At Mach 20, we can fly from New York to Long Beach in 11 minutes and 20 seconds.

That's still true today.

Six of eight Atlas rockets blew up on the pad.

We call it rocketcam.

40 years later, aero experts coined the term transonic.

Light travels faster than sound.

The speed of light is much greater than that of sound.

You see, they were having trouble in this flight regime, and it wasn't at all clear that we could fly faster than the speed of sound.

The new airplane flies at twice the speed of sound.

Activity Transition

Only 60 years later, it travels at 80 percent of the speed of sound, and we don't travel any faster today because commercial supersonic air travel turned out to be a bust.

It's a demotion.

Today, we don't talk about flying transonically, or even supersonically, we talk about flying hypersonically not Mach 2 or Mach 3, Mach 20.

The airplane is capable of supersonic speeds.

You know, sometimes you'd rather just speak your search query or ask a question.

But meanwhile, let's measure the speed of sound!

You drove rocket sleds at the speed of sound.

That would be a bad day, you know, if that happened, so we have to test, because we are deploying this parachute at supersonic speeds.

This jet travels about three times as fast as the speed of sound.

Burning the parachute as it fell.

This is a demotion, huge demotion

And that constant is the speed of sound.

Now I was known as here's a woman that's not going to listen.

Mathematicians have used photos to look at where in the twists and turns of a whip the crack sound comes when the whip is breaking the sound barrier.

What that means is they're both explosions in lay terms but a deflagration is where the wave, the shock wave travels at the speed of sound.

But this is what it looks like from the third stage of the rocket

The airplane is capable of supersonic speeds.

Then I tried typing words on my laptop and using its built in voice.

(music) (music)

You see, they were having trouble in this flight regime, and it wasn't at all clear that we could fly faster than the speed of sound.

Selects the color of the transition elements

Right in state 1 there are 2 ways to go on a.

35 years of designing supersonic aircraft for the military.

We go here, and then there's no way to ever get back down or get to 6, so we don't want to go to 4.

It is 'music with her silver sound' because musicians have no gold for sounding

The last one is analogous.

The initial state, if known, is ignored.

I could've used you, Stan.

But light was too fast for Galileo.

T of S, A, S for the transition function.
