Robert "The Bobby Yaga" McNees @mcnees.bsky.social · 01/07/2026Gottfried Wilhelm Leibniz was born #OTD in 1646. He was one of the great polymaths of the age, and is best known for discovering differential and integral calculus independently of Isaac Newton. 🧪 🧮 Image: Wellcome Collection 39521
Robert "The Bobby Yaga" McNees @mcnees.bsky.social · 01/07/2026Leibniz developed the calculus after Newton but published first. Newton probably developed the central ideas in the mid-1660s, and circulated unpublished papers (written as early as 1669) among colleagues. Leibniz had his main insights in the mid-1670s, and published in 1684. (2/n) 1141
