Doodle Science - October 2015

Circulated to schools, organisations and individuals - covering primary science and related bits and bobs.

A Jacquard Loom. These are often regarded as the first programmable computers, the bit of card at the top has holes punched in it and can be changed to change the pattern, I found this excellent machine is the Bradford Industrial Museum when I was taking time off from the BSA's science festival in Bradford. The thing is, I noticed there were other looms with chains of wooden blocks with holes and pegs in them, to change the program there you move the pegs.
