In the middle we have a motor, and we also have a gear in it, and we use the gear to transfer the circulation of the motor.

So, that's a finished gear.

Every one of these circles is a cog, a stack of cogs, and this thing is as big as a steam locomotive.

And the gears work in water as well.

So let's talk about the memory. The memory is very like the memory of a computer today, except it was all made out of metal, stacks and stacks of cogs, 30 cogs high.

So, we have a motor here on the left, and it goes through a gear train.

ES Well, imagine that you have two gears of a watch, a big one and a small one.

You can do gears and nuts and bolts that you can buy at Whole Foods.

After many years of bending gears with a pair of pliers, I made that tool, and then I made this other tool for sort of centering gears very quickly sort of developing my own little world of technology.

That little gear there switches back and forth to change direction.

So starting from a three dimensional ping sound system, a vibrating vest, a click wheel with voice commands, a leg strip, even a shoe that applies pressure to the foot.

So this is just three sets of cogs, and it's going to add. This is the adding mechanism in action, so you imagine this gigantic machine.

Scanning teeth today, you can have your teeth scanned and dental coatings made in this way to fit you.

There are 12 pairs of 50 1 reductions, so that means that the final speed of that gear on the end is so slow that it would take two trillion years to turn once.

Their entire camp, every item of gear, was ferried 885 miles from McMurdo Station, the main U.S. supply base on the coast of Antarctica.

Typical rod products are reinforcing rods for concrete, engineering products, gears, tools and a range of products used in building construction.

It's a big tooth.

Harvest baby teeth.

You re grow a set of teeth.

His proposal is not worth talking about.

So when you measure those teeth, it was clear that she started out to be a girl with very small canine teeth.

It has a big serration on the edge.

We can make a chicken with teeth.

His teeth are yellow from smoking too much.

The teeth on this fish are so long that if they closed inside the mouth of the fish, it would actually impale its own brain.

A fellow by the name of Matthew Harris at the University of Wisconsin in Madison actually figured out a way to stimulate the gene for teeth, and so was able to actually turn the tooth gene on and produce teeth in chickens.

It does it, it turns out, with the same denticles that you had on Speedo bathing suits, that broke all those records in the Olympics, but it's a particular kind of pattern.

It does have big teeth, however, and it's kind of hard to convince people if an animal has big teeth, that it's a harmless creature.

So many people lost their teeth that dead people s teeth were recycled. The teeth of the 50,000 soldiers killed at Waterloo in 1815 were extracted and used until the 1860s as replacements for the toothless.

Bear in mind, there are no nerves in the teeth.

This is a chicken with teeth.

Dolphins and toothed whales use echolocation.

I had my teeth examined at the dentist's.

Dentists take x rays to examine your teeth.

His teeth are white like a pearl.

But to do that, you need the permanent dentition, which you don't see here, because what you have here are the baby teeth.

Their teeth are basically bashed out with a metal rod.

They showed puss oozing out from between their teeth.

I mean, you're born with no teeth.

You give away all your teeth to the tooth fairy.

I want you to inspect its mouth, look at its teeth.

And then when you look at this, you say, That's a tooth.

You can see the eye socket and you can see the little teeth in the front.

My teeth aren't as white as I'd like them to be.

You see, this is what India is today. The ground reality is based on a cyclical world view.
