Atoms Quote by Johannes Stark
“We have learnt through experience that when an electrical ray strikes the surface of an atom, an electron, and in some circumstances a second and even a third electron, can be detached.”
About This Quote
Source Scientific Paper: On Electron Emission, 1919
When high-energy photons hit atoms, they can release one or more electrons, a process known as photoelectric effect.
In simple terms: Light can knock electrons out of atoms.

![“[Decoding the human genome sequence] is the most significant undertaking that we have mounted so far in an organized way in all of science. I believe that reading our blueprints, cataloguing our own instruction book, will be judged by history as more significant than even splitting the atom or…” quote by Francis Collins](https://sms4smile.com/quotes/img-quotes/5c6/francis-collins-5281_atoms_decoding-the-human-genome-sequence-is-th_15604.jpg)
