On 10 Apr 1863, Paul-Louis-Toussaint Héroult was born, the French chemist who invented the electric-arc furnace.

In this early Scientific American article from 1891, you can read of the status at that time of a familiar element, for which Héroult devised a non-smelting process to separate it from its ore.


Book of the Day
Banana: The Fate of the Fruit That Changed the World

In 1633, an unripe bunch of bananas was given to apothcary Thomas Johnson by John Argent, President of the College of Physicians (who received it from a merchant just returned with it from the Bahamas). Johnson hung it at his shop in Snow Hill, London, where it ripened about the beginning of May, and lasted until June. Being the first bananas seen in Britian, the display caused a sensation.

Beginning in the nineteenth century, the banana was cultivated in plantations, created by a ruthless and increasingly powerful company. The history of the big business of banana production and distribution includes controversy, deceit, violence, exploitation, and involvement in a bloody coup.

Today's book pick is: Banana: The Fate of the Fruit That Changed the World, by Dan Koeppel, who also describes what is known of the beginnings of the banana itself, and its place in modern agriculture and world markets. It is a seedless fruit with a unique reproductive system, by which every banana is a genetic duplicate of the next, and therefore susceptible to the same blights. Today’s yellow banana, the Cavendish, is increasingly threatened by such a blight—and there’s no cure in sight.

It is available from Amazon, typically about New from $16.80. Used from $1.93. (As of earlier time of writing - subject to change.)


Quotations for Today
Thumbnail of Jean-Baptiste-André Dumas
In chemistry, our theories are crutches; to show that they are valid, they must be used to walk... A theory established with the help of twenty facts must explain thirty, and lead to the discovery of ten more.
— Jean-Baptiste-André Dumas, French chemist (died 10 Apr 1884). quote icon
Thumbnail of Samuel Hahnemann
I do not know if I am mistaken, but it seems that one can obtain more truths, important to Humanity, from Chemistry than from any other Science.
— Samuel Hahnemann, German chemist and physician (born 10 Apr 1755). quote icon
Thumbnail of Robert Burns Woodward
The structure known, but not yet accessible by synthesis, is to the chemist what the unclimbed mountain, the uncharted sea, the untilled field, the unreached planet, are to other men … The unique challenge which chemical synthesis provides for the creative imagination and the skilled hand ensures that it will endure as long as men write books, paint pictures, and fashion things which are beautiful, or practical, or both.
— Robert Burns Woodward, American chemist (born 10 Apr 1917). quote icon

Sam Loyd (1841-1911) was an American puzzle-maker who studied engineering and intended to become a steam and mechanical engineer but he soon made his living from his puzzles, chess problems and mathematically based games. His most famous puzzle was the 15 Puzzle which he produced in 1878. The craze swept America where employers put up notices prohibiting playing the puzzle during office hours.

In 1815, the massive eruption of Mount Tambora was its most powerful in 1,600 years. It formed a crater 5-miles across its island, lowered the island by 4,000 feet, and killed 10,000 people. The series of eruptions between 5 Apr and 15 Apr had worldwide effects more far-reaching than the famous 1883 eruption of Krakatoa. The record amounts of ash Tambora spewed into the atmosphere encircled the globe, screened the sun’s light and caused a global drop in temperature.
In which country is Mount Tambora?
