Santa’s Lap: Unusual Maps Of London Every day until Christmas we will be pointing you in the direction of a London-inspired Christmas gift that (with a bit of luck) you won’t already have on your list. Climb up onto our collective lap and we’ll see what we can move from our sack to your stockings… Everybody loves an old map. We know this from our page-views. Whenever we mention maps, we get lots of clicks. Hence, we’re happy to commend the following London map sites to you, as a source of unusual Christmas presents.
Triboluminescence Triboluminescence is an optical phenomenon in which light is generated through the breaking of chemical bonds in a material when it is pulled apart, ripped, scratched, crushed, or rubbed (see tribology). The phenomenon is not fully understood, but appears to be caused by the separation and reunification of electrical charges. The term comes from the Greek τρίβειν ("to rub"; see tribology) and the Latin lumen (light). book2 Audio Trainer - Learn 50 Languages Online for Free Free language lessons in over 50 languages book2 contains 100 lessons that provide beginners with a basic vocabulary.

It’s Time To Increase The Size of the House It’s Time to Increase the Size of the House Sean Trende, Senior Columnist, Sabato's Crystal Ball March 6th, 2014 “Our founders put the first amendment first for a reason. National Geographic shares rich map content with the world via Google Maps Engine Posted by Frank Biasi, Director of Digital Development, National Geographic Maps Editor's note: Today’s guest blog is about the newly launched Google Maps Engine public data program, which lets organizations distribute their map content to consumers using Google’s cloud infrastructure. Frank Biasi, Director of Digital Development at National Geographic Maps, tells us how his organization is participating in the public data program and sharing over 500 maps to the world. Why are maps important for National Geographic? Founded in 1888, National Geographic Society aims to inspire people to care about the planet.
Time dilation Time dilation explains why two working clocks will report different times after different accelerations. For example, ISS astronauts return from missions having aged slightly less than they would have been if they had remained on Earth, and GPS satellites work because they adjust for similar bending of spacetime to coordinate with systems on Earth. An accurate clock at rest with respect to one observer may be measured to tick at a different rate when compared to a second observer's own equally accurate clocks. This effect arises neither from technical aspects of the clocks nor from the fact that signals need time to propagate, but from the nature of spacetime itself. Overview In theory, and to make a clearer example, time dilation could affect planned meetings for astronauts with advanced technologies and greater travel speeds.
Reading Comprehension Worksheets "Your reading comprehension materials are the best I've found on the web. They are so thorough and comprehensive! My students and I have learned a lot from them. Thanks so much!" -- Susan B., Carter, KY. 03/21/12 Like these materials? Log In Photo I began election night writing a column that started with words from an immigrant, my friend Lesley Goldwasser, who came to America from Zimbabwe in the 1980s. Surveying our political scene a few years ago, Lesley remarked to me: “You Americans kick around your country like it’s a football. But it’s not a football.
Why border lines drawn with a ruler in WW1 still rock the Middle East 13 December 2013Last updated at 19:25 ET By Tarek Osman (@TarekmOsman) Presenter: The Making of the Modern Arab World The original secret Sykes-Picot map of 1916: "A" would go to France, "B" to Britain. A map marked with crude chinagraph-pencil in the second decade of the 20th Century shows the ambition - and folly - of the 100-year old British-French plan that helped create the modern-day Middle East.
"Terminator" Self Healing Polymer Created in Spain 2inShare Scientists from CIDETEC Centre for Electrochemical Technologies in San Sebastian, Spain have created the world’s first self-healing polymer that can repair itself without any intervention. The scientists named the polymer material ‘Terminator’ in a tribute to the molten T-1000 robot developed by Skynet to be nearly indestructible. The material is composed of a poly (urea-urethane) elastomeric matrix, a network of complex molecular interactions that will spontaneously cross-link to “heal” any break. Here, the word “spontaneous” means that the material needs no outside intervention or catalyst to begin its healing process. The polymer displays Velcro-like adhesive behavior with an impressive 97 per cent healing efficiency in just two hours.
Video Lesson: Mr. Bean / the future Follow me on twitter This is a video lesson based around the video “Mr. Bean packs his suitcase” thanks to British Council for bringing it to my attention in their lesson plan on making predictions but I’ve adapted it for use in different ways with different levels. Stephen Colbert Is Your Moral Guide and Your Outrage. This Monologue Is for the Ages. The return of Stephen Colbert at his very best and most biting? This monologue, from the start of last night's Late Show on CBS, is a keeper. Colbert forensically unpicked the news that you've been too tired or too overwhelmed to process yourself. It was, in total, a brutal takedown of Donald Trump's first day in Washington, DC, and a warning cry for what lies ahead. Colbert lambasted Trump's potential picks for Cabinet posts, and his impersonation of Sarah Palin's folksy word salad was especially savage.
Hexagonal Map of London This map is taken from an book “The Unification of London: The Need and the Remedy” written by John Leighton and published in 1895. London is split up into neat hexagons, colour-coded according to their proximity to the centre of the metropolis (defined as St Paul’s Cathedral rather than the more normal Charing Cross.) The map is made available as part of the British Library‘s releases to Flickr’s Commons project – the UK’s top reference library donated over a million images to the project recently. You can see all the graphics from the book here and download the book itself as a PDF here. It looks like John Leighton was proposing a wayfinding system for London based on each area’s “zone colour”. Lamp posts would be used, with one handle always pointing to the north to orientate people, and colours, numbers and letters to show the zone.
1950s Radioactive Science Kit: Most Dangerous Toy Ever? Science kits these days don’t contain many items that you couldn’t already find around the house: salt, balloons, magnets and a few odds and ends. But kids who were lucky enough to have wealthy parents in the early 1950s had the unprecedented chance to play with uranium ore in this very cool science kit. The Gilbert U-238 Atomic Energy Lab was only sold from 1951 to 1952, and at the time its $50 price tag was too steep for many families. The kit came with four different types of uranium ore, a geiger counter, a miniature cloud chamber, an electroscope, a spinthariscope and an educational comic book called “Learn How Dagwood Splits the Atom!”
