So everyone has that problem, models have that problem, too.
I came to a happy Jewish family in dark days in Europe.
Knowing without seeing is at the heart of chemistry.
A few atoms added here, subtracted there, is all it takes to make the difference between male and female sex characteristics, between a harmless molecule and a deadly addictive one.
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.
From a chemist's point of view, the surface or interior of a star…is boring—there are no molecules there.
Alan Rocke's Image and Reality does so many things vividly and convincingly: it shows how visual images led chemistry step by step to the reality of the microscopic world; how simple portrayals of the logic of substitution and combination were reified; brings to our attention the imaginative, neglected work of Williamson and Kopp; and takes a critical look at Kekule's daydream. And it beautifully delineates the essential place the imagination has in science. A rewarding, lively picture of chemistry in formation.
Whatever it takes, prove to yourself right now, that you deserve the wildest of dreams that you could ever imagine. BUT. . . . . . . . . . . Only if you are willing to bleed, sweat and work for it.
It was long after midnight and the stars looked damp and chilly; the air was full of the busy silence of the night, which is created by hundreds of small furry things treading very carefully in the hope of finding dinner while avoiding being the main course.
In the case of pilots, it is a little touch of madness that drive us to go beyond all known bounds. Any search into the unknown is an incomparable exploitation of oneself.
I don't think that mass drug taking is a good idea. But I think that we must have a deputized minority, a shamanic professional class if you will, whose job is to bring ideas out of the deep black water and show them off to the rest of us and perform for our culture some of the cultural functions that shaman perform in pre-literate cultures.
