “Let’s see what the future of quantum computers has to offer.”   A basic understanding of quantum computers All computers work in basically the same way. They receive an input of data, manipulate the data in some way and finally give an output. Quantum computers are no different. But what makes them so special? Quantum computers […]

21st-century discrimination

The past decade has been the decade of artificial intelligence. With the abundance of data that is generated every day, more and more decisions are made using data analytics and algorithms. The rise of AI in the 21st century has been swift and it has made an impact on almost every field. However, just as many good things, artificial intelligence also has a downside which came to light when in the 1980s some staff members of St. George’s Hospital Medical School noticed a lack of diversity among their students. They started an inquiry to investigate […]

Guaranteed profit gambling

With over 1.6 billion people gambling at some point during a given year and over 4.2 billion people having gambled at some point in their lives, it is safe to say that gambling is booming. The risk versus reward element gives players a small rush of excitement and this is also the reason why gambling is so addictive for a lot of people. Lots of social events also include gambling, for example a poker evening. Long story short: there is a big chance that you will be gambling at some point in your life. But […]

Guess the number of M&M’s in the jar and win …

We have all seen it at least once in our life: ‘Guess the number of M&M’s in the jar and win …’. Unfortunately, most of us have never been able to give an accurate guess. However, there exists a concept that can consistently yield accurate guesses.  The wisdom of crowds is the concept that a large group of people has a higher collective intelligence than individual experts. This idea is applicable to a vast variety of instances including problem-solving, decision-making, forecasting, and policymaking. For example, some companies measure market sentiment via Twitter feeds. Data from […]
