Dark Matter: Where Is It?

first_imgIf physicists and astronomers are going to continue to tell us that 95% of the mass in the universe is hidden in some unobservable dark matter, they had better find it soon.  Two articles on PhysOrg (#1, #2) reported on continuing efforts to find the elusive stuff – if it exists at all.  The first article begin quizzically,95%.  That is the percentage of the known Universe that is missing.  As in it is not there.  Or at least if it is there, we can’t see it.  We call this unseen stuff “dark matter”.  That has been well known for sometime.  What is trickier in answering is why?  Why is it that 95% of the universe is made up of this so-named “dark matter?”  An even trickier question is where?  As in where is this dark matter?  It is those two questions that have plagued physicists for decades.  Dark matter, by its own definition cannot be seen, hence its name.  So how do we “see” it, how do we know “where” to look?The article announced that “for the first time, a team of physicists has gathered evidence.”  What qualifies as evidence, though, may be in the eye of the beholder.  What some physicists found was high-energy positrons from space.  Any connection to dark matter (in this case, weakly-interacting massive particles, or WIMPs) is highly theory-dependent.    The second article did not claim evidence – just the desire to find it.  A Columbia physicist put it this way: “Sometimes I think of dark matter as a mysterious woman with her face covered by one of those beautiful Venetian masks.  All of us experimentalists are driven by one desire: to uncover that face.”    Researchers are spending millions of dollars looking for something that may not exist.  There are only indirect reasons for suspecting its existence: theories that require it, and galaxy clusters that would have disrupted from their own internal motions if they are as old as claimed.How is this different, functionally, from invoking miracles or occult substances to keep one’s pet belief intact?  Keep track of this dark matter story.  We’ll have to see if it becomes a 21st century analogue of alchemy.(Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Reverse Engineer Living Solutions

first_img(Visited 38 times, 1 visits today)FacebookTwitterPinterestSave分享0 Need solutions to practical engineering problems?  Save time and effort; see how animals and plants do it.Bee in the wind tunnel:  Harvard researches are wondering how bees fly stable in the wind and rain.  Miniature flying robots have trouble even in slight breezes.  By watching bees in a wind tunnel in slow-motion, researchers hope to use what they learn to design “bad weather robots,” the BBC News reported.Bug treasures:  Seeing how “bug biology” is leading to better materials and reducing pollution, Science Daily reminded its readers, “those creepy crawlers we try so hard to avoid may offer substantial solutions to some of life’s problems.”  How does an artificial ligament sound?  Or a chemical-free way to protect crops from pests?  Want bigger biceps?  Then support your local biomimetics researcher.  “Although few gym rats want to admit it, whispery moth wings and bulging human biceps aren’t that different. What we learn from them can teach us more about human muscle mechanics to potentially improve physical therapy treatments and further understand diseases attacking the muscular system.”Bacterial implants:  What a concept: implants made from biomolecules that are absorbed by the body after they do their work.  No more screws, pins, or plates, according to Science Daily; the implants are made biologically by bacteria.  Not only that, the “The production is completely independent of fossil resources, so there are no negative affects on the body.”Bug-eye lens:  A lens combining technologies from human eyes and insect eyes has been developed at Ohio State, Science Daily reported.  It works great for those super wide-angle views.  “The results could be smartphones that rival the photo quality of digital cameras, and surgical imaging that enables doctors to see inside the human body like never before.”  They get the best of both: “combines the focusing ability of a human eye with the wide-angle view of an insect eye to capture images with depth.”Rose tape:  Our standard adhesive tape works fine, until it gets wet.  Wouldn’t it be nice to have adhesives that stick in spite of wetness?  Take time to smell the roses, and to study them, too, like researchers at the University of Sydney, who are intrigued with how water beads up on rose petals.  The secret is in the nanostructure, Science Daily reported, and it ain’t simple: “The reasons for this are complex and largely due to the special structure of the rose petal’s surface.”  Once they figure it out, numerous applications are in view, like self-cleaning glass.Plant cures:  Pharmaceutical companies spend so much money and time developing drugs from scratch.  Maybe they should spend that effort learning to read “nature’s library,” another article on Science Daily says.  It might lead to cures for AIDS, cancer, and Alzheimer’s Disease.  The approach being advocated by the American Chemical Society takes heart at the discovery of a treatment for viral hepatitis found in a tree that grows in Samoa, the mamala tree.  It’s a non-evolutionary lesson for all on the design value of biomimetics:The mamala tree did not start making prostratin millions of years ago to treat a disease that appeared in the 20th century. The same is true for other substances that occur naturally in plants and animals. But we now have the tools to read nature’s library and use the lessons learned there to design, make and study new molecules that address unmet medical needs. This “function-oriented” approach seeks to identify useful parts of molecules and then, based on this knowledge, to design new and more readily synthesized molecules that work better or work in totally new ways. This is a well-validated strategy, perhaps best exemplified by the emergence of modern aviation from knowledge of how birds fly.”Reverse biomimetics:  Here’s a case of humans inventing a molecule to treat pain, only to find it in the roots of an African tree.  Nature told how “An African plant used in traditional medicine for pain relief contains the same active ingredient as an artificial pain killer” called tramadol that was found inside the roots of the pincushion tree.  “The researchers believe that this is the first time a widely prescribed synthetic drug has been found in a plant at clinically relevant concentrations.”  Nature had it first (see also “More Reasons to Love Plants,” 9/10/13).Capture the light:  Photosynthesis continues to be a mainstay in biomimetics research.  If we could only capture sunlight as efficiently as plants do, it would revolutionize our energy industries.  Science Daily tells how a scientist at Okayama University in Japan has already spent 20 years of his life trying to figure out how plants do it, in order to develop “methods for producing an unlimited source of clean energy.”  He’s getting warmer but not there yet.In the journals, too:  It’s not just the popular science outlets promoting the biomimetics parade.  Leading science journals are in it, too.  Science talked about lighter, stiffer materials that mimic cellular structures and honeycomb.  Nature showed how the recent discovery of gears in an insect (see 9/16/13) is an example of reverse biomimetics.  And PNAS discussed a new “microbial battery” that harnesses the “oxidative power” of microorganisms to get power out of sewage and other gunk.We’re so glad that biomimetics has been a force for good for nearly a decade now.  There were earlier examples (like Velcro) but the imitation of nature really took off after the turn of the millennium.  Now there are whole university institutions devoted to it, and journals.  This is good science for everyone.  It takes the focus off of useless Darwinian tales and puts it on intelligent design.  It also provides fodder for entrepreneurs, helps the economy, and can even save lives.  By providing insight into the wonderful workings of nature with a potential for practical applications, it’s making science fun again.last_img read more

IoT gives field service something it’s never had: visibility

first_imgTags:#IIoT#Internet of Things#IoT#PTC#Servicemax When you think about field service, what comes to mind? If it’s not literally delivering service in the field, then you’re probably seeing hard hats, safety glasses and leather tool belts surrounded by industrial machines.You’d be mostly right, because for a long time that’s how it’s looked. Lots of manual processes, reacting to broken equipment and toting the traditional hardware of years past.But thanks to the advent of widely available data-rich Internet of Things (IoT) sensors, cloud and mobility, the face of field service is completely changing. It’s now less about fixing malfunctioning stuff and more about implementing service plans that ensure stuff never malfunctions in the first place. And people are willing to pay for that assurance.See also: Making the megacity sustainable with IoTWhile IoT frequently gets associated with novel consumer applications, it’s found a highly productive home with field service once integrated into the broader field service management platform. In fact, McKinsey predicts that 70% of IoT application will take place in industries across the B2B-heavy enterprise like field service. Like IT, CRM, HR and marketing have all seen over the past decade or so, field service is now finally getting its due tech makeover and showing incredible business benefits along the way.As the CEO of our partner PTC, Jim Heppelmann, once said, “Service is the first killer app for the Internet of Things.” In a survey we just conducted, nearly every single respondent said they see the benefit of field service management – and 90 percent cite benefits from connected equipment specifically.Where we once flew blind….But beyond the obvious benefits of connectivity like proactive service ahead of a system breakdown, or building a repository of real-time machine status updates, the host of disruptive technologies are finding applications within field service for one reason above all else.It provides full visibility where, previously, there was little to none at all.Say for example you’re deploying a service technician to repair a wind turbine that’s acting up. Traditionally, that technician is going to have to scale hundreds of feet up in the air, take diagnostics, climb back down, order the part, return in the next few days, climb back up, fix it and get back down. And that doesn’t include time spent on the invoicing and other paperwork.What a slog.But the disruptive technology we’re seeing gain adoption in field service is giving technicians a platform fully-stocked with automatically gathered information about equipment status, which parts to order, and information on the customer and their warranties. All of a sudden there’s a ton of visibility into what’s what before a tech even goes onsite. That’s huge. It leads to skyrocketing fix rates, new business models where a company isn’t selling products but rather outcomes – i.e, guaranteed uptime on a leased machine versus owning the actual product.All because the information comes to light through connectivity.And there’s massive potential here, especially as our own data suggests companies are going to continue adopting new disruptive technologies. Half of those we surveyed said their companies plan to incorporate connected devices over the next two years; another half added wearable technology to the mix; 51 percent plan to use augmented reality.But, as they say, with great power comes great responsibility. This kind of visibility is not only changing the business of field service, but also the nature of the skillsets – and expectations – of the field technicians themselves. Increased technician mobility, mobile and web access to a centralized operational platform and connectivity to asset data will play a crucial role in closing skill gaps and expanding the industry.Field service: where IoT squeezes out new revenue?While the IoT, augmented and virtual reality, drones, wearable technology and mobility change the way organizations operate, it is field service that’s delivering the revenue-generating benefits realized from these technologies to customers.When you arm technicians with data about customers accessible before they show up for the service call, it boosts efficiency across entire organizations. Our survey data showed the intent to deploy new technology, which points to more investment and energy spent on transforming field service organizations. In fact, 86 percent of surveyed companies see field service as becoming their primary revenue driver over the next two years.Ultimately, field service offers an IoT and connectivity proving ground for the broader enterprise and across industries from heavy manufacturing to healthcare to energy to transportation. Integrating forward-thinking technology like the IoT, augmented reality and wearables into everyday work life has the potential to shift entire business models of field service organizations.As more technicians and machines get connected, one thing is clear: linking technicians with the right information to get a job done in an efficient and quality way is more important than ever to realizing outcomes that grow business.The author is the co-founder & chief strategy officer of ServiceMax, a leading field service management platform based in Pleasanton, CA. 5 Industries Destined for Technological Disruption Related Posts The Ultimate Checklist on Ways to Prevent IoT D…center_img Electronic Design is Utilizing AI-Enabled Solu… How IoT Will Transform Cold Chain Logistics For… Athani Krishnaprasadlast_img read more
