Explorit Science Challenge #26

Question #1 - The continuous emission of radiation energy from certain substances (such as radium) appears to contradict the widely accepted theory that energy cannot be created or destroyed.

Which modern physicist explained, in a special theory, that small amounts of matter in the nucleus of certain atoms are continually being converted to energy with a consequent decrease in the mass of radioactive atomic nuclei?

Answer

Question #2 - British scientist Michael Faraday (1791-1867) made some fundamental discoveries about magnetism and electricity that ultimately made it possible for the following words to be heard in living rooms around the world: "That's one small step for a man, one giant leap for mankind"

What is the name of the American who spoke those words and where was he when he spoke them in 1969?
