Mike Tuke – Determining the shape, size and internal structure of the Earth
9 February @ 7:00 pm - 9:00 pm
A talk to demonstrate
- how 2000 years ago the Greeks knew the Earth was a sphere and could calculate its circumference;
- how the speed of rotation affexts the direction of wind and ocean currents and why the ice ages altered the spin;
- How to measure the density of some rocks and compare with the density of the whole Earth;
- What that information, along with data about earthquakes tells us about the internal composition of the Earth;
