... 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.

My favorite definition of an intellectual: 'Someone who has been educated beyond his/her intelligence'.
What, then, is this blue sky, which certainly does exist, and which veils from us the stars during the day?
Even those who do not, or cannot, avail themselves of a scientific education, choose to benefit from the technology that is made possible by the scientific education of others.
It's not going to be just humans colonizing space, it's going to be life moving out from the Earth, moving it into its kingdom. And the kingdom of life, of course, is going to be the universe.
Now is not the time to gut these job-creating investments in science and innovation. Now is the time to reach a level of research and development not seen since the height of the Space Race.
Any important disease whose causality is murky, and for which treatment is ineffectual, tends to be awash in significance.
If I could explain it to the average person, it wouldn't have been worth the Nobel Prize.
