I thank you, Skye and your kind hooman assistants, for the attempted #edification.

I'll keep reading physics, but I don't think I'll make much progress on this sort of stuff. "I'm trying to think who the third person could be", indeed.

#BrainMelt #Eddington #Einstein #Dirac

Born #onthisday in 1902, Paul Dirac was an English theoretical physicist who is regarded as one of the most significant physicists of the 20th century. He was the Lucasian Professor of Mathematics at the University of Cambridge, a professor of physics at Florida State University and the University of Miami, and a 1933 Nobel Prize recipient.

Dirac made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics. Among other discoveries, he formulated the Dirac equation which describes the behavior of fermions and predicted the existence of antimatter. Dirac shared the 1933 Nobel Prize in Physics with Erwin Schrödinger "for the discovery of new productive forms of atomic theory". He also made significant contributions to the reconciliation of general relativity with quantum mechanics.

Dirac also invented the "Dirac notation" (aka bra-ket notation), which is very handy for all sorts of computations (especially in quantum mechanics) and among many other things studied what today we call the Dirac Delta Function. See, for example,

or the images. As always, questions/comments/corrections/* greatly appreciated.

Not all mathematicians seem to like the #Dirac #notation used in #quantum #physics 🤔

How about some (theoretical) reality?

#Dirac, #Feynman and what to put in the #PathIntegral.

Very interesting and not too hard to follow.

What do you think is the best #action or #scifi #movie in terms of #audio effects?

I think I have something messed up in my #DolbyAtmos setup and need #help testing it out.

#DiRAC Live calibration made with 2 points.

My setup: #Onkyo TX-RZ50 receiver; #Focal Chora 826-D towers with upward firing speaker, 806 in the back (yes, overkill and I love it) and the huge central speaker. For subwoofer I brought the #RSLSpeaker Speedwoofer 10S that I had purchased in the US.

In #quantum theory use is made of compositions
𝛿(F(x))
of the #Dirac delta function with other functions. Prop. A simplifies this to facilitate computations, and Prop. B is my exploring what happens with higher order zeros. N.B., here we're doing #calculus the #Physics way!

Nothing can beat learning quantum physics from one of its greatest masters. The mathematical elegance of Paul Dirac's proofs and explanations truly boggles the mind.

OggConvert was last released in 2010.

It was a Linux program written in Python and GTK and used the GStreamer framework to convert digital audio and video files into Vorbis, Theora, VP8 and Dirac. It supported outputing audio and video into OGG, Matroska and WebM containers.

If you are looking for a modern transcoder than you take a look at HandBrake.

In addition to his award-winning work in #physics, he is also remembered for a scale he devised to rank 20th-century physicists. It was an exponential scale, according to which 0 was the highest possible (indeed infinite) score, followed by 1 through 5, and because the scale was logarithmic, a “1” was considered 10 times more productive than a “2”, and a “2” ten times better than a “3”. #Newton was a “1”, as were Niels #Bohr and Paul #Dirac and several others. #Einstein was given the highest rank, a “0.5”, which made him about three times smarter, or at least more productive, than Newton and Bohr. #Landau initially ranked himself as a “2.5”, but later decided that he really deserved to be a “2” and moved himself up the scale.
