@mariapopova I believe you correctly surmise “how staggered (Emily Dickinson’s) pliant young mind must have been to learn that scientists had just proven the existence of atoms.”

But #physicists didn’t accept the #AtomicTheory until #AlbertEinstein demonstrated its verity through Brownian motion over a *century* after #JohnDalton proposed it.

Both ‘particle #chemistry ‘ and #QuantumChemistry predate their #physics counterparts by a century since Dalton quantized *mass*!
