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!

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.

are you from the future ?

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.

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. By Frank Martin DiMeglio

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

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

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

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"

You made me cry Columbo Bumbo :'(

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
