If you thought that science was certain - well, that is just an error on your part.

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.
If you thought that science was certain - well, that is just an error on your part.
If any remedy is tested under controlled scientific conditions and proved to be effective, it will cease to be alternative and will simply become medicine. So-called alternative medicine either hasn't been tested or it has failed its tests.
There may be many Big Bangs that happened at various and far-flung locations, each creating its own swelling, spatial expanse, each creating a universe - our universe being the result of only one of those Big Bangs.
Down to their innate molecular core, cancer cells are hyperactive, survival-endowed, scrappy, fecund, inventive copies of ourselves.
What is especially striking and remarkable is that in fundamental physics a beautiful or elegant theory is more likely to be right than a theory that is inelegant.
History employs evolution to structure biological events in time.
