Introduction Article to Heuristics and Metaheuristics: muonray.blogspot.ie/2016/04/me...
Richard Feynman, Winner of the 1965 Nobel Prize in Physics, gives us an insightful lecture about computer heuristics: how computers work, how they file information, how they handle data, how they use their information in allocated processing in a finite amount of time to solve problems and how they actually compute values of interest to human beings. These topics are essential in the study of what processes reduce the amount of work done in solving a particular problem in computers, giving them speeds of solving problems that can outmatch humans in certain fields but which have not yet reached the complexity of human driven intelligence. The question if human thought is a series of fixed processes that could be, in principle, imitated by a computer is a major theme of this lecture and, in Feynman's trademark style of teaching, gives us clear and yet very powerful answers for this field which has gone on to consume so much of our lives today.
No doubt this lecture will be of crucial interest to anyone who has ever wondered about the process of human or machine thinking and if a synthesis between the two can be made without violating logic.

“One of the miseries of life is that everybody names things a little bit wrong.” - Richard Feynman 1985. A more profound statement than one might think.
Good thing he didn't experience social media.
At first, I thought it meant that everyone nit pics little things you say. I get it now.
Indeed. 🙌❤️🔥
0. Sponsor a neonazi and neofascist government in Ukraine with swastikas, etc.
1. Force the whole world believe the AI == the TersorFlow+TPU and buy it
2. When after 8 years of genocyde Russia comes to Ukraine to stop it, call it a fascism, sanction the use of TPU
3. PROFIT
People change and swap the meanings of words to the opposite not only randomly but for profits. Especially when it's done by imerialist country with eternal racism issues.

In this lecture Feynman covers:
- nerd t-shirt trend [0:01]
- the Universal Turing machine and complexity equivalence (automita theory) [34:57]
- binary search trees [19:03]
- short term memory addressing (RAM) [22:22]
- long term memory addressing (HDD) [34:28]
- the CPU registry instruction pointer [16:18]
- early character sizes and pixels [25:07]
- logic gates (transistors, "and" and "or" gates) [28:57]
- parallel computing and read write locks [38:48-43:28]
- limitation of DFA [43:30]
- greedy algorithms heuristics to estimate non linear problems [45:08]
- pattern recognition [57:42]
while preforming high order binary arithmetic to create perfect examples that make it simpler for the audience to listen.
You can easily see how he is influenced by his time on:
- the Manhattan project (his team of simulation modelers using card systems)
- his time looking trying to save the engineers in the Manhattan project (the faulty architecture of liquid valve)
This should clearly be the “top comment” but since youtube reflects our society instead of an ideal of one, we have a comment related to glasses. Thanks for the toc, friend.
This should be pinned
@@mirceavasiliniuc7578 lmao I found the bluntness of this comment hilarious.
@@mirceavasiliniuc7578 making people laugh is more important than organizational time stamps.
@@canIeaturcarrots so you don’t like being paid for your work?
This was 1986, when he was 68, 2 years before his death. Imagine your grandpa being this smart, this funny, and this right. And imagine that 30 years after he explains new technology, still most of it is spot on. What a guy.
Principles are the real knowledge, not the ephemera of particular technologies.
He was, died something like 2012 though and didnt quite win a nobel.
@@musicalfringe Thats right.
@@ericcricket4877 are we still talking about Richard Feynman who died in February 1988 and got a Nobelprize in 1965?
@@baoboumusic My grandpa.
Richard Feynman always uplifts me when I feel down :)
+Adikshith Ojha oh He does the same for me :)
When I listen to him, I'm listening to a genius, we can't do that to so many geniuses already gone like Newton and the like, it really upsets me Obama got a Nobel prize, the prize is suppose to be giving out to geniuses, like mr. Feynman.
+Ranjit what did obama get a nobel prize for?
+gray scale that is my point exactly, he doesn't deserve one.
No...I asked you what he got one for
He's a natural - so entertaining.
I don't care about his nobel prize the man was born to teach!
After they gave a peace prize to Arafat, to some crazy leftist environmentalists, and to Obama a few weeks into his first term, I lost any respect of Noble prizes of late.
@@mohammedjelloo8023 that is is to say; do you have anything to add?
im pretty sure he didnt care about his nobel either.
I'm so thankful that Richard Feynman was recorded so often. Now I have his tapes to learn from. He makes things so easy to understand and inspires me to learn because of his enthusiasm for the topic.
Thank you for posting this. I am someone who never did well in math and science, but have a deep appreciation for great thinkers like Feynman and a desire to always learn more.
I love that ending line, "So I think that we are getting close to intelligent machines, but they're showing the necessary weaknesses of intelligence."
His analogies and delivery makes him one of the best teachers I never had. I bet he would marvel at the technology that is accessible to the consumer today. He has just great character, you can hear it in his voice
I may upload the other lecture on nanotechnology, done by Feynman a year before this, soon.
please do
Did you upload it?
@@user-lw5oc1tt8k yes, several years ago - if you search Feynman tiny machines aka there's plenty of room at the bottom.
@@MuonRay great thanks
I don't usually clap at the end of RUclips videos. But, when I do, they're almost always of Richard Feynman.
Thats funny. care to share what the other videos might have been lol?
Yeah, seeing as you like Feynman I'd love some recommendations on interesting videos to watch
cringe
who claps alone in their room watching a computer
Feynman was amazing, people are laughing and entertained while he's talking of machine language and registers!
I've only just recently heard of Richard Feynman, but I find myself wanting to watch as many of his lectures as I can. He seems like the best teacher that I never had.
-bill gates
This lecture IS a summary of how computers work. He explains in layman's terms so the average person can understand or at least begin to understand.
He should be awarded a Noble Prize for teaching.
I'm currently in the middle of an A level electronics course, and it's fascinating hearing Feynman explaining logic gates in such a novel way
Without a doubt the best lecture I've seen in Computing. Would never bunk classes with a lecturer like this
Godbless Feynman , AND the human that filmed this , just to think if he never filmed this we wouldnt have it , people often forget how much of an effort filming was back then , cost of batteries , cost of tape , they were bulky etc etc
This guy could talk about the in's and outs of a cats arse and I would listen with the upmost respect and gratitude.
This awesome human known as Richard Feynman.
absolutely correct
Basically, yes.
He'd need a map of a cat to find the arse.
I so see what you did there.
is it a brown arse or an orange one?
Thanks for uploading this. It should be noted that, in the problem of getting 64,000 processors to work together on The Connection Machine, it was Feynman that figured out how to do that, and make it work, not some computer geek.
such a great explanation of a computer. feynman was the master of making some very complex material digestible to the masses in such a unique viewpoint.
Love conceptual thinking. It is the best dish. Feynman's humor is delightful.
Another brilliant lecture by Mr Feynman. Thanks for providing this material.
Feynman's response at 1:03:27 is nothing short of prophetic.
What was the guy's question????
@@samhangster Probably asking about government controlling the population by machines (big brother program).
i wish to no end that i was old enough to have lived at a time when i could have met this man. if half of our teachers were half as passionate and adept in their fields as this man our nation would be number one in education. of that i have no doubt.
Of course you're right about that. He was a genius and won a Nobel prize. You can't expect half of our teachers to live up to that but I agree it would have an amazing impact!
Very true. In most physics courses you will come across 1 or 2 really talented electronics and computer gurus that can build a microcontroller in their sleep to hook up to an Analog to Digital converter. At the same time you will find they often have advanced theoretical skills who are good at computational simulations and mathematics- Feynman had both of these skills, mechanical and theoretical- he also enjoyed experimenting, which is rare for a theoretical physicist but not unheard of.
That remember me about Fermi as well was a theoretical physicist with a taste for experiments.
He was quite lousy as an experimentalist actually, he has dabbled into it of course, but he was no Fermi. Not necessarily due to lack of understanding, but due to fucking things up quite often.
This is actually a masterclass in teaching, using the subject 'computer science' as a practical example. :)
The absolute ultimate explanation of how computers work. He does it backwards. Could someone wonderful person please make a short animated version of this. Maybe it would lead more people to feynmans speech
Everything he said in this video was exactly what my Information Technology teacher said and showed us in class at my TAFE community college back in the late 90s, here in Melbourne, Australia 🦘🇦🇺
I think the 90s would have been a great time to be learning about this topic so its good to know that this video had some similarities with your studies.
This lecture shows precisely how amazing a teacher Feynman was. For a leading esoteric theoretical physicist to explain technical subjects to layman, he did a tremendously fantastic job. Everyone who aspires to become a teacher should surely watch him teach with passion, simplicity, and organisation.
Back in 1998 my highschool math teacher was a big fan of Feynman. Needless to say, he was a great teacher. Just too bad I was a bored stoney highschool kid lol. He managed to inspire me to study physics though, so that was a good thing.
Thank you for making this available to the greater public. I would have loved an updated lecture where he explains deep learning and the future of AI.
Newer herd better and funnier description of a computer principle. Feynman really was a teacher extraordinaire.
i lost count on how many times i read " surely you are joking mr feynmann" .. may be 100 times... but each time it is so interesting..educative..RF is one of my most favorite teachers..
"You shouldn't treat knowledge like it's a competition."
Can we be friends?
@Kalergi is trash gg
How is competition defined ... Its a function of time ... And we don't live for millions of years ...!
Thank you for a good learning lesson with respect to the good concepts of computer.
such a great lecture from a very rare gifted person should have been matched with precise close captioning for future generations
Amazing, Feynman is always a pleasure to hear. Thanks for posting!
This is fairly brilliant. Pretty funny in parts too. Feynman is a great speaker.
This video was recommended to me by Ashok Rajagopal… awesome lecture 🌷🥰
He's probably the best teacher I've ever seen.
Jonathan Abbey He is awesome! I have admired him since the Challenger example where he did his experiment for the committee. What a great, great man. RIP.
Love his humour. It's also crazy how the heuristic idea of intelligent machines is what we are seeing today with AI, having overcome the problem of huge computing power.
This is a fascinating lecture! It definitely illuminates the improvement in computation when we compare this technology to what we are achieving today.
It's essentially the same now as it was then.
I would prefer to go to theater and watch this video instead of watching Fast and Furious or any other hitting movie. Feynman makes complicated things very simple and funny to study.
I would argue that he doesn't necessarily make a subject simple, but makes that subject simpler.
Brilliant talk. The ending in particular.
At 1:08:35 Richard tries to put his glasses on the shirt pocket and realize he has a t-shirt and then make a move as if he were going to polish his glasses, LOL.
LOL fast reaction
Good recovery though. Lol.
Fuck me, I do this shit all the time, God I'm an idiot, though...
Dick! :P (If you know what I mean)
a genius in every way possible
If you told Richard Feynnman that you can store 500 GB in a pocket. He would like it but he would NOT be surprised at all. Because, we are still trying to catch up to his vision. His vision is far bigger than our gadgets today. Back in 1959, Richard Feynnman presented his vision which made him the father of Nano Technology. We are still working on it. Search "there is plenty of space at the bottom" and see that lecture also.
i really do think that feynman is among the top 5 intellects in the history of the human race.
Don't know about that... But a whole lot smarter than I!!!
*Top 10 (not sure tho)
This guy is so imaginative
Dick Feynman: the man, the goat, the legend.
'Just love watching and listening to him.
This has helped me understand so much more about exactly how computers compute information.
Great lecture! Note that the (incomplete) explanations took more than a few minutes.. : )
Thomas Calloway
True but unlike when most people give their explanations. Every single word of his gave more insight into how it worked.
Where as with others, they can spend an hour explaining something to you, yet you still feel like you've gotten no where (because that's exactly the case).
There are times where I have to spend hours just asking the question to people. Because they still don't get exactly what I'm asking. They think I want to know how a transistor works, or how an operating system works, Or what machine language is, or some other BS.
When all of that, *_does not matter_*. And the great thing is, this guy explained that, right at the beginning of the lecture.
His whole lecture was explained so simply, that I think honestly a kid could have understood it (which is what I think Einstein was alluding to in that famous quote of his).
I really wish I could have meet this guy in person, I *_really really_* do.
I could spend hours, days, weeks, just listening to him talk. Absorbing every bit of knowledge he has to offer.
I only ever really feel this, when conversing with physicists (which he is), they get down to the most fundamental aspects. They explain from the bottom up, not the top to bottom.
They explain in a way, where if they said something to you, then left you to your own devices to think for yourself. You would understand more on your own, without having to retrieve more information from others.
It's like stacking cards, but they help build your structure, but in such a way that you can continue to build it on your own without anyone else's help.
I don't know if I am making any sense.
I'm sure part of it is that Feynman is a much better teacher...
I also think your question is too high level (and vague).
I saw an interviewer once ask Feynman why magnets repel and he spends fifteen minutes talking about the problems with answering high level questions. You've probably seen that interview.
Thomas Calloway
I think the problem is that people are not willing to admit that at the very core, they don't know.
I have asked that very same magnet question, and what you get are people talking about fields and how they warp and etc etc, over all a bunch BS.
I also wouldn't just say he's a good teacher, I would say he understands the concept more so than others.
I also don't know why you guys refer to these as "high" level questions. When I see them as the exact opposite, as the most basic fundamental of questions. That everything else it built off of.
Its like the question I wish to ask, why do electrons repel other electrons, and why do they attract towards protons?
No one knows the answer to this question, yet I'm sure there is someone out there who will try to give an hour long explanation on it.
Roshawn Terrell
Something for you to think about..
Feynman understands the nature of electromagnetic forces as well as any human who ever lived and he is bothered by the "how do magnets work" type of questions.
I understand computer engineering much better than Feynman (my entire PhD focus) and I am bothered by the "how do computers compute" question.
muon, you are my best friend on youtube, though we have never met :) Thanks for the upload man, pure gold
God…this is gold mine…thx a zillion for uploading this…
Imagine if he were alive today and what he could explain now! Even though most what he said is relevant, we have made truly amazing discoveries in physics, and machine capabilities.
I didn't know this existed. This is incredible. Thanks for sharing.
superb content....timelessly relevant....a historical gem 4 sure
The end of this lecture, the last anecdote he made, is absolutely gorgeous. It brings all the reality of what intelligence is compared to the vast immensity of problems, by a single paradoxal counterpart similar to ego. Our easiness in solving things by patterns and prediction, is also what can make us fool or at least it can give birth to a bias (correct me if I'm wrong).
> Our easiness in solving things by patterns and prediction, is also what can make us fool or at least it can give birth to a bias (correct me if I'm wrong).
A bias is just another version of heuristic 693 creating a positive feedback loop (which is itself a stable condition, respecting the laws of entropy). But the conditions for creating that positive feedback loop are incomputable. We can recognise the pattern of how those biases came to be, but we can never predict someone's bias based on a limited set of information about them. Our own intelligence has fundamental limits to the strength of our predictions.
Spying apparatus, for example, that aims to tag you if you're a radical going against the government's interest, do not know anything about you. You need an enormous amount of data about someone to make a computer determine if they would become a mass murderer, but we're fooling ourselves into believing that a dumb but very fast file clerk can predict human behaviour when humans can't even do it themselves.
Minority Report suggests that the only way this works is if there's a supernatural force at play that links multiple human intelligences together to have enough power to make the prediction. But even then, Precrime cannot predict the spontaneous behaviour of humans. It can only look at things people do that leave a hint of future plans, and act on those.
The same fundamental limitations to computability in weather predictions apply to anything that is affected by entropy. Reduce the size of the problem and it is computable. Trying to predict human behaviour with something other than our natural intelligence requires vast amounts of power.
I could weep watching this. We need a lot more file clerks like RF in this world.
this is exactly the way it works down low, on the metal. and even in the low level programming.
I love Richard Feynman, One of my Idols
uplifting indeed. I admire your style!
A great man, scientist, thinker, and human. We could all learn a great deal from him. A great book about him is “Genius: The Lifevand Science of Ricard Feynman” by James Gleik ... Tuva or Bust!
thank you so much for uploading this.
although he is before my time, from everything i can tell, mr feynman was something special.
That is somewhat of an understatement. :-)
It is an honer for all IT community that Feynman someday had talked about computer internal processing .. I am proud being an IT person because of that.
how does he do it ? he makes everything so lively and delightful ! What a great spirit!
Richard Feynman is soooo cooool. Computer science is amazing. Feynman was universally regarded as one of the fastest thinking in his generation.
great lecture from a great mind.....
it's amazing how relevant some of these questions which they discuss at the end still are today (2019). especially the big brother threat tha computers may bring...
Am totally into this person ! Richard
54:24 "Machines arent replicates of nature, but a implementation of it using different materials"
57:40 "What are humans better at?"
Art, philosophy, modelling, analyses, design, cosmology,,,,
great man, makes you feel that you are smart,and I love him for believing that, things are not hard to understand but are just a bit complex.
Feynman would be blown away by modern computer vision. Self-driving cars, fingerprint recognition, distance finding with augmented reality, and more!
Thank you verry much for uploading this. Wish I could understand the questions at the end.
Pure genius love this guy
souhaite que je le connaisse plus tôt. quel professeur fantastique
ملهمي وعراب فلسفتي في الحياه ،، شكرا فايمان 👍🙏🏻💐
I wish he was alive now. He’s talking about how big a Kb is and now we have terabyte memory that can fit in a pocket.
This man is my all time favourite human being
5:32 In Turkish "Bilgisayar" means the computer which can be divided into 2 part. Bilgi: data/information, sayar: counter, data counter.
Got here to watch this video. Saw your uploads. Subscribed.

This might be a new form of education, stand-up education. Amazing! :) Who could guess learning can be so entertaining after coming out of a public school.
love listing to RF lectures... he sounds like a goodfella..
Great...I feel like the dude is right here in my living room having a beer and smoke and explaining all this to me in easy terms
Best thing on youtube.
Almost unbelievably clear lecture
Please do, I would be quite grateful. 'There's Plenty of Room at the Bottom' still fascinates me to this day - I'd love to listen to his ruminations on the subject decades later...
This is my very favorite youtube video.
The thumbnail for this is fantastic
Simply, thank you.
Great Thank you :) Hours of insight and fun :)
Anyone who likes this video would probably love the book “Surely You’re Joking Mr. Feynman”. Until reading I had no idea he led such a jaw-droppingly full and interesting life.
I'm so happy he skipped the slides to tell that amazing story at the end
"the key to it is dumber but faster" haha the "Forrest Gump" class of algorithms
A genious like Feynman only appears one each 100 years, we need to whait for the next one.
Well you definitely need to whait
Lol only a joke
roner61 Dyson, Hawking, Susskind, Witten, Penrose, too many to list. I love Feynman, but science is a cooperative enterprise "on the shoulders of giants".
***** Too many to list..
The future is now, my dear old Feynman. Wish you could see.
I often marvel at how men like Richard are able to stay sane: Then I remember thats what a fraternity is all about; support and sharing ideas:
What?
JDR I also was like: what?
