People were dying by the droves of this disease.

These are somewhat arbitrary names that were assigned.

And remember that all our cereal crops are grasses as well.

Some of you may have seen some of these pictures before.

I've made telescopes,

And so previous studies had only focused on microscopy.

I've made microscopes,

The microbes that cover us.

How much is the microscope?

Hey, honey, how's that new microscope?

And so, we've known about this for some period of time.

Gibbs. Look in the microscope.

And that's what we get.

You can tell that from the little barbs on there.

The chromosomes, it would all be all over the place, and it actually would be very difficult to actually see it in a microscope.

This is a tumor dark, gray, ominous mass growing inside a brain.

Tom wants a microscope.

This is taken through a fiber optics microscope. It's down inside the nest.

And our anatomists are going to go in and take a deeper look at this.

Let me show you a video of what that does to the cell.

That's how small that is.

He looked at the slide under the microscope.

I won't do all of them.

That's how small it is.

So it probably even feels good for the insect, as well as looking good.

My foot is covering approximately 300 miles of mycelium.

Take a look at this little tuft of capillaries.

There's this incredible complexity in the CPU, and this incredible regularity in the memory.

We took our chip over to Hewlett Packard and used their atomic force microscope on one of these spots, and this is what you see you can actually see the strands of DNA lying flat on the glass here.

He was looking through a microscope.

And you can see in these central images here, scanning electron micrographs of some of these guys these are gardens of these bacteria.

I thought it looked kind of a little bit like the Moon, which is sort of interesting.

And so, when you start to look at emergent systems, you can look at a neuron under a microscope.

Do you know the difference between a microscope and a telescope?

So, when we look at cells, this is how we really got involved in biology and sciences, by looking at living cells in the microscope.

It's, of course, limited by science, by technology.

This microscope magnifies objects by 100 times.

Adjust the microscope's focus.

Set the focus of the microscope.

Adjust the focus of the microscope.

This is an inorganic tube.

I got one under the scope. You want to take a look?

I thought it looked kind of a little bit like the Moon, which is sort of interesting.

This is not an electron micrograph this is just a regular photomicrograph.

And, secondly, to convince you that every home really ought to have a scanning electron microscope.
