Visitors, upon reading the confident-sounding interpretive signs describing arch formation, might be surprised to learn that the origin of these structures is not fully understood. In a recent paper in Nature Geoscience, researchers from the Czech Republic who ran some new lab experiments imply that prior theories are incomplete, if not wrong:Weathering and erosion of sandstone produces unique landforms such as arches, alcoves, pedestal rocks and pillars. Gravity-induced stresses have been assumed to not play a role in landform preservation and to instead increase weathering rates. Here we show that increased stress within a landform as a result of vertical loading reduces weathering and erosion rates, using laboratory experiments and numerical modelling. We find that when a cube of locked sand exposed to weathering and erosion processes is experimentally subjected to a sufficiently low vertical stress, the vertical sides of the cube progressively disintegrate into individual grains. As the cross-sectional area under the loading decreases, the vertical stress increases until a critical value is reached. At this threshold, fabric interlocking of sand grains causes the granular sediment to behave like a strong, rock-like material, and the remaining load-bearing pillar or pedestal landform is resistant to further erosion.The new theory is summarized in the BBC News. In addition, Smithsonian Magazine has an embedded video clip of the experiments.In the authors’ view, gravity is the arch-hero, not the arch-villain. The gravitational load causes a kind of self-organizing system: the sand grains lock together in the pillars, resisting erosion. Eventually, of course, erosion wins, and the structure falls. It’s not clear if they can generalize this process to all arches. They experimented with a particular sand in their home country. “Critically, the sandstone from Strelec doesn’t contain cementing minerals that help bind the sand particles together,” the Smithsonian article says. “Instead, the authors found that the stress put on the sandstone causes minerals to interlock and hold the rock together.” It sounds like this is the best-case scenario to test the idea, because cementing materials would presumably increase the resistance to erosion in the pillars. Whether this applies to the Entrada Sandstone in Arches National Park is not clear; it also would not seem to apply to granite arches, as pictured below.Mobius Arch (granite) by David CoppedgeWhatever its merits, this new theory turns the old one on its head: “We should not say erosion or weathering carved the forms, as it was the stress field which give the forms the shape,” lead author Jiri Bruthans asserts in the Smithsonian article. “Erosion processes are mere tools controlled by stress.” The BBC quotes Bruthans comparing the stress field to Michelangelo. “The stress field is the master sculptor – it tells the weather where to pick.”Not much is said in any of the articles about how long it takes for arches to form. The Smithsonian says:The Czech team wanted to take a different approach. While doing fieldwork in Strelec quarry in the Bohemian Cretaceous Basin, they noticed that small arches and pillars—only about 2 feet high at most—formed out of the sandstone over mere months or years, rather than the millennial time scales associated with large geologic architecture.The BBC News, though, without a reference, says “The process had proved difficult to study, because natural slabs of sandstone erode over millions of years.”Landscape Arch, by David CoppedgeCreationists like Michael Oard have shown how just a few centuries since the Flood are sufficient (Creation.com, 2010) to form arches. He quotes secular authors who estimate only tens of thousands of years, not millions, for their formation; in fact, Oard argues, too much time is problematic: the arches should be long gone after even tens of thousands of years. Dr. Andrew Snelling, creation geologist, agrees, discussing sandstone arches briefly in the latest Answers Research Journal from AiG (July 2014). “What the park rangers won’t tell you,” Snelling says, is that 43 sandstone arches have collapsed since 1970. “Their loss is a sober reminder how delicate—and recent—these formations are,” he ends, after providing a Flood model for their formation. “Rapid processes created them and are now destroying them.”The Nature Geoscience paper is not clear on timeframes, so it is not clear the new theory can speak to the age issue. For the huge arches that were not observed forming, one can only estimate, considering variables and unknowns. Did arches form under steady-state processes vs one-time processes (like the Flood)? What were historical rainfall and wind patterns? You can’t look at erosion in a desert today and simply assume it’s always been so slow. It’s possible, in fact, to calculate reasonable upper limits on age of arches by taking conservative erosion rates today, and seeing how far back they can be extrapolated. If those rule out the “millions of years” interpretation, they show old ages to be a philosophical bias, not a conclusion from the evidence.Two other conclusions can be drawn from this story, though. One is the use of arches for design inference. What’s the difference between Landscape Arch pictured above, and the St. Louis Arch? Clearly the former is natural, and the latter intelligently designed. Beyond intuition, how can we tell? Use of such pithy examples can help teachers convey the principles of intelligent design. (Note: Comparing stress fields to Michelangelo is a personification fallacy.)The other conclusion is that scientific theories are at best tentative, especially when they try to speak of the unobservable past. The new theory is partly empirical, because these scientists were able to reproduce some features in the lab. But can one really scale up a small lab model by several orders of magnitude? Other factors might intrude at that level. For what it’s worth, the new theory overturns decades of thought and assumption about how these beautiful structures form, reminding us that science is, at best, a fallible human enterprise. Remember this story when you read the authoritative-sounding National Park signs.
SINGAPORE Airlines says it will be a case of “watch this space’’ as it brings in the first of five new Airbus A380s next year sporting premium product that will improve on its already impressive new-generation business seats.The Singaporean carrier created waves for manufacturer Airbus when it decided not to renew the 10-year lease on its first Airbus A380. The announcement came as Malaysia Airlines revealed it was in discussions with airlines in the region about offloading its fleet of six A380s.SIA may also not renew four more leases due to end, although a decision on that has yet to be made.But Singapore Airlines (SIA) executive vice president commercial Mak Swee Wah says the days of the double-decker superjumbo are not over yet.“The A380 probably has its niche,’’ Mak told AIrlineRatings during the recent inaugural flight of the Capital Express linking Singapore, Canberra and Wellington. “It is still the relevant plane for those key city pairs were traffic is dense and so I think it’s question of when you want to expand there’s this constant debate over capacity versus frequency.“So I think … it will be relevant of our fleet but a lot more of the services will be run by twin-engine planes.’’Mak said the decision against renewing the first lease was a result of the airline’s assessment of the need for the plane.“At this point in time, with the new ones coming in, we think that we really don’t need to expand the fleet so that’s why we are letting the lease expire,’’ he said. “When the decision time for the next few comes along then we will make the same new evaluation and if we don’t need to expand then we will do the same.’’The SIA executive would not be drawn on what was planned for the new aircraft, other than to say it would be better than its latest generation business class product.“I will say watch this space when the time comes,’’ he said.Read our review of Singapore Airlines’ new business seat.Singapore prides itself on the low average age of its fleet and it has already taken the first 67 A350s set to form the backbone of its fleet. These include seven ultra-long-range versions of the A350-900 deigned to fly up to 19 hours on non-stop flights between Singapore and New York.The A350-900ULR includes a modified fuel system and aerodynamic improvements that allow it to carry more fuel with an increased maximum take-off weight (MTOW) on services to the US.Also on order are 30 Boeing 787-10s, which will be the mainstay of the airline’s medium-haul fleet and are due to start arriving in 2018. “So there are a lot of new aircraft coming in and as they come in then the older 777s. which used to be the core of our fleet, will then be retired,’’ Mak said.Although Boeing has approached the Singaporean carrier about its next generation of Boeing 777s, Mak said no decision had been made.The influx of new planes into the region has been one of the factors responsible for increased competition that has pushed down air fares and airline yields.Mak does not believe there will be any rationalisation of capacity in the near term and said expert commentary suggested the world economy would continue to languish for some time.“It’s hard to predict,’’ he said. “I think t for the moment there is still a lot of airplanes which have been ordered which will be coming into service.“That’s why we on SIA’s side – not just SIA but the rest of the group – we have to continue with our growth and expansion plan to make sure that we get our fair share of the action.’’Like everyone else in the Asia-Pacific, Mak sees China as the biggest growth area and says all four members of the SIA Group — Singapore Airlines, SilkAir, Scoot and Tigerair — have expanded their presence there.He also sees a role for the new Singapore-Canberra-Wellington service as alternate gateway for Chinese tourists. There were about 90 visitors from China on the inaugural Boeing 777-200 flight and Mak said Singapore would do its share to promote traffic from the huge market to Australasia.And despite some scepticism about the route from competitors, Mak said putting the cities together made sense, with residents in both cities excited about the service and the response so far “encouraging”. The airline hopes to turn the four-times weekly route into a daily service as part of an expansion in the South-West Pacific that has seen the number of weekly flights to the region grow in recent years from 100 to 156. “We certainly hope to make it a success, especially with the support of the authorities, of the airport, of the tourism bodies,’’ Mak said“Both (cities) are equally strong and we’ll see over time as the market grows, how we can expand this further.’’He agreed one advantage of the markets was their relative affluence and pointed to the the wide range of groups in both cities with reasons to travel.“There’s government, there’s academia, there’s business people and the more affluent leisure traveller,’’ he added. “And also I think we do want to let the rest of the world know that there are some hidden gems around. It doesn’t come top of mind when we do overseas tourists but I think we need to do some work to let people know there’s more to Australia and New Zealand than just traditional gateways.’’SIA is working on the route with alliance partners Virgin Australia, which is providing lounge facilities in Canberra, and Air New Zealand, which provides them in Wellington.Air New Zealand chief strategy, networks and alliance officer Stephen Jones described the new route as a great addition to the alliance.’’Air NZ has authorisation through its alliance to co-operate with SIA to Singapore but Mr Jones said this did not extend to passengers flying across the Tasman. “But passengers flying from New Zealand via Wellington over Canberra to Singapore and beyond will be included in our alliance and in our revenue share,’’ he said.Singapore and AirNZ now co-operate on twice daily services out of Auckland, daily out of Christchurch and the four times weekly Wellington service.Steve Creedy travelled to Singapore, Canberra and Wellington courtesy of Singapore Airlines.
Thirteen students of the Central University of Haryana (CUH) in Mahendergarh were suspended on Thursday for allegedly creating “hindrance in the smooth functioning of academic and administrative functioning of the university”. The suspended students, including 11 BTech students, and others have been on strike since the past 10 days against lack of infrastructure and staff in the School of Engineering and Technology.Misbehaviour alleged The suspension came a few hours after the agitating students — who were protesting against alleged misbehaviour by security guards with female students on Wednesday night — prevented Vice-Chancellor R.C. Kuhad from leaving the premises in his car. They claimed the security guards used force on Wednesday to disperse students, including women, who were holding a peaceful protest outside the university’s Academic Block. They added that the guards also tore posters, prompting hundreds of students to hold a protest all night. The agitating students alleged that varsity officials misbehaved with them on Thursday and locked the building from inside to prevent them from entering the premises to drink water and relieve themselves.‘Baseless claims’Dismissed as “baseless” the allegations of misbehaviour by the guards, CUH spokesperson Shailender Kumar accused the students of manhandling the V-C. He claimed CUH had agreed to meet their demands in a time-bound manner and a notice in this regard was already circulated on April 15. Lack of facilitiesThe students are on strike since April 9, alleging that two years after the School of Engineering and Technology was established in 2016, it still lacks minimum facilities like laboratories, building and regular staff. The School offers BTech in four disciplines. However, a student of BTech (electrical engineering) said promises made by the administration were hollow. “We want a letter signed by the V-C himself with a promise to meet all our demands in a time-bound manner. We believed the verbal assurances of the V-C last August but nothing happened. How can we believe the administration that laboratories will be ready in three months when construction of building is yet to start?” said the student. CUH Finance Officer Sanjeev Kumar said the university’s notice to meet the demands of students in a time-bound manner had the approval of the V-C and was signed by the Registrar. “It seems that some people are instigating the students. The students seemed satisfied after a marathon meeting with the V-C on Wednesday but were instigated into continuing the protest. They are coming up with new demands every other day,” said Mr. Kumar.He added that approval of the All-India Council for Technical Education (AICTE) was not required for BTech courses as the university was autonomous body and received grants from the University Grants Commission.
It’s one of those high energy days. You decide to prolong your workout, jog five km instead of the three you normally do before calling it a day. You are bathed in sweat and need a cool yet nutritional drink to supplement your effort on the rubber. But the moment you start considering your choices, you are stuck.While good old banana shake beckons, you remember reading a scientific study about low fat chocolate milk being the ideal post workout drink. Then you recall your personal trainer’s lecture on the benefits of whey milk. But wait a minute.Click here to EnlargeShouldn’t you replenish the minerals lost with sweat through an electrolyte-based drink? We help you sift though these options and make the right choice.When you exercise, your muscles break down to take a bigger and stronger form and sweat makes you lose body fluid.Workout drinks help replenish the energy levels and keep you going. While proteinrich drinks focus on building better muscles, electrolyte-based drinks provide the essential minerals lost in sweat. Deciding what you need is essential.Check your hydration levelsTypically, you are required to drink two cups of water before, during, and after a workout to maintain level of body fluid.This may vary depending upon various factors including the length and intensity of your workout. A good way to check your hydration levels can be monitoring the urine output. Light coloured, diluted urine indicates good hydration levels while dark coloured, concentrated urine points towards dehydration. Also, keep a check on the weight lost before and post workout.advertisementStudies have found that athletes who lose as little as two per cent of their body weight through sweating experience a drop in blood volume which causes the heart to work harder to circulate blood, leading to muscle cramps, dizziness, fatigue and heat stroke. However, be cautious not to overdo hydration as this can lead to hypernatremia, a condition which occurs due to excessive water intake and low sodium levels in the blood. Drink around two cups of water for every 450 gm lost.Sweating causes a loss of electrolyte such as calcium, chloride, magnesium, sodium and potassium which are essential for normal body functioning. Though intense training in the heat will cause a depletion of minerals, training in a cool room won’t cause much electrolyte loss.Chocolate milk is idealChocolate milk is an ideal post-exercise drink, say two recent studies done at the University of Texas. Researchers found that athletes who drank this put on more muscle and less fat, recorded better timing while working out and were in better physical shape than peers who consumed sports drinks that just contained carbohydrates and calorie-free health drinks. Cyclists exhibited more power and reduced their ride time by an average of six minutes when they consumed low-fat chocolate milk. They were also found to have twice the improvement in endurance, built more muscle and reduced fat compared to others.”You can’t depend upon just carbs or just proteins to replenish the body which is why having zero carbs protein supplement or having only high carb drink is not a good idea. Better go for ideal mix of the two,” says Snehswaran Reddy, HOD, physical education, Gems International. However, chocolate milk only provides calcium and sodium – just two of the four major electrolyte lost in sweat. But, as explained earlier, you are not going to miss them much because your body is not depleted of these minerals during regular workout routines. Only if you find yourself exercising in extreme conditions over long hours, sports drink with a good electrolyte balance can be an ideal option.Whey-based drinkMilk contains two primary proteins: casein and whey. Whey has about about 20 per cent of milk proteins and is a natural by-product of the cheesemaking process. Earlier, this liquid was discarded but today it’s a major ingredient of protein supplements used by iron-pumping body builders across the world. Besides whey protein powders, whey-based beverages are also being marketed as workout drinks. These offer a combination of electrolyte, making them a cross between protein drinks and waterbased sports drinks.However, whey is high on lactose so anyone with lactose intolerance can’t consume it. The carb to protein ratio in whey greatly skewed at 16: 1, so it can be termed more as an energy booster with electrolyte than a muscle-building drink.Chocolate milk: Regular vs low fatScientists believe there is something in naturally occurring combination of carbs and protein that makes chocolate milk a mighty potion. However, low fat chocolate milk does not contain the ideal carb to protein ratio of 4: 1 which is needed to replenish glycogen stores and to stimulate muscle growth.advertisementOn the other hand, regular chocolate milk fulfils this criterion – one cup contains 226 calories, 31.7 g carbs and 8.6 g protein. It also contains 154 mg sodium, 1.1 g dietary fibre and helps meet 25 per cent of your daily calcium need.Pick a sports drink with low carbsIf you are exercising at a high intensity for 60 minutes or more, grab a sports drink with electrolyte. However, make sure that the drink doesn’t contain more than 8 per cent of carbs as high amounts of carbs can cause slow absorption, nausea, cramps or diarrhoea. But a drink with 5 per cent or less sugar solution may not provide enough energy to help you go on for longer period of time. “Electral contains much wider range of minerals lost in sweat than any other sports drink available in the market,” says Sanjay Arora, a seasoned marathon runner.
Puel led Southampton to the League Cup final in February, but a 3-2 defeat to Manchester United ended his hopes of silverware and was followed by a woeful run of results in the run-in.Southampton won only one of their final eight league games, scoring just one goal in their last five home matches. They finished eighth in the table with their lowest points tally in four years.”Southampton Football Club can today confirm that it has terminated the contract of Claude Puel with immediate effect,” the club said in a statement.”Everyone at Southampton would like to express our thanks to Claude for his hard work and commitment this year.”Following the departure of Ronald Koeman to Everton, the 55-year-old Puel joined the club last June, after spending four years at French side Nice.The club had finished sixth under Koeman in 2015-16, but Puel’s league results were mixed throughout the campaign.He did enjoy success in the League Cup, however, eliminating Arsenal in the quarter-finals, before beating Liverpool home and away in the semi-final to get to Wembley.Their run was halted in the final, however, as United’s Zlatan Ibrahimovic scored twice, including an 87th-minute winner.”The highlight of the season was a memorable day at Wembley in the EFL Cup final, a day our fans will always treasure,” Southampton added in their statement.Former Southampton great Matt Le Tissier told Sky Sports that it was Puel’s failure to entertain fans that ultimately cost him his job.”I think the main sticking point was the lack of goals and the lack of entertaining football,” Le Tissier said.advertisement”No goals in the last five home games was a big factor. I am afraid that was what cost him his job.”There is a lot of sympathy when you look at the eighth-place finish and cup final. On paper, it doesn’t look a bad season, but if you have watched a lot of games this season, it has been a backward step.”The club said the search for a new manager was already underway and they were confident of finding the right fit for the club’s “long term vision”.Former Borussia Dortmund boss Thomas Tuchel was the early bookmakers’ favourite to replace Puel.

An aircraft of India’s Jet Airways lands during rain showers in Mumbai on September 20, 2017PUNIT PARANJPE/AFP/Getty ImagesTroubled carrier Jet Airways seems to be doing everything it can to come up with a plan that will avert its much-speculated collapse. And on Thursday, February 14, the airline approved a bailout plan, which will see its lenders becoming the largest shareholders in the company.Jet Airways said that its board has approved a rescue plan, through which a consortium of banks — led by the State Bank of India — will convert a part of their debt into equity. As per the plan, the banks will convert the debt at a price of Re 1, mandated by a circular of the Reserve Bank of India. In order to meet a funding gap of about Rs 8,500 crore, the airline said that it would allot 114 million shares to the banks, but did not reveal how much debt would be converted to equity or how fresh amounts would be raised.The bank-led resolution plan (BLRP) is “to meet a funding gap of nearly Rs 8,500 crore which is to be met by an appropriate mix of equity infusion, debt restructuring, sale/sale and leaseback/ refinancing,” Jet Airways said in a statement.The proposal seems to have brought a new ray to hope to many and an independent consultant told the Economic Times that this would be a good step for the airline. “Jet is saved. The government is really working to ensure the airline survives and 23,000 jobs are protected.”However, this plan will now have to receive the final seal of approval at the shareholders’ meet scheduled for February 21. The proposal will also require a nod from the Securities and Exchange Board of India and the Ministry of Civil Aviation.Meanwhile, experts in the know have said that the debt to equity conversion is one of the few steps that Jet is taking as part of its rescue plans. Later, it is likely that Etihad, which already owns a 24 percent stake in the carrier, will subscribe to new shares issued and increase its stake to about 45 percent, reported ET.Drop in Naresh Goyal’s stake in the airline With this, founder and promoter Naresh Goyal is set to lose control of Jet Airways as his stake is likely to drop from the current 51 percent to about 25 percent.Speaking of this drop, Santosh Hiredesai of SBI Caps said in a note thus: “Naresh Goyal’s share will come down to 25.5%, Etihad to 12% and lenders will have a majority stake of 50.1%. While this will effectively transfer control of the airline to lenders, the press release is silent on how much of the debt will be converted under the exercise, which remains a key unknown for now, and also who is to bring in potential equity funding that is required to sustain operations and deliver a turnaround.”Earlier, it was said that Goyal was not very keen on giving up his stake and had reportedly even turned to Mukesh Ambani and Ratan Tata for help. the Tata Group has shown an interest in bailing out Jet Airways, but it depended on Goyal and his willingness in giving up his controlling stake. ReutersJet’s fourth quarterly consecutive loss On February 14, the beleaguered airline also reported its fourth consecutive quarterly loss. The loss was recorded at Rs 588 crore for the quarter ended December 31. The carrier has been reeling under the pressures of high fuel cost and cutthroat competition and is also known to have delayed the salaries of its employees. And on Thursday, chief executive officer Vinay Dube thanked the employees for their work.”We are indebted to our employees who, despite our interim challenges, have worked tirelessly to ensure the highest levels of operational reliability and customer services for our guests, in line with our core values,” he said in a statement.
Do you forward a chain mail even though you know fully well that your action would not bring any promised luck? This is because you might consider the costs of ignoring rationality is low relative to the costs of ignoring intuition, suggests new research.The researchers found that detecting an irrational thought and correcting that error are two separate processes, not one as most dual-system cognitive models assume. This insight explains how people can detect irrational thought and choose not to correct it, a process described as ‘acquiescence’ in the study. Also Read – ‘Playing Jojo was emotionally exhausting’“Even when the conditions are all perfect for detecting an error, when people have the ability and motivation to be rational and when the context draws attention to the error, the magical intuition may still prevail,” said researcher Jane Risen from University of Chicago Booth School of Business in the US.Understanding how acquiescence unfolds in magical thinking, can help provide insight into how it is that people knowingly behave irrationally in many other areas of life, the study said.

For example, people may acquiesce if they can rationalise their intuition by thinking that a particular situation is special. Acquiescence may also be more likely if the costs of ignoring rationality are low relative to the costs of ignoring intuition, the researchers said.The findings will be published in an upcoming issue of the journal Psychological Review.
79 youth in Kashmir Valley have joined various terror outfits during this year, a figure which is 30 per cent higher than that of the previous year, Rajya Sabha was informed on Wednesday.Replying to a written question by BJP member Lal Sinh Vadodia, Minister of State for Home Haribhai Parathibhai Chaudhary said as per reports, 79 youths have joined militant ranks during 2015 (as on November 30) whereas 60 youths joined militant ranks during the corresponding period of 2014.There has been a growing concern within the security establishment about the sudden increase in disappearance of youths in Kashmir Valley this year and reports coming in suggest that they have joined various militant organisations, especially pro-Pakistan Hizbul Mujahideen led by Burhan Wani.The minister informed the Upper House that the terrorist activities in the Jammu and Kashmir were regularly being monitored and reviewed at various levels.

Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now In a townhall Q&A session on Facebook yesterday, Marc Zuckerberg answered a handful of user-posed questions, tackling the specific (his workout routine, what’s on his reading list, the average number of hours he clocks in at the office each week) as well as the more far-reaching (predictions for Facebook’s future, the future of AI and the importance of creating a connected world).Below are a few highlights from the session, which drew questions from Richard Branson and Arnold Schwarzenegger, among others.On his workout routineZuckerberg works out three times a week, usually first thing in the morning, and tries to take his dog for a run whenever he can, saying it makes for a “hilarious” scene because it’s “basically like seeing a mop run.”(Fun fact: This nugget of information comes courtesy of Arnold Schwarzenegger, who asked Zuckerberg to shut down the whole “but I’m too busy to work out” excuse millennials are apparently fond of throwing around. “Mark, I always tell people that nobody is too busy to exercise, especially if Popes and Presidents find time,” he wrote. “You’ve got to be one of the busiest guys on the planet, and younger generations can probably relate to you more than they can the Pope – so tell me how you find time to train and what is your regimen like?”)On his work scheduleWhile he’s only physically in the office 50 to 60 hours a week, Zuckerberg doesn’t unplug when he leaves the building. “If you count all the time I’m focused on our mission, that’s basically my whole life,” he wrote.Related: Surprise! Mark Zuckerberg Isn’t a Workaholic. Well, Not Exactly.On the benefits of a connected world Richard Branson was on hand to ask Zuckerberg about why he’s working to connect the entire global population to the internet.While there are tangible benefits – such as “access to education, health information, jobs and so on,” he wrote – Zuckerberg believes that connecting more people will lead to more innovation. “Think about how many brilliant entrepreneurs there are out there who have great ideas and the will to change the world, but just lack basic tools to do so today,” he wrote. “If you go by the population, almost two-thirds of these entrepreneurs don’t have Internet access today. Once they get connected, we may have three times as many good ideas and amazing new services built that will benefit everyone around the world.”On artificial intelligenceIf Facebook’s ability to recognize and tag individuals in photos freaks you out, you won’t like what’s coming. “Our goal is to build AI systems that are better than humans at our primary senses: vision, listening, etc.,” Zuckerberg wrote. “For vision, we’re building systems that can recognize everything that’s in an image or a video. This includes people, objects, scenes, etc. These systems need to understand the context of the images and videos as well as whatever is in them.”On virtual realityLast year, Facebook acquired Oculus for $2 billion. So what are Zuckerberg’s plans for the company? In part, Zuckerberg says we can expect to see the social network use virtual reality to enhance online communication: “Just like we capture photos and videos today and then share them on the internet to let others experience them too, we’ll be able to capture whole 3D scenes and create new environments and then share those with people as well. It will be pretty wild.”Related: Mark Zuckerberg: I Would Only Hire Someone to Work For Me If I Would Work For ThemOn telepathyWhen asked “whats going on with facebook in the future?” Zuckerberg again focused on new methods of communication, this time going beyond advances in VR.If Facebook has anything to do with it, in the future we will be able to communicate telepathically. According to Zuckerberg, it’s the next natural advancement once swapping virtual reality experiences with one another becomes mainstream. “After that, we’ll have the power to share our full sensory and emotional experience with people whenever we’d like,” he wrote. “One day, I believe we’ll be able to send full rich thoughts to each other directly using technology. You’ll just be able to think of something and your friends will immediately be able to experience it too if you’d like. This would be the ultimate communication technology.”On pokingWhy’d he come up with the now defunct feature? “It seemed like a good idea at the time.”You can find Zuckerberg’s entire townhall session here, including answers to questions from Shakira, Arianna Huffington and Stephen Hawking.
