“Thrust is the force that is the opposite of drag. Thrust is the push that moves something forward. For an aircraft to keep moving forward, it must have more thrust than drag. A small airplane might get its thrust from a propeller. A larger airplane might get its thrust from jet engines. A glider does […]
Using just a few household items and some basic science, here’s a simple way to create a cool perpetual spinner.
The nine-year-old Mozart was not, as suspected, a midget adult. This and many other fascinating revelations are uncovered in a collection of historic scientific documents unveiled by the Royal Society this week. The society, formed in London in 1660, began publishing a journal titled Philosophical Transactions five years later – a journal which remains in […]
The crew of the Atlantis shuttle have had a surprise turkey dinner for Thanksgiving. Some sneaky work by staff on the International Space Station made sure they were able to celebrate in traditional style despite the meat not being in the scheduled meals. Space being the one place you can’t currently find a Subway, the […]
“Our Place in the Cosmos”, the third video from the Symphony of Science series, was crafted using samples from Carl Sagan’s Cosmos, Richard Dawkins’ Genius of Charles Darwin series, Dawkins’ TED Talk, Stephen Hawking’s Universe series, Michio Kaku’s interview on Physics and aliens, plus added visuals from Baraka, Koyaanisqatsi, History Channel’s Universe series, and IMAX […]
In the following video, Bill Nye demonstrates a scale model of the solar system by riding his bike across a barren plain. Richard Dawkins wrote this about our planetary system: Find a large open space, and take a soccer ball to represent the sun. Put the ball down and walk ten paces in a straight […]
In the following video, science comedian Brian Malow jokes that a virus is “the ultimate David and Goliath” when compared with humans. He then rattles off a series of hilarious science-related jokes. Enjoy! [Via BoingBoing]
NASA has just release this amazing video showing Earth’s weather from August 17 to August 26, 2009. The clip was filmed at a 7-kilometer resolution with NASA’s GEOS-5 atmospheric general circulation model. The GEOS-5 atmospheric model was developed by NASA Goddard’s scientists. It’s based on the Earth System Modeling Framework, an open source project “for […]
We all know it, traffic jams that seem to happen for no apparent reason is one of the biggest source of frustration for drivers. I can definitely relate to that. Fortunately, dear fellow drivers, our frustration now has an explanation! The phenomenon has recently been re-created for the first time on a test-track by a […]
In order to spark kid’s interest in robotics at an Illinois’ Boy Scout Jamboree, Engineer Dan Toborowski built this amazing accelerometer-controlled marble maze. Check it out: I recently completed a project involving wireless control of a Parallax BOE-Bot using an accelerometer and decided to adapt this system to control a custom-built 2 axis maze assembly.
