“#Science is more than a body of knowledge; it is a way of thinking. I have a foreboding of an America in my children’s or grandchildren’s time — when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues…” 1/2

Alan Turing and Christopher Strachey created a ground-breaking computer program that allowed them to express affection vicariously when so doing publicly, as gay men, was criminal.

#OTD in 1905.
Albert Einstein sends the article On the Electrodynamics of Moving Bodies, for publication in Annalen der Physik.
Reconciled Maxwell's equations for electricity and magnetism with the laws of mechanics by introducing changes to mechanics, resulting from analysis based on empirical evidence that the speed of light is independent of the motion of the observer. Discredited the concept of a "luminiferous ether".

Jean-Baptiste L. Romé de l'Isle died #OTD in 1790.
Romé de l'Isle's interest in crystals began during his captivity on the Isle of Bourbon where he had ample time to study minerals. His most comprehensive work, "Cristallographie" (1783), was published in 4 volumes. His systematic approach and detailed observations laid the foundation for modern crystallography. He is also credited with formalizing the Law of Constancy of Interfacial Angles.

Earthquake scientists are learning warning signs of the "big one." When should they tell the public?
From NBC News: "For U.S. seismologists, Japan’s 'megaquake' warning last week renewed discussion about when and how to warn people on the West Coast if they find elevated risk of a major earthquake."

"Science is nothing without generalisations... The suggestion of a new idea, or the detection of a law, supersedes much that had previously been a burden upon the memory, and by introducing order and coherence facilitates the retention of the remainder in an available form."

Canadian physicist Harriet Brooks was born #OTD in 1876.
Harriet Brooks is recognized as one of the first female nuclear physicists and a pioneer in the field of radioactivity. Under Ernest Rutherford's mentorship, Brooks conducted groundbreaking research on radioactivity. Her work on the "emanation" of radium was pivotal in identifying radon, a noble gas, as one of the decay products of radium.
American pediatrician and microbiologist Hattie Alexander died #OTD in 1968.
Alexander first became interested in influenzal meningitis. Experimenting with rabbit serums, by 1939 Alexander had developed an effective cure for influenzal meningitis. Her work with influenzal meningitis led her to study antibiotics, and she made considerable progress in understanding the genetic mutation of bacteria to develop resistance to antibiotics.

On 1 July 1913, William Henry Bragg and William Lawrence Bragg published their article 'The reflection of X-rays by crystals.'
Their work was critical in developing the field of crystallography which today underpins many technological developments in our modern society, such as drug development, nano- and biotechnology. via @NobelPrize

#OTD in 1054.
Chinese astronomers recorded the sudden appearance of a "guest star", later identified as the supernova that created the Crab Nebula (SN 1054).
Modern understanding that the Crab Nebula was created by a supernova traces back to 1921, when Carl Otto Lampland announced he had seen changes in the nebula's structure.

#OTD in 1687.
Isaac Newton publishes Philosophiæ Naturalis Principia Mathematica.
In this book Newton expounds Newton's laws of motion & his law of universal gravitation. The Principia is written in Latin and comprises three volumes, and was authorized, imprimatur, by Samuel Pepys, then-President of the Royal Society on 5 July 1686 and first published in 1687.

#OTD in 1799.
The Rosetta Stone is found in the Egyptian village of Rosetta by French Captain Pierre-François Bouchard during Napoleon's Egyptian Campaign.
It was the first Ancient Egyptian bilingual text recovered in modern times, and it aroused widespread public interest with its potential to decipher this previously untranslated hieroglyphic script.
French mathematician and academic Christian Kramp was born #OTD in 1760.
Like Bessel, Legendre and Gauss, Kramp worked on the generalized factorial function, which applies to non-integer numbers. His work on factorials is independent of that of Stirling and Vandermonde. He was the first to use the notation n! (Éléments d'arithmétique universelle, 1808). In fact, the more general concept of factorial was found around the same time by Arbogast.
Since I never did a proper #introduction here is quick one.
I mostly look for #comedy and #humor . Suggestions appreciated! @warandpeas is fabulous. I play 9 o'clock #HashtagGames at @hashtaggames.
I like reading and promoting #PinkDiscoMagazine an online, literary journal where the writers submissioms explore human sexuality.
Other things I enjoy: #zazen , #shikantaza ,#astronomy , #Linux , #archeology , and all manner of other #science and #technology posts.
Stay classy, friends.

59 years ago, the Mariner 4 probe took humanity's first close-up images of another planet.
The results shattered the myths of Mars, revealing a wispy atmosphere, -100 degree C temperatures, and a crater-pockmarked landscape.

Agnes Meyer Driscoll, known as "Miss Aggie" or "Madame X'", was born #OTD in 1889.
She was an American cryptanalyst during both World War I and World War II and was known as "the first lady of naval cryptology." Driscoll played a key role in breaking the Red Book code, a Japanese naval code, in the 1920s. She worked on machine ciphers & contributed to the development of new cryptographic techniques and devices.
#OTD in 1801.
French astronomer Jean-Louis Pons makes his first comet discovery, jointly attributed to Charles Messier. In the next 27 years he discovers another 36 comets, more than any other person in history.
He appears to have used telescopes and lenses of his own design; his "Grand Chercheur" ("Great Seeker") seems to have been an instrument with large aperture and short focal length, similar to a "comet seeker".
For anyone who needs some relaxing distraction this afternoon, here is a large bubble in a viscous fluid bumping into a smaller one, and forcing it to distort before it engulfs it (taken at the Catalyst science centre in Widnes). I played with this for AGES... so much fun!
