I had an E&M textbook like that once...everything was fine until one of the homework problems ended with having to find the dimensions of a solenoid needed to satisfy some condition. I just couldn't turn the ESU's or whatever back into meters and amps. -- Please reply to: | "Any sufficiently advanced incompetence is pciszek at panix dot com | indistinguishable from malice."

Sometimes I think it would do the US a world of good if the rest of the world would stage an "intervention" and stop loaning us money or selling us oil until we admitted our addiction to both. -- Please reply to: | "Any sufficiently advanced incompetence is pciszek at panix dot com | indistinguishable from malice."

Even India is getting in on the space industry. The difference is that none of them are having to prove themselves better than the Russians. I don't see any signs lately that the US is going back to the moon, regardless of units, so at best your comment is an irrelevance. If it ever does, the astronauts may have to bring passports with valid Chinese visas. -- Mike Dworetsky (Remove pants sp*mbl*ck to reply)

He was, I take it, simply valiantly defending the good name of American and British engineering. > American engineers invented Darpanet, a communications network for > defense purposes that leaked out as Arpanet to civilian applications > such as email and ftp; a British scientist at CERN came up with the > hypertext protocols that led directly to the internet, a way to use > the interconnected network for passing, storing and creating > information content quickly and easily.

About 35 years ago I moved to a new (to me) older house in London and needed to replace some damaged floorboards. When all the houses in my area were built they were done in Imperial measurement with boards, as I recall, 5-5/8 inches wide (finished size), or 143 mm. But when it came to buying some new replacement boards, I couldn't find any because timber had been decreed to be in metric cuts a few years earlier. They literally would not fit. So I had to have the merchant trim about 5 mm off the edges of all the 150-mm boards I bought so I could fit them in. (Floorboards have a small gap between them in most houses; normally you would lay your interior flooring on top of them.) My point is that it should have been perfectly possible to measure in metric, but retain the same historic physical size as a stock option, because the vast majority of housing stock used the old size, however you measure it. None of this made any sense to me but some government official had decreed it because he liked round numbers, or because 150mm was some sort of standard continental timber size. -- Mike Dworetsky (Remove pants sp*mbl*ck to reply) |
