      2. When after 8 years of genocyde Russia comes to Ukraine to stop it, call it a fascism, sanction the use of TPU

    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.

      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
      @tomasusan 10 лет назад

      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
      @ArbitraryxIntentions 10 лет назад

      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.

      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
      @CataclysmZA 2 года назад

      > 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.

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.

    Richard Feynman's lecture on "Computer Science Hardware, Software, and Heuristics" was delivered in 1985, and although it was focused on the state of computer science at that time, there are some ideas in the lecture that could still be surprising to computer scientists today. Here are a few examples:
    1. Emphasizing the importance of hardware design: Feynman stressed the importance of hardware design in creating efficient and effective computer systems. He argued that software design should be driven by hardware capabilities, rather than the other way around. This idea was somewhat ahead of its time, as software has often been seen as the driving force behind advances in computing, rather than hardware design.
    2. Discussing the limitations of algorithmic approaches: Feynman discussed the limitations of algorithmic approaches to solving complex problems, arguing that sometimes "heuristic" or intuitive approaches can be more effective. He suggested that computers could benefit from incorporating more of these heuristic approaches, rather than relying solely on algorithmic methods.
    3. Raising concerns about the impact of computing on society: Feynman raised concerns about the impact of computing on society, arguing that the rapid pace of technological change could have negative consequences if not carefully managed. He suggested that computer scientists should think more deeply about the ethical implications of their work and take responsibility for ensuring that technology is used for the benefit of society as a whole.
    Overall, Feynman's lecture was notable for its emphasis on the importance of interdisciplinary thinking and its recognition of the complex relationship between hardware, software, and human intuition in the development of computer science. These ideas remain relevant today, and Feynman's insights can still offer valuable perspectives for computer scientists and others working in the field.
    There are a few points in the lecture where he touches on the potential societal impacts of computing:
    1. Automation and job displacement: Feynman briefly mentions the potential for automation to displace jobs, though he notes that this has been a concern for centuries and that new jobs will likely be created as old ones disappear.
    2. Computer addiction: Feynman expresses concern that people may become addicted to using computers and that this could have negative consequences on their social and emotional well-being.
    3. Impact on privacy: Feynman briefly touches on the potential for computers to be used to invade people's privacy, though he notes that this is primarily a social issue rather than a technical one.
