Wave Function (Extra Footage)

[dragos7puri]

We want more than 10 minutes on the subject. The more the better. I could watch these professors explain quantum physics for days...

[anonymousbl00dlust]

*you've got 20 seconds to explain quantum entanglement*

*gives up* hahahaha

[sirkowski]

lol

[SLemonspunk]

Entanglement is the best part!

[rogerdotlee]

So what's this 'partnered'? Does this mean you need to bribe Google to get access?

[YouHadTheMoth]

Prof. Moriarty definitely needs to make a video on entanglement. Please Brady!!!!!

[rogerdotlee]

10 minute limit? There are a couple of videos that I took a look at this morning that were both significantly longer than 10 minutes -- Dr. Randy Pausch's Last Lecture being the first that springs to mind. I'd say that he was grandfathered in, but another I saw was just over an hour, and that was uploaded a couple of days ago.

[Aviatorsmith]

@rogerdotlee You need to be partnered to have unlimited upload times.

[jagara1]

As someone who works in IT I can understand why it is not always easy to explain things in simple terms.

Take the question "will my car running out of fuel tomorrow?" - to answer the question accurately would involve a probability rather than a definite answer.

You may have to unexpectedly travel a great distance, your fuel tank may spring a leak etc...

Science does not need dumbing down - people just need to become smarter!

"If you cannot explain it simply, you don't understand it"-Albert Einstein

":There's a difference between knowing the name of something and knowing something"-Richard Feynman

Mathematicians need to stop using mechanical viewpoints and start studying fluid mechanics and acoustical mechanics

sad world we live in that these people are the so called bright minds :(

[ibook06]

excuse the OT... gretsch white falcon in the background? ^_^ or maybe something similar...

[tydougandrene]

They should give the +10mins to these guys for their contributions to science and knowledge.

[mignik01]

This is ridiculous. He was getting to my favourite bit in quantum mechanics

[mignik01]

sequel please

[unknownfrost]

It seems like Prof. Moriarty would be a great teacher. I would love to take a class...but I think what he talks about is waaayyyy over my head! lol :/

[zurechtweiser]

The bird in the background....

[Xayionify]

quantum physics failed me in this video =(

but i applaud his enthusiasm at explaining

[13someguy13]

I noticed the drinking bird at about the 2:00 mark and was distracted the rest of the video :P

[ericwongty]

so.. is wave function is a function or not ?

i mean.. the f(x) = .. stuff. 

[sbrofeldt]

@ericwongty Sure, the wave function is a function. It is of course different depending on the system you are describing, but instead of the f, we usually use psi, as in ψ(position,time) = ...

[ericwongty]

@sbrofeldt

so.. the equation was the one derived from the poissons' equation about the wave equation connecting the current sheet, e field and b field ?or did i mix sth up..

[SteveUllom]

To me the double slit experiment tells us nothing about the physical world. the particle/wave duality observed i believe is an issue of physiology and perception. Humans have a blind spot but it is a little known fact that everything we every see is in part a construction of the mind. I would bet that the interference pattern is a construction of what the brain thinks it should see. What should be asked is why some predictions are correct even though the theory is hogwash.

[Backo119]

I would so like to enroll at the University of Nottingham!! If I only had a chance..

[ScienceFictionHairdo]

Why stop him at 10 mins:S!?

[markakroll]

Why can’t physicists and scientist alike, just accept, that nucleus bound electrons are simply field dynamics (see Maxwell) that are produced by the nucleus, but which exerts an opposite charge (and act as a physical anti-node to conserve charge whilst satisfying Schrödinger’s Wave Function?)

[jeebersjumpincryst]

Noooooooooo!!!!!!!!!

[AntiProtonBoy]

he was on the verge of revelation and the vid cut out... Aaaa...

[alexanderhulse]

lol i feel so sorry for that guy famous lasts words you "dont know...nah"

[RevDevilin]

NICE ;-)

[nickharvey7]

Could the wave 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? And Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the wave function be the same uncertainty that we have with any future event.

[JimmyFatz]

I recall a description of quantum mechanics (perhaps from feyman, maybe someone else) that compared particle/wave duality to the concept of shape and perspective. A cone from a top view appears to be a circle, but from the side it is a triangle.

[JimmyFatz]

...So matter can be considered analogous to a cone, exhibiting particle (circular) behavior in some respects and wave-like (triangular) behavior in other respects. So asking the questions "Is it a circle?" or "Is it a triangle?" is more or less trivial (its both!). What's really interesting is trying to find the perspective that unifies both views: trying to see the cone, as opposed one shape or the other.

[JimmyFatz]

... there is no cone... :)

[yargh92]

Coitus interruptus of the mind... WHAT A TEASE! Great video, but damn, I WANT MORE.

[SabretoothSnowMan]

I think that even if he ran out of time, I would have lied to hve seen the rest.

You could make it looklike it was going to end, and then say that you were muking around, and then start the rest off.

PS - Yes I know about quantum entanglement, and it gives me a headache but in a kind of fun and disturbing sort of way.

[homousios]

so the wave function collapsed? Is that why it ended so suddenly but I think it is the 10 minute limit

[opiumgland]

No. No sequels. Truncating the video as it fails to reach a neat coherence embodies the concept quite well.

[nottinghamscience]

@opiumgland I agree! And as I made it, my decision is final! :)

[MrVHI123]

MAN!!!! The last part was the climax!!!! Can you please make a sequel for this??? Pretty please?? :D

[smbhax]

Nice try! :D

[jacksawild]

It would be good if you could subtitle your questions. I can often infer them, but not always.

[jeebersjumpincryst]

Grrrrrr!!! Please post the rest of it (so we can all finish not understanding it - never realised how interesting not understanding something could be) but thanks for the 10 mins all the same...

[3rdeye7thdimension]

Professor Moriarty is a wonderful lecturer, especially to try and compress such complex ideas into ten minutes. He's very engaging and passionate about his work it seems. Very admirable. From my understanding, the observation of the experiment (not to be confused with the results) acts upon the subject. I can understand using precision instruments, as they must act upon the subject to measure it, and thus affects it's original course, but does ACTUAL observation affect such things as well?

[chrisofnottingham]

I think the problem with lay scientists trying to understand QM is they don't realise that even the proper scientists don't really understand it. Scientists learn the maths and apply the rules and even build up sufficient familiarity with it all to be able intuit what will happen in certain situations. But what they chiefly do is get used to not understanding it.

[anjundoobies89]

"using an imaginary number, something that cannot exist in the real world, to describe reality"

[aludakris]

I would really like to see the double slit experiment performed, not just explained. Detectors on and off, counters on and off...the whole shooting match. Entanglement is nuts, heck, string theory is nuts too

[clarkcolt45]

this is probably the greatest question of the history of humanity... the one who explains it will become bigger then Einstein :D

[xja85mac]

You should put up a video just about entanglement, it's such a weird concept, and it seem to violate relativity.

[eltotoX]

I really wish you could keep elaborating! I hope to understand more about the strange wave function.

[azamm500]

hi could u explain alittle about cusars and the source of its power

[kebabsallad]

Very interesting and cool, like all the other super abstract theories :D

[Cyrathil]

I definitely look forward to Professor Moriarty's video on the entanglement.

[Qtyled]

I laughed at the ending!

[neen222]

Professor Moriarty make me wish i was doing a physics undergrad degree this year.. perhaps after i've finished my chemistry one :)

I've watched all the mit physics lectures and i definitely second the request by @DanMan7997 i would love to see nottingham lectures in iTunesU or the "YouTube EDU program"

[DanMan7997]

I'd love to watch a good 1hr+ lecture on this subject from Professor Moriarty. Trying to compress the concepts of a subject like quantum mechanics into 10 minutes is just silly.

[nottinghamscience]

@DanMan7997: I'm sure he'd love you to enroll at the University of Nottingham!

And as silly as it is, we won't let YouTube's 10-minute limit stop us from trying! :)

[DanMan7997]

Ha, well your videos certainly are wonderful, just a bit compressed in cases like this one. I subscribe to several educational channels, such as MIT and Stanford, with the capability to post videos over 1 hour. Perhaps you should apply to the "YouTube EDU program"; just google that term.

Regarding enrollment at Nottingham, I'm a bit tied up at my current university in the states at the moment, but Nottingham will surely be on my mind for graduate school! =)

Keep up the great work!!!

[blenderpanzi]

@nottinghamscience You could make a 6 (or more) part series. :)

[me835]

@nottinghamscience make a 6 part video series on it! each ten minutes!

[windowlicker1]

doh!!!

that was intense!! i really want the second part too!

[Osirus1156]

Entanglement is where two particles are linked no matter how far apart they are from eachother. I think...

[CaptainSpaktastic]

10 more minutes please!

Maybe when you have finished the 60 videos with the basic information you could do more in depth stuff like this.

[solomsolomol]

when they say "function" , do they mean the normal everyday use of the word (i.e a certain specific job) or do they mean the mathematical use of the word ? 'cause English isn't my first language and in my language we have two different words for the two meanings (one word for each meaning) , so it would be much appreciated if someone could clear that up .

Thanks .

[Jaratu]

I do believe that it is the mathematical meaning, not the "specific job" meaning.

[Qtyled]

They mean the mathematical function.

[solomsolomol]

well , thanks , that will really help in studying about quantum mechanics .

[ericofcrows]

Encore!

[DancingRoboClown]

I hope you get another video out of this, it seemed like what he was going to explain next was really interesting.

[goldliquid]

lol -_-

[4jonah]

have a part 2!!!!!!!!!

[DeoMachina]

Hahaha, poor guy.

[bb0ss]

nice try

[wilsonlaulau]

i want more!!!!
