16 March 2016- Sublimation | PWN Physics 365

On this day in physics: 16 March 1789- Happy Birthday to Georg Simon Ohm, who would have turned 227 today. Ohm is the namesake of our unit of resistance, the Ohm, and is the physical opposite of the inverse of the ohm, the Mho. Ohm continued the work of Alessandro Volta and his work with electrochemical cells.

Word of the Day- Sublimation is a process where a solid changes immediately to the gaseous state without entering the intermediate liquid state. Sublimation occurs when temperatures change that cause a solid to exist, to temperatures which cause a gas to exist. At certain pressures (which are lower than a substance's "triple point"), it is not possible to have that substance exist in a liquid state.

Quote of the Day: "Resistance is Futile" -Georg Ohm (I was cruising for quotes and I came across this joke quote, which I thought was too good not to share here)
