Feature for Today
Thumbnail of Ludwig Mond

On 7 Mar 1839, Ludwig Mond was born, the German-British chemist whose varied contributions to the chemical industry include perfecting a method of soda manufacture, a process for the extraction of nickel. Mond and Charles Langer coined the term “fuel cell” while attempting to generate electricity by reacting hydrogen with oxygen.

Although one of the most successful industrial chemists of his time, his name may be unfamiliar to you. To better understand the significance of his work, read more in this short Biography of Ludwig Mond.


Book of the Day
The Telephone Patent Conspiracy of 1876: The Elisha Gray-Alexander Bell Controversy and Its Many Players

On 7 Mar 1876, Alexander Graham Bell patented an “Improvement in Telegraphy” which established the principle of the telephone. He would then face a patent battle to establish priority over a competitor’s patent application filed the same day. Today's book pick is: The Telephone Patent Conspiracy of 1876: The Elisha Gray-Alexander Bell Controversy and Its Many Players, by A Edward Evenson. In addition to a dramatic account of Alexander Graham Bell’s successes, the book is a good introduction to understanding science and society at the time Thomas Alva Edison, Alexander Graham Bell and a lot of their contemporary inventors, engineers and scientists changed the world.

It is available from Amazon, typically about New from $39.95. Used from $20.85. (As of earlier time of writing - subject to change.)

Births
Thumbnail of Fritz Wolfgang London
A German-American physicist, born 7 Mar 1900, devised the first quantum mechanical treatment of the hydrogen molecule, with Walter Heitler. In a seminal paper (1927), they developed a wave equation for the hydrogen molecule with which it was possible to calculate approximate values of the molecule’s ionization potential, heat of dissociation, and other constants.
What is the name of this scientist?
Thumbnail of Stanley Lloyd Miller
Stanley Lloyd Miller, born 7 Mar 1930 is an American chemist who made a series of famous experiments beginning in 1953, to determine the possible origin of life from inorganic chemicals on the primeval, just-formed earth. He passed electrical discharges (simulating thunderstorms) through mixtures of reducing gases, such as hydrogen, ammonia, methane and water, believed to have formed the earliest atmosphere. Analysis days later showed the resulting chemicals included compounds that are the basic building blocks of proteins, together with urea, aldehydes and carboxylic acids.
What were the simple compounds thus found that can build proteins?
Deaths
Thumbnail of William Draper Harkins
William Draper Harkins (1873-1951) was an American nuclear chemist who investigated the structure of the nucleus, and first revealed the basic process of nuclear fusion, the fundamental principle of the thermonuclear bomb. In 1920, Harkins predicted the existence of a particle, in advance of its actual discovery by Chadwick's experiment.
What particle did he predict?

On 7 Mar 1799, a meeting was held at the Soho Square house of the President of the Royal Society, Joseph Banks. A list of 58 names was read of gentlemen who had agreed to contribute fifty guineas each to be a Proprietor of a new Institution for diffusing the knowledge, and facilitating the general introduction, of useful mechanical inventions and improvements; and for teaching, by courses of philosophical lectures and experiments, the application of science to the common purposes of life.
What is the name of the scientific society that was founded at his meeting?
