    This is without doubt, one of the greatest TED talks of all time. 99% of TED talks are trivial.

    What a likeable and knowledgable guy! Two things that unfortunately not often go together.
    This is one of the very few modern TED (as opposed to the original 80s TED) that is actually good, and gives food for thought on many different levels.

    Great talk! He managed to explain such complex topics so that almost anyone with a computer could understand the potential of analog computers.

    Wow, what an awesome lecture. He definitely shifted my perspective on computing. I guess my cells are skilled at low accuracy differential equations while my brain is thoroughly unskilled at high accuracy ones ;)

    What a great talk, too bad RUclips's algorithm doesn't like it.

      A fish does not know water. Does the algo know that there is a choice? Not unless it has tasted some analog.
      The fish will only know water if it gets out of water occasionally. A man who loses a leg is more aware of steps than one with legs. (Marshall Mcluhan)

    This is a really neat and interesting talk. Although, as easy as it is to point out the flaws in modern digital computing, it is also easy overlook that analog computing is arguably still built on a countable alphabet.

      You're aware that numbers came first, not the alphabet

    • @balapillai

      What might an alternative to analog being built on a countable alphabet be? What else other than a countable alphabet could it be built on?

    to synth a cell by introduced CPUs building pop nano constructions it would generate powerlessing pop cells. at wave equation it's dropping energy also radition into this loss. on this CPUs you can get plants producing energy in spacecrafts. try inverting peaks of energy consumtion in biological lifeforms in model.

    @factsheet4930 3 года назад +2

    But actually, the Quantum computers he is talking about, are considered digital!
    As you can only measure a 0 or a 1 in the end, you don't actually have access to the analog possibility and they happen in the background during the calculations!

    • @user-ey7bb5ol8c

      Quantum computers work with probabilities. and they also aren't 100% precise by design due to that.

    13 For it was You who formed my inmost being; You knit me together in my mother’s womb.
    14 I will praise You, for I am fearfully and wonderfully made. Marvelous are Your works, and I know this very well.
    15 My frame was not hidden from You when I was made in secret, when I was woven together in the depths of the earth.

    Anyone else notice that he is claiming credit for the work of PhD students he was the advisor for?
    Mandal, Soumyajit in 2009, and Woo, Sung Sik in 2012 (RUclips deleted the comments that contained the links to the papers I originally posted).
    Any papers he wrote on the subject were after these two, 2014 and after. Just claiming the credit of other PhD candidates as his own. Pathetic.

    Funny that people can recognize the creator of a tooth pick, but they still try to deny GOD as the creator of Humans. When even a cell is unmeasurable, more complex than a tooth pick. THINK and be wise, as the fear of God is the beginning of wisdom. Just look at how God is in perfect Trinity just as Room (length, width, height), Time (past, present, future), Matter (Liquid, Gas, Solid) AND then our Universe which consists of Room, Time, Matter... Open your minds and accept your Creator. Recognize him and stop denying the very truth and obvious necessity of GOD.
