- Richard Phillips Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the super fluidity of super cooled liquid helium, as well as work in particle physics (he proposed the Parton model). For his contributions to the development of quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga. Feynman developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime and after his death, Feynman became one of the most publicly known scientists in the world.

My favorite part of this clip is how the interview thinks for a moment that Feynman finds the question too pedestrian to answer and yet it turns out to be quite the opposite.
Yes, when he says it's an excellent question. Great moment.
@sgs261 i saw his angle, Feynam was trying to get the interviewer to reveal the entirety of his understanding and expose what actual gaps are missing so that they could fill it in piece by piece together. This is the best way to teach physics since it's rooted in collaboratively turning the abstract and the unseen into something intuitive and innate. Memorize a formula and itll last you a few weeks, but understand the mechanism and it'll last you a lifetime.
he's being a dick, like he always as that. No need to defend assholes
When I go to my physics professor's office to ask one homework question...
+Callutts ...So is it B? Wait... Rubber Bands. So C then?
***** Yep and god forbid your guess is still wrong. That's another 30 minutes of explanation, hahhaha. I know they always mean well though, just want us to learn. :)
If you're just guessing, then I don't know what you expected. Stop guessing and start actually trying to reason about it. _Then_ ask your professor. Your professor doesn't want to waste time with you just trying to get a grade. They're trying to _teach_ you something.
+BladeOfLight16 can you please answer my question
Tbh he explained the concept eventually
i dont know about magnets but i learned allot about ice
Did you learn anything about asking "why" questions? You missed the point if not.
The ice part is actually the one part that later turned out not to be true.
@@rabbitcohen8793 I watched this clip with my stepdad many years ago, and he blatantly stated "that ice thing isn't true!". I like though, that he said "or so they say" after he explains the slippery mechanisms of solid ice as if he had some doubts of those very mechanisms. One of the greatest minds of the 20'th century, for sure.
Yes ... Why not!😂🎻🎉
@@rabbitcohen8793 wat do u mean
Fuck magnets, how does Richard Feynman work?
that is easy, it is so obvious, you can see that
The Feynman Algorithm:
1) Write down the problem.
2) Think real hard.
3) Write down the solution.
The Feynman algorithm was facetiously suggested by Murray Gell-Mann, a colleague of Feynman, in a New York Times interview.
Same thing was said about Albert Einstein by a former student that later on life won the Nobel prize twice! He walked back and forth with his pipe and then gave us the answer. Never learned how history, id worked.
He worked like a better ChatGPT; analyzed the questions in detail and pointed out when questions were unclear. Why reply on a question with 1, 2, 3 or more assumptions about the question itself? Or as we developers use to say: Sh*t in, Sh*t out.
I'm here 8 years later to ask you if you have found why or how he functions as he did. Please don't say you don't know how to explain it in ways I might understand it because you don't know it in ways I understand it.
The best thing I got from this is that the magnets are using a very pure/elemental force. It's not as if magnetic force can be explained by using something else, but rather, other things can be explained as being made up of the magnetic force.
electrical force is more basic than megnetic one. actually they are in some way the same : when a charge moves really fast it creats magnetic field, and it can be presented with special relativity . but WHY when it moves fast it creates that magnetic field but when it's still it creats only electric field ? didnt get there yet in my Physics degree (finished only my first year till now lol)
All magnets have north and south poles. Opposite poles of magnets are attracted to each other, while the same poles repel each other. This is due to the alignment of the electrons' spins in the atoms that make up the magnets. The electrons in the atoms have a property called "spin," which can be thought of as the electrons spinning on an axis, like a planet spinning on its axis. In some materials, like iron, the electrons' spins are lined up in the same direction, resulting in a north pole and a south pole. When opposite poles of magnets are brought close to each other, the electrons' spins in the atoms of the north pole of one magnet are attracted to the electrons' spins in the atoms of the south pole of the other magnet. This creates an attractive force between the magnets, which is what causes them to stick together.
His real point is that science is descriptive. It doesn't answer why, except in relation to something else that is descriptive, within the frame work of a theory. It doesn't even really answer _how._ It answers _what,_ and then creates a "how" that matches the observed "what," which make predictions of other "whats" (called a theory). In other words, things move the way they move because is the way they move. Physics is just about quantifying how objects move/interact and hopefully gaining enough understanding to predict how objects will move/interact in a different situation or in the future (or how they moved/interacted in the past).
"Why are magnets?"
"You want answers?"
"I think im entitled to"
"You want answers?"
"I want the truth about magnets!"
"YOU CANT HANDLE THE TRUTH ABOUT MAGNETS!"
That is because he doesn't possess the Truth about Magnets.
Charles Cagle It's actually because Feynman always believed giving people dumbed down answers was wrong, and to answer the question was to delve into quantum world - and you can't even talk about the quantum using classical metaphors, that wouldn't make sense.
So he provided this long-winded beautiful answer that amounted to "If you want to know, go study physics for a couple of years, ya fool"
@Tomasz Wota ... Oh yes, the famous Feynman! Just on the basis of classical metaphors that you just decried he was just another sheep amongst tens of thousands of sheep that thought that it was appropriate to reverse extrapolate the interactive behavior of two like-charged pith balls or two like-charged balloons (which repel each other) down to the level of discrete quanta. There is not one actual piece of experimental data, for example, that demonstrates that elementary charged particles (like protons and electrons) will interact in accordance to the expectations of Coulomb's Law when they are overlapping in the same momentum space (at or very nearly rest with respect to one another). Not one. Never has been and never will be. In fact, just the opposite is seen in phenomenon such as super-conduction where it can be proven (was proven by Leon Cooper circa 1956) that super-conduction is carried out by tightly bound spin-up/spin-down pairs of electrons. Later in 1972, John Bardeen, Leon Cooper and Robert Schrieffer received the Nobel Prize for having concocted the 'BCS Theory of Super-Conduction'. They got the prize because no one else could explain the Cooper Pairs (of electrons). How could same charged particles be cuddled up together. They couldn't use the same lie that they used with respect to multiple protons in the nucleus because they b.s.ed themselves into a corner using the pseudo-scientific idea of a 'nuclear strong force' only associated with hadrons. Electron, of course, were leptons and so they couldn't explain it by saying 'Strong Force'. As far as their Nobel Prize: Essentially, no one else had shown up. A few years back one of my sons won a wrestling match based upon the same criteria. No one in his weight class showed up at the meet so he won by default. No one understood Superconductivity and no one else had a theory so this false theory, that by the time they received the Nobel Prize, had been disproven many times by the experiments of Bernd Matthais, a scientist at Bell Labs (and UCSD). He was interviewed in Science News in 1970 and said: "Oh, I never pay attention to that theory because its predictions are always wrong." That was two years before they got the Nobel Prize. Philip Anderson the 1977 Nobel Prize winner in physics said of the BCS theory. "That theory has been nothing but a catalogue of failures." When you can break yourself from slurping up the intellectual mast_urbations of people like Feynman and fawning over them like the obvious sycophantic half wit that you are, you might someday come to the realization that Feynman didn't really contribute anything of great value to physics. What he did contribute made it easier to calculate but certainly didn't give any deep understanding to particle physics. When you have the right answer to a calculation that agrees to 9 decimal places to the experimental data, that doesn't mean you understand the physics, but, of course, morons like you would make the opposite assumption. I do take my hat off to Feynman for admitting that he didn't believe that what he won the Nobel Prize for was mathematically legitimate. Now kiss off you half witted son of a b_i_t_c_h ... If you can't do anything more than suck a dead man's c_o_c_k to show what a slavishly intellectually dead person you are in a public forum, you shouldn't post at all.
@@MrSkyboltman99 Wow. You sound like a ranting lunatic from the 1970s who couldn't accept that Feynman diagrams are a useful tool and help to explain fundamental particle interactions. I mean on that basis alone, the thousands of hours he saves students and lecturers alike, he deserved his Nobel. Go pound sand. Hater.

Look up Ken wheeler, he has the answers
RIchard Feyman's wife: "WHY did you not take the trash out yet?!"
*Richard proceeds to go on a long tirade about electromagnetic forces, gravity, string theory etc. until the wife sighs in despair and takes out the garbage herself. Again.*
Brilliant.
Joe Cool ROFLMAO I'll remember that
@115798096783663362194 I admit I laughed. But you didn't watch the video I guess. Because Richard makes it clear that if he can explain why, in terms of something you're familiar with, he can and will. Only if that's not possible do you need a long story on what "why" is looking for and the role of our accepted truths in that.
Joe Cool Sorry to disappoint you but women is a distinct field of science and you have to know something in order to understand something else. You obviously not married, so you cannot understand. So, when your (it applies only to your woman, another mystery too) woman starts a sentence with a "Why", it mean "YOU must...". I believe Feyman would never start an argument he knew he couldn't win.
+Joe Cool String theory wasn't that popular back in his day. I am NOT sure he even believed in string theory
What a wonderful way to respond to a question. :-)
I'd like to applaud the interviewer for just letting Feynman talk.
I feel that many interviewers nowadays are overly keen on pushing through with their initial question when talking to scientists, thereby ruining everything and pissing everybody off.
+MichaelKingsfordGray So did I, but I still watch the web for crime, nature, innovation and Sci-Fi - hope springs eternal...
+MichaelKingsfordGray The same world it ever was, I guess, except that children post emails. Peace. :)
Bernhard Maierhofer thankkss Bernhard....l was dismayed but comments up ther tht ..soo much appreciate appreciation for intelligence
Bernhard Maierhofer You have got to be kidding me! It was such a non-answer!
I’d have walked out. Just because you’re very clever, you don’t need to be a dick.
I feel like I've learned a bit about everything except the question
He answered the real question the interviewer was asking. What is a force? It is what it is! We can model and describe these things but we can't answer the true "why" that the interviewer was looking for. All we can hope to do is see how these phenomena relate to one another, but it will never answer "why". At least that's the view scientists like Feynman have.
Feynman gave the answer in terms of philosophy of science and epistemology, and he seemed annoyed because he regards those fields as irrelevant to what he was doing (he just found it pointless).
mechtech256 "All we can hope to do is see how these phenomena relate to one another, but it will never answer "why". At least that's the view scientists like Feynman have."
The answer to the why could be formulated thusly; because the laws of physics that govern our universe came to be at the big bang. It might not be a singular event, there could very well be a multitude of other universes where the laws of physics are different from ours, the fact that we experience this universe is pure chance coupled with the fact that they allowed us to be. Were the laws any different, galaxies and stars would not have formed.
mechtech256 i disagree. He is just saying that if you dont have the background, then we cannot have a discussion and their is not point in trying to answer. You first need to go to school and learn the basic. You cannot play basketballs with the pros and understand their techniques if you never played basketball in your entire life. Same thing.

"Because Aunt Minnie slipped on the ice and broke her hip."
jeffy141 Total b.s. The reality is that as smart as you think he is... he didn't know the answer ... not from first principles he didn't.
4:29, I love this line because it shows how people are so unaware of the weirdness that goes on in terms of physics and their daily lives. The simplest of things, "I don't fall through the floor of my house", ends up being a _hugely_ complicated question!
Nah, they are just scared to say "I don't know and my complex mathematical abstractions are really not explanations"
@@jollydove6314 Lmao, the last thing a scientist is afraid of saying "I don't know."
They consistently purposefully move themselves away from the known into the unknown. It's where their work resides.

@@jollydove6314 hey friend can you just clarify where you're sending this message from? Like what device are you using? It seems pretty clear to me that those complex mathamatics actually do explain things. There is so much scientists don't know and probably so much that they will never know. The reason scientists appear uncertain is because they don't make assumptions which is very awkward since it's human nature to make assumptions based on our senses even though our senses aren't absolute.

Professor: Jonny, I did not ask why the magnets do it. I asked about the calculation. Do the calculation now please!
This was one of the most humble and honest responses. Feynman didn’t have the arrogance to say he could explain something as complex as magnetic repulsion in simple terms without also explaining very detailed physics that would take hours of lectures to go into.
Anyone comparing feynman’s response to this interviewer to what degrasse Tyson did to joe rogan is missing the point.
Feynman understands his limitations and can foresee the consequences of any answer he gives. He also made sure he never shamed the interviewer for asking - in fact, it truly is an excellent question it’s just un-answerable in the time Feynman had and with the understanding of physics the interviewer had.
i think i would rather somebody tried to explain it to me, even if i didnt understand the explanation i would at least know that there is an answer
Feynman's answer is actually even deeper than that. He's not saying it's too complicated to explain. He's saying that magnetism is _fundamental._ We actually can't break it down into something else (or at least haven't figured out how to). Our equations just describe how it behaves; none of them answer the question of what underlying cause brings it about. He could say that moving charges generate the magnetic force on other charges, but that doesn't actually say anything about _why_ moving charges generate a force. It's just saying that they do. (And I'm not even sure that's the case in quantum.) Any elaboration he could give about magnetism would just distract from the actual answer: they just do, and we don't really know why. And that at some level of any topic, you have to be willing and able to accept that some things just are to reason and understand at all.
@@discovolante6624 I think the problem is that what the interviewer was asking was too fundamental. Like, if you asked why tides go in and out, someone could give you a very detailed explanation involved with tidal gravitational gradients and Newtonian physics, and it would be complicated and you might not understand it, but you'd know there was an answer like you said.
But asking why magnets repel each other is like asking why gravity exists. The simplest answer would just be to say 'it just does', which was what Feynman did at the start he just repeated 'because magnets repel each other'. Magnetism and electricity are a combined force called electromagnetic force which is just a force that exists within all matter.
Even the fundamental particles that make up atoms have this electromagnetic charge. It's involved in everything that happens almost. Chemistry itself only happens because the differently charged atoms interact with each other in certain ways and make bonds and molecules which includes all of life including you. That's why he also said 'you think magnets are weird but you're not all all disturbed by the fact that your arm doesn't just go through the chair'. This electromagnetic force is what stops atoms from just sliding past each other. The universe itself wouldn't work like it does if there wasn't this force in it. But to ask _why_ something like this exists, it's kind of a pointless question in a way. There are actually theories about how the fundamental forces began as a single force at the beginning of time and then split up into separate forces after the first nanosecond or something but that's probably a disappointing answer for someone who asked why magnets repel.
@@Elrond_Hubbard_1 im not gonna lie, i only read some of what you typed.
@@discovolante6624 allg man. I really should have broken it up into paragraphs.
Feynman really has a passion for topics such as old ladies and ice. Not so much for magnetism.
This is what makes him such a great teacher - look how increasingly enthusiastic he becomes answering the question! He gets really worked up. Just like in his lectures.
he didnt answer anything son
I listen to this for 8 whole minutes !!!!
And I still don't know if Aunt Minnie is better or not !!!!!
What a con!
*Feynman, the Excellent Teacher*
It's lovely how he did not dismiss the question itself, rather asked for further clarification on what the reporter was asking for. Feynman did say _"of course it's a reasonable question; it's an excellent question!"_
A great lesson in infinite regress, critical thinking, and the art of asking questions.

@@j.goebbels2134 One of the founding fathers of quantum electrodynamics didn't know about electromagnetism. Joke of the century.

@@j.goebbels2134 Not exactly, it's more than that. He does/did know, as much as anyone on this earth ever has or could (he won a Nobel prize for the development of quantum electrodynamics after all). It's that it is a question about such a fundamental thing in physics that you cannot answer it in any ordinary way. It cuts right to the heart of the nature of scientific inquiry! It's like asking why things fall down, what gravity "is". Sure you can go on about spacetime curvature and such, but does that really answer the question? It just recasts it in a different framework. Magnets are the same.
"Richard, this is why no one talks to you at parties."
Why?
that and also he's dead.
bc this answer is fucking miserable.
TheSkoobey If you wanted a better answer, go take a physics course at uni.
Clearly his point went well over your pea brain.
I'm a PhD student in the sciences. So... take your European "uni" comment elsewhere. Feynman's answer remains terrible.
Thanks, now I know how to answer that question on my next test on magnetism.
a wise teacher ( Granty ) once told me , actually he was quite generous and told everybody to memorise this
if you don't know the answer to a Chemistry or Physics exam question which starts " why do so and so happen? "
always answer "because it's energetically more favourable "
that way you will always be scored at least 50% and not fail.
In this case it would even have been close to 100% correct.
_Brilliant!_
My favorite part of this clip is around 0:51, with this awkward pause when Feynman creates 'An Explanation' in his head. This is the moment when the next 6 minutes are planned through, and substantial part of his brain may address to other matters.
Surely you're joking, Mr. Feynman.
I feel like you deserve more than just 6 upvotes after 2 years

@Oleg Fedorov It's a small book. Easy to go missing. But still, a great story. I really liked it.
Amazing book indeed
One of my favorite Richard Feynman videos. Makes me laugh several times.
For everyone out there. He actually DID explain how magnets work. In a very tip-of-the-iceberg way. Check 5:35. If what he says doesn't make sense to you, you now understand why he went on to lecture about asking the right questions so you can give the right answers to the right people.
He didn't explain he explained how magnets are made

@@krele14 Not "ignorant" FTFY
@@krele14
"All electrons spin in the same direction" this explains absolutely nothing.
He is not able to tell us why magnets attract each other is probably because he doesn't know why they do.
And that's okay
[Edit]
The reason it tells us nothing is because 1. Atoms and very well explained either and 2. a atom viewed as a very´small magnet itself. So it basically is saying "magnets attract each other because it is full of little magnets.
@@kevinkonig3892 Electrons with same spin avoid each other to conserve energy. What he says explains how, just not why.
Atoms aren't magnets themselves, the electrons that they hold are carrying the electric charge.
You're just projecting your own ignorance.
And that's okay
When each of my children were around 2, I told them there would be a point at which I could not tell them "why", I could only tell them "what". I explained how seeking "why" is what people did when they worked on science, and art, and mathematics, so there is always more "why" than any one person knows, or can know, and that is what makes learning about the world so much fun.
You must have been a great parent 😄
There’s another answer- Find out🖤
Feynman is my favourite scientist of all times. Now, that I am a physicist and have been studied epistemology I can only agree more with him.
So, "physicist", can you answer the question? :-)
He may be a good scientist but he’s also massively arrogant
@@uncannyvally7022 Is he though? He is a self taught new yorker who thoughtfully answered a question in a loud voice. His lectures and notes went out of their way to be made accessible and to break through academic clutter. He brought physics back to every day life. Not that it ever left, but he was an excellent communicator and philosopher of physics and went out of his way to bring humility to his craft. Neil DeGrasse Tyson is more arrogant.

Razendra Bahadur Yep! :D But not only in the most polite and subtle manner possible, it was actually also educational.

Of course it's not a stupid question. It's just the kind of a question that you can't answer in one sentence without "cheating".
No I don't think that he was calling him an idiot. I think that, given the interviewer admits to being ignorant of magnetism, and Feynmann being something of an expert, Feynmann wanted to warn him that given the limited time at their disposal, the answer he could give at that time would be unsatisfactory to both of them because it would be either a glib and cursory answer, or too complicated and jargon-filled (because of the prerequisite knowledge to really discuss such a topic). He was really saying that the interviewer is not an idiot and that he can't give him a good enough answer unless he knows about basics first.
"Uh, Mr. Feynman, we only have 30 minutes of film."

They just do.
vadllens01 why?
sourjello That's just how it is. There is no final reason.

How do magnets work?
Not even Feynman can say. Must be miracles.
It is a miracle. The fact alone equal poles repel each other rather than attract each other is a miracle itself. All praises be to God alone. He alone decides how entities He created shall interact.
no its electrons spin spin interaction.
All magnets have north and south poles. Opposite poles of magnets are attracted to each other, while the same poles repel each other. This is due to the alignment of the electrons' spins in the atoms that make up the magnets. The electrons in the atoms have a property called "spin," which can be thought of as the electrons spinning on an axis, like a planet spinning on its axis. In some materials, like iron, the electrons' spins are lined up in the same direction, resulting in a north pole and a south pole. When opposite poles of magnets are brought close to each other, the electrons' spins in the atoms of the north pole of one magnet are attracted to the electrons' spins in the atoms of the south pole of the other magnet. This creates an attractive force between the magnets, which is what causes them to stick together.
@@ShricharanArumugam95 why do electrons spin, and why do electron spins interact with each other? And why do opposite spins create an attractive force when they are brought together? You didnt explain a thing dude.
@@stati5tik its like feynman said, you can go on asking why and why, but depends on your pre requisite knowledge.
When you ask why do electrons spin, its not like a spining ball, at a subatomic level when we divide the particles into their basic states ( see standard model of physics) we get particles like fermions, bosons, higgs boson and like. These subatomic particle are defined by their charge, mass, and spin.
Now the question what is spin (this inherent property)
Fun question, if we lived in a world where electrons were positively charges and protons are negative charge what would change, the answer is nothing at all. Just maybe our formulas with their signs. Why no change? Because we defined electron as a negative charge. Similarly we define spin of a particle, justify it by showing its conservation of angular momentum.
Eg electron has positive or negative one half spin.
Then we further say based on this spin we can ascertain the direction magnetic field. Based on whether the spin is in the same or opposite directions of two magnetic materials we can say they repel or attract each other.
But now if you ask me why what and where does that invisible Repeling force come from. Then you are about to have your mind blown, Electromagnetic forces act on each other by the exchange of photons.
@@ShricharanArumugam95 youtube keeps deleting my comments.
Why do photons interact with each other in the first place such that they can carrier electromagnetic forces? Why is there a force to begin with? The existence of photons does not logically necessitate the existence of force. We just observed/measured or derived from other observations such properties. The properties are not logical necessarly but rather given. Why?

Everyone should practice asking the question why over and over again on everyday things that normally wouldn't prompt a question.
Yeah that is a decent exercise. But in this case, Feymans ramblings are just a long way of saying, "I don't know," which makes it childish and dishonest.

@@dannybondsofficial well, 8 years later and i can say none of it mattered 🤷♂️
Ok so when you clap your hands, the fact that your hands don't go through one another is because the electrons in your palms are repelling each other.
Now let's get to the bottom of this. What does it mean for electrons to repel each other? Imagine an electron in however way you choose to picture an electron (I like to picture water). Now imagine that electron, which we will call electron 1, coming close to another electron, which we will call electron 2. What happens is electron 1 will start moving away from electron 2, and electron 2 will start moving away from electron 1. So they exchanged momentum. That's important.
Next thing is the electrons interacting. Electrons interact by way of electromagnetic waves. These electromagnetic waves are really just light by the way. So when you clap your hands together, you're making light, because that's how electrons interact. Light is the Wi-Fi of electrons. Whenever something happens in the electromagnetic field, it's because light was exchanged.
Now light is really just photons, so I'm gonna reword it for you:
When electron 1 repels electron 2, it's because electron 1 shot out a photon that contained some of electron 1's momentum, so electron 1 will start moving the other way. Then when the photon hits electron 2, electron 2 will get that momentum, so electron 2 will also start moving the other way.
That photon is called a virtual photon.
I guess magnets work farther distances but exchange less momentum? I'm reaching here but that's the extent of my knowledge.
Yes, despite all the laughs and jokes about it, he told at minute 5:30 why magnets behaves the way they do, but with humility he said too that is not posible to compare it to something your familiar with...
0:48 Feynman is saying that "fuckin' magnets how do they work ?" is an excellent question. He's right, because the "silliest" questions are generally the most complicated ones, and most of people laughing at the famous meme don't know how fuckin' magnets work.
lol the interviewer is a juggalo
why?

Legend!
This can be applied when someone asks you to explain something in a casual conversation. Why does quantum, why does Q.E.D etc...
It's how Feynman would've thought of this rather than trying to explain E,B,D and H fields, he reverts to that point that all children latch on to at some point; the never ending why why why. Which of course is the one question a lot of us do not ask enough. R.I.P sir.
And in the endless why series, he shows that you get to some very interesting things to figure out. You quickly reach areas where, in looking into the question, you find yourself in advanced study that covers multiple fields.
Repeatedly asking why on the slipping on ice leads to the nature of crystals and the structure of the water molecule.
Repeatedly asking why on the magnets leads to electromagnetism and quantum mechanics.
Almost all new science occurs when we explore the boundary of what we know with why or how questions, or find something that goes against a prediction of the current model.
I love how he could have just put the same amount of effort he put into explaining why ice is slippery into answering the question he was asked and he probably would have produced a generally satisfactory answer.
I think you're missing the point. His spiel about ice was to demonstrate that there are levels of explanation within science. Had he finished the point about ice it would have been that water expands when frozen because of electric forces and minimum energy configurations. And _why_ does that happen? The answer would have been the same as for "why" magnets repel. Science doesn't answer _"why"_ questions. However unacceptable that seems to an extraordinary number of people in these comments, that _is_ the answer. Feynman tried to give the interviewer a mini-lesson in the philosophy of science, but he wasn't getting it. In fairness, neither do most people.
Gran video! Sigue así maquina!
What a brilliant mind. That explains how compasses work too
He's an idiot
question: why do magnets work?
answer: same reason why you can't walk through walls
But that would be a lie
"That requires a technical answer."
xamphor That's just the type of non-answer you'd give to a little kid when you want him to shut up and go away. Nice work.

“If you can't explain it to a six year old, you don't understand it yourself.” - Albert Einstein
+DIProgan he explains it though
True Genius. Make even "Why" look so interesting.
True idiot
I LOVE Feynmann. My definition of genius
+Stefan Djusic Me too!
Stefan Djusic "If you can't explain something simply then you don't understand it well enough" - Einstein
even more pointedly, "why" generally presupposes intent, which is not evident in the case of magnetism. "how" questions are always much more appropriate than why questions.
+Volound It doesn't generally presuppose intent. Look, I get that in philosophical, cerebral, academic conversation it's important to have really specific definitions, but it's also wrong to ignore other people's understanding of words. When a layman interviewer asks why he is not necessarily implying "intent". It's a colloquial way of asking how.
***** that isnt the case as much as you would probably like it to be. every native english speaker knows that "why" has connotations that are different from those of "how". it is equivocated enough that making a distinction between them is worthwhile.
+Volound That's why is an atheist asks, Why does there have to be a god? Or Why does there have to be a moral law that was defined from outside of human existence, presupposes the intent that there is a God, so if you don't have a framework of there being a God, you have to understand you can't ask those questions without the inherit understanding that there is a God or higher being.
+Volound You're right. He could have just said, "you're asking the wrong question". Clearly the man had a bit of an axe to grind with the whole Y thing
Well observed. Presupposed intention is the problem here; it's a loaded question and the interviewer also seemed a little demanding and pushy. They were like magnets repelling each other, but don't ask me why.
his last sentence is the point of the discussion ...he polity suggests that a why question requires preliminary understand of the topic
politicians when asked any question
If you don't understand his answer, you don't understand the infinite regression of cause and effect in this universe.
"Why?" is answered using concepts that are already understood to the questioner, and if they aren't understood, then another "Why?" follows. People like Feynman realize that we never truly understand these concepts because they are always built upon something that we don't truly understand.
Therefore the follow-up "Why?" always occurs in his mind and he simply does not know where to start or end in order to satisfy the interviewer.
He doesn't know what the hell he's talking about.
Robert L If you really want to understand his answer, here it is: The electromagnetic force is a fundamental force. No one knows how or why. It just is and you have to accept it.
When he was young, he asked his father why the ball goes to the back of the wagon when you pull it. And his father broke down every reason until it reduced down to gravity and electromagnetism. And why do those forces exist? No one really knows. So no one really knows why the ball moves to the back of the wagon. And that is the deepest understanding one can possibly have of the issue. So when you ask him why electromagnetism exists... Well you've started at the bottom it can't be reduced any farther. So he can't answer the question. Listen again and see if you understand it better now.
The issue is not that people don’t understand Feynman’s answer, it’s that he was a douchebag for giving that answer. He could have given the interviewer the info he obviously wanted, and either ignored the question’s inarticulate phrasing, or concisely & courteously corrected its phrasing (and possibly explored the implications of the different phrasings, if the interviewer wanted to discuss that, too)
Robert L brilliant answer Robert....thanksss brother
The Religion of Quantum has Clouded your mind. Simple answer Gravity=Magnetism.
Feynman: "That is an excellent question, but I cannot explain the answer in a way that would be both concise and scientifically satisfactory without insulting your intelligence with a simplistic analogy."
Half of UA-cam: "WHY WON'T HE INSULT MY INTELLIGENCE? GOD HOW ARROGANT/PRETENTIOUS."
+CarterJ9
That's not at all what happened.
The video is titled "Magnets", but it's really about Feynman struggling with the question of why we feel forces and why there is electromagnetism.
I'm not sure what the interviewer was really asking, but the title promised differently from what we got.
Also Feynman did answer how magnets work (very shortly).
Taxtro he literally says "that's an excellent question" and then puts forth that there are analogies he could make that would not provide a scientifically satisfying answer. That is what he says, and many comments call him pretentious. I'm not sure what you heard. Frankly, I don't care either. Have a nice life.
+Taxtro - ya perhaps... but keep in mind that it wasn't Feynman who was the one who titled it "Magnets"... I believe that was the BBC's doing :)
watch Veritasium and others like him to have your intelligence insulted. At least R.P.F was honest.
@@MrCmon113 go watch a 30 sec video with colourful animations explaining magnetic force is there because electron spinz lolz
Best diversion tactics I've ever seen.
I wouldn't mind watching Feynman go into an infinite sequence of "Why?" questions
Beautifully explained the concept behind "asking critical questions" it's interesting to think of how far down the rabbit hole actually goes. Even though he didn't fully answer the question, most of you upset UA-camr's can google it if you're still not satisfied.
A long way of saying he doesn't know.
I loved this. What a pro. I remember my philosophy professors talking to me like this when I got cocky. lol Thanks for posting this nebulajr it gave my brain a good tickle
Asking "What are magnets" is being cocky?
@@jollydove6314 , but he _didn't_ ask "what are magnets". He asked _why_ they repel. Feynman rightly pointed out that science doesn't do _"why"_ questions.
Love it! I can see the pattern.
But he makes a good point, its just an answer that creates a thousand questions. Questions we've been trying to answer for centuries.
It's the super genius equivalent answer to the annoying game kids always play with you when you try to explain something. Why? As I said, it's due to the nature and context of the topic or content we're discussing.. Why? 🤣👍 Phenomenal clip, a truly profound philosophical and scientific response. Amazing!
Amazing to see how this guys brain worked.
Its funny how I could relate very much to what he said in my own way of thinking and I want to become a theoretical physicist as well. I guess its just some type of people with some type of brain, and has not much to do with where your interests lie. In my family several people independently developed an interest for theoretical physics. Its like this "interest" is embedded in our DNA. But this cant be, because an interest is not something your born with, it develops based on your surroundings. So it can't be just an interest. It must have to do with the way your brain is wired and this CAN be embedded in DNA.
Or he simply dodged the question because he didnt know
He was avoiding the question at first but only to make it more familiar for the person asking it.
@morningstomper123 Absolutely agree. I mean to say: Why is phenomenon A happening? Because phenom B is happening. To some people, that may beg the (legitimate) question, "Why is phenomenon B happening?" Hence, the "why" question becomes an infinite pursuit, and it's only the ULTIMATE "why?" which can't be answered.
"Why?" remains. But in the meantime, we ARE answering WHAT is happening in each step, and our knowledge of WHAT happens grows. That's the perspective of science. That's its domain.
"We don't know" is a perfectly acceptable answer
Not in this case because he did know. For some reason he just couldn't express it right. Very strange, indeed.
Exactly, none of them do. Brian Cox made a living out of saying, "we just don't know."
@@krell2130 Brian Cox is an idiot.
@@schmetterling4477 Its not about not knowing how to express it, its about knowing how much the interviewer doesnt know, how much needs to be explained and the time it takes to awnser a complex question like that.
@@EncovelicusThat's the beauty about the question the interviewer asked... it has a trivial, nonetheless very deep answer that needs no previous knowledge to understand. You clearly don't have the slightest clue about physics. Take care.
Interviewer: How magnets work?
Feynman: I will never answer why.
For 8 minutes
Well put
Dood talks like a prosecutor in one of those courtroom drama shows :)
Neat vid, thanks!
I am here because of Theoria Apophasis. He can explain magnetism. I used to do this on essay questions when I didn't have a damn clue lol....
Lol, that guy is a deluded fool who thinks he knows better than actual physicists whilst only having high school level education! He's a perfect example of the Dunning-Krueger effect.
He answered the textbook answer (that electrons are spinning in the same direction blah blah) but he wanted to explain a much more interesting idea.
What idea was that
excellent video
This is the best answer to the question.
He answered what we know how magnets work, that we dont know everything, that we might never know everything and also answered your "why" questions and gave you a lecture on how "why" questions work. He also told you faults ov cheating by simple analogies that are bad and dont answer the question.
If you find this stupid or feel like he didnt answer the question and that he insulted your IQ then there is nothing to insult.
He gave you "we dont know" answer and thought you something along the way
Was it his "ego" that prevented this quantum hack to give a fucking straight answer, ha? Tell me, what this "great mind" added to the final answer, would you? You're a fucking mindless repeater; just like him...
I watch this every couple years to gauge my ever expanding knowledge. every time I watch this I understand more and more what he means and the sheer raw character that is Richard Fenman
You fucking loser
"Why magnets repel each other?" "We don't know". That would be a simpler answer and perfectly correct and honest.
Me " How do magnets work?"
Richard Feynman: "Fuck dude, I don't know."
for those who are wondering, magnetism is caused by rotations in the aether - there is more to it, but that is the simplicity of it.
but why isn't a nonmagnetic substance influenced within the field ?
nonmagnetic substances are nonmagnetic because aether cannot flow between the individual atoms.
all atoms absorb and re-emit aether, some of the aether leaves at the poles of the atom - this causes the magnetic moment.
the magnetic moment is actually a flow of aether or energy if you prefer, it is possible for this flow of energy to re-enter another atom.
imagine two atoms, they are aligned such that the south pole of atom 1 is facing the north pole of atom 2, in this case, magentic moment can exit atom 1 and enter into atom 2, this creates a larger magnetic moment overall, creating a larger magentic field, you can multiply this by many times and you will get something like a neodymium magnetic.
when you bring a magnetic substance to a non-magnetic substance, it is not that there is a lack of influence, instead, it is that the magnetic moment from the magnetic substance cannot correctly flow into the magnetic moment of the non-magnetic substance, in other words, it is like trying to fill a cup of water by pouring the water into the bottom of the cup rather than into the top (if you pour the water into the bottom, it will just bounce off the surface and nothing will happen).
Bullshit. There isn't any such thing as "aether".
Nice to re-visit this. Reminds me why expertise and the dedicated long-term study required to get it is so valuable-that it unlocks (slowly) more and more complete and nuanced understanding of reality. I'm deeply uncomfortable with the modern tendency to think that everything can/should be deducible through "common sense" and that the average joe is well equipped to discern truth just by applying common sense. My discomfort isn't because I wouldn't want to live in that world (jury is still out, but it would be a more egalitarian place), but because it has so often turned out in history that the simple, intuitive explanation is terribly flawed.
I understand what you meant in this comment. But I do want to add that technically everything is deducible through common sense and in fact has been. But making all of the deductions which were made from experiments and observations over many centuries is not something you should be trying to do all by yourself for everything. Sometimes, you have to stop trying to reinvent the wheel and look up manuals made by people who have already made wheels before.
With respect, I cannot agree with that. You're either wrong or are working with such a fantastically broad definition of "common sense" as to render the term meaningless. Experimental methodology developed and eventually became the standard for scientific exploration precisely because common sense deduction is so fallible.@@sen7826
When you make an electromagnet like in school, you always form a coil shape. Is that because that shape means that when a current passes through, the electrons move through it in a similar way to the magnet he described in the video?
And you thought politicians could dance a wide circle around a question!
-Touche' Mr. Feynman touche'
why is there arguing in these comments? cant we all just sit back and listen to the wise words of Feyman? One of the smartest men of all time
Funnily enough, you would have an equally hard time explaining to a scientist how Juggalos work.
Came here from same song, Miracles
Mr. Feynman - ladies and gentlemen. A life taken too soon, that had so much more to give.
I've got shivers...
Credit to the interviewer - imagine more people like him asking obvious and simple question. The answer was simple - we know how it manifests it's felt but we have no clue what it is
So he doesn't know?
nori, you got it.
I am a guy who digs on science and philosophy, the physical researches, and the metaphysical. I believe in things of a divine, spiritual nature.
Feynman would probably disregard virtually everything I have to say about things.
Still, I did not find anything about what Feynman said here arrogant, clearly, he's just explaining how it's difficult to explain why physical properties act the way they do, especially to laymen such as myself. It's not arrogance to explain this.
Glorious!
A brilliant answer
