Paredes têm ouvidos; e podem contar o que ouviram
Informática Redação do Site Inovação Tecnológica - 09/12/2014 Como as vibrações detectadas na superfície dos objetos estão diretamente relacionadas às ondas sonoras no ambiente, é possível reconstruir a informação de áudio original.[Imagem: Zhaoyang Wang et al. - 10.1117/1.OE.53.11.110502] Recuperação do som ambiente Parece que não são só as paredes que têm ouvidos: qualquer objeto no ambiente de fato ouve tudo o que se fala ao redor deles. E, pior do que isso, eles também têm bocas, e podem contar aos outros o que você está falando. Pesquisadores demonstraram uma técnica óptica simples por meio da qual "informações de áudio" - sons - podem ser extraídas a partir de gravações de vídeo feitas em um ambiente. A técnica utiliza um processo de correspondência de imagens que se fundamenta na detecção das vibrações imperceptíveis que as ondas sonoras causam nos objetos.

HOW TO CHEAT AT EVERYTHING
Over lunch with Simon Lovell, a fascinating former card shark, Allison Schrager learns all sorts of things about how swindlers operate ... Special to MORE INTELLIGENT LIFE "I can spot someone's weakness a mile away. In any room I can pick out the best target," says Simon Lovell, reformed con artist and famed magician, when asked over lunch about the root of his talents. "Take that woman over there." "Or that man over there, over-dressed, too neat, over-confident, thinks he is too smart to be taken." "But ultimately, anyone can be conned, if you have the balls to do it." Simon Lovell should know. Presently, instead of subjecting people to cons, Mr Lovell stars in a one-man off-Broadway show, "Strange and Unusual Hobbies". "I could sell shit at an anti-scat party," he says, "you have to figure out someone's wants and needs and convince them what you have will fill their emotional void." It requires avid study of psychology and body language. Con men tend to be excellent conversationalists.

Richard Candida Smith Intellectual History of the United States since 1865 - In this course we will be discussing key developments in U.S. thought since the middle of the nineteenth century, roughly beginning with the reception of Darwin. The broader story told in the class weaves together in the history of science and engineering, the arts and popular culture, philosophy, and education. read more Gail S. Energy and Environment - This course provides undergraduates and graduates with an introduction to issues of physical building performance including building thermodynamics, daylighting, and solar control. Jonathan S. Prison - Taking a broad interdisciplinary approach, this course embraces the longue duree of critical prison studies, questioning the shadows of normality that cloak mass incarceration both across the globe and, more particularly, in the contemporary United States. read more Asian American Studies 132AC, 001 - Spring 2014 Hatem A Bazian Kevin E.

"ET Technology Could Appear as Natural Objects in the Universe"
According to the British physicist Stephen Wolfram, intelligent life is inevitable. But there is a hitch. Although intelligent life is inevitable, we will never find it -at least not by looking out in the Milky Way. According to Wolfram, if someone beamed our own 21st-century communication signals at us from space we would be hard pressed determining whether they were artificial or natural. ET artifacts coordinated by computers would look far more like a natural onject. If Wolfram is right and ETs are out there but we will not be able to recognize them - either in their communications or their artifacts - then of course they could be here in the Solar System and we would not have noticed. Wolfram thinks ETs will not want to travel to Earth - or anywhere else for that matter. The existence of this computational universe is the crucial thing. Everything is generated by computer program,"and that includes you and me," says Wolfram. Casey Kazan via ] M.
Essas são as 9 descobertas mais alucinantes da física
O estudo da física é o estudo do universo e, mais especificamente, de como o universo funciona. É, sem dúvida, um dos ramos mais interessantes da ciência, porque o universo, como se vê, é muito mais complicado do que parece ser superficialmente. O mundo funciona de algumas maneiras realmente estranhas. Aqui estão 9 das coisas mais incríveis que os físicos descobriram sobre o nosso universo: 09. De acordo com a Teoria da Relatividade Especial de Einstein, a velocidade da luz no vácuo nunca pode variar – ela é de quase 300 mil km/s. Mas a ideia vale para velocidades maiores, e é aí que as coisas ficam interessantes. Talvez mais incrível do que isso é o fato de que se você pudesse atingir a velocidade da luz, o tempo simplesmente pararia para você. 08. Tudo bem, então nós acabamos concordando que nada pode se mover mais rápido que a velocidade da luz, certo? A mecânica quântica, em essência, é o estudo da física em uma escala microscópica, como o comportamento das partículas subatômicas.

12 Deadly Grammatical Errors Startups Must Avoid
If you like stories about the intersection of technology and language, then be sure to check out our Top 5 TEDxTeen Talks. Can the difference between "it's" and "its" actually affect the fortunes of a technology startup? You might be surprised. If you're working with a startup, odds are you're wearing a half-dozen hats and doing too much with too little. Often, this means that founders are writing their own website copy, press releases and blog posts. Everyone Makes Mistakes Two things before we get started. Secondly, this shouldn't be taken as a claim that any writing is completely error-free. The Dirty Dozen 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. To further confuse things, because English is a cruel and unforgiving language, there's complimentary and complementary. 12. Finally, a bonus entry for leetspeak or text-speak. Ain't You Going to Mention Ain't? Has anyone ever told you that ain't isn't a word? This list represents some errors that are common enough to be noteworthy.
