into some hidden worlds inside your own body

These microscopes use a beam of electrons

to be seen by the photons of visible light.

if you mentally divide one tiny millimeter

So, let's start with something on the body

that we can measure at about 100 microns wide,

which now you can see is covered with scales,

that are being secreted into a storage chamber

Electron images only happen in black and white.

I often colorize my images for various reasons,

when I photographed them in the microscope.

And the heart muscle has this curious structure

that's kind of like corrugated cardboard.

That's what allows the heart to expand and contract as it's beating.

Well, we all know to stay away from asbestos

and now you can see that it's composed of

Each one of those needles is a single crystal.

And in this picture, they're begininng to pry apart

What else might we want to avoid breathing?

We're looking here at the particles of diesel soot,

In fact, each one of these little particles

of nice, fat, happy, healthy red blood cells,

but they're all tangled up in a network of fibers.

And so, it surrounds a group of red blood cells

and beginning to grow what's going to become spikes.

which you can see is covered with bacteria,

to about 1,000 different species of bacteria.

or the internal surfaces of the teeth themselves.

and I want to call your attention to the little holes.
