On this day in physics: 14 March 2015- We celebrated super pi day, or 3-14-15. March fourteenth usually describes the first three numbers in pi, 3.14, but last year we celebrated the pi day which describes pi to five decimal places, 3.1415, which only occurs once every hundred years!

Word of the Day- Verschränkung is the German word first used by Erwin Schrodinger to describe the idea of quantum entanglement. Entangled particles are two particles whose states only occur once measured. If a decay happens and two particles are emitted, their combined spins must add to zero, so if one is measured to have spin of -1/2, the other MUST immediately have a spin of 1/2. Verschränkung describing entanglement was first used in the description of the Schrodinger Cat thought experiment featured as yesterday's word of the day.

Quote of the Day: "Quantum physics thus reveals a basic oneness with the universe.” -Erwin Schrodinger
