Oh, that's a microscope.

We have a microscope.

Putting everyone in law enforcement under a microscope.

Sometimes they send you pictures of them using the microscope.

This is the way a living cell looks down a light microscope.

And these are actually microscopic you need a microscope to see these.

This could be an ant farm. This could be a microscope or anything.

looked at it under the microscope, you plated the culture, you injected the antiserum.

But look what the stamen and the pistil look like in a microscope. That's the stamen.

We couldn't have a germ theory of disease before we invented the microscope to see them.

The first time I looked in a microscope, I knew I wanted to be a doctor.

They post projects, so they say, I want to teach Huckleberry Finn to my class and we don't have the books, or I want a microscope to teach my students science and we don't have a microscope.

It's like building a microscope or telescope and revealing new structures about our own behavior around communication.

If you'd look closely under a microscope you'd see nerve endings at the outer layer of the vessel.

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

And that can be seen directly through a microscope, and I'm going to show you some of this today.

When I first saw living cells in a microscope, I was absolutely enthralled and amazed at what they looked like.

Today, you need to do a complicated laboratory procedure, create a bunch of microscope slides and have a trained person examine it.

And under the microscope, you can see hundreds of these brown stained blood vessels, capillaries that are feeding cancer cells, bringing oxygen and nutrients.

So when they were sitting in front of the microscope, when they were talking to their colleague at the water cooler, and all these things.

So these are nerves you see, down on the bottom, and the microscope probe that's being held by the robotic hand, up at the top.

So, there you see, it's a liver with colon cancer in it, and you see into the microscope a lymph node where cancer has invaded.

To look through a microscope at the galaxies that exist on the pinpoint of a human mind because that's the way my mom taught me.

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

I was out in the woods, hiking and taking samples frogs and snakes and bugs and pond water and bringing it back, looking at it under the microscope.

And you see that patient now six months after with an X ray showing you the regenerated tissue, which is fully regenerated when you analyze it under the microscope.

The real bacteria and viruses are so small we can't see them without a microscope, and you guys might know bacteria and viruses because they both make us sick.

They'd looked at dental calculus under a microscope, and what they had found was things like pollen and plant starches, and they'd found muscle cells from animal meats and bacteria.

Now, the way my microscopes work is, normally in a microscope you can see very little at one time, so what you have to do is you have to refocus the microscope, keep taking pictures, and then I have a computer program that puts all those pictures together into one picture so you can see actually what it looks like, and I do that in 3D.

Because if you look at a brain with your naked eye, you don't really see how complex it is, but when you use a microscope, finally the hidden complexity is revealed.

And so, I came to see these kinds of social networks as living things, as living things that we could put under a kind of microscope to study and analyze and understand.

And when we think about the classic image of the scientist in the lab, we have this image you know, they're pouring over the microscope, and they see something in the tissue sample.

What happened actually when Dunbar kind of looked at the tape is that, in fact, almost all of the important breakthrough ideas did not happen alone in the lab, in front of the microscope.

The normal cell, if you looked at it under the microscope, would have a nucleus sitting in the middle of the cell, which is nice and round and smooth in its boundaries and it looks kind of like that.

So I went ahead, collected wall tissue, prepared it so it was erect, sectioned it, put it on slides and then stuck it under the microscope to have a look, fully expecting to see crossed helices of collagen of some variety.
