  • The dumbest answer is always right, its a ball of DNA.

  • If the things your trying to explain are smaller that the wavelength of light I suppose things are going to be a bit hard to explain in terms of things we can see/think about, comprehending it visually would be like explaining how a ball bounces to someone who has been blind all there life.

  • I'd say it's a wave nature with resonant mechanisms that can interlock waves to be standing and thereby have particle like properties. the wave aspect is the only one that never goes away.

  • Sounds more like the "wave" idea refers to the probability of finding a particle in a given space. I'd imagine particles that have more energy have a larger wave spectrum that they can be found in.

  • geez nobody here understands wave theory? its the basis of quantum mechanics

  • Today may chem prof called him de BROGGLY, and I died a little inside

  • Mindfuck of the week: Complete.

  • this guy is confusing matter waves with quantum fields

  • I remember somewhere that I read that the material a wave of water is moving through does not move in the horizontal motion .. Like a wave of water .. the ups and downs are not actually traveling in a forward velocity but the momentum of the wave still travels at a finite velocity forward. So like this wave of water, might the wave of an electron be emitted and its energy transferred while its particle traverses the vacuum separately and hence the electron being wavelike and particle like.

  • you think maybe thats why electrons have energy levels.. because the wave has to be a standing wave to surround the nucleus in order to exist at all. just count the peaks

  • - What is it?

    - Its screwy.

  • As anyone tried proton microscopes for the increased image quality? I see problems but I was wondering about it. They are probably harder to "eject" into an object and they may be too destructive.

    What about neutrons? I don't know how you'd observe the neutrons but oh well.

  • @raydredX After a quick google search a prototype neutron microscope was made 6 years ago, but it only had a 0.5mm resolution and a 10x magnification.

  • @bradkey98765 Interesting. Thanks. I'm not sure what 0.5mm resolution AND 10x magnification means. I suppose it doesn't imply that it has 0.05mm resolution otherwise you'd say that.

  • @raydredX Well, it produces an image 10 times larger than the specimine, but two points within 0.5mm get blurred together.

  • @sixtysymbols Why do electrons have mass but photons don't?

  • @mzyzer19 Because they fall into two different classifications. An electron would be a fermion, whereas a photon is a boson.

    It's kind of like asking why people eat food and my water bottle doesn't. The easiest and most elementary answer would be to say is because they are two completely different things.

    Just to clear things up.

    A boson can occupy the same place in space.

    A fermion cannot (Which is why we don't fall through the ground - We are made of fermions)

  • @Duodecillian thanks 

  • @Duodecillian re: falling through the ground, isn't that actually because of electromagnetic repulsion between electrons? I was under the impression the fermion exclusion principle only applies to the structure of the atom itself except in very high density situations, such as that thought to exist in the centre of neutron stars. I'm not a physicist though!

  • Is it screwy?

  • "so if u dont like it blame de broglie" HAHAHAHAHA

    altough, if we rased every kid with the basis that light can act as a particle and a particla can act as a wave, we'd never have this confusion, reason being, just as we accept that a light ray is a wave, wed also accept that matter can be a wave as well. its all to do with what we find acceptable or not :)

  • Comment removed

  • WAVICLES :D

    

  • Moral of the story "he cant answer it in English bc its screwy!"

  • Comment removed

  • i belive the elctron wave theroy part is true otherwise how could you explain how electrons escape and mix with other elements?

    

  • @SilvonesProductions Using a particle model which would fail but it would be able to explain that if you forget the minor minor detail that no atom would last more than a tiny tiny fraction of a second?

  • this is so boring yet interesting!

  • I was starting to get the impression that he thinks it's screwy.

  • Waves and particles are both human interpretations of the things we see around us, normally at a macroscopic scale. At the most fundamental level light is simply light, and we apply the ideas of a wave or a particle to it to see if it fits mathematically. Although it is difficult to conceptualize the world of quantum physics behaves differently then the macroscopic level we are most familiar with

  • Louis De Broglie great idea that everything has wave-particle properties is one of the principles that Quantum Atom Theory is based upon. In this theory we are all made of particles but over a period of time we are waves in a process of continuous creation or change. A process that we can interact with turning the possible into the actual therefore Heisenberg’s Uncertainty Principle is the same uncertainty we have with any future event.

  • Summary: It's screwy

  • I begged our physics teacher for a better explanation when they told us about the particle/wave thing at school :)

  • @phelepone, look up the double slit experiment

  • so what if they do both? an electron particle travels in a wavelike motion? it would still be a particle but it would be traveling real time in a wave pattern around a nucleus. Is this not possible?

  • Is the term screwey a scientific term, or is that just the word he uses...?

  • he spent more time explaining how it shouldn't make sense over telling us the idea itself

  • @TraXXXtar Because thats how it is apparently.. he says it still screws with his head so you can understand his problem. I thought it was explained better than ive usually heard it explained.. its usually very annoying because it makes very little sense. Good to see someone tell it as it is.

  • Brady, so you want to know what it really is? Then check these vids out:

    "07 What is Light?" (v=J-NB5vg7woM),

    "23 The Slit Experiment"

    (by user bgaede)

  • People get confused about wave/particle duality. Is it a wave, is it a particle?

    A better way to look at it is this: what do you actually mean by a "particle" at that scale? We think of it as being something tangible, like a little ball but little balls are made of things. Confusion is arising from our preconceptions of what matter is on the macro scale.

    The answer is to realise that our intuition for subatomic particles is misguided and we should think of them in the ways experiments dictate.

  • I use to fantisize about every peice of matter are in fact waves, and that's why we're affected by sounds like music, as we would then be made out of the same =P

    Pretty naive, but this kinda fuels that idea, heh.

  • aren't the waves, waves of probability? meaning, the particle is more likely to be somewhere where the wave is more pronounced!?!? (Hence the wave-particle duality). Or am I thinking of something completely different?

  • @pilotwave

    That is Schrodinger's idea: that the wave is wave of probability. The "particle" is measured at the location where the probability function "collapses" - when you stop measuring, the waving continues.

    Seems easier to think in terms of fields - there is an electron field. It has a probability function associated with it, and when you poke at it, it converges on the poking and appears point-like . . .

  • The professor's explanation is so screwy that it is refreshing. This is a video that makes a viewer daydream about their universe... Definitely one of the best sixty videos!

  • Thank you to the power of Sixty

  • "It's screwy, it's completely completely screwy.." lol

    What an amazing theory..... electrons replaced by waves? This is the first time I heard about it..

  • Could deBroglie's theory be considered a sort of proto-string-theory?

  • bill gaede's Einstein's idiots video's tell a different story about particles and waves, i wonder if you've any thoughts on Bill Gaede

  • as level Physics... Got my exam on Monday

  • @itrader247 me too

  • as level Physics... Got my exam on Monday

  • Just shut up and do the math!

  • clearly has no understanding of the "nodes" we cs refer to... which btw is a far simplier idea.

  • I really do like the quantum physics videos but would you be able to branch out and talk about computer physics?

    I've always been interested by how a computer program script is translated onto a circuit board.

  • Okay, the wave/particle duality is actually pretty easy to explain. The Hiesenberg Uncertainty Principle states that by observing a particle (and therefore shining light, which DOES have momentum) you are changing the position of that particle. As such, you can never really know exactly WHERE a particle is at the same time that you know it's velocity. The wave is really just an approximation of where the particle will be at any given time.

  • @Stea1thPrawn that doesn't explain the double slit effect

  • I also feel we should blame de Broglie

  • this is very screwy...

  • "If you don't like it, blame de Broglie, because it's screwy, it's completely completely screwy."

    [This is amazing. Thanks!]

  • More quantum physics!

  • It would be interesting if they dropped something in about Bohm's Pilot Wave interpretation of QM. While I don't necessarily agree with it, it is based on an interesting premise, that being that the de Broglie wave is basically a path which determines the path the particle in question follows. It's certainly an interesting debate to have.

  • I already knew de Broglie's work and I find it wonderful, strange yet wonderful. I am ashamed of some physicists who have put this argument aside without even trying to analyze its fundamental idea.

  • @ispravljat

    Um......what?

  • nice ending . :D

  • Comment removed

  • @radbot1 In fact the more I learn about science, the more my faith in God is reinforced. Science is just so amazing the way it tells us how amazing the universe we live in truly is. Knowing how the galaxies formed under gravity, knowing how we evolved from single celled organisms, just makes it more brilliant and wonderous. I really can't see how the bible can be proof of anything when it's a man, not god made book full of non-sense, and I really can't see how science has disproved God either.

  • Ok, Let this be the last word on God cos these irrelevent baseless aurguments really bug me.

    First of all, I do believe there is a God and heaven. However many of the religious nuts on here are just that, NUTS. People living for 900 years, it must be true cos it's in the bible, that's just bollocks. They are trying to turn people to God but their non-scence is doing the opposite, the well meaning fools they are. I also believe in science, I love science. The two beliefs are NOT exclusive.

  • @radbot1 The idea of people living to be 900 is no more ridiculous than the idea of an all powerful sky fairy.

  • @bl4ck0p You are right. But who ever said God was a sky fairy you moron haha!

  • What happened to the double slit experiment? Have you done a video on it yet?

  • @itsmanofpopsicle They've actually talked about this in the video about electrons...

    Bye.

  • My understanding is that electrons do not orbit the nucleus, but instead occupy all possible positions. Instead of a satellite orbiting the Earth you have an atmosphere wherein the electron occupies all possible positions around Earth at once. It is only when the electron is measured that is appears (briefly) to occupy one position.

  • 4:42 perpetual motion?

  • @Films4You Which part specifically? The electron 'orbiting' the nucleus? The wave existing around it?

  • what asshole could possibly hit the dislike button on this?

  • @Wittgensteinism because people like you that give them attention and recognition

  • @BibleBurnr You honestly think people hit the dislike button just in the hopes that someone would come along and give them attention and recognition?

    I could invent reasons too. But i'm asking specifically, what kind of asshole does that, not why they do it. I obviously get they do it to be an asshole, but why would an asshole be watching a video of this nature in the first place. I mean, if they're interested this stuff, they can't be THAT big of an asshole.. so what KIND of asshole?

  • @Wittgensteinism they do it so they can hear you bitch and whine about it. you are the cause.

  • awesome shirt.

  • @nequillim hello...?hello?heeelllooo?are u still there? Are u standing on yr roof with a tinfoil helmet and antenna, by any chance...? Ahhh, weeelll.... u will just have to wait for next year, 2012, I guess, if u missed the boat this time around. Maybe god forgot, or something. Maybe the note he wrote on the back of his hand washed off, or his alarm clock was accidently set on pm,instead of am-I know thats easy to do, and sux when it happens.No-one EVER believes ya when ya pull THAT one, lol.

  • u said yesterday "Thanks to science and all you atheists, the world has to end on May 21st. THE APOCALYPSE IS YOU'RE FAULT. We'll see who's laughing when I'm in heaven and your in hell."

    So hows it all going today, nequillim? Are u in heaven yet? Im in the southern hemisphere, and almost 16 hours into the last day in the world. When should I expect it to end? It's pretty hot here in hell, but we always DO have the aircon up a bit high at work for all the elderly patients.have u been raptured?

  • @nequillim well, only a few hours o a day to go now, nequillim user and abuser, and we can both have a laugh!

    dont stress though - the world ends next year 2012 too, for all those who for some reason miss it this time around, of whom one I may be, as its going to be a very busy day for me tomorrow and I may just end up forgetting all about it, heaven forbid! do u thing I should set my alarm, or write a note to myself, maybe...? would be terrible if god forgot - I hope he has his alarm set too!

  • @nequillim no moron.......science has saved more lives with clean water.......

    than an eternity of prayer........

    all you seem to contribute to the human race is a digression of human morals....

    and a mass amount of fear that alot of retarded people like yourself grab a hold of.

    its a self regulating mental disorder.......

  • I thought it was just me! Thank goodness no one else can picture it either.

  • some people really just want to distinguish themselves rather than garner "admiration" and all that stuff.

    and when i was young i generally told "ok, bright in SOME areas, but terrible at alot"

  • i was gonna say the same thing about poliakoff, and add things like, "yesss... i've always quite been different since i was young i would always be told how clever i was... of course it was obvious by my hair and how i've guided students and inspired them... blah, blah" and other stuff....

    but i might give the old man a heart attack. seriously.

  • ?you're right! it's a stupid, STUPID idea! why on earth would you want to do this like this and use nodes and... this is just screwy! why just not use number that's what computers are good for. he's just an unnecessary "theories" because he has too many time in his hands."

    i'm an old british scientist who's a critic of the work of everyone else because it makes me "smarter" than them. even though i've only published a few papers and none of which are great significance TO MY FIELD.

  • the description of deBroglie's assertation of needing to make the wave function "real" reminds me of Kepler's being bummed out at the fact that elipses worked better than perfect circles.

  • @MoonBurgle or the way Godel went insane from his mathematical studies

  • so its basicly de broglie wave is the fluctuation along surface of a radial volume !?

  • @nequillim

    Good job mate.. Did you know that wars over religious beliefs have killed hundreds of millions of people? Did you ever think that you don't actually know what you're saying?

    Go read before you speak.

  • Thanks for not explaining anything....

  • @UKDiscoDave He explained plenty. It is for us mere mortals to strive to understand. ;)

  • It's stupid

    It's screwy

    I love this guy.

  • Intuitively your mind is wired to think in discrete objects, particles. But that doesn't mean particles exist, so I don't think it's actually that silly.

    I'm more an auditive person and don't have strong visualization skills. Maybe it makes more sense to one person than the other depending on how they experience the world.

  • Wow!

    I almost didn't watch this since I had a lot of subscription videos and I didn't know what this is about, but this is the best video I have seen this year!

    That makes perfect sense to me (which probably [almost certainly] means I don't understand a lot of what it's based on ^-^ ) but no matter. What a fantastic concept, almost obvious really when you think about it.

  • @crabid thank you... Glad you chose to watch it!!!

  • he makes it out as if its unexplainable but really it is with knowledge of a few equations... young slits experiment

  • "...Not well known except for some physicist's". We learned his theories in grade 12 physcis and chem class. not to mention every year of university :P!

  • It being screwy and having no mental image to relate to is why this stuff never made any sense to me.

  • @nequillim thats the most retarded statement i have ever heard.......

    explain yourself.......

  • @azmanabdula haven't you heard?

    The bir... ooops, world is going to end *muffled snigger*

    I wonder indeed who will be laughing, my bets are on the people who don't think the world is going to end... :)

  • @nequillim please stop using those drugs. Are really hurting you.

  • I have no idea what just happened. I can normally just about follow them. Haha

  • The future seems a bit uncertain ;)

  • Quantum physics...so odd XD

  • I'm about to take my A level Physics. This helpeda lot! :)

  • @nequillim Let's go back into the history books, around 3000 years ago, there was civilization within Egypt known as egyptians whom would've never been exposed to something like science. There are clearly not resources withing the Egyptian desert to conduct experiments, let alone survive and thrive. The life span of an egpytian was even shorter than what is currently today and it would be impossible for them to be exposed to the "billions of toxins and poisons".

  • @niquillim You can't use religion to hide behind facts.

  • @nequilim You can't use religion to hide behind facts.

  • I love how this has turned into a religious war. I came here to help me for my upcoming physics exam.

  • 1.47 I thought you knew how to say it?

  • i imagine elektrons as a wave...as just particles that wiggle. like you put a point on a sinus for example and let it wander across the function...th way it takes...it wiggles like a wave but is acutally just a point. thats the imagination i get from those theories...

  • There's also to say that wave-particle duality proved true also for fullerene C60: someone actually managed to diffract a beam of fullerenes.

  • I think light is just a particle. If you were to observe a boat going along some calm water, its just a boat (boat being the particle). If the boat is going along some choppy water, does the boat become a wave and a boat? No. Its still just a boat. The particle is just being affected by the water of the universe (gravity, dark mater, magnetic fields, etc.)

  • @mistermoo564

    ORLY?

  • Comment removed

  • hi guys does any of you know How can I upload videos the same quality as this one?

    What format is this video etc.?

  • If you take requests from fans, how about more on Paul Dirac 's work on QED & Hamiltonian theory of constraints next? I'd like to know more about the problems with the translations into mental pictures...Simple enough for a non-expert to make out.

    Don't ask for much, do I?

  • this fucking accent. i can only understand normal school english but this accent is so difficult to understand :(

  • @lilProPUA Since I went to an English school, in England, and I speak the normal school English of my classmates, I think it is you that has a problem understanding English as it is spoken by native English speakers.

  • 0:00 - professor at the dentist

  • Cool!

  • Do you actually know how or why ANYTHING works, or is it all about replicating simple experiments and memorizing an irrelevant story or two about the lives of people who make the discoveries?

  • @Skindoggiedog

    Wow, the trolls are out in full force tonight!

  • @Zolotniik aren't they always?

  • @eseurg True, but it wasn't trolling. I learnt nothing from the video. This prof never explains how anything works. The others do.

  • @Skindoggiedog I agree with that, actually found myself feeling more ignorant than before when I finished watching the video. But I still love the guy, he's so english it's funny.

  • @eseurg Because I'm English I am funny? Well it's true: when I taught a semester at Brown University the students thought I was funny because my accent was strange. Just like Benny Hill.

  • @MrOldprof Well, to be fair: This probably is one of the hardest things to explain to an ignoramus like me in 7 minutes. And - on the topic of being funny - yes, I think a certain degree of "Englishness" is funny, in a very likeable way. Not ridiculous, more like Monty Python funny.

  • @Zolotniik There's no need to be racist about it.

  • i had an AP exam on this here in the US just last week haha was pretty easy

  • Really enjoyed this... Sixty Symbols, to me just gets better and better.

  • @MrOldprof That was REALLY good! I must say, I reckon you've got this totally mastered now. relaxed, casual, and making speaking at Brady's camera business look easy.

  • @nequillim science is awesome! Science discovers neat, useful things such as contraception and birth control. and I'd best shut up about now.

  • uhh, i reallly hated this lesson in high school xD

  • AFRO!

    

  • If only this video would've been uploaded a week earlier, I could've had the two marks I lost on my A level exam.

  • Sixty symbols could you possibly change your comments to pend approval? In every video of yours there is a stupid argument about God. Don't get me wrong its great that this topic is being debated, but after the umpteenth time seeing it is just a bit old :-P Loved the video by the way :-) I have an exam on this soon :-)

  • @nequillim The Fall of Man is not science but God's infinite wisdom. His infinite wisdom to threaten the only two people (which he later couldn't find for a moment) with an, up till then, completely unknown concept. For at the time there wasn't any evil or death, so the two didn't really know what he was talking about. And of course his infinite wisdom to create an evil talking snake that would convince people to do evil.

    God just doesn't want to deal with the consequences.

  • @nequillim He's also responsible for all the electronics in your home - including your computer. Smash it and go back to carrier pigeons.

  • @nequillim No it's not.

    If it wasn't for torture there would still be 2 million people alive.

    If it wasn't for science there wouldn't be 10.3million people alive.

  • @nequillim You're a fucking moron. The typical lifespan back then was 25-40 years. Noone EVER lived to 900 years. This story has been repeated throughout history and religion - while the people who spread it only lived 40 years...

  • @nequillim If it wasn't for science there wouldn't be 10.3million people alive to kill in the first place.

  • @nequillim Your comment is the single most unintelligent, absurd thing I have read this year. Congratulations.

  • @nequillim I'd like to point out that even if one goes by the bible's account of things, letter for letter, number for number, word for word, people weren't living 800-900 years before the fall of man. Adam and Eve hadn't even had a child yet before the fall of man. there weren't 800-900 years between biblical creation and the fall of man. But most of early genesis is more of a parable anyways. People like you who say science is a waste should have everything modern taken away from them.

  • @nequillim HAHAHAHHAHAHAHAHAHAHAHAHAHAHAH­A......*takes breath*.. AHHAHAHAHAHAH. Go home idiot.

  • @nequillim You are so ignorant, before science the average lifespan of a human male had been 40 years but because of the expanding research in medical science, the average life span is now 60-80 years, a drastic difference. If you say science is the blame for decreasing human's life span, explain to me how it is then? because I would love to know. Biologically it is impossible for the human body to maintain functionality for over 100 years, ones who do so struggle to only survive. Please Respond

  • @Riushinn Dude, that guy is trolling. Don't waste your time. At least a REALLY hope he's trolling.

  • @Riushinn Dont feed the troll

  • He didn't give a good expplanation...... Screweeeey...

  • @josyula547 I agree

  • @nequillim ohhh trolls, what a waste of air

  • @nequillim You have an extremely narrow idea for what science is. It is not just weapon creation. Science also saves millions of lives every year with things like vaccines to prevent diseases and safety devices in the vehicles we all use to get around. and now cleaner energy sources so we can eventually stop burning fossil fuels.

  • @nequillim You got that wrong... You are useless and stupid. Science is very good for creating things like the computer you made your retarded comment from.

  • Stop saying screwy!

  • He is talking about light and electrons as if they were two seperate phenomenons. But isn't light make of electrons? It is after all called electromagnetic radiation.

  • @flooodis No.

  • @nilbud I don't believe you.

  • @flooodis A photon has no mass but an electron does.

  • @nilbud this is true but I find it odd that photons have momentum.
