Laser Crosswalk Saves Pedestrians From a Painful Death

Laser Crosswalk Saves Pedestrians From a Painful Death
When the light turns red, a huge laser wall projecting apparitions of crossing pedestrians spans across the crosswalk. The concept is designed to keep crossing pedestrians safe from any overzealous drivers who otherwise might have ran the red light. Link [via]

Coriolis-like effect found 184 years before Coriolis - physics-math - 14 January 2011 The cosmos loves irony. While trying to prove that the Earth is fixed in space, an Italian priest described something similar to the Coriolis effect – the slight deflection experienced by objects moving in a rotating frame of reference – nearly 200 years before mathematician Gustave Coriolis worked it out in 1835. In 1651, Giovanni Riccioli published 77 arguments against the idea that the apparent motions of the heavens were due to the Earth's rotation and orbit around the sun. These included claims that Hell would be in the wrong place, aesthetic concerns over proportion and harmony, and more scientific approaches. Now, Christopher Graney at Jefferson Community and Technical College in Louisville, Kentucky, has translated them from Latin, and discovered that Riccioli conjectured phenomena resembling the Coriolis effect (arxiv.org/abs/1012.3642). In reality, the Coriolis effect is subtle, noticeable mainly in large-scale systems such as weather patterns and ocean currents.

iPhone App Word Lens Instantly Translates Life Into Something Amazing A new app just hit the iTunes App Store with the slightly unassuming name "Word Lens." You may think it's got something to do with typography or photography...but you'd only be partly right. It also instantly translates Spanish to English. What the app does is take the image stream from the iPhone's camera, apply real-time image processing and pattern recognition tricks to it, and it then "plays" with any text it finds in the scene before displaying it on the iPhone's screen. Not impressed by the description? LED Lights Make Augmented Vision a Reality LED Lights Make Augmented Vision a Reality Okay, this is just freaky. We know LED lights are versatile enough to be used for practically anything, but LED contact lenses? Really?! Yes, as it turns out, really.

NASA's lasercom system aims to beam a HD video feed from Mars As cameras technology has allowed us to increase the resolution of the images we capture and video we watch, so has the bandwidth required to transfer that imagery. In space, the amount of data that can be sent is currently limited due to the radio frequency (RF) systems being relied upon. NASA is trying to fix that limitation by testing a new communications system called a Laser Communication Relay (LCR). LCR is a desirable replacement because the optical/laser communication system (lasercom) allows for much higher data transfer rates while retaining the same size, weight and power requirements of existing RF systems.

untitled WHY PEOPLE THINK COMPUTERS CAN'T Marvin Minsky, MIT First published in AI Magazine, vol. 3 no. 4, Fall 1982. Reprinted in Technology Review, Nov/Dec 1983, and in The Computer Culture, (Donnelly, Ed.) Associated Univ. Scientists discover snowflake identical to one which fell in 1963 Scientists were today able to dispel the age-old belief that no two snowflakes are the same, using state of the art microscopy and by catching flakes as they fell in specially designed equipment while sitting at a table outside a pub in Norwich. The team of researchers, backed by a £20m grant, were able to make an identical match to the famous Bentley flake, photographed 47 years ago by amateur snowflakeologist Wilson Bentley. ‘It’s one of the last remaining challenges known to science and we’ve cracked it at last,’ said lead researcher, Professor Kenneth Libbrecht. ‘The team will soon disband to pursue other major scientific challenges, such as the unresolved toast-butter conundrum, and whether or not my baldness makes me a better lover.’

Japan's quake updated to magnitude 9.0 Read more: "Special report: After Japan's megaquake" 0930 GMT, 12 March 2011 Sumit Paul-Choudhury, editor, newscientist.com There has been a massive explosion at the Fukushima-Daiichi nuclear power plant, raising fears of a radioactive meltdown. Several workers are believed to have been injured in the blast, which seems to have caused major structural damage to the plant. A state of nuclear emergency was declared at the plant yesterday as its operator, the Tokyo Electric Power Company, struggled to contain rising temperatures and pressures in the core of two reactors whose cooling systems failed after Friday's magnitude 9.0 earthquake.

Plug Cup – Single Plugging Cup for Tea and Coffee by Dong Hun Seo, Geun Hyuk Yoo, Ki Sang Yoon & Yune Jae Bang Single Cup Special Oh boy, this Plug Cup is going to make me lazybones. Ever since I’ve laid my eyes on it, I have wanted this concept to come to life. It’s perfect for this instant coffee and green tea glutton that I am. A simple 180° rotating 2-pin plug at the base of the cup hooks on to any power source; so imagine this hanging off the powerstrip where my computer plugs are hitched! HMZ-T1: Sony unveils world's first 3D head-mounted display that is as immersive as 'sitting in a cinema' The HMZ device enables the wearer to experience cinema-like viewing, equivalent to watching a 750-inch screen from 20 metres away By Graham Smith Updated: 12:17 GMT, 31 August 2011 Technology giant Sony has unveiled a head-mounted display that takes the wearer into a 3D cinema of videos, music and games. The HMZ personal 3D viewer is being targetted at people who prefer solitary entertainment rather than sitting in front of a television with family or friends. Resembling a futuristic visor, the £480 ($800) device is worn like a pair of chunky goggles and earphones in one.

Adventure Titles CERN: Light Speed May Have Been Exceeded By Subatomic Particle GENEVA — One of the very pillars of physics and Einstein's theory of relativity – that nothing can go faster than the speed of light – was rocked Thursday by new findings from one of the world's foremost laboratories. European researchers said they clocked an oddball type of subatomic particle called a neutrino going faster than the 186,282 miles per second that has long been considered the cosmic speed limit. The claim was met with skepticism, with one outside physicist calling it the equivalent of saying you have a flying carpet.

Why do we believe in electrons, but not in fairies? by Benjamin Kuipers No one has directly observed either electrons or fairies. Both of them are theoretical constructs, useful to explain observations that might be difficult to explain otherwise. The "theory of fairies" can actually explain more things than the "theory of electrons". So why do we believe in electrons, but not in fairies? Is the issue a political one, where the "electron" fans got the upper hand in the nineteenth century, so by the twentieth century the "fairy" fans were a scorned and persecuted minority?
