How to pronounce “velocities” in English

So high-low numbers in notes is high and low on a score.And velocities, you know, we have forte to piano.We have these kind of traditional markings.

the star to do a small orbit. So this is an example of this kind of data.The velocities that you have to be able to measure for this are measured in meters per second. So you know you can walk a few meters persecond. So we're able, we're able with Keck Observatory to measure velocities to one meter per second on stars that are typically 20 or 30 light years away.

know how to pick out the signal so this is you must have all seen this was just incredible I really did not imagine itfounded the velocities of the galaxies that were going around they were held together by the gravity of something and he realized that there had to be some

And then of course, we ended up landing somewhere else.What relative velocities are we talking about between the Lander and the comet in the next-- Very good question.Actually, the relative flyby velocities that we have on the Rosetta are extremely low for a space mission.

What we're really measuring is the structure of the density of stars as you get further away from the Galactic Center, and as you get further awayAnd the velocities of these stars are much smaller than that.

So this is as close as we've gotten. It's a 22-solar mass planet.And these are the velocities that when they're phased together show that this planet is, has an orbit around the star. And this is the motion induced in the starby the planet. And instead of having a 365-day period like the earth, a year on this planet is only 2.6 days.

So we get to-- after that, we turn this the spacecraft off, spin it up, and pray.And that is particularly bad when the velocities of the gas escaping a low, which happens when you're furthest away from the sun.

And we can time how long it's getting fainter along the edge and that gives us the radius of the planet. So we have the mass of the planet from usingNewton's laws and the velocities. And we have the radius of the planet, so that's gives us a density. And we're able to get a few other clues as to the properties ofthe planet. So we can start to talk about what the planets are composed of because density changes dramatically if you make something out of hydrogen and

We did an episode about the Greek Fates.Gaia looked at-- you're right-- positions and velocities of stars in the Milky Way, and gave us the most accurate map of stars in the galaxy

If you zoom in on it at optical wavelengths with the Hubble Space Telescope, you see that the inside has this optical jet.It's a jet of material ejected at very high velocities.It looks one-sided because this side is actually aimed towards us, and therefore appears brighter.

I better show it to you let's see.So random notes, random velocities, random time intervals, but the velocities are sorted largest to smallest.So they start loud, and then they get quieter.

What relative velocities are we talking about between the Lander and the comet in the next-- Very good question.Actually, the relative flyby velocities that we have on the Rosetta are extremely low for a space mission.Generally, if that's the Sun and this is the comet, the spacecraft flies on the sunward side.

And I'm going to go back and forth.You see why they might have different batted ball velocities and trajectories.

And I'm going to go back and forth.But what we have on the bottom is batted ball velocities, but these are average.

And I'm going to go back and forth.That is a big range of batted ball velocities.

They tend to be very similar.But since these particles are correlated and they're moving with velocities that are similar to that of their neighbors, they're not dissipating too much energybecause they don't have too much friction, or interactions that are not happening at speeds that are highly dissimilar between these two

OK, I need a brave soul here.You express your valve state through positions and velocities, and gas mass above and below the piston.

other galaxies but it's expanding so what does that mean what it means operationally for Hubble Is that he figured out how far away the galaxieswere and other people had measured their recession velocities galaxies it turns out are moving away from usthat was known before Hubble but what people didn't know is whether or not that just meant that they were being kicked out of our galaxy or whe they

If their velocity is dead constant, they probably don't have planets around them.But if we see periodic motions in their velocities, it means that a planet is orbiting around, around that star. And that its gravitational influence has causedthe star to do a small orbit. So this is an example of this kind of data.

This tool was first introduced in an attempt to solve one of the hardest unsolved problems in physics, the three-body problem.That is if you have three bodies and you know their initial positions and velocities, how will they move under the influence of each other's gravity?- It's a juicy, juicy problem, which occupied literally generations, hundreds and hundreds of years of incredibly ambitious, talented mathematicians,

The universe we live in is very different.In the 1920s, astronomers measured the velocities of distant galaxies, and they realized all of them are moving away from us.The farther away they are, the faster they're moving.

will think its final thought by the 50th floor because it will burn up in its own entropic waste generatedYou tell me the positions of the particles now, you tell me their velocities, and then you just turn the Newtonian crank,

So you'll see that it's a class that is really just three lists.There's a list of notes, a list of velocities-- it's a little confusing here.Velocity here means volume, basically.

And I think that's what it's for.Yes. So here you've got notes, velocities, and time intervals to represent a sound.How easy or hard is that to transcribe to something with multiple instruments, like the first piece that you did?

And by assigning that velocity to a note, the ratios of those velocities, he was able to come up with these scales.

are moving willy nilly.And even though they encode technically a lot of information in their quantum states or in the positions and velocities that they have,they do not encode much order.

physics, uh, when she observed the velocities of these stars, uh, all the way to the very edge -- in fact she went -- they had a good enough instrument

And this process releases a huge amount of energy and heat, and it shoots off the products at high velocities.

physicist billiards where balls just bump into each other and so forth, you can solve the problem of these two balls are moving with certain velocities.

But it's the same basic idea that you can look in different configurations, places, or velocities and see the same underlying structure.

of you you can prove what is it, the Thompson's experiment, the thing about the droplets moving at these discrete velocities, and that there's

Wanting to do it, yearning to do it, physically unable to bring ourselves to change our velocities.

The velocities that you have to be able to measure for this are measured in meters per second. So you know you can walk a few meters persecond. So we're able, we're able with Keck Observatory to measure velocities to one meter per second on stars that are typically 20 or 30 light years away.We have a very complex, very high dispersion spectrograph called high-res that takes the light of a nearby star, it divides it

in accelerations as they go close in. You can see them just whipping around there.This will just -- this will just replay. And this star here is -- they're all extremely interesting at these velocities or this fast, but the star that's most interesting is thisone here. It goes very close to the center of our galaxy.

And this is the very center of the galaxy, you can see.This is a tiny area, only .1 arc seconds. Now watch the stars as they go close to that, to the very center on their elliptical orbit. They're accelerated to huge, huge velocitiesin accelerations as they go close in. You can see them just whipping around there.
