Bicyclists Get Hindsight with Cerevellum Device

first_imgThe Cerevellum gives cyclists a rear view of the road. A start-up company called Cerevellum is developing a cutting-edge bicycle computer that has a first-ever feature: hindsight. The device, also named Cerevellum, provides a digital view of the road to the cyclist’s back, eliminating the need for those clip-on mirrors that always fog up and need adjusting. The device slides onto a holder mounted in the center of the handle bars. The 3.5-inch LCD screen (320×240 pixels) provides standard readings such as speed, distance, and heart rate, and also has GPS features. But the most unique feature is the rear-view video, giving cyclists ´eyes in the back of their heads’ and making bike rides on busy streets safer.The Cerevellum has slots on the back where USB modules are inserted. Some of the modules include ´hindisight´ (the rear-view feature), GPS, and ‘flight-deck’, which may offer electronic gear-shifting in the future. The module set-up ensures that the Cerevellum device won’t become obsolete in a few years.The hindsight feature presents real-time video that isn´t affected by road vibrations or the cyclist´s position. For capturing video, a lens can be mounted either on the back of the seat post or on the end of a handlebar. The device is powered by a lithium-ion battery, which lasts for about four hours with the hindsight video, or 16 hours with the other features. It also has a 32MB RAM card that allows users to save their workout data and transfer to a PC. While it´s not available for sale yet, the company estimates that the main unit will cost about $300, with the modules ranging in price from $60 for the standard cyclometer module, $200 for GPS, and $800 for the power meter.The device was originally conceived by Evan Solida as an Industrial Design student at Purdue University, but expounded upon more in the past couple years. Solida and partner Craig Appaneal, the founders of Cerevellum, explain that they’ve finished the design process, and hope to exhibit the device at Interbike or Eurobike 2008.More information: www.cerevellum.comVia: Gizmodo Citation: Bicyclists Get Hindsight with Cerevellum Device (2007, December 17) retrieved 18 August 2019 from This document is subject to copyright.

Ten of the biggest science and technology stories of 2014 on Physorg

first_imgThis tiny slice of silicon, etched in Jelena Vuckovic’s lab at Stanford with a pattern that resembles a bar code, is one step on the way toward linking computer components with light instead of wires. Credit: Vuckovic Lab (—This past year was an exciting time for science researchers—new discoveries and advances were made and more was learned about space, sub-atomic physics, speeding up computers and historical accomplishments, to name just a few. Below, we highlight what we feel were ten of the biggest stories of the year: © 2014 , Nature Explore further Astronomer confirms a new “Super-Earth” planet , Nature Nanotechnology A radio-burst discovery deepened an astrophysics mystery—Scientists working at the Arecibo radio telescope in Puerto Rico reported in a paper published in The Astrophysical Journal, that they had recorded a split-second radio wave burst that appeared to come from deep in outer space. The discovery was the first to corroborate reports of similar bursts recorded by researchers at the Parkes radio telescope in Australia. Neither team has been able to identify the source of the bursts, but possibilities include: flares from magnetars, evaporating black holes or mergers of neutron stars. Researchers achieved ‘holy grail’ of battery design: A stable lithium anode—Last summer, researchers at Stanford announced that they had taken a big step toward the design of a pure lithium anode. As they noted in a paper published in Nature Nanotechnology, an anode of pure lithium would be a huge boost to battery efficiency. Lithium is believed to hold the greatest potential for reaching the “holy grail” of batteries, because of its light weight and high density. They suggest that some additional engineering and new electrolytes might make it possible to create a practical and stable lithium metal anode that could be used to power the next generation of rechargeable batteries. Quantum physics got less complicated—Just this past month, an international team of researchers working at the National University of Singapore reported that they had found evidence that wave-particle duality is actually the quantum uncertainty principle in disguise, reducing two mysteries to just one. In a paper published in Nature Communications, the team describes how they were able to prove that the two concepts were one and the same, and suggest their finding could lead to a deeper understanding of quantum physics and possibly new applications of wave-particle duality. The first possibly habitable Earth-sized planet was confirmed—Researchers working at NASA’s Kepler Space Telescope last spring reported sighting the first exoplanet roughly the size of the Earth, orbiting within what has become known as the “habitable zone” of another star—the sighting was subsequently verified by teams working at the Gemini and Keck Observatories. Because of its proximity to its star, the planet, dubbed Kepler-186f, could feasibly harbor water, the team explained in a paper published in the journal Science. The newly discovered planet is part of the Kepler-186 star system located in the constellation Cygnus. Scientists discover how to turn light into matter after 80-year quest—A small team of theoretical physicists working at Imperial College in London developed a method to test whether smashing two photons together to create an electron and positron will result in the formation of matter—thereby proving correct a theory first proposed back in 1934 by Breit and Wheeler. The team reported in a paper published in Nature Photonics that they developed the idea while chatting over coffee. They will be leaving it up to other researchers working at an accelerator to actually carry out the experiment to prove the idea sound once and for all. “Sailing stones” of Death Valley mystery solved as they were seen in action for the first time—After centuries of conjecture, a small team of researchers has solved the mystery of how the “sailing stones” move across the desert floor, leaving evidence trails behind them. As they describe in a paper published in the journal PLOS ONE, the researchers set up a camera at just the right time and fortuitously caught the action in progress. Turns out the stones were moved by ice that had formed from a thin layer of water on the desert floor and then by wind pushing the ice against them.To learn about other exciting news in science and technology, we have set up a page that allows for easy reading of all of the top stories of the past year. Superheavy element 117 was confirmed by a research team in Germany—The periodic table of elements grew bigger by one as an international team of researchers working at Germany’s GSI laboratory artificially created atoms of element 117 using an accelerator. The group published its findings in Physical Review Letters, outlining how they caused the atoms to come about and describing it as 40 percent heavier than lead. The new element will get a formal name only after formal review by the International Unions of Pure and Applied Physics and Chemistry. Engineers took a big step toward using light instead of wires inside of computers—A team working at Stanford designed and built a prism-like device able to split light into its separate colors and then to bend each of the different components at right angles. They described their “optical link” in a paper published in Scientific Reports. It is a very small slice of silicon etched with a specific pattern that looks a lot like a bar code. The team believes the device could lead to using optics rather than electricity to carry data around inside of a computer. Superconductivity achieved without the need for cooling——a team of researchers from across the globe working at the Max Planck Institute and the SLAC National Accelerator Laboratory, succeeded for the first time in achieving superconductivity in a material without having to cool it down first. As the group explained in a paper published in the journal Nature, they used short infrared laser pulses to cause a piece of ceramic to become superconductive, if only for a few millionths of a second. Excitingly, the team was able to offer a plausible explanation as to why it worked. Ancient Egyptians likely moved pyramid stones over wet sand—Physicists working at the University of Amsterdam and the FOM Foundation discovered through experimentation that ancient Egyptian workers likely added water to the sand over which sledges bearing heavy stones meant for use in the pyramids were pulled, to make it easier to slide. The team reported in a paper published in Physical Review Letters that using just the right amount of water in the mix would have reduced the number of men needed to pull the sledge by half. The idea was supported by a wall painting dating from that time showing water being added to sand just ahead of a pulled sledge. , Nature Photonicscenter_img This document is subject to copyright.

A Public School Makes the Case for Montessori for All

first_imgMore than a century old, Montessori education takes a holistic, child-centered approach to teaching and learning that researchers say is effective, but for decades these schools have largely been the domain of affluent, white families. Nationally, estimates suggest that between 80 to 90 percent of U.S. Montessori schools are private, and most are concentrated in urban or suburban enclaves—not communities like Latta, where the median income is $24,000. The five miles from Interstate 95 into Latta, South Carolina, amble past fireworks shops and stretches of farmland bordered by matchstick pines and interspersed with the occasional home. Railroad tracks and a lone post office mark the center of town, home to 1,300 people and one elementary school, one middle school, and one high school that serve students in a county nearly 100 miles wide. In many ways, Latta is no different from other communities scattered throughout the rural South: Jobs are limited, businesses are local, and residents know one another. But the opening of a Title I public Montessori school has put this small town at the forefront of a movement that is upending the status quo around access to progressive education. To an outsider, a Montessori classroom may seem chaotic, but every component—from the layout to the school schedule—is designed with specific purpose, emphasizes Angeline Lillard, a psychology professor at the University of Virginia who has conducted research on Montessori schools for the last 15 years.

The chasm in between

first_imgDwelling on the theme of personal divides, Indian Council for Cultural Relations is organising a play, Namaste, by Ila Arun. It is will be staged 29 July in the Capital. The play emphasises on the new world, where barriers our shrinking and traditions, values and religion are struggling to keep up with the new generation; a generation that is undecided about the path they want to follow. No surprises here! It inevitably creates a rift between the old and the emerging new. Elaborating upon this metamorphosis, the play discusses these sensitive issues and also takes you in the realm of the surreal and the psychic. Its a rollicking comedy with a contemplative twist, offering wholesome entertainment for a family.last_img

NEET 2018 Examinees raise voice against Bengali question paper

first_imgKolkata: Almost half of the total questions of National Eligibility cum Entrance Test (NEET) 2018, which were translated into Bengali, were either full of errors or there was ambiguity in the questions.NEET is the national level medical entrance examination. The exam has been conducted by the Central Board of Secondary Education (CBSE) across the country on Sunday. Over 59,000 candidates from Bengal appeared for the examination at 99 centres across the state. Also Read – Heavy rain hits traffic, flightsThe students who wrote their answer papers with Bengali as the medium, have become upset as there were errors or ambiguity in almost 50 percent of the questions. It was also alleged that in some cases, there was no proper Bengali translation. In another allegation, around 83 students out of 600 appearing for NEET at Kendriya Vidyalaya Cossipore received question paper one hour after the examination started, triggering chaos at the exam centre.The exam was conducted on three subjects – Biology, Physics and Chemistry. Biology carries 90 questions while Physics and Chemistry carry 45 questions each. There are 4 marks for each question, taking the total marks of the examination to 720. Also Read – Speeding Jaguar crashes into Merc, 2 B’deshi bystanders killedThe students from the state who failed to answer the questions properly after opting for Bengali as the medium, are confused over the basis they will be evaluated on, or whether the national level board that carries out the examination, will take the responsibility of the alleged mistakes. It can also be mentioned here that only around 3,000 medical aspirants from Bengal appeared for this year’s examination in vernacular, while in the previous year the number stood at 34,000. According to a revelation, around 97.48 percent of MBBS seats across the country had been bagged by the candidates, who appeared for NEET with English as the medium of examination, in 2017. Meanwhile, only 2.52 percent of medical seats were secured by candidates answering their paper in vernacular languages.In the previous year also, there was a furor over the standard of the question paper in most vernacular languages, with the medical aspirants from Bengal and from some other states alleging that their questions were much harder than the ones in English and Hindi.Initially, the Centre had tried to conduct the examination in English, Hindi and some other languages. It was stated that students opting for Bengali as the medium would not be able to compete in all India seats and they have to appear only for the state quota seats. As Bengali was opted out, the state government had urged the Centre to allow the students to appear for the examination in Bengali. The experts had also demanded that all the regional languages, including Bengali, must be treated at par with Hindi and English.Dr A K Maity, an expert in the field of medical education in the country, said: “The Centre has been trying to bulldoze the sentiments of Bengali medium students. The CBSE cannot shed their responsibility in this manner and it must look into the matter with utmost seriousness. The brilliant Bengali medium students will not be able become doctors if this continues. The Bengali medium schools will be on the verge of extinction.”last_img read more
