By the way, Feynman technique is not perfect. Brain-storming by this technique will make students thinking at everywhere. Hence,Circular reasoning is more feasible.
This why means a good way to inspire students to understand a concept by themselves. learn it by yourselves. Step by step. Also,answer is made by yourselves. Exactly,it is your own answer.
This is what legends are
Found the bridge that connects science and philosophy.
Can you live without interactive encouragement ..... And still feel like you can deceive ... No arrangements necessary ..... Then you will realize what it's like to just live Without an interactive stage of confusion... More matter of possession.... Position or any other suit .., mental cases of observation Conclude possessions Hypocrisy Mental construction of attitude or hate in the matter of confusion Due to the synthesis Others may not be able to regard it's coolness it's fairness Which is obstructing something it likes Feelings are a large part of a human character To say something wrong to the human character or do something wrong to the human character Sometimes it is permissible or understood If you ever had to punch somebody in the face and it got that bad were you actually did it you were probably not involved or under the circumstances ... Circumstances are you pick something weaker or something irrelevant ... People are cheap they are not stronger They cannot get in positions higher than the position that they are Victims are the weak ... And have false pretense about Laws and regulations .... But they are forgetting the character amongst its top .... And perhaps The forbidden life that lives amongst the others ... Feelings are exceptional But they should not be kept as you should know doctor I should not ignore them .... In a lot of cases they are ignorant for the same As a blabbing child Anyone suitable will be unsuitable to speak ..... Irrelevant characters with unsuitable feelings will interrupt that .😊 Some people cannot be understood that way The interrupter didn't know his self While trying to conclude for everything it feels Even your job or the references of things you care about comes in everything you think It repeats in everything you do Best protection is not my wisest If you are my enemy But as an enemy it is best To say what you think is wise ... As one who cannot take your result It's best I raised the spear
Job.., attraction, place,and things invaluable ...not a magnet
Sir, i asked if you want sugar in your coffee.
God what an amazing teacher he is....thanks to the uploader many others can benefit from this..
Thanks
physicist has stroke abt magnets
What he meant is don't ask why, ask how
This has to be one of the coolest videos on the internet
And if you cant explain it with the child-like simplicity there is. You probably don't know it...
HAHAHAHA, I don't think so. He simply just was honest to the person asking. Some things are hard to explain to be understood by other in its true nature.
Nope, some things cannot be explained further. Some things are because they are.
As an adult we have the "why" inquisitiveness knocked out of us because admitting you dont know something is seen as a weakness in modern society.
"I don't know!!!!" All he had to say
The truth is physicists don’t know why. They still don’t even know what light is.
Seems to me like a pretty straightforward jerk.
Magnets bitch!!!
He seemed like a twat
Hi
Sub texts: **scientists don't know how magnetism works.*
This could trigger an existential o.c.d that could drive you mad ! Asking too many whys that is
Why is ‘why’ why ?
This isn’t Richard Feynman, this is Grandpa Simpson. “C would usually follow…”
A seven minute video to say that he can't explain magnets, Richard feynman is a pretentious babbling moron, fifth grade science fairs do a better job.😂
You're a moron if you got that from this explanation. The idea is that any sort of explanation in terms of something familiar would be unsatisfactory because magnetism is a more basic/fundamental part of our reality than most of the things we are familiar with. You look at the reason you don't fall theough your chair, you look at the reasons that your table doesn't fall apart and you kind of internalize that as part of our reality without questioning. "Of course we don't fall through our chair! It would be ridiculius to think otherwise." When, really, the reason you don't fall through your chair is due to the same force that causes magnets to repel. The fundamental truth isn't the chair keeping you in place; that is a consequence of the more fundamental truth of magnets repelling. If you try to visualize the magnets working by some kind of elastic band or some thing bouncing off of something else, you're performing a sort of circular reasoning because balls will bounce because of electromagnetism, rubberbands pull back because of electromagnetism. You can explain magnetism in terms of more fundamental principles if you want, of course. You can try talking about U(1) Yang-Mills. You can talk about Lorentz Invariance relaying charge to current, electricity to magnetism. But in some sense, the character of the law that causes magnets to work the way they work is almost axiomatic within our universe and you might as well be asking why is 2+2 equal to 4.
A genius I s just a complete pathetic person incapable of normal function but we make allowance for the little guys like Sheldon Cooper, this guy needs a padded toom
And this is why we all know books smarts are the exact opposite of a person with any sense Richard should be in an asylum
The guy wouldn't ask why his cup on the table doesn't fall right through, yet it is just as surprising. The real question is, why do you find it strange that the magnets repel?
I hate having to dumb down my explanations of things for normal people
Go to the library and get the making of the atomic bomb. Brilliant book. This whole series worth a watch or 3, cheers
Good answer. Lets keep these plebs guessing hah
Sounds like one of those current BBC journalists who love to interrupt alot, "It's a perfectly legitimate question". (So whiney). I think the good Professor can be the judge of that.
So this is where Neil gets it from
What a thought.
This guy should be stripped of his pocket protector ! Or put on his glasses, so he can see what he is saying is all wrong ! This guy sounds like Marty Feldman ! 👀
Try blowing cigarette smoke between the two magnets ! If there is a field present, then it should be impossible for smoke to pass ! Yes or No ?
Why don't he just say he doesn't know ? Instead of deflecting ? 😂🤣😂
Wife: do you love me ? Me:
i recently had to help a cousin of mine with his 6th grade project on magnets i was writing an introduction to how magnets work and it was super difficult to explain without talking about electron spins and orbitals and domains of a material... i resonate with what he said alot especially when he talked about cheating the answer with an anology. rip richard
That smile in the end though
wow! Just wow! such a explanation
The real question is why is he sitting in such an ugly chair
DAMNNN BRO JUST SAY I FORGOR
/iamverysmart Stick with "deeper explanations require deeper knowledge of physics" and steer clear of the lessons on the nature of knowledge itself better left to epistemologists.
He’s kinda slow
In other words, you’re too thick to understand this…
Niqqa life aint that complex
It’s always so nice to listen to a clear mind
