... chemistry is a trade for people without enough imagination to be physicists.
Interpretation
The quote critiques chemistry as being less imaginative than physics.
Arthur C. Clarke humorously suggests that chemistry is seen as a less creative discipline compared to physics, implying that those who choose chemistry may lack the imaginative capabilities required to pursue the more abstract and theoretical aspects of physics. This statement underscores the perceived hierarchy in scientific fields based on creativity and innovation.
In practice
In a discussion about the differences between scientific disciplines, this quote can illustrate cultural perceptions of creativity in science.
Nowhere in space will we rest our eyes upon the familiar shapes of trees and plants, or any of the animals that share our world. Whatsoever life we meet will be as strange and alien as the nightmare creatures of the ocean abyss, or of the insect empire whose horrors are normally hidden from us by their microscopic scale.
As our own species is in the process of proving, one cannot have superior science and inferior morals. The combination is unstable and self-destroying.
It has yet to be proven that intelligence has any survival value.
The best measure of a man's honesty isn't his income tax return. It's the zero adjust on his bathroom scale.
It was the mark of a barbarian to destroy something one could not understand.
My favorite definition of an intellectual: 'Someone who has been educated beyond his/her intelligence'.
If there is a small rocket on top of a big one, and if the big one is jettisoned and the small one is ignited, then their speeds are added.
Science appears to us with a very different aspect after we have found out that it is not in lecture rooms only, and by means of the electric light projected on a screen, that we may witness physical phenomena, but that we may find illustrations of the highest doctrines of science in games and gymnastics, in travelling by land and by water, in storms of the air and of the sea, and wherever there is matter in motion.
The problem [with genetic research] is, we're just starting down this path, feeling our way in the dark. We have a small lantern in the form of a gene, but the lantern doesn't penetrate more than a couple of hundred feet. We don't know whether we're going to encounter chasms, rock walls or mountain ranges along the way. We don't even know how long the path is.
Interestingly enough, not all feelings result from the body's reaction to external stimuli. Sometimes changes are purely simulated in the brain maps.
First, it is necessary to study the facts, to multiply the number of observations, and then later to search for formulas that connect them so as thus to discern the particular laws governing a certain class of phenomena. In general, it is not until after these particular laws have been established that one can expect to discover and articulate the more general laws that complete theories by bringing a multitude of apparently very diverse phenomena together under a single governing principle.
There is enough information capacity in a single human cell to store the Encyclopedia Britannica, all 30 volumes of it, three or four times over.
