Alfred J. Lotka Totally Explained

Everything about Lotka totally explained

Alfred James Lotka (March 2, 1880 - December 5, 1949) was a US mathematician, physical chemist, and statistician famous for his work in population dynamics and energetics.

Life

Born in Lemberg, Austria-Hungary (now L'viv, Ukraine), Lotka's parents were US nationals and he was educated internationally, including a degree at the University of Birmingham, England. In 1935, he married Romola Beattie. They had no children. His varied working life included:

General Chemical Company
US Patent Office
National Bureau of Standards
Editor of the Scientific American Supplement (1911-1914)
Staff member at Johns Hopkins University (1922 - 1924)
Statistician for the Metropolitan Life Insurance Company, New York (1924 until his retirement)

While at Johns Hopkins, Lotka completed his book Elements of Physical Biology (1924) in which he extended the work of Pierre François Verhulst and Vito Volterra. His name is most famously associated with the Lotka-Volterra equation of population dynamics.

Energetics of evolution

Lotka proposed the theory that the Darwinian concept of natural selection could be quantified as a physical law. The law that he proposed was that the selective principle of evolution was one which favoured the maximum useful energy flow transformation. The general systems ecologist Howard T. Odum later applied Lotka's proposal as a central guiding feature of his work in ecosystems ecology. Odum called Lotka's law the maximum power principle.

Biophysical economics

Lotka also proposed the development of a new field of economics that sought to understand the roles and influence of energy in the economy. This has become known as biophysical economics.
