App Inventor for Android lets people create apps for Android phones by manipulating programming blocks in a web browser. Since July 2010, Google has run App Inventor as a large-scale public web service as a part of its Google Labs suite. With the wind down of Google Labs, as of December 31, 2011, Google ended support of App Inventor. In order to ensure the future success of App Inventor, Google Research has funded the establishment of the Center for Mobile Learning at the MIT Media Lab. Sometime in the first quarter of 2012, the Center plans to provide a large scale App Inventor service for general public access, similar to the one Google ran. MIT’s will be posting progress on getting their public service up and running at MIT Developer’s Blog .

A coilgun (or Gauss gun, in reference to Carl Friedrich Gauss, who formulated mathematical descriptions of the magnetic effect used by magnetic accelerators) is a type of projectile accelerator consisting of one or more coils used as electromagnets in the configuration of a linear motor that accelerate a ferromagnetic or conducting projectile to high velocity.[1] In almost all coilgun configurations, the coils and the gun barrel are arranged on a common axis. Coilguns generally consist of one or more coils arranged along a barrel, so the path of the accelerating projectile lies along the central axis of the coils. The coils are switched on and off in a precisely timed sequence, causing the projectile to be accelerated quickly along the barrel via magnetic forces. Coilgun Coilgun

Background: This floating bridge, which was completed in 1966, carries State Route 520 from Seattle to Medina, Washington. At 1.4 miles long, it has one of the longest floating spans in the world. Why It's Innovative: Because Lake Washington can be more than 200 feet deep, building a suspension bridge across it was not a viable option in the 1960s. The floating design, which relies on concrete pontoons that are anchored by underwater weights, was the perfect solution. In its more than 40 years of existence, the Evergreen Point Floating Bridge has been battered by high-speed winds and even withstood a barge crashing into it.
