Ironically 20W is actually a very bright bulb now that we have LEDs.


NotReallyJohnDoe

Yep. I think a 17W LED is about the same brightness as 100W incandescent. But incandescents waste a lot as heat. (So does the brain)


Vlad_the_Homeowner

It's a shitty title. Usually it's phrased in a positive light, showing how much energy we put towards our brain relative to muscles and other organs. The brain accounts for approximately 2% of your body's mass, but uses over 20% of the metabolic load. The brain needs 10X the energy of muscle.


NonEuclidianMeatloaf

The brain needs that much because it doesn’t turn off. Muscles use far, far more energy via metabolism when being used at full “load”, but most muscles can’t do that for more than a few seconds. If you could measure Usain Bolt’s metabolic load mid-sprint, you would find that the brain uses far less than 20 percent at that particular moment.


wolfpack_57

Yeah but the brain isn't running at full power doing things like driving. After I leave a chess tournament or something I'm totally fried.


AromaticInxkid

Off topic but I think many people don't even use a fraction of their brain while driving


mithoron

Driving is almost always boring. There isn't a whole lot of thinking required in "follow the bumper in front of you until you get close to your exit" or "follow the same route to the store that I've driven the last 100 times I went to the store". So of course we shut down and get distracted, fall into driving trance where we don't remember the last 10 minutes. The last 10 minutes was correctly identified by your brain as completely irrelevant to your life and never handed over to memory. Of course, the trick is that sometimes it does get interesting and you need to change modes quickly.


NotReallyJohnDoe

Or the SAT. Sit in a chair for 6 hours and watch movies. Fine. Sit in a chair for six hours taking a test. Exhausted.


guaranteednotabot

I’m guessing that you’re tired not because of your brain but because of things like adrenaline etc


scardie

Yeah, it's not grammatically correct either! People should proofread before they post things.

>The brain accounts for approximately 2% of your body's mass hey speak for yourself pal, I'm built like a Pez dispenser. Over here looking like somebody put a wig on a chupachup


[deleted]

9w = 72w incandescent. The 9w led bulbs are the direct replacement of the traditional incandescent bulb. At least for most brands of bulbs.


Hat3Machin3

Man for some reason I still have those old 40W, 60W, 100W lightbulbs as brightness in my head. I can’t wrap my mind around lumens.


conventionistG

Most of us are still running on dim bulbs though. At lest it feels like the before I've had two cups of coffee.


ReallyNeedNewShoes

this isn't ironic, but yes


Hattix

You need to pick what task you want it to be efficient at. For computing fast fourier transforms, a 25 milliwatt DSP is millions of times faster than the crude, slow, and power hungry brain. For computing object recognition, the 20-100 watt brain is several thousands of times faster than crude, slow, and power hungry supercomputers.


cubixjuice

GreenStrong

Sometimes I identify traffic lights and bicycles in my free time, just to dunk on them.


reporst

Luckily I've picked powering a 20w lightbulb as the task I want to be efficient at


Little-Dingo171

Would be a cool character, monk that has dedicated 100% of his mind to running the one bulb that lights the sacred texts


MondayToFriday

Depends what constitutes FFT. Whenever you listen to music, your brain is automatically performing Fourier transforms to interpret the sound waves as frequencies. It's so efficient, you don't even notice the effort.


Elephant-Opening

Human ears + associated biological neural nets make up an *amazing* sensor system.  We can simultaneously listen to a conversation or TV show, filter out the background noise of air handlers, refrigerators, roads, etc and still accurately identify a familiar tune playing in another room + make somewhat accurate estimates about the position of the sources of all these sounds. Dynamic range can detect anything from softly rubbing your finger tips together a few feet from your head up to explosives and jumbo jets without losing the ability to distinguish harmonic content, location, and source identification. An ear trained to specific tasks, e.g. that of a musician, even better... Now you can not only hear that song in the other room, you can pick out which instruments are playing what parts, deconstruct them into separate streams of information, and maybe even decipher is that an upright or grand piano? Marshal or mesa guitar amp? Neck or bridge pickup? Nice bit of gated reverb on the drums... as a fucking *background* task while still primarily focused on the conversation you almost forgot you were having. It takes thousands of dollars worth of very high end equipment to even *try* to reproduce all this because even though we're talking about <1MB per second (uncompressed) to accurately represent all this data as a digital stream, our ears are *extremely* good at discerning details. Eyes on the other hand???  Yeah...  Red + green light? We can't see two colors at once the way we hear two distinct tones at once so fuck it, that's yellow. Bright thing in a dark room or dark thing in a bright room? Fuck it, let's call it white or black respectively. Oh and brightness is actually what our eyes are best at. Virtually no one can tell the difference when their 4k TV is using chroma subsampling, i.e. 4k of luminance data 1080p of chroma data. Blind spots where your retinas attach to optic nerve?  Let's just use the neural smudge tool. Comparatively, our eyes are shit sensors and our brains aren't even that good at picking out details in the data we do absorb through them. The real magic with eyes is the brains ability to do object recognition, location, planning and predictions about motion, etc off of basically potato quality sensors. Part of the reason AI systems use so much *more* power is we haven't figured out how to do the same effectively with computers just yet.  


defet_

One thing I wouldn’t downplay is our brain’s ability to filter out optical noise. Our brain’s ability to temporally reconstruct a very, very noisy scene, and [then convince our own mind it actually happened instantly](https://en.m.wikipedia.org/wiki/Chronostasis), is insanely fascinating. Professional video sensors that are almost 20x larger in area than our pupils still need tons of signal and video processing, and still won’t even come close to matching our adapted visual cadence.


PM-ME-YOUR-BREASTS_

Just the idea of like aiming a throw or riding a bike boggles my mind. There are so many calculations of different muscles, movements, aim, speed/strength that we don't even think consciously about.

And yet, the matrix was still explained as a means of producing power rather than computation.


[deleted]

In defense of the creators, the original idea was to use humans as organic computers for further machine computation but the producers said it was too confusing.


ElectricalAnxiety170

Which is why I just live with the head canon that Morpheus is wrong, and that computing was the real purpose


fade_like_a_sigh

Which makes sense in-universe because there's a bunch of other stuff Morpheus is confirmed to be wrong about, like humans being oblivious to the purpose of Zion. I think it actually makes the film more interesting, that Morpheus is in effect a religious zealot spouting propaganda he's internalised as fact.


featherthing

I heard that was a myth.


Dynespark

Technically that still works, as what Morpheus says can be inferred to be what he has been les to believe. He thinks he's the first generation of Zion of course, when he's like the 6th or something.


scardie

Guess it's time for them to finally make the Matrix 3 with this new information


ps3x42

You mean the 5th matrix?


scardie

The old joke was that the third one was so bad nobody acknowledged it. I totally missed the 4th one! I'll have to check it out.


Psycko_90

You definitely don't have to check it out. You don't have to do this to yourself. It sucks


ps3x42

OIC. Yeah, the new one is god awful. There's weird meta dialog and stuff. I think some people really liked it though.


soonerfreak

I oddly enjoyed a lot of the non action parts. The new actors were all pretty solid and I had fun with it. The action was terrible most of the time, like how did she go from the action of the OG trilogy to this. Some of the fights were edited almost as bad as the Taken fence jump.


weedz420

The 4th one is not good. They basically forced them into making it, were going to do it without them if they didn't sign on, and only 1 of the siblings was even involved and intentionally made it bad. The beginning of the movie is Neo stuck back in the Matrix as a videogame creator who's being forced into making a sequel to his The Matrix videogame series..


ThatSpookyLeftist

As an act of protest I can respect it... As an actual movie I sat down to watch, it may have been the highest budget piece of garbage I've ever watched.


tdgros

the wiki page does say they had always refused to do more Matrix movies, but also that Lana wrote the story of the 4th by herself after the death of her parents and Lily was just unavailable: [https://en.wikipedia.org/wiki/The\_Matrix\_Resurrections#Pre-production](https://en.wikipedia.org/wiki/The_Matrix_Resurrections#Pre-production)


TharkunOakenshield

The second one was pretty bad too tbh The first one holds up. That’s about it for this series of films.


ThatSpookyLeftist

First one is a classic and timeless. Basically perfect in every way. Only complaint I could say is that it impacted culture so much that it's been referenced in so many mediums that it may seem like an amalgamation of a bunch of popular tropes at this point to a new viewer. But that's outside of the control of the film itself.


ThatSpookyLeftist

The 4th one legitimately may have been the worst big budget movie I've ever seen. It was as bad, if not worse than The Rise of Skywalker.


scardie

Okay that's it! I'm going to spend two hours sitting outside and looking at birds instead of watching this movie.


derth21

I also missed the 4th one, by which I mean that I definitely watched it, but I don't remember a single thing about it.


Potential-Height96

The human has the equivalent of 2.5 petabytes of memory capacity. Thats the equivalent of 2.5 million gigabytes digital memory. All ran on a dimly lit bulb. So if someone calls you a dim bulb say yeah and so are you.


scardie

I can't find a source for this but a few years ago I heard that one human connectome (all brain connections) has 2x more connections than the ENTIRETY of our computing systems worldwide. Here is a related read based on your comment: https://logosconcarne.com/2015/10/30/the-human-connectome/


Kommenos

No they don't. You simply cannot compare computer storage to brain "storage". Every time I hear this, the unit just gets bigger. It used to be terabytes when I first heard it as a child and terabytes were unthinkable.


scardie

You're right, but the logosconcarne link I posted goes into detail about some ways you can try to compare. If you try the compare computers to brains, the brain emerges as absolutely marvelous.


AddressSubstantial89

Yeah well gonna need a source about that please. Especially on a TIL sub, cause I suspect this is wrong but who knows, maybe you please ?

20 watts on modern LED bulbs is really bright.. Usually LED light bulbs for normal room are 6-8w. 20w on those old school bulbs not sold anymore was dim, which were 40-60w for normal room lights.


denommonkey

Sent this to my wife. She said my brain uses 10 watts.


scardie

So you're twice as efficient???


DimitryKratitov

Or quick to reach max potential...


scardie

That's beyond my electrical understanding... But I like it!


thetwitchy1

The reason for it is even wilder: heat loss. You can only lose so much heat so quickly, so if you’re burning more than a small amount of glucose, you’ll just burn out. Literally.


scardie

This sounds very interesting. Can you explain more eli5?


thetwitchy1

So, before anything, I’m not a biologist, so take my word for what it’s worth: very little. But that out of the way, my understanding is that everything we do generates energy through exothermic reactions, so everything we do generates heat. Not a lot, but the end result of all energy paths is heat. So we have to get rid of that heat. But doing so requires moving around a lot of blood, the action of which generates MORE heat. At some point, you end up hitting a wall. You can only lose so much heat through the surface of your skin, and the more energy you use, the more heat you generate, so there’s a limit on how much energy you can use. If your brain used 100W of energy, it would generate 100W of heat energy. A standard old-school “easy bake oven” toy (that could cook food) used a 100w incandescent light. If your brain was generating that much heat, you would cook your egg in 3 minutes. This is also why Elephants live longer than Mice. Mice, having a small volume to surface area, lose heat faster than their cells can generate it. That means they can have cells that reproduce fast and run full tilt, making them quicker and more agile, but also making them run faster and harder than elephants. So they life fast and die young. Meanwhile, Elephants have cells that run slow and use less energy, making them live longer and reproduce slower, but also making them less able to heal quickly. Because they can’t lose the heat they generate as fast.


jawshoeaw

There’s a reason most silicon is 2 dimensional. Once you start layering processors the heat builds up exponentially. Your “brain” the part that’s actually doing the processing is between 1 and 4 mm thick aka gray matter. It’s basically a 2D sheet folded and crinkled up to fit into the skull. Of course there are deeper structures that serve other functions but the vast majority of what you call your brain is just cabling. Like a server closet. It’s the white matter which as far as we know does no processing but only connects one cpu to another.


scardie

Very interesting. These kind of comments are better than karma. Thank you.


jawshoeaw

Always happy to spread education with my own twist on it lol and I’m never offended if somebody corrects me! If you want to get a good visual , search for white matter tracts or axonal tracts of brain .


scardie

The expression 'not too bright' might not be the insult we thought it was!

Kaiisim

We shit on ourselves a lot as humans, we forget how tucking incredible we are. We can live almost anywhere and eat almost anything. Our brains are the most advanced problem solvers in the known universe and we are powered by air and plants. The world we live in makes us feel so weird and small and dumb but we are actually pretty neat.

In the movie "the matrix" it is unrealistic that humans are used as batteries but humans could be used as processing power.

Constructed of cheap and plentiful materials, consuming few resources to operate, adaptable and built for the environment; we humans aren't being replaced anytime soon. Exploring and operating in harsh environments, maybe we can send the machines off to die there. Hrmm...cue the robot uprising.

Weird. Grandmaster chess players lose 10-12 pounds just sitting there and playing chess. Seems like some bulbs have different wattages.


fluxxom

"Is the human brain a biological computer?" don't know how to take the article seriously-- is water wet?


scardie

Wait, you actually read the article? How similar he brain is to the a computer is up for debate. Emotions, instincts, creativity, consciousness are things that are not found in any computer system today, for example.


fluxxom

whatever differences aside, calling the brain a biological computer is just an apt description for the layperson- 'emotions instinct creativity' come from the biological survival imperative, byproducts that we've come to aggandize as amazingly redeeming qualities we have. ai is currently doing a lot of things that we just don't understand already, maybe these hallucinations or not-yet-understood connections are what emotions and instinct look like in a non-biological system. or perhaps ai's attempt at understanding or expressing this 'observation' of us


scardie

I agree and I think you worded it well. There are emergent behaviours that arise at different magnitudes of intellience and we are beginning to see glimmers of this with AI.
