1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong. 2. The only way of discovering the limits of the possible is to venture a little way past them into the impossible. 3. Any sufficiently advanced technology is indistinguishable from magic.
Interpretation
The quote emphasizes the importance of pushing boundaries and recognizes that advanced technology can seem magical.
Arthur C. Clarke's quote reflects on the nature of scientific understanding and discovery. The first part suggests that respected scientists are likely accurate in their assessment of what is possible, but may misjudge what is impossible. The second part encourages exploration beyond current limits to uncover new possibilities, while the final statement highlights that as technology becomes more advanced, it can appear magical to those who do not understand it. Together, these thoughts inspire innovation and a willingness to challenge perceived limits in science and technology.
In practice
This quote can be used in a speech about the importance of scientific innovation.
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.

My favorite definition of an intellectual: 'Someone who has been educated beyond his/her intelligence'.
Science isn't just about solving this or that puzzle. It's about understanding how the world works: the whole world from the vastness of the cosmos to the particularity of an individual human life. It's worth thinking about how all the different ways we have to talk about the world manage to fit together.
Information: the negative reciprocal value of probability.
We thus learn that man is descended from a hairy quadruped, furnished with a tail and pointed ears, probably arboreal in its habits, and an inhabitant of the Old World.
For the record: Quantum mechanics does not deny the existence of objective reality. Nor does it imply that mere thoughts can change external events. Effects still require causes, so if you want to change the universe, you need to act on it.
We're going to find Marses and maybe Earths out in the solar system's attic of the Oort Cloud and the Kuiper Belt.
In spite of the opinions of certain narrow-minded people who would shut up the human race upon this globe, we shall one day travel to the Moon, the planets, and the stars with the same facility, rapidity and certainty as we now make the ocean voyage from Liverpool to New York.
