What is Cybernetics?

[Enysvar]

I study information science but I really want to get into cybernetics! but it doesnt exist in my country...

[vidmojo]

it's mostly used in marketing and logistics, it's a science that just steals from other sciences. pretty boring too, as all the applications for it are really just managed entities from other sciences like biology, physics, chemistry, computer engineering etc..

[KiloSierraAlpha]

Great vid! Thank you!

[globalbeehive]

@Javierlivas: @4:50 the video says: "Cybernetics must thus be defined as 'the study of systems that are open to energy but are closed to information and control'." I don't understand, wouldn't transformation require that systems remain OPEN to all: Energy, Information, Control? If they are NOT open to Information and Control, then how is transformation caused?

Nice video, i'm trying to find a good undergraduate degree program in cybernetics, i'll soon have my degree in Biomedical equipment technology all i have to do is finish up some general ed. anyways i was wandering if you had any advice or new of a good online program because i'm limited in my ability to attend a university in person.

[TheLifePerfect]

The only kind of cybernetics anyone cares about is the kind that allows a human mind to exist in an artificial body along with intrinsic ablity to access information networks. We don't give a damn about some greek sailor.

[JAVIERLIVAS]

@TheLifePerfect Pretty fine by me. But who is "we"? Not very many I presume.

[TheLifePerfect]

@JAVIERLIVAS I'm not trying to be insulting. Language evolves over time and this usage of Cybernetics is certainly one from the past.

I doubt many people with a shred of common sense would call their accountant a computer unless they were being intentionally dense or eccentric.

[TheLifePerfect]

@JAVIERLIVAS You are more polite than I am, I generally consider such things a waste of time in the relm of science. Your daughter looks good in a bikini.

[whydid666]

@JAVIERLIVAS WE ARE BORG!!!......sorry I tried to resist but it was futile.

[TheVelerefonte]

@TheLifePerfect well yes but when the Greeks talked about astronomy,history,mathematics,­and inventions tha took place through the centuries you or at least the most of the wold didn't do anything but trying to expand and show who's the baddest.So i'm just saying that if there weren't the Chinese the Romans,Egyptian and other ancient civilizations you would probably have no idea what cybernetics is or anything!!!So have some respect!!!

[FantabulousNoise]

@TheLifePerfect Feedback is far more profound.

[Timothy7384]

Really interesting thanks i first got introduced to cybernetics throug a book from Maxwell Maltz called Psycho Cybernetics and now i am reading the book of Norbert Wiener i love it.... it makes the way the world and all systems work by communication and control so much clearer at leas for me :P so thanks again and good luck

[JAVIERLIVAS]

@Timothy7384 The continuation of Psycho-Cybernetics is my book Beyond PsyCyb. but it is in spanish. If interested contact me at javierlivas@mac.com for a free copy. Thanks for the comment. Cybernetics is the present and still is the future too.

I paused it at the 3 minute mark so I could take in all the science :)

Peace.

[subfrostedzero]

cool:)

[AllKillA]

Oh dude... Why is there no explanation of cybernetics you can understand....

[JAVIERLIVAS]

@AllKillA : Dear friend: Cybernetics is about communications and control. It is also about highly complex or dynamic systems. information is important because connections among the parts of a system make these parts behave in a certain manner. It is of course very general because it covers many things, especially those that show some kind of purpose. I do not know how to say it any simpler.

[Saighton]

@JAVIERLIVAS So, it's the science of how [complex] systems work and communicate information (and commands) between themselves? [For want of a more educated description]

[amusingisthedawn]

@AllKillA

Yes.

[bune88]

scar symmetry sent me here D:

[mentalbreaker]

the topic is good but i feel sleepy

[JAVIERLIVAS]

Well, wake up and give me some suggestions to make it more engaging. Without cybernetics, no internet. Javier Livas

[futurefter]

@JAVIERLIVAS read the text faster, don't pause between words.

ex: 3:41 -> "I heard ... SB says ... that his friend .... RA ........ was ..... an absolute ... genius."

You read it like they were separate sentences.

[ybuwho]

I don't think cybernetics is about making 'successive approximations' to obtain a 'desired outcome'. The emphasis is on the self-regulating properties of (for example) a fighter jet plane or a steam engine. Its about that process of feedback, in maintaining the functioning of that mechanism, not the desired outcome.

[jawilson810]

I'm still trying to understand cybernetics is it basically trying to come up with the best possible answer/outcome??

[JAVIERLIVAS]

Not necessarily the best, but the one you want. Cybernetics uses circular logic to make successive approximations to the desired outcome. It is not a calculation but a honing in process.

[OutaSynch]

I especially liked the nude photo at 3:00. What a way to make a dry subject more appealing. :-)

best greets from a little town in germany :-)

Nice presentation! Very clear.
