Taking a cue from the film Close Encounters of the Third Kind, a major internet retailer, we learn via Marginal Revolution, has developed a sort of tonal pass-key that admits or restricts users from collaborative projects on the basis of being in tune, with those discordant or cacophonous ones being identified as inauthentic members.
Although I like to keep my computing time quiet and on mute, I think I might prefer this sort of harmonious CAPTCHA (which is an acronym for Completely Automated Public Turing test to tell Computers and Humans Apart, which I think the machines have out smarted long ago) to the usual tests of humanity. Many of the firm’s ideas reportedly have not progressed beyond the sandbox of claims jumping but it’s nonetheless intriguing that being able to sculpt mashed potatoes into Devil’s Tower or that subterranean subterfuge might be indicative of alien visitations is certainly worthy of examination.

Engrossingly, Mental Floss tells the story of the criminally insane former American civil war medical officer and surgeon who was one of the founding (and among the most prodigious) contributors to the Oxford English Dictionary, Doctor William Chester Minor.
The crowd-sourced, definitive reference book differs from other dictionaries insofar as it is a descriptive account of the language that traces the development of words (from the nonce, to slang and to jargon) and changes in meaning and nuance—rather than a prescriptive effort that informs speakers of the correct way to speak, and in order to capture a comprehensive picture of the spoken and written word, the editors enlisted thousands of volunteers to tease out shades of meaning, and confined to Broadmoor asylum, surrounded by stacks of books from all eras, Minor found new meaning for his existence and working on the project alleviated his mental condition during daylight hours—at least. A combination of a severe persecution-complex and undiagnosed nymphomania (sexually frustrated due to his upbringing by strictly religious, missionary parents) eventually led to his honourable discharge from the army, and wracked by a recurring nightmare that quickly became a consuming reality—probably also exacerbated by the horrors of the battlefield and being made to brand a defector with a “D” on his cheek with a cattle iron.
Hoping to escape his nocturnal visitations, Minor used his retirement windfall to relocate to England but to his horror, the mysterious intruder had followed him and menaced him still.  Minor acquired a pistol so as to defend himself and when the intruder presented himself next, Minor brandished the weapon and the intruder fled.  Minor pursued him outside and shot the first bystander he encountered and was thereafter institutionalised for the rest of his life.  Not to make light of mental illness and certainly working on compiling a dictionary that is a reflection of English as she is spoke throughout the ages brought the inmate moments of great lucidity as he helped give to the world a great academic resource, but I do have to wonder what it means that our etymology and shades of meaning is influenced by one so haunted by incubi or succubi.   Minor stopped contributing to the project after being one day possessed of bereaving himself of his member but even that did not cure him of his psycho-sexual burdens, but not before the publisher behind this enterprise got to meet with his chief benefactor and quickly forgot that the encounter was taking place in an insane asylum.

We had not realised that the upper Rhein valley acquired its present appearance not by Nature but rather through extensive engineering until reading this profile on Johann Gottfried Tulla.
Of course many of the ancient palaces and fortifications that lend the river its romantic airs existed prior to Tulla’s excavation and construction that worked to straighten meandering sections, deepen the bed to improve navigation and remove numerous islets that began in the first decade of the nineteenth century, but the character of place was really transformed by the efforts to tame the marshlands and regulate flooding. Transportation infrastructure was the primary motivation and not tourism, but the manicured embankments did make for a good monumental showcase. Virtually unrecognisable from an ecological standpoint, Tulla’s landscaping and construction would be considered criminal today and an assault on the environment, it’s hard to imagine villages developing in swampier climes and malaria (which Tulla himself ultimately succumbed to) was rampant in the area. The efforts to mitigate flooding in the industrially-important cities of Koblenz, Bonn and Köln produced flooding further downstream, and presently work is being undertaken to re-naturalise and de-constrain the river as much as possible and allow it to choose its own course.

The detection of gravitational waves from the impact of the collision of two neutron stars (the event is named a kilonova)—thanks to the addition of a third facility near Pisa—allowed astronomers to triangulate the source of the bloop and trace it back to its origins in the sky and pair the visual the remnants (the previous soundings involving black holes) of the explosion with its sound-profile.
Equipped with this extra dimension of data, scientists were able to study the coronal spectra to confirm the conjecture that such violent events seed the Cosmos with gold and other heavy elements and are the source of gamma ray bursts. Moreover, measurements once refined may show the lag time between the propagation of waves of light versus waves of gravity and if seen to be reliable in their spread, could be a second cosmic distance ladder to compliment the Doppler shift of distant objects moving away or moving towards us.
