When they were first talking about flicking tiny "beings", I misheard, and thought they were talking about flicking tiny "beans" and was confused and amused.
@Dude Gupta You’re lucky. Back in the days, in my school, they intentionally held the smart kids back. The motto was "what not everyone can learn, no one should be taught". Yeah, socialism sucks.
Well, you must be in a really good school, because most of the time it's only compulsory to follow the rules and not ask any questions. Being smart is at _best_ optional and most commonly actively discouraged.
There should be a Nobel Prize category for the person who watched this footage, furrowed their brows and said "This needs some 'boing' sound effects..."
Just started watching your channel and I have to say, you’re very well spoken and it’s soothing. It’d be great to have a conversation with you! But great video from the both of you
you guys are always really good at giving us examples to help us understand the scale-the comparison between the flips and the helicopter blade was especially mind boggling for me. thanks!!
love this! being 5 feet tall myself, I ran track & field in HS and was one of the fastest in the state at the 100 meter dash. Thank you tiny beings for making us less tall beings feel good about ourselves lol
Why do they all flip so much? Does it improve their aerodynamics? Wouldn't they be even faster if they converted all that energy into kinetic energy alone rather than angular momentum?
Yes but they should jump in such a way that the force pushing them from ground should pass through there center of mass. But they are not rigid bodies it's hard for them to master in that way !
And they aren't adjusting the acceleration "to scale" they are giving us real m/s^2 not shrinking down the definition of a meter for what a bug might call a meter. Lol.
@@TheSkystrider Yup... "It accelerates at an amazing rate of 700m/s^2!" but actually wait 1 second and it's now stationary 10 cm away from where it started
Hey note that the planthoppers are also using actual gears too to level their jumps out and prevent one spring from releasing before the other so both legs contribute to the same motion
Four species of ants live in and around my house in Mindanao Philippines. One of them, known locally as "aliwarang", accelerate like a bi-turbo sports car. The other three species are positively pedestrian by comparison.
Outstanding video Joe. As always, it was expertly narrated and informative. Also, I think it was such a good idea for you to call-out to Diane. She's a great communicator, very smart and very engaging. Really well done Joe!
_"According to all known laws of aviation, there is no way a bee should be able to fly. Its wings are too small to get its fat little body off the ground. The bee, of course, flies anyway because bees don’t care what humans think is impossible."_
old news, learned back in the 80s that its the way they use their wings. they entered the other old adage "its not the size the counts, but you you use it" category.
Noob question, shouldn’t we be using the term “quick” as opposed to “fast” when comparing these creatures and objects in this video? Quick is the acceleration, where as fast is the velocity.
If you want the physics, the reason these tiny insects can accelerate so fast is they have very little weight or mass. Force equals mass times acceleration or to use a bit of algebra, acceleration equals Force divided by mass. The smaller the mass the faster the acceleration. These insects weigh a fraction of a gram. So with a small amount of force they can accelerate very fast. An elephant has a lot of mass so even with a lot of force he accelerates rather slowly but not as slowly as an oil tanker which has an unbelievable amount of mass. Electrons weigh far less than these insects so electrons without much force can accelerate to near the speed of light.
And the reason the ratio between force and mass is going down as lengths get smaller is that the first scales like the square of the length while the second scales like the cube.
I'm always impressed that when you flick a common house fly it starts flying again after a minute as if nothing had happend. The impact of a human finger would squash us humans on the spot if a huge finger was about to flick us.
Acceleration is not speed. By that definition rockets are slow. By that logic I can easily clap or shake my hands faster or snap my fingers faster than any rocket.
How do they do it? Energy: Requires very little energy because mass (which translates to inertia) is low. Strength: G's affect mass the same, but mass is low, so they don't die. Physics: Mass is very tied in with physics (inertia/momentum, gravity, time-space, magnetism, light, etc) so in general, if you change the object's shape, substance, or in this case mass, you invariably change its properties.
Except the part when she has to explain what is a spring and how it works as if no one ever saw one and they can only be captured in the wild , it’s a very cool video.
@@buzzlightyear6960 Actually, I was waiting for someone to say that to me. I'm a person who gets paranoid easily. Till this day because of cockroaches alone, I'll sometimes scream just because I heard a noise near me that I thought might've come from a roach. I also never step into places without caution and I check my meals aggressively before eating them incase an intruder accidentally got cooked in it. Worst of all, I stay up till the morning for an entire week whenever a cockroach has entered my bedroom incase it's still around or incase there are more. Therefore, if a roach was ever to touch me or crawl on me or even bite me, that could cause me to become even more paranoid. First let's talk about if a cockroach were to bite me (and they do bite), if simple alcohol didn't fix the issue whether it was because the bite wasn't properly cleaned or so on, I would become very sick and get a bad infection that would be very problematic, especially for my already poor family which already has to borrow money for groceries because it would be hard to get me to the hospital. This event would also worsen my paranoia. Now let's talk about if it were to crawl on me. It is similar to the biting in the sense that it would make me more paranoid than ever. Maybe this would fade but not when I'm an adult and living in my own shelter. If a cockroach were to be nearby in my settlement when I'm older, it would cause me to lack sleep because I'd have to keep an eye on it. Lacking sleep would worsen my job productivity or even studies. My actions could also disrupt my romantic partnership with someone. All of these could become a factor leading into me having a worse off lifestyle. Since for quite a while I will live alone, and far from my friends and family, I could become depressed because of my terrible lifestyle. (Since I've been lacking sleep and other much needed things). And depression doesn't lead to a good place. I could lose even more productivity, lose or waste a lot of money and gorge myself in food for comfort. My life for a while would be a sad mess. Lastly, giving me a 1/2 chance of ending my own life. If I do choose to end it, then cockroaches, therefore will become a small factor in my own end.
I like the poetic symbolism at 10:00, wherein the only way to manipulate a shutter at that speed is making it's focus a lot smaller. So in order to film something very small moving very fast, you need to film it very fast but also very small.
@@snek8421 no, they aren't. They accelerate incredibly fast, but these animals are not moving at over 200 mph(320kph). Yes, I'm being pedantic, and regardless how fast an termite's mandible moves, that is not the same thing as the animal as a whole. I mean, I get the point of what they're "selling" in this video, but it's a bit of a bait and switch; after all "the animal with the fastest/quickest body part" isn't quite as clickable. (and I will agree that these animal parts ARE the fastest animal bits)
You can get even more energy release speed by peeling a regular plastic sticky tape reel. As you pull on the end of the tape to get a piece for some repair or sealing purpose, the thin layer of glue at the edge of the tape still on the reel stretches an enormous amount for its size and then tears and snaps back flat onto the piece of tape in your hand. This sudden release is so fast that it will cause a black body light release for an object at 100,000 degrees C - more than 10 times the temperature on the surface of the Sun!!! - creating a dim, very thin line of visible light (in a perfectly dark room where you have let your eyes' irises open to maximum and you look very closely at the tape) where you are peeling it AND ALSO A FLASH OF SOFT X-RAYS!!! Nobody ever anticipated this until somebody noticed the dim light and they used a multispectral camera to see what was being released. The Universe is a CRAZY thing!
Video starts Dianna: Hey...recording! Joe: yeah My brain: it was too quick I was thinking that video would start with an intro Me: hey brain it's okay to be smart.
I could watch super slo-mo video clips of tiny bugs flinging themselves all day, so long as they included the goofy sound effects you guys have put in.
@3:14 "just flick it" sounds like extreme violence. And the sad dramatic 80's style video right after that shows just how harsh the scientific world is.(I'm just joking ofc and I loved this video)
Well they also reach the fastest peak velocities of all animals. They may not be the fastest consistently but at the immediate point at which they are at their fastest, they are faster than all other animals on the planet.
@Pol Gabaldon That's a distinction without a difference. Speed is just a ratio of distance traveled to time elapsed. Something is fast if it goes far quickly, period.
"Humans have reached some pretty impressive speeds..." While the fastest land and air vehicles are impressive (because you can't just put a more powerful engine into the vehicle and go faster), I still don't think they hold a candle to the world speed record on a human powered bicycle: 183.9 miles per hour (296 km per hour)! That's just insane! back to the video... richard --
