  1. Results of extensive research in the UK into this: on US Students Struggle With Understanding of the 'Equal' Sign · · Score: 0

    Ok, so this is not statistically meaningful, but from a sample size of two students (well, my kids) here:

    The elder got the question in two seconds and filled the parenthesis with a 7 within 5. No help.
    The younger couldn't "get" the question, even with some prompting, and filled the parenthesis with 11.

    They are eight and six years' old; neither are especially mathematically talented, but put in more than average effort according to their teachers on that subject.
    Both go to the local (non-private average-sized) school.
    I'd think (i.e., place a small bet on it) around half the 7-to-9 year olds at that school would be able to "do" this problem correctly.

    How old are these "middle grade students" in the study? This kind of age? I can't see it in TFA.

    Actually it's an increase in the frequency bandwidth that get's you higher capacity, not the increase in the actual carrier frequency.

    Agreed, you AC, you.

    So the higher the frequency of your signal, the more bandwidth you can get.

    I'm sorry, but this is just wrong. The higher the bandwidth of your signal, the more data (symbols viz. Nyquist) can be sent.

    If one were to use Single Side Band transmission, for example, the carrier could be at 76Hz and, using simple Amplitude Modulation this could be extended towards say 60GHz, giving, well a Freeking Large symbol rate.

    Of course, doing this would interfere with every single electronic and probably every single electric item such as I dunno, a 60Hz light bulb. But it could be done, says Mr Tesla.

    I'm going to agree with you here: the plots look like the kind of thing that a school kid could write for (say) an Acorn Atom c. 1982.

    Bhutt it's easily done; I did almost the same myself in an important exam at 18:

    "What is the velocity of the hour hand of the clock?"

    "Easy" I thought: 2PiRadians/hour. Wrote it.

    Then I exited said exam and immediately thought:
    "F*ck!"

    /Informative/, to me, means "provides useful information". It should not mean /Opinion/, he said, passing an opinion.

  12. Re:1.6 Horsepower vacuum cleaners? on New Electrode Lets Batteries Charge In 10 Seconds · · Score: 0

    The GP is correct: Power is measured in watts, and "one horsepower" is 740-ish of them.

    Current, on the other hand, is measured in amps.

    You could have said "[] cleaners' motors draw a number of amps, and here in the US with our 120v mains, you'd need at least a 10amp motor..."

    But, you cannot say "[] cleaners are rated in Amps of power". Makes no sense.

    Why the parent is rated Informative is anyone's guess.

    A suicidal person on the brink of killing themselves is - indeed as you write, and I paraphrase - not really in a position to make a rational judgement.

    However (and I speak from personal experience and 25 years of on-and-off "being there", for which I have professional help), such a person is not necessarily as you suggest.

    Sometimes the pain is too much.
