News in Brief: Particle caught flip-flopping A particle with an identity crisis could provide the next big discovery at the world's largest particle accelerator. The D meson has been caught in the act of flipping between matter and antimatter, researchers report online March 5 in Physical Review Letters. D mesons, like other mesons, are short-lived particles that emerge from the shrapnel of proton collisions at CERN’s Large Hadron Collider outside Geneva. All of these particles decay within tiny fractions of a second. But four mesons, including the D, occasionally do something strange first: They become antiparticles.

Accelerators The Large Hadron Collider is latest member of CERN's collection of extraordinary high-energy facilities and is the world's largest and highest-energy accelerator. It occupies a 27 kilometer circumference circular tunnel near Geneva which overlaps the Swiss-French border, the same tunnel that contains the LEP. Successful particle beams were produced in the LHC in 2008 and in 2010 the two beams reached 3.5 TeV, half the target maximum for the accelerator. Currently the work at the LHC is divided into six experiments denoted by the names ATLAS, CMS, ALICE, LHCb, TOTEM and LHCf. A major current objective for the LHC is the search for the Higgs boson.
How to Use Online Video in Your Classroom It's one thing to talk about Mount St. Helens erupting in science class. It's another thing altogether to watch a video of the mountain's summit exploding into dust. Teachers all across the country are finding that judiciously chosen videos help students engage more deeply with the subject matter, and recall the information they've learned longer. "A lot of students these days expect information to be presented in a flashy, entertaining way, so videos can help draw them in," says Larry Sanger, executive director of WatchKnowLearn, a site that collects education-related videos.
What is 3D Printing? An Overview. You’ve heard of 3D printing from newscasters and journalists, astonished at what they’ve witnessed. A machine reminiscent of the Star Trek Replicator, something magical that can create objects out of thin air. It can “print” in plastic, metal, nylon, and over a hundred other materials. It can be used for making nonsensical little models like the over-printed Yoda, yet it can also print manufacturing prototypes, end user products, quasi-legal guns, aircraft engine parts and even human organs using a person’s own cells. Fantastical? Yes.
40 Sites and Apps for Creating Presentations Creating a presentation or slideshow is one of the staples of any 21st Century Classroom. This is a skill that almost every educator has and is a must known skill for any successful student. It used to be that only programs such as PowerPoint could create presentations. However, now there are lots of sites and apps that not only creating stunning presentations but also make it easier then ever. Below is my list of some of my favorite tools for creating beautiful looking presentations/slideshows.
The 3D Printer Experience Opens In Chicago The evolution of technology has already changed life as we know it. One retail destination in River North plans to make the Windy City known for its support of a growing tech industry that is revolutionizing manufacturing. Beginning Monday, April 22, Chicagoans will have the opportunity to explore this technological innovation firsthand at The 3D Printer Experience (316 N. 3 Free (But Powerful) Presentation Tools For Teachers Teachers are presenters. Let’s be frank. They get up in front of a room of people and present. They then encourage the students to work together and continue the presentation through other methods. in other words, teachers need to know how to present and create slideshows.
