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 am just a 14 year old girl with an intrest in physics and general theory of relativity over all is a great pleasure to have access to such great lectures for free thank you
a 14 year old here, thank you for this incredible lecture, very informative and wrote everything in my notebook. Thanks again!
Nice to see that the youth is interested in science and philosophy! In your generation, you have the advantage of being able to choose the best lecturers thanks to the Internet media! Enjoy your hopefully lifelong studies, which will ultimately be a tremendous enrichment for your life!
@@hannslunninger416 Thanks, i agreed with your comment and i think my generation really has everything on the internet, but also i think that my generation is also very addicted to social media and phones. At least there is still some that will always enjoy physics.
@@davidgamer5471 Young Man, I am proud of you. Keep your head straight. It's your sophistication that makes me write to you as a 32 year old. If i sense this in you at your age; I can only imagine what you will become.
@david gamer same here bro. Also 14. I want to pursue engineering in the future, which is why I am studying this to get a head start in my Physics classes. Wish you luck man
@@lyotimachida5380 Thank you very much!
I was already into physics but his explanation was like clean. Perfect lecture.
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.
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...
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
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.
I really love how this kind of lecture is avaiable to everyone who wants.
This guy is such a great lecturer. Not too fast or slow... Clear and concise...
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.

Goulg!
Ofcourse he does..he is the famous Professor Leonard Susskind..he is the first theoritical physicist who introduced the string theory...

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 CZcams where there is a wider audience.
the internet is a blessing
i am learning physics and mathematics to help explore the world and further humanity. i can’t wait to see where this will take me. ❤
Great lectures I'm so lucky to have access to them, thank you Stanford. I'm too old and broke to get another degree but love learning and this is priceless stuff.
Joe Chudleigh You're never too old.
Nothing can stop you from learning what you like :)

@Infamous Grizzly look up professor Dave ;)
@Infamous Grizzly call him whatever you’d like.. it doesn’t change the fact that he’s right & you’re wrong.
@Infamous Grizzly the irony
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.
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 🌚💪🏼
Such an Elegant Time to be alive to witness all these free Knoledge through Internet ✨
Thankyou 💫

@@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.

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.
@@ultradudexd Thats why its called a THEORY, genius
@@eragonshadeslayer1790 Theory is not about being proven. Theory is used as hypothesis or guess in daily life conversations but this is just a misunderstanding. (see scientific theory)

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.
Susskind is such a captivating, articulate speaker. Everything he talks about has me on the edge of my seat.
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
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
i half watch them for entertainment, half to learn cool things. i don't understand a lot of stuff related to this but i am slightly learning
Software engineering is easy.
@@Karuska22ps yeah easy and fun not everything should be sophisticated right
Professor Susskind is so wonderfully patient. What a great teacher.
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.
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.
The best lecture that I have ever encountered. While watching, I had all the questions that were to be answered in next minutes.
Thank you for posting this! It is wonderful to see a noted professor working!
I'm so grateful to attend your lecture, thank you, Professor!

Susskind is a brilliant lecturer. He takes the time with the basics to get the underpinning concepts and philosophy right. If you skip over these things then the advanced stuff will leave you behind.
The professor has a really nice approach to creating logical conclusions. You can follow through with whatever he says and make sense of what the nature of gravity actually is.
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
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 just want to say thank you for making this publicly available. It is a sheer joy to be able to follow the lecture.
Thank you!
brings me back to my Uni years...lovely lecture, will be following this, great lecturer!
What is the best thing about the internet? Free Susskind lectures. Thank you Stanford 🤓
Lecture is concise with a healthy amount of laymen's terms. Thanks for posting this Stanford.
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.
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.
i am determined to watch this until i understand it
Do you understand it?

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.
I love Leanord's style of lecture.Very clear & concise, interspersed with just enough humor.
1:14 'let's keep it simple', my favourite part.
Absolutely well done and definitely keep it up!!! 👍👍👍👍👍
Never get tired of watching his lectures
I do this whole class / lecture around Thanksgiving every year while at home with family. Kind of gives me a sense of relaxation.
In also watching this near Thanksgiving how strange

You made me cry Columbo Bumbo :'(
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?
Though hardly a good physicist, I think I know one when I see him. Leonard Susskind is one, more so because he thoughtfully guides us in the communicative footsteps of Benjamin Franklin. Consider this great Franklin quote:
If he would inform, he must advance regularly from Things known to things unknown, distinctly without Confusion, and the lower he begins the better. It is a common Fault in Writers, to allow their Readers too much knowledge: They begin with that which should be the Middle, and skipping backwards and forwards, ’tis impossible for any one but he who is perfect in the Subject before, to understand their Work, and such an one has no Occasion to read it. -Benjamin Franklin
No wonder so many of us are sparked here by Leonard Susskind's teaching.
What a clear, brilliant lecture.
That moment when a concept you have been struggling to understand is suddenly opened completely up by a simple off hand statement from a professor is priceless. Thanks Dr. Susskind and Standford!
Thank you Stanford and Susskind!
I still watch it even now. Thank you so much.
Listening to such long series of lectures is in fact the shortest and most simple way of getting a concept instead of the SIMPLIFIED kind of videos.
This is incredible. Thank you for posting this. Leonard is a great teacher.

Incredible lecture in the class and room
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
What an incredible teacher! Looking forward to watching the other videos now. Very well explained.
It’s so satisfying to listen to him speak.
Fascinating, simply fascinating, I watched this lecture three times and I still can’t understand a thing he said.
I have suffered for six years and I have worked towards this. Please let me come. I have looked forward to this everyday. If you forward my name, I will lose this chance.
Incredibly well explained! I'm 16 and English is my 3rd language and I have little to no knowledge of physics, but I still find this pretty interesting. And I was able to understand for the most part. Thanks ou for uploading this!

Hello 240p my old friend ..
Come to give me motion sickness again
Lmao I'm watching this in 144p
fewer pixels to distract from the information
I am a humanities students now but in love of physics as well❤. In school I never got a good science teacher and that's why i never developed an interest in physics. But as I read more and more books in all genres starting from fiction to non fiction (history, philosophy to physics and biology).... Physics became my fav subject, irrespective of my current academics i still enjoy learning physics. And I believe I do it for my passion and curiosity not because I want good grades or jobs or anything like that...... One main. Reason why I still study physics is because more I learn it more I realised how how big is the universe or multiverse and how small we are. And here we are fighting for relegion, race ethnicity....there is great quote by Greatest philosopher Socrates, "The only true wisdom is in knowing you know nothing”
I am really looking forward to coming. Thanks!
Wow...what a superb presentation...I love his precision and how he presents the Galilean and Newtonian theories of gravity in a way that makes general relativity much more accessible. I think he has tried to follow Einstein's own thinking.
Tried and failed Einstine to many speacies for.chance.is not.giberish.
It's the first time, youtube has recommended something extremely useful...!
I don't regret my life I had responsibilities and choices to me but I'm so glad that I live in an age where I can enjoy the benefit of listening to lectures by Leonard suskin for free whenever I want I can sit around for hours and just listen to the lectures of sir Roger Penrose for free I don't get accreditation for it but I don't care I love science it will never be my life that will be my passion and I am blessed Beyond reason to live at the Pinnacle of the age or this information freely accessible to anyone who wants to go learn it you won't get credit for it but you can learn it think more people would be grateful for how wonderful our time is
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.
And what’s going on with the guy at 15:01
This is the real science ! Amazing !! 1,9 million vieuws , I love you people !! Greetings from Belgium !!!
Good lecture, descriptions were detailed and informative.
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
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.
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
I just found this and absolutely love it!
Great lesson! Keep up the smart and good effort!
ABSOLUTELY AMAZING. I LIKE THIS GUY.
1st undergraduate fatality at 15:02
lmao
😂
i cant stop laughing
hahaha. I came to the comments about that sound. Thanks for clearing that up. Notice at 14:45 that Dr Susskind went over to check on it and said "eh I think it's alright"
I can't describe how funny I found this comment to be
This is pure gold.
Amazing how the Professor can explain what it is like to step off a building and experience free falling?!.....a base jumping academic, respect!!
I love seeing that a video such as this has 3.5 million views.
I love that Dr Susskind has seriously thought about Galileo throwing things off a tower.
Professor Suskind’s style is so appealingly unpretentious, like he thinks he’s teaching high school, high school summer school at that. “I get paid to explain this, your job is to listen.” He exudes the New York no-nonsense demeanor.
How funny that you have such a relatable professor that simplifies everything, but every student in the room is attempting to display intellectual dominance with big words and their own fun facts.
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
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
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.
The question around the 45:45 mark is related to the delta of R squared. As the radial demension shortens the attraction force increases and if the Delta of R squared increases the attraction force decreases.
that looks so fun I wish I was in a university already :c
highs school suuuucks
WeKnowTheTruth2012 Everything suuuuuucks if u think about it, it's all nonsense. I liked your comment btw..no hate.
WeKnowTheTruth2012 I shall see you in a few years when u'll be at uni, you will say I wish I was still at HS :)
Highschool did suck - too institutional & regimented no opportunities at upward mobility
WeKnowTheTruth2012 I felt the same way when I was in high school. I was that person who understood and thought these types of concepts and equations were fun. :P
WeKnowTheTruth2012 University is all fun and interesting until a few weeks before exams.
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

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.
Somethings never changes ,@Physics and My love for it ....
#FOR THE LOVE OF PHYSICS.
Fabulous the way he is teaching.
Whenever I go to study my note I always watch videos like this to motivate me, something about the way they explain it intrigues me and makes me eager to study/learn.
As I listened further, he got better :D
***** ... thank you Henry ... the last one was blank lol ... I WILL listen to this WHOLE vid at a later date as busy goofing around at moment ... and do appreciate it very much ... warm wishes to all in Japan ... :)
Julie-Anne Herridge Thank you!!!!
***** ... thank YOU ! .... warmly hugging everyone there .... and posting hugs with stardust smiles on the storm winds that blow here now .... which will hopefully collide with winds there and draw some of Japan's wind away , not make it worse! .... ;) xo
Happy birthday. :-)
Happy birthday !! Best wishes
Such illuminating talk!!
Loving these lectures❤️
What a great lecture! Thank you professor!
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
MIKE
Nice stolen comment from his lecture on black holes
