Physics 10 - Lecture 08: Review Session

[marcarmstrong88]

28:00 in he was right about that part of the DNA being found to do something! :)

[bloggycreek]

Thank you Professor Muller. I appreciate people like yourself, Richard Feynman, and Carl Sagan who bring science education to the public. The world needs more education. Thank you and UCBerkely for providing these lectures.

As a historical social footnote, this educational lecture has

32,900 views after 4 years, while the video song Party Rock Anthem has

227,275,503 views in six months. @:<

[stonedogre]

would anyone happen to know what film he had his students watch?

[eugenepl]

Listening to Dr Muller you will get Wowed at each and every lecture without fail!

[gethoserri]

Ungreatfull and disrespectfull fucking students, they should get down on their bare knees and suck that brilliant mans cock!.

[TheJmz1983]

brill got me from the minute he spoke

[adraim69]

I don't think the increase in quality of living has as much to do with the decrease in population growth as the liberation of women does. Without fail, when you take a countries female population, and educate them, they realize they're more than annual baby machines. economic prosperity shoots up because you have a large work force and more consumers, population growth goes down because fewer women have children.

[numberJ5]

He made me laugh out loud when he said "Here I am Osama Bin Laden. Yes these Americans will have an increased number of cancers in the next 30 years and they are individuals and they will die!". haha.

here's another comment

What's your point

(if it is what I think..how do you think people come to these equations in the first place, by "not understanding it"?.. :P )

[peterockenhauser]

Professor Muller is Awesome! I love listening to him speak.

[trident3b]

2,4,8,16,32.... 1028?.. it's ok, only nitpicking... he meant 1024...

[asimplecapsule]

Yeah he makes a bunch of little errors like this. But generally I've found his lectures very very informative. Very grateful to UC Berkeley for putting these up. Top level education should be free for everyone.

[trident3b]

agreed.

[ibreakkidslegs]

he was taking into account the average interactions between neutrinos and dark matter that produces 2 neutrons....... -_-

[bmikesci]

I remember watching a cop show about people dying after buying ill-made homemade soap. Of course the show was sponsored by a soap company.

[bmikesci]

If I were a PR guy for the electricity industry, for nuclear reactors for example, I would spread fear about natural gas too. I'm not saying that Prof. M. is doing this, but one should consider who pays him and what are his possible motivations.

[bdhcarbon]

Does anyone know what the name is or how to get the video the prof mentions he shows in this class?

[Meddlmoe]

hey! you spelled prediction right!

[stelivo1]

lol very funny im sorry for being dyslexic

[Skurgefaust]

im already on lecture 8 lol  gonna watch them all wonder how much i learn lol

[Focusb4ufire]

i like chat about biology, chemistry and physics in one lecture. they are all linked and its nice to see examples etc. i prefer this kind of lecture to pure physics, learning one science confines you within 4 walls, a bit of it all allows you to understand the world far better.

[TheFerruccio]

This is very much like how every physics class should be. It's not about rote memorization and learning how to do certain problems. That's what the textbook and homework is for. That's what visiting with the prof and meeting other students is for :)

The mistake many physics professors do is just dive into the numbers without sufficiently explaining what's going on. You end up chugging numbers without knowing what you're actually doing these calculations for!

[NickHeyeskate]

1024, not 1028

[SPRMSSVBLCKFOTSEN]

these lectures are ideal if like me you study in your own time because any physics internet course your mailed is often only text with equations, which i find are much more applicable when there is a good picture of the concept already instilled, these are just that bravo!!!

[tekproxy]

This really isn't like a physics class. It's like a "Really Neat Stuff" class. It's exactly what I want to learn.

[mavadd88]

this physics class is not like your regular physics class. if youve watched another lecture, youll notice that there are absolutely no calaculations. He basically just covers science topics and discusses them and lectures on the basics of them. I think he also gives essay tests...so definitely not your typical physics class

[nonxcarbonx]

I don't really think that all of this belongs in a physics lecture.

[Beatsmith2005]

Agreed. A little too much al-qaeda talk for my liking. More science please?

[wrdeboise]

Yes, a very loose survey-type class--Mixing in biology and physics. At first I was confused by the lack of focus. But now I kind of like the generality of the topics introduced.

[pjholl]

He mentions on more than one occasion that 512*2 = 1028?...he means 1024

[TheJerm78]

I noticed that too. He doesn't seem to care much if his figures are entirely accurate, only that they're in the "ball park."

[roblow12345]

If radiation truly isn't as big an issue as the man says, then why are big parts of the Ukraine STILL uninhabited??

I mean, what good does this do for the Ukrainian government?

[tuxmant2]

If done RIGHT it isn't a big issue. Go back and watch the lecture before (Physics 10 Lecutre 07) in the old USSR the Chernoble (sp) reactor was built so wrong it seems like the equalivant of pouring gas directly into your engine by hand and hopeing the car remains safe.

[roblow12345]

Well, to my knowledge there wasn't anything wrong with the plant itself.

The incident ocurred when a TEST was done wrongly and the whole system overheated.

[roblow12345]

But the fact is that Prof. Muller claims that there should be no danger in living in the chernobyl-disaster zone.

If he's right then my earlier question still counts!

[Dentiq]

And there are people living in the Chernobyl area, but its mostly small villages rather than sprawling industrial towns. And with respect to the radiation they use Geiger detectors when handling allot of their food.

[somnolent49]

The plant design was horribly unsafe. The wikipedia article covers some of the reasons. Look up Pebble bed reactors to see some of the modern, safer reactor designs.

[roblow12345]

Thank you very much, i will certainly do that!

[roguepink]

The entire set up of Chernobyl was ridiculous, think - take a reactor make it 8 times as complicated as it needs to be , dont surround the reactor in the respective layers of steel/concrete, then ignore all safety procedures.

That type of reactor hasn't been used in any country but former USSR, why ? cos its shit

[yetidetective]

you forgot to pack the nuclear material in charcoal. that part is very important.

[djpupeiis]

because of radioactive dusts

[flach99]

you should reall watch all of the lectures. PAY attention to what the smart man has to say, because he has already covered your first question. the second question of yours is really obnoxious- what good do you do you lousy hippy?

[curvand]

I've been though every lecture up to this point and i have learned a lot of new things... even though i hold a Bsc in electrical engineering... never too old to learn and Muller is amazing...

[Zevcollins]

I've been through every lecture up to this point and am yet to learn anything new - but it's nice having these concepts put into some context and Muller's amazing.

[DangerDave67]

Am I the only one who's taken aback by the way the students start getting up and walking out while the professor is still talking? If I were in this class, I'd be the one asking questions to keep him talking as long as possible. Those kids don't realize the opportunity they're missing.

[girocraz]

Thats America, students dont greet teachers. Why, where are you from

[heekimsang]

@DangerDave67 Maybe they noticed the cameras were recording everything and decided they'd watch it later

[cbruer]

zetregue, please show me the analysis that shows nuclear power is "uneconomical." And please let that be from a reputable source, and not some homemade website. The efficiency of solar is not quite there to make it a good candidate, and wind provides a paltry amount of power.

[zetreque]

It's only greener as far as the air is concerned, every type of energy has a counter side to it, law of conservation, just a matter of which down side best fits into the equation.

I added up the costs once to nuclear power and it seems so very uneconomical to me when you take into account everything, I'd just rather see money going elsewhere. Decentralized Power to the People.

[zetreque]

Now I don't know the exact details of storing waste at yucca mountain, but my main reason against it is that once they store the waste it's just an incentive to continue creating nuclear waste and build more nuclear plants when i'm against progressing with nuclear. I would much rather see the billions of $ put into newer better and more simple technologies, using the sun and wind, such as thermal towers rather then spending millions fighting nuclear waste court battles, and public concern ect
