Michael de Podesta has been doing the math on "Grime Dice" -- six sided cubes whose sides average out to 3.5, but whose face values are all radically different:
The interesting thing about these is that the odds of one die beating another are simple to calculate, but shift radically once you start rolling dice in pairs. It's a beautiful piece of counterintuitive probability math:
The amazing property of these dice is discernible when you use them competitively – i.e. you roll one dice against another. If you roll each of them against a normal dice then as you might expect, each dice will win as often as it will lose. But if you roll them against each other something amazing happens.
Dice A will systematically beat Dice B
Dice B will systematically beat Dice C
Dice C will systematically beat Dice A
So the fact that Dice A beats Dice B, and Dice Bbeats Dice Cdoes not ensure that Dice Awill beat Dice C. Wow!
And how about this: If you ‘double up’ and roll 2 Dice A‘s against 2 Dice B‘s – the odds change around and now the B‘s will beat the A‘s ! Is that really possible? Well yes, and just to convince myself I wrote a Spreadsheet (.xlsx file) and generated the tables at the bottom of the article. If you download it you can change the numbers to try out other combinations.
When I was a kid, I was terrified of farting in class. At home, it was no big deal: it was a daily fart festival with my family. But at school? TOTAL FEAR OF FLATULENCE. But then it dawned on me: EVERYBODY FARTS. And that’s one of the reasons why I’ve decided to write a graphic novel about how our bodies work. It’s about all the stuff that goes on inside our bodies daily, or throughout our lives, and that this stuff – whether it’s digestion, or respiration, or defecation – is necessary for us to live. And it gives you excellent come-back material if anyone teases you for farting in school!
Alan Turing and the codebreakers of Bletchley Park invented modern crypto and computers in the course of breaking Enigma ciphers, the codes that Axis powers created with repurposed Enigma Machines — sophisticated (for the day) encryption tools invented for the banking industry — to keep the Allies from listening in on their communications.
In 1948, the Institute of Applied Science commissioned an unknown illustrator to depict a fistful of squirming, terrified criminals caught in an authoritative fist, under the headline “CAUGHT BY THEIR FINGERTIPS” — they were advertising a home Criminal Investigation and Identification course.
The Lytro Illum dares to be different, boasting even more robust features than its first generation predecessor and a sleek design reminiscent of professional DSLRs. What’s so cool about it? Most cameras capture the position of light rays, producing a statoc 2D image.
