Quotes About Nuclei

A]tomic nuclei are pretty hard to peer into. But that's not the root of the problem. It's that we simply can't, for quantum processes, talk about a historical progression of events that led to a given outcome. There's no story of how it 'got' to be that way.

13 "The Skylark of Space," Edward Elmer Smith, with Lee Hawkins Garby (uncredited) (The Buffalo Book Co., 1946); first serialized in Amazing Stories, 1928. 15 "this theory predicted results that were nonsensical": Quantum Physics of Atoms, Molecules, Solids, Nuclei, and Particles, Robert Eisberg and Robert Resnick (John Wiley and Sons, 1974). 16

Inside the "cells" there were no normal-looking organelles, no nuclei, endoplasmic reticulum, mitochondria, or Golgi bodies.

The doctors realized in retrospect that even though most of these dead had also suffered from burns and blast effects, they had absorbed enough radiation to kill them. The rays simply destroyed body cells - caused their nuclei to degenerate and broke their walls.

Once again the mastermind was Lionel Curtis, and the earlier Round Table Groups and Institutes of International Affairs were used as nuclei for the new network.

The nuclear force holds neutrons and protons together more tightly when they form iron nuclei than when they form any other kind of atomic nucleus.

White blood cells are the only fully functional cells in the circulation. Red blood cells have lost their nuclei by the time they enter the bloodstream, and platelets, which also lack a nucleus, are cell fragments that have split off a relatively large parent cell known as a megakaryocyte {mega, extremely large + karyon, kernel + -cyte, cell}.

All vertebrates except mammals have nuclei in their red blood cells.In mammals, these cells go through an extra stage of development in which the nucleus is discarded. The resulting cells are smaller, can flow through smaller capillaries, can be packed with more hemoglobin, and thus can carry oxygen and carbon dioxide more efficiently.

Of special note are certain divisional arrangements of main functions that are organized and coordinated by different brain components. For example, several nuclei in the brain stem, hypothalamus, and telencephalon are in charge of producing the behaviors to which I referred above, known as drives, motivations, and emotions with which the brain responds to a variety of internal and external conditions with preset programs of actions (e.g., secretion of certain molecules, actual movements

If constants like G and ? do not vary in time, then the standard history of our Universe has a simple broad-brush appearance. During the first 300,000 years the dominant energy in the Universe is radiation and the temperature is greater than 3000 degrees and too hot for any atoms or molecules to exist. The Universe is a huge soup of electrons, photons of light and nuclei.

Deep in the world of atomic nuclei, life is not always tranquil.

feel an emotion it is necessary but not sufficient that neural signals from viscera, from muscles and joints, and from neurotransmitter nuclei—all of which are activated during the process of emotion—reach certain subcortical nuclei and the cerebral cortex. Endocrine and other chemical signals also reach the central nervous system via the bloodstream among other routes.

If the strong nuclear force were slightly weaker, multi-proton nuclei would not hold together. Hydrogen would be the only element in the universe.

When a child comes in, I believe that it's a 'multipersonhood,' and it knows it, its consciousness knows it, and it has a nuclei in the center of its consciousness that is the repository of all experience and all knowledge. And when you look in the eyes of your baby and you feel this sense that they are an old soul, I believe indeed they are.

The research included neutron resonance spectroscopy, the angular distribution of pion elastic and inelastic scattering on nuclei with optical model fitting.

Parasitism and symbiosis were the true basis for evolutionary change. These processes lay at the heart of all evolution, and had been present from the very beginning. Lynn Margulis was famous for demonstrating that bacteria had originally developed nuclei by swallowing other bacteria.

Actually, dinosaur DNA is somewhat easier to extract by this process than mammalian DNA. The reason is that mammalian red cells have no nuclei, and thus no DNA in their red cells. To clone a mammal, you must find a white cell, which is much rarer than red cells. But dinosaurs had nucleated red cells, as do modern birds. It is one of the many indications we have that dinosaurs aren't really reptiles at all. They are big leathery birds.

Given the opportunity, under the right conditions, two cells from wildly different sources, a yeast cell, say, and a chicken erythrocyte, will touch, fuse, and the two nuclei will then fuse as well, and the new hybrid cell will now divide into monstrous progeny. Naked cells, lacking self-respect, do not seem to have any sense of self.

We still have not yet fully understood electrons and nuclei; for scientists, a speck of dust is very exciting. A particle of dust is a marvel.

Wellspring looked grave. "You realize that an entire future destiny might accrete around this momentary utterance? It's from just such nuclei of free will that the future grows, in smooth determinism.

Like so many named places in California it was less an identifiable city than a grouping of concepts--census tracts, special purpose bond-issue districts, shopping nuclei, all overlaid with access roads to its own freeway.

San Narciso lay further south, near L.A. Like many named places in California it was less an identifiable city than a grouping of concepts—census tracts, special purpose bond-issue districts, shopping nuclei, all overlaid with access roads to its own freeway.
