On 6 Aug 1753, Professor Georg Richmann of St. Petersburg, Moscow, was in his house, preparing an experiment with lightning. One year after Benjamin Franklin's kite experiment, Richmann ran a wire from the top of his house down into a room and attached it to an iron bar suspended above “the electric needle” and a bowl of water partly filled with iron filings.

Franklin learned of the outcome of the experiment by letter, and published it in the Pennsylvania Gazette, and thus it entered history. If you don't know the notable outcome, you can read a summary of the observed results in The Lightning Experiment of Georg Richmann.


Book of the Day
The story of Jodrell Bank

On 6 Aug 2012, Sir Bernard Lovell died, leaving a legacy of an important radio telescope observatory known as Jodrell Bank. He needed persistence for raising the funds necessary, but by 1957, it was one of the few stations able to track the first artificial satellite, Sputnik I. Today's book pick is: The story of Jodrell Bank, by Bernard Lovell. It is always a pleasure to read in his own words the accomplishments of a man that through thick and thin produced a body of work, and a legacy, for which he worked so hard.

It is available from Amazon, typically about New from $84.84. Used from $3.73. (As of earlier time of writing - subject to change.)


Quotations for Today

Sir Alexander Fleming, born 6 Aug 1881, was a Scottish bacteriologist. In 1928, while working on influenza virus, he observed that mould had developed accidently on a staphylococcus culture plate and that the mould had created a bacteria-free circle around itself. He experimented further and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times. The active substance initiated the highly effective practice of antibiotic therapy for infectious diseases.
What name did he give the active substance?
