From A Kick To A Bang - Putting Together The Big Brain Theory

[rainxxxx]

daft cow!

[drche420]

Occam's razor destroys the Big Brain Theory. Its an extra unnecessary assumption.

[dabomb1357]

@drche420 What? No it's not. A theory on the very beginning is absolutely necessary because it happened. If anything is an unnecessary it's the idea that we need an all pwoerful sentient being to start things off.

[drche420]

@dabomb1357

This universe had a beginning, but how do you know this was the first universe? Since there is no method of verifying whether the big bang was the first or only one, it is an unnecessary and unwarranted assumption to posit a sentient being to "start things off". Secondly, intelligence only arises late in the evolutionary process. It cannot exist before the simple life chronologically.

[dabomb1357]

@drche420 It doesn't matter if it wasn't the first big bang, our universe still had a beginning and so that beginning needs a theory. The second part agrees with me. Did you read my comment?

[drche420]

@dabomb1357

My point sails over your head... Occam's Razor is a rule of thumb that says the explanation with the fewest number of assumptions is the best. Since the natural explanation of the universe does not posit a sentient being, the natural explanation is the most likely. i.e. There is no reason (evidence) to suggest a sentient being was necessary (or exists).

[dabomb1357]

@drche420 No, you're point is wrong because you don't understand occams razor. It's not the fewest assumptions, it's the simplest. If something happens, you need a theory to explain why, ignoring it is moronic an not the point of occams razor. As for the second part, once again, YOU'RE AGREEING WITH ME. I'm the one who said occams razor defeats the idea of a god in the first place, not you. Read the first damn comment.

[drche420]

@dabomb1357

I'm afraid you're flat out wrong. Occam's Razor deems an idea more likely with the fewest assumptions. Even if it was the simplest, how is an origin-less sentient being a simpler answer? Its not. You're ridiculous.

[dabomb1357]

@drche420 What? You didn't suggest fewer assumptions, you suggested no assumptions at all, you suggested no idea whatsoever. Are you fucking kidding me, have you read anything I have written, at all? I said any sentient being with defeated by occams razor. YOU ARE AGREEING WITH ME. Are you a troll or just a complete moron?

[drche420]

@dabomb1357

You obviously aren't paying attention. What you would call "my suggestion" was the natural explanation of the universe, i.e. no god needed. Sounds like you're incredibly slow or you're trolling me...

[dabomb1357]

@drche420 Given that you cant have possiblly missed, no matter how stupid you are, that it was me who said there was no god needed, I'll just assume you're a troll.

[Starbat88]

I thought the "Big Brain Theory" was a radical new theory of cosmology. How is any of this about the big brain theory?

[zorandesign]

Is it Epilepsy or it's just me not being able to understand why smart covered girl are much sexier to me than those stupid naked ones?

[zorandesign]

Great speaker, presenter. I enjoyed the explaining even though I have very little knowledge in medicine. The example was very good and she did a great presentation.:)

[sammeo]

[sinasfles]

Einsteins brain could have srinkt (gotten smaller( dont know how to spel it)). Happens after death

[TheEennaamvooryoutub]

funny the link with football :)

[celia65os]

Profética, é a piranha que te pariu. Nação de exibidos. Toma-lhe, marginais. Todo aquele que invade a minha privacidade, que deturpa a minha vida ou propaga a calúnia, tenha na carne e no sangue o mal de volta. Que seja em sua casa e perca três vezes o que ganharam enquanto fazem a mim e a meus filhos de bonecos/robôs com hipnose e chips por décadas. Neuro-programação em vítimas, punidas com agressões e curras.

[celia65os]

Quem dá audiência é cúmplice, é marginal. Há de pagar. Que seja na carne dos seus. Usa o cú da puta que te pariu. Meu dinheiro é sempre digno. Faz filme porno com sua mãe hipnotizada. Aqui a polícia/política/jurídico são vendidos. O poder quer um bode expiatório p/ controlar o povo pela ignorância, assim como vcs, burros.

[jumb0mumb0]

9:98 Speaker explains a devastating chronic illness (Alzheimers) and while illustrating that some of the nerve cells in the brain (the team) are dead the audience chuckles. So insulting that the speaker responds "it's sad I know" in a sarcastic tone.

[jumb0mumb0]

Fucking hooligans in the audience don't know when to shut up.

[CodePython]

"if your italian you cry alot" lmao

[CommissarBraxton]

6:45 I guess one of them there fifa games might to better.

[g0d0fw4r]

great stuff!

[jabasong]

Thanks Sarah - you make science so interesting and communicate that excitement!!!

[BBMix]

Great lecture, but the audience sounds like canned laughter.

[see4ward]

If Sarah isn't taken, I'd love to intro her to my brother...they'd be perfect for each other ~ smart, funny ~ and explains complicated scientific things in ways that I (and other non-scientifics) can understand. Would have loved to have seen her lecture live. As much as I enjoy watching (listening and learning from) my brother explain biochemistry and genetics.... Just sayin' ~ Incredible, awesome lecture. Thank you for such a wonderful post!!

[broodyart]

The cells[memory] & the amount of "tendrels" is a good indicator of where they belong in the process of thought. One for each of our senses, feeling, others for connection to other cells. I know from damage I recieved in an auto accident, that a tendrel can be severed or damaged. & to extract info. from that cell, another "sense" i.d. tendrel must be used to bring out the word that's gone.Instead of "pheasant", pheasant feather had to be thought of, & leave out feather. It worked. Study damage!

[zorandesign]

they noticed that there are more connections, but they couldn't say that it is important because they actually lack those connections :D

[blshtry1]

grammar to be popular like tv and music is

[spinynorman1982]

This is great, but the audience sounds like the perfect group for a taping for Full House.

[Teghead]

She is a very entertaining lecturer but I did not learn anything new about comp. neuroscience from this.

She would be a great children's pop science lecturer.

[dabomb1357]

@Teghead pop sci was the entire point of this, she wasn't teaching grad students here.

[Teghead]

@dabomb1357

Sure, but pop sci can be more challenging than it often is; people are scared or aren't sure how to convey some detail in an accessible way.

I just felt that invoking computational neuroscience created certain expectations.

For school-kid pop sci she is a very good speaker!

[hellobal100]

she is brilliant

[HaNoCr]

She basically explains how neural networks, simulated by a computer can explain things you observe in reality, but cant measure. The method she explains is an Error Back Propagation Network model. She did quite a good job and had chosen a very good example. The EBPN often used in combination with AI mechanisms like mutation, as well as evolution models. THUMBS UP FOR HER AS A SPEAKER TOO!

[opaldragon75]

That was awesome! She is a skilled speaker... sadly we need more people like her so the rest of us can grasp what is going on!

[supermastergod]

I used to be into science, then I took a hypothesis to the knee...

[FreeeeS]

@supermastergod *an

[BiggerThinking1]

a species that pays footballers $10 million a year and scientists $50,ooo a year deserved extinction!

[opaldragon75]

@BiggerThinking1 sadly, I agree!

[ImperialUSA]

@BiggerThinking1 Surely you don't actually think that?

[2darbit]

@BiggerThinking1 -- there needs to be a fair balance. but I agree, somewhat.

[BiggerThinking1]

@2darbit Fair balance would be:

Scientists - $1 million a year - pro football players - $50,ooo a year - rather than:

scientist $50,ooo pa, footballer $10 million pa.!

[nickharvey7]

The flow of Time as a process of continuous change and our consciousness as a stream of unbroken ever-changing flow of ideas, feelings, perceptions and emotions are interlinked.

We all look out at our Universe from the centre of our own reference frame. Through an inverse sphere 4π of probability ∆×∆p×≥h/4π that forms the opportunity and uncertainty of everyday life. Check out Quantum Atom Theory!

[MetalCanyon]

The video was very interesting and, dare I say, entertaining (as all general populace science videos should be). Why does this have so few views?

It is so difficult to comprehend my fellow humans who devote their time to religion, wars and petty politics when, in fact, we, as a human race, should be devoting ourselves to the advancement of technology and well-being of us all.

I know I'm thinking of utopia but there is no doubt without science we'll simply end up in a dead end.

[Kignak25]

This reminds me of a TED Talk. I like it.

[lookwhoneedsahobbie]

That was an amazing lecture. I'm so glad that she knows how to speak as well. So many times have I shot off an extremely interesting speech because the speaker couldn't perform.

[DigitizedSelf]

Wow, I totally get football now! Didn't know they had to have needles in their brains though :-/

[Shketri]

;p

[Shketri]

nice presentation but the title doesnt rly suit well

[DKChatha]

she made it interesting

[DoctorPlausible]

"Try to be precise and you're bound to be metaphorical." J.Middleton-Murry

Great lecture.

[dbsz]

A brilliant lecture! Full of new knowledge and entertaining to the last second. I have to say I got surprised when the video finished and I had been watching for 13 minutes, well done :)

[ShalloeThought]

Can you have Science lectures in German too ? I suppose that would just be a waste of time though.

[WissenXXL]

@ShalloeThought: There are tons of Science Slam videos in German on our channel, and also on "WissensMagazin" and "WeltDerWissenschaft".

[blejacore]

Great

[Eminemno1fan]

Very interesting!

[computerjero]

9:27 gnome desktop ?

[Watchdawg]

Just too bad that science breeds snobs.

[sn1pe352]

Incredible lecture and teacher, after watching several UC Berkeley lectures i can confidently say this woman is far superior at teaching compared to any professor at that university

great information and conceptual analogies, LOVE IT

[QuantumGh0st]

Great analogy.

[deshaebeasley]

now do the REAL football! lol

[narekarmenian]

apparently the crowd is on real coke.

[VolcanicPenguin]

I'd prefer this without the soccer analogy.

[GetMeThere1]

I have to say: The metaphor became SO THICK that I mostly lost the thread of what she was trying to communicate.

[bv90andy]

Grat video

[superfunny1972]

thanks for sharing!

[naybobdenod]

Excellent talk.

I`ve always been an advocate of making learning fun and this lady has just proved that.

[MathLector]

he is soo hot!

[slLLyhumans]

Great video .

[Vire70]

Pretty entertaining. Good speaker. 

[defect530]

i have been subscribed to TED long enough to know this stuffs.

[JayJayAbels]

This was a well done presentation. Only quip I have is that she could've gotten to the "point" just a bit quicker. You can tell that she was nervous... but she held her own!

Good job girlie!

[arlpainbringer]

Very entertaining but far too simplistic imho

[dewinthemorning]

Science is more interesting than philosophy, at least it gives you more knowledge about our world and about ourselfs, and, as it is shown here, neuroscience tells us how our brain works.

Those scientists work very hard, and they should be more appreciated!

[mdjmagic]

@dewinthemorning Philosophy and Science are not opposites, they are two sides of the same coin. Good Philosophy is as important as good Science in that it can point out unseen problems and can construct theories that can help us understanding the meaning of, among other things, scientific theories.

Furthermore, the instances in which good philosophy has fostered new groundbreaking scientific research are countless.

[dewinthemorning]

@mdjmagic You are absolutely right! I love the natural philosophy in Jacque Monod's "Chance and Necessity", Steven Weinberg's... Karl Popper is of course a good example.

I wrote this comment because I just made a video about the philosophy of William Lane Craig.

[PeruvianCactus]

@mdjmagic The advances in science have rrendered philosophy to basically the understanding and interpretation of the human language. I heard that from somewhere but it makes sense

[Baldmother]

@dewinthemorning Agreed. But philosophy gives us science itself. Also all the other things in life that science cant and wont ever be able to study such as morality, ethics, language and other abstract ideas that then in turn help guide science.

[niriop]

@dewinthemorning "Science is more interesting than philosophy" I disagree. People tell me I should have gone into physics or neuroscience or psychiatry, but I feel that philosophy with its project of touching that which the empirical can only speculate on or perhaps never even be able to touch is far more interesting. I agree with Heidegger: philosophy's duty is to go beyond science, not be some under-labourer for it (Not to say this work isn't brilliant; I've faved this video).

[dewinthemorning]

@niriop Lately I have been irritated by WL Craig's attempt to use philosophy to justify a belief in the supernatural, my latest video is about that, and I explain some of the things that are wrong (incorrect) in his philosophy. Otherwise I love philosophy and have read a lot. Many scientists do natural philosophy in their books, which, together with the science they write about, is splendid - Jacque Monod in "Chance and Necessity" is an example, so is Hawking in "The Grand Design".

[niriop]

@dewinthemorning Craig is a lot like the "racialist" scientist Phillipe J. Rushton--they work under the guise of their respective disciplines as a cover for an ideological and social agenda. Of course this does not affect the standing of these disciplines--they just need to be flushed out by better philosophy and better science. mdjmagic makes the best point: philosophy and science are not opposed; they are joint partners in the human search for greater knowledge.

[niriop]

@dewinthemorning Natural philosophy is great, but when dealing with language, concepts, meaning, epistemology, aesthetics, metaethics, logic, mathematical foundations, and the scientific method itself, only "theoretical" philosophy can really deal with them and validate them; empirical research may help with them (Lakoff on embodied cognition, Churchland on neuroethics, Ramachandran on art etc), but ultimately, these processes and the outcome is directed by rational thought.

[dewinthemorning]

@niriop I agree with you (very good comments :)) I used to read a lot of philosophy but now, science is more interesting to me. mdjmagic does make a good point. Philosophy is nothing without science. Maybe it helps science but the profit lies the other way, philosophy needs science.

[niriop]

@dewinthemorning Philosophy effectively "created" science and its method; science owes its life blood to it. But at this point they are mutually dependent, and that is the best possible situation; I'm so sick of a supposed war between them...we need both as a means to intellectual progress, and for me both are as equally important; when idiots say we can have science without philosophy, they are literally saying we can have knowledge without a love of wisdom (and vice versa).

[Rel7eGaDe]

@niriop the problem is that the things discussed in science is now too complex for a philosopher to understand " quantum mechanic " for an example.. i agree without philosophy science wouldnt be, but there is just not much space for philosophers anymore..

[niriop]

@dewinthemorning Just to add, I am a sub of yours, and I do enjoy your vids :)

[KaylinJH]

@dewinthemorning they are two different questions though. science asks how, and philosophy asks why. Both questions are equally important.

[dewinthemorning]

@KaylinJH Yes, but many times the 'why' question is meaningless in the context it is given - for ex. "Why does the universe exist?"

[KaylinJH]

@dewinthemorning touché but i still feel its like comparing apples and oranges some times *tips his hat*

[cinereyes]

@dewinthemorning to my opinion philosophy is more interesting than science,but i think there's a different word to what you mean

[ironis24]

It is really boring, really simplistic explanation. Really good though for not experienced audience(where did this lecture take place?)

[silvercoin1111]

its good to see such crowd...science need to be popular like music or movies are

[budoracle]

@silvercoin1111 They're Germans.... does that explain it for you?

[computerjero]

@silvercoin1111 not just like… even more popular !

[TheBrradsullivan]

@silvercoin1111 boy would that be a wonderful world...i just dont have that much faith in humanity anymore

[edugio]

@silvercoin1111 Popular Science is the problem is that to understand it to be studied

[FreeformTao]

Very cool. Thank you for sharing this presentation.

[Natketty]

Great explanation! Love it.
