What do you know today that you didn't know yesterday?

In 1943, the US Army finally built up a sufficient supply of condoms for the troops stationed in England because the early ones, supplied by the British, were found to be “too small.”

no wonder the locals in England bemoaned the Yanks were “oversexed, overpaid, and over here”.

When you arrange prime numbers in a polar plot where the angular coordinate of the point is the prime number itself as radians and the radial coordinate is the prime number, you get this:





I couldn't believe it when I first saw it, so I made my own Python script to plot that.

^Algebra makes me cry - this makes me despondent.  You people and your math skillz - damn you all.

What maths skills?
I just "stole" a list of prime numbers from a very generous website and wrote a program to plot them in a special way.

isn’t that just saying a line on a polar plot for which every point has the same ratio between distance from center and angle from fixed reference would be a spiral?

Brain-breakingly weird discovery made via Wendigoon's Warren Hauntings video: How many movies based on the Amityville Horror would you think have been made?
FORTY. Seventeen have been released since 2020. Titles like "Amityville in Space," "Amityville in the Hood," "Amityville Thanksgiving," and "Amityville Karen" being four of the nine Amityville movies released in 2022 alone. My favourite title of the lot: The Amityville Vibrator.

Edit: Scratch that, the Wikipedia list is out of date. According to IMDb, there's actually 49. The most recent movie? Amityville Death Toilet.

Not quite. There are larger patterns happening.

But, if you plotted using degrees instead of radians, you would simply get a 180 lines through the origin.

The larger patterns are due to how well pi can be approximated by fractions, with the 'missing spirals' determined by exceptionally good approximations.

A similar pattern would be found if you plotted in a way that a full circle was the square root of 2 times some unit and plotted in that unit.

Ultimately, it is an expression of the fact that pi is irrational.

Bill Nye the Science Guy, while working for Boeing, invented the hydraulic pressure resonance suppressor tube, which minimizes the effect vibrations have on larger aircraft. He also holds a patent for an improved ballet shoe.

Adolf Hitler was nominated for a Nobel Peace Prize, after he occupied Czechoslovakia and just before he invaded Poland to start the most deadly and destructive war humanity had ever known.

This was after he banned German nationals from accepting the Nobel Prize.
