But you have these two centrosomes, and they facilitate the development of these microtubules, which are

The centrosomes are these structures that help direct what happens to these microtubules.

So let me just draw this.

So why might it be hard to find?

So, I choose mine as 10 nano grams per mL.

Feynman said, Forget all of that.

It doesn't change it quite enough, but that protein acts just a little bit different.

What does that mean?

Take a look at this little tuft of capillaries.

Look at this hole in the middle.

They're basaltic lava flows, and that's what this sand looks like, very similar to the sand that you would see in Haleakala.

It is able to couple onto the growing and shrinking microtubules.

Well, it's probably microscopic, and it's never easy to study microscopic things, although the amazing tools that we now have to do that allow us to study things in much greater depth, at much smaller scales than ever before.

And I present to you a concept that these are extended neurological membranes.

And you can see those in micrometeorites.

The syndrome, the female pattern now is called microvascular coronary dysfunction, or obstruction.

What does a differential mean?

So this starts to actually dissolve and disassemble, and then these things start to grow and attach themselves to the centromere.

And you'll see, there's this one little last bit that's still remaining red.

It's actually fascinating.

A smiling, happy little boy, holding a new pet... and begging me to let him keep it.

So at the same time that in telophase II these get pulled part, you have the cytokinesis.

A differential is a really, really, really, really infinitely small difference.

And these things have kind of spread apart, these microtubules, so they're doing two functions, really.

In fact, outer space is filled with sand, and that sand comes together to make our planets and the Moon.

That hole was caused by a micrometeorite hitting the Moon.

So these guys are now at the left end of the cell and these guys are now at the right end of the cell.

At this point, they're kind of pushing these two centrosomes apart.

If say, universe was populated by particles such as galaxies or alignment of a clouds, and we can count, then their number per unit volume is something that will be also dependent on the expansion rate.

Autopsy studies from people who died in car accidents have shown that about 40 percent of women between the ages of 40 and 50 actually have microscopic cancers in their breasts.

You just open it, twist leaves, and you see a whole new world of minute insects, or little spiders of one millimeter, one and a half, two millimeters long, and you can distinguish between the good ones and the bad ones.

So you know suppose this is your initial value of theta one over here and it's already at a local optimum or the local minimum.

(Singing)

These things get pulled apart by the kinetochore microtubules, while the other microtubules keep growing and push and these two things further apart.

The bottom of it is carved from a grain of sand, because I wanted to get a bit of the stone effect.

And then one of the other longer is getting pulled in that direction, and it's all by these microtubules connected at the kinetochore structures by a centrosome as kind of the coordinating body.

So I have my magenta one here, I have my magenta one here, and I have my other one here, my green one there, and, of course, you have your centrosomes, the microspindles that are coming off of them.

And if you look carefully, you can see that there's a black blush right there.

A differential just means an infinitely small change in y, in this case, so that's a differential in y, or an infinitely small change in x.

Differentiation

I go into the other room and read.

The little girl never smiles at anyone other than Emily.

And every time they do that, they get a tiny little packet of energy.

About 50 percent of men in their 50s and 60s have microscopic prostate cancers, and virtually 100 percent of us, by the time we reach our 70s, will have microscopic cancers growing in our thyroid.
