A biographical account of the life and scientific contributions of Charles Wheatstone is presented. Besides his invention of the "wheatstone bridge", Wheatstone suggested the use of rotating mirrors for measuring small time intervals and spectroscopic analysis of metals. He also invented numerous devices in electric telegraph systems and…

The development of the science of genetics through the confluence of separate theories is surveyed in this essay. An outline of classical genetics is emphasized. Interruptions in the continuity of development and the influence of genetics on the biological sciences and man as a social animal are discussed. (VW)

This history for molecular genetics and its explanation of DNA begins with an analysis of the Golden Jubilee essay papers, 1955. The paper ends stating that the higher nervous system is the one major frontier of biological inquiry which still offers some romance of research. (Author/VW)

Suggests that the physical meaning of work is closer to the colloquial meaning than any other terms in mechanics. Reviews history to show that force times distance was used to refer to the output of engines since the early 18th century, but none became widespread and 'work' quickly became the preferred term after G. Goriolis suggested it in 1829.…
