Nanoscale optical switch breaks miniaturization barrier An ultra-fast and ultra-small optical switch has been invented that could advance the day when photons replace electrons in the innards of consumer products ranging from cell phones to automobiles. The new optical device can turn on and off trillions of times per second. It consists of individual switches that are only one five-hundredths the width of a human hair (200 nanometers) in diameter. This size is much smaller than the current generation of optical switches and it easily breaks one of the major technical barriers to the spread of electronic devices that detect and control light: miniaturizing the size of ultrafast optical switches. The new device was developed by a team of scientists from Vanderbilt University, University of Alabama-Birmingham, and Los Alamos National Laboratory and is described in the Mar. 12 issue of the journal Nano Letters. The ultrafast switch is made out of an artificial material engineered to have properties that are not found in nature.

Here, he explains how a camera attached to his head allows him to hear colour. Until I was 11, I didn't know I could only see in shades of grey. When I was diagnosed with achromatopsia [a rare vision disorder], it was a bit of a shock but at least we knew what was wrong. When I was 16, I decided to study art. I was allowed to do the entire art course in greyscale - only using black and white. At university I went to a cybernetics lecture by Adam Montandon, a student from Plymouth University, and asked if we could create something so I could see colour. If we were all to hear the frequency of red, for example, we would hear a note that is in between F and F sharp. I started using it 24 hours a day, carrying it around in a backpack and feeling that the cybernetic device, the eyeborg, and my organism were completely connected.

Space Challenges Program | www.spaceedu.net Cooking For Engineers - Step by Step Recipes and Food for the Analytically Minded Beautiful Places to Read in London Word recently reached us that the imposing Freemason’s Hall has a library in its belly. And thus, we began the day climbing a monumental marble staircase towards our appointment to view a poem about William Blake, enclosed in a book ‘bound in masonic ritual’. Alas, whilst the location is most beauteous, the librarians helpful, and there are many eccentric volumes to peruse, as a specialist library this repository of secret knowledge proved ill-suited for idle pleasure reading. William Blake by James Thompson, at the Library and Museum of Freemasonry Having taken our fill of Masonic memorabilia, my companions departed for their afternoon labours and I found myself ambling alone across Lincoln’s Inn Fields towards the Hunterian Museum. Looking forward to reading within that wondrous deposit of medical oddities, I’d completely forgotten it was half term. Thrice thwarted, I found myself once again upon the High Street, when a friend’s recent suggestion sprang to mind.
Cladirile viitorului: Padurea urbana din China locuri de vizitat, locuri de vazut - deVizitat.com Cativa arhitecti chinezi au vrut sa deruleze un proiect ambitios in care sa imbine doua arte designul si arhitectura. Cladirea care pare construita dintr-o multime de farfurii suprapuse este de fapt un proiect imaginativ. Arhitectii de la MAD din Beijing au realizat proiectul de design al unei cladiri de 70 de etaje, cu o inaltime de 385 de metri, care sa aiba gradini, terase, piscine si copaci in birouri. Podelele sunt asezate strategic, in asa fel incat sa para ca plutesc. Se pare ca proiectul va fi construit pe o suprafata de 7700 m2, in Chonquing, China.

“Most obscene title of a peer-reviewed scientific article” – an amusing award for a serious academic paper | Research This post was contributed by Professor Jean-Marc Dewaele, from Birkbeck’s Department of Applied Linguistics and Communication. This post contains strong language. As an applied linguist and a multilingual I have always been interested in the communication of emotion in a person’s multiple languages. It seems that telling jokes in a foreign language, declaring love or promising something in a foreign language does not quite have the same resonance as it typically has in a native language (see also my taster lecture – contains strong language!). One particularly interesting area is how multilinguals swear. I remember how Livia, my trilingual daughter (English, Dutch, French as first languages), aged 7, playing with a Belgian bilingual boy (Dutch, French as first languages), who, when he heard she also had English as a first language, exclaimed that he knew English too, after which he uttered Fuck you! In 2010, I published a paper: ‘Christ fucking shit merde!’
Masdar City Masdar City will host the headquarters of the International Renewable Energy Agency (IRENA).[6][7] The city is designed to be a hub for cleantech companies. Its first tenant is the Masdar Institute of Science and Technology, which has been operating in the city since it moved into its campus in September 2010.[8][9][10] The city as a whole was originally intended to be completed by 2016 but due to the impact of the global financial crisis, the date has now been pushed back to between 2020 and 2025. Due to the limitations found during the initial implementation, the city is now aiming to be low carbon.[4][5] Design and intent[edit] Masdar City will be the latest of a small number of highly planned, specialized, research and technology-intensive municipalities that incorporate a living environment, similar to KAUST, Saudi Arabia or Tsukuba Science City, Japan. Architecture[edit] Masdar is a sustainable mixed-use development designed to be very friendly to pedestrians and cyclists.[22] [edit]
