how eratosthenes figured out that the earth is round in 240 B.C and came up with the size of earth's circumference. without a calculator.
Parsival
says
read somewhere how it was done but I can't quote you the book. Hope you find it. Geo+meter=earth measure=geometry.
shyong
thinks
its freaking amazing. and people used to be burnt at the stake for thinking otherwise. all because of religion. the dark ages. sigh.
sweetestsmiles
says
if i am not wrong, he knows the distance from city A to city B and knowing the sun at noon is
sweetestsmiles
says
@ uses some trig and able to work out the distance.
Parsival
says
no, that's just Europe and their scary genes. The rest of the world's fine
Parsival
says
smiles, every pr 6 kid knows how to do that. it's the earth's circumference that's a neat trick to do.
sweetestsmiles
says
agrees, no one knows the value of pi at that time.
Parsival
says
didn't they work with 22/7?
sweetestsmiles
says
thus the value of earth circumference is not accurate.

poeple needed to be smarter back then. Now got google.

wonders
why people trust wiki...?
kittystar69
thinks
because he has too much time... and because back then there was plurk...so he could spend all his time figuring this one
shyong
says
excuse me. we are taking about nearly 2050 years ago, some chap in toga worked out the circumference of earth.
shyong
says
its a power papa there man. without even leaving the earth. and using soil and sticks. well done man.
shyong
says
respect.
yeah... maybe he got help from aliens...u know, E.T.
shyong
