  • Could No 'Boom' Mean a Big Boom for Business Aviation?

    What NASA called a “breakthrough” in wind tunnel testing could soon take the “boom” out of supersonic flying, and scientists at the Dryden Flight Research Center believe it could benefit business aviation in “years rather than decades.”

    Face it: The biggest reason that business aviation hasn’t gone supersonic yet is the sonic boom. Even when supersonic aircraft fly at high altitudes, that big “ka-BOOM” has proven so unacceptable that supersonic flight has been banned over populated areas for decades.

    However, NASA has hailed recent wind tunnel tests of supersonic models designed by both Boeing and Lockheed as breakthroughs.

  • 9 Year Old Boy Proves to Be a Future Engineer

    Meet Caine. He is a 9 year old boy who built an elaborate cardboard arcade inside his dad’s used auto part store. According to Caine’s father, he spent at least a year building this arcade and his first and only customer happened to be filmmaker, Nirvan Mullick.  Mullick was so impressed with Caine’s arcade, he decided to compose a short film on Caine’s story and how he continued to construct his arcade even though there was no audience.

    Mullick’s video hit the social media waves and started attracting attention so he decided to start a scholarship fund for Caine on the official Caine’s Arcade website: “Chip in $1 or more to help Caine to go to college. Imagine what this kid could build with an Engineering degree!”

  • New Way of Lasing: A 'Superradiant' Laser

    ScienceDaily  - Physicists at JILA have demonstrated a novel “superradiant” laser design, which has the potential to be 100 to 1,000 times more stable than the best conventional visible lasers. This type of laser could boost the performance of the most advanced atomic clocks and related technologies, such as communications and navigation systems as well as space-based astronomical instruments.

    Described in the April 5, 2012, issue of Nature, the JILA laser prototype relies on a million rubidium atoms doing a sort of synchronized line dance to produce a dim beam of deep red laser light. JILA is a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder (CU).

    JILA/NIST physicist James Thompson says the new laser is based on a powerful engineering technique called “phased arrays” in which electromagnetic waves from a large group of identical antennas are carefully synchronized to build a combined wave with special useful features that are not possible otherwise.
