Adam this was very well put together! I've been teaching this subject at wellness lectures for a long time and my examples are totally different. This was super fun. Thanks!
such a nice way of explaining schrodinger's cat by rabbits....making your audiens understand quantum entaglement by a simple way.....wonderful! And calling Erwin schrodinger and Hysenberg the real wizards..absolutely true!
I find this quite interesting. look down below all the comments are negative but quantum mechanics states if you find my comment positive then all the comments below will immediately be negative and vise versa. but if you didn't look any comment there is 50/50 you might find positive or negative together and this is quantum state.i might be mad 😂
I don't understand all the negative comments Adam's talk. Please try not to focus on the scientific accuracy of all the complex details behind quantum mechanics in his talk, but recognize that he's trying to spread his enthusiasm about the science to a wider audience with less knowledge about quantum mechanics and inspire them to want to know more about it. The magic in this talk is not about quantum mechanics and whether his information is correct in all details, the magic is in the fact that he's able to intrigue those with less knowledge about the subject. That's a skill to applaud, as not many can do that well.
Why doesn't anyone ever explain *why* superposition is true? Probability is just a mathematical way to describe a system with incomplete information (uncertainty). Everyone knows that I don't pull 2% of an Ace of Spades out of a card deck every time I draw a card. It's a probability of my drawing the Ace of Spades, not a literal description of the card I drew. So why in the case of subatomic particles does this mathematical description of uncertainty suddenly become a literal description of reality?
My best, uneducated, guess: In general, *you* may not have all the information in your mathematical description, but someone else does. *You* don't know which bunny is alive, but the live bunny knows it's alive, and so it also knows which bunny is dead. *You* don't know if the atom split or not, but the atom knows it hasn't split because it is still behaving like a uranium atom. There's always a part of the system that has the information that is missing in your mathematical description. Until you reach the sub-atomic level. At the level of individual particles, nothing is in possession of the missing information. At that level, each particle is its own isolated system, with no information about the particles around it. A single electron has no direct information about its own spin until it strikes another particle, at which point it has the information it needs to understand which way it *was* spinning. So, for all intents and purposes, it is spinning in both directions until it hits something. This explanation leaves me deeply unsatisfied, however. First: it feels like nothing more than a semantic argument. The particle is both *only* because it's meaningless to say that it's one way or the other. And second: even if the universe doesn't know which way the electron is spinning, that doesn't mean God doesn't know which way it's spinning.
humans recognizes patterns when they are not patterns (physics laws such as superposition) .and such a thing as a probability and a chance doesn't exist because it is a human made social construct used to predict future (and there is only one possible possibility of event outcome that is possible to happen due to nature of time flow) . in this case quantum physics is physics of chance???? it's as effective way of proving physical laws as ..... proving zeus(superposition in this case) existence by flipping a coin and saying if it lands it exist(the law of physics).for example there is cat in a box .it doesn't have food for 45 years . will it survive ? people will say that there is 50/50 chance of it dead or alive at the same time . which people call superposition when the cat is clearly in the box dead and has decayed 44.6 years ago. AND.... that makes human's chance/probability system not usable for scientific reasons.and if humans used science instead of chance/probability system it will never be chance/probability again.
That's one way you can think of it. This is called "quantum Bayesianism" and it's based on reading the psi function as representing an observer's knowledge about the system in question. The laws of quantum mechanics then essentially limit the amount of possible knowledge - that is, the amount of information within the physical system itself - that can be learned by the observer to a value below that found in classical mechanics. In particular, the quantum system doesn't contain enough information to give its position and momentum simultaneously, but rather a little bit less (a little bit on the scale of humans and our everyday lives, but a lot on the microscopic scale) and so can only be given up to a probability level. When you go and measure it, you gain more knowledge about one aspect of it and so your wave function "collapses" - or actually is updated to reflect your new state of knowledge, just as the weather man gives you a 25% probability it will storm tomorrow, then when the day passes that becomes either 0% or 100% because the knowledge you had was updated by actual observation. The trick with quantum though is now you don't have knowledge of the other aspect (that is, if you went for position, you have less of momentum, if you went for momentum, less of position - and if you go for both, you hit a hard accuracy limit at sqrt(hbar/2), and this "beveled teeter-totter tradeoff" is because there's, as said, not enough information in the system to determine both properties at once.).
I have one concern about the notion that observing the contrary action of the electron when subject to close human observation at the double slit. The outcome of this experiment indicates that the electron/photon intentionally remains a singular object, apparently at its own volition. What concerns me is that when we view the same experiment at a distance, the electron/photon is somehow unaware that we are still observing its action and happily transforms itself into a wave function. Is this a conundrum worthy of explanation?
Something I've noticed is that he's making a lot of mild jokes , which wouldn't make an audience erupt with laughter, but can be very effective in a book. He could be a writer. Is he already one ?
Okay i felt the never getting that Hogwarts letter in my soul. After i turned 11 just waiting around like any day now.... haha low key still waiting its fine
Funny that Schrodinger's cat was intended to criticize this "magical" interpretation of quantum mechanics, but is now being used to explain it. When magic is involved, it just means that you don't completely understand it yet (the behind the scenes part).
Quantum mechanics doesn't actually say that the rabbit is alive and dead at the same time. Schrödinger came up with this example (the cat in the box) to show how idiotic the idea of superposition is. Superposition is an axiom of the Copenhagen Interpretation of QM, not of QM itself, which is well verified. Einstein was deeply suspicious of this collection of mysteries, particularly the assumption that Nature is probabilistic in nature. David Bohm came up with an interpretation of QM in 1952 that does away with superposition and most of the other "mysteries" of QM. The only ones that survive are those involving nonlocality, such as entanglement. All Bohm asks is that we include, along with the Schrödinger equation, the initial positions of all particles in the experiment, a reasonable requirement. And Bohm's view was supported by the great Irish physicist John Bell and has been verified by two independent experiments.
Not "instantly" but yes it does and did move faster than light - in fact the farthest galaxies are moving away from us faster than light, even right now. (In the early epochs of "inflation" the "horizon" distance to where things were moving away faster than light was simply vastly, vastly closer to the observer) The reason that's okay is that's not actually a movement THROUGH space faster than light, rather it's that the space is undergoing a "scale-up" transformation in some sense, like when you blow up a bitmap on your paint program. The blowing-up does not make any pixels move relative to each other, rather they just get larger and further apart. It's not quite like this though because the "pixels" here, meaning individual objects, don't expand themselves, but the points representing their locations "move" in the same sense as a zoom-in or scale transformation changes the sizes and positions of pixels on a bitmap.
This is how I play life : In my mind I'm playing these ALWAYS!!! *This is my best example* : I have 10-20 chess boards 1 is called *health* the next might be called *time* the next might be *goal* and so on so on.

The next part of that is that every board is now not chess. It is now changed to all different board games and I might associate people to those board games (for now) but I can finish these games at any time, regardless of whether it is ME or THE REACTION OF *ME* MOVING....

A question to all the scienceenthusiasts in here: " - When I think of all these things like Schrödinger´s cat, Heisenberg´s uncertainty-relation and Maxwell´s demon it appears to me that it looks like different expressions of the same phenomenon. And it kinds of hit me that Einstein´s relativity-theory does the same! Am I right?"
I've always wondered why say Quantum physics doesn't work on large objects. Of course it does! It's just specific. You're made up of the little things it can effect.
*affect And it doesn't work on the large accumulation of tiny objects. My arm might be a macro composition of quantum particles, but that doesn't mean my arm can tunnel through a wall.
It was so right that just this year two smart physicists won Noble prize for it and proved Einstein wrong .. imagine proving Einstein himself, the God of physics, wrong .. incredible!
Funny thing is that shroedingers cat only exists to cope with the fact that we don't know it all and some things are not solveable by statistics. So you don't know whether its a particle or a wave? Well maybe its both at the same time. Our mathematics just can't cope with it. Thus Mr. Shroedinger invented the cat. A Century later were still like WHOA THE CAT while the real mystery lies behind that metaphor, not in it!
I have been using a Transcranial Direct Current device of my own making for about six years. It certainly has boosted my cognitive abilities. I use a basic small volume control to address controlling the intensity. As a side note, I would add that it seems to actually help with manifesting things. In other words, they say that your thoughts have power. In my case, I give more power to my thoughts. Whether it's related to the documented effect that thoughts seem to have at the Quantum level of reality or not, my attainment of things that I want to bring into my life seems to be related to the use of TCDS. Consider that possibility. Prayer, meditation, etc. all brought up to another level with the addition of more power...So, be careful what you wish for.
The rabbit or the cat, in and of themselves, always thinks it is here and alive.... Almost Descartes , I always think I am alive.... Others, experimenting on me, thinks there are simultaneously two outcomes possible....
Haaaaaaaaaaaaaa good. I believe the sons name is Sol. So it’s THAT son. I sure hope you can sleep finally knowing that. Must’ve kept you up nites and it’s not like you can ask him on a email or anything. Fun facts. All 100% true you can research it plz do research everything 1)there is water on the sun. 2) your body is made of stardust over 5 billion years old. Or the remnants of suns that have exploded after burning out going super nova. Same thing. 3-a photon takes over 40,000 years to escape the sun but only 8 minutes to get here 3) the earth is hotter that the surface of the sun. Grass is not green.
The audience looks a bit skeptical to me. And this is good; it shows they are intelligent. Yes, there are apparent mysteries in quantum mechanics, but they don't work the way they are described here. I'll grant you entanglement, but it isn't even described accurately here. The main difference in a tiny scale is that tiny particles like electrons and photons and even atoms can be affected by particles far away from them, merely due to the geometry of the experiment. The geometry itself can affect the paths of particles. And that's it. It does seem mysterious only because we are so much larger than an atom, so our commonsense physics is inaccurate when applied to the realm of the very tiny.
or is the electron already on the other side of the wall. i heard they can be in two places at the same time. two dimensions?
10 лет назад+3
"i heard they can be in two places at the same time" It's not so much that it's in two places at the same time but rather that the system is in a well defined state which does not have a well-defined exact position. If we try to measure the position, we will see that different electrons in the exact same state will yield different results for it's position. The specific measurements for a singular system can not be predicted beforehand, we can only give probabilities. Since we can calculate the probabilities, the average positions which we would measure can be known exactly. It's also worth highlighting that It's not so much about what we can know about the position, it's that there is a fundamental intrinsic uncertainty in position.
mikerevs34 it's nonsense. "quantum physics" is a social programming doctrine. i realize this is a big statement. but if you hear something and go "that seems wrong/counterintuitive"..you're probably right. any position is certain and can be determined through observation.

Jessica Alcorn except that is demonstrably false if you had any awareness of the foundational experiments. Classical predictions just don't work. You can't demand that nature work the way you want it to.
This is really annoying. Schrödinger's cat (and the bunny thing in this video) is just a metaphor. You need to make that clear. Quantum mechanics applies to subatomic particles, not macroscopic objects
Well, that's what Schrödinger thought, and so he invented the thought experiment as a slur on the members of the 'Copenhagen' school of thought who had posited the idea of the superposition of states. Since then, looks like the Copenhagen school were actually right! en.wikipedia.org/wiki/Schr%C3%B6dinger's_cat
the Copenhagen interpretation might be wrong after all because it was the one that scientists at the time "chose" to accept when it reality its our lack of understanding and evidence that makes us blind to the real truth.
Well that's the whole point of a metaphor... and also, quantum mechanics applies to macroscopic objects too, the effects are just negligible at larger scales

This phenomenon is common in televangelism. White people will listen to any crap with an Irish accent. I think they think he's going to start doing Lord of the Dance at any moment.
roger komula it's been experimentally proven using quantum entangled pairs of particles. The information travels instantaneously. If it wasn't so hard to believe, it wouldn't be quite so remarkable
I really wish all these self-help “gurus” would stop using the term quantum mechanics to try to legitimize their practices. They aren’t studying quantum mechanics at a deep and expansive level, they’re just taking a a few bits and pieces of surface level ideas and applying them to their self-help repertoire. Stop. Seriously.
Very poorly explained. 2 rabbits with poison that has a 50% chance of activating? One rabbit being alive doesnt prove the other is dead. He said Its a 50/50 chance of the poison activating... So who says that both rabbits' poison wont activate? Or not activate? Last time i checked, if you flip 2 identical coins, and you check one and see it is tails, that doesnt prove the other is heads. They are independent of each other. They have 2 separate chances of occurring. They arent related at all...
Its nonsense to presume that we have to observe something for it to take on a particular state. If this was true how did the universe form without any observers to trigger anything to move from super position to a fixed state? Its all a bit egocentric and as for the Schrodinger's Cat clap trap let me ask you this. If the Cat is neither dead or alive until we open the box then how can a time bomb explode without observation?
I like your skepticism. The answer to that is, it just is. Tom Campbell's tree in a forest explanation is a convincing one as well. It works so that, as long as data (the bomb) is being collected (the timer) than the data will exist as we know it to be. Or, if a tree falls when we're not there and we come back and check it, it will be down because that's what's expected of physics. It won't fall it will just be as it is. That rabbit display he did is a probability theory that has surfaced recently. Interesting stuff but not convincing enough to me. Although it works very well at a quantum level.
It is definitely counter-intuitive but theoretically true yes. Until we are able to dig deeper into the micro world we can only use math to assume what is actually going only. Most of these ideas are based solely on the math that explains them and not observable tests.
One of the poorest TED talks I have ever seen. Just another person using poor metaphors and magic to try to change dubious theories into fact. When will people physicists realise that just because a theory fits the observed behaviour doesn’t mean they actually understand what is going on.
Those theories are not dubious at all.... Physicists absolutely understand how quantum mechanics work. The problem here is that the explanation is very poor, and confusing. But quantum mechanics are a fact.
Well that's the point of being a physicist. If we figured everything out, there wouldn't be any reason to be a physicist. But just because something's hard to understand and harder to explain, doesn't mean it's wrong. Try explain any other modern field to someone without the background to grasp the concepts fully, you'll reach a similar roadblock. It helps if you can use the maths required and spend some time reading up on the topic, instead of denying it in ignorance
You are compleatly wrong. Physicists only have a set of theories that match the observed behaviour. No-one for example has proved what is actually going on in the single photon youngs slit experiment. The Copenhagen Interpretation has not been proved at all. There are several different theories, this is just the trendy one because it makes it sound magical. De Broglie-Bohm theory or something similar would make a lot more sense.
Daniel No interpretation can be " proved", only disproved. For the same reason pilot wave theory cannot be proved, as it is explicitly non-local. However, QM has built up a remarkable technology using the "nonsensical" ideas of superposition and entanglement. And there is nothing "magical" about it. It is reality. It only seems "magical" to people because it does not match their "classical" experiences.
you are full of s..t, 1st of, light is not the fastest, its is the sound that travel the fastest. 2nd, sun is not 93M miles away, it is about 3K miles away, so please cut the crap
No that's not right and all it takes is a thunderstorm to show it - you see the lightning first, -then- you hear the thunder, even though both signals come from the same place. Or fireworks displays, where you see the flash and the embers first, then you hear the concussion. Again, both come from the firework, but the light hits your eyes before the sound wave hits your ears, so light goes faster than sound. Showing it is the fastest stuff around (well okay, along with gravity waves) is a fair bit more complex, but showing it is faster than sound is literally that easy.
@Cameron B : Though perhaps he believes the Sun is a lot smaller. Then in theory it could not kill you while still being close and hot. Namely, if the angular size is the same so it looks to you the same way it will heat you to the same temperature - how hot you get depends solely on how the heat source looks to your body's view field and its temperature. (This is how a magnifier "cooks" an ant - it makes the Sun "look much bigger" and thus much closer, to the ant, and so the ant gets a heck of a lot hotter, as though it were very near to it. At least, this is another way of looking at the process than just "it concentrates the light" that may be more intuitive in this situation.) But there's a number of problems with that. One can find the distance to the Sun using parallax, and then also, its size; and this is consistent with a much larger and more distant Sun. Indeed this computation was already done in ancient Greece, though exactly how accurate their estimates are is uncertain because of difficulties in translation. However, all of them are much farther than what we'd now call 3000 miles. OTOH I don't blame them for doubting, at least if they've not had a lot of exposure to high education. The usual school system just teaches people to gurge up factoids and much less emphasis on trying to get people to understand why we know what we know. So it's not a surprise some will go for things like flat Earth beliefs, "Sun isn't that big" or geocentrism (which is surprisingly still holds on, and it's because again, "common sense" suggests it's true, even though it isn't, but few people are taught exactly WHY we know the earth is a round sphere, much less anyone to actually try to duplicate the experiments to see for themselves. Al these beliefs seem "common sense" if you don't understand how to actually go beyond them. The horizon is flat (to the limit of your eyesight), the Sun looks like a small object. And they were accepted by almost everyone before there was enough scientific knowledge to show their error.). The ed systems needs to be radicalized - gurging up factoids is not education. Actually learning how to think about things and _why_ things are the way they are and how and _why_ we know stuff is far more important, and with it the factoids will tend to stick much easier, with less boring, numbing rote memorization involved.

And it doesn't work on the large accumulation of tiny objects. My arm might be a macro composition of quantum particles, but that doesn't mean my arm can tunnel through a wall.
@@snes09 - right just like you can't take a hunk of uranium and make a nuclear explosion with it?
@@snes09 it can. Its just that the larger an object is, the less likely the probability
It was so right that just this year two smart physicists won Noble prize for it and proved Einstein wrong .. imagine proving Einstein himself, the God of physics, wrong .. incredible!
Funny thing is that shroedingers cat only exists to cope with the fact that we don't know it all and some things are not solveable by statistics. So you don't know whether its a particle or a wave? Well maybe its both at the same time. Our mathematics just can't cope with it. Thus Mr. Shroedinger invented the cat. A Century later were still like WHOA THE CAT while the real mystery lies behind that metaphor, not in it!
MegaBaellchen Our mathematics is the ONLY damn thing that explains QM.
same thoughts !
Sooooo interesting!!!
I have been using a Transcranial Direct Current device of my own making for about six years. It certainly has boosted my cognitive abilities. I use a basic small volume control to address controlling the intensity. As a side note, I would add that it seems to actually help with manifesting things. In other words, they say that your thoughts have power. In my case, I give more power to my thoughts. Whether it's related to the documented effect that thoughts seem to have at the Quantum level of reality or not, my attainment of things that I want to bring into my life seems to be related to the use of TCDS. Consider that possibility. Prayer, meditation, etc. all brought up to another level with the addition of more power...So, be careful what you wish for.
So we can only be a 0 or a 1 but in quantum mechanics we can be both a 0 and a 1
And with quantum computers we have access to a greater range of numbers that increase exponentially.
The rabbit or the cat, in and of themselves, always thinks it is here and alive....
Almost Descartes , I always think I am alive....
Others, experimenting on me, thinks there are simultaneously two outcomes possible....
Love it!
Yes I was so sad at age 11 when I didn't get my Hogwarts invitation xD
I WAS JUST SITTING HERE THINKING, SO ??? HOW DOES THIS APPLY TO ME,? AND THEN
YOU SAID IT, SO NOW I GET IT!!;🙄🤔😁
Which son is he talking about?
And why does light take 8 minutes to get from him to us?
the universes son, called sol, and it happens to be our (sun), as well, and he was there, visiting sol, that's why it took 8 minutes....
Are u joking... And u sound so serious that no one understands its a joke💚
Haaaaaaaaaaaaaa good. I believe the sons name is Sol. So it’s THAT son. I sure hope you can sleep finally knowing that. Must’ve kept you up nites and it’s not like you can ask him on a email or anything.
Fun facts. All 100% true you can research it plz do research everything
1)there is water on the sun.
2) your body is made of stardust over 5 billion years old. Or the remnants of suns that have exploded after burning out going super nova. Same thing.
3-a photon takes over 40,000 years to escape the sun but only 8 minutes to get here
3) the earth is hotter that the surface of the sun.
Grass is not green.
is it true that speed of light is the fastest speed in the universe?
The audience looks a bit skeptical to me. And this is good; it shows they are intelligent. Yes, there are apparent mysteries in quantum mechanics, but they don't work the way they are described here. I'll grant you entanglement, but it isn't even described accurately here. The main difference in a tiny scale is that tiny particles like electrons and photons and even atoms can be affected by particles far away from them, merely due to the geometry of the experiment. The geometry itself can affect the paths of particles. And that's it. It does seem mysterious only because we are so much larger than an atom, so our commonsense physics is inaccurate when applied to the realm of the very tiny.
or is the electron already on the other side of the wall.
i heard they can be in two places at the same time.
two dimensions?
"i heard they can be in two places at the same time"
It's not so much that it's in two places at the same time but rather that the system is in a well defined state which does not have a well-defined exact position. If we try to measure the position, we will see that different electrons in the exact same state will yield different results for it's position. The specific measurements for a singular system can not be predicted beforehand, we can only give probabilities. Since we can calculate the probabilities, the average positions which we would measure can be known exactly.
It's also worth highlighting that It's not so much about what we can know about the position, it's that there is a fundamental intrinsic uncertainty in position.
thanks,mate.:) i'll always be a beginner on this stuff,but it's fascinating.
mikerevs34 it's nonsense. "quantum physics" is a social programming doctrine. i realize this is a big statement. but if you hear something and go "that seems wrong/counterintuitive"..you're probably right.
any position is certain and can be determined through observation.
Jessica Alcorn except that is demonstrably false if you had any awareness of the foundational experiments. Classical predictions just don't work.
You can't demand that nature work the way you want it to.
You are wrong on so many levels.

This is really annoying. Schrödinger's cat (and the bunny thing in this video) is just a metaphor. You need to make that clear. Quantum mechanics applies to subatomic particles, not macroscopic objects
Well, that's what Schrödinger thought, and so he invented the thought experiment as a slur on the members of the 'Copenhagen' school of thought who had posited the idea of the superposition of states. Since then, looks like the Copenhagen school were actually right! en.wikipedia.org/wiki/Schr%C3%B6dinger's_cat
Nobody's perfect and you learn more from making mistakes.
the Copenhagen interpretation might be wrong after all because it was the one that scientists at the time "chose" to accept when it reality its our lack of understanding and evidence that makes us blind to the real truth.
Well that's the whole point of a metaphor... and also, quantum mechanics applies to macroscopic objects too, the effects are just negligible at larger scales
clarity beats accuracy
Lovely
Now, that was good. Just listened to an American Professor, who said 'aah' a lot, who was not. Ta, Irish chap.
I remote view alot it's def quantum mechanical
I don't really understand anything!🙂
More the time passes in the hat more is the probability of the vial to burst and kill the rabbit due to 2nd law of thermodynamics.

A GUY TOLD ME ONCE HE WAS A TIME TRAVELLER ...I GAVE HIM 20$ THEN HE TOLD ME TO WAIT 10 MINUTES FOR HIM TO COME BACK....BUT HE DIDNT COME BACK....COULD THAT HAVE BEEN TIME TRAVEL? I SAW HIM AND A FRIEND OF HIS DRIVE BY IN AN OLD VAN ABOUT THREE DAYS LATER ..THEY YELLED OUT THE WINDOW AND CALLED ME A DUFUS !!!!!!!!!!
HE DOES NOT DESCRIBE HOW YOU GIVE THE TRANSISTOR A KICK
I think quantum mechanics is incomplete.
this was so entertaining, including his hideous styling xD
Meme magic.
ksztyrix exactly what i thought :)
This phenomenon is common in televangelism. White people will listen to any crap with an Irish accent. I think they think he's going to start doing Lord of the Dance at any moment.
Lot of factual errors. Not sure if the speaker is confused or whether he's trying to oversimplify stuff
Amit Batra it is clearly an oversimplification
Lord Kelvin was wrong about everything!
The automatic no lagtime counter rabbit decider is bullshit.
roger komula it's been experimentally proven using quantum entangled pairs of particles. The information travels instantaneously. If it wasn't so hard to believe, it wouldn't be quite so remarkable
I really wish all these self-help “gurus” would stop using the term quantum mechanics to try to legitimize their practices. They aren’t studying quantum mechanics at a deep and expansive level, they’re just taking a a few bits and pieces of surface level ideas and applying them to their self-help repertoire.
Stop. Seriously.
The lack of understanding of certain events, is do to the lack of the knowledge of the LAWS that bring about the EVENTS.
This guy's explanations are very outdated
I listen to a lot of quantum physics lectures and this is probably the worst one Ive heard in a while
IF HE WAS "AT THE SUN" HE WOULD NOT BE ON FIRE. THE SUN IS NOT HOT.
the temperature at the surface of the sun is ~6000K.. you must have really high standards :D
maybe he was there in winter, so it wouldnt be as hot...
Quantum have not changed nothing only discovered what already exist.
what a talk about nothing
The word "Quantum" in the title should have been your first clue.
The physics of quantum feilds
Very poorly explained. 2 rabbits with poison that has a 50% chance of activating? One rabbit being alive doesnt prove the other is dead. He said Its a 50/50 chance of the poison activating... So who says that both rabbits' poison wont activate? Or not activate? Last time i checked, if you flip 2 identical coins, and you check one and see it is tails, that doesnt prove the other is heads. They are independent of each other. They have 2 separate chances of occurring. They arent related at all...
Its nonsense to presume that we have to observe something for it to take on a particular state. If this was true how did the universe form without any observers to trigger anything to move from super position to a fixed state? Its all a bit egocentric and as for the Schrodinger's Cat clap trap let me ask you this. If the Cat is neither dead or alive until we open the box then how can a time bomb explode without observation?
I like your skepticism. The answer to that is, it just is. Tom Campbell's tree in a forest explanation is a convincing one as well. It works so that, as long as data (the bomb) is being collected (the timer) than the data will exist as we know it to be. Or, if a tree falls when we're not there and we come back and check it, it will be down because that's what's expected of physics. It won't fall it will just be as it is. That rabbit display he did is a probability theory that has surfaced recently. Interesting stuff but not convincing enough to me. Although it works very well at a quantum level.
Observing it isn't the right word, statistically both states are true until measured, that is basically it. It's counter-intuitive, but true.
It is definitely counter-intuitive but theoretically true yes. Until we are able to dig deeper into the micro world we can only use math to assume what is actually going only. Most of these ideas are based solely on the math that explains them and not observable tests.
Lookup the double split experiment. That answers this completely.
That too.
very word gimmickry but not science.
Do this but leave the hats sit for a week. I guarantee look or not youl smell something dead in there
Only talk no proof.
The unfunniest person i've seen in my entire life.
Unlike you which is truly entertaining.
When, exactly, did he tout himself as a comic? Or a magician, for that matter? And I thought I was hypercritical.
...and people actually thumbed up this statement!? It still has 20 ups, how can this go down?
Terrible talk
This guys is irritating.
One of the poorest TED talks I have ever seen. Just another
person using poor metaphors and magic to try to change dubious theories into
fact. When will people physicists realise that just because a theory fits the
observed behaviour doesn’t mean they actually understand what is going on.
Those theories are not dubious at all.... Physicists absolutely understand how quantum mechanics work. The problem here is that the explanation is very poor, and confusing. But quantum mechanics are a fact.
they don't understand how it works they are just talking out their ass using half evidence to speak as if its the truth.
Well that's the point of being a physicist. If we figured everything out, there wouldn't be any reason to be a physicist. But just because something's hard to understand and harder to explain, doesn't mean it's wrong. Try explain any other modern field to someone without the background to grasp the concepts fully, you'll reach a similar roadblock. It helps if you can use the maths required and spend some time reading up on the topic, instead of denying it in ignorance
You are compleatly wrong. Physicists only have a set of theories that match the observed behaviour. No-one for example has proved what is actually going on in the single photon youngs slit experiment. The Copenhagen Interpretation has not been proved at all. There are several different theories, this is just the trendy one because it makes it sound magical. De Broglie-Bohm theory or something similar would make a lot more sense.
Daniel No interpretation can be " proved", only disproved. For the same reason pilot wave theory cannot be proved, as it is explicitly non-local. However, QM has built up a remarkable technology using the "nonsensical" ideas of superposition and entanglement. And there is nothing "magical" about it. It is reality. It only seems "magical" to people because it does not match their "classical" experiences.
you are full of s..t, 1st of, light is not the fastest, its is the sound that travel the fastest. 2nd, sun is not 93M miles away, it is about 3K miles away, so please cut the crap
If we were 3K miles away from the sun, we'd be dead.
No that's not right and all it takes is a thunderstorm to show it - you see the lightning first, -then- you hear the thunder, even though both signals come from the same place. Or fireworks displays, where you see the flash and the embers first, then you hear the concussion. Again, both come from the firework, but the light hits your eyes before the sound wave hits your ears, so light goes faster than sound. Showing it is the fastest stuff around (well okay, along with gravity waves) is a fair bit more complex, but showing it is faster than sound is literally that easy.
@Cameron B : Though perhaps he believes the Sun is a lot smaller. Then in theory it could not kill you while still being close and hot. Namely, if the angular size is the same so it looks to you the same way it will heat you to the same temperature - how hot you get depends solely on how the heat source looks to your body's view field and its temperature. (This is how a magnifier "cooks" an ant - it makes the Sun "look much bigger" and thus much closer, to the ant, and so the ant gets a heck of a lot hotter, as though it were very near to it. At least, this is another way of looking at the process than just "it concentrates the light" that may be more intuitive in this situation.) But there's a number of problems with that. One can find the distance to the Sun using parallax, and then also, its size; and this is consistent with a much larger and more distant Sun. Indeed this computation was already done in ancient Greece, though exactly how accurate their estimates are is uncertain because of difficulties in translation. However, all of them are much farther than what we'd now call 3000 miles.
OTOH I don't blame them for doubting, at least if they've not had a lot of exposure to high education. The usual school system just teaches people to gurge up factoids and much less emphasis on trying to get people to understand why we know what we know. So it's not a surprise some will go for things like flat Earth beliefs, "Sun isn't that big" or geocentrism (which is surprisingly still holds on, and it's because again, "common sense" suggests it's true, even though it isn't, but few people are taught exactly WHY we know the earth is a round sphere, much less anyone to actually try to duplicate the experiments to see for themselves. Al these beliefs seem "common sense" if you don't understand how to actually go beyond them. The horizon is flat (to the limit of your eyesight), the Sun looks like a small object. And they were accepted by almost everyone before there was enough scientific knowledge to show their error.). The ed systems needs to be radicalized - gurging up factoids is not education. Actually learning how to think about things and _why_ things are the way they are and how and _why_ we know stuff is far more important, and with it the factoids will tend to stick much easier, with less boring, numbing rote memorization involved.
@@mike4ty4 There's still very big problem he and other flat earthers haven't solved. If sun is 3000 miles away everyone would need their own sun.
