In Portuguese, the word for 'cousin' is 'primo', which also comes from the Latin 'primus', as it is the first cousin. But get this: It is also the word for 'prime', as in 'prime number', and there is a subset of primes called 'cousin primes'. Now, I don't really know what cousin primes are called in Portuguese, but I would have to guess that it's 'primos primos', and I kind of love it.

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.

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"

Minutes / Seconds - also used to subdivide degrees; as in 'minute of arc' and 'arcseconds'. The former being used in marksmanship, the latter, astronomy.

Maybe the wings also act like an extended acoustic cup , like a dome mirror /concave skylight/lens for light focusing sound into a point!

I did not know about the thermal conductivity of diamond, very interesting. Most people don't use diamond for much of anything because of the cost lol

There is another use of second in sports and military. In Swedish we have a "Sekond" meaning 2nd in command which is XO in english, Executive Officer. Maybe not a primary use of seconds but hey, good to know. =)

the second thing is awesome. i remember trying to figure out the minute/minute second/second thing in elementary school, and just not figuring it out. i hadn't really thought about it again until now, but it makes sense that both minute and second share the same latin source as minute and second. super interesting

Those were awesome. Thanks.

The bat pierces the skin with an analgesic and anticoagulant then drinks the blood as you mentioned with capillary action and in the hen's case with gravity assistance.

I had learned that the word second is related to the ordinal, but only because _secondary_ is related to the ordinal. Thus it's not because it's the second time it's subdivided, but instead it's the _less important time_ it's subdivided. The subdivision is secondary in importance. It matters less than the primary subdivision.

0:49 It could be a great segue into how lasers work by focusing light power into a very tiny spot. There seems to be a lovely relationship between these incredible ways in which energy is focused/diffused.

Thanks for another amazingly good video Mr. Mould. I don't have any nitpicks this time.

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.

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).

Every one of these episodes blows my mind somehow.

I really like these videos, I love learning new, fun facts. Just Awesome, thank you.

Honestly, when you said we use time differences to realize where a sound comes from, I never thought of it before. As I only have one functioning ear, I believed you notice only through difference in volume of sound from where the sound's from, never considered the inconsistency of the sound from both ears albeit as miniscule as it may be

@pologutierrez5419

Жыл бұрын

If that inconsistency is perceivable it is only detected and processed unconsciously by our brain. We can't really "counsciously" perceive the delay between the sound coming into one ear before the other. I think it is mostly the difference in volume from one side compared to the other that tells us de direction from which a sound came.

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.

In Greece we use the word "λεπτά" for minutes and "δευτερό-λεπτα" for seconds. The word "δεύτερος" means second in place and comes from the word "δύο" which is two. ("λεπτό"-"λεπτά" is something small or thin)

Other interesting things about owl eyes is that they are oblong. This also means that they can't swivel in the eye-socket, so owls can only look straight ahead. That's probably why they're so good at turning their necks.

At least this owl has also asymmetric pupils. See at 6:30 how the pupil (black center) in the bird's right eye is clearly larger than in the left eye. Well - it 's because the pupil of the right eye is in the shade but the left is in direct light.

Interestingly enough, in greek we use the term "second-minutes" to describe the seconds (and yes, minutes are fully called "first"-minutes).
