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.

[@alirajabzadeh8076]

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 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.

[@Paretozen]

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.

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.

[@bogbody9952]

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!

[@MuonRay]

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.

[@hrivera4201]

That remember me about Fermi as well was a theoretical physicist with a taste for experiments.

[@mikhailmikhailov8781]

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.

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.

great lecture from a great mind.....

[@ArbitraryxIntentions]

This has helped me understand so much more about exactly how computers compute information.

[@tomasusan]

Great lecture! Note that the (incomplete) explanations took more than a few minutes.. : )

[@ArbitraryxIntentions]

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.

[@tomasusan]

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.

[@ArbitraryxIntentions]

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.

[@tomasusan]

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.

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).

[@CataclysmZA]

> 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.
