Yeah seriously 😂 it’s wild… we’ve got satellites, space photos, GPS… and somehow we’re still debating something people figured out with shadows and basic math. Feels like we went forward ...
It's true. On the other hand, earth roundness is something that is not that easy to prove to yourself from first principles. How many of us have actually done the stick shadow experiment?
This could actually be a great classroom exercise: connect with various schools at the same longitude as yours, but different latitudes. Meet on Zoom at noon, and everyone measures the shadow of a vertical stick on live cam; then notes are compared.
