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.

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 […]

How to Lie with Smoking Statistics

In 1953 publiceerde Ernest Wynder een onderzoek over longkanker, waarbij hij het teer uit sigaretten met een borstel op 81 muizen smeerde. Het resultaat van dit onderzoek was dat 44 procent van de ingesmeerde muizen kanker had gekregen en slechts 10 procent van de totale groep was na twintig maanden nog in leven. Bij de niet-ingesmeerde muizen was er bij geen van hen kanker gevonden en 53 procent was nog in leven na twintig maanden. Vanzelfsprekend liet dit onderzoek vele mensen schrikken. Het gevolg hiervan was dat de aandelen van de tabaksindustrie flink in waarde […]

Predicting outcomes of tennis matches

In the article posted 4 weeks ago about the dark side of the tennis world I talked about how vulnerable the tennis sport is to match fixing. Bets can even be placed on every single point. However, is there a way to predict the outcome of matches and maybe even points? There are multiple articles that have tried to solve this problem. Many of these articles mention Markov models as I explained earlier. Now I will be digging deeper into this subject and try to predict a match between Rafael Nadal and Roger Federer. Markov […]

De Fermiparadox: waar zijn de aliens?

Op een mooie, heldere avond kijk je naar de sterren en vraag je je af: ben ik hier alleen? Is daar iemand? Buitenaards leven is een onderwerp dat iedereen wel in meerdere of mindere mate bezig houdt. Onlangs is er op de planeet met de uiterst origineel verzonnen naam K2-18b voor het eerst waterdamp op een planeet in de leefbare zone buiten ons zonnestelsel gevonden. Een mooie aanleiding om ons verder te buigen over de vraag: is er intelligent leven buiten aarde? Formule van Drake Laten we dit onderzoek beginnen met de formule van Drake. Hiermee […]

Optimizing Morse Code

Dot, dot, dot, dash, dash, dash, dot, dot, dot: SOS! You have most certainly heard of this so-called ‘Morse Code’. Morse Code is a code in which letters, numbers and even some punctuation marks are represented in dots and dashes. Back in the days, this was a very useful way of communicating over longer distances. With a so-called telegraph, people would send small electric shocks, where a short shock would be a dot and a longer shock would be a dash. They used predetermined intervals to indicate for example a space in a sentence. The […]
