For our next free public science lecture, the Mystery Science Salon and the Edmonton Round Earth Society
present guest speaker Michael J Johnson's talk «How the Heck Did They Know the Earth was Round?» at The Aviary
on August 11.
Long before satellites, airplanes, and telescopes, humans knew that the Earth was a sphere. But how? Together we'll stumble over Greek names and explore the logic and observations used over two thousand year ago that turned our flat world round.
Doors at 1, talk from 1:30-2:30 followed by a Q&A.
