The first volume, 16 pages long, had 10 short articles on topics such as the making of optical glass, whale watching in the Bermudas, and the performance of a pendulum watch at sea. By all accounts this first scientific journal was a success, and the Philosophical Transactions of the Royal Society is still being published today. The first decades of its publication saw many memorable papers, including Isaac Newton’s first publication, on his prism experiments of 1666.3 Newton’s experience, however, highlights the tentativeness of this new medium for scientific publication in the 17th century. After numerous scientists published letters challenging Newton’s new optical theory, Newton grudgingly responded but never again published a new scientific result in a journal. Instead, he fell back on the book as the preferred medium for expressing his ideas, publishing his masterworks the Principia in 1687 and Opticks in 1704.
