or is it all prety much surveilled —Preceding unsigned comment added by 212.51.122.27 ( talk) 00:24, 9 February 2008 (UTC)
Do we have a space station orbiting the moon?
(Just to make sure, my understanding is that we don't have one on the moon, and we don't have one either obiting nor on Mars. Is that right?)
Thank you! —Preceding unsigned comment added by 212.51.122.27 ( talk) 00:37, 9 February 2008 (UTC)
If you see someone with Pernicious Anemia which unbeknownst to you is due to a vitamin B12 deficiency, and you give them a folate supplement, their anemia will resolve. Will they still have homocysteinuria?

it's not homework, just something i found in the maargins of my physics textbook. ^^; —Preceding unsigned comment added by 202.156.88.207 ( talk) 07:21, 9 February 2008 (UTC)
What are snail offspring called? Issi5690 ( talk) 10:09, 9 February 2008 (UTC)
Bob, Jemima, or, more famously, Brian, but really, pretty much any name the parents like. Except, I hear that modern snail parents have an irrational aversion to calling their offspring " Snoop Doggy Dogg" on the basis that it's too silly (although Snoop Dogg is apparently acceptable). -- Dweller ( talk) 12:45, 12 February 2008 (UTC)
hi friends,
i m trying to model the thermoacoustic refrigerator as given in the link:
www.kettering.edu/~drussell/Publications/ThermoDemo.pdf
in this article it is given that a fundamental harmonic is to be established in the resonator(quarter wave) tube and then the power of the speaker is to be increased to such an extent that a second harmonic is barely audible.i m unable to recognize that a second harmonic is heard.rather the incident sound is so high that it is impossible to hear any other sound.any friend with some knowledge on waves.help me.

sir,
thank you very much for your answer.if you went through the article .you must have read that there is a need of a thermocouple in it.i live in a remote place,so no thermocouples with me.
i m trying to measure the temperature with a metal pin inserted in the resonator such that it touches the stack at a point which is expected to get colder.and then a labrotory thermometer touching it.i am not sure about its working can any one help.

Hi! When I was little I read a set of volumes of books called "Stories of Science" (it was a Hindi translation actually). It gave detailed and fascinating historical accounts of how various discoveries and inventions of science were made and what the people involved went through, and the even the politics involved. I don't have those books any more. Can anyone suggest a similar book(s) that gives an interesting, historical account of the stories of science? Thanks a zillion :) ReluctantPhilosopher ( talk) 15:35, 9 February 2008 (UTC)
What is the difference between a penny and a penny? Thank you! —Preceding unsigned comment added by 79.122.70.107 ( talk) 16:16, 9 February 2008 (UTC)
It is 0d in old money, 0p in new money and 0¢ in American money. SpinningSpark 16:23, 9 February 2008 (UTC)
Uh, there is no difference between a penny
ok, I'm the OP -- I was just interested in what kind of answers you would give. In fact, you have given answers in terms of a pun, materials science, and finance (currency). But not mathematics (the difference [ie if you subtract the latter from the former] is "zero") or Grammar (the word's place in the sentence - as the first or second object of the preposition "between", perhaps inflection falls at the end of a sentence too...). Surprisingly, no one gave the answer that I was expecting people to give: "Nothing" -- there is no difference between a penny and a penny. —Preceding unsigned comment added by 79.122.91.85 ( talk) 23:37, 9 February 2008 (UTC)
Please tell me why High Tension electric cables(overhead) buzz?? A conspicuous very much audible buzz is found below such a cable..

Looking out of my window as I drew the curtains this evening, I noticed the crescent moon in the sky. I don't normally spend a lot of time looking at the moon, but tonight's moon is strange. Despite it being a crescent moon, I can still see the entirety of its face. The proportion of it which should be fully in shadow is actually slightly brighter than the surrounding sky and shows up clearly against it - dark grey on black, to put it simply (I know the sky isn't *really* black - but near as dammit). I live in Northern England, if anyone from my part of the world wants to have a look out at what I'm talking about (it's still doing it now as I type this)...
What's going on? I can't recall ever seeing a moon like this. Unless I just haven't been paying attention (taking the moon for granted?) for all these years. -- Kurt Shaped Box ( talk) 18:44, 9 February 2008 (UTC)
Another and more picturesque name for the phemomenon is Old moon in the new moon's arms (that's also a redirect to Planetshine). It is very common for it to be visible when the moon is a thin crescent, but only when the sky is also dark, and when it's a thin crescent it's mostly in the day sky, not the night sky. --Anonymous, 01:08 UTC, February 10, 2008.
Hi. I'm just wondering, what is the colour of the average clear sky on Earth during the middle of the daytime excluding the colour of the sun and clouds and moon and dark areas and haze and terrestrial objects and aircraft and contrails and lightning and halos and all other objects' colours in the sky other than the average colour of the daytime sky itself, in HTML? Thanks. ~ A H 1( T C U) 19:07, 9 February 2008 (UTC)
