Learnt an interesting thing today on this arabic course,
The original Arabic number system looked like this, the one we now use.
It was designed so each character had the corresponding number of angles to the number, so the number 1 has 1 angle, 2 has 2 angles, 3 has 3, 0 has none etc…
It is so obvious now, I’ve always assumed its one of those things that just is, with no logical explanation, but here it is, perfectly simple and satisfying

My jaw is legit on the floor right about now :D

This is WRONG. COMPLETELY WRONG. I’ve seen this post on my dash at least ten times with no correction so here it is:

This is the evolution of the modern numeral system. PLEASE STOP SPREADING MISINFORMATION. The history of Mathematics is awesome and amazing and Arabs made tons and tons of progress and invented many of the concepts we use today, but a numeral system based on angles IS NOT ONE OF THEM.

Old news, but amazing.  As a child, Christopher Becker of Queensland, Australia found this interesting piece of brass in a bag of pipe fittings in a shed on his father’s farm.  He’d been hanging onto it for 36 years before learning it was a horary quadrant dating back to 1396.  The story is here, and the auction listing has more information.

The numbers stamped into the quadrant are part of the reason I find this interesting.  4, 5, and 7 look very strange.  Arabic numerals were just starting to be used in Europe at this point, and their shapes were not yet standardized.

Gold foils of Pyrgi, VI century BC. National Etruscan Museum of “Villa Giulia”, Rome, Italy.
These foils are a valuable testimony of the alliance between the Etruscans and Carthaginians in the era of expansion of Carthage in the Mediterranean.
Two foils are written in the Etruscan language, one in the language of the Phoenicians: there is a dedication of a place sacred to the goddess “Astarte”, a goddess of the religion of the Phoenicians.
Pyrgi is the Latin name of the city founded by the Etruscans near the “Mountains of Tolfa”, in the region of “Lazio” , Italy.
