@TufiPepe

people like him should live forever, his passion and the abilty to communicate this passion are very much needed in this world. 
these lectures are awe-inspiring! 

@KamranRazvan

I always enjoy listening to his lectures .. amazing his understanding of the philosophy of it all.  He truly can explain the hardest of subjects to a six year old & needless to say, listening to him I always feel like a six year old.

You can, these lectures are great for getting a more intuitive feel for Physics. However to really understand it you have to read a good book that tries to explain it, do the problems. Do the Math yourself. According to Feynman actually the only way to truly understand Physics is by deriving the theories yourself, but well. That's hard. 

@thibod07

An amazing man! He explains in  a clear manner how you are short changing yourself by believing that mathematic is not for you.  Yes mathématique is not easy for every body but it does not mean to ignore it. There is still so many people that believe that they can live without understanding mathematics and this is worrisome as it leads to undisciplined way of thinking  which is a very slippery road. Yes intuition and preference has its place in this world but there is more than that. Very entertaining. Some physicians prefer total abstraction of reality when playing with their formulas so they are in many ways mathématiciens. Thank you for sharing that amazing video.

I thought I knew what high intelligence was.

That was until I watched a Feynmann video. What a genius. I love how he managed to go from maths to astrophysics, back to Newtonian physics back to Superconductivity and then interconnect it all with the energy release you get from a Sun. An amazing individual.

@timothystoutland9299

Feynman is awesome! I got hooked on his lectures years ago while driving over the road.

@TheOverThinker92

I have never been good at math or Physics but always love to watch tv shows like this. I love to watch science documentaries, physics talks even though i do not understand nothing, I enjoy watching and learning as much as possible. Few days ago I watched a lecture about gravitational waves in space, and to be honest I understood a little bit from the entire lecture.

@briank5437

I say someone should make a movie about Feynman starring Tom Hanks

@sriecewit

Man with an awesome ability to get millions seated, listening to him!!!

@MECKENICALROBOT

"one can be more stupid...." i love how real he is

@Geotubest

8:27...If I tried, in a thousand years I could not draw two consecutive circles where the starting points and ending points meet as precisely as Feynman's did right there.

@NoActuallyGo-KCUF-Yourself

This is so entertaining! I feel like I should have this on a big screen with some popcorn.

@forresterickson6225

I could not follow the triangles at about 19:26 Wishing the drawing was bigger or the camera closer.

@sampah89

In the end it is his philosophical point of view towards nature and meanings near the end of his lecture I discovered to be the most insightful thought.

@sabatino1977

I am curious to know if any of those in attendance went on to great feats of physics and mathematics.

@SherryVapors

Thanks again for posting all these great full-length vids.

@SaddamHussain-sf8hr

Honest & intellectual man

@leonsteed

He is trying to prove that triangle S24 has the same area as triangle S23 (which he previously proved had the same area as triangle S12).  Note that point 4 doesn't lie on line S3 but is slightly above it with line 43 parallel to line S2.

Triangles S24 and S23 have the same base, the line S2.  Line 43 is parallel to S2, the shared base, and therefore points 4 and 3 are the same height above S2.  Hence triangles S24 and S23 have the same base and height and have equal areas.

@jondeere5638

Not everyone's thought processes work the way Feynman professes. Faraday would be a notable exception. He performed the experiments FIRST, THEN came to his conclusions and/or guesses  based on the result of his experiments

@elif2480

How i love him so much
