|John Dalton physics
invisible & irreducible atoms remained controversial since Democritus in the fifth century until John Dalton seeing that common chemical processes produced elements in fixed proportions— so much hydrogen per oxygen in water so much oxygen per carbon in carbon dioxide claimed that chemical elements are made of atoms atoms of the same element have the same weight atoms of different elements have different weights atoms combine in only small whole-number ratios to form molecules (which he called “compound atoms”) and atoms cannot be created or destroyed (by chemical processes).
Describing atoms as spherical bodies, Dalton proposed a uniform notation for atoms and molecules —each a circle containing a letter or decoration. These circles formed an alphabet which chemists could use to spell more complex compounds. His circle for hydrogen contained a dot— same as the Egyptian hieroglyph for the sun, ‘ra,’ which had not yet been decyphered.
If an atom cannot be destroyed, then these are not atoms— lives, families, languages, tribes, happiness, peace of mind, faith, belief, hope. If I were to symbolize my love with a plus-sign and put that sign in a circle, then I would be trying to say my love cannot be destroyed.
