Atoms Quote by Henry Edward Armstrong
![“[Professor Bragg asserts that] In sodium chloride there appear to be no molecules represented by NaCl. The equality in number of sodium and chlorine atoms is arrived at by a chess-board pattern of these atoms; it is a result of geometry and not of a pairing-off of the atoms.” quote by Henry Edward Armstrong](https://sms4smile.com/quotes/img-quotes/bf5/henry-edward-armstrong-46976_atoms_professor-bragg-asserts-that-in-sodium-c_999839.jpg)

About This Quote
Source Scientific Paper: Chemical Structure of Sodium Chloride, 1900s
The quote explains that NaCl crystals are arranged in a lattice, not as discrete NaCl molecules, emphasizing geometry over pairing.
In simple terms: NaCl crystals are a lattice, not molecules.

![“[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)
