In October of 1903, the prevailing opinion of expert aerodynamicists was that maybe in 10 million years we could build an aircraft that would fly.

We can do it because in space there are no aerodynamics.

In 2004, Sauber spent a large sum of money on a new wind tunnel at Hinwil, and a high performance supercomputer (called Albert ) to help refine the aerodynamics of their cars.

And these are called alveoli.

A significant part of aeronautical science is a branch of dynamics called aerodynamics, which deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft.

Windmills?

And then you have a bronchiole that's terminating in that air sac.

But the oxygen will come through our larynx, into our trachea, through the bronchi, eventually in bronchioles, ending up in alveoli and being able to be absorbed into what where the arteries, but then we're going to go back and then essentially oxygenate the blood.

It enters our body through the nose and mouth, moves down into the pharynx, trachea and bronchial tubes, and ultimately reaches the alveoli air sacs in the lungs.

It was called it was called The Air Pump, or something like The Leviathan and The Air Pump.

No, agile aerial robots like this one.

(Laughter) No, agile aerial robots like this one.

Let me draw these air sacs.

WK Yeah. The windmill.

Do you have the air cushion?

Trapeze is always good business.

And lastly, to the slightly obscure world of entropy the second law of thermodynamics.

Maybe a bronchiole is terminating in another air sac just like that another set of air sacs just like that.

The girl is checking out the rear of the bicycle.

Syrian ships and aircraft

Here it is, it's about bicycle accidents.

Okay, deploy the airbags. Open.

And when I'm on my bike,

By decreasing the surface area of the airways, you're increasing the pressure of oxygen moving from the alveoli to the blood.

So what's going to happen is that the air is flowing through the bronchioles and circulating around the alveoli, filling the alveoli and as they fill the alveoli, the little molecules of oxygen are allowed to cross the membrane of the alveoli and essentially be absorbed into the blood.

And you didn't know about the windmill, you know?

This is called a cycle valve tube.

which are like the airwaves, if you will

And if you remember from the last video, these are kind of where air goes in through our trachea, then that splits up into our bronchi, and then those split into the bronchioles, and the bronchioles terminate at these alveoli.

Here he worked on thermodynamics and statistical mechanics, bringing a new approach to physical chemistry.

Upon this she returned to Iran and became Assistant Professor in thermodynamics at University of Tehran.

You can measure the aerodynamic forces it's creating.

These epiphytes are mainly dominated by the mosses.

Must have been some bicycle trick

It's susceptible to motion by the air currents.

American. A great flier. You know, the trapeze.

Have you ever noticed that it's harder to start pedaling your bicycle than it is to ride at a constant speed?

There are no effective therapies for viral bronchitis.

And when the bronchi no longer have cartilage around them, they're no longer rigid.

Also, we see how we measure the aerodynamic efficiency.

Let me draw one right here.

Please forget it, what happened up on the ferris wheel.

Entropy, based on the 2nd law of thermodynamics, holds that states of disorder tend to increase.
