    They tell you not to put metal in it because you probably don't know how to do so safely and so will end up doing yourself, or your oven, a mischief. They think that if you don't do it at all, you can't possibly do it wrong. If you want to try, remember microwaves are radio waves (they're about 12cm. IMMSMC) and obey all the usual laws of radio waves. Read some advanced physics textbooks and you'll learn how to put metal objects in a microwave oven without getting the usual light show.

    To summarise the physics: metals, being good conductors, tend to get a current induced in them; so does water, but, not being a perfect conductor, it also gets a potential difference across it and the old "volts * amps = watts" thing kicks in. Hence why food gets hot in the microwave, and why filament light bulbs glow in the microwave. Air is an even worse conductor, and the potential difference across the air between a piece of electrically-charged metal and the earthed oven wall might well be significant. (And no, disconnecting the earth in the plug won't help. You'll just make the oven body live. Damn those Continentals with their lovely Schuko plugs that have no fuse and will fit into a non-earthed socket with nary word of a warning. At least the worst thing that can happen in this country is that you'll plant a bare foot on a 13-amp plug in the dark. Actually, make that a socked foot; lovely fibre fragments driven deep into the wound by the sharp-edged brass pins). Once you get a PD greater than about 3MV/m (or 3kV/mm, whichever comes first) air tends to make like a metal-oxide varistor and suddenly go from being a terrible conductor to being a really good conductor. Hence the fireworks.

    Someone recently wrote a letter to my local paper suggesting that interest rates on savings should be pegged at least 1.5% above the rate of inflation. That sounds to me like a recipe for high inflation. After all, the only thing that causes inflation, is inflation: things get more expensive so people demand a pay rise, and then having to pay workers more makes things get more expensive.

    I have a much more sensible idea. Peg the value of currency to a commodity. Not a capricious commodity such as gold or silver (which really worked in the past ..... NOT), but a stable one whose intrinsic value is unchanging: energy. As the energy efficiency of industrial processes increases, a kilowatt-hour in the hand becomes more valuable (since it will pay for a greater quantity of efficiently-manufactured goods than inefficiently-manufactured ones).

    Also, it would mean that instead of taking banknotes to a bank and exchanging them for gold or silver, people would be able to take just about anything that burns to the Sociedade Municipal de Iluminaçao e Traçao and exchange it for electricity meter tokens!

  4. Re:Spelling should reflect the pronunciation on Giant Microwave Turns Plastic Back to Oil · · Score: 1, Offtopic

    English has borrowed words from the languages of every other nation that either invaded, or has been invaded by, Britain throughout all of history. And, of course, all these people had their own peculiar spelling rules (the Spaniards even started a civil war over how to pronounce the letter "J". The "ch-as-in-loch" faction won and promptly revised everything to make it look as though it had always been that way. This intensely annoyed the "zh" and "y" factions, who still occasionally lob the odd bomb).

    English also has apparently many more words than the languages of neighbouring countries. This is because we have assimilated words for the same thing from different languages, and then assigned subtly different meanings to them. For instance, in most languages, the word for an animal and the meat that comes from it is the same. But in Feudal times in England, the peasants (who spoke the Germanic-derived Anglo-Saxon language) were breeding animals which ended up on the tables of the aristocracy, who were speaking the French-derived Norman language. On the other hand, English relies heavily on pronouns and auxiliary verbs rather than using inflection (the exceptions being the third-person singular present tense, which takes "-s" or "-es", the past tense which usually takes "-ed", the past participle which usually takes "ed" and the present participle which takes "-ing".) The present participle can also be used as a gerund; however, there is little merit in explaining such things. Fully conjugating a verb in English -- except "be" and "have" which are highly irregular (except in the South West, where they say "I be [or rather, Oi be], you be, he/she/it be, we be, you be, they be), but that is the case in most languages; indeed, any race in whose language the verb "to be" is regular are intrinsically untrustworthy -- requires only four or five different words (not including the pronouns and auxiliary verbs, which are shared). However, for the purpose of counting vocabulary, inflected languages consider all inflections as being the same word.

    And you really should pity the French: they have to use inflection and pronouns (je suis, tu es, il/elle est, nous sommes, vous êtes et ils/elles sont) whereas in Spain they manage with just soy, eres, es, somos, sois y son respectively. Of course they do have pronouns, they just aren't usually necessary and are just used emphatically; for instance, "yo te amo" as opposed to just "te amo" means more like "It is me who loves you".

  10. Obvious why sales are slowing on Is the CD Becoming Obsolete? · · Score: 1

    It should be obvious to anyone who understands their history why CD sales are slowing down.

    In the beginning was the LP. And we bought our music on LPs, and transferred it to tape (reel-to-reel at first, then cassette). In fact, if it hadn't been for someone wanting to link a record player and a tape recorder together sometime in the 1960s, there would be no AJS318 writing this; but I digress. We had our LPs. Some of them were good, and some of them were crap. And we had our tapes, including quite a few made from other people's LPs. Some of them were so good that we went out and bought our own copy of the LP straight away. LPs by design had a limited life, and many consumer-grade record players did little or nothing to prolong that.

    We also had 45s; but these were mainly bought by a younger, more impatient market segment who had to have the latest song now and couldn't wait for it to appear on a long-player. Singles were also bought by those who liked a particular song but couldn't afford the full album -- or had already listened to it and decided it would not be worth buying for one song! The other main market for singles was with the amusement machine hire companies, for stocking juke boxes in pubs, cafés and leisure centres.

    Then came the CD, and we began buying our music on CDs. Not everyone was convinced at first. Some of us began buying music on CD that we already had on a cassette made from somebody else's LP, or on an LP that we owned but which was beginning to sound worn-out. It's worth mentioning that the early CD players, even consumer-grade ones, tended to be well-made and put out a high-quality signal. Like the first transistor amplifiers a quarter of a century before, they represented a technology that had to prove itself in the marketplace; and the only way for the CD to succeed was to be noticeably better than the LP. One of the CD's distinguishing features was the provision of copious sleeve notes that had previously been associated only with some of the better LPs. While the page format is smaller than an LP cover, a standard CD case can hold a 16-page glossy booklet and a modified one can hold a whopping 32 pages. That is plenty of room for the full lyrics, band photographs and production notes -- and by design, it is difficult to reproduce well.

    At this point we also ought to remember another important difference. The CD had an 80-minute maximum running time, as compared to about 45 minutes for an LP. Although it was possible to get over an hour of music onto an LP, this came at the expense of signal strength (and therefore quality) due to the need to pack the grooves more densely. Where in the past, a record producer might have had to make tough decisions about what to include on an LP and what to leave out, with almost double the space available on a CD there was a temptation to fill it all. This brought about a paradigm shift in album production. And whilst CD singles existed, CD juke boxes were designed from the outset to be capable of being stocked with albums.

    Then came a generation of smaller and smaller hi-fis, made possible by the omission of a turntable. Some of us began buying music on CD that we already had on LP. Around this time, manufacturers also began cheese-paring; using cheaper components, polyester capacitors instead of ceramic, unshielded cables, tinned connectors instead of gold-plated, single PCBs instead of separate analogue, digital and power boards. The CD was officially no longer in competition with the LP, and it no longer had to try so hard to prove itself. (Cf. what happens to some people when they get into a stable relationship and therefore no longer have to advertise their availability to potential mates.)

    In the light of which, I think they've done a great job summarising it. Yes, the GPL has various subtleties (like, you can sometimes modify software and keep it all to yourself) but they don't apply most of the time. And the GPL isn't the only Free Software / Open Source licence (the terms are about as interchangeable as "Alsatian" and "German Shepherd Dog"; can you point out something that is one but not the other?

    Student loans in the UK are being privatised and sooner or later will be exactly the same as any ordinary loan ..... if not more expensive, on the basis that the privatised loan company has a captive audience (same reason why a cup of tea in a motorway service station is so expensive, there's nowhere else to get one).

    If you have savings and a loan, even if part of the loan isn't attracting interest because of the savings, you'd still be better off without the loan. The only exception would be if you're tied in with early repayment penalties or some such.

    Your loan of £L attracts interest at the rate of £(L * r1) per annum (note, here r1 is expressed as a fraction, not a percentage; i.e. 0.0725 rather than 7.25%). Your savings of £S earn interest at the rate of £(S * r2) gross per annum. If you use an offset account, then your loan attracts interest at £((L - S) * r1) per annum, saving you £(S * r1); but you miss out on £(S * r2) of interest. So the difference is £(S * (r1 - r2)) p.a. Since r1 > r2 just due to the way the banking system works, you'd be better off offsetting even if you didn't have to pay tax on the interest accrued by your savings. However, offsetting does not alter the term of your loan. If, instead, you simply made a capital repayment of £S against your loan, you would still be paying the same £((L - S) * r1) interest per annum; but the difference is, you only have £(L - S) outstanding now, and so could end up paying it off sooner. Then it won't be attracting any interest .....

    Higher-rate tax is a bit of a red herring. If you never even earned the money in the first place (e.g. because you had no savings due to having spent them on a repayment on your loan instead), you can't be taxed on it! Penalty fees may apply for early repayments; but if you end up making a saving which better than covers the fee, it's still worth it.
