Joshua, age 7, Shoreview, Minnesota Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of scientific information to future ...

The question of where atoms come from requires a lot of physics to be answered completely – and even then, physicists only have good guesses to explain how some atoms are formed.

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

The negative charges or electrons separate to the bottom of the thunderstorm, positive to the top. As these electrons zigzag down, known as a "stepped leader", it draws up a positive charge from ...
