Molecular Dynamics Quotes

On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer speeds.

All theoretical chemistry is really physics; and all theoretical chemists know it.

On my return to Pittsburgh, I resolved to go back to the fundamental problems of electronic structure that I had contemplated abstractly many years earlier.

Who then can calculate the path of the molecule? how do we know that the creations of worlds are not determined by the fall of grains of sand?

Life is a relationship among molecules and not a property of any molecule.

Not every collision, not every punctilious trajectory by which billiard-ball complexes arrive at their calculable meeting places lead to reaction. ... Men (and women) are not as different from molecules as they think.

In the process of making nanomaterials, we learned that with the electronic density of states, the phonon electronic properties and everything change at the nano-level. So the thermoelectric properties would also be changed.

Much of my work in biology has been driven by my early training in chemistry. When studying a new chemical compound, the first and most important thing is to determine its detailed molecular structure.

My laboratory uses evolution to design new enzymes. No one really knows how to design them - they are tremendously complicated. But we are learning how to use evolution to make new ones, just as nature does.

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.

Our brains have evolved to help us survive within the orders of magnitude of size and speed which our bodies operate at. We never evolved to navigate in the world of atoms.

No lens is quick enough to track the movement of the human body. The molecules are always moving.

As soon as we step beyond the established boundaries of pure thermodynamic theory, we enter a trackless region confronting us with obstacles which even the most astute of us are almost at a loss to tackle.

The theoretical side of physical chemistry is and will probably remain the dominant one; it is by this peculiarity that it has exerted such a great influence upon the neighboring sciences, pure and applied, and on this ground physical chemistry may be regarded as an excellent school of exact reasoning for all students of the natural sciences.

In a gas, motion has the upper hand; the atoms are moving so fast that they have no time to enter into any sort of combination with each other: occasionally, atom must meet atom and, so to speak, each hold out vain hands to the other, but the pace is too great and, in a moment, they are far away from each other again.

When I began playing around at being a physical chemist, I enjoyed very much doing work on the structure of DNA molecules, something which I would never have dreamed of doing before I started.

Molecular collision dynamics has been a wonderful area of research for all practitioners. This is especially true for those who were following the footsteps of pioneers and leaders of the field twenty years ago.

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

When I started engineering proteins I didn't know how hard it would be.

I have lived much of my life among molecules. They are good company. 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? I tell them, Try to feel like a molecule; and if you work hard, who knows? Some day you may get to feel like a big molecule!

A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.

It does not seem, however, that organic chemists were much worried about barriers to rotation in organic molecules in general at that time because there was no technique available to demonstrate the phenomenon experimentally.

It seemed, indeed, that the study of light-scattering might carry one into the deepest problems of physics and chemistry, and it was this belief which led to the subject becoming the main theme of our activities at Calcutta from that time onwards.

But the nature of my main work in chemistry can be better represented by more than 280 English publications, of which roughly 200 concern the theory of chemical reactions and related subjects.

The visible and near-ultraviolet emission spectrum of the CH radical has been known ever since spectra of an ordinary Bunsen burner have been taken.
