Physics 10 - Lecture 21: Review Session

[keepitrealfun]

love this stuff , no hard boring stuff

[headybrew]

so If I've got this right:

c=299792458 m/s

earth's orbital v = 29770 m/s

beta=0.000099302031

gama=1.00000000493045 (I'm ignoring significant digits...)

So for every billion years on earth, the sun ages 4.93 extra years.

Does anybody want to check my math?

Oh, and THANK YOU Professor Muller and Berkley for these videos!

[sergheiadrian]

@headybrew Yep, that's right. I did the calculations myself.

[solntom]

Professor Muller, thank you for making these brain teasing concepts so comprehendible truly captivating!!!

[Psyclaws]

I've been watching this series for 21 lectures now. I'm absolutely captivated, this guy is awesome! I have to ask a frame of reference question Does the fact that I just noticed that Muller only has two shirts say that I am shallow for noticing, or mostly oblivious to superficiality given the fact that it took me 21 lectures to notice?

Either way, THANKS SO MUCH for posting this series!

[BenG549]

Im doing the same, im working my way though these videos and i to am captivated by the amount there is to know about the way the word works around us. To your second point, i think i noticed he wears the same to shirts within the first 2 or 3 vids, only because when you scroll down to see what topics are coming up i noticed he looks the same in all the stills next to the name of the video! i think what is important tho is that this series of lectures has exited a new found love for science!

Psyclaws: re your question re his shirts: given that he has lectured about quantum physics, and etymologically quantum is related to quantity, perhaps he has many of the same shirts back home. ∴ in our reference frame he seems to be wearing the same shirt every day. But he may have many of the same shirts back home (which we don't see) and so in his reference frame he is wearing a different but similar shirt every day. A new theory of relativity perhaps? & I agree, I like his lectures vm too.

[Eniacbc]

@Psyclaws That depends, did you notice that before or after watching the videos? xD

[bmikesci]

The average high school student should be able to take this course and profit greatly from it. General science teachers, if you are not covering this material - more or less in this way, you are not doing your job. This country will spend billions of dollars hiring science teachers who don't know what they are doing, when the nation could be producing high quality courseware like this for just a fraction of the current cost .

I think that Prof. Muller got a little bit wrong with that tachyon and free will thing. To use a tachyon gun you must travel at the same speed, faster than light. ''Order in which events take place gets reversed when measured in different frame of reference.'' So from your point of view you pulled the trigger and someone died, but from the point of view of people who are not moving faster than light, death become before firing the shot. So you are not going against your free will...

[tenjugney]

i don't know  know how curved space time squeezes or streches the matter...

[thelemur]

getting a bit abstract. But good stuff. Muller is a quite good lecturer. I only have few comments to some of his explanations, but in all this is a great lecture. In my mind this kind og stuff should be taugt to much younger classes, to get them interested.

[SPRMSSVBLCKFOTSEN]

i feel bill hicks would appreciate guys like this

[themachinegunn]

would have

[cgrade0815]

Nice one.

[Charlesincharge42]

Thank you Prof. Muller!!

And speaking of 'Future Presidents' here's hoping the next generation of politicians is a little better educated and more noble than the current crop of half witted over dramatic gluttonous thieves.

[Gerardoratx]

this is really awesome. thank you Professor Muller!!!!

[rabmunch]

This guy is great! Excellent for non-physicists who wish to become familiar with some of the concepts of relativity.

I am tempted to write him an email and thank him for his contribution to YouTube.

It is only an introduction for non-physicists and must be judged from that "frame of reference".

Thanks Doctor Muller!

I hate when teachers bring up their own views on things because as hard as they try to be 2 sided it just doesn't happen. They should be spending more time on teaching facts then sharing views. That goes for nuclear power, the tesla roadser and all else he has talked about. Teachers have more power of influence for the majority of people that just listen to others rather then think for themselves.

This is great. Thank you UC Berkeley.
