This symbol is known as e-constant or Euler’s constant. Also, e-symbol in Maths which holds the value e 2.718281828. In Mathematics, pi symbol is also referred to as Archimedes constant.

The pi symbol is a mathematical constant which is defined as the ratio of circumference of a circle to its diameter.
Mother Jones was founded as a nonprofit in 1976 because we knew corporations and billionaires wouldn't fund the type of hard-hitting journalism we set out to do. We are talking here solely about the pronunciation of Ψ in its quantum mechanical sense.īy signing up, you agree to our privacy policy and terms of use, and to receive messages from Mother Jones and our partners. ☪nd you don’t pronounce the initial P if you’re using psi as short for psionic. Don’t me with your eigenvalues and inner products. Is Ψ usually pronounced with its initial P? If so, how distinct is it? So I guess this is a question for physicists, or anyone who’s taken a quantum physics course. The best I can describe it is that it sounded as if the P was trailing off before it even got started, followed by a normal pronunciation of sigh. However, on one particular site the speaker was clearly pronouncing it p-sigh, but with just the barest emphasis on the P. It never occured to me that you’d pronounce the initial P.² So I googled around a bit and got conflicting answers, which I suppose is very on-brand. I’ve always pronounced it sigh, rhymes with pie. The easiest way to find out I guess is to listen to the video? I have no idea which one is the “correct” pronunciation, given that it’s Greek and I don’t speak Greek, but I can tell you that if you pronounce it this way physicists will know what you are talking about. Well, I pronounce it the way that I have heard it most often which in English is “ps-ai” (in German it would be “ps-ee”). How should Psi be pronounced? Is it P-Si, Si, or a superposition of the two? Or is the word not pronounceable until it is spoken, like when Prince changed his name.īut Hossenfelder took the question seriously:
As you may know, the quantum wave function is represented by the Greek letter psi (Ψ), with |Ψ²| representing the probability of a particle being found in any particular place.¹ So a reader decided to try on a joke in comments: But then the subject turned to linguistics and it got interesting.
