@gutenberg_org @wikipedia By postulating that chemical change was no more than the recombination of atoms - with fixed and *quantized* mass - #JohnDalton founded #QuantumTheory almost a century before #MaxPlanck quantized energy. 🤷‍♂️ #Histodons #Science #ScienceHistory

@compoundchem #JohnDalton is the true founder of #QuantumTheory because his #AtomicTheory correctly quantized MASS to explain observations in #chemistry 🧪 almost a century before #MaxPlanck quantized energy to avoid the ‘ultraviolet catastrophe’ :oh_no_bubble:.

@gutenberg_org Chemists have understood the atomic nature of physical reality since the beginning of the 19th century when #JohnDalton correctly postulated that atoms were not inert, and their mass was quantized. Btw, he is thus actually the founder of #QuantumTheory as well. 🤷‍♂️

I posted this on my now #PermanentlySuspended (by #ElmoMush ) #BirdSite account, so I guess I need to repeat it here: #Wikipedia needs to change its “History of Quantum Theory” page ⬇️, and set back the birth of #QuantumTheory to 1803, when #JohnDalton correctly hypothesized that *mass* is quantized!
