Scene isn't Green in U.S. Auto Market

Regarding the Detroit Big Three's efforts to befriend the Earth,
the question seems to be if it will happen, not when.

By Jeffrey Rowe

Jeffrey Rowe photoYou would think that by now the so-called Detroit Big Three automakers -- Ford, General Motors, and Chrysler -- would have jumped on the green bandwagon to develop smaller, more fuel-efficient, easier-to-produce vehicles. After all, not everyone wants a vehicle that weighs 6,000 pounds, produces 500 horsepower and foot pounds of torque, and gets 12 miles per gallon of gas.

Ford, GM, and Chrysler do offer a few hybrid models, mainly trucks, SUVs, and crossovers. This is great news for fuel-conscious customers of these larger vehicles, but how long will the market have to wait for a U.S.-manufactured contender to take on the smaller Toyota Prius, Toyota Camry, or Honda Civic hybrids? My advice: Don't hold your breath. The Big Three have a subpar track record in the green arena, and that seems unlikely to change any time soon.

Publicity, Not Profit
As much publicity as hybrid vehicles have received, the attention hasn't exactly translated into huge sales. As a matter of fact, all combined hybrid sales in the United States last year only accounted for a little more than 2% of all new cars and trucks sold, and Toyota, Honda, and Lexus models enjoyed the majority of those sales. However, hybrids accounted for almost 11% of Toyota's U.S. sales last year. Little information is available about how hybrids are selling for the Detroit Big Three. "No word" from Detroit usually means slow sales, and I'm sure that's the case here.

Why hybrids haven't been better sellers is something of a mystery, but is probably directly related to their higher cost compared with conventional models and the payback time required to offset the additional up-front cost. Most potential automotive customers still regard hybrids as a novelty, not yet worthy of serious consideration.  Read more »

Cadalyst Labs Review: Mathematica 6

By Mike Hudspeth, IDSA

How many times have you heard people say, "How hard can it be? It's not rocket science"? They might be correct most of the time, but what if it really is rocket science or some other high-end math problem? What will you do then? If you're like me, you'll stand there a minute with a glazed-over expression on your face, you'll scratch your head, and then you'll figure out a way to either find someone else who knows how to do math of this kind or come up with a more empirical way to figure it all out. Another alternative would be to fire up your copy of Mathematica 6 from Wolfram Research.

Mathematica 6 is a computational engine par excellence. It can handle just about any kind of complex math you can throw at it. It's for the big dogs (mathwise). Colleges and universities use it to further science and mathematics as we know it -- and with a pedigree like that, it's got to be good. And it is.  Read more»
