UV is bad for molecules because its high energy breaks the bonds between a molecule's constituent atoms. That's why UV is bad for you, too: it's always best to avoid things that decompose the molecules of your flesh.
Nanoengineering is learning how to make devices as small as 10 to 100 atoms in width. Much of the work is going on in the electronics industry, where there is great demand to pack more components onto computer chips.
Chemists have always been in the business of taking atoms and putting them together with other atoms with precisely defined connections.
Organic compounds exist in which a hydrogen atom, joined to the carbon, acquires acid properties as a result of the proximity of certain functional groupings.
If the Russians ever decide to atom bomb us, they're certain to drop an especially large one on the plant in Pleasantville.
The change from atoms to bits is irrevocable and unstoppable. Why now? Because the change is also exponential - small differences of yesterday can have suddenly shocking consequences tomorrow.
During the 20th century, we came to understand that the essence of all substances - their colour, texture, hardness and so forth - is set by their structure, on scales far smaller even than a microscope can see. Everything on Earth is made of atoms, which are, especially in living things, combined together in intricate molecular assemblages.
From the results so far obtained it is difficult to avoid the conclusion that the long-range atoms arising from collision of alpha particles with nitrogen are not nitrogen atoms but probably atoms of hydrogen, or atoms of mass 2. If this be the case, we must conclude that the nitrogen atom is disintegrated under the intense forces developed in a close collision with a swift alpha particle, and that the hydrogen atom which is liberated formed a constituent part of the nitrogen nucleus.
As science went further and further into the external world, they ended up inside the atom where to their surprise they saw consciousness staring them in the face!
The genius of Man in our time has gone into jet-propulsion, atom-splitting, penicillin-curing, etc. There is none over for works of imagination; of spiritual insight or mystical enlightenment. I asked for bread and was given a tranquilliser.
In case I conk out, this is provisionally what I have to do: I must clarify obscurities; I must make clearer definite ideas or dissociations. I must find a verbal formula to combat the rise of brutality--the principle of order versus the split atom.
One year, I'd completely lost my bearings trying to follow potty training instruction from a psychiatric expert. I was stuck on step on, which stated without an atom of irony: "Before you begin, remove all stubbornness from the child." . . . I knew it only could have been written by someone whose suit coat was still spotless at the end of the day, not someone who had any hands-on experience with an actual two-year-old.
Order can arise from chaos without anyone or anything directing the process when unstable combinations of atoms perish and others persist. In the 17th century, Descartes applied this insight to cosmology, and long before Darwin presented his more rigorous ideas about variation and selection, people began to speculate more openly about the origins of life and the species in Epicurean terms.
Leibniz accepted the argument that there must be indestructible simple entities if there is to be a complex world, but Epicurean morals and politics and anti-theology dismayed him. His 'monadology' which said that the true atoms of nature were unextended 'living mirrors,' was an imaginative and beautiful system, and even in many ways more modern than Epicurean atomism, than Epicurean atomism, but there was a reactionary aspect to it.
Man is made of the same atoms the world is, he shares the same impressions, predispositions, and destiny. When his mind is illuminated, when his heart is kind, he throws himself joyfully into the sublime order, and does, with knowledge, what the stones do by structure.
It seems to me that the modern painter cannot express this age, the airplane, the atom bomb, the radio, in the old forms of the Renaissance or of any other past culture. Each age find its own technique.
I think I've got 12... Superman, Batman, Wonder Woman, The Flash, Aquaman, Plastic-Man, Green Lantern, Sandman, The Justice League, The Atom Legion of Superheroes and Teen Titans.... Just about all of their top titles.
Like most young physicists, when I was a kid enraptured with physics, I thought, "Everything can be explained by the theory of the atom!" But as I've gotten older, and I look at the world, I think there's a lot of ways in which that kind of building up from the smallest building blocks doesn't actually account for the world. As I've gotten older, I've also become sensitive to the ways - to all that is not amenable to explanation. Things that, even if you had an explanation, what good would it be?
I'm found of what's called emergence - as the universe gets more complex, new laws can emerge. Like evolution - there's things that you just aren't able to explain, even if you had an understanding of atoms.
Idealism sees the world in God. It beholds the whole circle of persons and things, of actions and events, of country and religion,not as painfully accumulated, atom after atom, act after act, in an aged creeping Past, but as one vast picture, which God paints on the instant eternity, for the contemplation of the soul.
In 1958, I was a delegate to the Atoms for Peace conference in Geneva.
Carbon is, as may easily be shown and as I shall explain in greater detail later, tetrabasic or tetratomic, that is 1 atom of carbon = C = 12 is equivalent to 4 At.H.
The most fearful phenomenon of these midcentury years is not the atom bomb; atomic energy does have its constructive possibilities.... The most fearful event of these times is the colossal expansion of the government of the United States and the constant increase of executive power within the government.
I do not think myself to be a worm, and a grub, grass of the field fit only to be burned, a clod, a morsel of putrid atoms that should be thrown to the dungheap, ready for the nethermost pit. Nor if I did should I therefore expect to sit with Angels and Archangels.
Knowing he [Bob Serber] was going to the [first atom bomb] test, I asked him how he planned to deal with the danger of rattlesnakes. He said, 'I'll take along a bottle of whiskey.' … I ended by asking, 'What would you do about those possibilities [of what unknown phenomena might cause a nuclear explosion to propagate in the atmosphere]?' Bob replied, 'Take a second bottle of whiskey.'
