Theosophy (Wikipedia) Theosophy is a religion established in the United States during the late 19th century. It was founded primarily by Helena Blavatsky and draws its teachings predominantly from Blavatsky’s writings. Categorized by scholars of religion as both a new religious movement and as part of the occultist stream of Western esotericism, it draws upon both older European philosophies such as Neoplatonism and Indian originated religions such as Hinduism and Buddhism.

John von Neumann (Wikipedia) John “Johnny” von Neumann (/vɒn ˈnɔɪmən/; Hungarian: Neumann János Lajos, pronounced [ˈnɒjmɒn ˈjaːnoʃ ˈlɒjoʃ]; December 28, 1903 – February 8, 1957) was a Hungarian-American mathematician, physicist, computer scientist, engineer and polymath. He was regarded as having perhaps the widest coverage of any mathematician of his time and was said to be “the last representative of the great mathematicians who were equally at home in both pure and applied mathematics”. He integrated pure and applied sciences.
Calculus (Wikipedia) Calculus is the mathematical study of continuous change, in the same way that geometry is the study of shape, and algebra is the study of generalizations of arithmetic operations.
