Here’s something to think about as you kick off 2025: We are all stardust. Every atom of oxygen in our lungs, of carbon in our muscles, of calcium in our bones, of iron in our blood—was created inside a star before Earth was born. Hydrogen and helium, the lightest elements, were produced in the Big Bang. Almost all of the other, heavier, elements were produced inside stars. Stars forge heavy elements by fusion in their cores. In a star of intermediate mass, these elements can mix into the star’s atmosphere and be spread into space through stellar winds.

“I always remember having this fight with a random dude who claimed that ‘straight white men’ were the only true innovators. His prime example for this was the computer… the computer… THE COMPUTER!!! THE COM-PU-TER!!!
Alan Turing - Gay man and ‘father of computing’ Wren operating Bombe - The code cracking computers of the 2nd world war were entirely run by women Katherine Johnson - African American NASA mathematician and ‘Human computer’ Ada Lovelace - arguably the 1st computer programmer”

Also Margaret Hamilton - NASA computer scientist who put the first man on the moon - an as-yet-unmatched feet of software engineering, here pictured beside the full source of that computer programme. #myhero
