@@Kathy_Loves_Physics Quantum Entangled Twisted Tubules: When we draw a sine wave on a blackboard, we are representing spatial curvature. Does a photon transfer spatial curvature from one location to another? Wrap a piece of wire around a pencil and it can produce a 3D coil of wire, much like a spring. When viewed from the side it can look like a two-dimensional sine wave. You could coil the wire with either a right-hand twist, or with a left-hand twist. Could Planck's Constant be proportional to the twist cycles. A photon with a higher frequency has more energy. (More spatial curvature). What if gluons are actually made up of these twisted tubes which become entangled with other tubes to produce quarks. (In the same way twisted electrical extension cords can become entangled.) Therefore, the gluons are actually a part of the quarks. Mesons are made up of two entangled tubes (Quarks/Gluons), while protons and neutrons would be made up of three entangled tubes. (Quarks/Gluons) The "Color Force" would be related to the XYZ coordinates (orientation) of entanglement. "Asymptotic Freedom", and "flux tubes" make sense based on this concept. Neutrinos would be made up of a twisted torus (like a twisted donut) within this model. Gravity is a result of a very small curvature imbalance within atoms. (This is why the force of gravity is so small.) Instead of attempting to explain matter as "particles", this concept attempts to explain matter more in the manner of our current understanding of the space-time curvature of gravity. If an electron has qualities of both a particle and a wave, it cannot be either one. It must be something else. It must be something else. Therefore, a "particle" is actually a structure which stores spatial curvature. Can an electron-positron pair (which are made up of opposite directions of twist) annihilate each other by unwinding into each other producing Gamma Ray photons.
It is remarkable how Planck, being an old school physicist, went against his own ideology and stood by the facts. This is pure integrity of character that you find in Planck and Einstein, both didn't liked what they found out but kept to the model that was more adequate to the experiments.
You might also add to that list the great Kepler, who realised that he had to abandon his cherished theory of the heavenly spheres when the observational data simply did not support it.
I wish Physics professors were more like you Kathy. For me it''s not just about the theory and the math but the history around the motivation and the how things were discovered that makes the whole thing interesting. Please keep up the great work!
I'm a retired engineer so I took the Physics series of classes in college, but these videos sure expand on and include some great historical perspective to the subject. Thanks!
I just discovered your channel and I like it very much. The blend of physics and history is so important. Ideas don't just appear from nowhere. Keep it up.
Love your videos Kathy :) I'm an EE by trade but I love watching these so I can reaffirm my understanding of electricity, and learn some more history that wasn't taught to me in school.

Great video!, I actually found a coin when maybe 23 years ago in the dirt one day turns out it is an old Prussian coin with Max Planck on one side and the Prussian eagle on the other, I was going through some old stuff and it led me to this video I've done my own research into quantum mechanics and I had no idea I had a coin with Max Planck on it for all these years
Nice explanations. Thanks for putting patreon plug at end. Many others put in beginning before viewers have chance to assess if even like, wasting time. If there is interest it is peaked toward the end if done well and more receptive timing.
I really love your channel. I hope a lot more ppl will watch this, as it is both history and science which gives a better feel of how the science and ideas evolved and how they were related. This channel deserves multi million subscribers! On to the next video!!!
"Planck’s Route to the Black Body Radiation Formula and Quantization" by Michael Fowler details Planck's thermodynamic analysis of the entropy of Blackbody Radiation, which motivated his hypothesis to satisfy Wien's Law at high frequencies. Planck's application of Boltzmann's Statistical Mechanics led to his conclusion that the material of the walls emit and absorb radiation in discrete quanta. It's a great read.
Kathy, I just love your personality and how it comes through. Your videos feel more like a friend explaining to me rather than a teacher lecturing. Far more compelling. And hats off to you for the way you tease the next episode. You do a great job of leaving me wanting more.
soccerguyhammers I wish more physics was taught from a historical viewpoint. To me it is more interesting and makes more sense than presenting physics in a step by step mathematical point of view. Although both viewpoints are helpful in truly understanding the subject.
I am still aghast. Plank wrote Boltzmann’s equation. It will take days to accept this. And as always, your voice is perfectly suited for the history of science. Pure fun.
Fascinating video, and I'm now going to watch your other ones. One comment though: Wien is not pronounced like vine in English, but as veen (the same German pronunciation as Wien the capital of Austria).
OMG in one sentence you corrected a major misunderstanding of mine about black body radiation. I'm so glad I watched this video. Have to watch the video about Kirchhoff right now
Pronunciation note: Wien is pronounced /vi:n/ (or "ween" trying to imitate English phonetic spelling). More generally, for German names 'ie' is pronounced /i:/; it's the order 'ei' that for historical reason or another seems to be commonly well-known by English-speakers (to my amazement) such as in Einstein, pronounced /ainʃtain/, although the German way of pronouncing the st-cluster has been widely dropped by English-speakers. Great video. :)
Joonas Mäkinen thanks for trying to help me - German pronunciation is particularly difficult for me for some weird reason. Luckily, I’m done with Wien (I think) but there are many more to butcher. Kathy
Wow, another language geek like myself! Nice comment but you meant to write "veen" instead of "ween" up there, so consider your own self to be corrected, politely of course. Also, the cluster "sp" in German is pronounced "shp," Max Planck is "Mox Plonk" and Maxwell's middle name is pronounced "Clark" - and that's supposed to be English, the Scottish version anyway.
"Veen", "wean" or "vien" (rather than "ween") would be a more obvious English phonetic equivalent to the German „Wien“. The Germans pronounce their and the same way as native Anglophones pronounce their , but Anglos would pronounce the word "west" differently from "vest" -- and would tend to hear the difference in such pronunciation. Not only that, but if left without contextual correction, the difference in pronunciation would account for a difference in meaning -- at least in English. Nothing of the like exists between the German "wagen" and "vagen", which are phonetically identical to each other. Thus, for English but not for German, the difference between /v/ and /w/ is said to be significant to a "phonemic" extent, beyond mere "allophonic" variation.
I highly appreciate this lucid presentation on the birth of quantum mechanics. It was a historic moment that happened on 14th December 1900. A day to be celebrated.
I really adore your channel. Bit of a random thought, but I'd love to see you explore an offhanded comment mentioned in this video regarding Planck's rejection of the atomic theory Boltzmann's statistical approach was based upon. Many know the tale of the atom arising from the ancient writing of Democritus, but less known is how it reemerged in modern thinking, and why it would be regarded as controversial by somebody like Planck so close to the 20th century (what with it being seen as self evident these days). What I know of it is contained in this tiny passage in a book I'm reading called The Darkening Age, by Catherine Nixey, and simply reads: " Democritus’ atomic theory did, however, come down to us - but on a very slender thread: it was contained in one single volume of Lucretius’ great poem, which was held in one single German library, which one single intrepid book hunter would eventually find and save from extinction. That single volume would have an astonishing afterlife: it became a literary sensation, returning atomism to European thought, created what Stephen Greenblat called “an explosion of interest in pagan antiquity” and influence Newton, Galileo and later Einstein." (page 40) Alas, not much else.
Alastair Chestnutt all I learned was Planck’s equation not why he made it. We really need more history in our sciences or everything comes from thin air.
@@Kathy_Loves_Physics I would argue that all disciplines should be be taught in a(n) historical manner. It enables one to get a glimpse of the process of thought. Love your videos!
Mark Stewart totally agree. However, I think literature, for example, is often told from an historical perspective whereas the sciences have been stripped of their stories. Glad you liked the videos 😊
Kathy, this is the best description of Plancks 'discovery' of QM that I have seen. The usual explanations are utter garbage and give no insight into how the quintessential theorist (derive from 1st principles guy) broke down and relied on the Wien's empricial equation. They just keep droning on about the UV Catastrophe and completely miss the point. It's very interesting that you say Planck used quantization as a mathematical trick to avoid the infinite energy paradox. I have to admit, I'm still not there yet with that, but I think Boltzman is key to my understanding. More reading needed. When I look at Planck's equation I don't see where it needs quantization. It seems to work very nicely without it. Anyway, keep up the fantastic work. I really look forward to everyone you do !!
I don't know how to comment but I want to comment " Your videos and Prof Walter Lewin lectures are giving one type of satisfaction to me in this restless highly dynamic world.Thank you mam" I read your biography and right now, I feel me as one of the kids sitting in your classroom in San Francisco... With lots of love💚 B T Balavinayagam
This comment made me feel so good. I am glad that I can add some sunshine in these dark days. And you made me look up Walter Lewin and realize that I had watched a ton of his videos without remembering his name! What an honor to put me in the same category as him. Thank you. Your teacher in spirit, Kathy
I am a chemistry major from 1982. Physical chemistry was a blur...until now! Thanks for the intriguing and amazing background on how quantum mechanics and relativity developed! Thanks!
Oh wow. “If you throw a cup of water into the sea, you can’t get the same cup out again.” That statement is the most profound thing about statistics I’ve ever learned about.
Before this video, physics research and its theories seemed completely discrete to me but now, after watching this video, they seem little less discrete. it has already connected some dots for me. i am new to this channel, i think i am gonna binge watch all of your videos and i think all these dots will be connected afterwards and an overarching structure of physics will be clear to me. Thank you Kathy!
Very convincing reasons. This is why relative-timing ratio-rates of resonant probability, is the temporal superposition log-antilog making of Everything in Statistical Theoretical Analysis, a Quantum Computational AM-FM In-form-ation substantiation, in/of self-defining Polar-Cartesian coordination in/of wave-packaging, be-cause-effect standing wave fractal bubble-modes of conic-cyclonic dimensionality.
Minute 8 comes to the point of the modern confusion about QM. The Planckian math exists in order to be able to say something about a continuous medium. For the purpose of math, we need to discuss reality in numbers, the equivalent of that for physics are numbered packets of energy. Nature is not quantized, nor is energy. Effects can be quantized (such as an orbital jump around an atom) , but the energy being pumped in to get quantized effects itself is continuous. The map and the conventions used to make the map are not the terrain. The problem is that many nowadays believe the map is the reality.
One of Plank's observations in his 20's lecture notes was that for heat radiation to interact w stuff the wavelengths and stuff dimensions needed to be comparable. For instance, cosmic and X-rays have very short high energy waves comparable to molecular dimensions and tear them apart. UV wavelengths are longer and lower energy so they can only displace electrons and produce fluorescence. IR wavelengths are very long and low energy and much larger than molecules and just pass through gases until they hit something substantial. Think standing under those IR heaters at Home Depot or near a propane fired patio heater. IR wavelengths are too long to interact w/ GHGs and cannot produce a greenhouse effect.
Browning motion-like presence in quantum field foam may be the basis of plank constant. Oscillation length may be plank length, and period ( pendulum) might be plank time. It is like walking on marbles that are vibrating.
I just want to go back in time and tell him to shave it off. He was so cute clean shaven and looked 100 years old with the "forkbeard" (he he). But looking at Boltzmann maybe those crazy beards were the fashion at the time.
Aww thanks. I did a whole biography of Max Planck because he’s just fascinating and I felt bad that this video didn’t include much of his personality or influence in the 20s
It's not entropy, but change in entropy that cannot be less than zero in a closed system, according to the 2nd law of thermodynamics. It's the 3rd law that says entropy is always positive and zero at zero Kelvin.
Wonderful video. One small comment: Wilhelm Wien's name is pronounced "veen", not "vine". Incidentally, Wien is also the German name for the city of Vienna.
I always thought the Nobel committee was weak to not give Einstein the prize for relativity. As if they were unsure whether it was correct. But you make the discovery of the photon from the photoelectric effect sound pretty cool too.
I am working through Planck's derivation of Wien's displacement law (Ch. III in Part II of his "The Theory of Heat Radiation). I *think* that I am starting to understand his train of thought and arguments. I'd love to learn (from, ahem, you) how Wien came to understand and derive his law. My brief searches on Google did not lead anywhere. All derivations I have seen (except for a 2000 paper by Cole) derive it from Planck's black body formula. Anyways, absolutely awesome videos.
Excellent content. Physics can sometimes be a very sterile topic but adding the history makes physics not only more enjoyable, but also more understandable and easier to assimilate.
So glad you liked it. Actually, when I started this I was just interested in the history, I wasn't expecting it to give me a deeper understanding of the science. And then, every single time, the context has made the physics so much richer and more memorable. It has been a blast. Kathy
Wow what a thriller of a video. As a Physics graduate of 39 years back connecting the dots between Physics, physicists, history and time line is just awesome 👌 when i retire i hope i can go back to studying Physics and figure out the equation for world peace, happiness and prosperity 😊 i am serious. I am no genius but i can dream right?

Kathy: you go enthusiastically where professors of physics circumspectly fear to tread. Some of the things you say are not quite correct but I'm a fan anyway...bravo and keep it up. Please don't take badly any criticism that you might encounter (from me or from others)...these concepts are not easy, and you breathe life into these names: Maxwell, Born, Planck, Kirchhoff, Wheatstone, Ohm so we see them for what they were...real human beings, making lots of mistakes just like the rest of us.
There are connections between quantum mechanics and consciousness . Consciousness is the intelligence, the organising principle behind the arising of form. The quantum field or pure consciousness is influenced by intention and desire. Animals express consciousness through instinct. Humans , in addition to instinct we possess the highest quality of consciousness, --self awareness. Consciousness is the intelligence, the organising principle behind the arising of form. The quantum field or pure consciousness is influenced by intention and desire. All atoms in the entire universe are capable of mind reading and communicating with other atoms. There is a consciousness in every molecule of matter. " Quantum theory will NOT look ridiculous to people who have read Vedas ” W Heisenberg Quantum scientist As per quantum physics things do not exist in its physical form, unless they are observed by a conscious observer. In every experiment when an observer expected energy to behave as a particle, it did so. When he thought it would probably be wave-like, it was. And when observers believed it might start out as one form and end up as another, it did so. This means ,nothing actually exists in its physical form until observed by someone, was adopted by the group as one of the concepts. You created them by your expectations and your thoughts of what should be. In every situation in your life, including the wealth or lack of it you choose to attract to you. Thanks to the theory of ERP Quantum Entanglement, originally asserted by Albert Einstein and two fellow scientists , Boris Podolsky and Nathan Rosen, we now have proof that what Vedanta had been saying for 9000 years is true.We are all connected. We are all One, sharing a consciousness with the entire universe, perhaps even many universes. On the subatomic level-mind is over matter. The brain and DNA is governed by the laws of quantum physics rather than the laws of biology or neuro physiology.
Regular history is about wars, kings, and queens, and mostly about the behavior of royal spoiled brats who got the poor to fight the wars that royalty got rich off of. Most of it is discard able. Far better to study the history of the greatest problem solvers since we will ALWAYS have problems to solve. Great work Kathy!!!
You’re quite welcome. If you like this video you might like my three pirate biography I did on Max plank which goes into a detail about his life and his influence on the progression of quantum mechanics
Hi Kathy. Have you read the book Einstein and the Quantum: The Quest of the Valiant Swabian, by A. Douglas Stone? He covers this story and more in tracing Einstein's involvement in quantum theory. Its a fun read, and I think you'd enjoy it! Its great to see another telling of the story here, and I'm looking forward to watching your related videos. Keep up the great work!
Just occurred to me the reason symbols are so 'successful' if you will is because they usually have hidden meaning, but that's not the reason, the reason is they both have the surface meaning and the hidden meaning represented only by one symbol: the kind of compression of information that goes into such a construct is what gives it depth
I've now watched this video several times and I really like the connective threads of research and theory that are made. I don't feel completely satisfied but am waiting for the next installments. It's such a cool story.
Charles Carlson Quantum stuff is odd and complex. It’s going to take me a long long time to get through even the basics of its history.

Kathy, this is the best description of Plancks 'discovery' of QM that I have seen. The usual explanations are utter garbage and give no insight into how the quintessential theorist (derive from 1st principles guy) broke down and relied on the Wien's empricial equation. They just keep droning on about the UV Catastrophe and completely miss the point.
It's very interesting that you say Planck used quantization as a mathematical trick to avoid the infinite energy paradox. I have to admit, I'm still not there yet with that, but I think Boltzman is key to my understanding. More reading needed.
When I look at Planck's equation I don't see where it needs quantization. It seems to work very nicely without it.
Anyway, keep up the fantastic work. I really look forward to everyone you do !!
Thank you so much for the lovely comment.
Look up Dan Winter on RUclips
I don't know how to comment but I want to comment
" Your videos and Prof Walter Lewin lectures are giving one type of satisfaction to me in this restless highly dynamic world.Thank you mam"
I read your biography and right now, I feel me as one of the kids sitting in your classroom in San Francisco...
With lots of love💚

This comment made me feel so good. I am glad that I can add some sunshine in these dark days. And you made me look up Walter Lewin and realize that I had watched a ton of his videos without remembering his name! What an honor to put me in the same category as him. Thank you. Your teacher in spirit, Kathy
I am a chemistry major from 1982. Physical chemistry was a blur...until now! Thanks for the intriguing and amazing background on how quantum mechanics and relativity developed! Thanks!
So glad I could help, sorry I wasn’t making videos in 1982
Oh wow. “If you throw a cup of water into the sea, you can’t get the same cup out again.” That statement is the most profound thing about statistics I’ve ever learned about.
Came from an ad and wasn't disappointed!
CrypticHeaven glad you liked it
long time since someone truly touched my heart by physics and history. I am glad I found your channel Kathy
I’m glad you found it too. Thanks
Wow, what a nice story you are plotting: Insightful, bringing in the characters and their interactions. Love it!!!
Thank you so much!
I loved this ♥️🥰🙏 More please, Ms Kathy!
Edit: The last minute was even more amusing and sweet :)
What a wonderful way to spend a few minutes of my life. thankyou
Congratulations. It served me so much. Thank you!
Thank you mam for ur lecture on scientists ,their scientific theories and their relations.
Amazing. I loved this theme and your explanation of it. Thank you very much from Brazilian fan.
Before this video, physics research and its theories seemed completely discrete to me but now, after watching this video, they seem little less discrete. it has already connected some dots for me. i am new to this channel, i think i am gonna binge watch all of your videos and i think all these dots will be connected afterwards and an overarching structure of physics will be clear to me. Thank you Kathy!
Going back to my physics classes during early 80's ❤️👻
I need a lot more statistical data about these guys. I see you have more videos. I will be watching soon enough. Thanks
These videos are a wealthy source of information that brings it all in order. Thank you
So glad you liked it
I learned about Rayleigh-Jeans in the 80s. Not only did they have holes in them, they were acid washed but they went well with my mullet.
I hope to see your channel grow. I love your style!
Excellent job 👌 easy to understand by hearing as a story with simple English
Very convincing reasons. This is why relative-timing ratio-rates of resonant probability, is the temporal superposition log-antilog making of Everything in Statistical Theoretical Analysis, a Quantum Computational AM-FM In-form-ation substantiation, in/of self-defining Polar-Cartesian coordination in/of wave-packaging, be-cause-effect standing wave fractal bubble-modes of conic-cyclonic dimensionality.
I totally love you. The way you present anything!, is brilliant!!
I love the love. Cheers, Kathy
Kathy.... I subscribed to your channel ❤
Oh yes, I love Physics and all the History that formulated what Physics and Mechanics are today.
Cheers to you🎊
Minute 8 comes to the point of the modern confusion about QM. The Planckian math exists in order to be able to say something about a continuous medium. For the purpose of math, we need to discuss reality in numbers, the equivalent of that for physics are numbered packets of energy. Nature is not quantized, nor is energy. Effects can be quantized (such as an orbital jump around an atom) , but the energy being pumped in to get quantized effects itself is continuous. The map and the conventions used to make the map are not the terrain. The problem is that many nowadays believe the map is the reality.
One of Plank's observations in his 20's lecture notes was that for heat radiation to interact w stuff the wavelengths and stuff dimensions needed to be comparable.
For instance, cosmic and X-rays have very short high energy waves comparable to molecular dimensions and tear them apart.
UV wavelengths are longer and lower energy so they can only displace electrons and produce fluorescence.
IR wavelengths are very long and low energy and much larger than molecules and just pass through gases until they hit something substantial. Think standing under those IR heaters at Home Depot or near a propane fired patio heater.
IR wavelengths are too long to interact w/ GHGs and cannot produce a greenhouse effect.
Browning motion-like presence in quantum field foam may be the basis of plank constant. Oscillation length may be plank length, and period ( pendulum) might be plank time. It is like walking on marbles that are vibrating.
Never seen that photo of Forkbeard Maxwell before. Worth the price of admission by itself.
I just want to go back in time and tell him to shave it off. He was so cute clean shaven and looked 100 years old with the "forkbeard" (he he). But looking at Boltzmann maybe those crazy beards were the fashion at the time.
I enjoyed your explanation. Thanks!
Good stuff. Thanks for uploading.
Glad you liked it.
A superb presentation....the best I heard.
Aww thanks. I did a whole biography of Max Planck because he’s just fascinating and I felt bad that this video didn’t include much of his personality or influence in the 20s
You are just great. Thanks for doing these
I love you! Thanks for uploading this!
absupinhere you are welcome.
It's not entropy, but change in entropy that cannot be less than zero in a closed system, according to the 2nd law of thermodynamics. It's the 3rd law that says entropy is always positive and zero at zero Kelvin.
steppenwolf I am so embarrassed. Of course you are totally correct. Thank you for pointing out my misstatement. Oops.
@@Kathy_Loves_Physics it happens, but the equation on the screen stated it properly, so it's ok.
thanks for this awesome summary!
Wonderful video. One small comment: Wilhelm Wien's name is pronounced "veen", not "vine". Incidentally, Wien is also the German name for the city of Vienna.
I always thought the Nobel committee was weak to not give Einstein the prize for relativity. As if they were unsure whether it was correct. But you make the discovery of the photon from the photoelectric effect sound pretty cool too.
These are really good. The hands are distracting so the close up shots help.
I am working through Planck's derivation of Wien's displacement law (Ch. III in Part II of his "The Theory of Heat Radiation). I *think* that I am starting to understand his train of thought and arguments. I'd love to learn (from, ahem, you) how Wien came to understand and derive his law. My brief searches on Google did not lead anywhere. All derivations I have seen (except for a 2000 paper by Cole) derive it from Planck's black body formula. Anyways, absolutely awesome videos.
After watching i am thinking to give my whole life in quantum physics...❤️
Excellent content. Physics can sometimes be a very sterile topic but adding the history makes physics not only more enjoyable, but also more understandable and easier to assimilate.
So glad you liked it. Actually, when I started this I was just interested in the history, I wasn't expecting it to give me a deeper understanding of the science. And then, every single time, the context has made the physics so much richer and more memorable. It has been a blast.
Kathy
Kathy Loves Physics & History I agree. See my reply to soccer guy.
Wow what a thriller of a video. As a Physics graduate of 39 years back connecting the dots between Physics, physicists, history and time line is just awesome 👌 when i retire i hope i can go back to studying Physics and figure out the equation for world peace, happiness and prosperity 😊 i am serious. I am no genius but i can dream right?
It's An AMAZING video... That's what i want Some history and why they have this ideas...

Fantastic video. Interesting and well explained. Thank you!
Glad you liked it.
Kathy: you go enthusiastically where professors of physics circumspectly fear to tread. Some of the things you say are not quite correct but I'm a fan anyway...bravo and keep it up. Please don't take badly any criticism that you might encounter (from me or from others)...these concepts are not easy, and you breathe life into these names: Maxwell, Born, Planck, Kirchhoff, Wheatstone, Ohm so we see them for what they were...real human beings, making lots of mistakes just like the rest of us.
Thank you
Ok, on an educational video you can't just say some things are not correct without saying which ones and then correcting them.
@@Kathy_Loves_Physics By the way, it's amazing your responding to comments in videos that are years old. I deeply respect your commitment.
@@magtovi Please read my earlier comment on Kathy's description of what the 2nd law of thermodynamics says.
There are connections between quantum mechanics and consciousness .
Consciousness is the intelligence, the organising principle behind the arising of form. The quantum field or pure consciousness is influenced by intention and desire.
Animals express consciousness through instinct. Humans , in addition to instinct we possess the highest quality of consciousness, --self awareness.
Consciousness is the intelligence, the organising principle behind the arising of form. The quantum field or pure consciousness is influenced by intention and desire.
All atoms in the entire universe are capable of mind reading and communicating with other atoms. There is a consciousness in every molecule of matter.
" Quantum theory will NOT look ridiculous to people who have read Vedas ”
W Heisenberg
Quantum scientist
As per quantum physics things do not exist in its physical form, unless they are observed by a conscious observer.
In every experiment when an observer expected energy to behave as a particle, it did so. When he thought it would probably be wave-like, it was. And when observers believed it might start out as one form and end up as another, it did so.
This means ,nothing actually exists in its physical form until observed by someone, was adopted by the group as one of the concepts. You created them by your expectations and your thoughts of what should be. In every situation in your life, including the wealth or lack of it you choose to attract to you.
Thanks to the theory of ERP Quantum Entanglement, originally asserted by Albert Einstein and two fellow scientists , Boris Podolsky and Nathan Rosen, we now have proof that what Vedanta had been saying for 9000 years is true.We are all connected. We are all One, sharing a consciousness with the entire universe, perhaps even many universes.
On the subatomic level-mind is over matter. The brain and DNA is governed by the laws of quantum physics rather than the laws of biology or neuro physiology.
Amazing video!!! 🔥🔥🔥
Many thanks for sharing! 👏👏👏
I luvvvv your videos, keep posting !
As always absolute pure gold .
Hi Kathy, I knew it....hooked me to another video. Lucky for Starbucks!
Regular history is about wars, kings, and queens, and mostly about the behavior of royal spoiled brats who got the poor to fight the wars that royalty got rich off of. Most of it is discard able. Far better to study the history of the greatest problem solvers since we will ALWAYS have problems to solve. Great work Kathy!!!
Thank You, Kathy.
You’re quite welcome. If you like this video you might like my three pirate biography I did on Max plank which goes into a detail about his life and his influence on the progression of quantum mechanics
Hi Kathy. Have you read the book Einstein and the Quantum: The Quest of the Valiant Swabian, by A. Douglas Stone? He covers this story and more in tracing Einstein's involvement in quantum theory. Its a fun read, and I think you'd enjoy it! Its great to see another telling of the story here, and I'm looking forward to watching your related videos. Keep up the great work!
Just occurred to me the reason symbols are so 'successful' if you will is because they usually have hidden meaning, but that's not the reason, the reason is they both have the surface meaning and the hidden meaning represented only by one symbol: the kind of compression of information that goes into such a construct is what gives it depth
thank you so much for this!
You are amazing..Talks so well
Well done historical presentation, not meant as a development of the Research, but is appropriate for preparing researchers..?
These videos are fantastic. So good.
A symetry of physists. I love it.😊 How one discovery leads to another.😊
This was awesome! Very informative!
