6:51Physics, Space & Chemistry
Physical explanations connect observations to models that can be tested. Here you can explore physics, astronomy, chemistry and space exploration, from introductory demonstrations to technical talks. The topic links help separate a first explanation of a concept from a closer look at an experiment, instrument or mission.
