Citation: Virtual Worlds May Be the Future Setting of Scientific Collaboration (2009, August 4) retrieved 18 August 2019 from https://phys.org/news/2009-08-virtual-worlds-future-scientific-collaboration.html “The slow adoption of these virtual reality technologies by the academic (or any other professional) community is probably largely due to a widely held misperception that this is ‘just games,’” Djorgovski said. “This is incorrect; while these technologies got developed largely by the gaming industry, and there is certainly a lot of gaming going on, virtual worlds are something bigger: a general platform for all kinds of activities, ranging from entertainment to purely professional. Just like the Web itself.” As MICA’s founders explain in a recent published paper, MICA is currently based in Second Life where participants use avatars to explore and interact with their surroundings, and will expand to other virtual worlds when appropriate. As of this past March, MICA had about 40 professional members and 100 members of the general public interested in learning about science, specifically astronomy. MICA is also establishing collaborative partnerships with the IT industry, including Microsoft and IBM, and plans to further develop industrial partnerships. “Virtual worlds are already a very fruitful arena for research in social sciences and humanities, including sociology, economics, psychology, etc.,” lead author George Djorgovski told PhysOrg.com. “They are already a superb educational and outreach platform, and should be used much more. We are trying to find out what else we can do with these technologies in the natural sciences, such as physics and astronomy.”In addition to getting people together in a free and convenient way, virtual worlds can offer new possibilities for scientific visualization or “visual analytics.” As data sets become larger and more complex, visualization can help researchers better understand different phenomena. Virtual worlds not only offer visualization, but also enable researchers to become immersed in data and simulations, which may help scientists think differently about data and patterns. Multi-dimensional data visualization can provide further advantages for certain types of data. The researchers found that they can encode data in spaces with up to 12 dimensions, although they run into the challenge of getting the human mind to easily grasp the encoded content. Explore further Djorgovski and his coauthors see virtual reality as the next step in the continuing evolution of the ways we use information and computation technology to interact with each other. They predict that, in the future, virtual reality will become more synthesized with the Web by serving as an interface and replacing today’s browsers. “One can think of immersive virtual reality as the next generation browser technology, which will be as qualitatively different from the current, flat desktop and web page paradigm, as the current browsers were different from the older, terminal screen and file directory paradigm for information display and access,” the authors explained in their overview.As Djorgovski added, immersive virtual reality (including virtual worlds) seems currently to be roughly at a stage of development of the Web in 1992, with limited reach but huge growth potential. “Possibly the overall societal impact of these technologies would be as big as that of the Web itself – or even bigger,” he said.One part of this possible next generation application of virtual reality is an open source program called “OpenSimulator” (or “OpenSim”), which enables users to create their own 3D virtual worlds and applications. The authors predict that the synthesis of the Web and virtual reality could involve individuals managing their own virtual reality environment in a way that is analogous to hosting and managing websites today. In the meantime, MICA’s virtual events for a general audience include a series of popular talks called “Dr. Knop talks astronomy” and weekly “Ask an Astronomer” sessions. The authors have also started experimenting with regular student classes, graduate seminars, class discussions, and hybrids in which students read lecture materials on their own and use class time for an open discussion in the virtual world setting. They also plan to conduct a series of international “summer schools” on topics including numerical stellar dynamics, computational science and others, in an immersive and interactive virtual world venue.More information: MICA Website: www.mica-vw.org/S.

New Way of Measuring ‘Reality’ of Virtual Worlds Could Lead To Better Business Tools (PhysOrg.com) — Normally, virtual worlds are the setting of many online games and entertainment applications, but now they’re becoming a place for scientific collaboration and outreach, as well. A team of scientists from the California Institute of Technology, Princeton, Drexel University, and the Massachusetts Institute of Technology have formed the first professional scientific organization based entirely in virtual worlds. Called the Meta Institute for Computational Astrophysics (MICA), the organization conducts professional seminars and popular lectures, among other events, for its growing membership.

(PhysOrg.com) — “One of the many reasons people study ultracold gases is for their potential as model quantum systems,” Deborah Jin tells PhysOrg.com. “There is a need to model quantum many-body systems because a lot of important physics – from condensed matter and material physics to nuclear and particle physics – increasingly require an understanding of complicated quantum behavior. Ultracold gases can possible provide that through models we can interact with, helping to close the gap between what we can describe theoretically and what actually happens.” Copyright 2010 PhysOrg.com.

Jin, along with fellow NIST scientist Jun Ye and their team of researchers have prepared a molecular quantum gas in a single hyperfine state, resulting in control over the final remaining degree of freedom needed to control all aspects of molecules in an ultracold gas. The group’s work has been published in Physical Review Letters: “Controlling the Hyperfine State of Rovibronic Ground-State Polar Molecules.”“To see quantum behavior, we want all the particles to be indistinguishable from each other,” Jin explains. “All of the atoms or molecules in the gas have to be in exactly the same internal state.” She says that some ultracold gases have approached this point, but the one thing lacking has been control over the hyperfine state, which accounts for nuclear spin inside the atoms that make up the molecules that form the gas. “It seems that this degree of freedom is not worth worrying about, and in most classical physics and in chemistry, it really doesn’t matter, since the amount of energy is so small. But for quantum behavior, even that should be lined up. We describe how to identify and control what’s going on inside the nucleus,” Jin says.In order to create a situation allowing control over the hyperfine state, the group at JILA first used improved spectroscopy techniques to identify the state of the molecules. The state of the molecules needed to be identified, and the molecules needed to be brought to their ground state. In order to do this, the group built on techniques used for hotter samples. “It’s hard to change nuclear spin, since it is weakly interacting,” Jin says. “But it is easy to drive from non-rotating to rotating, and there is a weak coupling. We use a microwave field to drive rotation, and then bring the molecule back to non-rotating, but with a different nuclear spin.”“With control of this final degree of freedom, we can say that we truly do have a quantum gas,” Jin insists. “If we can get the gas a little colder, we should really be able to see the quantum mechanics involved.” Before that point is reached, however, there are some steps that need to be taken. “We need a greater understanding of ultracold chemistry first, and we need to study how to ‘turn on’ the polar part of the molecules we use, figuring out what happen when we align them using the proper field,” Jin says.“We are making rapid progress, though,” she continues. “We are quite close, closer than ever before, to being able to model interesting quantum behavior with ultracold polar molecules. And once we do that, there is a whole new world of science ahead.”

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. (Phys.org)—A team of engineers at Purdue University has succeeded in building a time cloak based on dual laser broadcast communications channels sent through a common medium. In their paper published in the journal Optica, the team describes how they improved on earlier work to create a time cloak that allows for hiding data in high-speed data communications. ‘Cloaking’ device uses ordinary lenses to hide objects across continuous range of angles Most people have heard of a cloaking device, it’s a means of covering an object so as to prevent it from being seen. Less well known are time cloaks, which hide events rather than objects. A team of engineers at Purdue has been investigating this idea and last year, came up with a way to transfer data that was hidden, by time cloaking, across a communications channel. The drawback was that the approach was too successful, the data couldn’t be read by anyone. Now, the team has improved their cloaking approach to the extent that it allows data to be time cloaked for transmission, and uncloaked by those that know how, all while keeping the data cloaked (hidden) from everyone else’s perspective.A time cloak works by masking evidence of the existence of an event. One way to do it is to control the flow of photons streaming from a laser. The idea is to insert data into a stream in a way that appears to the casual observer as steady, but in fact was interrupted to allow for data insertion, then resumed. Only those in the know beforehand would realize that data had ever existed in the stream. But, the catch is that those in the know must have a means for extracting that data—that’s what the team at Purdue has now developed.The device works by means of two communications channels based on lasers with two different frequencies. One of the frequencies is normal, in that it’s not time cloaked. The second is time cloaked and thus events that occur in it are hidden, except from those that know how to access them. The light from both channels travels down the same length of fiber cable, allowing someone who knows about the cloaked channel to tap in to the correct one to gain access to the data it holds. This approach allows those in the know to access hidden data, and also to fend off interlopers hoping to disrupt the communications.Besides being useful as a security measure, the researchers believe their technique could help improve high-speed data transmissions in the near future. © 2014 Tech Xplore Basic outline of temporal cloak.

Experiments thus far have demonstrated temporal cloaking of nonlinear interactions and high-speed optical data. Here we report a temporal cloak with the new capability not only to hide optical data, but also to concurrently transmit it along another wavelength channel for subsequent readout, masking the information from one observer while directing it to another. Additionally, the cloak succeeds in passing modulated data unscathed through a scrambling event, providing a new form of tampering resistance. Both examples launch a paradigm shift in temporal cloaking: instead of using time cloaks primarily to disrupt communication, we show how they can also improve data transmission, in turn greatly widening the range of possible applications in telecommunications.
More information: Defining the epoch we live in, Science 3 April 2015: Vol. 348 no. 6230 pp. 38-39 DOI: 10.1126/science.aaa7297 AbstractHuman alterations of Earth’s environments are pervasive. Visible changes include the built environment, conversion of forests and grasslands to agriculture, algal blooms, smog, and the siltation of dams and estuaries. Less obvious transformations include increases in ozone, carbon dioxide (CO2), and methane (CH4) in the atmosphere, and ocean acidification. Motivated by the pervasiveness of these alterations, Crutzen and Stoermer argued in 2000 that we live in the “Anthropocene,” a time in which humans have replaced nature as the dominant environmental force on Earth (1). Many of these wide-ranging changes first emerged during the past 200 years and accelerated rapidly in the 20th century (2). Yet, a focus on the most recent changes risks overlooking pervasive human transformations of Earth’s surface for thousands of years, with profound effects on the atmosphere, climate, and biodiversity. Explore further Humans have had a major impact on planet Earth, there is no debating that. But have our efforts resulted in an un-reversible geologic impact? And if so, when exactly did it happen? That is what climatologists, geologists and other scientists have been debating for the past several years. Back in 2000 Paul Crutzen and Eugene Stoermer published a paper igniting the debate by coining the word Anthropocene to describe what they felt was the current epoch—where humans are the driving force, instead of nature. They suggested its start was the 1700’s because that was when the industrial revolution got going.Over the past fifteen years, many others have published papers offering their ideas on when the Anthropocene got its start, with some debating whether it ever really did. In this new paper, the authors suggest that if a start date is to be identified it should take into account the massive changes wrought by cutting down forests and the start of agriculture, which they say pushes the date back 11,000 years, or perhaps to the time when humans began wiping out other large animals such as the woolly mammoth, around 50,000 years ago.The thing that is making it difficult to settle the matter is the absence of a clearly identifiable marker, known as a golden spike, e.g., the comet that killed off the dinosaurs. Some have suggested that scientists finding traces of radiation worldwide from nuclear tests is such a marker, while others point to the finding of carbon ash (due to burning coal) in soils.Official designations are carried out by the International Union of Geological Sciences, which has not changed its stance that we are still living in the Holocene epoch, which began 11,700 years ago—after the last ice age receded. Debate on the topic will likely proceed and there is no guarantee that a consensus will be reached, and that is why the authors of this new paper suggest that perhaps the word Anthropocene be changed to anthropocene (lower case) and be used to designate an idea rather than a formal epoch.

The main culprit is carbon dioxide, but there are other greenhouse gases making their way into the atmosphere, as well—one of them is methane. Humans produce methane naturally, via flatulence, as do animals. It also results from production of rice and other crops, and released it during oil extraction. To combat global warming, we stop emitting methane, or find a way to remove it. In this new effort, the researchers report a natural way to remove methane from the air by supporting a type of bacteria that oxidizes it.Scientists have suspected for many years that one or more types of bacteria oxidize methane because testing has shown that methane levels drop in places where there is soil present.The researchers report that they have isolated a type of bacteria that lives in soil and oxidizes methane: Methylocapsa gorgona. It is very common and is found all around the globe. It can also live on very low concentrations of the gas. On the downside, the researchers found that it is also quite fragile, and activities like farming can kill it.The researchers suggest that M. gorgona could possibly be an effective methane sink if used properly. They also acknowledge that creative ideas are required before such applications could come to fruition. They go so far as to suggest the bacteria might be genetically altered to force it to consume more methane. But in the meantime, the discovery could lead to changes in farming practices that prevent the destruction of the bacteria, allowing vast stretches of land to once again remove methane from the air.

How paradoxical are our lives are! We live in a conservative society in a modern country. There are some who dare to experiment with unconventional things while there are others who prefer to remain behind closed doors.Madhav Mehta belongs to the former category. This 22-year-old theatre artist has come out with his directorial debut, titled Kasturba Panda ki Pantie. The 75 minute production is presented by Epic Shit Entertainment.The play is the story of Kasturba, the frustrated wife of a failed businessman named Ranjan Panda. Since his business isn’t doing good, he plans to rent out parts of his Sundar Nagar home but does not find too many takers. One day Kasturba gets to know that superstar Salman Khan will be coming to the famous Sundar Nagar Diwali mela. Kasturba, being a huge Sallu fan, rushes to the mela to catch a glimpse of the superstar. As she stretches on her tiptoes to get a good view of the man, her petticoat and panties slip off. And all of a sudden, the number of parties interested in taking up Ranjan’s rental offer skyrockets. Also Read – ‘Playing Jojo was emotionally exhausting’The play is a one-man show, played by Farhad Colabavala who dresses as all the different characters in the play. It is a narration followed by dialogue. ‘It’s a solo performance by Farhad which explores the state of a modern, conservative, married Indian woman in Delhi. I have known Farhad for four years and we have done theatre together. I adapted this play only keeping him in mind,’ said Madhav.’Doing this one-man show has been challenging, but overall a very enriching experience. Switching between characters without losing the flow has been a learning experience, which has helped me evolve as an actor. It’s been a really fun process, working with such a great team of people backed by an absolutely hilarious script,’ said Farhad. Also Read – Leslie doing new comedy special with NetflixMadhav says his play is not meant for the general theatregoers. ‘To begin with, the story is not in your usual play format. This format requires the play to be much tighter, with acting at a different plane to hold the attention of the audience. It belongs to an adult comedy genre and also caters to feminist thoughts at the same time,’ he said.And that must be noted.DETAILAt: Akshara Theatre, Baba Kharak Singh Marg, Connaught Place When: 22-24 February Timings: 4 pm and 8 pm Tickets: Rs 400

Inspite of all the ups and downs we faced throughout years, we are left with no regrets. I just wish the journey goes on for years after. How would you guys define your musical philosophy?Practically we don’t have any philosophy. Called for music we don’t make music for public. We make music for ourself and hope that the public likes it. We just have to be happy and than only we can be true and can make really good music which everyone will accept.In our country how easy or difficult it is to make a mark in music?Well, according to me it is as easyor as difficult as you make it to be. In India a lot of things have changed. More people can come up with their talent. There are a lot new festivals which can help you showcase your talent. You have to be ready for a long process. Nothing is spontaneous. What/ Who would you take as your greatest inspiration?Calling it inspiration, I cannot take a single name. There are a lot of people whom I met throughout the journey of life. All of them inspires me in one way or another. Any act of kindness or cruelty by anyone do leaves a vital mark in my life. What lies next in the pipeline?There are no plans yet. Tandanu was a very big project which left us with a very tight schedule. We haven’t planned anything for future now.

Sudeshna Sarkar was taken to a hospital in Ranigunge along with two others while the doctors pronounced her brought dead. Other three members of the Sarkar family have been undergoing treatment in an Asansol hospital.Police have seized both the vehicles while the driver of the dumber has fled the spot immediately after the accident. A probe has been initiated by the police in this regard.
Kolkata: West Bengal Chief Minister Mamata Banerjee on Tuesday greeted Shiv Sena chief Uddhav Thackeray on the occasion of the party’s 52nd Foundation Day. “Heartiest greetings to Uddhav Thackeray Ji and all Shiv Sena workers on the 52nd Foundation Day of their party,” Banerjee tweeted. Banerjee, who is playing an active role in promoting the idea of a federal front together with regional party leaders to counter the Bharatiya Janata Party (BJP) in the 2019 general elections, has spoken positively of the Maharashtra-based party’s decision to contest all future elections independently. In spite of being the BJP’s ally in both Maharashtra and at the Centre, the Shiv Sena and the saffron outfit have been at loggerheads for several months. It has also backed Delhi Chief Minister Arvind Kejriwal’s ongoing sit-in protest.
