Up to 40% of PhD students suffer or risk suffering mental illnesses. The hunger-games-like competition model of academia is an important reason for this. Being well informed before joining a group or lab for the PhD can make huge difference @LabVisor_site https://t.co/0mveqvqV98

Today, we have a new, modern definition of the kilogram, and a few other spiffed up units to boot. But maintaining a system of units is an unending task: Soon we might need to redefine seconds. https://t.co/qMkggx7fB6

๐Place a particle in a box
๐At low E (n=1), the particle acts "strange" (i.e. most likely to be found at the center)
๐As E โ๏ธ (nโโ), ฯ(x,t) oscillates faster and "peaks" grow closer

In Classical Mechanics, the state of the system is completely determined by its position and momentum (๐ฑ(๐ก),๐ฉ(t)).

๐The free particle is actually a propagating "wave packet" that spreads out over time
๐This spread corresponds to uncertainty in position
