An atlas of firsts

Where and when was it invented?
Drop a pin, pick a year, score up to 1000 a round.

How scoring works

Each round is worth up to 500 for where and 500 for when.

Where: full marks within 25 km of the spot, half marks about 600 km away, close to nothing past 5,000 km.

When: the tolerance grows with age. Being 5 years off on the first email costs as much as being 200 years off on the first writing.
