"Sur la theorie du balourd du balancier" by Raymond Chaleat - Original magazine article (magazine clipping) which was removed from a 1959 Swiss magazine.

Text in the article is in French.

The opening sentences of the article read:

"Dans un article recent publie dans cette meme revue (1) M. Boolsky a donne une theorie du defaut d'equilibre du balancier. Bien que ce probleme soit definitivement resolu, tout au moins en premiere approximation, depuis un siecle par les travaux d'Edouard Phillips (2) je voudrais montrer comment le formule d'Airy permet d'obtenir une solution aussi rapide qu'elegante et rectifier certaines inexactitudes contenues dans l'article precite. F. Keelhoff avait utilise systematique, et l'on sait avec quel success (3), la formule d'Airy."

The magazine article was carefully removed from a Swiss magazine.

The article is 5 pages in length (on 3 sheets of paper).

As with most vintage magazine clippings, there is some yellowing to the paper due to age as well as light wear and small bends.

The magazine article was carefully removed directly from a Swiss magazine. It is not a copy or reproduction. The rest of the magazine is not included.
