I am a retired civil engineer who is fascinated by cosmology and quantum mechanics. I am devouring these topics with a passion hitherto unseen by man! 😄 Thank you, Mr. G.
I am a retired medical physicist and my recall of Special/General relativity learned in undergraduate courses has become rather warped over time (pun intended). Moreover, my lifetime of physics experience causes me to now "dig deeper" and seek intuitive/graphical understanding of these fields (no pun intended). I deplore numerous relativity textbooks that "hide" behind equations and the algebraic gymnastics of finding their solutions, without intuitive interpretation of the main terms and their units. This is where your videos are unique by providing clear intuitive interpretations and illustrations. Thank you for helping so many viewers understand relativity conceptually. Richard Feynman would be proud of your teaching content and style! 🤓
This is fantastic! I've subscribed to a lot of physics channels, but you have achieved the following: 1) Seized the bull by the horns by the explaining the equations themselves; 2) Explained them in a way so intuitively, precisely and compactly that even an amateur like me feels he understands them (instead of just getting eyestrain, as used to be the case).
I'll be honest, when I first saw the equation, I was quite intimidated, but I truly appreciate the explanation in micro-chunks with visuals. Thankfully, I learned tensors as part of TensorFlow package while learning to program machine learning. This has given me all the knowledge and confidence to take me to that next level of understanding! Thank you so much!!
Hey parth... also please explain 1.Why we are adding cosmological constant 2. Why we divide with C^4 4. Why C^4 4. Why there is 8pi.. Explain all these stuffs
This fantastic concept i.have since my childhood,this concept visualises a future of reaching to heavenly space distances in smaller affordable time. Well and good wishes to the partaker in this direction.
I like your pace and the fact that all of what you say is information, and closely related to what you intend to explain. Much, much appreciated!! Congratulations!
Great video. Just a quick note that it looks like you forgot to increment your Mu index in the matrix / tensor description at 6:30 and 6:50. They are all showing first index = 0, but as an example your pressure terms should be (1,1), (2.2), and (3,3).
I've been on a GR binge lately, and I'm so happy you never used the John Archibald Wheeler quote Yes, as a matter of fact I DO know that spacetime tells matter how to move, and matter spacetime how to curve. I think it sunk in somewhere around the eightieth time I heard it.
Thank you very much ! Remembering that tensors are here 4X4 matrices quiet helped to understand how these 3 little terms are supposed to describe the universe! Awesome videos as always!
Ya know. I'm a physics graduate as well, but my job isn't related to physics at all. Making an educational channel like yours that doesn't water down concepts into obtuse examples, and instead delves into the math and equations, would be awesome! If I ever start this channel, I will send you an email thanking you for being an inspiration!
It is so exciting to find your videos. I'm a fan after only watching a couple. I love physics especially Quantum mechanics and Relativity, but sadly I never formally studied it or maths because of various complexities in my personal history. I have a question that I've been posing to a variety of great communicators of physics, especially on relativity. Your title suggested you would answer it but you didn't. So far no one else has been able to answer it. I loved the way you explained the equations of General Relativity and it was a great help and it confirmed that it doesn't answer my question even though in your explanation you use words that suggest you are answering my question. You say these equations tell us "how mass bends space-time." But they don't. They tell us that mass causes space-time to curve or bend. Brilliant! They help us MEASURE the effect of Mass on space-time very accurately. Brilliant! But not what CAUSES the curvature that would be the true HOW of the curving effect. It is as if you were saying that measuring the current in amps tells us what electricity is and how it works. Our capacity for measuring current is very accurate, it tells us a lot that is useful and important, but it's not quantum mechanics which helps us understand electricity (and its related topics of electromagnetism and matter) in profound ways. It seems to me if we truly practically understood the mechanism for how matter interacts with space-time, we'd get closer to the much sought so-called "theory of everything". In your video, on the basic postulates of quantum mechanics, you talked about the "kinetic theory of gases". You said that if you change the size of the enclosing space of gas then the standard theory falls over. We know that a gas under pressure requires a different explanation as it is liquified and the temperature changes. Is this analogous to what happens in a black hole? More importantly, is there a way of talking about how space-time works inside matter, whether talking about a planet or a lump of metal? How do state changes in matter affect space-time? Since there is a change in the space (at least) occupied by matter in different states. Further different types of matter can occupy the same size space but have different effects, such as weight, on gravity, therefore space-time.
I am currently reading life story of Einstein by Walter Isaacson ( brilliant book by the way) and came across the Einstein Equation of general relativity. I wanted to understand the terms in the equation and what they represented physically. Many thanks for a very clear and concise explanation.
Thank you young man, for this lucid description! Not that u've made me a GR expert 😁, but now I know how the structure of GR, though complex, leads to varied derivations - black hole, big bang, gravitational warp ... It is all to do with different values of the tensors involved. Thanks again.
10:44 nice, for some reason this is the first time that clicked for me. All of space expands so things further away from any point in space will appear to move away faster from the perspective of that point.
your style of teaching is very unique and educational. please keep making videos and don't give up. you deserve a million followers and it takes time to get there. but your styles guarantees it.
It always confuses me to see spacetime as flat sheet. Some videos on it would be great to see some day. This concept just doesn’t sink in. Love matrix explanations, thankyou
Gravity changes every tangent space of space-time, leaving space-time unaltered. Add up the changes of every tangent space, and one can say a path is curved due to the tangent space. It may be a detail, but it exists in every metric tensor used in Einstein's field equations: τ² = t² - (x²+y²+z²)/c² is NOT the same as dτ² = dt² - (dx²+dy²+dz²)/c² - it is the second one that is used in GR, and the field equations are only relevant to tangent spaces of space-time. Even for a technical audience, this detail is respected in equations but not in our verbal descriptions of what is happening. People do not wish to consistently pre-pend "tangent space of" to space-time. If you have consistently said the "tangent space of space-time" hundreds of times, then all the action of gravity does not happen to space-time, but the tangent space of space-time. That allows space-time to be quite dull - the place where-when stuff is to a particular observer - and the activity we call gravity happens in the tangent space.
Paarrthhhhh this is amazing! I am trying to study for my GR module and could do with many more videos on it Tensors, Christoffel Symbols, basically Tensor calculus Hope you can make these!! Love your videos! 😁
The description was perfect, I always wanted to know about the mathematics behind the field equations but can you explain tensors in detail, I really want to know about them. Also, subscribed first then watched the video😁😁.
Great video. It would be very interesting if you would make some approximations (low mass, low speeds) and show how Einstein's equation collapses to Newtons gravity equation.
time is just like looking down a corridor. At the end of the corridor is death. except that we have a magnifying glass so we only see 1 bit of the corridor at a time
Hi and thank you a lot for these great videos. - I have a simple question about this one : Shouldn't be minus before the constant of expansion in the general equation ? Because in principle the expansion affects the curvature, isn't it ? - I saw the great videos about Maxwell equations and I hope you can complete the series with one about the fourth equation, please ! Thanks again
Thank you so so much! Your videos feed curiosity in an amazing and relaxing way! I love your calm energy - it definitely helps the nerdy learning :))))
These videos are rad. I'm just an average dude but I chose physics path, and all my colleagues are smarter than I am.... but it still makes me feel worthy when I see friendly people putting up such good explanations of these concepts that even I can understand. Haha
Parth G I'm not a mathematician and been trying in simple terms to understand how the equation cause time to slow on the surface of a planet compared to to further away from the surface . Apparently this is the major cause of gravity . Einstein under estimated the effect of time slowing in his early equations.
Thank you - that was really clearly explained. I always felt short changed by my BSc in Astrophysics as we never dealt with GR properly using tensors, just simplified using Gaussian curvature. Would you recommend any textbooks?
Hey Parth, good to see you again. I have been studying GR for the past few months but I want to have a more clear picture of tensors. So any book or video you can recommend. P.S. I am in high school, so please take that into consideration while mentioning the resources.

You can have a look at this too.. ua-cam.com/video/f5liqUk0ZTw/v-deo.html Also you can read his book too..Furthermore, since I as a High school student (from India too) was very excited by these all things, I would suggest (very friendly suggestion) you to try n understand conceptually what relativity means..At the heart of GR lies the concept of relativity..Also try reading Einstein's original book (I think its called - Relativity: The special and general theory)..It is beautifully conceptually written by the Man himself..It explains all the crux of GR really well..
@@zarvesarpit1707 Thank you for your suggestions, though I have already done everything you have said. Actually I completed Special Relativity in 6th grade only and since have been trying to understand what really Einstein sought with relativity. I am nearly done with GR as well but still have some doubts.
Excellent. Best description yet on Einstein’s Field Equations. Now we need the video on tensors!
I agree. He raised the bar on understanding a difficult subject. Einstein himself would be happy in this attempt to simplify this topic.
A tensor is best thought of as a matrix with potentially more than two indices or "dimensions"

Also you can read his book too..Furthermore, since I as a High school student (from India too) was very excited by these all things, I would suggest (very friendly suggestion) you to try n understand conceptually what relativity means..At the heart of GR lies the concept of relativity..Also try reading Einstein's original book (I think its called - Relativity: The special and general theory)..It is beautifully conceptually written by the Man himself..It explains all the crux of GR really well..
@@zarvesarpit1707 Thank you for your suggestions, though I have already done everything you have said. Actually I completed Special Relativity in 6th grade only and since have been trying to understand what really Einstein sought with relativity. I am nearly done with GR as well but still have some doubts.
@@zarvesarpit1707And yeah, Einstein's original book was really nice. My Father gifted me when he got to know I wanted to study SR.
Great experience waching it...
