"If you see a quark, you know you've gone too far." - great line!
Then watching Deep Space Nine is going too far?
22:30 Yes, light can cause air molecules to make sounds. You hear this with very powerful lasers such as the ones being used on some naval ships to combat missiles.
A hot enough laser will heat up the air molecules in its beam to the point that the molecular bonds break. So if you fire a powerful laser through some CO2 for example, the carbon and oxygen are separated and blast out of the way at supersonic speeds.
All of these air molecules moving so fast create a sonic boom, which sounds like a very loud popping sound, similar to a gunshot but without as much echo.
Agreed, at the University I studied at, they had lasers which would fire for either nano or pico seconds.. But the laser itself would cause a sound as if it were ripping the air apart in front of it.
And that's after isolating the sound of the electronic components first
Also. The blast from a nuclear device and the ensuing fireball is caused by the extreme emissions of x-rays and gamma rays that are absorbed by atmosphere.
Lighting on the other hand is a powerful flow of charged particles through atmosphere and not light based. Light is produced by the created plasma due to the particle flow and the creation of plasma makes the sound.
PS: Best light to use to affect the atmosphere is x-ray. Gets absorbed the fastest.
doesn't powerful lasers also create ozone, like lightining ?
@Jon H Photons do have momentum, which means they could exert a tiny bit of force on your eardrums the same way an air molecule does, just far weaker, so weak you couldn't hear it.
I'm not a physicist, but as far as I understand it, because the force from photons is so small, it causes motion on a really small scale. Motion on these tiny scales manifests as heat, meaning the pressure from a high amplitude light wave would burn your eardrums before it would push them to a large enough degree that it was audible.
So in short, photons alone can make a sound (I think), you'll just never be able to hear it.
@@danilooliveira6580 0.0 idk, that sounds cool though. I imagine that creation of ozone is just caused by extreme heat, so you're probably right. Even if that isn't the reason, though, there's a thing called a laser induced plasma channel which is where a laser ionizes atoms to create lightning, but in a straight laser beam rather than a weird jagged bolt, so lasers can definitely do the same as lightning somehow.
17:56 There exists a spider in Madagaskar, wich can shoot their webs across a river. It is called the Darwin's bark spider. It utilises some rather nice mechanics to build its unique web.
I believe it is also the strongest web and can easily catch birds. Most of the work is done by the wind though. She just has to make sure it doesn't spread to far and thin.
czcams.com/video/nlRkwuAcUd4/video.html
Yes but it flows on wind, slowly.
I had a spider appear in the office once, it was tiny, very very tiny, about 1-2mm. It was on my hand, and so light that I noticed it was there then I saw it.
When I blew it off my finger, in about 0,5s it just stopped midair and started climbing on it's web strand. That it stuck to the ceiling.
If we take into consideration that the ceiling is 3m high, and the spider at about 1,3 m from the ground (I was sitting).
It fired the web 1,7m up into the air.
Since the spider is 2mm in size and Tobey Maguire is 1,73m high = 17.300 mm
That would give us 8.650 x times spider size. And Tobey should be able to fire his web for: 14705 m = 14,7 km = 9,137 miles
*Real world does not scale like that, Air friction would be much higher because Tobeys web is larger, etc
But definitely plausible.
The spider probably lowered itself onto your hand from the ceiling.
"When I blew it off my finger, in about 0,5s it just stopped midair and started climbing on it's web strand."
It was on my finger first, then when I blew it off my finger, THAN it started climbing towards the ceiling.
And it wasn't floating or anything, I watched it for a bit, it was moving its legs (like spiders do when they climb), and it climbed straight up.
I even went above it (After watching him climb for a bit) with my hand and picked it up along with a strand of web, so it definitely was a web, shot to the ceiling.
(cyberpunk nerd powers activate!) In Neuromancer, the tech is called "Simstim", not Sensenet. The act of experiencing or recording someone elses senses is generally called called 'sensorium'. Sense/Net is just a tech company in the book's world. Technically correct, the best kind of correct.
Also watch the great movie Strange Days.
Syn's Arcade Yes, Strange Days is excellent.
Cyberpunk nerd powers activate😂😂😂
@Modustollens1 why you believe that?
ha! I got that Futurama reference!
dont forget the shape of a craft will have a direct effect on how the solar radiation effects your course.
This BARELY matters and with ships whose course you can correct its even less of a problem, but this and uneven heat radiation are why the voyager probes arent quite where we thought they should be. So while barely at all, light pressure could also technically be classified as drag(or thrust) I would say.
lets not forget that Keppler had to use solar wind to compensate for the loss of some of its reaction wheels. it was a fucking genius maneuver that actually managed to keep it alive more than it should have.
3:20 - AAAAAAAARRRRRRRGGGGHHH!!!!! There's a giant Mantis Shrimp space ship about to destroy the Earth!!
Clearly a Chitauri Leviathan.
Dude, it already has destroyed the earth, it clearly is more massive and therefore gravity and all kinds of things that are side thoughts mentioned off hand on this channel all the time happen.
Because science.
Unless it isn't science without showing my work. Nah, math is true without being shown, silly math class.
Why not use the Mantis Shrimp's incredible punch instead of lightning? Each of the smasher’s strikes produced small flashes of light upon impact. They are emitted because the club moves so quickly that it lowers the pressure of the water in front of it, causing it to boil. This releases small bubbles which collapse when the water pressure normalizes, unleashing tremendous amounts of energy. The cavitation, is so destructive that it can pit the stainless steel of boat propellers.
Not to mention the fact that there are two variants of Mantis Shrimp that are equally amazing predators. One with a club, and one with a spear. Evolution is awesomr
Don't forget pistol-shrimp XD
To be fair, he has already mentioned these in previous episodes. Maybe he doesn't want to keep rehashing the same stuff
@Jon H Where exactly do you think the heat is coming from, Cap Slock?
8:45 borg cubes...
34:30 i want the full healing beds that the movie Elysium has (it scans a person's dna and repairs all damage to it, putting back to perfect health)
Thanks for being an awesome science communicator and inspiration. I think you hit the balance between tmi and the laymans general idea perfectly.
Fun fact, the Vulcan nerve pinch was never supposed to be cannon. The Spock Actor invented it becaue he thought Spock would never punch his captain.
25:30 the block of metal goes splat as soon as it melts, not when the current is turned off. The force holding it up is produced by eddy currents localized at the surface of the block, that can hold the whole block up, but the liquid metal just flows around them, so it just falls.
very good show. Fun fact the mantis shrimp has 16 cells responsible for it's vision and 12 of them are responsible for color (+ UV and Infrared ) and the other for polarised light. The human eye has 3 main pigment in its cones and it can see approximately 10 million colors. And another fact , there are humans that have Tetrachromacy that have a forth fotoreceptor ( violet) cell and its estimate that they can see 100 million colors.
It's beautifully more complicated than that :-D this video gives a great rundown of the complexity of light receptors and why tetrachromacy isn't quite what we imagine it as
czcams.com/video/fDoAs0qN7lU/video.html (not sure if i didn't paste it before or what, sorry)
i know about the topic in this video..the thing i said in my comment about the tetracromats is something from the internet without my filter added. The guy in the video has a point in saying that people that are tetrachromat don't see more colors. RGB ca teoretical make 16 milion colors, so why do we se only about 10 milion?. The video doesn't explain this but has a big picture that makes you understand what do you see and what the brain lets you see. The fact is that threre is a video of a person ( female ) that was testet ( in a lab i think like the guy suggest ) to see what she sees. I'm with the guy when he says that tetrachromats don't see more colors, but they do see the world different in some ways. Doing a theoretical analysis with wavelenghts and what should they see is just that, theoretical. You would need to have cones from different animals that are mono-di-tri-terachromat and stimulate every last one of them and see how they respond because the green cone like he says won't respond the same way in every case. Simulating what people see with an effect in a camera is the worst thing to do especially when it comes to animals ( i study veterinary medicine ). It's the same with what we know about what a cat can see or what we thing that it can see. Science speculate that a cat sees worse that human in daylight and somehow better that we do in lowlight. The fact is that they see much better than we do with pinpoint accuracy especially in the dark. I belive to be the same case with the mantis shrimp ( the nature made him this way for a reason and not because like the guy says that having 12 color receptors will be a mess seeing and diferentiate colors that he gives as an exemple ). And to sum up ( sorry :)) that my comment is so long ) Tetracromat people may be an evolution or not, but we as humans don't have the best vision and again replicating what others see with an affect on a screen is just stupid ( and the accuracy may be diffrent in 100 years when we will discover that the same animals or whatever don't see as we predicted because we use different gear to analyze)
4:34 you are welcome
Thank good help.
🙏🏾🙏🏾🙏🏾🙏🏾🙏🏾
Thanks Earl
I'm wet
@@SadfoxGuyver don't forget your towel
Just wanted to stop by and let you know that you inspire people every time you make a video! I constantly look forward to new content and always learn from your videos (I take notes lol). I love the way you break down and explain things in a way that I personally can understand. Just wanted to let you know that you rock Kyle!!!!
15:40 Light can strike non-air things and get them to vibrate at ultrasonic frequencies, though it's usually not controlled enough to produce specific sounds. We call that "heat". Presumably it works the same way for air, for the little light it absorbs.
Loved the start of this video, just because I guess what he was going to do and was laughing as I imagined him trying to run to the other side as quietly as possible, dodging video equipment and people as he went.
It was great to see this live. I hope for a chance to have my questions answered here some day:). This show keeps me going.
29:00 Kyle describing braindances is what i needed in my life
Nice drawing! My son called your mantis a grashopper so that means alot! He's 2,5 years :) He also liked watching the video.(while he only knows Dutch)
Just wanted to say I love your videos. Keep up the great work!!
The reason the metal in that induction heating video drops to the bench is because it surpassed the point at which it is magnetic. Iron loses its magnetism when it heats up past a certain point.
"Be excellent to each other"
and
"Party on, dudes!"
Hey Kyle you talked about pressure points on our body you are right but you forgot one the solar plexus. If you get hit right there you can get knocked out in 1 or 2 secods ...
As a mechanic i can say we use induction heating to heat up bolts in a much safer way then torches. The tool is called the mini ducter
18:10 Up is a two letter word meaning "the opposite of down" which is only relevant within a strong gravitational field.
Well, even when you don't have air resistance, there are still some things you've to keep in mind when you develop a new vessel design, most notably the structural strength and rotation speed. If you want to rotate a very long ship for example, the stress for the structure is pretty big, so you need either a very strong structure (in other words: more mass) or a complex and more expensive thrust system to allow faster rotation speeds. This might not be important for science or transport ships, as they don't need to be rotated that often (propably just to evade asteroids and debris), but it can be a critical feature for a military ship to evade attacks and getting a better attack angle.
@Kyle, what a great show!
Question: would you still have some measure of resistance traveling through space using an Alcubierre drive? I’m thinking no, but what do you think?
If I'm right, and I'm recalling the same video Kyle was referencing, then the molten metal created by the magnetic field fell the moment it became molten metal - as the higher-energy matter of molten metal does not interact with electromagnetic fields in the same way, causing it to lose its ferromagnetic properties upon melting. So, it was dropped into the middle of the coil's magnetic current, was heated by conducting the intense magnetism, then dropped into a puddle beneath it the moment it uniformly stopped being a solid (and ferromagnetic).
Mantis shrimp cleaning it's eyes is just about the cutest thing a crustacean can do.
For the record, Electrons don't actually move all that fast. In a wire for example, they move maybe a few millimeters per minute.
I had just asked about this on the previous video. Thanks!
Induction heat treatment was my favourite part of my old job, the concept just fascinated me, and I also like to make the big pins we used to heat treat glow bright red like a lightsaber then make the mandatory "shoom woom vwoomp" sounds before quenching them and going "coshhhup". 👍 ♥
7:40 proably not nerve pinches, but just under your armpit there's a whole bunch of nerves (I've seen a lot of martial arts focus on attacking this spot)--it wouldn't techncially knock you out from all your nerves shutting down, but it hurt a lot--it depends on the individual's capacity for pain. an average person may just recoil or withdraw from that pain--kind of like a horribly bad case of funnybone injury (which basically is the same--your nerves reacting as if you've been injured but you're not).
Kyle, if you’re looking for science fiction that addresses near Lightspeed particle density, read anything by Alistair Reynolds. He is an excellent sci-fi author that started off as an astrophysicist and writes hard science fiction. His Revelation Space series has ships called lighthuggers, that travel as close as is humanly possible to the speed of light, and must be cone shaped and covered in shield ice to protect them during travel.
Use of pressure points is called pain compliance. If you mean like poking gripping certain areas, I don’t think you were talking about it for self defense but a rear naked choke is the one thing I can sorta see as making sense based on what you said- btw I took a title from you to describe the process of breaking down the processes of combat “fight physics” im keeping it :p
Hey Kyle, since you doing some dragonball content lately, I always wondered, is ultra instinct possible? Surely not the way goku transforms but for us humans, can we really move without any thoughts interfering? Are we going to be that much faster if we could achieve such a thing/state?
What's the physics behind movement without thought.
So a little of that is muscle memory.
Our reaction time would have to speed up
@@fire083 sure it could be, but constantly moving without any thoughts (eg. fear, hesitation, the chicken you left in the oven if you don't want to be that technical) interfering. I do belive that what you are referring to is some reactions that are just happening because you done that move/thing so many times.
I just wanna know if reacting without thinking in a fight is even possible.
Batters do this all the time. The time spent thinking about where the ball will be is enough time for you to miss it. You just have to trust that your body remembers the aiming from memory. Bruce Lee had a great way of explaining it in Enter The Dragon when he said "I do not hit, it hits all by itself." Meaning he doesn't think about what he is going to do, but through years of training, his body knows how to react based on the information his other senses are gathering without having to put them together. Which take nanoseconds, but a nanosecond could mean the difference in hitting and missing a target
Science Insider has a great video on how Batters hit fastballs. Not trying to plug other channels on here, but I think it will help with your question a bit.
you touched on that psuedo "shared nervous system" from a cyberpunk thing and all i can think about is
"What if you knew how many people were logged into Your neural network? can you turn it off or on so your not doing illicit things for those experiencing? how much of it is an invasion of privacy?" a thought experiment for sure and a creepy one to be sure.
Very disappointed the mantas shrimp did not attack....
On the pressure point topic; If you strike someones liver (which protrudes just under the rib cage) you can take out their legs. The liver is sort of like a balloon, if you squeeze one end, the other end will stretch. Apply enough pressure to the outermost side of the liver, by a swift punch for example, you can rupture the innermost side. This can damage a particular nerve which runs past the liver and down to the pelvis before splitting off down both legs. The damage to the liver then causes such pain to the legs that the person/victim/target will collapse. It has happened many times in Boxing, MMA and other Martial Arts sports and is a good self defence technique to use against "Angry Drunk" people who tend to throw wild Haymakers. Duck inside the range of the incoming punch and use your forward momentum to throw a close in punch just under the rib cage on your opponents right side (look up a diagram to see exactly where to hit) and you're golden. Even if you miss the target spot, you will still wind them enough to throw a rapid follow up strike, or throw. :)
11:04 - For all of us 'international viewers' you should use kph (kilometers per hour), which is a unit we understand and it makes sense.
There is something I learned about in my combat hapkido lessons called a brachial stun. You are essentially supposed to strike (it really doesn’t have to even be that hard for a stun) someone on the side of their neck as a counter attack. Though there are a lot of muscles, arteries, and nerves in the area, we normally just say “go for the brachial nerve” as slang. In reality, I think it is screwing with a single nerve we have in each side of our neck called a greater auricular nerve. One source I read states it’s like hitting your funny bone but for your entire body. The strike is done as a chop (avoid chops if it meant as a non serious blow as a chop or boney strike can really hurt someone’s neck), slap, or forearm strike across near where the carotid artery lies. It can do some serious damage instantaneously.
When going relativistic/near relativistic speeds, shape does matter. Having the "front" of your ship at an angle to direction of travel may be important. The reason for this is the same reason that a battle tank has angled armor. You can use less material to provide the same amount of shielding from "space dust" or perhaps even smaller particles.
I can confirm that pressure points can work. I was a camp counsellor for some older boys (12-15) one of them came up behind me and put me in a rear naked choke. I jammed my thumb into the soft spot behind his jaw. I intended to cause some discomfort causing a distraction so I could slip out. But I guess I surprised him and pushed very hard and caused so much unexpected pain that his body kind of shut down. He actually passed out and layed unconscious on the floor for about 15-20 seconds. It's the only time I've seen a pressure point actually knock someone out. Needless to say the rest of the cabin didn't try to wrestle with me for the rest of the summer.
4:00 I feel like there'd still need to be *some* shaping and design to consider so that thrust forces from propulsion are evenly distributed along the surface of the vessel. Imagine a kilometer-wide dinner-plate ship design with a single point of thrust in the center; the engine would just punch right through because the stress at the center would overcome the material strength. So, it can be any possible, fragile shape if it doesn't need to change direction, but if you wanna go *fast*, you'll have to start shaping the hull. Maybe an egg-shape with the engines centered in the back?
Lightspeed drag is a concept brought up in the Three-Body problem trilogy, volume 2 (The Dark Forest). Fantastic SF books, would recommend them heartily.
I believe the shooting spider web across the street question could be better solved considering the fact that spiders don't "shoot" so much as kite their web.
Some young spiders spread a line out into the air and when it is enough spread, the spider can glide for miles on the strand.
So you could begin by considering if the web needs to be propelled or if the sum of an arm maneuver and a specialized strand could be adequate.
If you want to improve your grip strength, Iron Mind makes some amazingly-difficult-to-close Captains of Crush grippers. Check 'em out if you're hardcore and/or want to really up your grip strength... I've managed to close the #1.5 exactly once with my dominant hand, and have to go back down to the 1.0 in order to actually do any reps. Most folks start with the S (sport) or T (trainer) levels. :)
I was thinking of the light making sound topic. Sure - light can transfer energy to physical materials, and if that material is a gas, then the light can create a thermal gradient, and bam.. you can have a hum to thunder depending on how quickly the gas moves and in what oscillating pattern as it expands due to rapid heating and cooling. But - I have also heard of (and seen on youtube) various 3d image projection tech (free air hologram type devices) that use arrays of lasers to ionize atmo gas at target points in space, to excite them in away that causes them to emit light, as well as to create a haptic interface point (one can feel the ionized plasma if one moves one’s finger to that point). That (or rapidly oscillating optical tweezers) could probably also be used to shunt gas molecules around, without actually heating them to the point of creating a pressure wave like thunder. Still a similar process, but I think closer to what might be a ‘room temperature’ way of using light to create sound. Talk about wireless speakers.. physical object-less sound projection technology would be pretty cool, and maybe would be useful in 3d holographic displays - make that hologram of a person appear to be projecting sound out of their hologram mouth with laser arrays.
And if anyone’s asking, the future-tech I’d love to see most is the sci-fi trope of the ‘autodoc’, which has appeared many places from Larry Niven to the Expanse (they call it “Expert Medical Systems” in the Expanse), I’m pretty sure Niven coined the term “AutoDoc”, but that term was used in Prometheus, and in Passengers among others. The idea of a box that a sick or injured person could be stuffed in to and it would automatically repair/cure them. Oh.. they were also used in a Friday the 13th movie that took place in space, and in that Matt Damon movie .. Elysium. They pop up a lot.
17:55 It has been theorized, by actual, serious scientists that light energy may influence and vibrate air particles (i.e. make sound). But, the question is probably asking whether visible light could make sound and while it might, possibly, theoretically be able to, the frequency of visible light in the sound spectrum is FAR outside the range of human hearing.
In another example of "going around the horns," however, audio speakers in effect convert electromagnetic energy (same as light) to mechanical energy - producing a vibration of air.
In regards to an instant pressure point I think there's a pretty reasonable argument to be made for the solar plexus. It's big enough to allow for a 1-2 knuckle "punch" that if delivered hard enough (which isn't very hard) will seriously knock the wind out of someone.
I haven't looked through the comments to see if this has been brought up but a powerful, Focused laser or two lasers Crossing each other can ionize the air and create a sustained plasma ball. You can vary the intensity of those lasers to cause the plasma ball to fluctuate and create sound like a speaker.
Ian Douglas' Star Carrier series describes human space ships shaped like giant mushrooms, with the cap of the mushroom as the forward end of the ship. This cap is filled with water, both as reaction mass for thrusters and as radiation shielding for relativistic travel. The stalk of the mushroom is the comparatively weak section of the ship, with hangars and living quarters, and any section with gravity is given gravity by rotational modules. It's overall really well thought out, and the relativistic physics of long distance space combat are taken into account as well.
It also touches on upcoming issues, such as AI, nanotech, cybernetic augmentation, and the societal impact of all of these
Ahw Kyle. I was just catching up on videos I missed over the years and I just land on one where you mention one of the ways I plan to use to kms.
mantis shrimp. i'd heard about them, seen em on tv a few times. but that eyeball stuff? wow. serious weird! :D very cool!
18:00 Light most likely could not do that because when it excites particles it excites them in random directions, so you could make heat but not sound because sound requires all particles to be moving in a general direction together as a pressure wave.
However a significantly powered one maybe? i don't know.
Hey kyle, huge fan, long time watcher - sometime comment person, going on the Spider-man web shooters I was under the impression that a specific muscle grouping is done in order to the almost metal rocker symbol just pointed in a certain direction. It's kind of like when you grip your thumb and pull you feel an immense tug on the tendons/muscles (pretty sure it's the tendons). you don't get that feeling unless your thumb is positioned in that way. Back to the shooters, doing that symbol would create a specific grouping that acts like a keyhole and your fingers are the key. Maybe this works, or my imagine has really kicked into high gear on this one. Hopefully I can obtain supernerd status. Using my immense Spider-man knowledge would be the only way to do it.
Judo teaches some wonderful strangles. They do work quickly, though you are very right, not neck pinch quickly. Very discreet answer, Kyle. As for the "pinch" exhibited in Star Trek, I always kind of wrote it off as a Vulcan thing. Since they mind meld, it seemed plausible that they were forcibly contacting a major nerve conduit and sending a mental "punch" to the consciousness to knock it out. Maybe just magnifying the pain of the physical "pinch" to unendurable levels.
They're also something like 5 times as strong as humans pound-for-pound, so perhaps their grips are just physically capable of generating enough force to pinch a major vein closed.
Jiu jitsu has great chokes (blood chokes) that shut your brain off quick
Of course it would. Judo is the "safer" child of jiu jitsu.
I always thought that as well that there was a mental component to the neckpinch seeing as outside of a certain Mel Brooks movie no human can do it 😁
Perhaps it is a kindof psychic mind-meld thing, but I believe it is stated somewhere that Vulcans have a neuro-venom they secret from their fingertips which allows the nerve pinch to work. Could also be the explanation for the mind meld, too.
Hey kyle, quick correction on the vulcan pinch. I know of one point (not on the neck) where if enough pressure is applied it can cause a person to pass out very quickly, and probably vomit. If youd like to know about it let me know and I can explain it. (Its something that is taught at police academies and departments world wide.)
The whole sound of light thing is a cool idea. You talked about lightning creating pressure waves from heat, but I think that the interaction between light and air could create a sound wave without heat. Since light is an EM wave it has both electric and magnetic fields. These fields do interact with the outside world, just in really small amounts. It would be theoretically possible to put enough energy into the light wave where the interaction of the electrons in atoms and the electric field of the light could create a sound wave. That is what I think at least, I could be wrong.
You don't need to go super fast to experience friction in space. You could just substitute it with going for very LONG. As you've mentioned, there are atoms in space, and each atom you hit along your way DOES transfer energy to you that is pointed in the opposite ditection from the way you are moving. This is friction. But it is such a miniscule impact that it would take hundreds, maybe thousands of years of moving to notice it.
13:36 Spider-Man episode Make a Wish, Spider-Man (1994 TV show) features Spider-Man meeting with a young girl named Tiana who is his biggest fan. He recounts how he got his power and he demonstrates how his webshooters work. Specifically, the trigger mechanism only activates when he uses his middle and ring finger and only when he applies a specific amount of pressure. This is to prevent them from accidently activating from him making a fist or grabbing an object.
Hey Kyle,
On the question, “Can light vibrate air molecules and produce some kind of sound?
To answer that: Lights is wave at the same time light is particle. Theoretically when light hits the air molecules there will be some sound as light itself is a particle. However, it would be so lean that our human ears won’t get it. Because our ears are not that sensitive. So even if it is a “Hum” we would not hear it.
What do you think?
Thanks for the making another wonderful video, big fan!
Something I figured out as a teenager was that if you push your thumb into the person's armpit, then put your fingers around their clavicle, the person experiences sufficient pain that they commonly drop to their knees. It's not the best replacement (your example of the carotid arteries being pinched -which is a form of choking, and the non-lethal way to do it [suffocation via reduction of air intake is lethal in most cases and can collapse the throat] but it does work to "drop" a person...
Just adendum: the sternum is a pressure point, press it hard enough and you may not only knock out someone, but outright kill.
Fuck yeah I always hoped you'd make a video on the Mantis Shrimp, that's such a cool animal and possibly my favourite
One thing that's always confused me about the Predators is the ornatenteness of their architecture, weapons and armor. How and why would a species that only sees in infra red make such detailed and almost artistic things when they don't have the vision to appreciate it?
Huh, I never thought of this, that's a very interesting point.
Tactile feedback value? I'm already building a head-canon that separates vision being for hunting and Not aesthetic, from artistic expression which is focused for other senses....
TheDeepDark Go for it, let me know what you come up with!
It's not choking someone out, it's strangulation. Choking is internal, strangulation is external. Many strangleholds are misnamed chokes, which is where the confusion arises
I keep forgetting about this!!!! I have like a dozen questions (only a couple decent ones, tbh) lined up to ask but never remember to get on in time.
I haven't tried pinching someone there however chopping or hitting that area on the shoulder with a flat fist will definitely "knock out " the opponent but more in a way that there muscles will instantly stop working and will most likely lead to them falling. it renders them useless for a few seconds and its extremely painful even after you regain mobility you still need a few more seconds to shake off the affects so if hit there you are as good as knocked out.
I know I’m late to the party but we actually use induction to weld the seams of steel tubing at the place I work. We also use induction to help galvanize and apply paint to the tubing which ,simply put, they are just an insulated box with copper coils inside and have an electrical current running through them.
Re: Spaceship designs and shapes.
In "The Bio of a Space Tyrant" sci-fi book series by Peirs Anthony, the argument that a perfect sphere is the "best shape" for interstellar craft is made. IIRC, the argument put forth is that it provides the greatest internal volume per unit of surface area and, for some reason, that was considered the most important. Any thoughts on that?
The question about light making sound made me think of the an episode of the show Pete and Pete where they race the other family and follow the sound of the high voltage electricity lines.
As far as the nerve pinch goes on the left lower side of your neck there’s a pressure point called “stomach 9” and if you hit it hard enough it sends a false signal to your brain that your blood pressure is really high, so it lowers your blood pressure and makes you pass out
21:45. I might be wrong about the video in question. But I'm pretty sure the metal reached the curie temperature and lost it's magnetism.
Also couldn't light energetic enough ionize the air and cause it to hum?
12:07 YOU KNOW HOW MUCH I SACRIFICED?!
@24:45, "You get Thundarr the Barbarian!"
For the lightning sound thing i think the sound comes from the change in energy not from the light. If the light acts on something or goes through a medium change and there is a disbursement of energy then it would create sound. Lightning being created or hitting a tree or person creates the sound. It going through an efficient conductor probably won't create sound. If you get enough energy I'm sure almost anything will create sound from the changes caused in the medium.
They say Mothra's wings create hurricanes, but I assume they just meant a vortex the size of a hurricane. Every wing creates vortices, heck anything that moves makes them, in some amount. We even make them at dangerous levels, a Cessna flying under a 747 getting caught in its wingtip vortices could be catastrophic. So I wouldn't be surprised if a Mothra like monster could make a vortex from each wing that is similar to a hurricane. It just wouldn't be sustainable at all.
7:40 Jack Bauer's signature move 😊
Well, the record human ejaculation distance is about 5.7 meters. That should about get you across a one lane street with side walks.
Jack Murphy i didn't know that and i did not need that information but thx.
Oh yeah I think I saw that Spider-Man movie on pornhub
Sploosh McCooch Spider-man home cumming if i remember correctly.
I have to say, I now have a horrified curiosity about how and, more importantly, *why* that record was made.
@@coryzilligen790 A month late but what he mean is penetration. It prove who genes is stronger if two male mates with the same women.
As for that spider web silk distance, there is a spider that will span rivers and streams but rely on the wind to carry the silk to the other side. Also, for light making a sound, a red-back spider researcher has put a reflective bead on a female spider's foot on the web while the male plucks the web, desperately trying not to get eaten while trying to copulate... I think that counts, since the web vibration is translated into sound by light reflections.
Aye Kyle! do you do grip strength exercises?! Do a collaboration with Jujimufu's channel while making it sciency and teach em a thing or two on how to set up experiments. I have a feeling it would be hilariously entertaining and informative
I instantly liked the video when Kyle showed the pressure points 😂
16:10 theorized but not proen--I remember chatting with friends of mine years ago while playing pen and paper Battletech and someone mentioning the 'pew pew' sounds are actually lasers punching through air in atmosphere...
21:00 the guy doesn't "turn off the electricity" iron looses it's magnetic properties above a certain temperature, so you can't magnetically levitate molten iron
The comic space boy from webtoons does that where they lose their shielding in space for a Split Second and everyone is irradiated and dies. Because they were traveling at such high velocity.
Brachial stuns are very quick to knock someone out if you were to strike someone the “correct” way. The nerve is temporarily traumatized so the signals to the brain are interrupted. Some boxing knockouts where the punch hits more on the neck than the jaw are a result of a brachial stun. When you can anticipate the strike, your brain can exclude the interruption and often avoid the knockout. It is like auditory exclusion from a gun shot or other loud noise, you hear it but it is not nearly as jarring than if you weren’t expecting it. It also explains why you can’t really do it to yourself.
That said, since Spock can meld into someone’s mind could he not just as easily temporarily interrupt the signal to the brain in the same fashion to incapacitate someone?
There is very rare phenomenon that occurs with the Aurora where exceptionally active or bright Auroras have created their own sound. While it isn't directly light creating these sounds, the excitation and ionization of the molecules that make up the Aurora is the source of the sound. Exceptionally bright or intensely focused light could theoretically create sound with its interaction with air molecules though.
What a supervillian execution method for Magneto to use.
Chiming in a year later (better late than never?) The block of metal drops not because the electromagnet is turned off, or the magnetic eddies can’t suspend a fluid (there was a commenter saying something in that ballpark) but because the metal gets heated up to it’s Curie point, where it is so hot that it is not able to be magnetized anymore.
Congratulations on getting questions you can answer!
There are actually river spiders that shoot all the way across to the other side to build their webs. So if that were scaled up without concern for how that scaling would actually work, or how it would fit in your hand, then it's actually quite feasible.
15:41 I would say light itself cannot make molecules vibrate since photons have no mass and are rather absorbed by other particles/cells. However, the energy produced by light - aka heat or electric energy - can. (I'm no scientist and I only did a few quick google searches so correct me if I'm wrong)
And I think the best example for people to understand in spaceship design is the Enterprise vs. Borg ships. All the Enterprises made to go in and out of atmosphere Borg ships are strictly spaceships so they can be giant cubes
Kyle, or random comment reader, have you watched any of Isaac Arthur's CZcams videos? He does videos on mega-scale engineering projects like interstellar colony ships, space highways, and Shkadov thrusters. Also he has a few videos on the effects of going really fast, this space friction you mention is just part of the problem of going really fast.
The sense-net tech is terrifying, if you can't think of why here's two examples: imagine someone wearing while they die and you being tricked into "viewing" that experience and the second is the plot of the 1995 movie Strange Days.
18:01 Well you kinda forgot some of the powerful lasers in the world, like neon and argon lasers. These lasers use photons (aka. light) to energize a pressurized gas, (aka air) until it is able to emit photons in a specific frequency. These lasers CAN be known to make sounds, although they are far too faint for the human ear to hear.
@BecauseScience 8:14 - Regarding pressure points, there are two I know of that can knock a person unconscious INSTANTLY when struck, because hitting these points overloads your central nervous or circulatory system & your brain shuts down (If only for a moment or two).
***WARNING: MISUSING THESE STRIKES/POINTS CAN LEAD TO SERIOUS & PERMANENT NERVE DAMAGE***
The first one is on the inside of your arm just below your armpit which ninjutsu practitioners learn to strike with a sharp modified punch (Feel around there with your fingers applying GENTLE pressure & you will soon locate the area)
The second is located on your inner thigh just below the groin, almost exactly the same layout as the arm point. Once again, a sharp kick to this location can result in instant unconsciousness. If you have a look around for quickest/greatest UFC KO's there is a documented example of this occuring, it was the ONLY strike that connected so not a result of other injury/damage.

Speaking as someone who had only one functioning eye before he went blind, I think it worth noting that while their are binocular cues that contribute to depth perception, such as paralax, there are also monocular cues and that having one functional eye doesn't necessarily mean an absence of depth perception.
Also, something I've been wondering for a while, but if you had a spaceship that was pyrodynamic/plasmadynamic/whatever the plasma equivalent to aerodynamic/hydrodynamic would be enough to slice through not only the inter-planetary/stellar/galactic medium, but even the dense plasma of stars at relativistic speeds without the plasma acting like a brick wall ala hitting a body of water head on at terminal velocity, and the ship was sturdy enough to handle the pressures inside a star, would the time it takes to cross a stellar diameter at light speed even be long enough to cook the occupants of the ship? Alternatively, would such a trip be long enough for the pressures to have time to crush a ship that couldn't handle the pressure?
The queston voice is guetting more confident, i like it!
