Physics 10 - Lecture 17: Quantum I

[LartenAndel]

Note that a year at Berkeley isn't 100,000 dollars. Its 11,000 for instate tuition. Large difference.

[2eelShmeal]

Now that I am up to lecture 17, I must say that while this course has been very informative, I can't imagine someone spending $100,000 for it. The entire course is a sort of gloss over of the science. He never goes into great detail, and often even suggests that the students "Don't really need to know this" and "Don't really need to understand that". He discourages probing deeper into things.

If I'm spending $100,000 I want some details. Common advanced placement HS students know this stuff.

[MEpianist]

@2eelShmeal Read the god-damn title of the class

[2eelShmeal]

@MEpianist YES FUCKFACE ...FUTURE PRESIDENTS..... I GET IT...

Then tell me this: What the fuck does a future president need with a physics course that costs $100,000 but gives no more details than the History channel does in a typical hour long program? I mean what the fuck good is a physics course that just skims over important details? If all you wanted was an overview of physics (which is all this course provides) then why pay 100,00? It's because people don't earn status, THEY BUY IT.

[MEpianist]

@2eelShmeal No one pays $100,000 for one course. And no physics major could rest on this class alone. This is obviously an overview course which necessarily discourages thorough interrogation of more advanced classes.

Now, I'd generally agree that tuition inflation is a problem but I'd point more towards Big Business that desires indebted workers and Big Government that desires lower unemployment. Now, why don't you just admit that you didn't read the god-damn title, you obnoxious twat.

[2eelShmeal]

@MEpianist You win Mr. youtube bully. As far as being an obnoxious twat, well you are what you eat pal. Maybe someday you'll experience that too.

[MEpianist]

@2eelShmeal Yes, sex jokes, now we've gotten to real issues.

[nickharvey7]

Could quantum mechanics represent the passage or Arrow of Time?

This theory is based on just two postulates,

1.The first is that the quantum wave particle function explained by Schrödinger’s wave equation represents the forward passage of time or Arrow of Time itself photon by photon, quanta by quanta or moment by moment.

2. The second is that Heisenberg’s Uncertainty Principle that is formed by the wave function is the same uncertainty we have with any future event.

[wirsindheldenowns]

this guy is funny! 

[Poleschs]

What camera is used here, for the infrared videos?

[cosmicfeedom]

why wount they hire you if you pass the exams look at e=mc2 that was made by a guy how didnt make it to grade 12 think about it!

[Poleschs]

@cosmicfeedom Albert Einstein had top grades in school, he was the best student in 6 of 8 subjects. He studied physics, mathematics and philosophy.

[MAMONT2REDbook]

somebody please please kill the camera guy!

[witalian1]

Well actually, what we call a "flame" is a stream of hot gas, that's glowing. The only difference is the traditional notion of a flame is glowing in the visible specter while the exhaust gas is glowing in the FIR.

So I guess this is actually a flame, but it's only visible in the FIR.

[leparditas]

iiiiiiittttttts ssssssssso  cool

[Terje1337]

I hear you guys complain about paying for education. I live in Norway Highest GDP per capita, We got one University in the top 100. The university is around 98th best or so. It is fucking ridicilous. 100k might be too much for school, there should probably be a cap, but free schools is bad.

[davese65465]

You morons. This is an overview for non-majors. You're not getting a Berkeley education for $50.

[rabbitwho]

Hang on: What's causing the reflection on the wall? It's reflecting infrared. So walls can reflect invisible light.. i assume it must have been a very smooth wall.. but i know if you move a brightly coloured sheet next to something bright you usually see the bright colour reflected onto it, so I guess there's loads of reflection going on all the time that we can't even see. Maybe even types of light and forces we don't know about and probably always bits of colour but not enough to see

[toughtwavemachine]

yeah I sure am glad education in finland is free

[awsomepeace]

Who knew the professor was an atheist?

[betsiej]

Its quite obvious, he's a physicist

[Terje1337]

@awsomepeace every smart guy is a atheist.

[nickharvey7]

Good video!

In my video The Paradox of Schrodingers Cat an artist view Light has symmetry that forms the geometry of spacetime. Could this explain the paradoxes of quantum physics?

[badnewswade]

This isn't quantum - this just all x-rays and stuff! Wotta swizz! :-(

[nanobot81]

like the history lesson that comes with the lecture. we need more professors like this.

[worsecards]

SOMEONE ALREADY SAID "COOL: FREE INFORMATION TAUGHT VERY, VERY WELL"

please make comments about the material so we can all learn more instead of how incredible the concept of free knowledge is. i think we can all acknowledge the greatness of this concept.

-maybe talk about a cutting laser you know how to make or efficient ways to save money/energy and make cool things. talk about how this is changing the world.

[AllahConsciousness]

Wow! A free college lecture! You know how much money the people sitting in that class paid for this? Alot... This is awesome! Thanks for the post.

[bmikesci]

The reason you need to pay $100,000 for an education that you can get for $50 a month in broadband charges is to get a job. Neither the government nor any other organization will hire you based on merit. You cannot get a degree based on examination results alone. You must buy your way in through the education mafia.

[SabretoothSnowMan]

Just think about the fact that this means that Berkeley University is handing out a free course in quantum physics worth $100,000 and what's more there are no exams to take!

[9hello123]

@SabretoothSnowMan You have to pay $100,000 for this? Wow... This is something you should learn in secondary school...

[judgles103821]

@SabretoothSnowMan no degree either....

[joeglimmix]

@SabretoothSnowMan this is interesting but you will forget everything in 2 weeks. college is where you learn to use your brain by hard work, like homework and tests, not by just listening

[rabbitwho]

@bmikesci Agreed. People should be allowed to pay for exams separately in most subjects. But not in medicine, because learning all the information in 20 years and learning it in 3 years is not the same and if you can't get through med school you won't be able to keep up with all the stuff you have to learn and all the medical journals you have to read as a doctor.

[bmikesci]

@rabbitwho What's better: a really good doctor that one can't afford? or a mediocre doctor that one can afford? Why would I want a system that only produces doctors for the rich? or pay to subsidize a system from which I don't benefit? G.W. Bush has degrees from Yale and Harvard. Does that mean he's well educated? Or does that mean he was able to pay off the education mafia and buy his degrees? 'Rarely is the question asked: Is our children learning?' GWB

[northbeachfilms]

@bmikesci

indeed, it is a bit of a scam. however, you can pass the STATE BAR in california without going through law school. thanks to an old law which allows people in a few of the U.S. states to go through what is called a "Reader" program. law degrees seem like one of the biggest scams there is.

[Icispanit]

@bmikesci If your watching this to try and get a degree, you shouldn't waste your time.

[DanC9189]

Thats a bit harsh, as far as i can tell the course is to give people enough understanding to know when people in, for example, the media are talking crap. If this was part of a full physics course then i'd agree but i dont think it is.

[andres550]

this is physics for presidents, not physics for physicians!!!

[quarkphotonect]

Its good to know this stuff after this I would not get a PET scan

Thanks Richard Muller!

[mcawhite]

physicians practice medicine, physicists study the laws of physics

[jack19790]

And my kid chews on my pool pass. And my grandma washes darks with whites. And Sara Palin is an idiot.

[grofuss]

So why pay for this course?

[cpricejones]

why pay for any education? i would say aside from the face-to-face help from the teacher or mentor, you need the piece of paper saying you took it.

[welhungjohnson]

Why drop 100 grand for the same education you can get for a $1.50 in late fees at your local library?

[jack19790]

Somebody just watched "Good Will Hunting" didn't they?

[FLAMEUGT]

The Library can not answer all of your questions concretely.

[Focusb4ufire]

the car at the start is an old mk2 golf GTI 16v engine :P

im so sad :P i love these lectures, very informative even although i am a qualified scientist, i still love to listen

[diomedes39]

what do you do if you don't mind me asking

[landin048]

Sweetplague, you are not listening to what the instructor is saying. You can't argue with someone if you aren't willing to listen to them first. Oh, and just a thought....crack open an English book.

[jonmena7]

you fucking emo imbesile WTF do you think is heat. Explain what is your understanding of heat.

[Adkit2]

lol. you talk big but you're so ignorant and wrong. how musing. x.x

the heat from the feet IS light. it's infrared light. which is "invisible light". how dumb do you have to be to watch a lecture on something and then claim he is wrong after he EXPLAINED how it works?

[SweetPlague]

you want to ask me more about physics?

Heat is molecyles reacting, that doesnt have to do with light.

[SweetPlague]

*Updated*

*Molecules.

or in words so your dumb brain can follow:

vibrational movement(kinetic energy) in a substance is heat..

and light has nothing to do with it

[jonmena7]

im sory you dumb ignorant fuck im what do you think vibrational movement of the electrons create, but you know im really sorry because actually you know better than him, and yet here you are hearing him talk. Guess what you are dumber than you think you are.

[mrkvamaster]

to SweetPlague:

What you're talking about is "temperature". Temperature and heat are two different things. Temperature is a measure of the average kinetic energy of particles of a body, while HEAT indeed IS infra-red (and thus invisible) em radiation (=light).

[anomnomnom1]

Well you're unwilling to learn and an idiot,, but I'm going to try anyway.

Red light, green light, blue light, and ultraviolet light are all the same thing. The only difference is the wavelength.

Infared has a longer wavelength, therefore lower energy than visible light. Radio is a really long wavelength, xray and gamma rays are really short, they're all fundamentally the same thing. Still with me? No? Too fucking bad moron, I'm going to keep going.

[anomnomnom1]

Continued (this is my reply to sweetplague):

Every object emits what's called blackbody radiation, based on its temperature. The sun is really hot so it's yellow-white. A coal is a lot less hot so it's red. The cooler, the shorter the wavelength. At the temperature of your thick head, the radiation is in the infared. In fact it's probably glowing a little brighter now since you're pissed off. So yeah, hot things give off infared, which is a kind of light and not molecules moving, you moron.

[triadptale]

"The cooler, the shorter the wavelength." ==> The cooler, the longer the wavelenght.

[9hello123]

@triadptale nope, infra red is a long wavelength.

[idleflaborgy]

you pretty smart but maybe not then agin we'll see if can answer can you? because the thing what i'm confused over is lightening. like is lightening fire? what is lightening? is there, is it cause it's close to space that it's alljaggly? and there's no air in space? can it burn stuff? like could lignhtnig burn fire? does anyone know if theres such a thing as lightenig at the total bottom of the ocean? they(the fish) prolly don't call it lighgtenng cuz fish don't talk lol.oh god what is it!!???

[Adkit2]

uuuh...at least you're asking questions. that's what's important. x.x

[yetidetective]

lightning is an electrical discharge, just like when you touch a doorknob and shock yourself only much bigger.

the doorknob shock is caused by your feet moving over the ground, lightning is caused by clouds moving over the ground and past each other.

[FateMaster2]

I think idleflaborgy wants to know what it is not what cause it. I gues he wants to know what you are seeing while looking at one. Since a lightning is a electrical discharge like yetidetective sad allready a lot energy (electrons) is in movement so the air get very hot building a plasma. We learned already (in the lecture) that heat means lots of vibrating electrons and thiese emit light which you can see.

[diomedes39]

lightning is basically a stream of electrons that jumps between clouds and the earth. it is very hot and can in a sense burn things. fire is the emission of heat and other kinds of light so nothing can burn it. its basically an oxymoron. i do not believe that there is any electrical discharge like that on the bottom of the ocean because water is a conductor and electricity simply flows through it. hope that helps. maybe if these assholes weren't busy bickering you would have found out before.

[kallo1234]

this is good for highschool like me

[IC1101]

Sam Fisher.

[dplandscaping]

I would like to meet professor richard muller and shake his hand, wow!! I wish I had professors like that at my college.

[Tizmahn]

I think it's normal for anyone wether they'd be 14, 27 or 86. We want to understand the world, so we can harvest the energy.

[renigade234]

I have a good question ! Is it normal that a 14 jear old kid is very intrested in this and yes I do mean this because i have watched all the videos and I want to learn more . I told this ma mom and she said " Why are you so intrested in this crap " because my dad and mom are very carp in physic

[CyrusGuitar]

Of course it is normal, any intelligent person is generally inquisitive. I would ask your teachers, most parents are rather ignorant.

[theQbelek]

normal... its not more advanced than a science book for kids in primary school.

[SPRMSSVBLCKFOTSEN]

ive shared this scenario myself and took the advice of my parents wrong move, now at 24 cant help but want to learn more, if you want to be a renegade then its a very good idea to be versed in the truth, and thats all it is, the true picture to the best of our collective knowledge

[TheBlueFalconX]

If it interests you, study it. Get to know it. Like me!

[drexlfoley]

Ive seen a very young child giving a review of richard mullers book on youtube somewhere.

[razielze]

the jump of energy of the electron is easier to understand if we think about fireworks: different elements when burned cause the electrons to jump to higher orbits releasing energy in the form of light, colored light.that's why the gas flame is blue etc..

[FrozenThree]

girl eyes

[therealdrbyte]

this is why we wear clothes future presidents

[diogo0050]

This is not a course for physics majors, these are all history / psychology students. That's why there's no math.

[FermiAnyon]

It is precisely his ability to be casual and interesting with relevant, real world examples that opens people up to what you're saying. I think the beginning part of this was Physics For Future Presidents or something. So these kids are not necessarily coming to the table frothing with a desire to learn this stuff. He can save the complicated stuff for the upper level courses. Keeping it interesting and entertaining is an effective way to open pupils to what you have to say.

[kiriaka1972]

OffTopic:

But, how do you get a 70 minute vid posted to youtube??

I've also seen 30 minute vids as well...how?

[ClerosNZ]

youtube probably got paid

[mathfeel]

you need to pay for an director's account (or similar name)

[agg323181]

He does not include rigorous mathematical analysis coz the course is not for phy majors.. its called "physics for future presidents"...so it seems dat the course is designed to just give an overview of the topics for non-physics students.

[goalieca]

i was wondering why it was soooooo thick.

[HenryDavidT]

This is about science in every day life. The professor tries to explain the various mundane things we take for granted. Anyone who watches and then complains about it, about the professor, or about UC Berkeley should just go down to Tijuana & get drunk. The UC system produces more scientists than any other system of schools, public or private, in the whole world. Just because one is not bright enough to appreciate "mundane" things does not mean others are stupid (or that a school is bad)...

[Andrew2030]

you're absolutely right buddy

[adolfhitlerFABULOUS]

i am sure he is worried that you arent attending berkley when he makes about 150 thousand dollars a year

[Hippyy123]

this is not a class for physics majors , some of them might not know much about physics , he take the time to make it very clear.

[adolfhitlerFABULOUS]

shutup you stupid bitch. he is a great professor. you probably suck your teacher dick to get through school you dumb whore

[hastinbe]

It's an honor allowing everyone to learn, educate, and build an emphasis in physics from someone such as Richard Muller.

The disrespectful and immature comments are clearly marked below and should be simply ignored or nullified.

[nkarinlohit]

This video is great!

[zetreque]

Too bad u can't rate people, that JoanneChristie person would probably have to get a whole new account, lol. Might make a good suggestion to youtube so our time isn't wasted on those retards that waste our time because you can very obviously tell when someone is just being retarded in all the thumbs down marks.

[xperimentos]

Thank you UCB for posting these great videos, please ignore these people that comprise the minority and that complain about anything and everything regardless of what they are encountering.

[kpresco]

Anyone who needs to stress their intelligence with capital letters and swearing obviously is not smarter than the Doctor giving these lectures. You have no provocative insulting the value of these lectures, for they serve their intended purpose. The lectures are free thus you can not be so openly critical of their educational value. Beggars can not be choosers.

[dwarfer777]

poor camera directing, you have no business as a director. quit for someone who else to do it

G-

[LongShlong125]

this is downright awesome , viewing lectures for free!

[perspectual]

Thanks Muller for considering the people at home when x-raying the teddy bear! hopefully one day we can really get to see it.

[perspectual]

I can agree with you to some extent on your comment, if a person 'HAD' to do something they would probably grow to recent it and develop problems unless they knew the benefits.

Addressing this ADD comment, isn't it possible you could have it already? since you don't believe your able to sit through a quality lecture on a daily bases. Many people can do this as it is a perfectly normal experience when attending college or university.

[perspectual]

I do agree with you, if one find something stimulating one can do it for hours but it must be true that many people are stimulated by different things which is evident from the array of diversity present in our society.

I happen to be one that is stimulated by lectures from Berkeley thus I can sit and watch them daily. If you aren't then perhaps it is a waste of time but nice going for giving it a try.

[perspectual]

Unless of course you're highly qualified in this field than I fail to see the relevance to what you believe they should teach and what they are teaching. Physics is the study of energy, form, motion and waves. This seems to be present in these lectures. God, Time travel and the creation of Frankenstein seems to raise more uncertainty than provide useful educational concepts in the field of physics at this point in time which is why its left to religious, philosophical and biological disciplines.

[perspectual]

This 'fact' you believe you stated was encased by opinion. In regard to time wasting its irrelevant, otherwise neither of us would be responding to these comments, obviousely nothing constructional is ever to come of this.

[JoanneChristie]

Now I HOPE that people start to PAY ATTENTION to just HOW MUCH ISNT BEING TAUGHT! AND THATS DELIBERATE!

[JoanneChristie]

Now ACTUALLY I AM HIGHLY QUALIFIED! And THATS NOT THE TRUTH! LOL! Seriously I KNOW SO MUCH MORE THEN THIS GENTLEMAN! And thats the TRUTH! Often its difficult for me to explain CLEARLY! ITS WEIRD! But I PROMISE I AM NOT STUPID!

[perspectual]

If you're neither qualified nor articulate you will generally have a hard time persuading reasonable people of your ideas and concepts. Perhaps this is why I can not understand how you believe these "Introductory to physics lecture for future leaders" fall short of what they are suppose to be.

[kpresco]

Anyone who needs to stress their intelligence with capital letters and swearing obviously is not smarter than the Doctor giving these lectures. You have no provocative insulting the value of these lectures, for they serve their intended purpose. The lectures are free thus you can not be so openly critical of their educational value. Beggars can not be choosers.

[Strider2112]

Hun, its a general physics course in university. It is not mechanics or relativity or engineering, it is a generalization. In fact, he teaches them that the acceleration due to gravity is 10m/s every second, when we all know it is 9.81m/s^2. Clearly, the point is that the idea of the course is to attain a general understanding of ALL physics... look at all the people in the room

[JoanneChristie]

Its at best A FORTH GRADE LEVEL! Actually physics is SO EASY IF THEY WANTED TO TEACH IT! I promise!
