@@imyasharya They are related because the Tensor cores perform matrix multiplication at a very fast level to make GPU's effective. If a bunch of tensor cores are each doing a form of matrix multiplication, collectively, one could say they can perform tensor multiplication because tensor multiplication is ultimately one form of multiplication of a specific set of matrices. However, I don't know if that's why NVIDIA calls them tensor cores or not.

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! 🤓

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.

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.

@Parth I'm familiar with the expansion of these equations into the partial differential equations but I'm not sure about the notion of space-time. Based on lectures by Susskind at Stanford i perceive space-time as a coordinate transformation rather than an object, as most main stream content depicts. It is a way of getting your ant to move through a curve by simply saying move forward along an axis, however the axis is itself curved. The notion that space-time is an object like the rubber sheet the massive object sits on is misleading, and implies that space and time are objects that are changing due to the presence of matter and energy.
