On behalf of the Project Vox team at Duke, we’re delighted to announce the publication of Émilie Du Châtelet’s Essai sur l’optique on our website. This is the first time that the text has been published in any language. The text was found by our colleague Dr. Fritz Nagel, of the Bernoulli-Euler-Zentrum in Basel, and the transcription of the work was led by Duke PhD student Bryce Gessell. An English translation of the Essai will also be available on our site in the coming months.
