because smells aren't really real, just like taste.
it's pretty much your brain just fooling you into thinking something is there and using electrical signals to accomplish this. just think of it as sight, and how everything you're seeing is actually inverted and all in black and white
Because sound is vibrations in the air that can be easily converted to an electronic signal by electromagnetic induction, whereas smell is caused by gas-phase molecules interacting with sensory compounds in our nose. This is not directly related to a limited number of properties that can be sampled, although we are able to profile smells using mass spectral analysis with fragmentation pattern library corss-referencing
If we understood the mechanism of smell better it might be possible to create a sensor that measures "smell". So far that is not possible. Inb4 Luca Turin shills
You're implying smell is as easy as audio. Sound is just waves over the air that we can measure. Smell is tied to our biology. Chemical reactions happen in the air, and our chemosensors detect this then interpret the data.
It can, but such capability isn't nearly as useful as capturing light and sound. And it's probably harder, you've got to have some way to analyze ever single particle and combination of particles that land on the sensor. And then what are you going to do with the information? To "play back" the smells, you've got to have some way to release particles back into the air in specific combinations.
>>45595478 Fuuug, what if we culd have like a dream world, like the matrix, like where everytone has thier own personal hevean, you know man? Like Nurato, the hole madara uchiha plan with the rinnagan, where he wanted to put every person in his own pesonal dream world, but noon of the nijas approved? I think it' wouldnt be so bad, so I actually kind of argee with him, is that so wrong?
>>45597685 This is the only sensible post in this thread.
Smell and taste are triggered by chemicals, whereas sight and sound are triggered by vibrations. It isn't impossible, but good luck inventing a consumer device that can splice together molecules on-demand
But we can't actually capture sound. We can only approximate it. Zoom in on any digital waveform using something like Audacity and you'll see how fucking blocky it is. Digital audio is a farce. Tape and vinyl has a superior resolution and is something closer to "real sound" but even then you have to contend with the imperfections of the physical media.
pretty much everything with human experiences devolves into understanding the nature of consciousness, which is an unsolved problem. Science can help us figure out the cause and effect of behavior that leads to phenomenons such as "hearing" and "sight", but our understanding of smell is not as well understood. The mechanism that allows our noses to so uniquely identify a particle and translate that into a "smell" is mostly hypothetical.
The most retarded thing i could think whit half don pedro ron bottle.
What would be the odds to make a little machine powered by a PCIe-Slot that contained chemicals that if mixed could reproduce different smells? That had 2 tubes that go connected from the computer to your nose and your mouth.
The only thing i can think of this fucking up are 3 things.
1. That the chemicals container gets damaged and spreads around the motherboard and fucks it up. 2.That a error happens and you end smelling shit. 3.That this sounds impossible.
Soon we could reproduce everything whit it.
Whit OR (RIP) a good headset and whit this you wouldn't need to go outside anymore.
Sound and light are waves, they can be created and emitted easily with modern technology. Smell is your body detecting substances, actual molecules, so unless we find a way to fool your brain into thinking there is a substance present, you need the actual substance to trigger the smell.
>>45598392 Photons behave as both particles and waves, it's better to visualize them as rays. Light intensity only exists in our minds - the more frequently a photon strikes your retina, the brighter the light. Color also only exists in our minds - the three types of cones that exist on the retina each react only to photons whose wavelength sits within a certain range.
Smell is caused by chemicals binding to olfactory receptors, which in turn may trigger a neural response in the olfactory bulb. The reason smell is so vibrant is because some of those chemicals inevitably end up in your nasal tract, which connects to your pharynx, and climb up and bind on receptors on your tongue, which work the same way, giving you the sensation of tasting smells. None of this information is "hypothetical".
I've often wondered what smell-based media would be like. If I'm not mistaken, smell is one of our most acute senses, so I reckon if we ever managed to create something akin to music with smells, it would be really incredible.
>>45601086 Every sense that human beings have is completely subjective and relational. I can only assume that your blue is the same as my blue, and that if you gave me the fragrance of a rose, I could tell you it was the fragrance of a rose. The actual smell and color is conjured up in our brains, but there is no way of knowing we are experiencing anything differently.
Because you'd need incredibly advanced sensors able to detect all kinds of molecules and a huge database of fragrances to look up from. But recording is the easy part, to actually play the smells back, you'd need to synthesize the exact same molecules and emit them into the nose in real time, and we won't have such technology for a pretty long time, possibly not in our whole lifetime.
>>45597770 That's actually the way technology is pushing right now. Not for the purpose of making smellovision of course, but because there is huge demand for artificially synthesizing DNA/RNA strands and amino acid chains. In the future, you will be able to buy a box the size of a printer that can do just that, and almost any other organic molecule as well. You will also be able to buy a machine that can sequence the entire genome of thousands of organisms with the press of a button. As a biologist that likes to tinker with this stuff in my spare time as well, it's gonna be glorious.
>>45597855 If you digitize the original with high enough fidelity you can capture all the information in the medium, that goes for vinyl or tape, or any other analog media. The information content no matter if it's analog or digital will always be limited compared to the real world. Vinyl doesn't magically contain infinite amounts of information..
>>45595224 Sounds are just different frequencies. Smells are because certain chemicals touch sensors in your nose. Good luck reproducing all those chemicals. Learn something about anatomy you fucking i/g/noramuses.
>>45603373 lel Anyways, the war would have been stopped even if they didn't break the enigma machine. The US had nukes and if Germany was going to win they'd just nuke them. It's not like they have any reservations about just nuking willy nilly.
>>45595224 Sound is just a mechanical wave of pressure. Smell is triggered by different compounds. If you need to transfer the smell of shit from point A to point B, you need some shit molecules in the receiving end to recreate the smell from point A. Perhaps, if you made a device that can read the molecule structure of the shit A into a digital form and another device with different shit molecules to the B end that would receive the information and put together the same molecules to create an identical smell of shit.
The nose is a molecule detector. To recreate smells you'd have to be able to synthesise hundreds of different molecules on the fly for each smell. Or if you're planning on storing them, trillions. Such synthetic abilities are far beyond the scope of what pharmaceutical companies do when making hundreds of thousands of different compounds to test as medicines. It's far beyond cutting edge industrial chemical technology that takes billions of dollars and massive complexes to do. You're not going to fit it in a box on your desk.
You're not going to get smellovision until we get matter replication- until digital signals, with application of energy, can be converted into the matter of your choosing.
>>45604945 Smell isn't even atoms, it's molecules. If it was just atoms it'd be easy to do.
Smell technically can be captured, but it's analysed by chromatography and mass spectrometers. You can detect smells but they require gear that's the size of a desk.
>>45606196 Let's not get into the nuke japan debate, but you didn't have to nuke japan. You could have just firebombed hiroshima and nagasaki and killed 100,000 people instead of 150,000.
Or just not bombed japan at all, and sat around on your thumbs waiting for the japanese to give up out of your good will.
Japan's cities were being firebombed to shit, killing hundreds of thousands, before the firebombs. In europe, they were dropping bombs with 6-14 hour fuses, mixed in with the regular bombs. The survivors could not be rescued because more bombs would go off. In dresden, hamburg, and other parts of germany, massive firestorms were produced with conventional bombing, killing hundreds of thousands.
The nukes were just doing the same as regular bombing, but instead of requiring a fleet, it just required on plane.
Saying it was neccessary or not is a matter of hindsight, but the american servicemen on the fleet's radar ships that were the number 1 target for kamikaze attacks definitely owe their lives to a shortening of the war with nukes. Conventional bombs were supposed to shorten the war, too. Didn't do shit. And killed way more people than nukes.
>>45600130 That kind of understanding is insufficient for the kind of simulation required as we do with light and sound. How does our brain code for the various particles that are dissolved (which is tens of thousands, upwards of one million unique smells)? What mechanism is "detecting" the particular makeup of the dissolved particle? To say that olfaction is "well understood" is an overstatement. We're still limited to generating smells from things that we already know have a smell.
>>45595224 Because sound is vibrations. That's not too hard to reproduce. Things like smell and taste are actual very small interactions between certain specific molecules and you. It's not easy to recreate a bunch of different molecules depending on what smell you want.
>>45604945 People are saying his post is retarded because it is, the fact that our brain is interpreting our senses is completely irrelevant to the question. Furthermore he says a couple things that are just obivously wrong, hence the bait comments
>>45606207 It wouldn't be much easier if it were atoms as you're smell-o-speakers would still need element resevoirs
It can. If you actually did basic fuckin' chemistry, you'd know that reactions between mineral acids (shit like hydrochloric and sulphuric demon pisswater) and organic acids (shit with loads of oxygen, carbon and hydrogen in it like lactic and citric angel diarrhoea) creates gassy crap called esters. Like how light creates images in your eyes, these gassy liquids produce smells when their emissions go in front end of your oxygen circuits. This is how perfume is often made, but that means it's fag shit and these basics are all I know about it.
>>45610675 To elaborate on the creation of smells that come from raspberries n shit, all you need to know is what the plant needs to survive. Minus that from what you put into it, and then fit the ions you got left into some compound that look vaguely similar to things that belong to the required acid groups. This is like trying to work out what image you're projecting from how many volts are in the power current though, so trial and error is an obvious step in development. To synthesise all known smells and leave room for the ones we don't, you'd need all ions used in acids and the conditions to make em do shit - you'd also need a way to control the "amplitude" so you don't hurt your nose hairs
>>45610772 Hi anon, This is a tech board, no smell cannot be captured. The most advanced sensors currently deployed ate gps, humidity, ambient photosensitive sensors, accelerometers, microphones. Answer why? Sound is produced by forced
