A Quote by Leroy Chiao

If you think about the energy that a rocket engine has to put out and all the fuel and you're sitting on top of like a bomb. And on the Space Shuttle, that big orange tank is filled with liquid hydrogen and liquid oxygen, the white cell rocket boosters on the sides are filled with solid propellant. There's a lot of energy in all those chemicals there and you've got to control it in a way so it doesn't explode. So, there's a lot of plumbing, a lot of valving, a lot of control systems, and it's a very complicated thing. So, how do you bring the price of that down?
A lot of the progress in machine learning - and this is an unpopular opinion in academia - is driven by an increase in both computing power and data. An analogy is to building a space rocket: You need a huge rocket engine, and you need a lot of fuel.
There was a lot of light and a lot of rumbling and vibration, especially the first minute or minute-and-a-half. And then after about two minutes, when the solid rocket boosters separated, the ride got a lot smoother.
Apart from the obvious advantages of having ice to melt, filter, then drink, you can also break apart the water's hydrogen from its oxygen. Use the hydrogen and some of the oxygen as active ingredients in rocket fuel and keep the rest of the oxygen for breathing. And in your spare time between space missions, you can always go ice skating on the frozen lake created with the extracted water.
Back in the 1950s, there was a top-secret program code-named SUNTAN being conducted at a top-secret facility called Skunk Works. Its objective? To develop a liquid-hydrogen-powered spy plane. Because liquid hydrogen is incredibly volatile, early experiments were conducted inside a bomb shelter with eight-foot-thick walls.
Anger is a fuel. You need fuel to launch a rocket. But if all you have is fuel without any complex internal mechanism directing it, you don't have a rocket. You have a bomb
When you are relaxed, you can focus a lot more easily than when you are hyper and over-energetic. It's important to be "up" for a competition, but you shouldn't have too much energy, because you might not be able to control it. In competitions, it is important to be able to bring the power and energy you are feeling down to a level that you can control. This comes with practice and experience.
I think a lot of people think I'm either unintelligent because I'm a very happy person and I have a lot of energy or that it's a fake happiness, like fake energy. I completely understand that because it's a lot to handle, and I am a very emotional human being.
I like big shows, a lot of volume and a lot of energy. I love electric instruments. But I do love mixing those with bluegrass instruments and cranking those up, too, with a little bit of that rock energy.
I'm a complete control freak. We worked a lot on the pace and where to put the silences. We choreographed the gestures and movements. We had a lot of rehearsals and a lot of takes. Also, there's something special that comes out of those two actors: he's water and she's fire.
As we explore ways to bring price relief and bolster our country's energy independence, one significant energy source has emerged as a potential solution, hydrogen fuel cells.
All too often we're filled with negative and limiting beliefs. We're filled with doubt. We're filled with guilt or with a sense of unworthiness. We have a lot of assumptions about the way the world is that are actually wrong.
Without a drummer, you've got that sort of running, chicken-chasing, rhythmic thing happening with the banjo in the top end - it's what gives our music a lot of its momentum, a lot of its energy.
I spent a lot of time, a lot of energy trying to be a better artist and I still [do]. I spend a lot of time focusing on my craft. If you're going to take your passion into something beyond just something for fun on the side, you got to spend a lot of time on it to be great, and then you've got to make smart decisions about who you collaborate with [and] where you live [to] put yourself in the right situations to meet the right people to catch those breaks.
I think about death a lot, like I think we all do. I don't think of suicide as an option, but as fun. It's an interesting idea that you can control how you go. It's this thing that's looming, and you can control it.
The expense of getting into space is the rocket launch, the rocket itself. Rocket's right now, commercial rockets cost probably somewhere between $50, or $120, or $150 million per launch. And those are all expendable. That is, you've got to buy a new rocket for each launch. So, that really is the critical part. If there was some kind of really, a revolutionary breakthrough and the price of rockets fell by an order of magnitude, I mean, just imagine what that would do as far as getting access to more ordinary people.
Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.
