Tiger Woods Bursts Into Lead at Torrey Pines With

Rocco Mediate said Tiger Woods cannot hit the shots he used to when he was at the peak of his game. Tiger Woods went out Friday in the second round at Torrey Pines and hit shots like he used to hit when he was at the top of his game. And so, he leads the Farmers Insurance Open at 11-under after crafting a beautiful 65 that included an eagle on No. 18.Now comes the hard part.With a lead going into the weekend, Woods was all but money during the height of his dominance. He had won 30 of 32 times that he held a 36-hole lead. But of the last six times he has held that advantage, he has won just twice. Not good, especially for him.“We have a long way to go,” Woods said. “It’s a pretty tough course.”Woods shot a first-round 4-under 68 on the harder South Course in Round 1. On the easier North Course, Woods was awesome, despite a steady rain. He leads over Graham DeLaet, Josh Teater and Ross Fisher, all who sit at eight under.The timing of Woods’ play was almost on purpose to counter Mediate.“Nothing he did ever surprised me,” Mediate said to USA TODAY. “He’s that good. But he can’t do it anymore because his golf swing is different. It doesn’t produce the shots he used to hit,” Mediate added. “Do I think he’s finished winning majors? No. Does he have as much desire? Yes. But you could ask him to hit any shot blindfolded back in the day and he could. Now he can’t. I know what I’m seeing. I know what I saw before. And it’s not the same.”Maybe not, but he sure looked like the old Woods Friday.He birdied the first two holes then closed out the front 9 by sandwiching birdies around a bogey on No. 8. He parred the first four holes on the back and then made birdie on the par 5 No. 14 and the 174-yard par 3 at No. 17. Finally, he closed the round by getting on the 516-yard par 5 closing hole and making the eagle putt to send him into the weekend looking as strong as he has in some time. read more

New carbon nanotube struructure aerographite is lightest material champ

first_img(Phys.org) — Despite having a reputation for valuing intellectual prowess over physical abilities, scientists are nonetheless just as competitive as anyone else. Evidence of it exists in various fields of science as suggested by the assorted prizes that are awarded for those who achieve firsts in their particular realm of research. Also always popular are virtual contests to see who can create the smallest thing, or the largest, on in the case of aerographite, the lightest. This latest champion has been produced by a team of researchers at the University of Kiel in Germany. It’s based on carbon nanotubes and is being heralded as the lightest solid ever created. Overview of different Aerographite morphologies by controlled derivations of synthesis. Image from Adv. Mater., 24: 3486-3490. Citation: New carbon nanotube struructure aerographite is lightest material champ (2012, July 13) retrieved 18 August 2019 from https://phys.org/news/2012-07-carbon-nanotube-struructure-aerographite-lightest.html Previous champions, aerogel, and then metallic microlattice were praised in their day for not just being the lightest stuff around, but for being strong for its size as well. Aerographite beats them both in both categories. Not only is it less dense (0.2 milligrams per cubic centimeter compared to 0.9) but it’s stronger too, able to support over 40,000 times its own weight. And since it’s actually mostly air (99.99%) it can be crumpled down to almost nothing if need be because it will spring back to its originally shape without prodding. Because the new champion is four times lighter than the previous champ, researchers will be busy looking for applications for it. The current hope is that because it’s a good conductor of electricity, it can be used as an electrode in new kinds of batteries or perhaps in supercapacitors.The researchers created the new material by implementing a new kind of single-step CVD synthesis process based on freely adjustable networks using zinc oxide as a template, which in essence means, they found a new way to make the graphite grow in ways that develop into very thin strand hollow carbon nanotube structures that hold together to form a new kind of material.Interestingly, the team says that if enough of the material were made to allow it to be seen by the naked eye, which they say they can do, it would appear as a black clump of sponge-like material. They also note that they didn’t start out trying to invent a new material but found it came naturally as part of their research into three-dimensionally cross-linked carbon structures.

Mater., 24: 3486–3490. doi: 10.1002/adma.201200491AbstractAn ultra lightweight carbon microtube material called Aerographite is synthesized by a novel single-step chemical vapor deposition synthesis based on ZnO networks, which is presently the lightest known material with a density smaller than μg/cm3. Despite its low density, the hierarchical design leads to remarkable mechanical, electrical, and optical properties. The first experiments with Aerographite electrodes confirm its applicability.

8 Industries Being Disrupted by Virtual Reality

first_img Growing a business sometimes requires thinking outside the box. Opinions expressed by Entrepreneur contributors are their own. July 21, 2017 For the past several years we’ve been told that the age of virtual reality is upon us. Tech companies have introduced new hardware and updated systems to much fanfare, but so far have not been able to turn widespread interest into practice.Virtual reality, and now augmented reality, are often seen as novelties: cool to play with in a store or at that one tech-obsessed friend’s house, but most of us are not putting on clunky headsets or Google’s cardboard system and walking out the door.However, it’s finally looking like the VR and AR industries are on the cusp of going mainstream, as industries start to figure out how to implement transformative technology in the user experience. These 10 industries are pioneering ways to integrate VR and AR tech and offer customers more opportunities to explore products and services.1. Real EstateLooking for a new home or apartment can feel like taking on a second job. Between endlessly checking listing updates to taking time to visit every open house on the market, buying (or renting) a new place can be a daunting and tiresome task.But what if you could experience all that a house has to offer without leaving your home? Real estate companies are toying with VR solutions that offer prospective buyers the chance to walk through a property and survey every room, hallway, nook and cranny without actually leaving their own homes.Related: Real Estate, Movies, Retail: VR Is Exploding. The Opportunities for Entrepreneurs Are Huge.2. ZoosGoing to zoos gives people the opportunity to experience wildlife up close, albeit behind a sturdy partition. However, zoo trips often spark more questions than they answer. Most zoo experiences consist of visitors wandering from exhibit to exhibit and reading about the species on small placards and in outdated pamphlets.Guru is an app that is seeking to redefine the zoo experience by bringing the animals and their habitats to (virtual) life. The app allows users to choose customized audio experiences that share facts about specific animals, as well as behind-the-scenes videos and augmented-reality portals into the actual habitats and lifestyles of animals in the wild.Related: 12 Amazing Uses of Virtual Reality3. FashionEvery millennial woman remembers the first time she saw Cher Horowitz’s closet in Clueless — it was a magical moment. The idea of being able to test clothes and match outfits without actually having to try them on resonated with an entire generation.Now, over 20 years since Clueless sparked an obsession, Cher’s closet, or at least the idea behind it, has become reality. Gap recently unveiled a VR solution that enables customers to digitally “try on” pieces within its collection. Other retailers are bringing VR headsets into stores to allow visitors to feel as though they’re sitting in the front row at the designer’s latest fashion-week presentation.Related: Virtual Reality Is About to Change Your Business4. HospitalityThe internet has made the world a smaller place. Thanks to programs like Google Earth, people can walk pathways in Santorini one minute and find themselves at a busy Sydney intersection the next. More travel organizations are tapping into consumers’ love for virtual exploration.Expedia recently announced a new VR-based initiative that will allow travelers to “step inside” hotel-room listings before making their destination decisions.Related: Why This Restaurant Chain Has Started Using VR to Train Employees5. MedicineThe world of medicine is exploring several avenues and uses for VR to help doctors and patients. Some doctors are now wearing VR headsets in the operating room to give medical students a more in-depth look at the surgical procedures.Additionally, hospitals are experimenting with VR as a means of making patients feel more comfortable. For example, VisitU, an emerging Dutch company, has created virtual glasses to give children at hospitals the chance to experience life at home or in the classroom, even though they are bedridden.Related: VRcade: Be the First to Open One in Your Town6. Entertainment and FilmSince Hollywood’s inception, film studios and production companies have been searching for new ways to make their projects more engaging and lifelike. Now, with virtual technology, film studios have the opportunity to transform the viewing experience from passive to participatory.Companies like Within are gaining the attention and support of major studios because their technology creates fully immersive viewer experiences that, until recently, Hollywood could only dream of.Related: Google: 180-Degree Video Is the Future of VR7. FitnessMany people have a hard time self-motivating when it comes to fitness. It can also be difficult to carve out the time to travel to a gym or fitness studio to take a class. Thanks to emerging VR programs, those wanting to get in shape no longer have to sacrifice their time.Startups like Icaros are creating fitness solutions that take the boredom out of getting fit. These systems allow users to feel as though they’re actually climbing a rock wall or boxing an opponent, when in fact they haven’t left their living rooms.8. AutomotiveHistorically, the automotive industry has needed a physical shopping experience to stay afloat. Before people are willing to make huge investments in new vehicles, they usually want to test the car out for themselves. For this reason, the automotive industry has struggled to find ways to connect with younger generations. Not only are millennials and Gen Zers supporters of the ride-sharing economy; they’re also digitally driven shoppers. Now, automobile makers like Ford are introducing VR experiences intended to give shoppers a real sense of a car’s interior and create a strong enough virtual experience to encourage them to visit a dealership and test drive the real thing.
