Now I'm a scientific expert; that means I know nothing about absolutely everything.
Interpretation
This quote humorously highlights the vastness of knowledge and the limits of individual expertise.
Arthur C. Clarke's quote suggests that while one may achieve a level of expertise in a particular scientific field, it simultaneously highlights the immense amount of knowledge that remains unknown. The irony in stating one is a 'scientific expert' while knowing 'nothing about absolutely everything' underscores the humility required in the pursuit of knowledge.
In practice
In a lecture about the importance of continuous learning, this quote can demonstrate the paradox of knowledge.
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.

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 we are serious about moving toward energy independence in a cost-effective way, we should invest in solar energy. If we are serious about cutting air and water pollution and reducing greenhouse gas emissions, we should invest in solar energy.
The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species.
The opinion prevailed among advanced minds that it was time that belief should be replaced increasingly by knowledge; belief that did not itself rest on knowledge was superstition, and as such had to be opposed.
While I thought myself employed only in forming a nomenclature, and while I proposed to myself nothing more than to improve the chemical language, my work transformed itself by degrees, without my being able to prevent it, into a treatise upon the Elements of Chemistry.
If everything in the universe depends upon everything else in a fundamental way, it might be impossible to get close to a full solution by investigating parts of the problem in isolation.
I tried out various experiments described in treatises on physics and chemistry, and the results were sometimes unexpected. At times, I would be encouraged by a little unhoped-for success; at others, I would be in the deepest despair because of accidents and failures resulting from my inexperience.
