#Magnetism is the best science #####by @katemonkeys for @indutny
Magnetism is by far (a) the coolest and (b) the most educational quantum mechanical phenomenon. It’s fabulous because it is both deep science and actual real-world applications you use every single day (computer hard drive, anyone?). Finally, it can be understood on a crazy range of length and timescales: ridiculous magnets in the National High Magnetic Field Lab that are so strong they implode on themselves, blocks that move themselves, single atoms with localized moments that have to be understood by extrapolating their single particle wave functions, whatever. I contend that learning about magnetism will give you an awesome window on the rest of QM.
##My absolute favorite books on the subject:
Magnetic Materials by Nicola Spaldin Eminently readable but still has homework-style problems in each chapter if you want.
Nanoscale magnetic materials and Applications by Oliver Gutfleisch et al Pro: Also pretty readable and way more in-depth. Con: Like five times as long.
Modern Magnetic Materials: Principles and Applications by Bob O’Handley Super readable, written by an amazing physicist who later became more of a technologist. Con: pretty much a doorstop.
