So how about an engine that sings? French technicians have programmed the controller for an Asiatech 10-cylinder, 750-hp Formula 1 engine (based on a Peugeot design), to run through various rpm/note ranges in the correct sequence to play a rousing sequence of musical notes. With five combustions per revolution at a frequency per second of 12/rpm [60/(5 x rpm)], the engine can produce revs for a particular note by multiplying the note's frequency by 12. For example, a 440 Hz A note needs 5,280 rpm and a C needs 3,139 rpm. For a demonstration of "When the Saints Come Marching In," go to http://astro.temple.edu/~kmr/Chauffe2.mp3.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
