Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron, and electron - come together in trillions of combinations to form ... everything.
A unit is a frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units.
Today's Crash Course Chemistry takes a historical perspective on the creation of science, which didn't really exist until a super-smart, super-wealthy Frenchman put the puzzle pieces together - Hank tells the story of how we went from alchemists to chemists.
Hank gives us a tour of the most important table ever - The periodic table of elements, including the life story of the obsessive man who championed it, Dmitri Mendeleev.
Hank brings us the story of the electron and describes how reality is a kind of music, discussing electron shells and orbitals, electron configurations, ionization and electron affinities, and how all these things can be understood via the periodic table.
Chemists need stoichiometry to make the scale of chemistry more understandable - Hank is here to explain why and to teach us how to use it.
