Today's No-Problem Problem concerns the interaction of basic engineering,
economics, baseball, and perhaps any number of other disciplines. As in all our
No-Problem Problems, the trick is to spot the inconsistency, insufficiency of
variables, or violation of physical law that makes it impossible to solve the
problem as stated. The winner will be chosen at random from among the most
correct, most incorrect, and/or most interesting entries, and will receive a Design News MagLite™ flashlight.
Here is the problem: "The Baseball Commissioner has just vetoed, 'for the good of baseball,' a trade between the New York Yankees and the Los Angeles Dodgers in which four design engineers were to be swapped for a purchasing agent and cash. The Commissioner has asked you to determine the proper exchange rate for major league design engineers and major league purchasing agents. What is that rate?
So tell us: why can't this problem be solved? Send your answer to: No-Problem Problem Contest (Major League Swap), Design News, 275 Washington St., Newton, MA 02458 or e-mail firstname.lastname@example.org.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
