Basic wardrobe

The Norwegian mathematician Thoralf Skolem (1887-1963) is not a well-known figure, despite the number and importance of his contributions. He was the author of some 180 articles on diophantine equations, group theory, lattice theory, combinatorics […]

As the Second World War drew to a close, the Allies began the task of tracking down German scientists. The main reason – with the onset of the Cold War already looming – was to […]

In the mid-17th century, Europe experienced the last epidemics of bubonic plague. In Seville the main crisis occurred in 1649 (and which is so well recreated in the TV series by Alberto Rodríguez and Rafael […]

I apologize for bringing bad news. I hope no one wants to kill me. We all know that Thales was ‘the father’ of mathematical knowledge, the great origin of the ‘Greek miracle’ in geometry and […]

In these times of pandemic that we are living through, it is worth remembering a mathematical problem whose origins the tradition wants to situate in another plague. Specifically, the one that struck Greece in the […]

Among integers, prime numbers, whose only divisors are one and the number itself, are at the top of mathematical interest. The Indian mathematician Srinivasa Ramanujan began the study of the numbers that we can place […]

The number 1729 acquired a life of its own in the most famous of the anecdotes that weave the relationship between Hardy and Ramanujan. This is how Hardy described it in the obituary he published […]

“Adversity makes us wiser; prosperity destroys our appreciation of what is fair.” – Seneca. “We are in a time of crisis”: a phrase that is repeated, perhaps by every human generation. Who are we? Who […]

In our previous post, we learned about the partitioning problem, and here we will look at the contributions that Ramanujan made together with Hardy. Ramanujan’s work One of the topics that Hardy and Ramanujan worked […]

26 April 2020 marks the 100th anniversary of the death of the brilliant Indian mathematician Srinivasa Ramanujan who, with minimal academic education, made extraordinary contributions to mathematical analysis, number theory, series and continued fractions. Ramanujan […]
