Feynman on Scientific Method.

Physicist Richard Feynman explains the scientific and unscientific methods of understanding nature.

[@PRR5406]

"We can never be right, we can only prove we're wrong." Such clarity and humility is what Feynman so iconic!

[@johncampbell3940]

Are we right that the earth is not flat? I think so.

[@johncampbell3940]

@UCm6OZvR_QveiGtwos-qpPZg I think you might be mistaken here. Popper was not a logical positivist, in fact from towardsdatascience.com/logical-positivism-and-the-scientific-method-in-genetic-algorithmics-aaf0ed9d6f22 we get: The non-universality of empirical observation was a particularly vexing problem for logical positivism. Given the verificationist foundations of this movement, only empirical observations made at a particular point in time and space were admissible as protocol sentences. Generalization to other points in time and space was not allowed. This made it hard to prove much of value. Proponents of logical positivism tied themselves in knots trying to address this and other critiques. By the mid twentieth century, the logical positivist movement had largely crumbled and the philosophy of science propounded by Karl Popper had gained traction. so K.P. (among others) put the boots to log. pos.

John Campbell - You’ve phrased it differently. The way to phrase that as a scientific guess is “The Earth is Flat because xyz” and then they go test that theory and it gets proven false. We can never prove the earth is round with 100% certainty. It’s just that theory has never been disproved.

"I read 'em [the letters] to make sure that I haven't already thought of that." In my opinion, that type of attitude is what made him a good scientist.

[@nidurnevets]

My uncle, Abe Bader, was Feynman's high school physics teacher. I remember my uncle describing to my father a brilliant student, who could learn more physics in a weekend than he could learn in a summer. I was only a kid when I heard this, so I didn't catch any name. But the idea of someone that brilliant stayed with me, though I didn't know that my uncle meant Feynman until they both had died, decades later.. I became intrigued with Feynman from programs like NOVA

[@nathanschubert3048]

sounds interesting.

[@nidurnevets]

After Feynman died I got hold the book which is called, I think, "Surely you must be Joking Feynman". In it, Feynman describes what I remembered hearing my uncle tell my father.. He said he lent this brilliant student some graduate level physics books to study, as he was obviously way ahead of the class. Feynman tells the story from his point of view in his book. It's interesting that this particular memory of my uncle talking about a brilliant student stayed with me for so many years.

[@timclaason]

That's really cool. I wish I had family stories like that!

[@nidurnevets]

Thanks. There is more to the story--an unfortunate part. I think it proves that truth is stranger than fiction. If you look up Abram Bader on the Internet, you can usually find a story about my uncle and high school age Feynman, in which my uncle is explaining a physics concept to him. But, if you look up Abe Bader's son Seth Bader, you get news stories about a murder trial. It came as a shock to me when, in 2006, I looked up Seth in the course of trying to write a family history, and this trial came up. My cousin Seth is in prison for life! There is a book about the case called Legally Dead. I don't remember the names of the authors. There was also an episode of a series called Deadly Sins, in which my cousin's case was featured. Abe Bader was married to my father's sister, Yvette. The rest of us are very law-abiding. My father was a violinist in the NY Philharmonic from 1946 to 1979.

[@Sathishkumar-pm8tu]

I am extremely delighted to hear from Feynman's favorite teacher Bader's relative. Feynman has mentioned Bader at many places in his lectures.

I teach research methods in psychology, and this is exactly how the scientific method should be taught. I even use the example of Newton and Einstein to illustrate it (not nearly as well as Feynman does, but I try), and his criticism of many psychology theories are spot on! That doesn't mean psychology is not a science or can't be studied rigorously, just that a lot of it is useless because it doesn't help actually predict anything, especially in the day's of Freud).

[@JD-od6jh]

And that's exactly why I love Feynman so much. I have 0 knowledge about physics (never had the subject). But his idea of how to conceptualize theories and thoughts is intreguetly linked with philosophy and how he percieves the world.

In "The Pleasure of Finding Things Out" there is a wonderful bit of Feynman talking about how the actual safecracking he did was mostly smoke and mirrors: you figured out what two of the three digits of the combination were from looking at the door when it was open, and you wrote that down somewhere. Then you would "get your tools" and retrieve the part you wrote down, try the 100 possible combinations, and then read a magazine for a while because you don't want it to look too easy.

There are plenty of great scientists around today, they just don't get media coverage and generally don't want it.

Feynman was also on the scientific panel investigating the cause of the Challenger Space Shuttle disaster in 1986. He passed away in 1988. RIP 🙏🙏🙏

[@AnnDeschenes]

Brilliant! Feynman one inspiring human.

[@thescientificmindsandmetho7600]

Always best of all physics teachers Mr. Feynmen

[@kuteesabisaso6848]

punchline after punchline... what a great lecture to scientists and non-scientist alike!

[@medickson2000]

I really wish he was my professor. This man has such a way with words. So inspiring! I want to be a theoretical physicist. ❤️

[@infiniteflow7092]

If I could teleport back in time at a place of my choosing; it would be in the classroom where Feynman was giving these lectures.

[@garethwest9069]

If I could teleport back in time at a place of my choosing it would be to when God was creating life so I could take a video and stick it to the 'evolutionists'.

[@gikasmith5511]

Loved his books in my teenage years!

[@dickaubrecht9842]

This a very small part of a series of Feynman gave at CORNELL in the 1950’s. You might want to post all of them. He had a very unique presentation that helped scientists and non scientist to understand the basics.

The fact that this video has no more than 500.000 views says a lot about the times we are living in..................

[@Campbellteaching]

Which year was this recorded? It's superb of course.

[@rvmm2]

Hello John, I believe this was either in 1963 or 1964, it was definitely in the early-to-mid sixties :) Sorry I couldn't be more precise! Thank you by the way for all you have done for the British public and the wider world during this pandemic. Really appreciate your expertise and dedication :) saty safe

[@halwyman]

He was at Cornell from 1944 to 1949, when he took a year of sabbatical before joining the faculty at California Institute of Technology.

[@spyone4828]

My inexpert opinion is Feynman looks too young for this to be the 1960s. And the audience looks very 1950s to me. Feynman was born in 1918, so he would have been 30 in 1948, 40 in 1958, or 50 in 1968. I guess decide which of those he looks closer to to you. ;)

[@danduvall8583]

I would guess 1960.

[@DerKiesch]

In another video covering the first segment of this it was tagged as happening 1964

[@hemendrakumardayabhaimanik2306]

All the lectures of great scientists/men, Feynman specially, on videos ought to be sub-titled for the benefit of all.

[@ihsahnakerfeldt9280]

I would have definitely looked forward to his lectures if I had been a student there.

[@Jearbearjenkins]

Imagine going into university and walking into a class like this. I’d never even think of anything other than the subject

[@sheriffjohnbird3179]

This is a great example of why Feynman is adored by scientists.

[@cynthiaklenk6313]

Once again Dr. Feynman lays it all out - simply and elegantly. Folks who think "politics" (a human construct) has anything to do with this methodology (for that is what it is) misses the boat - they do not understand or they have been mislead, and likely had failing grades in all of their science and math classes in high school, or one or more of their teachers failed them in comprehending the scientific method and simply passed them.

[@TheAtheist22]

Professor Feynman. What an Incredible mind.

[@scottwebber4540]

I wish my science teachers were like this man.

[@ColonelFredPuntridge]

If they were, they probably wouldn't be your science teachers.

[@KingTranscended]

I ike the fact that he states that a theory is never right but rather has not yet been proven wrong. Which is key because it will allow for less resistance if or when the theory is proven wrong.

[@MumblingMickey]

+Mr. Transcendence A theory is a body of knowledge... its not a single statement that can lend itself to being disproved or proven. Laws and principles however are proven or disproved.... there is resistance to a law or theorem being disproved not from scientists so much but rather from nature because technically its not possible.... you can't undiscover axiomatic facts.... nobody will ever discover that Archimedes principle is not the case... once its found to be the case thats it...case closed. However we MIGHT discover a new material with properties that allowed for a higher upward force when immersed in water.... and this might be then added to the theory of fluid mechanics. So newtons laws even though technically not completely accurate are still part of gravitation theory... but Einstein or Laplace or Gauss discovering that they are not completely accurate does not mean gravitation theory is wrong.

[@MatthewBerginGarage]

+MumblingMickey "but Einstein or Laplace or Gauss discovering that they are not completely accurate does not mean gravitation theory is wrong." Sorry if it is not completely accurate then it is wrong. It might still be useful but it is still wrong.

[@JorgetePanete]

@@MumblingMickey Check your grammar.

[@davidstorrs]

How amazing is it that a theoretical physicist got letters about his work sent by lay people? Feynman was a legend.

[@ezbo1883]

9:44 " i read them to make sure" this is a very clever sentence in that it points out what his actual intentions are in his work, as a scientist or whatever you might call someone like Feynman.

[@4rLWeSFHRggQ]

Physics stays the same, only our understanding changes. Too bad there are many people like you who don’t notice the very important distinction.

[@samanderson380]

what an intellectual giant.legendary teacher

[@c0wbait]

I've never in my life used my "i'd like to like this video more than once", but here I am begging

[@gdwnet]

09:00 wonderful finish! Love this guys mind.

[@MDMAx]

"You're giving the psychological matter to things that can't be described so precisely. Yes. But then you can't claim to know anything about them." 6:33

[@feisalmohamed9797]

No, he said you are dealing with psychological matters and these cannot be defined so precisely. The psychological matter he refers to is the hypothesis of how much love is sufficient in explaining why the child hates the mother. Feynman here argues that you cannot attach a numerical value that would necessitate a certain conclusion and would be the only plausible interpretation of the consequences or the results. Of- course love cannot be defined in such a manner therefore Feynman here suggests we ought not claim any scientific knowledge on it.

[@joelamoako6778]

i understood in 30 seconds, Richard Feynman is a Legend

[@lesaztec5]

relate to the physical reality of most humans is what he does best. He is a true genius.

[@arguanmodeth]

We need the complete lecture. And what is with the low number of likes? This is brilliant.

[@svvramprasad]

When science meets showmanship!
