Why has technology accelerated so much in the last 100 years?
when you consider the atom was only thought about approx 100 years ago but now we have nuclear technology.
Same with flying, the Wright brothers flew a few feet a hundred years ago now we can put craft on Mars.
Everything seems to advance so quickly now.
Once countries and goverments became so rich they were able to throw money into projects like the V1 and V2 rockets Germany had during WW2, then the space race, computer development, then things like CERN and the Hadron Collider.
CERN required many countries to combine their money into this huge expensive project, something no single country could probably afford.
