Perhaps we have Dirac's choice of electrical engineering to thank? The Dirac delta can be thought of as the derivative of the Heaviside step function, which would have been familiar to those in electrical engineering in the 1920s.
Oddly when I tried to turn on subtitles it delivered them in Russian. And when I select auto translation to English I get the most bizarre nonsense. I think the video was simply uploaded with the metadata filled in wrongly.
Cool story about how you found the videos back, thanks for posting! So "mundane" a process, but you made contribution to important historical recordings. Good use some clean-up, perhaps with some nice AI based filters?
11:19 you cannot observe a 1-state because it does not 'exist'. If there is no change, there is no time, if there is no time there is no existence. So ... the 1-state does not exist (in time), only the *change* from state 1 to state 2 exists (because change=time) ... so, state 1 'has to' change (to create time) and this change can be observed Maybe Heisenberg didn't realize the why, but he did notice that only the 2-state could be observed👍
The actions of this cameraman are unforgivable. Look at the quality Hitchcock got and millions of others at that time. My father's super 8 in the 50's was way better than that. Not only did he do that on one reel he did it over numerous days with more than enough time to correct his imbecilic level of camera work.
This connection between introducing a non-integrable phase shift field into the quantum wave function and the electromagnetic field has always struck me as borderline miraculous. The whole business of gauge theories seems almost like a "gift" from the universe. It's just marvelous living in an age when with a few clicks of some buttons I can partake of the output of these great minds like this.
"the person who originates a new idea is really not in the best position to follow it up, because he's so scared that something will turn up which will knock the whole idea on the head."
In 1975 as a stage II student of Physics, Astronomy and Astrophysics etc., I did of course attend these lectures. These grainy TV images bring back memories of that era. I often wondered what became of some of my lecturers, such as Ken Fea and Noel Doughty. Eventually there were actually moments when it was possible to ask what Dirac meant on some esoteric reference; the poor man, however ancient, was still way ahead of the rest of us, and somewhat bemused that we could not all keep up.
I had to smile at 19:30 when Mr Dirac started describing how he needed to find references for his Hamiltonian ideas and had to wait after his Sunday walk until the libraries opened on Monday - but perhaps not having Google meant he had to use his brain more than his fingers on a keyboard...
Heinrich Kluver at the University of Chicago resided in Culver Hall with a biology library on the floor above his. He had 24 hour access to this library, When I went to UofC in the 1950's each department had its own small specialty library, many with with a lot of extremely specialized books contributed by retiring professors. The specialized physics in the Fermi building even had a librarian who could translate math and physics books from Russian and German into English. This library was open 24 hours to relevant physics staff. Unfortunately since then these departmental libraries were discontinued and their volumes buried into the vast graveyard of knowledge called the Regenstein library. There is no way these libraries where one could freely browse books related to your interest can possibly compare to relatively dead megalibraries.
I have recommended these lectures to foreign colleagues but they had great trouble trying to follow them and soon gave up. Could you supply subtitles for non-native English speakers? If not a transcript would be welcome.
They can't. Magnetic fields arise from moving charge and poles are defined by the direction of flow. But you probably already know that. Sorry, but this nonsensical search by supposed geniuses drives me mad.
Great lecture, but Quantum probability still rules, the Universe is indeterministic and uncertain and only the consciousness will determine and make certain by the choice of the free will my friend Dirac.
A theory capable to explain the connection between the gravity (relativistic theory) And the electromagnetic theory witch depend obviously on the formulation of each other both in laws and measures is essential to describe the whole spectrum of the elements and to describe cosmology and unifies Them A science amateur
