How to pronounce “brightness” in English

supernova called a type 1A Supernova that is always more or less the samebrightness and that's because it comes about from a picture like you see in the upper left here you have a white dwarfstar that's a star that is given up on fusing um light elements in its core it

The occluding contour algorithm is based on a branch of computer vision called shape from shading.The brightness in an image, like a photograph, will depend upon the direction of illumination and the normal, the perpendicular,line at a given surface.

Size might be in the form of maybe mass if it's a dynamical detection, maybe radius,or brightness-- those are all indications of how big a planet is.Temperature is how close the planet is orbiting to its parent star.

And for a small subset of the targets, 512 at any one time, it would send more frequent measurements.The brightness measurements were done every minute.So you could do additional science, that I'll tell you about in a few minutes.

feeling your back and neck coming into alignment, and noticing, perhaps, a background senseof brightness or wakefulness that comes into awareness when you do that.Good. Now just invite your entire body to relax.

nits now. Not that the 2,200 from last year was terrible, but you know, that's a nice little bump. I've noticed it. Itseems like the brightness slider was in mostly lower brightness, and then the last quarter of the slider was extremelybright. Maybe that's just me, or maybe they got some tweaking to do there. But then this thing also gets faster 25-W Qi

So we still get...higher peak brightness numbers and contrast ratios and occasionally special features like the privacy display in the bleeding-edge phones.But for the most part now... in flagships, they have great displays.

brightness versus time. And I want to impress upon you the numbers here on the vertical axis. These are very tinychanges in brightness that we are now capable of measuring. So this particular star got fainter. You know, a fewnumbers in the fourth decimal place. The brightness went down by just this tiny little amount. That tells us we're dealing with a roughly Earth-sized

conditions. So that's the Mustafar like planet from uh from that third Star Warsthese dips the brightness of the star goes down by more than 15% in this case 20%.

This is a month's worth of data from a satellite called Kepler which, for three years, stared at 150,000 stars,measuring their brightness every 29 minutes.This is a month's worth of data.

It's reasonably quiescent. But if you're overfeed a black hole, then things can happen.So this brightness against time for a particular star-- one of the 150,000 stars that the Kepler satellite

Do you guys cook for your kids?It adds a little brightness.

And it's really important to add enough salt and enough fat-- sorry, we're switching-- An acid Acid, yeah.--to get that brightness.Yeah exactly. So all of these recipes generally have some kind of fat or acid-- sorry.

Remember the last one, it was like four decimal places?This one drop in brightness here is only about a percent.And this system I wanted to tell you about because the field now is doing what's easy, not what we necessarily wanted to do.

And so that meant not only looking at the images, but then looking at them over time.So you assess the brightness in one image, but then you keep assessing it as you look at subsequent photographs.And this is the small Magellanic Cloud, which is not visible at all from the northern hemisphere.

And it's a wonderful thing to write a lyric because you have this prompt.the only brightness beneath the trees.

Basically what Kepler did was monitor the brightness of 150,000 specifically selected stars in this fieldand just monitor their brightness over time, very, very precise measurements of the brightness.Because it's in an Earth-trailing orbit, it's too far away to download all these huge images all the time because it's taking measurements for those 150,000

If it needs more salt, decide whether or not you want to add a bit more acid.If it needs brightness, you can add a little more red wine vinegar or lemon juice, and that will actually bring up a little more sodium.

do to bring brightness, color to a stop-motion feature.

The measurement of the brightness is easy, but how do you know the luminosity?

We know its apparent brightness.

We measure the apparent brightness of the supernova.

into the sudden brightness of the operating theater.

we can monitor the brightness of the star. And as the planet goes across, the star just gets ever-so-slightly fainter. You know on the order of a percent or a half

And the measured brightnesses were fainter than expected.

With some of them look on brightness and more on, on the other on colors, right? So we need to compress a lot, and so we need to degrade. But in order to

And the thicker volume and brightness sliders in quick settings and just a bunch of other subtle tweaks that, you know, they're nothing game-changing but

And then you get the brightness of this little herb salad and chili on top, and then a pinch of the-- Toasted--

I won't go through all the physics, the so-called forward model.We have the 1 over R squared brightness dependency, the so-called Lambert's cosine law and so forth.There's a lot of math.

And so we measure the brightness as well as the-- so the brightness and the darkness.

The rice vinegar gives you a brightness, the sourness.

So lots of colors and brightness.

We're just going to add some brightness and some crunch to the salad through some green onion.

If it's moving a little, then actually we get a different response.And what we're measuring about the brightness of the star isn't actually the brightness about the star, it's really just something that'shappening on the detector.

But do you see a planet?There's a drop in brightness as the planet goes in front of the star.And it's all compressed, because here you're seeing relative brightness, and at the bottom you're seeing time, which it should have said on here, days.

OK? And one person in this building goes to the window and lowers the blinds by about a centimeter.That's the change in brightness we have to measure.So that means that we need part per million precision, exquisite stability of our spacecraft to move our instruments in order to see this.

Like I said, we measure the dimming of light as depicted here on the left-- that's real Kepler data.Every white point is a brightness measurement that tells us the radius.We go to our ground-based telescopes, the Keck 10-meter telescope in particular, and we measured the Doppler wobble-- that's what's being depicted on the right.

So what we actually observe is very complex and full of information.On the upper swath are the brightness measurements that Kepler takes.And there are some arrows to help your eye.

Here it's shown near the constellation Cygnus, also known as the Northern Cross.Basically what Kepler did was monitor the brightness of 150,000 specifically selected stars in this fieldand just monitor their brightness over time, very, very precise measurements of the brightness.

And these boiling motions create sound waves, well below the range of human hearing, that propagate down into the star and set up standing wavesthat you can view as brightness variations on the surface, exactly the kind of measurements that Kepler is already making.And that's the motivation for Kepler to be sampling at the one minute cadence because these variations in brightness due to the seismology signal operate

and creates these sound waves.So these sort of measurements of the brightness variations caused by the stellar seismology signal tell us very straightforwardly the absolute sizeof the star and also its age.

Though when you have a lot of brightness in the middle, you start to see that.

We cook with a lot of brightness.

So just look at its brightness change, the way that, as it rotates, depending on the geometry, if we're lucky, as it rotates, and we

So the cones are producing the brightness information as well as the color information.

I think it was $15 for 108 brightness and 32 pound paper, whatever it happens to be.

You look at the relative brightnesses of the headlights and you use the inverse square law in your mind.

we scale down the resolution of the color compared to the brightness.

But if you're at a high enough brightness, you will actually see it get a little dimmer when you turn the feature on.
