It had some strings and pulleys and some springs.

And all of these are the same principles that apply to the saddle shaped spring in stomatopods.

So we thought, OK, this must be a spring the saddle could very well be a spring.

It has six legs there are the tuned, springy legs.

And they can be modeled by a spring mass system that we call the spring mass system because we're biomechanists. It's actually a pogo stick.

So, the saddles that saddle shaped spring has actually been well known to biologists for a long time, not as a spring but as a visual signal.

Now, what good are springy legs then? What can they do?

We want to fold up the legs and shoot it up for long range motion.

So, we've had very solid evidence showing that that saddle shaped structure actually compresses and extends, and does, in fact, function as a spring.

There needs to be some kind of spring loaded mechanism in order to generate the amount of force that we observe, and the speed that we observe, and the output of the system.

So, very interesting parallels between the biological and the engineering worlds. And interestingly, this turns out the stomatopod saddle turns out to be the first described biological hyperbolic paraboloid spring.

And then we did a series of calculations, and what we were able to show is that these mantis shrimp have to have a spring.

So sort of an interesting strange fact to find a visual structure right in the middle of their spring.

And again, that brings us back to the importance of that spring in storing up and releasing so much energy in this system.

Same principle it only has six moving parts, six motors, but it has springy, tuned legs. It moves in the gait of the insect.

And these animals may very well be making use of not only the force and the energy stored with that specialized spring, but the extremes of the fluid dynamics. And they might actually be making use of fluid dynamics as a second force for breaking the snail.

And this is quite interesting, to find evolutionary origins of visual signals on what's really, in all species, their spring.

The animals, when you look at them running, appear to be self stabilizing like this, using basically springy legs. That is, the legs can do computations on their own the control algorithms, in a sense, are embedded in the form of the animal itself.

It's a piece of cake.

I haven't had time to do the dishes for two days they are in a pile in the kitchen sink.

The ATA is the first telescope built from a large number of small dishes, and hooked together with computers.

Have you ever seen a UFO?

Scratch and mix audio

In fact, it's peanuts.

We couldn't believe that it could do this. It said to us that if you could build a robot with very simple, springy legs, you could make it as maneuverable as any that's ever been built.

Here it is This Island Earth.

She gave me this compact disc.

What we discovered is whether you look at the leg of a human like Richard, or a cockroach, or a crab, or a kangaroo, the relative leg stiffness of that spring is the same for everything we've seen so far.

I must take my oboe for repair.

Learn the piano just by playing a game

Save it on the external hard drive.

I listened to some CDs last night.

He saw a UFO flying last night.

So it would be able to replicate the information that is on the DVD.

There were pigeons roosting in the dish.

Now, I said all these animals are sort of working like pogo sticks they're bouncing along as they move. And you can see that in this ghost crab, from the beaches of Panama and North Carolina.

We have to go a little beyond that. Now let me explain why vibrational theory has some sort of interest in it. These molecules, as you saw in the beginning, the building blocks had springs connecting them to each other.

After decades indeed, centuries of employing such tricks, physicists have forgotten that they are modeling phenomena, not necessarily uncovering Divine Truth. For instance, we can easily write down the equations for a ball on a swinging spring, but if we stretch the spring enough and swing the ball hard enough, we can t solve those equations.

The inclusion of some form of self destruct system built into a sub munition so that they will function after a defined short time period after impact would substantially reducing the dudding rate.

Well the same plate shows up a whole bunch of times.

Keiko deftly piles up the dishes and takes them to the sink.

And if I take a reed if I rub this, something very amazing happens.

It's actually not very hard. Ninety eight percent of cases, this is a piece of cake.

Finally, I have a thing for the keys on a flute or a clarinet.

They don't give you five options on the reduction, right?
