Physics/Biophysics 2018 ACCHS Professor Spears Sarah Donnelly TCM & Physics Of all the fascinating material covered in this course, it was quantum physics which really stuck with me. The impossibly small world which underlies our macro world is governed by different laws, because when things get very small, apparently they also get very weird. The laws which rule the quantum level can't be applied to the world on our scale, and vice versa. It would like assuming breathing air would be like breathing water. The different worlds just work in different ways. Some favorite weirdnesses: • Entangled particles, separated by the globe, will simultaneously react even if only one particle is subjected to a stimuli. • Molecules can exist in more than one physical state at the same time, temporarily stopping at one particular state when being observed. Is it a wave? Particle? Depends on who's watching and what their expectations are •
