And then simultaneously, I also had the experience countless times where I would be introduced to just a phenomenal woman who had stellar academic credentials, who had worked in a super hot company, led an IPO, whatever it might be.But then she dropped out of the workforce after the birth of her second or third child, and then wanted to get back in at some point.
dimensions and you know they stretch our puny little brains past the breaking Stellar because wormholes are his thing and who am I to say that that wormholes
variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. Stellarators are actually my favorite. So we'll talk about those.
And that allowed us to predict what the star formation rate should be across more than an order of magnitude in stellar mass, and back to redshift four, and even higher. So back over most of the history of the universe.
The stars grow, although they're not growing in the center. The stellar mass is constant in the center. But in the larger galaxy, the stars continue to grow.
So the big difference here is that when you have a Byzantine failure, the failed node, it can actually change its vote. But Stellar is not going to agree to something unless one of the other one does.
anyway, to do research for this book-- I collected all of the WPA guides that had been made in the 1930s because they were stellar pieces of literature. You get the guide for Iowa or the guide for Oregon, made in the 1930s and the early 1940s, financed by the government, to give work
Thatís the first magnetic drive, so thatís the ancestor of your hard disc. of stellar evolution codes, looking at the evolution of stars over billions of years.
And we ended up moving to Inglewood, California, where I transferred to play at El Camino Junior College in Torrance. After a stellar year at El Camino, my first year back in pads after a four-year hiatus, I went through the recruiting process again. I accepted a scholarship at Texas Tech University.
It's a quite different skill set. And she was stellar when I was a young person.
You have to find a use for yourself. I needed a stellar system that's 10 light years away.
Thank you so much for coming today. But whenever he got stellar marks, his father was still, oh, Dane could have been better.
is what's really controlling star formation in at least many of the dark matter halos, hosting star-forming galaxies. We called this Stellar Halo Accretion Rate Co-evolution, or SHARC for short. There's a kind of model that theorists make that we call bathtub models of galaxy formation and, of course, I put the SHARC in the bathtub.
So this is what it is for nearby galaxies, and more distant galaxies. This is the stellar mass of the galaxy and the star formation rate, number of stars formed per year, stellar mass formed per year. And what you see is that, at least at the lower-mass end, we're pretty much proportional to this plot, which is the star formation rate just growing linearly with the mass.
And there's a simple derivation that shows that the rate at which stars form, as long as there isn't much change in the that plot that I showed you a minute ago-- this plot, which is stellar mass versus halo mass-- as long as there isn't much change with redshift, then it's going to be governed by this term. So the star formation rate, the MstarDT, is DMstar, the Mhalo, the MhaloDT.
And he's published a big catalog. 80% of the stellar mass density of star forming galaxies is in irregular systems, not disks and not spheroid.
So the big difference here is that when you have a Byzantine failure, the failed node, it can actually change its vote. So the Stellar Consensus Protocol, it's obviously the first general FBA protocol.
Here's the most powerful lasers over time. And the stellar background, you say, what about the star?
It just depends how thick the clouds are whether you keep observing through the clouds or you have to stop because there's just nothing coming So the concept of stellar archaeology is correct.
It just depends how thick the clouds are whether you keep observing through the clouds or you have to stop because there's just nothing coming But for stellar archaeology, that's a big no no because then we can't transfer anymore what we see today to what the composition was before.
And sense how you're feeling. She was a stellar performer.
It opened up for the Icelandic banks, simply because of this very nice feature. They had a stellar credit rating that was largely inherited by the Icelandic state, which was virtually debt-free at the time, but they were also willing to pay high interest rates at the level of other emerging-market institutions a with lower credit rating.
know had a a stellar reputation out there. We clearly had our own problems.
not exactly a stellar PR strategy as for the kids only a few
variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. - The tokamak and the stellarator are both magnetic systems. Their goal is to generate this magnetic field and hold onto the fusion fuel long enough. Like I mentioned,
While Zeiss was doing a stellar job with the optics, ASML was still struggling with the power source.
And the Orion nebula is our nearest stellar nursery to the Sun.
So Nikhil and Kunal are two stellar musicians, and I'm really proud to be friends with them.
They're one of our stellar partners in the world of what we do here at Google.
On the left-hand side of this diagram the stellar mass is less than the dark matter mass in the center of the galaxy. On the right-hand side the stellar mass is the dominant part, the more star-dominated. More dark-matter-dominated on this side.
And she developed her own stellar classification system which was much more complicated than Mrs. Fleming's.
Cosmic scales and basically the Stellar extent of the Galaxy is already the size of the Earth and it's like having a
of a galaxy that the Stellar component is just the tip of the iceberg it's uh 5 to 10% of the total mass of the Galaxy
definitely try to Showcase those really Stellar stories wonderful absolutely and so Jullian you touched a little bit on
So that kind of wraps it all up nice. So we have to talk about stellar chemical compositions. And for reference here I have at the top the composition of the universe after the Big Bang.
Let's get to the heart of the matter. So my work is often called stellar archaeology because we take these survivor stars that are in the Milky Way today, and we study their chemical composition so that we can their age, or at least their formation era, due to the small amounts of heavy elements in them.
And each dark line refers to a little piece of light that is lost. And what's happening in the stellar surface that we are all observing, there are all sorts of elements, atoms, swirling around. And each element absorbs at certain wavelengths.
It just depends how thick the clouds are whether you keep observing through the clouds or you have to stop because there's just nothing coming Whatever we find in the stellar surface today came from the birth gas cloud from which the star formed, which means it must have come from that previous generation
It just depends how thick the clouds are whether you keep observing through the clouds or you have to stop because there's just nothing coming It's absolutely a selection bias because stellar mass correlates inversely with lifetime.

variety of means, physical means, those particles. You push them together. The most common is called laser inertial fusion. grad student does the math on a stellarator and says, "This is all I need to do. I just need to make a magnetic coil in this very
Usually, for a stellar mass black hole, we think it's microseconds.
This is a more spherical region of chaotic stellar motion.
She's President and Chief Storytelling Officer at Stellar Collective, a consulting firm focused on strategic storytelling.
We now know of all of these masses in the stellar graveyard from detections by LIGO and Virgo.
You have to find a use for yourself. And the only thing I really had to research was specific stellar systems.
Thank you so much for coming today. And he did it for two years and got stellar marks.
And this will also, I think, give you an idea of some regularities that we're learning about how galaxies work. So one is, the stellar mass to halo mass ratio as a function of halo mass. The Milky Way is about a 10 to the 12 solar mass object.
And again, the dark matter and stars are very aligned, and they're elongated. On the left-hand side of this diagram the stellar mass is less than the dark matter mass in the center of the galaxy. On the right-hand side the stellar mass is the dominant part, the more star-dominated.
And a lot of what they were looking at were stellar positions.
