Antoine Lavoisier, Joseph Louis Proust, and John Dalton first discovered the laws of conservation of mass, simple proportions, and multiple proportions, respectively, which led to the hypothesis that matter was made of atoms. Dalton first made this conjecture, Amedeo Avogadro corrected it, Ludwig Boltzman noticed that many laws such as the ideal gas law and the second law of thermodynamics were all emergent properties of atoms colliding and statistically obeying Newton’s laws, and Einstein could count the number of atoms in a gram of hydrogen by observing its Brownian motion. It was the founders of quantum mechanics, Bohr, Rutherford, etc. that gave us conclusive evidence and the structure of an atom.

However, atomism goes back to the greek philosophers Leucippus and Democratus (the first materialists), who used atomism to reconcile the Eleatic and Heraclitean schools of philosophy. Epicurus furthered the idea by saying the atoms were indeterministic (similar to quantum mechanics) and Plato claimed that the atoms were not fundamental (subatomic particles?). However, Aristotle’s idea that matter was continuous prevailed, and became the Christian Church’s doctrine for thousands of years, and any atomistic or materialistic voices were suppressed.

i was hoping to know which scientist did express this idea that “All matter is made of atoms”.

I hope you plan to have a posting with links to all of these when you’re through.

Oh! And thanks for adding the search feature. Mucho apreciado!
