The question we ask is - if there is life on other planets, should we expect it to be based on the same molecules, i.e. be universal - or should we expect it to depend on the local conditions, i.e. on the planet's geochemistry. So to find out, we try experiments on biomolecules, starting with such geochemistry conditions.

Bulgarian Scientist

Richard Smalley

I know that, except for carbon, there would be no life in the universe. Except for this one atom, there would be no life. Well, why? When you think about it, it does get spooky. Encountering these molecules are spiritual experiences similar to what I remember in church as a child, only these are more serious.

American Scientist

William Lipscomb

The problem is how do molecules react. Because if you want to transform a molecule into something useful or something you're interested in, it helps a lot to understand the structure. That means you can explore much more complicated systems, much more complicated reactions.

Mike Myers

I love making stuff. There's a joy in having the first molecule of an idea, then testing it in front of audiences at secret shows that people only know about the day before. I videotape those, study them, enjoy being in the character and figuring out the movie.

Canadian Comedian

George M. Church

We went from a world where almost nobody knew anything about computers to a world where almost all of us are computer geeks for a huge fraction of our day. And I'd like to see that happen with the digital world of biological molecules, too.

William Henry Bragg

The infinite variety in the properties of the solid materials we find in the world is really the expression of the infinite variety of the ways in which the atoms and molecules can be tied together, and of the strength of those ties.

British Physicist

Akira Suzuki

Carbon-carbon bond formation reactions are important processes in chemistry because they provide key steps in building complex, bio-active molecules developed as medicines and agrochemicals.

Japanese Scientist

Pierre Teilhard de Chardin

There is neither spirit nor matter in the world. The stuff of the universe is spirit-matter. No other substance but this could have produced the human molecule.

French Philosopher

Tom Robbins

Our world isn't made of earth, air and water or even molecules and atoms; our world is made of language.

American Author

George Wald

I have lived much of my life among molecules. They are good company.

Defines a specific substance, with unique characteristics distinct from other materials.

Chemical Identity

Molecules are too small to be seen with the naked eye; scientific models represent them.

Not Visible

Knowing the word molecule is crucial when discussing science topics, especially in chemistry.

Essential Vocabulary

Atoms in a molecule are held together by chemical bonds, sharing or transferring electrons.

Atomic Bonds

In physics, mentioning a molecule usually means discussing its behavior or interactions.

Physics Context

Many diagrams or models exist to help visualize the structure and composition of molecules.

Scientific Illustrations

Used to stress how tiny an amount is; often in informal or hyperbolic speech.

Figurative Use

Emphasizes that something is incredibly small or insignificant in quantity or degree.

Emphasis on Size

Used outside of science to describe a negligible amount; not related to actual molecules.

Non-Scientific Context

 Medicine that slides down your throat can help treat a headache, a sore back, or a throbbing sprained ankle. But how does it get where it needs to go in the first place? The answer is that it hitches a ride in your circulatory blood stream, cycling through your body in a race to do its job before it's snared by organs and molecules designed to neutralize

How does your body...

 You might think that would happen at absolute zero, the coldest possible temperature. No one's ever managed to cool anything down that much, but even if we could, molecules would still move due to a quantum mechanical principle called zero-point energy. In other words, everything has been moving since the universe's very first moments,

The invisible motion of...

 that didn't violate the first law of thermodynamics, it still wouldn't work in the real world because of the second law. The second law of thermodynamics tells us that energy tends to spread out through processes like friction. Any real machine would have moving parts or interactions with air or liquid molecules

 On what? This isn't a new thought. Just a new way of seeing it. What if this is the way to prove the existence of molecules? Doesn't it sound like fun, dolly? You and me writing a paper that could change the world. And probability of chaos. Not the title I would choose, but we can discuss it.

Molecules Bumping Into...

 We already know that the world is made of things, things like cats and macaroni salad, and macaroni salad is made of things like mayo and mustard and celery, which are all made of molecules. As we'll see, these molecules are made of the same stuff, just mixed together in different ways.

The science of macaroni...

 and has the capacity manipulate matter with thousands of little drug molecules and thousands of little cells and nothing else but to me there is something more fundamental which is this idea that in our world we're stuck with two ways of making things there is the subtractive you can

 other, saw the same thing. My second instinct that kicked in quite quickly was, is the signal real? If it is, is it for sure phosphine or could there be another molecule mimicking it? And if it is real and it is phosphine, was I right in saying that only life could produce it?

Are There Aliens on...

 are hydrogen and oxygen atoms, and that's what water is. Of course we don't. We understand, very easily, very straightforwardly, that water is nothing more than the hydrogen and oxygen molecules suitably arranged. Everything else in the universe is the same.

Julian Baggini: Is there...

 Otherwise you'd be getting zapped all the time. Conductors like metals and salt water tend to have loosely bound outer electrons, which can easily flow between molecules. On the other hand, insulators like plastics, rubber and glass

 that cause neurons to fire more sluggishly and slow the release of important brain-signaling molecules. In other words, you get sleepy. Caffeine is what's called an adenosine receptor antagonist.
