Quotes About Molecules

The one thing the Universe has in excess and is apparent in every molecule of air ever breathed and every atom of every object is potential.

My aging body transmits an ageless life stream. Molecular and atomic replacement change life's composition. Molecules take part in structure and in training, countless trillions of them. After my death, the molecules of my being will return to the earth and sky. They came from the stars. I am of the stars.

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.

The atoms may be compared to the letters of the alphabet, which can be put together into innumerable ways to form words. So the atoms are combined in equal variety to form what are called molecules.

What I want to do is demonstrate that biology can learn how to make a vast array of molecules that people thought were outside the realm of biology.

We know what molecules are needed to sense light - what turns that signal that detects light into an electrical signal. We know how smells are detected. But we have a vast number of senses for which we know what the signal is, but we don't know what the receiver is.

I tell my students to try to know molecules, so well that when they have some question involving molecules, they can ask themselves, What would I do if I were that molecule?

For polyatomic free radicals and ions, one is dependent both for the ground states and the excited states on the study of electronic spectra to obtain the shapes and the geometrical parameters.

Studying organisms at a molecular level was totally compelling because it was moving from being a naturalist, which was the 19th-century kind of science, to being very focused and really getting to the heart of these molecules.

The reactions of organic magnesium compounds are of two kinds - reactions of substitution and reactions of addition.

The kinks created by cis- double bonds in fatty acids make them difficult to align. Therefore UFAs aggregate poorly, and melt at lower temperatures

A change as small as the position of a bond—the link between atoms in a molecule—can lead to enormous differences in properties of a substance and in turn influence the course of history. So this book is not about the history of chemistry; rather it is about chemistry in history.

She'd hardly been aware of feeling anxious, but that was because anxiety was everywhere, built into the very molecules of the world, or so it had seemed.

one of the first assemblies of smart molecules had been the crew of that ingenious unit called the gene.† An even grander molecular fusion had been the chromosome—a knottily twisted rope of genes which not only worked together,* but fused so tightly that they formed a massive mega-molecule.

you must have carbon.23  Arsenic, boron, and silicon are the only other elements on which complex molecules can be based, but arsenic and boron are relatively rare and, where concentrated, poisonous to life, and silicon can hold together no more than about a hundred amino acids. Only carbon yields the chemical bonding stability and bonding complexity that life requires. Given the constraints of physics and chemistry, we now know that physical life must be carbon-based.

The sea is blue because the sunlight is reflected back to our eyes from the water molecules or from very minute particles suspended in the sea. In the journey of the light rays downward into the water and back to our eyes, all the red rays of the spectrum and most of the yellow have been absorbed, so it is chiefly the cool, blue light that we see.

Examples of such self-reorganization abound in Order Out of Chaos. Heat moving evenly through a liquid suddenly, at a certain threshold, converts into a convection current that radically reorganizes the liquid, and millions of molecules, as if on cue, suddenly form themselves into hexagonal cells.

Captain John Sheridan: I wish I had your faith in the universe. I just don't see it. Delenn: Then I will tell you a great secret, Captain. Perhaps the greatest of them all. The molecules of your body are the same molecules that make up this station , and the nebula outside, that burn inside the stars themselves. We are starstuff. We are the universe made manifest, trying to figure itself out. And as we have both learned, sometimes the universe requires a change of perspective.

It's all just chemicals.

we can hear music under water or in other fluids if the water (or other fluid) molecules are caused to vibrate. But in the vacuum of space, with no molecules to vibrate, there is no sound. (The next time you're watching Star Trek and hear the roar of the engines in space, you'll have some good Trekkie Trivia to share.)

All vinyl polymers may be regarded as built from monomeric units containing a tertiary carbon atom.

The broader appeal of statistics lay in the idea of an order beneath apparent randomness. Individuals—molecules or humans—might act unpredictably, but statistics seemed to show that in the aggregate their behavior conformed to stable laws.

One oxygen bonds with two hydrogen to form H2O

soap or detergent molecules forge a link between the oil and the water; one end of the soap or detergent molecule binds to the oil, the other to the water. When we rinse the fabric, the stain lifts from its surface.
