Analog Supercomputers: From Quantum Atom to Living Body | Rahul Sarpeshkar | TEDxDartmouth

[@majorlaser4801]

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.

[@Muck-qy2oo]

Eventhough analog computers usually work with analog electronics this isn't the main criterion for analog computation. Analog computers are analog because they build an analogy of the underlying mathematical equations. Digital differential analyzers for example work with digital electronics, counting with a clock and having digital computing elements, but are configurated like an analog computer and therefor work more like an analog computer. But they are less energy efficient.

[@TheTraveler98]

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

[@collicou]

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 ;)

[@lepmuhangpa]

Analog and digital sortof!

[@wiegraf9009]

Only Von Neumann's brain was skilled at high accuracy ones!

True that! And multiple different disciplines

Fascinating and inspiring talk. Thank you very much.

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

[@МалкопийТролян]

Well, KZbin's algorithm is digital - self-preservation, perhaps. :D

I just saw Steve Mould's water computer and decided to search for 'analog computers'. This talk was amazing, what great a speaker!

[@balapillai]

Super opportunity for the few then!

[@balapillai]

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)

[@keithvanantwerp3198]

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.

[@thememeoverlord.1949]

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.

Quantum computers could beat human brain.

@ Go!

[@factsheet4930]

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!

[@Николай-ь5ю7е]

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

[@JustinBenjaminOnline]

While I'm not convinced, he certainly makes the most compelling case for a priori knowledge that I've seen.

[@alo1236546]

A supercomputer to simulate human body should be smaller than human body. I hope someday it could be portable in my brain

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 (KZbin 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.

[@stacymaimoon4189]

he reminds me Carl Sagan...

[@AruniusMaximus]

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.
