Some would-be contenders — like Wisconsin and USC — have largely played themselves out of the playoff with quick losses. Others — such as LSU and Notre Dame — have bolstered their resumes with early wins. But there’s still plenty of football left to be played, plenty of time to see whether we’ll end up with more of the same or something new by season’s end.To help make sense of it all, FiveThirtyEight is relaunching its College Football Playoff prediction model this week. You can read about how it works in detail here, but the basic premise is that we simulate both the results of future games (using a mix of ESPN’s Football Power Index and the committee rankings) and the behavior of the playoff committee to arrive at each team’s chances of making college football’s version of the Final Four. And according to our model, four very familiar teams — Alabama, Ohio State, Georgia and Clemson — are the early leaders in the national title race, with Oklahoma and Notre Dame lurking not too far behind. 4ClemsonACC5-0191811Boston College4711 21FloridaSEC4-117489Georgia31 Surveying the 2018 College Football Playoff raceChance of making the College Football Playoff and winning the national championship for teams with at least a 1 percent title probability 20Oklahoma St.Big 124-1170511Oklahoma51 16AuburnSEC4-1182713Alabama31 Danger week*Chance to… For five of those teams, the path ahead is relatively straightforward: Win, and you’re probably in. Our model says Alabama, Georgia, Ohio State, Clemson and Oklahoma (sorry, Notre Dame) all have a greater than 99 percent chance of making the playoff if they win their remaining games. That will be easier for some than others — the Tide and Buckeyes have about a 1-in-3 chance, the Tigers’ odds are more like 1 in 4,1If not lower, given their ongoing QB drama. and the Bulldogs2Who would theoretically face Alabama in an SEC title-game matchup. and Sooners are around 1 in 10 — but each does at least control its own destiny.The same goes for three other squads, who also have a greater than 99 percent chance of making the playoff if they win out: West Virginia, LSU and Kentucky. But before fans in Morgantown, Baton Rouge and Lexington get too excited, the odds of them doing that are pretty low. FPI is skeptical that the Wildcats are very good; LSU still has to face Florida, Georgia and Alabama over a brutal monthlong stretch starting this weekend; and the remaining Mountaineer slate is no walk in the park either. It’s possible that at least one will finish with a single loss or fewer (the traditional playoff recipe for major-conference schools), but the path will be difficult.Among the teams that need a little help, Notre Dame easily has the best playoff outlook. The Fighting Irish’s most difficult remaining opponent might come this very week — a Virginia Tech team that also lost to Old Dominion two weeks ago — so red-hot QB Ian Book could be in a good position to lead Notre Dame to its first playoff berth. The Irish may not quite be playoff locks if they win out; our model says they’re at 87 percent if they run the table, meaning they’d also need one of the big-name teams to slip up along the way.3According to our model, the four teams whose playoff candidacies are least compatible with Notre Dame’s are Clemson, Ohio State, Oklahoma and Washington. But the last time a Notre Dame team unexpectedly rattled off an undefeated regular season, it went to the Bowl Championship Series title game, and it’s hard to believe it wouldn’t get the same treatment from the committee this season.Poor Central Florida probably won’t get the same benefit of the doubt, though. Despite opening the season 4-0 to extend the program’s winning streak to 17 consecutive games, the Knights have just a 2 percent chance to make the playoff in our model — and they’re only an 11 percent shot even if they manage to go undefeated for a second straight season. Between bad luck (a potentially resume-boosting Power Five road game against North Carolina was canceled because of Hurricane Florence) and the committee’s apparent unwillingness to even consider undefeated non-power conference teams over major-conference schools with multiple losses, UCF could very well find itself settling for a self-declared national title yet again by season’s end.The rest of the potential contenders have losses on their resumes, and that means serious question marks for their playoff chances. Washington’s opening-week loss to Auburn, for instance, instantly put the Huskies behind the eight ball, though they still have time to play their way back into the playoff picture if they keep winning (and, say, Notre Dame loses). Penn State still has a 10 percent shot at the playoff, despite last Saturday’s crushing late-game defeat against Ohio State, but they — along with fellow Big Ten hopefuls Michigan and Wisconsin — have plenty of work cut out for them. At least the Wolverines and (maybe) the Badgers4If they make the Big Ten title game and are matched against Ohio State. still have their chances to knock off the Buckeyes. In that regard, Penn State already blew its shot at a big, playoff-worthy statement win. Miami, meanwhile, may have short-circuited its chances early on with a 33-17 loss to LSU in the first week; the Hurricanes’ playoff hopes now rest on running the table and potentially beating Clemson in an ACC title-game rematch. Although these teams can still make the playoff, their margins for error are razor-thin.But let’s be honest: The playoff chase still mainly revolves around the preseason favorites. There’s a 65 percent chance that the national champion is one of Alabama, Ohio State, Clemson and Georgia, which leaves just 35 percent for everybody else in the entire country. Although not even this year’s ridiculously dominant Crimson Tide team is necessarily guaranteed to make its fifth straight College Football Playoff appearance, it would be a surprise if Bama and its top rivals didn’t find their way into the playoff by season’s end. In today’s college football reality more than ever, the powerhouse programs are seated at the dinner table, and everyone else is left to fight over the scraps.

Washington is in danger of similar collapse, narrowly falling the last two weeks in winnable games against the Cowboys and Cardinals. They’d be out of the playoffs if the season ended today, and this week Philadelphia has the opportunity to play spoiler and knock another 18 percentage points or so off their rival’s chances. 3.

While the 11-1 Cowboys don’t quite have a lock on the NFC East title, they will at least make it as a wild card. They’ll now be playing for a bye and home-field advantage while the rest of the league fights for the remaining playoff spots.For the last couple weeks, we’ve been using the model behind our 2016 NFL predictions to calculate how much each team’s playoff chances “swing” depending on the outcome of each game. For example, we currently give the Pittsburgh Steelers a 67 percent chance of making the playoffs. If they beat Buffalo this week, we project those chances will increase to 84 percent (independent of other games). If they lose, their chances drop to 53 percent.1Our NFL predictions are based on 100,000 simulations of the rest of the season and are updated after every game ends. In the simulations in which Pittsburgh beats Buffalo, they make the playoffs 84 percent of the time. In simulations where they lose, they make the playoffs 53 percent of the time. But it’s unlikely that Pittsburgh’s playoff probabilities will be exactly 84 percent or exactly 53 percent at the end of Week 14, because the team’s chances depend on the outcome of several games (most notably Baltimore’s), not just their own. That’s a 31 percentage point swing! By doing this same math for every matchup and factoring in how each team’s resulting record will affect others’ playoff odds, we can find out which games are the most impactful.Here are the top five for Week 14: CHANCE OF MAKING PLAYOFFS AFFECTED TEAMCURRENTIF NO WINSIF TB WINSSWING Baltimore39%66%32%35– Denver70%82%43%39– Indianapolis3945955– Minnesota2833258– 2.

Tennessee has had a commendable bounceback season, but they’re in a tough playoff situation. The AFC West’s success means that even if the Titans run the table to end the season at 10-6, that might not be enough to make it as a wild card, and their 0-3 record against the Texans and Colts makes it unlikely that they’d win a division tiebreaker. We give them just an 11 percent chance of making the playoffs, much lower than the chances of Green Bay, Minnesota, Indianapolis and Houston, who all share the same 6-6 record.

A Rebuttal to an Additive-Manufacturing SkepticBy Chris Wood, Senior AnalystWhile surfing the Technology Review magazine website last week, I came across an article written by Christopher Mims titled Why 3-D Printing Will Go the Way of Virtual Reality. The gist of the article is that 3D printing is cool, but it’s not the revolution in manufacturing that many (we included) have claimed it to be. [Ed. note: In case you missed it previously, our introductory article on 3D printing from several months ago titled A Manufacturing Revolution is a good overview of the technology.]According to Mims:3D printing, like VR [virtual reality] before it, is one of those technologies that suggest a trend of long and steep adoption driven by rapid advances on the systems we have now. … But the notion that 3D printing will on any reasonable time scale become a “mature” technology that can reproduce all the goods on which we rely is to engage in a complete denial of the complexities of modern manufacturing, and, more to the point, the challenges of working with matter.While Mims’ article makes some valid points, his analogy comparing 3D printing to virtual reality [epitomized by the movie Lawnmower Man] is misplaced; and he seems unclear on what it is that 3D-printing bulls actually expect from the technology. What’s more, he fails to mention recent advancements that have vastly expanded the markets 3D printing can serve.As we’ve noted before, 3D printing is already a $1 billion+ business according to the most recent Wohlers Report. 3D-printing companies like 3D Systems (NYSE.DDD) and Stratasys (NASDAQ.SSYS) are both pulling in north of $140 million a year in revenue, and growing fast. I don’t recall any virtual reality companies generating anywhere near that level of sales. VictorMaxx Technologies – maker of the CyberMaxx Virtual Reality Headset – discontinued operations only 18 months after going public at the end of 1996, with revenues of $750,000 and a net loss of $3 million.Furthermore, advocates of 3D printing are not suggesting that these technologies will ever “reproduce all the goods on which we rely.” We are saying that this thing is going to be huge; it already is.For those not familiar with the subject, 3D printers take a three-dimensional CAD (computer-aided design) and create a physical product from the specs layer by layer, usually by extruding thermoplastic modeling material or sintering metal powders or liquid photopolymers via lasers or electron beams.This technology will not go the way of virtual reality for many reasons, including:The numerous benefits 3D printing has over traditional manufacturing processes;The breadth of market penetration the tech has already accomplished with current applications;The technological advancements that have expanded its market opportunity; andThe increased ease of use and burgeoning consumer market.Benefits of 3D PrintingThe various technologies involved in 3D printing are already changing the world through their myriad benefits over traditional manufacturing processes.Some of these benefits include:Rapid Deployment – Time to market is reduced. Since 3D printing eliminates the need for tooling, manufacturing can begin immediately after a component’s design is complete. What used to take days, weeks, or months can now be measured in minutes and hours.Low Capital Expenditure – Eliminating tooling also reduces the cost of manufacturing. Traditional dies and tools are expensive. By cutting out those expenses, 3D printing allows for a much lower initial cash outlay to ramp up manufacturing.Less Waste – While traditional “subtractive” manufacturing processes can often remove up to 90% of the raw material to arrive at a finished component, 3D printers only use the material they need to make the part.Freedom of Design – Traditional manufacturing methods are bound by rules – such as design for manufacturability (DFM) and design for assembly (DFA) – that govern the complexity and ultimately the performance of products. Since 3D printing constructs parts with an additive fabrication process, complex designs are just as fast to manufacture as simple ones. In fact, 3D printers can actually create structures that are more intricate than any other manufacturing technique and that are impossible to build any other way. You can create parts with moving components, hinges, and parts within parts. Changes cost almost nothing to make. Thus, 3D printing promotes product innovation and allows design to be highly optimized for performance.Current ApplicationsAerospace to academia and everything in between can have an application in 3D printing. It doesn’t make sense to say 3D printing will never become a “mature” technology, considering the breadth of industries it has already penetrated. 3D printing technology is used frequently in the fields of aerospace, architecture, automotive, dental and medical, education, engineering and construction, footwear, jewelry, industrial design, and the list goes on. And while rapid modeling and prototyping still makes the biggest business case for 3D printing, the machines are increasingly being used to make final products too. According to Wohlers Associates, more than 20% of the output of 3D printers is now final products rather than prototypes. The firm predicts that this figure will rise to 50% by 2020.In the meantime, in addition to the more traditional applications – like motorcycle maker Ducati, which was able to cut 20 months and more than 70% from the development time of a new racing engine thanks to prototyping with a 3D printer – we have MIT 3D printing solar cells on paper, designer Enrico Dini 3D printing whole buildings, and scientists 3D printing human veins… not to mention the first 3D-printed car that recently rolled off the press.AdvancementsWhen 3D printers first hit the scene in the early 1980s, they were rather crude by today’s standards. Recent advancements in what they can do and the materials they can do it with have guaranteed the technology’s use in a growing number of markets in the years to come.Today, we have 3D printers that can build structures nearly three meters high. On the other end of the spectrum there are machines that can 3D print microstructures with intricate designs as small as just a few micrometers in diameter. Using a technique called two-photon polymerization (2PP), Klaus Stadlmann was able to 3D print an object at 20 micrometers – approximately the size of a dust particle.Improvements in the 3D printing processes themselves are important. But it’s the new materials available that have made it possible to produce low volumes of high quality, complex models, parts, and complete end-use products. These are products that meet the rigorous requirements of the industries they serve – from skateboards and shoes all the way to spinal implants created out of medical-grade titanium, and engine parts.Private company Objet, for example, offers 3D printing solutions with a choice of over 60 materials capable of simulating properties including varying grades of rubber, clear transparency, and rigid, ABS-grade engineering plastics.Here’s a picture of a stool the company created in a single print job that is capable of supporting more than 220 pounds:Meanwhile, a company called Shapeways offers 3D-printed objects in materials such as acrylic plastic, stainless steel, sterling silver, ceramics, glass, and full color sandstone – all with a variety of finishes available.EOS is able to 3D print top-quality metal parts like a patient-specific knee implant (left) using a biocompatible cobalt-chrome alloy, and a fuel-injection nozzle (right) for gas turbine applications using cobalt chrome.3D Systems has printers that use commercially available, gas-atomized metallic powders to produce fully dense metal parts in materials including titanium, stainless steel, cobalt chrome, and tool steel.Ease of UseIn addition to becoming more advanced, 3D printers are also becoming smaller, cheaper, and much easier to use, which should help the consumer market grow beyond just the most hardcore hobbyists.Early 3D printers were highly complex, rather large, and very expensive, targeting only the largest manufacturers that could afford their several-hundred-thousand-dollar price tags. That’s not the case anymore. While very high-end printers can still cost as much as $1 million, the options available to consumers are growing by leaps and bounds.At the recent Consumer Electronics Show in Las Vegas, we were introduced to two new 3D printers that should help bring 3D printing to the masses.3D Systems introduced its $1,299 Cube 3D printer. The name of the game with this machine and the supporting Cubify website is (according to the company), “coloring book simplicity.” The Cube requires no assembly and is ready to print out of the box. All you have to do once you get one is visit the website, download the digital file of your choice, and start printing.MakerBot Industries also debuted a personal 3D printer at CES. Called the Replicator, this machine is capable of printing in two colors, but it costs several hundred dollars more than the Cube and requires some assembly after purchase. MakerBot’s printer, however, is all open source; and the company has a site called Thingiverse, where it shares all the digital file designs (and the designs for the printer itself) for free. So you can just download whatever you like, and you can modify it and make it yours if you like.And if you’re the type who likes to create your own designs rather than just downloading the work of others, there’s free software like Google SketchUp, which allows you to create products from scratch relatively easily.Will this increased ease of use ever lead us to the utopian future where we can all instantly download and manufacture anything, anytime, anywhere? Who knows? But we do know that as the technology progresses and costs go down, 3D printers will become more attractive to consumers.ChallengesWe’re not suggesting that 3D printing will soon – or ever – replace all traditional manufacturing processes. There are many challenges that still lie ahead. Despite all the benefits of the technology, several factors capable of curbing its adoption and hindering its growth must be acknowledged.For starters, 3D printing is not presently a high-volume manufacturing process. 3D printers would be advantageous for production quantities ranging from one to at most several thousand units per year, and where quick modification and customization capability is desirable. But if the demand is for millions of identical units a year, 3D printing is not yet the right solution.What’s more, you’re probably giving up some output quality when you choose 3D printing over traditional manufacturing. Despite ongoing technological improvements in this area, 3D printing cannot yet fully compete with injection molding. 3D printers are capable of holding accuracies that are approximately +/- 0.005-inch for small to mid-sized parts, whereas injection molding is capable of holding +/- 0.001 to 0.002-inch tolerances across all features of a part.Lastly, despite the expanding number of materials that can be utilized by 3D printing technologies, the options are still much more limited than for a process like injection molding.But none of these factors is capable of sending 3D printing the way of virtual reality, in our view.ConclusionThe point is, 3D printing is simply too useful across a wide spectrum of applications to be compared to VR. It is here to stay. Going forward, the technology will displace conventional manufacturing techniques in some instances and complement them in others. Consumers will increasingly adopt it. The technology will continually be refined, while the range of usable materials will broaden. These advancements should allow us to start printing electronics in a few years… and perhaps even body parts someday down the road.This is an industry barely into its infancy. It’s a situation not unlike that with the personal computer thirty years ago, when only Steve Jobs, Bill Gates, and a few other visionaries foresaw that the PC could become an essential household appliance.Will it be the same for the 3D printer? Don’t bet against it.[Make sure your portfolio is optimally wired for profits, by choosing the right tech companies in which to invest. Get started today.]Facebook Finally Files Paperwork to Go PublicAs was expected, Facebook filed a Form S-1 yesterday, announcing its intention to offer shares of Class A common stock to the public under the symbol “FB.” The filing indicates that Facebook is seeking to raise $5 billion when it IPOs in the spring, but that number will likely increase. Also contained in the document were the detailed financial results that we’ve all been guessing at these past few years. What the numbers show us is that Facebook is a very profitable, rapidly growing business (well, duh!?!) but it might not be growing as fast as some people thought.Revenue in 2011 rang in at $3.71 billion, up 88% from the $1.97 billion the year before. Impressive. But the annual growth rate did slow from the 154% experienced in 2010. When you’re dealing with such large revenue figures you expect growth rates to decline over time (unless you’re Apple over the past several years), but you might not expect such a big reduction from a relatively young enterprise. Meanwhile, net income of $1 billion in 2011 reflects a 65% increase from the year before, but the net margin of 26.9% was down 375 basis points from 2010.With strong, growing revenues, significant profits, and 845 million monthly active users, it’s no secret that Facebook is a force to be reckoned with. When the company does go public at maybe a $75 billion valuation, it will make a lot of people very rich. Good for them; we’re happy to see the market reward individuals both for their innovations and for helping fund such endeavors.What we’re not sure of is how much love the market will give to FB in the days and weeks after the IPO, particularly after the lockup period is over. If Facebook is able to grow revenue at its current rate of 88% for, say, the next three years and can maintain its net margin of 27% (which would result in earnings of about $3.5 billion and a P/E ratio of 21 – not too much above Google’s earnings multiple of 17), then a $75 billion valuation does not look too rich. But if there’s any hiccup in revenue growth, watch out.Bits & BytesGraphene Competitor Used to Make Circuits (Technology Review)Graphene – the one-atom-thick, honeycomb-lattice allotrope of carbon – is a material with virtually limitless potential (which helps explain why its discoverers received the 2010 Nobel Prize in physics). It’s the best conductor of electricity at room temperature that we know of, and it’s also the strongest material ever tested. Because of its unique properties, scientists have believed for years that graphene might be capable of solving silicon’s shortcomings in electronics. Prototype transistors composed of graphene operate at much higher speeds than silicon ones. But a material called molybdenite has a crucial advantage over graphene that might make it the answer for smaller and faster electronics.UPenn Unleashes Swarm of Nano Quadrotors (gizmag)Scientists at the University of Pennsylvania’s General Robotics, Automation, Sensing and Perception (GRASP) Lab demonstrate in a video scene how science fiction is edging closer to reality as programmed teams of up to twenty agile-flight-capable quadrotors fly in various complex formations. This stuff is cool, but kind of creepy also. We’re probably not much more than a decade from seeing these things flying around Times Square sniffing for explosives.
