Foe

In prepping for my lecture tomorrow, I learned a new term, the foe.

A foe is a unit of energy equal to 10^44 joules or 10^51 ergs, used to measure the large amount of energy produced by a supernova.[1]

The word is an acronym derived from the phrase [ten to the power] fifty-one ergs.[2] It was coined by Gerald Brown of Stony Brook University in his work with Hans Bethe, because "it came up often enough in our work".[3]

This unit of measure is convenient because a supernova typically releases about one foe of observable energy in a very short period (which can be measured in seconds). In comparison, if the Sun had its current luminosity throughout its entire lifetime, it would produce 3.827×10^26 W × 10^10 years ≈ 1.2 foe.


Jesus' shitballs!

The equivalent energy outburst as when I lite one of my farts after a night of Guiness, Cosmopolitons, Champagne Kirs and a Sambuka -Hic!
