‘The eightfold path: organizing the elements’ explains the history and rationale of the Periodic Table. Atomic theory was not fully accepted until Jean Perrin proved the existence of atoms in 1908. Rutherford et al went further, elucidating subatomic particles. This provided new insights into the Periodic Table, created decades earlier by Mendeleyev. Mendeleyev was not the first to attempt to group the elements. However, an improved set of atomic weights published in 1860 caused an upsurge in research. Mendeleyev's Table showed the order underlying the elements, left gaps for new elements, and questioned irreconcilable data. This data was eventually reconciled partly by Rutherford, and partly by Bohr's application of quantum theory.

Le Palais de la découverte est à un tournant de son histoire. Le Grand Palais, qui l’héberge, doit être rénové et est fermé depuis le 1er novembre 2020. La direction d’Universcience veut en profiter pour renouveler également son offre. Elle a conçu un projet, intitulé dans cet article « Palais 2024 », qui fait l’objet de nombreuses polémiques [1]. De quoi s’agit-il exactement ? Le Palais y perdra-t-il ce qui fait son ADN, ce qu’on appelle parfois « l’esprit Jean Perrin » ? Et d’ailleurs, cette vision de son fondateur, vieille de plus de 80 ans, a-t-elle encore un sens aujourd’hui ?

Chapter 3 focuses on the concept of atoms, which dates back to the ancient Greek philosopher Leucippus, who claimed that everything consisted of them. This view began to be accepted among scientists when John Dalton championed it in the 1800s, although he was wrong in his atomic structure of molecules. That was corrected not long after by Jöns Berzelius. From then on the reality of atoms, and whether those of chemistry were the same as those of physics was a matter of debate. The theory of statistical mechanics, developed in the second half of the nineteenth century, helped establish their reality for most physicists, while many chemists were won over later, in part by the periodic table developed by the Russian Dimitri Mendeleev. Nearly every scientist was finally convinced by the explanation of Brownian motion by Albert Einstein and Marian Smoluchowski, whose formulas were verified by Jean Perrin in 1909.
