    … The [British] Ministry of Defence ran a UFO desk from 1952 until 2009; it was as underfunded as its American cousins, but it collected as many sightings (12,000) and was a bit more tolerant. Many of the MoD reports were accompanied by illustrations – diagrams, photos, sketches, even paintings – that were duly filed away. When the Freedom of Information Act was passed in 2000, the UFO desk was inundated with requests. The MoD knew better than to put up a fight. They’d seen nothing definite in over fifty years, so from one point of view the files were too trivial to hide.

    David Clarke, a lecturer in journalism at Sheffield Hallam University, was made a consultant at the National Archives, where he spent ten years overseeing the UFO files’ release. There may be no extraordinary revelations in them, in the sense a UFOlogist would like, but there are fruits of a different sort. Clarke recently curated a peculiar and beautiful book called UFO Drawings from the National Archives, a showcase of the best ‘imaginative artwork’ sent to the MoD, ranging from scribbled crayon disks to diagrams in tidy pencil.

    The book takes an old question (what did these people see?), sidesteps the nutjob theories and gives us a form of social history…

    As we scan the skies, we might recall that it was on this date in 1950 that the first rocket was launched from Cape Canaveral in Florida– the “Bumper 2,” a V-2 missile base topped with a WAC Corporal rocket.

    “The dice of Zeus always fall luckily”*… 

     

    14th century medieval dice from the Netherlands

    Whether at a casino playing craps or engaging with family in a simple board game at home, rolling the dice introduces a bit of chance or “luck” into every game. We expect dice to be fair, where every number has equal probability of being rolled.

    But a new study shows this was not always the case. In Roman times, many dice were visibly lopsided, unlike today’s perfect cubes. And in early medieval times, dice were often “unbalanced” in the arrangement of numbers, where 1 appears opposite 2, 3 opposite 4, and 5 opposite 6. It did not matter what the objects were made of (metal, clay, bone, antler and ivory), or whether they were precisely symmetrical or consistent in size or shape, because, like the weather, rolls were predetermined by gods or other supernatural elements.

    All that began to change around 1450, when dice makers and players seemingly figured out that form affected function, explained Jelmer Eerkens, University of California, Davis, professor of anthropology and the lead author of a recent study on dice.

    “A new worldview was emerging — the Renaissance. People like Galileo and Blaise Pascal were developing ideas about chance and probability, and we know from written records in some cases they were actually consulting with gamblers,” he said. “We think users of dice also adopted new ideas about fairness, and chance or probability in games”…

    From fate to fairness: how dice changed over 2,000 years to be more fair: “It’s not how you play the game, but how the dice were made.”

    As we consider the odds, we might send frontier-challenging birthday greetings to a man who tempted chance– Charles Elwood “Chuck” Yeager; he was born on this date in 1923.  A flying ace, test pilot, and ultimately U.S. Air Force General, Yeager became the first human to officially break the sound barrier when, in 1947, he flew the experimental Bell X-1 at Mach 1 at an altitude of 45,000 ft. 

    Perhaps as famously, Yeager was a mentor and role model for the first class of NASA astronauts, as memorialized in Tom Wolfe’s The Right Stuff, and Philip Kaufman’s film adaptation.  On finishing high school at the beginning of World War II, Yeager had enlisted in the Air Force as a private; he served a mechanic before being accepted into the enlisted flight program, from which he graduated as a “Flight Officer” (equivalent to a Chief Warrant Officer).  His extraordinary skill as a pilot fueled his continued rise through the ranks.  But NASA’s requirement that all astronauts have college degrees disqualified Yeager from membership in the space program.  So though he was by most accounts far the most qualified potential astronaut, he became instead their head teacher, the first commandant of the USAF Aerospace Research Pilot School, which produced astronauts for NASA and the USAF.

    “You can’t trust water: Even a straight stick turns crooked in it”*… 

     

    New Yorkers like to say their tap water is the best in the world. Surely, then, it’s worth a $1.99-a-month subscription to drink it when you’re away from your sink—right?

    That is the concept behind Reefill, a startup that aims to bring the subscription model to the simple, free act of filling up a water bottle at a café. The company wants to build 200 smartphone-activated water fountains inside Manhattan businesses, less to make money off the Nalgene crowd than to hit Dasani, Aquafina, and the wasteful consumption habits of bottled water–guzzling Gothamites…

    Just as one field of startups is dedicated to doing what Mom won’t do for you anymore, another is reviving the infrastructure of the 19th century. Uber eventually found its way to the bus; Reefill, to the public drinking fountain…

    As we pine for the days of bigger visions, we might recall that it was on this date in 1961 that President John F. Kennedy gave the historic speech before a joint session of Congress that set the United States on a course to the moon.

    In his speech, Kennedy called for an ambitious space exploration program that included not just missions to put astronauts on the moon, but also a Rover nuclear rocket, weather satellites, and other space projects.

    As we sample the cheese, we might send high-flying birthday greetings to Octave Chanute; he was born on this date in 1832.  A civil engineer who was a pioneer in wood preservation, primarily as applied in the railroad industry, he is better remembered for his application of these techniques first to box kites, then to the struts in the wings of gliders.  Through thousands of letters, he drew geographically-isolated aviation pioneers– including Orville and Wilbur Wright– into an informal international community: he organized sessions of aeronautical papers for the professional engineering societies that he led; attracted fresh talent and new ideas into the field through his lectures; and produced important publications.  At his death he was hailed as the father of aviation and the heavier-than-air flying machine.

    If any intelligent life in our galaxy intercepts the Voyager spacecraft, if they evolved the sense of vision, and if they can decode the instructions provided, these 116 images are all they will know about our species and our planet, which by then could be long gone…

    When Voyager 1 and Voyager 2 launched into space in 1977, their mission was to explore the outer solar system, and over the following decade, they did so admirably.

    With an 8-track tape memory system and onboard computers that are thousands of times weaker than the phone in your pocket, the two spacecraft sent back an immense amount of imagery and information about the four gas giants, Jupiter, Saturn, Uranus, and Neptune.

    But NASA knew that after the planetary tour was complete, the Voyagers would remain on a trajectory toward interstellar space, having gained enough velocity from Jupiter’s gravity to eventually escape the grasp of the sun. Since they will orbit the Milky Way for the foreseeable future, the Voyagers should carry a message from their maker, NASA scientists decided.

    The Voyager team tapped famous astronomer and science popularizer Carl Sagan to compose that message. Sagan’s committee chose a copper phonograph LP as their medium, and over the course of six weeks they produced the “Golden Record”: a collection of sounds and images that will probably outlast all human artifacts on Earth…

    As we contemplate co-habitation of the universe, we might send out-of-this-world birthday greetings to Alan B. Shepard; he was born on this date in 1923.  A naval aviator and test pilot, he was selected in the first class of American astronauts, the “Mercury Seven”; in 1961, he piloted the first American manned mission, “Freedom 7,” becoming the first American (and second man, after Yuri Gagarin) into space.  Ten years later, he was part of the Apollo 14 crew, piloting the lunar module for Nasa’s third successful moon landing.

    This map, published by South Dakotan Orlando Ferguson in 1893, offers a unique vision of the Earth as a concave field, with a round convex area in the middle. Surrounded by Bible passages arguing against the idea of a spherical Earth and embellished with a small illustration of men grasping desperately onto a spinning globe, the map begs its viewers to order Ferguson’s book on “this Square and Stationary Earth,” which “knocks the globe theory clean out.”

    Historian Christine Garwood writes that the idea that people in the medieval period believed in a flat Earth before Columbus roundly disabused the world of that notion is reductive. Some medieval thinkers realized the truth, and people have persisted in believing in a flat Earth far past the time of Columbus. “Flat-earth belief has a chronology far stranger than all the inventions,” she writes. The idea’s resurgence in the 19th century is part of that strangeness.

    In the 19th-century United States, pamphleteers and authors of varying levels of credibility debated the flat-Earth theory vigorously. In an issue of the journal Miscellaneous Notes and Queries, published in 1896, the editors included Ferguson’s book in a list of other recent titles questioning the dominant scientific perspective on the nature of the globe. Some of these: Eclectic or Cosmo-Enspheric Astronomy: The firmament a hollow sphere, and we live inside of it (Ulysses G. Morrow, 1894); One Hundred Proofs that the Earth is Not a Globe (William Carpenter, 1885); and Terra Firma. The Earth Does Not Move. Is not a Globe (W.M. Herd, 1890)…

    As we reach for the stars, we might recall that it was on this date in 1988 that NASA launched the space shuttle Discovery, marking America’s resumption of manned space flight following the 1986 Challenger disaster.  It was the first of Discovery‘s two “Return To Flight” assignments; it flew the “twin” missions in 2005 and 2006 that followed the Columbia disaster in 2003.

    “If we all worked on the assumption that what is accepted as true really is true, then there would be little hope for advance”*… 

     

    Some guys spend their spare time restoring automobiles, devoting garage space to chocked-up Corvettes and Camaros.  Dave Pares, an adjunct professor at the University of Nebraska- Omaha,  is making his own warp drive.

    In theory, a warp drive contracts space in front of a space vessel and expands it at the back. The ship itself speeds along inside what is called a “warp bubble.”  As theoretical physicist Miguel Alcubierre explained in 1994, if such an artificial warping of space — essentially picking up a piece of fabric of space=time at two points and bringing them together — could be accomplished, it would allow a space ship to travel incredible distances incredibly quickly, while avoiding the speed-of-light problem.

    NASA has explored the prospect, but been put off by the technical and financial challenges of developing the power source that it believes would be necessary.  But Pares believes he can accomplish warping with low power– indeed, with the voltage available in his garage.

    So far, Pares seems primarily to have attracted the attention of UFO enthusiasts; NASA and academic journals have (more and less politely) turned him away.  But retired UN-O physics professor Jack Kasher is cautiously optimistic:

    It is so far out there, he’s not going to get funding to do it. If it’s going to be done, it’s going to be done in his garage…  A lot of people are going to flat-out dismiss it off the top, but I think he’s crossed some kind of bridge here, just showing this is possible with reasonable energy.  It wouldn’t surprise me if NASA latches on to this.

    In any case, as Kasher notes, at a time when the scientific and technical mainstream had written off manned flight, the Wright Brothers took their first critical steps in their Ohio bike shop.

    As we put on our helmets, we might recall that it was on this date in 1949 that Britain’s first “launderette”– self-service, coin-operated laundry– opened on Queensway in London.  The very first coin-op laundry had opened in 1936 in Ft. Worth, Texas (where it was known for a time as a “washateria”).

    While these self-service laundries are still known as launderettes in the U.K., they are now widely called “laundromats” in the U.S., Canada, Australia and New Zealand (a genericization of the trademark of the coin-op washers and dryers developed and sold by Westinghouse).

    “Outer space is so empty”*… 

     

    At the furthest-most reaches of the observable universe lies one of the most enigmatic mysteries of modern cosmology: the cosmic microwave background (CMB) Cold Spot.

    Discovered in 2004, this strange feature etched into the primordial echo of the Big Bang has been the focus of many hypotheses — could it be the presence of another universe? Or is it just instrumental error? Now, astronomers may have acquired strong evidence as to the Cold Spot’s origin and, perhaps unsurprisingly, no multiverse hypothesis is required. But it’s not instrumental error either…

    The Cold Spot area resides in the constellation Eridanus in the southern galactic hemisphere. The insets show the environment of this anomalous patch of the sky as mapped using PS1 and WISE data and as observed in the cosmic microwave background temperature data taken by the Planck satellite. The angular diameter of the vast supervoid aligned with the Cold Spot, which exceeds 30 degrees, is marked by the white circles.

    As we boldly go, we might recall that it was on this date in 1962 that NASA launched the Ranger 4, the first U.S. spacecraft to reach another celestial body.  Ranger 4 was designed to transmit pictures to Earth and to test the radar-reflectivity of the lunar surface during a period of 10 minutes of flight prior to crashing upon the Moon, “rough-landing” a seismometer capsule as it did.  In the event, an onboard computer glitch caused failure of the solar panels and navigation systems; as a result the spacecraft crashed on the far side of the Moon three days after it’s launch without returning any scientific data.  Still, the “landing” was a first.

    If the range of habitable radii is sufficiently broad, most inhabited planets are likely to be closer in size to Mars than the Earth. Furthermore, since population density is widely observed to decline with increasing body mass, we conclude that most intelligent species are expected to exceed 300kg…

    As we phone home, we might recall that it was on this date in 1960 that the first weather satellite, TIROS I, was launched from Cape Kennedy (or Canaveral, as then it was) and sent back the first television pictures from space. The first in a long series of launches in the TIROS program (Television Infrared Observation Satellite), it was NASA’s initial step, at a time when the effectiveness of satellite observations was still unproven, in determining if satellites could be useful in the study of the Earth.  In the event, TIROS I and it successors proved extremely useful in weather forecasting.
