The idea of atomic energy is illusionary but it has taken so powerful a hold on the minds, that although I have preached against it for twenty-five years, there are still some who believe it to be realizable.

The atom can't be seen, yet its existence can be proved. And it is simple to prove that it can't ever be seen. It has to be studied by indirect evidence - and the technical difficulty has been compared to asking a man who has never seen a piano to describe a piano from the sound it would make falling downstairs in the dark.
Interpretation
The quote illustrates the challenge of understanding unseen phenomena through indirect evidence.
Carl David Anderson's quote emphasizes the complexities involved in studying subatomic particles like atoms, which, although unseen, can still be proven to exist through indirect methods. He likens this challenge to a person trying to describe a piano without ever having seen it, relying only on the sounds it produces, highlighting the limitations and difficulties inherent in scientific inquiry.
In practice
In a science lecture discussing the nature of atomic theory, this quote can illustrate the challenges of scientific evidence.
The idea of atomic energy is illusionary but it has taken so powerful a hold on the minds, that although I have preached against it for twenty-five years, there are still some who believe it to be realizable.
A problem never exists in isolation; it is surrounded by other problems in space and time. The more of the context of a problem that a scientist can comprehend, the greater are his chances of finding a truly adequate solution.
I have had my results for a long time: but I do not yet know how I am to arrive at them.
Everything was so new - the whole idea of going into space was new and daring. There were no textbooks, so we had to write them.
In our skulls, we carry around 3 pounds of slimy, wet, greyish tissue, corrugated like crumpled toilet paper. You wouldn't think, to look at the unappetizing lump, that it was some of the most powerful stuff in the known universe.
I suggest that going to Mars means permanence on the planet - a mission by which we are building up a confidence level to become a two-planet species.
