• The Special Theory of Relativity

  “The theory of relativity is not merely a scientific development of great importance in its own right. It is even more significant as the first stage of a radical change in our basic concepts, which began in physics, and which is spreading into other fields of science, and indeed, even into a great deal of [...]

• The Great Atlas of the Stars

  It’s a beautiful, clear night and you decide to look up, once again, at the thousands and thousands of stars you have seen all your life. Each is anonymous in the vast sweep of the heavens. It’s impossible to distinguish one bright star from another, one constellation from the next, without help. Here it is. [...]

• Natural Sinks of Co2: Palmas Del Mar, Puerto Rico, 24-27 February 1992

  Most of the attention with respect to the increase in atmospheric greenhouse gas concentrations centers around three issues: human-generated sources of carbon, mostly from burning fossil fuels; tropical deforestation, which accelerates the production of atmospheric carbon while causting havoc with biodiversity and the economic development of tropical countries; and the temperature increase that may accompany [...]

• Computational Fluid Dynamics

  This pioneering text provides an excellent introduction to CFD at the senior level in aerospace and mechanical engineering, and to some extent, chemical and civil engineering. It can also serve as a one-semester introductory course at the beginning graduate level, as a useful precursor to a more serious study of CFD in advanced books. It [...]

• Astronomical Enigmas: Life on Mars, the Star of Bethlehem, and Other Milky Way Mysteries

  Questions about the heavens are as old as civilization, perhaps as old as language itself. Is this universe infinite? What are the lights we see in the sky? In the millennia since our distant ancestors first looked up, these basic questions have been answered in countless ways, while other, more difficult questions have arisen and [...]
