    1 - you can cut ice with a blunt diamond because it is such a good conductor of heat
    2 - The filament in an old fashioned incandescent light bulb is a helix of a helix - a meta helix!
    3 - Some vampire bats mimic chicks so they can snuggle up to a hen's brood patch and drink her blood.
    4 - The word "second", as in the length of time comes from the fact that it is the second time we subdivide the hour into smaller units. The first time being minutes. So why aren't minutes called firsts?
    5 - Most owls have asymmetrical ears. It helps them to figure out the direction of its prey by sound. The asymmetry causes an interaural intensity difference that the owl can use to figure out the origin of sound in the vertical plane.
    Here's Bill Schutt's articles about vampire bat behaviour: www.naturalhistorymag.com/feat...
    Thanks to Dr. Kelly Williams for her photograph of the inside of an owl's ear (at 8:12).

Anyway generally we call them minuti if it's time related, and primi if it's angle related.

      Duh? Minute and minute are pronounced differently, have different meanings (One means small and one is on the smaller side of time measurement, but how often do we name something small just because it's kind of small? Minutes aren't even close to the smallest measurement of time), and other words that share the same spelling don't always have the same root meaning. Don't be an ass, there's almost always a decent reason for not knowing something, and stroking your ego makes you look arrogant and, frankly, dumb.

    @Steve Mould , I'd love to see a video on how they make a meta-helix filament (out of superhard Tungsten to make things more difficult) so it doesn't short with itself anywhere along the length.

  • @_WhiteMage
    @_WhiteMage 27 днів тому

    2:10 You can make your own meta-helix by twisting a strand! Take a long piece of floss, hold either end, and twist them opposite directions. With enough twists they'll naturally fold into a helix of about half the size. You can then take those ends and do it again and again, halving the length and doubling the thickness every time. You can make a pretty thick rope out of anything like that. It's an interesting experiment.

    Another interesting thing about vampire bats: they often drink so much blood that they are too heavy to fly. So they run around on the ground, weeing out the excess liquid and flapping their wings, until they're light enough to take off.

    We can tell if a sound is up or down or behind or in front where the tone of arrival is the same because the sound is filtered by the ear flaps. The shapes of the ear make this possible. But it requires more processing power and larger solid ears, both things you can't easily fit to an owl. Needs to be light weight.

    The thing about not noticing that the time measurement and the ordinal number are both called "second" reminds me that English will use the same word for 2 things that have 2 different words in other languages. Like in English "to return" can mean like "I returned from work" or "I returned the book", but I'm Spanish, one of those returns would be (a conjugation of) "regresar" and the other would be "devolver"

My brain knew the right spelling but also just thought it was the beetle insect. It wasn't until I searched on something about The Beatles and I had to type it... "Hey... wait a minute... beat... COOL!" I'd never needed to spell Beatles before. Crazy how the brain works.

  • @TLguitar
    @TLguitar Рік тому

    It's worth noting that we humans of course do recognize elevation differences in sound sources (and back/forth placement) and to my understanding it has to do with how the pinna-the outer ear-along with the rest of our body (skull, torso) filter different sound frequencies differently versus how they sound when entering the ear more directly, and apparently it works well enough only if the sound in question is complex enough. I tried moving a simple sine wave vertically and indeed it didn't seem to affect its perceived elevation.
    One study mentions giving participants silicone ear moulds which effectively change the outer ears' shape, and indeed all participants had lost their vertical auditory spatial perception at first, but what's interesting is that most also regained it with the moulds completely or partially after wearing them for several days.

  • @sicko_the_ew
    @sicko_the_ew 4 роки тому

    I think the shreik of a barn owl might be some kind of hunting tool. (Maybe they can filter out that sound from their own hearing or something?) The reason I think so is I used to have barn owls roosting right outside my bedroom window (on a roof truss of a verandah out there - so almost against the wall, and only about 2m from the window - at most; but this part is irrelevant.) Every night they would fly down the sides of my cottage, shreiking all the way down the length of the building. They would do it down both long sides, and would not do it in the surrounding bush. I got so used to this shreik, incoming, running down the side of the building, and then ending on the other side that it became a strange kind of lullaby. Owls were doing their usual thing, so everything's all right.
    Perhaps they try to give still mice in the grass a fright, and make them start. Then if they had a way of hearing that movement in the grass, they'd know where some prey was.
    A sample of two owls isn't significant, but it might be interesting to find out what a larger number of barn owls with available walls to shriek past did. (ie first step: find out if this is a common behaviour/ an actual, rather than just perceived behaviour).
