In 1988 Germany banned a video game based on an anti-war film… for being too pro-war!
Platoon on the Commodore 64 was released in 1987.
In May 1988 the German BPjS put Ocean’s Platoon on the youth-endangering index.
The official reason? The game was “kriegsverherrlichend” and trivialised war — even though it was based on Oliver Stone’s Oscar-winning anti-war film. The BPjS concluded the movie’s message about the madness of Vietnam simply didn’t come through in the game.
It stayed restricted for 25 years until the listing automatically expired in April 2013.
Did you get past the 1st level? Did you discover the hidden Space Invaders game? 🧵👇

The good old days of CGA.
Alley Cat (1984 by Synapse Software) feels exactly like some programmer had a wild late-night coding session on too much coffee (or whatever they had back then) and just let the surreal vibes flow.
That limited 4-color palette (black, cyan, magenta, white) turns the whole thing into a piece of art... well, it's an acquired taste, I suppose. Add to that the squeaky PC speaker sound and you got yourself a game!
You're Freddy the alley cat, jumping bins, dodging dogs, climbing fences, then breaking into people's apartments to knock over vases, eat fish, and court Felicia while Cupid shoots arrows at you.
We've come a long way.

An Italian priest asked a simple question:
What do you get if you add
1 + 1/4 + 1/9 + 1/16 +...
and keep going forever?
The best minds in Europe, including the famous Bernoulli brothers, tried and failed for 85 years. Then in 1734 a 28-year-old Leonhard Euler cracked it, and the answer was π² divided by 6, with π showing up in a sum that has nothing to do with circles.

Crystals are geometry made rigid.Each form is fixed by exact angles and vertex equivalence.
A 60° equilateral face, a 90° cube, a hexagonal prism, these are not arbitrary drawings but the only shapes permitted by the 32 crystal classes.
Sphere packing reaches its densest lattice only when atoms occupy symmetry-equivalent sites. The numbered points mark positions that remain indistinguishable under rotation, reflection, or inversion.
Nature solves the packing problem by repeating the smallest possible unit that fills space without gaps.

In 1966, Mark Kac asked a simple question:
If you could hear every note a drum makes, could you tell its shape?
For a round drum like this one the answer is yes. However, in 1992 three mathematicians built two oddly shaped drums that play exactly the same notes, so in general you can't.

The sphere’s true volume is revealed by what remains after the cones are removed.
Every horizontal slice of the sphere is a disk of radius √(r² − z²). The cylinder with its double cone subtracted leaves an annulus of outer radius r and inner radius |z|. Both areas equal π(r² − z²). Cavalieri’s principle therefore equates the volumes.
Subtract the two cones from the cylinder: 2πr³ − 2·(⅓πr³) = ⁴⁄₃πr³. The sphere occupies exactly two-thirds of its enclosing cylinder.
Geometry finds equality in the slices we choose to compare.

Geoffrey Hinton once noticed that the tellers at his bank kept changing. When he asked one of them why, the teller didn't know, only that they got moved around a lot.
Hinton guessed the reason... if staff never work with the same people for long, it's much harder for a few of them to team up and cheat the bank.
That thought became one of the most useful tricks in deep learning. While a neural network trains, you randomly switch off about half its neurons at every step. No neuron can lean on a particular partner, so each one has to learn something useful on its own. The trick is called dropout, and it helped AlexNet win the 2012 ImageNet contest, which set off the modern AI boom. It's still built into many of today's networks.

Did you ever wonder why when CRT gaming you can look at the screen up close and it doesn’t hurt your eyes like a TV broadcast would?
Here is the science:
Both standard consumer CRT TVs and classic arcade monitors 15 kHz tubes running near 60 Hz. Flicker perception on a CRT depends mainly on refresh rate and the comfort difference between gaming and TV/Movies is to do with progressive vs interlaced content:
•Most classic arcade games (and 8/16-bit consoles) output progressive 240p. Every line is redrawn each frame, so the image is stable. The dark gaps people call scanlines are just undrawn lines, not interlace twitter.
•Consumer TVs were built for interlaced broadcast (480i/576i). On 480i, odd and even fields alternate, so high-contrast edges and fine detail can shimmer at 30 Hz when watching TV shows.
Therefore for CRT use 240p is comfortable up close while 480i is quickly tiring on the same television at a similar distance.
Now you know!

"Start Doing Graph Theory" is a free, 478-page textbook (October 2026) that provides a comprehensive introduction to graph theory, combining mathematical rigor with a problem-solving approach.
The book covers graph isomorphisms, paths and cycles, trees, directed graphs, Eulerian and Hamiltonian cycles, matchings, graph coloring, planar graphs, network flows, and much more.
It is a valuable resource for university students and anyone interested in developing a deeper understanding of graph theory and its applications. The book also includes numerous exercises that help readers put theoretical concepts into practice.
Definitely worth adding to your mathematics library.

Today is a mathematical date we won't see again for 78 years.

It's called a Pythagorean Triple Day. There are infinitely many Pythagorean triples, but only 12 dates this century satisfy the equation.Today is the last.
