In 1872 Charles Darwin completed what may be the first example of a prospective "single-blind" study of human perception of emotional expression.
Through scrutiny of Darwin's previously unpublished handwritten notes on his experiments, neuroscientists have demonstrated how this early experiment has direct implications to current work today in the areas of schizophrenia, autism spectrum disorders and other neuropsychiatric conditions.

Science, outside some in the climate community (*), is anti-authoritarian. There is no voting to create a consensus in science, no appeals to authority - science is vulnerable every single day of the year, to experiments, to revisions and to complete debunking by new generations of scientists who, like gun-slingers in the Old West, want to make their name taking down the big guys.
Great thinkers like Einstein and Aristotle have been slain by the scientific method so it can happen to anyone - and that power is what made freedom possible, according to Timothy Ferris, emeritus professor at the University of California, Berkeley, former editor of Rolling Stone magazine, and book author.
This must rank up there as the most bizarre holiday destination in the world.
Trinity is the location of the first nuclear test by the Manhattan Project. The world's first plutonium bomb was detonated there on 16 July 1945 - similar to the one dropped on Nagasaki. The site is now part of the White Sands Missile Range, and unbelievably is open to the public.
Well, almost open to the public! The nuclear tourist can visit Trinity on two days of the year; on the first Saturday in April and October. The next visitor day is thus on the 3rd April 2010 which falls on the Easter weekend. Note also that these days coincide with guided tours at the Very Large Array nearby.
Easter is the most important festival in the Christian calendar as it defines a number of theological doctrines. However, Easter has always been a movable feast which can take place on any date between 22 March and 25 April inclusive. The actual methods for calculating Easter have changed down the centuries and, whereas the Gregorian calendar is probably the simplest solar calendar we will ever have, the ecclesiastical calendar on which Easter is based seems to have got ever more obscure and intricate.
Baird : The Wonder Of Television
The following article was scanned by me from
"The Wonder Encyclopedia For Children"
Apart from minor adjustments to layout and removal of page references it is verbatim.
I present it here as a view from the past, when television was a brand new scientific achievement being presented as a new wonder to children and using the latest photographic illustration techniques.
John Logie Baird describes broadcast television in his own words.

Electric Eyes that Scan the World

Now here’s an interesting chap.
The Göttingen Academy of Sciences  was founded in 1751 with Albrecht von Haller (1708 – 1777)  as the main driving force in the setting it up. He had very definite views on what an academy should be. The historian Morris Kline writes:–
The Royal Mail has launched a Special issue commemorating the 350th Anniversary of The Royal Society. Ten specially-commissioned stamps have been issued showing some of the most famous scientist in the Royal Society's long history.
The question is... who are they? (and no peeking
at the Royal Mail website!)
An Argument For Cross-Disciplinary Studies
Lack of experience diminishes our power of taking a comprehensive view of the admitted facts. Hence those who dwell in intimate association with nature and its phenomena grow more and more able to formulate, as the foundations of their theories, principles such as to admit of a wide and coherent development: while those rendered unobservant of the facts by their devotion to abstract discussions are too ready to dogmatize on the basis of a few observations.'On Generation and Corruption'Aristotle
(384 BC – 322 BC)
Why did the Babylonians and the Greeks approach astronomy so differently? In my last post
I quoted Toulmin and Goodfield from their history of dynamics and astronomy, The Fabric of the Heavens
, where they argue that the Babylonians, because of their careful record keeping and math skills, could make excellent astronomical predictions, but they couldn't explain why those predictions worked. The Greeks on the other had were obsessed with explanation and theory, and were for a long time relatively bad at astronomical prediction.
There is a plaque on the south side of Trafalgar Square, just behind the statue of Charles I, that is the reference point from which all distances from London are measured. However, there is a far more intriguing plaque of scientific interest that is also associated with a tale of official incompetence and disaster.
