Chemical reactions involve change on two levels

KS Now the way it works there's a matrix of color dyes.

We created the responsive room where the lights, music and blinds adjusted to your state.

And the deeper the level at which they change the pattern, the more lasting the change is.

We're from Ghana and we play for change

I am the perceiver of thoughts, of emotion, of time, of actions, of reactions, of interactions, of change, of hope.

In order to facilitate this improved dance date getting process,

Explosions are the result of chemical reactions happening almost instantaneously.

The nitrogen in the atmosphere.

It represents the change in a reliable way of the responses of tens of millions, possibly hundreds of millions of neurons in your brain.

When you're studying chemistry, you'll often see reactions.

But the way we react to different combinations of these phenomena is complex and emotional and not totally understood.

We can't.

We don't have a minute... Let's think about that for 10 seconds.

Rather than revolution, we're much more interested in evolution, this idea that things gradually evolve by adapting and improvising to the changes of the world.

The building is equipped for change.

What I could do is I could put an antibody in this network such that would react specifically to the mesothelin.

No reaction.

It's responding well to signal, right?

What they don't go back and get, those seeds become whitebark.

I watch faces.

The young adapt to change easily.

During a chemical reaction mass is neither lost nor gained. The sum mass of the material going into the reaction equals the sum of the mass of the products of the reaction.

But of course, life is more than just exotic chemistry.

Uncertainty is what makes play fun.

Sensors don't respond.

And the battery runs on a... a chemical reaction.

I could put it in this network of carbon nanotubes such that it would react only to the specific protein biomarker, but also what I would do is I changes its electrical properties based on the amount of the protein present, so much that I can measure it with the 50 dollar ohmmeter that I got from Home Depot.

It's not responding, sir.

When acid comes in contact with metal, it causes a chemical reaction.

People fear change. It's normal.

We also have been working with some scientists and engineers from UPenn to come up with a chemically actuated version of this amoeba robot.

One of the materials that can do this is a remarkable material, carbon, that has changed its form in this incredibly beautiful reaction where graphite is blasted by a vapor, and when the vaporized carbon condenses, it condenses back into a different form chickenwire rolled up.

Then their other attribute is that they have this great chemistry.

It sends equipment, men to Mali

But what a catalyst is is something that doesn't change.

We, you, are all starving your cells.

Meet our chemist, Harriet.

So they get immune to sounds that scare them after awhile.

The body quickly adjusts itself to changes in temperature.

No, skipper. This thing runs counter to every known law of adaptive evolution.

The smaller the ice mass, the faster it responds to climate.

They live in the ice. Generate heat through a chemical reaction.
