In the 62 years I've been around I've had hundreds of teachers in my life. Some were great, some were good, some were decent, and some were terrible. Most were decent. My total exposure to Feynman is through RU-vid videos but I can say without a doubt he is the best teacher I've ever had. During the 4 years I was in college, astronomy, math, and history were my favorite subjects. Am considering finding a way to relearn much of the math I've forgotten over the years just so I can understand more deeply some of the things Feynman talks about. Carl Sagan was another great teacher that I've learned much from. Garnered through the books he wrote and the appearances he made on numerous TV shows. Batman and Robin are supposedly the dynamic duo, but Feynman and Sagan are my dynamic duo. RIP to both of them.
Imagine that there are probably people out there who are similarly brilliant, but did not pursue physics or science, and are assumed to be ordinary people, with maybe a few around them who suspect something extraordinary. Undiscovered genius. I think there are people like this in all areas of life, finding your optimal path in life is very difficult and many things have to come together. Thankfully they did for Feynman.
That is quite right.Genius or great talent is probably more common than one would imagine.But not all of these people can make it to the " top ". There are lots of "undiscovered" extraordinary people on this planet.Frustrating knowledge.....!
The hiding of the logos has been going on for thousands of years and telling the truth will get you killed. When the wizard is handing out brains he gives the nod about universities of great thinkers(something is rotting).
I have a profound respect for this man. Not only is he incredibly smart, but more importantly he is able to communicate complex ideas in relatively simple terms. It seems as though it's so easy for highly intelligent people to make the listener feel stupid (ie: Neil DeGrasse Tyson answering questions from young students in a lecture). But with Feynman, it's almost as if he's encouraging you, on a personal level, to let your mind wander and start asking "why?" or "how?". Makes all the difference
indeed.. but.. I think they absolutely understood what the Spanish were up to... imagine.. they saved a few more... ;~}>>> they were not really primitive at all.. genocide reduced a civilization.. to primitive survival... I have been finding platinum and palladium in the mountains around my house in Arizona.. the history of platinum says the folks in Mexico and South America were using platinum.. but couldn't melt it... neither could the European folks.. I have a hard time in my laboratory.. natural platinum has double double covalent bonds... with palladium.. and.. I can't do it without a plasma torch
This guy had the authority of a white wizard when he spoke. He is not obstinate or foolish, you know he has the permission of his audience to teach them. That 'giving' with good reason is the true meaning of authority, no matter the field. Hmm. In these days and cultures, if you told somebody authority wasnt power and control, they might look at you like you were confused. Lol
He is wrong that the Mayans never used their calendars and math for prediction. That was the entire point. I love Feynman but this is a condescending view of the marvelous advancements of Mayan astronomy and mathematics. The whole point of tracking Venus and knowing how many days in a year and so forth is prediction. If an astrology of gods, good and bad omens, etc., were associated with the emergence of Venus or the disappearance of other planets and stars it was because it coincided with the changing of the seasons. And the ability to predict seasonal changes accurately let you know in advance when you need to plant crops, move livestock from one grazing area to another, harvest your crops, salt and preserve meats to prepare for winter, etc. It was absolutely a predictive science written in the sky and they figured it out. You have to give them credit for that. That is the "why".
He was big on not knowing why or how. He said when asked why magnets do what they do paraphrasing “ it’s the wrong question, if your mother slipped and broke her hip you can break it down but you’ll never know why it happened” magnetic attraction happens but we don’t know “ why”
The notable difference between looking and seeing, the cause-effect difference between continuous connection and snapshot connectivity, in various "mathematical" degrees.. fun to imagine, all ways.
1:58 That part where he goes "wuddawuddawa", my science teacher in middle school did that exact same thing. And he always talked with that same genuine excitement. Man, he was cool.
Sam harris always ask his guest " if you could bring one person back from the dead and give them the benefit of a modern education who would you bring back?" Feynman, is the most common answer. This man is remarkable.
How do you find curvature of space. Let's take a straight line of distance m. Now the maximum bend it can have is my/2π. So ratio is 1to 1/2π. Now what happens beyond that. You have to split space or curl up to a spiral. When something curls it is clustered space and matter condensation. Extreme may result in a dot. Dot is a number. What do you mean by bending just energy storage.
This is great - like getting dope slapped by your Jewish grandfather. The principle that he's dancing around in several of these videos is this - a "theory" is a ricipe, a list of steps that answers "how" something happened. It can't help with "why" questions. Those are the province of philosophy and religion.
Yeah, that's not the point he's making. Understanding the math (or some surface aspect) is pointless if you dont fully understand the phenomenon behind it. The mayans understood the rate at which venus appeared, and could predict it, but that didnt mean they understood it. Religion and philosophy dont help much here. Feynman is warning his students not to become 'educated mayan priests' by learning the equations and shortcuts, you need to forment a deeper understanding Its a theme he visits in many lectures and interviews. Going so far as to say he would ignore the 'names' of theories in favour of understanding the full principles behind them
@@rolandvantol741 he is exercising his freedom of ideas and speech to criticize someone else's ideas and speech. Ever heard about not being discourteous by misspelling somebody's name?
"I was terrible in English. I couldn't stand the subject. It seemed to me ridiculous to worry about whether you spelled something wrong or not, because English spelling is just a human convention - it has nothing to do with anything real, anything from nature."
actually in fact there are 3 1/2 Mayan Codices that remain Now imagine John Lennon if the tables were turned and the Mayans invaded Europe, Middle East and what represented the 'western world' at the time? Imagine if the Maya burned all books in the west except 3 1/2 books? Jewish bIbLE Christian bIbLE Muslim Quran 1/2 book remains of Yoko Ono's Grapefruit LOL
Why do those things predict accurately? Because the things being predicted are performing the same thing as the counting are doing, in the abstract way both are being examined. They are very different physical systems that achieve the same thing.
He knew how to open a hand to the so called "religion-science --["necessary?"]-- dialogue". But I feel that both realms (religion/science) did not listen or just turned their ears somewhere else. For the "extended hand" google THE MEANING OF IT ALL... last page of the book reports a quick response to a religious contemporary text; but there were no ears quick enough in that realm. But the scientific side was/is as slow/shy/foolish? who knows? Just confront wiht Feynman's Nobel Lecture
Michael Serebreny he is from far rockaway queens, not the bx - although maybe his family moved there from the bx tho as it was considered early suburbia.
Who has the closest to this man’ s combination of intellect, erudition, morality, courage and communication skills today, and how do we get him or her elected President?
I wish this video hadn't ended here. What is the point Feynman is trying to make? That all our models are numbers and that we should look at the math rather than try to understand the underlying process?
@astroboomboy I'm not sure if that particular story is true (I wouldn't be surprised) - but a lot of the latter European conquests of older civilizations led to this sort of thing quite a lot. The Spanish were bad, but so were the Brits etc ... and a lot of knowledge from the Arabic world was lost during the crusades for similar reasons ... and in China as well ...
I want to like Feynman (it's not Feyman), and I DO like him, but I just don't get why people think his lectures (judging from the ones I have seen on the internet) are so informative and clever. To me, his presentations seem disorganized, highly redundant, and the points he eventually makes a little trivial. Please don't get all in a huff and make nasty replies, but, from what I have seen, I don't get his near cult status. I would much rather watch videos of Neil deGrasse Tyson and Carl Sagan, who I think are much better at presenting complicated ideas in an understandable, informative, and entertaining way.
in youtube search "Richard Feynman New Zealand 1/4" min 26:10 "explain by a kind of an example... the mayan indians..." Hr 1:08:50 "the mayan thing... numbers were peculiar... [no] explanation" In youtube, search: "Mayan Cosmology Cycle Ends: Precision Cosmology Progresses" Dr. George Smoot talks, in min 11:46 "The Caracol Building / Venus... explanation" Was Feynman joking?
The most efficient way to destroy knowledge by accident or on purpose is to destroy books, a good example by accident is the library at Alexandria. It probably put civilization back a thousand years.
@@tgstudio85 That actually makes sense. Thats why there are some muslims who memorise the Qur'an in its entirety. The people who memorise it are called Hafiz-E- Qur'an. Its a pretty neat system, so even if there are no remaining scriptures in case of some disaster or war or whatever, it's still safe with the people.
There are those who believe that life here began out there, far across the universe, with tribes of humans who may have been the forefathers of the Egyptians, or the Toltecs, or the Mayans. That they may have been the architects of the Great Pyramids, or the lost civilizations of Lemuria, or Atlantis. Some believe that there may yet be brothers of man, who even now fight to survive somewhere beyond the heavens.
Fortunately the Mayans never developed weapons of destruction, or atomic bombs to keep the peace, with the story of security. The Knowledge was transferred, today referred to as Top Secret. So ignorance prevail.
This man is very smart, but I hope I am just missing the nuance or atleast that he skipped the nuance. For physics/science is not just about describing it also about finding the reason. That why we try to relate them to physical principles like how the movements and periods boil down to its essence into forces or gravity or space-time interactions. That is what Newton did when he tried to connect forces to acceleration etc. But here it seems like Feynman said on the end we don't care about the philosophical side or the why. It doesn't matter, it is useless. It all about describing and predicting. My old physics teacher once said that you can never disprove a good theory or prove it (what ever you prefer). Like how you can describe how an old thermometer (with He in it) works by physical and chemical properties (expansion and contraction of the fluid due to temperature) or you can describe it by saying inside the tube there lives a little monster that is scared of darkness and will cuddle up in darkness. But just because you can never prove which one is true, it is useful for extrapolating and describing possible new events.
Feynman would agree with you. What he is trying to explain here is the difference between a model of reality and reality itself. Just because you have a model that gives fantastic predictions doesn't necessarily mean you understand nature. From the perspective of physics the only thing that matters is that the theory makes the right predictions. Different models, however, gives the physicist different ways of thinking and reasoning so they are valuable in that sense. He said something like "suppose you had two different theories that both gave the right predictions. Which one is right? There is no way of telling, not by science. And it is usually possible to show ahead of time that the two theories are mathematically equivalent even though the character of the theories could be very different. But it is still useful to know both theories because a change in one theory that is very simple, would result in a complicated change in the other theory and that the two theories gives the scientist more ways of thinking about a problem and that every scientist worth his or her salt knows 3 or 4 theories for describing whatever phenomenon they are looking at at the time." Watch his 7th Cornell lecture, "Theory, Prediction, Observation" for a more detail on Feynman's philosophizing on science.
he knows that... fer sure and, these days, almost all Americans tell me they think math is hard because our wonderful "free" education >>> teaches Imperial system measurements.. from the Roman empire... imposed on the British who imposed them on us.. to collect taxes... from Roman numerals... with no zero... and.. ladies and gentlemen... it's absolutely impossible to do mathematics without a zero.. and that's why most Americans think math is hard... it's not just hard with no zero... it's impossible
Jesus, of course, had amazing powers. He could fly and pick up really big rocks. He wore a special suit whilst performing miracles, but was an ordinary guy normally.
