1803 marks the birth of #QuantumTheory.#JohnDalton quantized mass when he postulated his essentially correct #AtomicTheory. ✅
-
@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:.

@nitpicking @compoundchem 6:02 am is the time that Masters of the Atomic Domain ‘raise a glass’ (of orange juice?) to #chemistry on #MoleDay (10/23) in the #UnitedStates.

@sellathechemist @compoundchem phallotoxins like phalloidin, also fascinating. Used extensively in #CellBiology research to label #Actin #Cytoskeleton, but i don't really know the route of toxicity in animals.

The first three were taken with my macro. #PanamanianGoldenFrog

We have poison dart frogs (and Panamanian Golden Frogs) at #SenecaParkZoo, but I never knew that was how they produced their neurotoxins. I'll have to grab some pics with my fancy new macro lens.

@karlauerbach @compoundchem Public health and solid waste people use the word “putresible” in regulatory language. Food, dead animals, and other waste that are capable of putrefaction (putrescible) must be disposed of weekly or twice-weekly with whatever else is defined as “garbage” locally to avoid odor and fly breeding. I didn’t know that there was any specific smelly chemical associated with the term. Non-putrescible solid wastes may be disposed of less frequently and are covered by many terms that may differ by locale—the #USPHS used to use “garbage” for any mixture of waste that included putrescibles, “rubbish” for non-putrescible waste, “municipal solid waste” for either from residential & commercial sources, “debris” for various kinds of inert wastes, and “refuse” or solid wastes for all of it. Flood wastes are a special case, since no matter what it started out as, it’s been contaminated by a mix of putrescible and toxic wastes of largely unknown types and concentration. #Helene #Cleanup
