This clip takes us into the microscopic world through a series of steps, with each step being 10x smaller than the previous. It illustrates the microorganisms that exist in drop of water and the components of those organisms, including DNA and atoms.
This clip explores the origins of the universe and the focus of cosmologists. It describes the leading theory, the Big Bang theory, and discusses how physicists study the universe using particle colliders.
Bill Nye explains that an atom is composed of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus and have a positive and a neutral charge, respectively. Electrons, taking on a negative charge, move around the nucleus. Bill Nye demonstrates that an atom is mostly empty space by illustrating the distance between the nucleus and the electrons.
