There are some exotic materials that engineers (and mechanics) wish scientists would find an equivalent replacement material for.
Such instances occur when repairing or servicing equipment that, when hunting for spare parts, it is found that what is needed is made from a meterial known as "UNOBTAINIUM".
No engineer (or mechanic) actually knows what "Unobtainium" actually looks or feels like because it is so exotic and rare.
However, compnents are apparently made from this stuff, and apparently the older the age of a manufactured item, then the odds of some component part being made from "Unobtainium" increases.
By comparison, Chinese scientists have managed to create a new type of metal that has the strength of Chese, is impossible to tap a lasting screw thread into and corodes in unbelieveable time when exposed to Carbonic Acid (Rain Water).
Western motorcycle owners and mechanics refer to this metal as "Crapite".
Panzer..I know exactly what it is..it's when I work on a 20 year old Tektronix oscilloscope, and the chip that fries is obsolete, and no longer in the supply system....Then, you find a vendor that bought all of the old chips surplus, and is now willing to sell you said chip, for more than the oscilloscope is worth, or for what a replacement would cost..
Our biggest problems come from older systems (I contract with the USAF) that are computer controlled, with such modern languages as Atlas, Mate, Unix, and the venerable HP Basic..One must have these interface chips to keep the systems running, and the owners don't want to pay someone (if they could find an old fart like me) to rewrite the program for more modern interfaces...
Which is why, at work, I have to know HP Basic, DOS, Windows 95, XP, Vista, and how to integrate this crap (running from a 386 PC (yes..it runs our microwave measurement system and power sensor calibrator) to the latest vista laptop running the nextgen softeware)....
I'm 54, my goal is to be able to hook up a voltmeter to a calibrater, put in 50 volts, and voltmeter reads 50 volts..
But, at least my job is secure, no one else here knows how to do it...
