Systems of Linear Equations

A few weeks ago I told the story of the exams I passed to enter the “Bachillerato Bilingüe” class in my high school. Among all the things we had to learn for the exam there was the substitution algorithm to solve systems of linear equations, which I’m going to quickly show here.

In November 1989 I passed the entry exams for the “Bachillerato Bilingüe”, aka the “Bilingual Bachelor”, a parallel study program that existed in my high school, and which gave access to the coveted “Baccalauréat International” degree; turns out my school was one of the few in Latin America that had that possibility, so there I went.

Translating the Formula for Primes to Rust With AI

After creating the C++ version of C. P. Willans’ formula for primes last week, I asked myself what other language is usually pitted as the fastest ever? And the answer, of course, is Rust.

Some of you might remember an article I published more or less a year ago, called “Mathematical Curiosities”. In that article I showed an indeed curious formula: the 1964 “Formula for Primes” by C. P. Willans.

One day, on a rainy Saturday evening in the autumn of 1989, I taught myself derivatives and integrals. Yes, I know, I didn’t have many friends back then, talk about peak nerd stuff.

The Argentine Brain Drain

Argentina is currently experiencing a brain drain so strong that it made the headlines on Swiss television. 200 Argies, many with higher education degrees or quite a bit of professional experience, are leaving the country… every day. To put that in context, that’s around 6'000 per month, or 70'000 per year.

I have a bit of a trip with Fibonacci numbers lately; here are many things I’ve learnt about them lately.

As far as I can remember, I have always been fascinated by computers. But in the crisis-ridden Argentina of the 1980s, buying one was beyond the reach of my mother. Actually, we did not even have a telephone back then.
