Discovery School - 100 Greatest Discoveries - Physics
1. The Law of Falling Bodies (1604) Galileo Galilei overturns nearly 2,000 years of Aristotelian belief that heavier bodies fall faster than lighter ones by proving that all bodies fall at the same rate.
2. Universal Gravitation (1666) Isaac Newton comes to the conclusion that all objects in the universe, from apples to planets, exert gravitational attraction on each other.
Discovery School - 100 Greatest Discoveries - Earth Science
1. Earth's Core (1906) Seismologist Richard Oldham determines that earthquake waves move through the central part of the Earth much slower than through the mantle around it. He surmises that the Earth has a core composed of liquid.
2. Earth's Inner Core (1930s) In 1936, Inge Lehmann documents that some seismic waves from deep inside the Earth's core do not pass through, but are reflected back. It becomes clear that the Earth has an inner core consisting of a small, solid iron sphere that is surrounded by a thick outer core composed of liquid iron.
