Don't forget to add the "Stop for pedestrians" zones in the middle of most blocks on college campuses to the inefficient stop conversation. I wonder how much greenhouse gasses are added to the atmosphere because of these feel good zones.
The whole problem is that if the politicians admit that it was a mistake, that they will be expected to correct the problem. So nobody in Michigan politics admits to ever making a mistake. That is probably a political thing, I suppose.
Nobody will acknowledge that the four way stops reduce fuel economy, increase pollution, and make the intersections less safe. So that problem does not go away either.
We have lots and lots of four way stops, and a few 5-way stops also. In addition we have the "Michigan Flip" arrangement for making left turns on almost all divided roadways, residential or main. And no oil production anyplace to be seen, although there are some old wells that are not working. So please don't blame the oil companies for municiple government stupidity. They are the same fools who claim that stop signs at every single corner prevents speeding.
The problem with drivers in Michigan is that if you can pay the $16 you get a license, if you are over 21 years old. If you fail the written test they tell you the right answers and then give you the license. It seems that driving is regarded as a right, not an earned privaledge. And so we have a whole bunch of people who have no clue as to how to merge and are unable to focus their attention in order to drive safely. In addition they simply don't understand anything about inertia or friction, and how that relates to stopping a vehicle.
In addition we have a good number of folks with the classic "17 second reaction time" symdrome, and they often make for some real excitement on our roadways. And those snow-bird-brains are one more reason why I would nevber ever visit Florida again.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
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.
