We live in incredible times. With the click of a cell phone button I can view, for free, lectures such as these. Truly incredible.
Information to the masses. Knowledge belongs to no man but the people.
Marc Watt a button? you have one of those in these "incredible times"?
You really have to go to a free online physics lecture to find people with the correct appreciation for the wonders of our modern world :) thx mate
I was just thinking that
Not the smartest comment, if they charge us next time for watching a lecture its on you!
I like that guy. He completely knows what he is talking about, and in case he is not sure, he clearly says “I don't know”. I really like him.
I love people like that.
The wisest of the men will tell you they don't know something when they don't. Socrates was like that.
Goulg!
Ofcourse he does..he is the famous Professor Leonard Susskind..he is the first theoritical physicist who introduced the string theory...

Why is there always an intellectual battle in the comments of physics/math lectures? For one, these are not physics students, these are people who in their free time want to learn more about science without the rigorous math background. Two, if you are making fun of people for asking a lot of questions, you're a joke. Finally, if you really claim people are wannabes because they came here from interstellar or something get off your high horse. You're not a hipster because you knew about relativity and time dilation before interstellar came out. DO enjoy science, be happy others can enjoy science, and if you really are good at it, then HELP other enjoy science. DO NOT belittle others in a way to make yourself feel better, because guess what, you're watching this on youtube and I bet you're not formally educated on these things in any way. If you were you would see how insanely smart some of these kids are, and would respect that everyone is good in very different ways.
Only people who in fact aren't formally educated in physics come here to feel better about themselves . Why ? It's quite simple it makes them believe that there more educated it that department than they actually are , so they feel smarter . The reality is that without a rigorous background in mathematics , all those things only lead to superficial knowledge , that isn't of any use .
Here you will also see students , who have the "horrendous" desire of wanting to make a revision or listen to how another professor explains it , who dare they ? And most importantly who dare they criticize ?
+Dimitri we just want to learn, I'm 16 I can't go to university and do theoretical physics; but I love reading about them all. Is that a problem.
+I've walked the Divide i think he's projecting, we should let him be.
Everybody now back off , she knows how to project , all stand in awe of the mathematical genius or she will demonstrate her skills in Retraction , which will make Euler resurrect and kill us all .
P.S. Psychology is witch-doctoring (Feynman)
Dimitri I'm formally educated in physics and I come here. So, how does that work. Also that must mean you think the people who are attending this course are in the same spot? Get over yourself man, you can learn a LOT about physics with no math. Will you understand it to the level that someone who sees where these equations were derived from? No, but you can get a large percentage of the understanding without that, and thats what a lot of people want. If you want those few final percentage points of understanding, great, get formally educated. Thats what I want too, but DONT shit on the people who enjoy this as a passive hobby.
13 Years later and I can watch this lecture at home, in a whole different part of the world. Thank you
are you from the future ?

Susskind is a one-of-a-kind professor. He teaches in a very intuitive way yet helped to formulate the most complex theory known to man, String Theory. His lectures are so interesting and fun to comprehend.
String theory has not been proven.

This guy is such a great lecturer. Not too fast or slow... Clear and concise...
I’m thinking of this in terms of billiards. Great analysis of what is and what should be. This guy has humility that is undefined and the endearing emotion of a saint. So glad to see education like this that is available.

I was already into physics but his explanation was like clean. Perfect lecture.
At the age of 55 and with no physics qualification, I just found this enjoyable to listen to.
At the age of 67, it reminded me of my college physics classes
That is the great thing about Leonard Susskind, he describes complex ideas in a clear, concise fashion...and in an interesting way...

Try this don’t think of math as calculations rather as a language watch him explain each variables/letters and what they mean in the equation he’s writing anything you can’t connect like an example would be What is M or a Or F or let’s say for instance Vector. Google it find out it’s meaning ok Vector in physics, a quantity that has both magnitude and direction. ... It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity's magnitude. Now that you know the meaning you should be able to connect each equations, laws what so ever in a more simple way.
Honestly I’m not completely sure if I make any sense in what I’m saying but for me I understand on some level what he’s explaining and I’m just a 24 year old Mechanic with a High school diploma but a man can dream of being an Astrophysicist.
K B, you’re 57 now. Just thought you should know.

Myles this is not an intro class u might need a newtonian physics or math catch up if your having trouble
@@daviddonaldson288 this is an intro class lol. I probably would have understood it with 0 prior knowledge. Speaks to how well Susskind knows the subject.
Seamlessly weaving a drink of coffee into the lecture. Truly a superior professor.
i would do it too coffe brings a more awaking talking.
make it two coffees on each thumb, and two more In the hands. and you got it right.

Edit: wtf I didn't even know i commented this or how i got to this vid most have happened when I was sleeping hahahaahahah
@@Wild-Wood yeah yeah. What've you been told before about tryin' to summon those forces...
In the 70s I learned this stuff but in the intervening years forgot it all. Nice to be reminded. Some say Leonard Susskind is a great teacher, which is true, however, as far as teaching what is presented in this video goes, this is bog standard first year undergraduate physics, it is not rocket science, and any math or physics lecturer would be expected to be able to get across anything this simple. (I learned it in math classes aimed at physics and engineering students.)
To follow it you need to understand calculus, which is high school math, if you are planning for a degree in math or physics or electronics etc. If you understand that, the rest of what he presents just sort of clicks into place and is very enlightening, telling your (or reminding you) of things you might not have realised, but which make sense once you do. Provided, of course, you have the necessary intuition from calculus, and understand vector notation etc.
But bear in mind that this is lecture 1. It is my experience with university lecture courses that lecture 1 is always kind of remedial and just sets the scene. When he says go study Gauss's Theorem etc before lecture 2, he really means it. Because if you don't, lecture 2 will sweep you away. That's the way university courses go, at least in the sciences. You are expected to do the work, and if you don't, no one else is losing out over it.
You have to keep up, and not let any concept pass you by thinking you can gloss over it. You have to properly understand as you go, not looking back from the end of the term, because you will have far too much to retro-assimilate by then, and will have drifted through the lecture course learning so little that you may as well have been asleep.
As much as he sound like some bloke from /r/iamverysmart he's not wrong
how in the world does this guy manage his time from giving these lectures and being hitman of walter white
Ah yes, Heisenberg ...
You mean hitman of Gus Fring but yes lol

Nice stolen comment from his lecture on black holes
I’m applying to the Stanford mba since it was your idea. Thanks! I’m starting GMAT study. I’m really grateful to you and your friends for your help. I think it is fitting for 8 years of daily humiliation.
What did you get your undergrad in?
I love that Dr Susskind has seriously thought about Galileo throwing things off a tower.
Hello Stanford and Prof.
Italy here.
I thank you so much for sharing this, both for a question of learning and for giving idea about a lesson in an Usa university.....particularly yours, that is very well known
Prof. Susskind is just perfect in the role....very clear and energetic.
Subtitles are perfect too
I'm 45 years old..... I left Physics studies 20 years ago.
I'm deciding to take them back, mostly due to some of italian universities that, broadcasting lessons, are giving me the idea and the will to do it. Now also from the academic world of the Usa.....it's all just special.
Power of the web
Thank you again🙏
God bless the World

Hello Sir !
I was just randomly going thorugh comments and got this One.
I am 30y old and left my Physics studies 10 years ago due to some financial issues and lack of academic facculties here in India.
But I have been planning going back into (Physics) again since 2019
And Today I've came to know another conscious apect of getting back to Physics
I'm feeling Cherished and Enlightened inside 🌚💪🏼

@@noone-ip8qs THE CLEAR, MATHEMATICAL, INTEGRATED, EXTENSIVE, LOGICAL, BALANCED, AND IRREFUTABLE PROOF THAT ELECTROMAGNETISM/energy is gravity:
One, TWO, AND three dimensional SPACE are CLEARLY and perfectly consistent with what is E=MC2, TIME, AND what is GRAVITY. Consider what is THE EYE along WITH the fact that the stars AND PLANETS are POINTS in the night sky ON BALANCE. (c squared CLEARLY represents a dimension of SPACE ON BALANCE !!!!) What is E=MC2 is taken directly from F=ma, AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/energy is CLEARLY (AND NECESSARILY) proven to be gravity (ON/IN BALANCE); AS the rotation of WHAT IS THE MOON matches it's revolution; AS the stars AND PLANETS are POINTS in the night sky ON BALANCE. Indeed, TIME is NECESSARILY possible/potential AND actual ON/IN BALANCE. Great.

He sounds like he's in the mafia. picture with voice: "Ok you mooks, theres three laws of gravity. Who gives a shit what order they're in. Force is equal to mass times acceleration.. capisce?? Bada bing bada boom so thats what gravity is, moving on..."
Susskind having been a plumber working in NYC, and picking up that speech pattern during that time in his life, I'm sure that's what you're hearing
Jeoshua Collins I don't think I like that way of speaking.
First law of gravity is that you don´t talk about the laws of gravity

Fundamental mistake in case of Special and General Relativity where hidden on the fundamental ..philosophical purly imaginational level. SPACE IS A DISTANCE/AREA/ZONE/LENGHT/ FIELD ! /BALOON .. WHICH EITHER EXPANDS OR CONTRACTS rather than CURVES GEOMETRICALLY IN TO INVISIBLE "4 DIMMENSIONAL GRAVITY WELLS". Empirical evidence : expanding spatially ATOMS (Bohr electron jump on higher orbit due to energy=mass absorption ROBERT BOYLE !] ...expanding STARS (which accumulate matter in nucleus ..same as atom's) [evidence "death in giant"/birth spatial scattering from nebulas in to pleiads] .....and also EXPANDING COSMOS WHERE WE OBSERVE GALAXIES MASS ACCUMULATION IN NUCLEUS [uniformity, direction of expansion, acceleration all explained] Basically "space also has to be made out of something" ...and this "something" is HOT, DENSE, HEAVY NUCLEUS = PLACES OF ENERGY CONCENTRATION

Professor Suskind & Feynmann are people who can lecture about something in such a way that the beginner student understands while the advanced student gains deeper insight.
this is pure junk. gravity is an unproven theory that has no basis in reality space is not a vacuum, there is an aether. the speed of light is the same coordinates as the pyramid of Giza.
@@Hey.bekind777y 😂😂😂
@@Hey.bekind777y If gravity is an unproven theory, then what keeps us in orbit with the sun? what keeps our arm in the milky way from separating from the galaxy itself? how would you personally describe entropy?
Also, with the pyramids of Giza, that's only a bizarre (and very obvious, upon inspection) coincidence that arises from the speed of light being measured in SI units, meters per second. The speed of light used as a coordinate (only the north coordinate, 29.972°N) can correspond with the pyramids, but it can also correspond with anything on that coordinate line (think of it as like a ring around the Earth where you can place the coordinate). We could also choose the coordinate to represent the spend of light to be 2.99792°N (which would closer to the scientific way of writing the speed of light). We could also change the speed of light to natural units, in which case its respective coordinate would only be 1°N. We could switch the speed of light into feet per second or inches per second and get different results too for the respective coordinate.
I hope this helps you see why that particular conspiracy theory is incorrect. If you have any questions about this feel free to ask :)
So he's saying Earth is flat and there's a dome over us cannot measure a round surface using gravity impossible
they have true understanding of their subject, something that can only be said of a very few people in the universe
I really love how this kind of lecture is avaiable to everyone who wants.
i started listening to this to make my dad think i was in a school lecture at first, but then i ended up listening and paying attention about 20 minutes in LOL
i love simple, straightforward lecturing like this: no reciting super drawn-out textbooks and making you regurgitate it, just explaining it in layman's terms and using examples you can easily imagine!
What about this is straightforward?
Leonard Susskind understand much about Black Holes better than Stephen Hawkings. In fact, Stephen Hawkings accepted defeat and gave Leonard Susskind flawless victory to use Mortla Kombat classification of epicness and ownage. This is no ordinary university lecturer, this is one kick-ass astrophysician.

hard to deny that. lenny got more brainpower than hawking
I am one with the force, the force is with me.
Legitimate questions are fine. Questions designed to show the teacher how smart you are drive me crazy.
yes, and it is not the only video with that. Dr Susskind must learn how to shut up some people
Agreed
Those questions clarify the subject, it helps looking from a different angle. If you don't see the benefit of such questions i don't see the point of having questions
turin turamba It interrupts the flow of information. The professor has worked very hard to format his approach to flow logically, and these questions break up that flow for everybody else in the room. Save your questions for the end. Be respectful.
@@markg7963 if you are a true scientist, especially theoretical physics you can talk for hours on different topics and then comes back to precisely where you left off as this professor demonstrated several times. Fresh minded students don't have that, and most ideas come spontaneously at the moment. If you have questions at the end it is pointless. At work I've seen too many meetings with silent questions at the end so im tired of those. And science is not about knowing or not knowing, it's about learning so no matter the question it is worth asking
Amazing how the Professor can explain what it is like to step off a building and experience free falling?!.....a base jumping academic, respect!!
It's my pleasure to add comment #4,000. Susskind is a joy--not only incredibly brilliant, but patient, funny, and beautifully clear. Such a gem. And how great to have these lectures available free of charge for anyone who's interested.
that looks so fun I wish I was in a university already :c

It's late, but this playlist is fascinating and I'll make sure to finish it. :) Thanks, Stanford University , for uploading these lectures for those of us who can't be there in person but are curious nonetheless.
Just wanted to express how thankful I am for these lectures. I've watched many of Mr. Susskind's quantum mechanics lectures that I have yet to finish. I work as a software engineer, but I've always had a soft spot for physics and math. When I study this stuff, I feel like I'm playing.
No problem

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

We need to read the board, but Stanford gives us a 240p quality video. Brilliant.
I watched his lecture over ten years ago on iTunes, along with several other lectures from Stanford. I am glad they have been brought over to RUclips where there is a wider audience.
1:01:56 he is going down..
very few liked cause very few understood......
they haven't arrived to relativity yet ;P
100%. This is great

I wish i my analytical geometry teacher was like this professor here, he explains is so simply that basically a high school student can understand it.
Most of the questions were silly, and things you should know before having seen this lecture. Clearly these students have taken up to vector calculus, and multiple physics courses. Questions like why the force of gravity is negative, or how the length of a vector in a vector field relates to the strength of the field at that point annoyed me since they’re fundamental concepts of topics you’d learn in the prerequisite courses before this class XD
tldr: their questions were about things they should already know/ are somewhat obvious
thanks to the RUclips sorting algorithm to recommending me this video lol
Over 1 million 300 thousand people klicked on the right video. Good.
Yet 188 managed to not like it.
Abhijat Verma Who cares. They're gringos.
+DeuceGenius People who don't speak English don't come to an English language website, make an account and then watch English speaking videos.
shouldn't be watching a relativity lecture if you do not know how to spell!
Nah dude it was on the left, why ¯\_(ツ)_/¯
This guy looks like he could benchpress a truck.
A million trucks at the same time, but in a thought experiment, while reciting prime numbers in between sets, without pause.
@@Jamie-Russell-CME underrated
very true
It's the first time, youtube has recommended something extremely useful...!
Is it just me or does he sound vaguely like Christopher Walken at times?
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
I'm sorry for this, but as I listen to his lecture, I can't help but hear Christopher Walken's voice.
FLUCK-too-a-shuns...Need I say more?
This comment is priceless!
Lol yeah he kinda does; that's awesome!
New York accent.
Garrett Grantham Christopher Walken probably makes more money and probably doesn't do this mathematics in his spare time. so there is still hope for some of us
IS TIME THE CAUSE OF GRAVITY ???
No gravity is different from time .but gravity depends on time if time stops gravity stop working in other words gravitational effect stop working
@19:00 what is is trying to say is the force of acceleration due to gravity is uniform(on each atom etc) and therefore not detectable without some other frame of reference (standing next to the leaning tower and watching something fall- or vice versa)
Yeah, I learned physics in Stanford.
I'm proud of you even though I don't know you.
Didn't understand a thing. Damn, I feel so stupid.
+ Learn a bit of calculus and then this will make sense. Just one question; do you know why F = ma? (its a convention).
*****
You can't be serious? This lecture jumps right into Multivariable Calculus.
I would recommend looking into more general particle physics and/or general to advanced calculus if you are do not understand this. It is definitely not trivial in any case.
Start with some basic physics videos instead, this is after all about General Relativity so you know it is going to be like climbing Mount Everest later. He starts off slow but accelerates rapidly.

Maybe he knows a non-calculus way to deal with curl and other concepts associated with relativity.
15:02 when you understand you can't understand physics

If you are not able to explain it to someone who is not at all familiar with the subject ... you do not understand it yourself.
The good professor is able to explain it to someone who is not at all familiar with the subject !
It’s 2am and I really need to sleep.
An hour and a half lecture on Einstein’s general theory of relativity? Sleep can wait.
I've watched these lectures spanning 2009-2012, and in most of them there's some guy coughing his lungs out!
David Ruiz-Tijerina imagine now in corona Virus haha
Professor Susskind,
I have study your lectures in the general relativity, they are very good lectures, I thank you wholehearted ~ Thank you very much ~ Professor Susskind ~ :)
17:40 I’m confused I think, what happens if you throw a ball up while your free falling in a gravitational field. Won’t the ball go up and gradually stop a certain distance from you. Where as if you not in a gravitational field and floating in space the ball will continue to go up infinitely.
Any clarification would be great, thanks.
NYC represented! Glad to see Susskind hasn’t lost his northern drawl
great professor Leonard susskind
I love seeing that a video such as this has 3.5 million views.
This is great! With my grades, I wouldn't qualify to sweep floors at Stanford, so thank you for posting this so less academically inclined individuals like myself can at least listen in on what smart people discuss.
Acedemic success relies on a students motivation
Grades don't much if anything to do with intelligence and the people at a private school like Stanford aren't necessarily smarter than people at a CSU. And in fact, the pain and theft inflicted and unleashed upon us after hundreds of years of Yale and Harvard grads suggests that you definitely shouldn't idolize these private school grads, in fact you should be skeptical
In Romania we learn about Gravity in 7th grade at Phisics Class.
In U.S you learn about Gravity while at Cambridge
Period.
I hear ya but they taught you wrong.. : (
I was lost when he said, write your name at the top of the paper
What a teacher!!
+Michael Loughrie I know right? The other series on physical chemistry is fantastic too!
Saint :D
+Michael Loughrie he is OK, Brian Greene is much bettter
+FantastyckplastycK Brian Greene is a science advertiser & an annoying one at that, Prof. Leonard Susskind is one the great scientists of the modern era & one of the co-founders of string theory.
Nameless Paladin well whatever, i much prefer greene or muller of caltech or even krauss for that matter.
"Everywheres." I love all these California professors from Brooklyn/Bronx. Ribet, Susskind, Feynman. Who else? They're taking over!
came on just so id fall asleep
you dont notice at first but i was slowly gaining interest.
felt like i was learning something lol
props to teach(found him engaging)
an average person can actually learn something here
im here because i regret taking physics for granted back in my highschool days and not pursuing astrophysics. just making peace with myself and watching this amazing lecture 😭
After 14 years we find a video that help us😢😢😢😢😢😢😢😢😢😢😢😢😢
52:00 "Bill O'Reilly... please listen to these wise words!"
ROFL Tides go in, tides go out. You can't explain that! HAHAHA
This lecture series is fantastic. When I took physics, general relativity was a side topic, quantum theory was the main event. Over the years, I've dug through references like Dirac, the huge Misner, Thorne, and Wheeler, others. Each one brings some new illumination. And this lecture series, starting from the most basic constant field of acceleration, has brought out some fundamental principles that I never before realized...just basic, like why a vector field derivative may not be the same in all coordinate systems. (Because the coordinate transformations themselves yield non-zero derivatives, which need to be removed using the Christoffel terms). Once I finish this set, I'm definitely up for others. Thanks Stanford.
From Galileo’s universal force to Newton’s mass-driven attraction and Einstein’s spacetime curvature. The persistent question remains: What truly defines gravity?”
Galileo - “Gravity is a force that acts on all objects, regardless of their mass.”
Newton - “Every particle attracts every other particle with a force that is proportional to the product of their masses…
Einstein - “The curvature of spacetime is directly related to the energy and momentum of matter…”
Whether it is “their mass, product of their masses, or momentum of matter” matters. It simply cannot be done in three different ways and be correct!
Susskind ignores this in his statements at about 14 minutes into the lecture. Carl Sagan would have called this false premise a "Bamboozle".
Im gonna put Stanford as my education background on my resumé
Gotta have a degree
@@ethanvillarreal5766 i know it was a joke
If I ever, ever manage to make enough money to go to Stanford, I want him.as my lecturer. Most physics lecturers drone on and sound bored, but he's obviously passionate about it and makes it interesting. I don't really understand much of this, I need to do some basic physics again and catch up (I'm actually doing Law, but interested in physics and computer science).
I was born in a great time, time where there is actually an effort for Open education, education that you can spend your own time and effort on, and because of that, you'll do better (I assume) because it's not being forced down your throat.
Thanks to OCW projects I don't think I'll ever quit learning.
did you get in
Y’all are here to learn. I am here bc I can’t sleep. We are not the same.
The positive effect of RUclips: Highly intelligent lectures are free!
Thank you Mr. Susskind, The subject is very difficult but your approach is very welcome. I can follow what you're explaining. I learned this subject years ago but had some areas that left me a bit confused. Your explanation is better for me to follow. So thank You very much.
I have no idea of what you were talking about but cool i guess
It is easy to understand theory of relativity , but quantum physics(mechanics) IS very difficult to understand.
Imagine being a highschool student and viewing these for fun
*laughs nervously*
I pointed to nearly flat universe model from some old lecture from Lisa Randall or Brian Greene while he built the only building in the small town
High as fuck
I would certainly like to see a lecture by some of you who are so critical of this lecture. I bet it would be just great.
nidurnevets that's the spirit. sucking up for that good grade. do what you need to do
Here you go: www.flight-light-and-spin.com/relativity/gravitational-waves%2Bgeneral-relativity.htm
I know right. This guy explains it amazingly.
Response videos came and went like a fad, but for once if LS could only stop pacing the floor needlessly, that would help a lot.
You can write what I know about physics on the back of a postage stamp but I love watching Dr. Susskind's presentations. Thank you so much for uploading them.
Incredible lecture in the class and room
15:01
walruses love GR!
Lol xDD
Heard it came straight here looking
Dr Susskind's Theoretical minimum series is excellent although I don't yet have the math skills to absorb it all. but going to school this fall so will be learning the math.
Hello, I just wanted to say, this lecture is one of the BEST I’ve heard! It was really nice having myself take notes and have everything add up and make sense. Thanks!
Also, I may be 12 years late to this lecture…
Lies again? Big ego
If you close your eyes, sounds like Peter Griffin 😂.
I bet this guy could do a great Pacino impression
This is so clear. I understand the Gaussian theorem and Newtonian gravitational theory much deeper. I also understand what is divergence is and how it is applied to gravity.
Is the homework set for this course available? I've been following along but without trying some problems I'm afraid I'm not getting much out of this.
Lol
I’m glad I woke up to this after leaving RUclips auto play videos in my sleep
