Physics
Physics is the study of matter and its motion through space and time. This natural science describes our whole Universe, from subatomic particles to distant stars, and everything in-between. Physicists such as Albert Einstein, Fields Bohr, Isaac Newton, James Clerk Maxwell and Marie Curie are among the great scientists to have contributed to our ever growing understanding of the classical and quantum world. Physics investigates a wide range of subjects such as: forces, astronomy, energy, atomic structure, mechanics, waves and particles to name a few.
