(Visited 446 times, 1 visits today)FacebookTwitterPinterestSave分享0 We hear it all the time; 99% of scientists agree. All it takes, though, is one overlooked fact to tumble a consensus.Occasionally we take a look at matters other than creation and evolution, when they are instructive about the scientific process. The scientific consensus on climate change (previously known as “global warming”) is a case in point. Scientists have been so dogmatic about it they have convinced most major world governments to enact draconian measures to counteract it. Climate has changed drastically in the past before humans evolved, they will admit, but they insist that the current climate excursion was caused by people trying to increase their happiness and reduce their suffering. News about global warming often includes denunciations of President Donald Trump for pulling America out of the Paris Climate Accords.We don’t quote climate “denialists” to get into the mud on this issue. We just look at the secular news itself, which is almost uniformly on the side of the climate consensus, and ask questions (see this list for previous entries). We pass over the ridiculous stories about what’s coming with global warming, like this headline on Phys.org, “Competition between males improves resilience against climate change.” Claims like that nobody could ever know for sure. Instead, we focus on the epistemology of the consensus: how do they know what they claim to know about human culpability for a warming climate? Did the consensus take the following factors into account?These ‘Dirty’ Thunderstorms Fill Sky with As Much Smoke As Volcanic Eruption (Live Science). Big volcanic eruptions, it is well known, can alter the climate. A well-known case was the Mt. Pinatubo eruption that reduced global temperatures for a time by 0.9° F in 1991. This article says that pyrocumulonimbus storms (pyroCb’s), or “dirty thunderstorms” fed by ash from wildfires, can put as much carbon smoke into the atmosphere as a volcano. “While such major volcanic events are sporadic, Peterson said, pyroCb events occur every year,” the article ends. “But scientists have not studied these storms enough to understand their potential impact on the climate.” Since wildfires are common, and have occurred long before man started burning coal or oil, would climate models produce different conclusions if pyroCbs were taken into account?Smoke from a relatively small wildfire.Tiny particles high up in the sky give insight into climate change (Phys.org). Black carbon (BC) can reflect incoming solar heat back into space, this article says. So can the clouds that form around the particles. Atmospheric particles, or aerosols, are thought to be the second or third most important factor after carbon dioxide. But do scientists understand its contribution? Note the uncertainty in this quote regarding a substantial contributor to climate change (which would seem to lower temperatures rather than raise them).Aerosols, tiny particles that are suspended in the atmosphere, contribute significantly towards climate change. However, despite their consequential role, aerosol interactions aren’t very well understood.The authors say that particles can last for years and influence regions far from cities with their pollution. The concentration of these particles over the Amazon Basin was higher than expected. Does this give anyone confidence in climate models, with their dire predictions of temperature changes a century away, specified in tenths of a degree? Yet those are the models used to scare politicians into taking drastic action.Microbes eat rocks and leave carbon dioxide (Science Magazine). This news item reveals that geologists and climatologists were wrong about silicate rocks acting as a carbon sink to counterbalance the outgassing of volcanoes. Microbes in the silicates can actually “eat” the rocks and release much of that carbon back into the atmosphere as CO2. A study of these rocks in Taiwan showed that “microbes oxidize roughly two-thirds of the petrogenic organic carbon there and that the rate of oxidation increases with the rate of erosion.”How does the Pacific Walker circulation respond to strong tropical volcanism? (Phys.org). Read this news item to get an idea of how complicated it is to tease out the significance of individual factors that might alter the climate. Severe volcanic eruptions (SVE’s), like the recent one in Bali, Indonesia, “can affect Earth’s climate.” But by how much? Trying to figure that out is complex, because a large eruption, which is unpredictable, can affect air currents in unexpected ways that are not well understood. Obviously humans are not responsible for what volcanoes do. Note, too, that SVEs tend to have a cooling effect. “The cooling effect from the SVEs is able to cool the entire tropics,” the article says, and yet the temperature anomalies that result are not uniform.Anthropogenic combustion iron as a complex climate forcer (Nature Communications). Even though this paper mentions a factor that might exacerbate warming, the key fact is that it was not taken into account before. “Our results demonstrate that anthropogenic combustion iron is a larger and more complex climate forcer than previously thought, and therefore plays a key role in the Earth system,” the authors say. This should lead thoughtful observers to ask what other factors have not been considered, that could be larger or smaller than previously thought?The Politics of Climate ChangeRepublicans more persuasive than scientists on climate change (Science Daily). This article, pretending to be an unbiased analysis of political attitudes about climate change, ends up as a partisan advocacy piece. The authors of a psychological survey at the University of Connecticut seem disturbed that Republicans who argue against anthropogenic climate change are more persuasive than the scientific consensus. But rather than see if Republican counter-arguments have merit, the authors delve into ways to package consensus arguments in more persuasive ways. They assume that Republicans are engaging in misinformation. “Citing Republican elites who endorse the scientific consensus on climate change may be the most effective way to persuade citizens that climate change is a real and important problem,” says Lyle Scruggs, a professor of political science at University of Connecticut. “That may be a step forward in reducing the partisan gap in public opinion on the subject.” Anyone smell partisanship in that comment?In closing, maybe it’s worth asking what the ruckus is about. Mike Wall wrote on Space.com, “Life on Venus? Why It’s Not an Absurd Thought.” Venus, we note, is a very warm planet. Astrobiologist David Grinspoon says that the atmosphere a few dozen miles up is pretty benign – if the Venusians can tolerate the sulfuric acid. So why worry? If climate change wipes out human society, some scientists, like the misanthrope Eric Pianka who wants to solve overpopulation of stupid people by releasing atmospheric ebola to kill billions of people indiscriminately, might be happy. Darwin will ensure that the next generation of organisms on earth will be heat-tolerant, acid-tolerant, and will vote Democrat. That’s not an absurd thought at all, now is it? Not for the scientific consensus.Dr Eric Pianka, ardent evolutionist and genocide advocate, by J B Greene. Used by permission.
13 October 2015The Council for Scientific and Industrial Research (CSIR) is celebrating its 70th birthday this year, and at its annual two day conference, held on 8 and 9 October, the focus was on the impact and breakthroughs the organisation has had over the past seven decades.Besides hosting the conference, the CSIR is also educating the public on its work and achievements via radio, print and television broadcasts.The CSIR is one of the leading science and technology research, development and implementation organisations in Africa. Constituted by an Act of Parliament in 1945 as a science council, the CSIR is committed to supporting innovation in South Africa to improve national competitiveness in the global economy.Advertising campaignPhase two of its advertising campaign started on 12 October, according to Tendani Tsedu, the group’s spokesperson. “This is the first advertising campaign for the CSIR. We wanted to show the public how the work that is being done by the CSIR affects them on a daily basis,” he explained.It falls under the Ideas that Work initiative. In one of the videos, the narrator asks the question: “What if there were people who were quietly working to make your life better, without you even knowing?”Watch one of the advertisements being shown on South African television channels till 10 December:Tsedu said the aim of the advertising was to show the impact of the CSIR’s research on society, industry and other sectors. “Another factor (for the advertising) was to increase the visibility of the CSIR and also to attract young people towards science. We want them to know that science is fun and exciting.”In just one recent innovation, in 2013 CSIR researchers developed the world’s first digital laser. It was regarded as a milestone in laser technology and could spur future laser-related innovations.The team found that laser beams could be digitally controlled from within a laser device. Their findings were published in the prestigious Nature Communications journal, on 2 August 2013.Find out how to make the CSIR your career choice:The conferenceThe CSIR’s 5th conference was attended last week by 1 500 delegates, said Tsedu. Guests included Deputy President Cyril Ramaphosa, Minister of Science and Technology Naledi Pandor, members of the science and technology portfolio committee, research partners such as Eskom, Transnet and the South African National Defence Force, and university students.Speaking on the first day, Ramaphosa said that continuous investment in research and development was critical for South Africa to achieve the goals of its National Development Plan (NDP).“The NDP says that science and technology must be used to address some of the problems in education, health and economic development, and it must facilitate access to information and knowledge,” said Ramaphosa.Watch the deputy president explain why the government will invest in solution- driven technology:Research out of the labAt the conference, CSIR scientists presented their work to the public. About 20 exhibitions covered energy, health, defence, built environment, ICT, natural environment and industry. Tendani Tsedu of CSIR said during their 5th Conference the scientists had an opportunity to present their work to the public. (Image: Supplied)“They had a chance to take the research out of the lab and discuss it in an open forum,” said Tsedu. “The robust debates and engagement with the industry, government departments, businesses and other science councils were inspiring and constructive.“Those who attended (the conference) now have a better idea of what is the CSIR and how can they use science to solve issues that they are facing,” he added.Another highlight was the launch of a commercial product with Nestle South Africa. The CSIR teamed up with the Agriculture Research Council, Nestle and University of Fort Hare to develop Maggi 2 Minute Noodles with morogo, or African spinach. This product, which is already available in supermarkets, is a good example of what can be achieved if private and public companies work together to address issues such as unemployment and poverty.Delegates tweeted about the sessions:@CSIR Dr Busisiwe Vilakazi is the last Health speaker of the #CSIRConference #CSIR70 All speakers have been excellent pic.twitter.com/RudpOUeHin— Lyndi Jonker (@lyndi_j) October 9, 2015#CSIRConference .

The vibe of Ford’s small outpost in the heart of Palo Alto is straight-up Silicon Valley start-up: empty cubes, diagrams scribbled on wall-sized whiteboards, and a lounge with multiple game stations. (I didn’t see a foosball table.) T.J. Giuli, the guy in charge, sports a ponytail and goatee – and holds a Ph.D. in computer science from nearby Stanford. His first hire, Dave Evans, also a Stanford-trained research engineer, is attired in T-shirt, shorts, flip-flops and shades flipped back on his head. They both espouse an unabashed open-source credo. None of this is surprising until you reflect that Giuli and Evans are not toiling on the next great social media site – but the next iteration of products made of glass and steel by an old-school manufacturing company founded 110 years ago.Giuli, research lab leader at Ford’s Silicon Valley Lab, wants Ford cars to become open-source crowd-enabled modular products. “We don’t judge our success on the ideas we come up with,” said Giuli. “But the ideas from people outside of Ford. If somebody comes up with an idea I never would have thought of, then it’s a success.”In fact, the core mission of Ford’s Palo Alto research lab is to enable innovators – even those with limited resources and technical chops – to see the automobile as a platform for creativity. Giuli points to a disembodied car dashboard and steering wheel, out of place in this office setting.“Let’s say you don’t like these steering wheel buttons. Maybe you could slap in a capacitive touch controller,” he said. “Using this platform, people would, by themselves, be able to design things.” The lab also maintains two vehicles in its parking lot for testing.In the next few months, Ford expects to release the beta version of its car app developer kit. There are already more than 1,000 developers waiting to be notified when it’s ready. At that point, this lab’s work will shift to supporting and growing a community of car hackers. “We’re interested in spurring the creation of an ecosystem,” Giuli said.Trading Grease For CodeFord’s OpenXC API runs on a combination of Arduino and Android platforms – technology chosen to make modding your car as easy as programming a smartphone. The system can potentially access the 1,000 or more data points, generated by sensors on Ford vehicles and served up via the 16-pin onboard diagnostics port (a standard feature of all cars since 1996). The Ford toolkit encourages development of software as well as add-on hardware.Evans, a mechanical engineer with expertise in rapid prototyping and digital manufacturing technology, comes naturally to the automotive industry. His father is Andy Evans, a profession race car driver, who drove for Ferrari in the 1990s in the World Sports Car series. “I have cars in my blood,” said Evans.“When you think back to the days of the 1960s Mustangs, you’d pop open the hood. If you knew what you’re doing, you could change all kinds of mechanical things,” said Evans. “But now, if you open up the hood of your car, what do you see? Plastic. It’s intimidating.” The answer: Ford wants to transform 20th century grease monkeys into 21st century DIY car geeks. Ford first announced its OpenXC platform a year ago at the TechCrunch Disrupt 2011 Hackathon. Since then, the Ford Silicon Valley Lab has vetted its process, sometimes working with partners, by evaluating a number of hacks:Using the rate and duration of windshield wiper activity, cars become roaming weather stations capable of reporting rain and other conditions on a microclimate level.Got an overbearing mother who insists on knowing when you arrive at a destination? With a hack, the car texts, “Oy vay, I’m here already.”Looking at steering wheel angle, accelerator pedal position, speeds, RPM, and GPS location, an app determines that you just completed a fun drive on a twisty road. It does a GPS trace and tweets the deets, including a link to a Google map.An obvious application is traffic detection, which is not such a big deal in U.S. where traffic reports are everyday radio fare, but could be huge in the developing world. If multiple drivers repeatedly slam their brakes on the same stretch of road, traffic planners could learn there’s a safety problem in the road design.From there, who knows what innovation could emerge from an online community of car hackers? Ford’s lab is not currently constrained by a need to commercialize any of the ideas but sees its work instead as research regarding the feasibility of a car-based open source strategy. Giuli will grow the lab’s staff from three employees currently, to about 10 to 15 people in the next three years.Ford might seem forward thinking in establishing such a lab, but Giuli doesn’t see it that way. He believes it’s more a matter of keeping up with where innovative geeks are already going. “Tons of people are already making car apps that work with OBD2 readers, or replacing the center stack with their own car computer. Why Tech Companies Need Simpler Terms of Servic… That’s happening today, and there’s nothing that anybody can do to stop it,” he said. “So, it’s a good idea for OEMs like Ford to make this really easy. Hopefully, we can benefit customers with a lot of awesome new features.” A Web Developer’s New Best Friend is the AI Wai… Tags:#Internet of Things#web Top Reasons to Go With Managed WordPress Hosting Related Posts bradley berman 8 Best WordPress Hosting Solutions on the Market

The organizational development class I was taking at Harvard Business School included a group project. The project was based on a scenario in which all the members of the group were in a hypothetical plane crash in what the script called “the Canadian swamplands.”The exercise required each member of the group to look at a list of resources available and put them in order based on their importance to survival. The list included things like the tires from the plane’s landing gear, pills that would purify water, matches, the fuel from the aircraft, and about 15 other items.Each member of the group was to share their ranking with their team and make one single decision: Do you stay put and wait for help, or do you attempt to cross the 50 miles of “Canadian swamplands,” and make it to the nearest town.As we ranked the items, we learned from each other. I ranked the pills that would purify water as my number one resource. One of the members of my group, however, was a doctor, and he insisted that in the Canadian area where we were stranded, the water was cleaner than almost any water found on earth. He said to throw the pills away. We all went through the exercise of discussing each item and re-ranking them based on the knowledge of the entire group. We were smarter together than we were alone. (Out of 125 or so people, no one had a worse first ranking of these items than me, and no one had a greater improvement after re-ranking them with their peers).That learning outcome by itself would’ve been enough, but we still had to answer the question as to whether or not to stay put or attempt to cross 50 miles of harsh terrain. Of the 10 or so people in the group, only one of us suggested that we cross the 50 miles together. That one person was me. I have a strong bias for action.At the time I was taking this class, I was routinely riding a bicycle 100 miles every Saturday and another 75 or more miles every Sunday, in addition to what I rode throughout the week. Fifty miles is a long way to walk, and over tough terrain, it would be even worse. I believed it could be done, and argued that the tires from the airplane and the rope we had recovered from the plane crash would allow us to cross the water safely. But my peers argued vociferously against my plan. They won the argument, but I negotiated that we would wait three days, and then we would walk together to the closest town.The Royal Canadian Mounted Police officer who showed up on a videotape to describe our situation and what the right choices were suggested that we would have likely been lost and died had we tried to cross the 50 miles. He said it was better and more likely that we would have been found had we simply waited to be rescued. Honestly, I am not very good at waiting. Riding 100+ miles dressed in lycra with only water and a few energy bars would have given me the confidence to give it a go and start walking, even though I liked the idea of catching the tires on fire to generate enough smoke to allow rescuers to locate my team.As I am reading Charles Duhigg’s new book, Smarter, Faster, Better, I am reminded that a “bias for action” and a “locus of control,” (believing that you have a choice and can complete some arduous task) is the foundation of motivation. When we win deals, we talk about what we did to win, as if it was all our volition. When we lose deals, we pretend that certain factors beyond our control caused our loss, that we were powerless. The problem with believing that forces beyond your control are what causes your losses is disempowering. It means that you have no control, that you have to sit passively while the world acts on you.The time to take the actions that ensure you win deals-or greatly improve your chances—is now. The time to deal without whatever obstacle you believe will cause you to lose is before you have lost. No one is coming to rescue you and your deal. You are going to have to save yourself.

A 30-year-old man was killed and his friend sustained head injuries after the two were allegedly pushed off the moving local train on the Delhi-Agra route near the Asaoti Railway Station here on Saturday, by a group of teenage students following a minor altercation. Three of the accused were arrested, while the fourth managed to escape.Same stationThe incident comes less than two months after Junaid, a minor Muslim boy from Khandawali village was stabbed to death, and his older brother seriously injured in a similar fashion, by a group of men, following an argument over a seat in a local train at the same railway station.The deceased in the present case has been identified as Devender Kumar, a resident of Mohan Nagar in Palwal. Lalit, 29, who was injured in the incident, belongs to Tikri Brahman village in Palwal.Superintendent of Police, Haryana Railway Police, Kamal Deep Goyal told The Hindu that the accused, all of them students, were headed to Agra for a fun trip when they entered into an altercation with the accused on the train around 8:30 p.m. “One of the accused students got down at Asaoti railway station to fetch drinking water from a tap. He had an argument with the duo travelling on the footboard of the train when he tried to board the train and asked them for the passage. Later, his friends also got embroiled into it and the four allegedly pushed the two off the moving train,” said Mr. Goyal.Three caughtThree of the accused were caught by fellow passengers and handed over to the police at the Palwal Railway Station, but the fourth managed to jump off and escape when the train slowed down. “He will also be arrested soon,” said Deputy Superintendent of Police, Faridabad Railway Police, Mohinder Singh.The three have been identified as Manmohan alias Mohit, Vipin Gupta and Maniket Jaiswal. While Maniket belongs to Faridabad, the other two belong to Delhi.Though the accused maintained that the duo fell off accidentally during the scuffle, the police have registered a case of murder and attempt to murder under the Indian Penal Code based on the statements of fellow passengers.Devender, who worked at a workshop in Ballabgarh, is survived by his wife and four children, including two girls. Lalit also works at a lathe machine in Ballabgarh and would usually travel with Devender on his way back home. He was admitted to the AIIMS Trauma Centre and discharged on Sunday evening.

Dalian Yifang attacker Carrasco in contact with Arsenalby Paul Vegas10 months agoSend to a friendShare the loveBelgium winger Yannick Carrasco has emerged as a target for Arsenal.Sky Italia says the 25-year-old left Atletico Madrid to join Chinese Super League side Dalian Yifang in February last year.Arsenal have made initial contact with the Belgian international, who has given his ‘approval’ to the move.Carrasco is said to be open to moving to the Premier League with the Gunners now favourites for his signature.Milan had been keen on Carrasco and the player even liked a social media post about a potential move to the San Siro.But there are doubts over whether Milan would be able to afford the deal, with Carrasco currently pocketing around £170,000-a-week in China.
