“The Bases of Modern Science” is a 1928 work by J. W. N. Sullivan that aimed to present the dominant scientific theories and discovers of his day in a non-technical way, including Newtonian Theory, Electromagnetism, Relativity, and more. John William Navin Sullivan (1886 – 1937) was a popular science writer and literary journalist. He also wrote some of the earliest non-technical accounts of Einstein’s General Theory of Relativity, and was familiar with numerous important figures in 1920s London, including Aldous Huxley, Aleister Crowley and T. S. Eliot. Other notable works by this author include: “Beethoven” (1927), “Limitations of Science” (1933), and “Contemporary Mind” (1934). Contents include: “The First Sketch”, “The Newtonian Conceptions: Space, Time, Mass”, “The Ether Theory”, “Heat and Energy”, “Electromagnetism”, “The Atom of Electricity”, “The Electric Theory of Matter”, “Relativity”, “Geometry and Physics: The Finite Universe”, “New Problems”, etc. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned introduction and biography of the author.
