Episode 52: The Quantum Mechanical Universe - The Mechanical Universe 

After a month of dedicated watching I can’t believe I’m one episode away from finishing the most underrated films ever.🤧 It’s been a privilege CalTech

RIP Dr. Goodstein. You left us pure gold! I love watching these episodes over and over again.

Watched some of this series in AP Physics in 88-89. One of the best courses I ever took. Just finished the whole series on RU-vid. It's enlightening, entertaining, and even poetic at times. A remarkable production.

Just finished..... Fabulous production. Hard to believe it is nearly 40 years old.

I have listened to all the 52 episodes of this interesting and useful lecture series. Thanks to Caltech. I have gone through other lecture seiries from online courses and other sources. But this one gives a complete coverage of introductory physics at the college level. Both the historical and conceptual developments in Physics are very clearly given.

I loved watching these in the late 80's. As a graphics designer and fascinated by science, I love the visuals that so well explain the concepts. Congrats to Dr. Jim Blinn, who did the animations, a pioneer in CGI. I briefly met him at Siggraph 2000.

I loved this series when I was a kid. still do!! Glad it’s finally been posted!!

Thank you Caltech, we are ready for Sean Carroll to pick up where this leaves off!

A wonderful series that deserve respect.

The animations at 18:26 were what really solidified the nature of the Heinsenberg uncertainty principle for me; haven't heard a better example of that since.

It was heartening to hear newtonian universe is gone out of the scientific minds but at the same time quantum mechanical universe has given rise to the entirely new way of observing at the universe! It was a wonderful journey with the series. Cant thank enough for making the lectures public💐🙏🏻👏👏👏👍

Cant believe i finished it. Im so glad something like this exists. I try to push myself through textbooks and lectures, which i do, but even though i try so hard its very hard to pay attention for me. I think? The visuals keep me interested, and the history gives context which helps me care about the discoveries. Truly an amazing production, i hope ill be smart enough someday to understand all of this and more.

Love Goodstein's precise enunciation and presentation. The core video presentation is also very good. Thankfully there are specialists who can describe what complex equations tell us and a rational mind can use this to form understanding and move forward. Michael Faraday had poor maths understanding, but Maxwell put his finding into beautiful equations for us to use as tools in practical man's Newtonian world. Scientists can continue with quantum mechanics and general relativity, trying to understand ultimate reality in the universe. I am not optimistic about absolute knowledge. Sadly, tribalism may end the quest with nuclear war and the end of time for mammals like us.

Having recently listened to Freeman Dyson's views on a grand unified theory as chasing rainbows I am happy to announce (to my computer) I feel better. Tying gravity and classical physics to quantum mechanics is un necessary. Each can exist on it's own and Newton and Einstein remain kings.

for those who had the great fortune of having this series in your learning years you will never know how lucky you are.

This is lovely amazing fabulous

Finally I watched. Probably I spent more than one year with some breakes, but anyway thank you a lot! Really amazing series. Probably I will see it again later.

I found this lecture series when I was looking for "Ether" on RU-vid, while I was reading "A Brief History of Time". Michelson Morley Experiment lecture forced me to watch the complete series. I watched it from 1-52 probably within one month. Though I'm a biological student, it addicted me. Thank you so much, Dr.David and CALTECH team for this amazing production. Can't believe it produced in 1987 :)

I just finished this wonderful series! Thank you Dr.Goodstein. Thank you Caltech!

Very very good series.

[ 2:23 ] We're still so close. Just give it another four decades.

I can't help notice that this video series doesn't mention Lagrangian Analytic Mechanics . . . and then Hamiltonian mechanics. Lagrange, and really Leonard Euler as well, were able to derive and unify the findings of Galileo and Newton as min/max stationary points of differential equations. Lagrange had been able to do physics without any diagrams(I'm not to sure the absolute value of that actually; seems to me that geometry is like diagrammatic for setting up algebra equations). This all led to Emmy Noether's theorem about symmetry and conservation principles, which is at the basis of unification physics past basic Quantum Mechanics.

Professor is very interesting about the way inroducing subject

Thermodynamics also had a role in the quantum hypothesis. While working on kinetic gas theory Ludwig Boltzmann had to introduce quantization of the energy of individual gas molecules because otherwise the entropy would have an infinite value.

It got emotional at the end

Download the video. Open in, say, VLC Media Player, right-click "Tools", select "Track Synchronization", apply a (16.200 second) "delayed" to the audio to make up for the "Annenberg Media" lead-in that was ignorantly added over the sound track at the beginning. Fixed. Thanks a lot and,...,you're welcome.

Nice clear series. Goldstein is currently 80 years old. Talk about time contraction. Where did the years go?

Wonder where are these students now?

The time has come the teacher said, to tie up many threads...

@ 27:08 someone threw something at the back. 😂

Euler's e-Pi-i sync-duration positioning is the mechanism of universal coherence-cohesion quantization. 1-0-infinity instantaneous trancendental =motion potential of logarithmic superposition-condensation. Singularity-point Entanglement Fusion-Fission resonance bonding all-ways all-at-once proportioning is Math-Phys-Chem and Geometrical phase-locked coherence-cohesion holographic time-timing presence of probabilistic sync-duration. Corpuscular convergence on log-antilog interference positioning-location to Fluxion-Integral divergence instantaneously, the entangled property of ""impossible" potential 1-0-infinity pure-math axial-tangential orthogonality freeze-framing Actuality .., and so on. Finding correlations is the imagined fun of Sciencing Re-search Actuality. (But no body gets to keep the credit for this Eternity-now Interval Conception Superposition-point Singularity Perspective)

Wonderful series of videos. Those kids are well into their careers and are making contributions in their own way to the “revolution” and these videos are setting many others on their way for the next generation. Thanks to CalTech. Thank you.

Page 12:00 Albert Abraham Michelson the Nobel price recipient. M&M misunderstood both light wave and Aether enough to committed design and conduct experiments ending with a false negative results - as expected. All electromagnetic and light wave requires a medium (dielectric) to propagate, a medium order of, either (1) e0 of vacuum in Maxwell’s equation, (2) gas, (3) water or (4) glass. It should be noted that higher order dictates how light behave, which M&M over looked. So the instance we let air infiltrate the interferometer then air becomes the medium under test and not Aether. Same is true if interferometer was built submerged in water, then water is the medium under test and not Aether. Aether exists in absolute empty space with a measurable dielectric constant e0 of 8.8541817128 pF/meter. At this point of writing, Aether’s properties still not fully understood. Can we just insert a vacuum hollow cylinder along each 90-deg arms and call it Aether compliance? No because Aether moves as much as the cylinder moves. Otherwise the whole experiment must be conducted in outer space far from galaxy, spiral arm, molecular clouds or cosmic plasma networks just to enable the result to be better conclusive. Besides that Aether is a dielectric medium that is easily dragged along with the interferometer in outer space. Detecting Aether correctly is a daunting task beyond the resource of M&M at the time. All we can conclude at this point is that both M&M ran their experiments with air and not in Aether.

the answer is.......... 42

Congratulations students. Now make lots of money because you will not be able to fix anything for yourself in real life
