Is That A Big Number?

If Time since first transatlantic wireless communication (123 y) was a standard unit ...

Time since the first modern humans (250,000 y)...more would be 2000 x Time since first transatlantic wireless communication

Time since first humans in Australia (50,000 y)...more would be 400 x Time since first transatlantic wireless communication

Time since the birth of Socrates (2,490 y)...more would be 20 x Time since first transatlantic wireless communication

Time since start of building of the Parthenon (2,468 y)...more would be 20 x Time since first transatlantic wireless communication

Time since the birth of al-Khwarizmi (1,246 y)...more would be 10 x Time since first transatlantic wireless communication

Time since the birth of al-Kindi (1,220 y)...more would be 10 x Time since first transatlantic wireless communication

Time since the birth of Toscanelli (627 y)...more would be 5 x Time since first transatlantic wireless communication

Time since birth of Sophie Germain (248 y)...more would be 2 x Time since first transatlantic wireless communication

Period of Pluto's orbit (248 y)...more would be 2 x Time since first transatlantic wireless communication

Time since the birth of Gauss (247 y)...more would be 2 x Time since first transatlantic wireless communication

Time since first human went into space (62 y)...more would be 1/2 of Time since first transatlantic wireless communication

One average human generation (25 y)...more would be 1/5 of Time since first transatlantic wireless communication
