Tibees hi I am a. iitjee aspirant from India its my request to you to please review the book CONCEPTS. OF PHYSICS - BY HC VERMA he is a professor from iit kanpur thanks
"When I meet God, I am going to ask him two questions: Why relativity? And why turbulence? I really believe he will have an answer for the first." - Werner Heisenberg I have taken the courses in both subjects and studied them at length so I can say that although Physics is no less than magic itself and turbulence has to be it's greatest trick. We may witness the incredible advancements in quantum mechanics in our lifetimes but we may never see the true solution of turbulence. There's just no competition against the theory of chaos.
Relativity is an optimisation for a simulation of a big universe. Without relativity, the collision detection algorithm (for all moving particules) would eat all the processing power. With relativity, since the longitudinal space dimension is compressed, the volume swiped by the particules becomes much smaller, and therefore a lot less collision tests have to be done. Of course, the consequence being the relativity of time adds a complication, but at least, it doesn't penalise the particules moving slower in the simulation. As for turbulence, they're the friction of fluids. Let's say that without them, it would be "funny"...
Mathematicians: "A topological space where every point has an open neighbourhood that can be homeomorphically mapped to an open set in an Euclidean space." Physicians: "A possibly curved space which, in small enough regions (infinitesimal, really), looks like flat space." Lol 😂😂
That is the definition of a manifold that general relativity textbooks use. But if you're writing a short document meant to convey intuitions why go into those technicalities? Who in your target audience does that help?
I did my bachelor thesis in semi-Riemannian geometry and how it models GR. Fascinating! When you get to compute the Riemann tensor coefficients and the Christoffel symbols, you do see why it's not for the faint of heart.
Hi Tibees. You've done a good job of explaining this topic at a basic level. No excessive off-putting formality and enough insight to make me want to look into it further. The mark of a good teacher.
I like these little clips, I may not head out and start consuming every text book I come across to further my understanding of this but I feel like I leave with a little tiny piece of knowledge which usually turns into an idea that always seems to connect to something else...so thanks Toby
Been trying to understand a bit of GR for a number of years now as a part of my hobby/obsession with Astrophysics. Susskind is great but it's all math. Currently digging in to tensors, again, getting further this time. My white board is currently full of vector definitions, so this was timely and enjoyable, thanks.
I can't quantify the degree of admiration I have for your efforts to explain mathematics and physics to the many people who are less familiar with these incredibly important subjects. I believe one of the primary obstacles for most people as they try and comprehend more abstract concepts is their limited ability to conceptualize beyond physical reality. Visualizing 3 dimensional space isn't too difficult, but most are challenged as you try and explain the fourth dimension, for example. I think it's a iterative process that begins with a good math skills, and right there you've lost the vast majority.
"Exploring Black Holes " is a great book for beginners. It just uses basuc calculus to develop GR.. Once your appetite is whetted , Hartle take you thru a breezy introduction in his book Gravity. By third or 4th year , once your mathematical abilities are up to the mark - the ability to manipulate tensors - you can start reading more serious books starting with Sean carrols books
YES!!!! FINALLY SOMEBODY SAID IT!!! It's not waves, it's not quantum and it's not thermo. General relativity is the single hardest and most un-intuitive topic I had to learn
GR was my first big kid physics class (well, after my astrophysics dynamics course) and it was probably my favorite. I suck at tensor math but it was really cool to learn about and now I wanna go over all the stuff I learned because of this video.
Well i liked physics till i was in 10th grade but being an indian 11th grade jee aspirant made me hate it its just mugging up😑😑😑 wirting and memorizing not even giving time to think something new ... Ur vids help me to keep my interest
I would highly recommend A General Relativity Workbook by Thomas A. Moore for anyone interested in trying their hand at GR! Love your videos as always :)
I'm Douglas Bahati aged 17 and I'm very good in General relativity ,special relativity and all bizzare laws of quantum mechanics and also genius in computer science and quantum computation
People think quantum mechanics is the hardest physics topic. Even I thought that, but after taking both courses, I found that the mathematics and concepts of general relativity and cosmology are much more difficult.
At 6:01 you say "at some situations you won't be able to make the difference". Isn't it supposed to be "at all situations" (which is what makes it the equivalence principle)?
Your locked objects in a safe can be removed without using any dimensional manipulation or affecting the safe. Neutrinos have no electric or magnetic field so that they pass through the empty space between "particles" . If the objects in the safe had it's electric and magnetic fields disabled it too will pass right through the safe like a ghost but it still has form because it's atomic bonds hold it together.
Honestly, I like the coordinate-independent view of differential geometry that mathematicians use. It gives a much clearer understanding of curved space/spacetime. Unfortunately, it requires a lot of formalism that doesn't have much to do with physics, so it's understandable why general relativity is taught the way it is.
Perhaps there's a better formalism but since the geometric description is used pretty much everywhere in advanced physics, I'd say it has something to do with physics if we think about it in terms of descriptions.
@@RalphDratman, it can be really difficult to distinguish the difference between "zee" and "cee", and replicating that difference can be almost impossible. Therefore I'll continue to say "zed", so people can understand what I mean.
@@TheGlassgubben That seems logical to me for international cooperation, where various ways of speaking English are a significant factor in understanding. In the US I have never seen any confusion of that nature, perhaps because our dialect of English makes "zee" and "cee" quite distinct. For myself I am perfectly happy with either pronunciation.
@@RalphDratman, yes, through American media it's quite obvious that you have no issues with misunderstandings in this regard. The reasons for my difficulties is probably the lack of a difference between the "s/c"-sound and "z"-sound in my native language.
This was very enjoyable. I love your pacing. It's followable for the topic (though I will add all I have had a Modern Physics class only before this). Nicely done.
I have put this on save to watch later. I have an book written by Albert Einstein for graduates on this subject and It is very readable. Look forward to Toby on this topic later.
Me looking at the title: "Idk, I don't think any area of physics is particularly difficult, you just have to practice." Tibee: "General Relativity" Me: "Ah yeah, fair enough." I haven't taken a proper GR class, and probably won't since I'm into experimental physics. But I took Differential Geometry, and that was easily the least I've understood from any class I've taken.
Toby : Nice job ! Don't let folks get you down . If anyone has an understanding in logic and math they should be able to follow your e-mail. Great job on black holes and quantum physics comments. Might want to re-suggest Tyson's books as well as Kaku's and Malik's for basic understandings of the universe,cosmology, and hyper-space.
I'm not sure if It's appropiate to make a question here, that said... Once I read that after GR, gravity is not a force anymore but a space curvature so that you now can't say that an object is "attracted" by gravitation because the object is simply following the space curvature. Are those affirmations correct?
You explain everything so clearly and nicely! It’s so easy to follow and understand, even for these hard topics. Maybe you could post more videos to follow along it more specific like calculus? Sometimes Professors don’t have the time or patience to teach this slowly and clearly. Anyways, just an idea:)
why is it considered impossible to create a magnetic bubble in a vacuum, if an infinite number of magnetic sources are allowed ? (magnetic bubble = a region in vacuo where the magnetic intensity inside the region is greater than the magnetic intensity outside the region.) this youtube channel is the best, your delivery is perfect. you make me into a mind reader. you would earn a good living as a hypnotist, erasing mental blocks from students minds. thanks
- Oh... - They've looked at electromagnetism in GR - Now how about revamping QM with determinism (maybe pilot wave) and analyze the informational nature of matter and spacetime. - That's a little like reaching out to each other, no? Maybe I'll just goof around after that
A few years back I binge-watched Susskind's lectures and almost understood quite a lot, but I think I'd have to repeat the whole thing again now as I seem to have forgotten most of it ;-)
Here's my recommendation: Start by reading these books in this order 1) open.umn.edu/opentextbooks/textbooks/book-of-proof 2) www.goodreads.com/en/book/show/8295305-a-book-of-abstract-algebra 3) www.goodreads.com/book/show/264543.Abstract_Algebra 4) www.goodreads.com/book/show/116418.Topology 5) www.goodreads.com/book/show/208761.Introduction_to_Topology_and_Modern_Analysis Then watch these lectures ruclips.net/video/7G4SqIboeig/видео.html
i'd go with topological quantum field theory as the hardest, also since gr is teached to bachelor students of physics and math (sometimes) but tqft is like only for masters or phd people
"Hard" is a Theoretical Limit type topic? In which case, the "No Boundaries" hypothesis applies and the natural visuals of perceptions is inverted, "hard" is where we are, floating in software.., because you can go against the Observable Eternity-now Interval Conception Superposition-point Singularity Perspective Principle and construct a reverse cycle mathematical proof of concept, Disproof of hard fact, simultaneously here-now-forever. In support of the two great Physics Teachers mentioned, Prof Susskind's style is to disassemble the hard facts and inspect the properties of the components, a style that is appropriate to "learning by doing", and because hard facts approach significant limits of understanding +/-, then it's possible to imagine merging those probability abstractions into the Big Picture, but without the kind of realization we have come to believe is Mathematical, and believe to be self-consistent truth. So if all Einsteinian style Relativity Theory is devised mathematical from the observation of EM spectrum data, and WYSIWYG here-now-forever phenomenonological localization of hard facts, it's possible to say how those facts are real in their own terms, not so much in Pure Dynamic Mathematics of "Something in Nothing", Actuality of "mathematical" Time Duration Timing Modulation Mechanism. The actual truth/nature of Time as sync-duration connectivity logarithmicly positioned Superspin-spiral, wave-package resonance integration looks like the EM picture of an explosion, but actually self-defines in Dynamic QM Superposition-pointed Singularity holographicly/projection-drawing, of apparently purely logarithmic mathematical origin that in Math-Phys-Chem and Geometrical proportioning-positioning is composed of sync-duration Time. Consequently, we rely on empirical beliefs modified by Math-Physics (QM-TIMESPACE) based continuous observational information refinement, which is termed "Theoretical", due to the innate uncertainty of e-Pi-i omnidirectional-dimensional, logarithmic interference positioning, factual inputs. Prof Suskind supplies the refined facts, Prof Carroll paints the Big Picture in Theoretical effectiveness. "No one is right if everyone is wrong" in degree, because of innate uncertainty in continuous cause-effect creation, circulation pulsed re-evolution, no matter how precise Numerical Mathematics can pinpoint phenomenonological localization, the mechanism of continuous cause-effect positioning is inherently metastable. It's hard to believe anything at all under the circumstances, and makes Cultural Evolution propositional, ie Political, and reliant on trust in forward thinking. WYSIWYG.
What would be math prerequisites to prepare for tensors? I understood the Susskind parts about metrics but when the partial derivatives get all mashed together on the board I get so lost.
schwarzschild is a composite word but the words are schwarz-schild so its NOT pronounced like "child" in the end but more like "chilled", maybe look it up idk. Love your videos!
This was so interesting! You should make more videos about GR and just working through some problems to show the math involved. I would be very interested in seeing that.

Un topico dificil, conexiones,covariante, tensores, seudo-tensores, derivada covariante, subir y bajar, distintos tipos de formalismo, lagrangianos (materia + gravitacion), distintas coordenadas (E-F, kruskal), geometria diferencial (variedades diferenciales, 1-form,2-form, producto exterior, producto estrella,espacio-dual, fibrados,espinores),teoria linealizada (ondas gravitacionales, gauge, coord.armonicas, quadripolo),curvatura, escalar, ricci,demostraciones,identidades de bianchi,affinidad,etc,etc. De verdad un curso bien duro.
Did Sean Carroll ever make it to Australia? If so, did he ever get out?
