WARNING: this page takes a longer time to load as each post contains videos in Youtube. Can't help that.

Susskind teaches at Stanford. I just found (after all the stuff below) a complete playlist of all his lectures, 136 vids IN ORDER, and unlike the sets below, these may be DOWNLOADABLE (my Youtube Downloader addin says 1st one is downloadable).

https://www.youtube.com/watch?v=pyX8kQ-JzHI&list=PLQrxduI9Pds1fm91Dmn8x1lo-O_kpZGk8


Else, these lectures are all over the place, and the ones below were assembled piecemeal on specific topic catgegories. For various bio summaries re Susskind, click here. Youtube allegedly lets you save a playlist but then I can't find it later. So I'm going to put the ones I find in this thread. The topics vary a lot, all within the rubric of quantum mechanics, relativity, or 'classical' Isaac Newton.

HOPEFULLY, they will just play all the vids in the playlist, in order. I can't see the sidebar Youtube used to provide with its embedded videos, for the playlist. So if it doesn't keep playing or you want to know the playlist, you'll have to click on the 'Youtube' icon at the bottom right of the player, and view it in Youtube. Sometimes the playlist disappears in Youtube, even though all these links ARE playlists made by the channel owners (like Stanford). Youtube is horrible about suddenly changing navigation, and is deaf to all complaints.

I'm thinking that you could copy and paste any one of these posts and either create a new thread of it for discussion, or just a new post. Cuz it's really hard to group these lectures in Youtube or elsewhere. So I found playlists of them, and do one set (usually 10) of lectures at a time, per post in THIS thread. So you can paste the post anywhere you like, the phpbb formats should be recognized anywhere.

Here's one whole set by Susskind Lectures (channel on Youtube, I don't know if it's Dr Susskind's own), re supersymmetry and Grand Unification. That means whether the physicist models are too cutely symmetrical (so false pic of the universe) or whether they actually point to the elusive 'Theory of Everything' aka Grand Unification, due TO their symmetry.

================

If you're wondering why I'm obsessed with physics, it's cuz I see a constant, continuing, expanding and extensive correlation to Bible verses every day; long ago I dubbed the correlation 'Divine Physics', before having time to really study the topic. So now, I am.

Made some really annoying videos about the idea 8 years ago, and put them in a much older webpage here, http://www.brainout.net/Fixes.htm . Good for insomnia, maybe.

Quantum Entanglement means two particles become instantly communicative and dependent on each other. So even if shot or otherwise separated by millions of miles, they always 'know' each other and when one changes, the other changes in an opposite manner such that the pair always balance to each other. China just shot two entangled particles (long after this lecture), and proved the idea true tho at only about 500 kilometers.

Implication is that there is some way to instantly communicate which is not dependent on the speed of light (duh, we know that from Bible, but physics is secular so it's slower to figure stuff out). Thus, for faster, more secure connectivity of devices and an exponential leap in computation power by our devices. So in the future you could call up your gramma on Pluto or Mars and be instantly able to hear her voice and see her face.

But we don't really know how it works, so can't be sure of enough implications. Videos cover what we know.

In physics, 'mechanics' simply means how nature's processes work, here with focus on planets, gravity, etc. The 'classic' means pre-Einstein, and goes back maybe 1000 years, but most notably starting with Newton.

https://www.youtube.com/watch?v=pyX8kQ-JzHI&list=PL189C0DCE90CB6D81


Classical Mechanics, in turn, is related to Statistical Mechanics:

Quantum mechanics, unlike classical OR Einstein, focuses on the idea of some universal underlying theory that explains atoms, too. Newton posited that they behave in some essentially-similar way to planets and other macro objects, but until the 1900s or so no one really tried to start the math, which heated up a lot after Einstein (who I think first published in 1905 or so). The shock was to discover that light is like 'raindrops' (Richard Feynman quip), but also yes still like waves (which Newton suspected). So what does that mean? Well, start here to find out. WARNING, a LOT of math is used, but it's at calculus level or below. Just listen while you do dishes, cuz every once in awhile Dr Susskind summarizes the meaning in words, no longer lots of variables you'd only recognize from being a math geek.

https://www.youtube.com/watch?v=JzhlfbWBuQ8&list=PL84C10A9CB1D13841


Here are the ADVANCED Quantum Mechanics lectures, but whoever made the playlist put the lectures in reverse order. So you have to start the playlist at the bottom, and then manually work back up top. So this one, is probably best played IN Youtube, as Susskind lectures always build on the previous class so you can't afford to skip.

Special Relativity was a discovery of Einstein (with others), and focuses on perceived differences in positions or rotations or other 'mechanics' due to the differences in the positions of the observers, given that the Earth is spherical. The shocking thing to come out of this later on, is General Relativity (next post), which essentially demonstrates that 'time' is part of 'space' and that the latter is 'curved' due to 'gravity', unlike Newton's model. The idea is to calculate the differences to find out the reality apart from one's relative positions.

Cosmology is supposed to be the big-picture diagram or explanation of the structure of the universe, with the grand whats and whys for it. Any religion has a cosmology too, so this is not like religion, but is based on conclusions from math, experimentation. But like religion it ends up being too 'accepted', so the big problem with 'scientific' cosmology is to keep being skeptical, knowing that what you think you know the answer is, it isn't. Feynman was Susskind's close friend, and Feynman in particular was, tho also a Nobel Prize physicist (who helped Oppenheimer work on the Manhattan Project) -- Feynman in particular wants us all to be continually skeptical of the pontification science like religion, gets into. You'll hear some of that same message in Susskind lectures...

Key foundational idea behind Cosmology and quantum mechanics, plus (upcoming) string theory, superstring theory, M-theory (the idea of multiple universes), and 'inflation' (how the universe expanded and will expand), is something called 'Theoretical Minimum'.

String theory posits a universal underlying 'theory of everything' which is still undergoing development. The physicists propounding it (and Susskind is one of the primary proponents), feel they've mostly 'solved' the 'everything' except for gravity (which doesn't seem related and they can't find particles for it), 'dark energy' and 'dark matter' (they can't account for how both came to exist); and, for the interactions within the nucleus of an atom. The basic idea is founded on quantum mechanics, which is basically that everything's composed of 'particles' which can be quantized (measured discretely) which aggregate via oscillation or wave action (which the 'particles' ride or drive or are attached to), thus forming 'strings' and hence the 'duality' of their acting like both waves and particles. The idea is to map out how these particle-waves join and separate to create everything in the universe, from the smallest starting atom to the grand spectrum of the universe with its planets and maybe.. alternate universes or mini-universes which co-exist right alongise or even within, ours.

The foundation of these ideas goes all the way back to Newton, who posited Light as a wave but also a particle. Scientists after him came to favor 'wave' until Einstein asserted also 'particle', and then with further study and experimentation in the 1900s, they came to understand that EVERYTHING is essentially the product of a wave action: light, sound, radio waves all being part of a single integrated system which by interaction CREATES matter in small and in great sizes over time.

The 'M' theory is a version of string theory which posits due to certain math findings in string theory, that these 'strings' are or create, 'dimensions' beyond what we can humanly detect: the number of 'dimensions' vary a lot, and Dr Susskind at the end of the videos below, briefly explains how you ferret out how many, but it's just basic intro.

These lectures are math-heavy. If your eyes glaze over with math, keep using 1Jn1:9 as you do some exercise or housework while you listen, cuz every five or 10 minutes, Dr Susskind summarizes the import of what he math'd out. I even sleep to these lectures, just to get familiar with the vocabulary (how you learned language and math as a kid, really).

Basic intro lectures which focus on concepts more than math, start at video 93-101 in my playlist (I might move them to other locations earlier in the list, and will edit this post if I do to the revised location):

https://www.youtube.com/watch?v=NZ-ElsvYKyo&index=93&list=PL559FEFBECB9CE9FA


The advanced lectures are in videos 62-71 in my Physics playlist:

https://www.youtube.com/watch?v=25haxRuZQUk&index=62&list=PL559FEFBECB9CE9FA


Updates for newer discoveries are in videos 102-111 in the playlist, but again are mostly conceptual, less math-heavy, and general, basic discussions:

https://www.youtube.com/watch?v=2eFvVzNF24g&list=PL559FEFBECB9CE9FA&index=102



As a result, there is now a 'Standard Model' of how these particles work, and its lectures run from video 112-121 in the playlist:
https://www.youtube.com/watch?v=Igl8hE3Eac0&list=PL559FEFBECB9CE9FA&index=112


For his explanation of the Gravity problem, click here.

As for the problem of dark energy and dark matter, a shorter video on that (see it in Youtube for related longer vids):

Most physicists still believe there was a Big Bang birthing 'our' universe. The idea was it happened and then RAPIDLY shot out waves and particles in an 'inflationary' explosion that spans 20 billion light years (presumed size of the universe), but happened 13.8 billion years ago. While trying to vet such claims, some physicists (here Susskind), posited that the calculations and laws of 'entropy' (decay, shrinkage, death, evaporation, etc) aren't calculated rightly, and that maybe instead the universe will undergo ETERNAL (unending) inflation, but will reconfigure in the process. One of the keys to this conclusion is the so-called 'arrow of time', a theory that time can only move forward (again due to entropy). So, starting at video 123 and running to 127, the foregoing ideas are math'd out.

He's adamant that Time can only go forward,

There are other videos in the playlist which you might find helpful. I'll be adding more videos as time passes. The Feynman lectures will be put in a separate topic within this 'Science' subforum. You might prefer to listen to him first, as he's a concept-explainer, but he talks faster than the Tokyo subway. He's dead now, and he and Dr Susskind were very close friends throughout their lives. Dr Susskind still lives and seems to still be teaching.

Sadly, his claim of 'curiosity' is really a prejudice, ASSuming that belief in God is ipse irrational. So he can't see how what he so splendidly teaches, actually conforms to what Bible says. Pray for him, cuz it's a tragedy for someone so enamored of physics, to be so negative but call himself objective and 'scientific', as soon as 'God' enters the equation. Never dawns on him that maybe God wanted to create all that math and laws to make an INDEPENDENT universe, etc.

https://www.youtube.com/watch?v=0p-Sqo83GX0


Even more sadly, this prejudice causes him to contradict himself and EXCLUDE from the 'Landscape' concept at the heart of physics, the POSSIBILITY of 'god' and hence 'consciousness' as something IMMATERIAL which is 'parented' by that God (Genesis 2:7, 1:26, etc). For you'll hear him vehemently contend that 'Landscape' is not merely the reality we see, but also the sum of ALL POSSIBILITIES, which of course is the core of quantum mechanics.

https://www.youtube.com/watch?v=WC8_rZdZtMs


Lies are believed when possibilities are not acceptable. Whether in a Trump voter or even a wonderful physicist. No one is immune. So use 1Jn1:9 like breathing.

I found this video on the perplexing nature of electron spin, and it makes me wonder if electron spin could be dictated by the ever changing quark activity found within the corresponding proton. If protons are constantly boiling with quark-antiquark pairs popping in and out randomly, then maybe that has an effect on electron spin. It would certainly have an effect on the proton's overall charge (and possibly mass), which could "irritate" the electron. Maybe some protons are more stable than others. If so, then maybe some electron shells are more stable that others, in terms of spin. Seems like this is a really big blind spot for QM.

There has to be a better explanation than assuming its a matter of probability...

Well, they say probability cuz they can't measure without disrupting the cycle into a new cycle, as it's subatomic observation, and we're made of atoms, too. Larger issue is that probability means immaterial, I'd argue, as the material reality doesn't exist until what CAN happen, DOES happen. So observation might intersect the immaterial plane(s) of potentials, making ONE a reality we observe, thus the other potentials can't be observed.
