The Simple Math that Led Einstein to Relativity

Einstein turned the world on its head in November of 1919, when data collected during a solar eclipse matched the predictions of his Theory of General Relativity. But Einstein’s path to discovering his theory traces back much further, to when he was 12 years old and he first learned about an ancient mathematical method…

*A Note about how I use AI generated images in my videos*
The emerging ability of artificial intelligence to generate compelling images from text prompts opens new possibilities for compelling storytelling. However, when mixed with real historical imagery, as is in my video, it has the potential to create confusion, or worse, if not handled properly.
I have set a few guidelines for my use of AI generated images in this video so that a viewer can easily understand which images are real photographs and which are synthetically generated:
ALL images that have been placed in a “frame” (eg a border that resembles an old photo print, etc) are REAL historical images.
ALL images that include Einstein's full face, as well as all World War I related images, are REAL historical images.
I have used Midjourney AI to create “stock” image elements including backgrounds, illustrations, and objects.
I have used Midjourney AI to create some images that are implied to be of Einstein. In these, Einstein’s face is FULLY OR PARTIALLY OBSCURED.
Please send me a message or drop a comment and I'll be happy to clarify any specific images.

This video twists a lot of things out of physics, truth and facts about Einstein. Axioms are entities accepted by humanity as evident truths. So, if I - by algebra - start shuffling the Pythagorean theorem by algebra rules and then begin working backwards by different algebra rules, I will come back to the point of my start. By multiplying a^2+b^2=c^2 by a constant and then during reversal and by using a different algebraic method I will come back to the original equation. So, the proof is circular here and really it does not prove anything besides the well established fact of Pythagorean theorem. It is not true that Einstein was the first to come up with the idea of relativity. Gauss, Bernhard Riemann, and Ernst Mach for general relativity. Subsequently, claims have been put forward about both theories, asserting that they were formulated, either wholly or in part, by others before Einstein who was not a mathematician but physicist. Einstein was bad at math. Grossman and his wife Mileva were doing math for Einstein. The video makes a blunder at 18:31; the astronaut depicted is surrounded by gravity constantly for gravity is in Universe's space all over. It is because the gravity that the astronaut is in FREE FALL and not isolated from gravity. This is the cardinal mistake that physics students make in class thinking that a spaceman is floating because there is no gravity in his surrounding. THERE IS GRAVITY THERE but he is in precisely free fall because of gravity. Einstein stole lost of ideas and works of other people. For example the Schwartzchild's metric tensors were incoroporated in GR by Einstein and Einstein worked on them but could not come up because tensor math is extremely difficult and Einstein was not a mathematician and the tensors are not his. Einstein never gave the definition of time. How can one work with time with no definition of it? Also, space is not a flat sheet of cloth on which stars and planets are placed. Time can't have a direction as depicted on the space-time diagram because we are dealing with something substantial (space; we can measure it as a volume ) and an elusive entity (time) which can't be measured with a sentient device. Therefore, clocks have nothing to do with time for a clock does not feel time and moreover clocks have nothing to do with time as you try to measure time with a broken clock. Does a broken clock have anything to do with time? No, a broken clock or efficient clock have nothing to do with time not even atomic clocks. Einstein did not come up with anything new and he did not come up with E=mc^. The equation of E=mc^2 DOES NOT belong to Einstein ! ! ! Before him there was Samuel Tolver Preston who developed the theory of relativity even before Einstein was born. Einstein is not the maker of E=mc^2. In Einstein's first paper about energy and mass, E=mc2 doesn't actually appear anywhere-he originally wrote the formula as m=L/c2. It was the Italian amateur physicist Olinto de Pretto who published E=mc^2 in 1903 and Einstein's Italian friend physicist Besso was given that equation by Olinto. Besso took that equation and gave it to Einstein. And Einstein plagiarized it changing the equation later on. Einstein was a plagiarist. Link: kzbin.info/www/bejne/nKSyk5RoqtWfoNk

Whether gravity is fictitious (just an artefact of accelerated frames) or real (contains tidal forces that cannot be co-ordinate transformed) is the same as asking whether geometry is flat or curved was Einstein's key insight! Riemann probably never thought in his wildest dreams that his math would be useful to model curved spacetime. That's incredibly insane. Thanks for this wonderful video, Ben. I loved how the video slowly put all the pieces together. Wow! Also, thanks for the shoutout. Cheers!

For example, in my summary of Einstein's thought experiment about the astronaut in outer space.

Well for example the proof of the Pythagorean theorem. The proof itself is completely rigorous and you can read more about it here: www.newyorker.com/tech/annals-of-technology/einsteins-first-proof-pythagorean-theorem I think what you’re responding to there could be the way that I keep referring back to the Pythagorean theorem itself as I walk through the reasoning of the proof, as a way to help a less knowledgeable viewer stay oriented.

"This was when Einstein came upon what he later called the happiest thought of his life. He imagined a painter falling from the side of a building-" This made me laugh

[@bensyversen]

I’m glad it made you laugh! I think it’s funny too. There were a few variations of this story that floated around in the press at the time (eg did he actually SEE a painter falling, or did he just imagine it?), but the basic idea of Einstein envisioning a thought experiment similar to this is pretty solidly in the typical telling of the story at this point. It’s possible though that Einstein was having a bit of a laugh to some degree at the expense of the reporter - don’t forget that he WAS more than just a little bit of a troublemaker…

Besides Minkowski and Grossman, Einstein also received help from Constantine Caratheodory, a Greek Mathematician considered one of the best of the 20th century. Caratheodory researched and wrote his PhD under the supervision of Minkowski at the University of Gottingen.

[@bensyversen]

Wow I will look him up, thank you. I knew that Einstein consulted with other mathematicians as well, but I didn't encounter their specific stories in most of the sources that I consulted.

[@feynmanschwingere_mc2270]

Dirac needed the help of Weyl and Oppenheimer for his famous Dirac equation. Leibniz published calculus before Newton did. And consulted the works of Fermat and Descartes before publishing the error-riddled masterpiece Principia Mathematica. There is no such thing as a "lone" genius. Einstein's "problems" in mathematics didn't stop him from predicting stimulated and spontaneous emission; nor entanglement; nor Bose-Einstein Condensates; etc. And in your video, you make a glaring omission: the REASON Einstein BEAT Hilbert to the final field equations of General Relativity is precisely because Einstein understood the necessity of a coordinate system that was generally covariant - Hilbert did NOT grasp this until it was too late (even though as the premier mathematician of his day, he should have known this). The video does a great job of humanizing Einstein, foibles and all, while treating the other characters with a deference that they don't deserve. Michelle Besso deserves a bit of a shout out for helping Einstein as well. For instance, you make no mention of the fact that it was Einstein's openeness to share his ideas with Hilbert after Hilbert invited Einstein to Gottingen to give lectures on relativity theory that LED to Hilbert trying to "nostrify" Einstein's work. You also don't make it entirely clear that it was more likely than not that Hilbert had copied ideas from Einstein from reading a preprint of his November 1914 paper. You'd think Hilbert, not Schwardschild, would have come up with the first exact solutions to GR. And you'd think Grossman, as the professional mathematician, would have identified general covariance as a necessary framing for making use of a coordinate system, but they did not. You should also do a deep dive on how Heisenberg needed Max Borns MATH and how Born, not Heisenberg, but matrix mechanics into quantum theory. Also do a deep dive on how Einstein got about 33% of the way to what is now known as The Schrodinger Equation, and that without Einsteins direct help, Schrodinger likely never gets to discover the very thing he's most famous for (as Schrodinger always acknowledged). Or how Max Born credited Einstein with the idea of probability waves. It's become en vogue to declare all the "help" Einstein got as a way to humanize him. However, the opposite is also true. Einstein GAVE a lot of help to scientists who took his ideas without attribution and he often gets overlooked for ideas he came up with. De Broglie is a great example. He took Einsteins equations in his 1906 - 1909 papers on quantization of energy and applied them to a gas of electrons, rather than photons as Einstein had done, and got matter waves. Or how Einstein predicted the boson (which really should be called an Einsteinion) after Schrodinger completely misunderstood Bose's paper so thoroughly, Einstein had to write a letter to Schrodinger showing an example of the new quantum statistics (e.g. 1/3 instead of 1/2).

@@feynmanschwingere_mc2270 Hi, thank you for watching my little video and for taking the time to write this very thoughtful comment. You are certainly right on these points about the people and information that I left out of my video. In fact, I very much wanted to include something about Besso, AND more detail about Einstein and Hilbert's relationship. However, this video's runtime of 30 minutes very much pushed me to my limit as a fledgling video creator, so I had to cut fairly ruthlessly, keeping the total number of historical "characters" introduced in my narrative at 6 (Einstein, Minkowski, Grossmann, Riemann, Hilbert, Eddington) and leaving out any detail that would provide more refinement to other people involved besides Einstein. (As far as the discussion of WHY Einstein beat Hilbert, it is a fascinating detail but I thought that it could be a little bit too "in the weeds" for a general audience). Do you have any favorite books or resources that you would recommend to viewers who are interested in learning more about these figures and the relationships that you describe?

Omg! This adds such a depth to the development of Einstein’s theories that I have never seen. I love this addition of seeing what he saw as a child, that lead him to develop theories and then having others expand upon those theories and leading him to appreciate math he had previously found unhelpful. It really digs into the importance of how we educate our youth. Something I am passionate about. I hated math. Same situation you mention in this video, how am I ever going to use this complex math in my life? What is the point on learning this? Later in life I grew to appreciate that same math when I grew fascinated by naked eye Astronomy. First looking at stars. Constellations. And eventually planets. And I wanted to know how we figured it out. Thousands of years ago. Without calculators or computers.

Dirac needed the help of Weyl and Oppenheimer for his famous Dirac equation. Leibniz published calculus before Newton did. And consulted the works of Fermat and Descartes before publishing the error-riddled masterpiece Principia Mathematica. There is no such thing as a "lone" genius. Einstein's "problems" in mathematics didn't stop him from predicting stimulated and spontaneous emission; nor entanglement; nor Bose-Einstein Condensates; etc. And in your video, you make a glaring omission: the REASON Einstein BEAT Hilbert to the final field equations of General Relativity is precisely because Einstein understood the necessity of a coordinate system that was generally covariant - Hilbert did NOT grasp this until it was too late (even though as the premier mathematician of his day, he should have known this). The video does a great job of humanizing Einstein, foibles and all, while treating the other characters with a deference that they don't deserve. Michelle Besso deserves a bit of a shout out for helping Einstein as well. For instance, you make no mention of the fact that it was Einstein's openeness to share his ideas with Hilbert after Hilbert invited Einstein to Gottingen to give lectures on relativity theory that LED to Hilbert trying to "nostrify" Einstein's work. You also don't make it entirely clear that it was more likely than not that Hilbert had copied ideas from Einstein from reading a preprint of his November 1914 paper. You'd think Hilbert, not Schwardschild, would have come up with the first exact solutions to GR. And you'd think Grossman, as the professional mathematician, would have identified general covariance as a necessary framing for making use of a coordinate system, but they did not. You should also do a deep dive on how Heisenberg needed Max Borns MATH and how Born, not Heisenberg, but matrix mechanics into quantum theory. Also do a deep dive on how Einstein got about 33% of the way to what is now known as The Schrodinger Equation, and that without Einsteins direct help, Schrodinger likely never gets to discover the very thing he's most famous for (as Schrodinger always acknowledged). Or how Max Born credited Einstein with the idea of probability waves. It's become en vogue to declare all the "help" Einstein got as a way to humanize him. However, the opposite is also true. Einstein GAVE a lot of help to scientists who took his ideas without attribution and he often gets overlooked for ideas he came up with. De Broglie is a great example. He took Einsteins equations in his 1906 - 1909 papers on quantization of energy and applied them to a gas of electrons, rather than photons as Einstein had done, and got matter waves. Or how Einstein predicted the boson (which really should be called an Einsteinion) after Schrodinger completely misunderstood Bose's paper so thoroughly, Einstein had to write a letter to Schrodinger showing an example of the new quantum statistics (e.g. 1/3 instead of 1/2).

[@bensyversen]

Hi, thank you for watching my little video and for taking the time to write this very thoughtful comment. You are certainly right on these points about the people and information that I left out of my video. In fact, I very much wanted to include something about Besso, AND more detail about Einstein and Hilbert's relationship. However, this video's runtime of 30 minutes very much pushed me to my limit as a fledgling video creator, so I had to cut fairly ruthlessly, keeping the total number of historical "characters" introduced in my narrative at 6 (Einstein, Minkowski, Grossmann, Riemann, Hilbert, Eddington) and leaving out any detail that would provide more refinement to other people involved besides Einstein. (As far as the discussion of WHY Einstein beat Hilbert, it is a fascinating detail but I thought that it could be a little bit too "in the weeds" for a general audience). Do you have any favorite books or resources that you would recommend to viewers who are interested in learning more about these figures and the relationships that you describe?

Excellent Video! This is a Netflix worthy documentary! One small note - I think it would be better if u included the Michelson-Morley experiment on how the speed of light is constant in all reference frames to explain how Einstein got his postulate for special relativity

[@bensyversen]

Thank you for your very kind comment! As far as the Michelson-Morley experiment, this was one of the juicy historical tidbits that I came across in researching this video that I had to leave out for time purposes: It’s actually unclear whether Einstein was familiar with the Michelson-Morley experiment at the time that he wrote his 1905 paper (the physics taught at Zurich Polytechnic at the time that he attended was somewhat dated, and when he worked at the patent office he had a hard time keeping up with the latest research because the library was closed by the time he got off of work). Einstein himself said different, slightly conflicting things over the years: physics.stackexchange.com/questions/89375/did-einstein-know-about-the-michelson-morley-experiment/89379#89379

[@bensyversen]

There are two reasons why I love this historical tidbit so much: 1) It reminds us that history is messier than just connecting the dots chronologically. Human elements played a role back then, just like they do in our own lives. 2) Like so many of us, Einstein was once a 20-something with a day job and a dream (and a pregnant girlfriend, but that's a whole other story that I also had to leave out of the video...), and sometimes his day job got in the way of his dream.

[@leonhardtkristensen4093]

@@bensyversen In my opinion there is no proof in the Michelson-Morley experiment or for that matter any other experiments that I have seen that the speed of light is constant in all reference frames. In every one I have seen it is the "Two way" speed that is measured as far as I can see. It is my opinion that the speed of light is probably constant but from a constant stand still meaning that any moving observer should see the speed being slower (red shifted) if you are moving away from it's origin and faster if you move towards it's origin. The time dilation is correct I believe. That has to do with time keeping that on the very small scale (in the atoms) must have to do with the electro magnetic propagation speed. Time itself is a different story i believe. I believe it only exist right now. Time gone only exist as a memory and the future is yet to come but that is philosophy. That any body's time moving at any speed should go slower than my time if I am the observer I believe is wrong. If not then a light beam emitted from my point of view should move away from me with the speed of light even though I might be moving nearly as fast in the same direction.

<a href="#" class="seekto" data-time="1726">28:46</a> even more ironic and interesting is that the brilliant Bernhard Riemann while a student at university was assigned in a sense a doctorate thesis research topic to formulate a generalized geometry that would extend beyond classic Euclidean "flat" geometry.

Einstein's Pythagorean Theorem uses scale-symmetry, and that's what gave him relativistic intuition. Wish I could show him my d=(c-b)/a base scale. Maybe he could've used it for simpler gravity math. Thanks for the insight that a cone is Thales Theorem with infinitely sized radii.

[@bryandraughn9830]

I was reading about Eddington and his full story along with another guy who was on a similar mission and it was a huge accomplishment with many obstacles. According to the story I read Einstein even had time to make some type of correction to his prediction before the final results had been made. I wish I could remember where I found it.

[@bensyversen]

Yes there was a whole earlier expedition that I really wanted to include in the video but left out due to time and relevance. Basically, there was a solar eclipse happening in 1914 in the Crimean peninsula, which was a part of Russia at that time. Einstein found a young German astronomer named Erwin Freundlich and helped arrange the funds to set up the expedition (I think he even paid some out of pocket). Freundlich and team arrived in the Crimea several weeks before, and then World War I broke out. Since Germany and Russia were now enemies, the team was arrested and their equipment confiscated. (They were eventually sent home) This was all lucky for Einstein though, because his prediction at that point was wrong. It was basically in line with the prediction that would have come from treating light as a particle with mass using the Newtonian model. I read about this in the Walter Isaacson biography of Einstein, but here is a more detailed article on the topic: www.machinedesign.com/automation-iiot/article/21835940/how-wwi-saved-einsteins-theory-of-relativity

@<a href="#" class="seekto" data-time="1780">29:40</a> The TL:DR is.. Nothing, I ramble aimlessly. I love the point being made here, about the mathematicians coming up with their crazy stuff, no one paying much mind to it, for decades, until one day someone realizes it's exactly what is needed to explain something else. I like learning about how "we" know what we know (yes, "we" is doing a _lot_ of lifting here), and how the kernel of an idea can be picked up, put down, and eventually end up sidelined, possibly for years, before finding its way to someone who is at the right place, and time, to be able to recognize it is a missing piece of a breakthrough puzzle. It happens a lot, and it's nuts how often someone has come up with something that didn't find a practical use in their niche area of expertise, but turned out to be in some way central to the progress of another, sometimes long after the original author/ creator has shuffled off this mortal coil. I read a few of the speeches/ talks, articles and interviews that Einstein did, and something he made a point to discuss, more than once, was the importance learning the history of, and reading good works in the philosophy of science. It seems like it should be a no brainer, really, but some really nerdy people are bizarrely blinkered. Einstein seemed to consider this knowledge to be key to future progress. I personally think that the "shut up and calculate" contingent of modern physics, those who have been vocal about their disdain for the notion of philosophy having merit, at all, are possibly some of the most confused people on the planet, right now. It is hilarious to hear several someones who aren't even a little bit your practical, hands on, experiment devising/ conducting type of physicist, snarking that philosophy is garbage because you can't further the fields of physics, by (paraphrasing), sitting in a chair thinking really hard about things. Like, uh, projection, maybe? Or, seriously confused about the fundamental nature of what it is that they're doing when they're trying to solve problems by sitting on their arse, thinking really hard about things? I know ostensibly the idea is that their work will lead to something that a testable hypothesis can be created from, that will have practical use, progress the field and what have you, but until that time, they're just engaging in using very, very advanced math to represent the values of processes and physical constants, involved in very complex ways, which are derived using the axioms of mathematics, an understanding of the nature of the interactions, and by thinking really hard about it all... It's really complicated, logically rigorous and robust, very niche, tunnel visioned philosophy, really. Point is, Einstein was obviously correct to point out how important it is to learn and understand how progress and breakthroughs happen. If you pay attention to history, there is a predictable pattern of breakthrough - Flurry of progress and understanding - over confidence in some newly created concepts/ notions (s) that emerge, - hubris - academics chasing their own tails while inexplicably doubling down on defending a very obviously incompatible idea /or three - Philosophically inclined contributors begin to converge on concepts that lead directly to the next paradigm shifting breakthrough - Flurry of progress.... and on it goes. We need a few more academics with outlooks like our happy math genius here, embracing the philosophical and using it as the invaluable tool it has been, I think there is a shift already happening, away from the philosophically phobic view, which fills this rambling moron's heart with joy -

For sure. There's a narrative that goes around that's not quite right, which says that Einstein wasn't a good math student. He mastered differential and integral calculus at 16, so he was definitely no slouch. But at the same time he was a bit of a troublemaker when it came to relationships with his teachers. And as I understand it, college was when he started to get lazy in math class because he didn't think it was important.

One more thing which could be mentioned (but not essential in an overview) is that Rieman tensor was not suitable for solving the problem. This requested to switch to Ricci tensor (Rieman's is a matrix of matrices, while Ricci's is a matrix of scalars, to simplify a bit) while subtracting 1/2 of the Ricci scalar (the trace of the tensor) including the metrics (g(μ)(ν)). To do this he had to ask for the help of Tullio Levi Civita, who would teach Einstein this kind of math. Einstein had really to delve in complex mathematics to solve his problem!

[@bensyversen]

Thank you! Yes the story is more complex than the format of this video really allows room for. In addition to Tullio Levi Civita, other commenters have also highlighted Constantine Caratheodory's contribution to Einstein's understanding of the mathematics involved.

Length contraction is about the scale applied to space not the quantity of space (e.g. size). It is the mechanism for acceleration in a particle accelerator after the initial boost. The particle beam is because the time container is too small for the space contained. Time scales space is a critical conclusion of Relativity. GR then applied that concept to show the mechanism for gravity. Length contraction in Galilean Relativity was about change in position. It wasn’t about the size of a thing either. Common misconception leading to the erroneous concept of spaghettification…. But that’s a whole other story.

[@harrybarrow6222]

I would think that by 1905, Einstein would have heard of the Michaelson-Morley 1887 experiment. The idea was that if light was a wave motion, it must be waves in something that filled space, the “luminiferous aether”. Since the Earth presumably was moving through the aether, you should be able to measure the speed of light as different in different directions. However, Michaelson & Morley did the experiment and could find absolutely no difference in speed for different directions and for different times of year. The speed of light seemed to be constant - which seemed nuts. If Einstein had heard of these experiments, that would be the reason for his second postulate.

[@bensyversen]

Yes. The answer to this question is a bit ambiguous though. Einstein didn't reference the experiment in his writings until 1907, and he said mixed things at different times in his life about whether or not he was aware of the experiment prior to his 1905 paper. physics.stackexchange.com/questions/89375/did-einstein-know-about-the-michelson-morley-experiment This might seem improbable in retrospect where the experiment is seen as such an important moment in the timeline of physics. But I'm not sure exactly how well-known and widely disseminated the M-M experiment would have been at that time: this was long before the internet after all. Also, Einstein's school did not emphasize the latest developments in physics so it is reasonable to think that he might have had some blind spots.
