The discovery of phosphine on Venus, in 2017, sparked significant scientific debate and renewed interest in the planet’s atmospheric composition.
The presence of phosphine gas in the atmosphere of Venus has been a subject of intense scientific interest and speculation since the late 20th century. Initially, Venus was considered a hostile environment with extreme temperatures and pressures that seemed incompatible with potential biosignatures.
Pi Day (March 14) was celebrated for the first time in 1988 by American physicist Larry Shaw.
Pi (often represented by the lower-case Greek letter π), one of the most well-known mathematical constants, is the ratio of a circle’s circumference to its diameter. For any circle, the distance around the edge is a little more than three times the distance across. Typing π into a calculator and pressing ENTER will yield the result 3.141592654, not because this value is exact, but because a calculator’s display is often limited to 10 digits.
