Physics in 16th, 17th and 18th century

16th century

In the 16th century Nicholas Copernicus revived the heliocentric model of the solar system devised by Aristarchus (which survives primarily in a passing mention in the Sand Reckoner of Archimedes). When this model was published at the end of his life, it was with a preface by Osiander that piously represented it as only a mathematical convenience for calculating the positions of planets, and not an account of the true nature of the planetary orbits.

In England William Gilbert (1544-1603) studied magnetism and published a seminal work, De Magnete (1600), in which he thoroughly presented his numerous experimental results.

PayPal history

Beginnings

PayPal was founded in December 1998 by Peter Thiel and Max Levchin. One of its first premises was the 165 University Avenue office in Palo Alto, California, home of a number of other noted Silicon Valley startups. On the business side, many of its initial recruits were alumni of The Stanford Review, which was also founded by Peter Thiel. Most of the early engineers hailed from the University of Illinois at Urbana-Champaign, recruited by Max Levchin. In its initial incarnation, PayPal was a service for users to send money via PDAs, with actor James Doohan, Star Trek's "Scotty," as its spokesman. The PDA software was later discarded in favor of a web-based system that became popular with eBay's millions of buyers and sellers. Coupled with aggressive marketing campaigns offering $10 (and later $5) for new users to sign up, the firm grew at a meteoric rate of 7–10 percent per day between January and March 2000.

The legend of the vampire was and still is deeply rooted in Romania. There have always been vampire-like creatures in the mythologies of many cultures. However, the vampire, as he became known in Europe and hence America, largely originated in the lands of eastern Europe.
