@Eliizabeth - Cars are more forgiving in this regard since there's no danger of them falling off the sky. The consequences of not paying attention to car maintenance are much less severe. That said, it doesn't mean one should completely ignore the ordeal. It's alright if you skip a monthly maintenance check.
I know what you mean, Ann. I am not so great about paying attention to my car--or at least historically I have not been so great. But these days I do try to listen carefully to the messages my vehicle is trying to send me to avert accidents or major breakdowns before they happen. It's a good lesson to learn!
Your comment reminds me about paying attention to engine and other under-hood sounds in one's own car. Since I don't have formal auto mechanics training, sounds in my car tell me things about its condition but not a lot: mostly "happy," "unhappy," or "danger!" On several occasions, this has saved me from an accident or worse while driving, including brakes starting to fail (more than once) and the radiator fan coming off. (Those were the days before I scheduled more frequent service and maintenance appointments.) Anyway, it pays to listen to our machines, especially if they operate in the air.
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.
