TODAY IN SCIENCE HISTORY
NEWSLETTER - 22 SEPTEMBER

Feature for Today
On 22 Sep 1791, the prolific researcher, Michael Faraday was born, whose name will be very familiar to any student of physics.

He was also very popular lecturer, who started a series of Christmas Lectures for a juvenile audience, complete with interesting demonstrations. These lectures continue under his name to this day, from the same lecture theatre, and broadcast to an even wider television audience.

His theme for the 1860 Christmas Lectures was A Course of Six Lectures on the Various Forces of Matter, and Their Relation to Each Other. Decades before Edison claimed fame for his invention of a practical light bulb, electric lighting existed in the form of arc lamps. In sixth of these lectures, Light-House Illumination—The Electric Light, Faraday explains the optics of lighthouses, and the early efforts to replace oil burners with electric lighting. Which of course, necessitated the generation of electricity. And who better to explain that than Faraday, the renowned investigator of electromagnetism.

Book of the Day
The Electric Life Of Michael FaradayOn 22 Sep 1791, Michael Faraday was born, who discovered electromagnetic induction. His lectures engaged the public. Faraday is one of the most significant figures in experimental physical science, so today's Science Store pick is The Electric Life Of Michael Faraday, by Alan W. Hirshfeld. You may find this biography so compelling and inspiring that you may find tears in your eyes as you read in the last pages of his funeral, at the end of such a productive life. This is a scientist everyone should know as a person. New $24.00, Price $16.32.
Yesterday's pick: The Toy Story: The Life and Times of Frank Hornby.

Quotations for Today

"I am busy just now on electro-magnetism, and think I have got hold of a good thing, but can't say. It may be a weed instead of a fish that, after all my labour, I may at last pull up."
- Michael Faraday, English physicist and chemist (born 22 Sep 1791) Quotes Icon
"(The human control of atomic energy could) virtually provide anyone who wanted it with a private sun of his own."
Frederick Soddy, English Nobel prize-winning chemist who investigated radioactive transformations (died 22 Sep 1956) Quotes Icon

"Scientists have one thing in common with children: curiosity. To be a good scientist, you must have kept this trait of childhood, and perhaps it is not easy to retain just one trait. A scientist has to be curious like a child; perhaps one can understand that there are other childish features he hasn't grown out of."
- Robert Frisch, Austrian-British nuclear physicist (died 22 Sep 1979) Quotes Icon

QUIZ
Before you look at today's web page, see if you can answer some of these questions about the events that happened on this day. Some of the names are very familiar. Others will likely stump you. Tickle your curiosity with these questions, then check your answers on today's web page.
Births
Michael Faraday, born on 22 Sep 1791, made many experiments that contributed greatly to the understanding of electromagnetism. Although one of the greatest experimentalists, he was largely self-educated. He began with an appointment to be assistant to Sir Humphry Davy. Faraday initially concentrated on analytical chemistry, and discovered benzene in 1825. By far, however, his most important work was in electromagnetism, in which field he discovered electromagnetic induction.
At which laboratory did he and Davy work?
Deaths
Frederick Soddy (1877-1956) was an English chemist and physicist who received the Nobel Prize for Chemistry in 1921 for investigating radioactive substances. He studied, and coined the name of "isotopes."
Formed from two Greek words, what is the meaning of the word "isotope"?
Events
On 22 Sep of a certain year, the first time train dispatching by telegraph in the U.S. took place when superintendent Charles Minot, of the Erie Railroad telegraphed 14 miles to Goshen, N.Y., to delay a train so that his train would not have to wait. Within weeks, all Erie trains were controlled by the telegraphed orders of a train dispatcher. Until that time the timetable was the sole authority for moving trains on the line.
In what decade did this occur?
On 22 Sep 1955, commercial television broadcasting began in Britain by ITV, starting with a station serving the London area. The first advertisement was shown at 9:12 pm showing Gibbs SR toothpaste in a block of "'ice."
What was the name of this first English commercial TV station?
