Dear Sir/Madame,
Could you please clarify the following - Why is the H-N-H bond-angle in ammonia molecule (NH3) greater than the H-As-H bond-angle in arsine (AsH3)?
-Sruthi.
I hope I'm asking this in the right place. My friend and I are working on a home recording project, and we've encountered an electrical mystery. We've got (a) a mixing board, which is plugged in, (b) powered speakers that are connected to the mixer and plugged in on their own and (c) a laptop, connected to inputs and outputs on the mixer via a RCA-USB hub device, and often also plugged in to the house's AC power supply. Here's the mystery: when the laptop is plugged in, the speakers hum. It's a pretty irritating and inconstant crackly hum. If we unplug the computer, or disconnect it from the mixer, the hum stops. If we move the computer across the room and plug it in far away from the speakers, the hum gets quieter, but we can't get it to go away without disconnecting something.
What in the devil is that hum, and is there some easy trick involving grounding something or breaking a loop somewhere that would make it go away? - GTBacchus( talk) 03:43, 3 December 2006 (UTC)

Does the problem go away if all electrical components are plugged into the same outlet or outlet strip? That may be more important from a hum point of view than the overall ground impedance to an earth ground. If components are plugged in to outlets in different places, the impedance between the ground connections can set up a ground loop such that a small amount of current carried over the ground sheath of the audio cables induces hum. I once corrected a hum problem in a commercial editing studio by getting them to connect all power cables to the same source. Edison 20:50, 3 December 2006 (UTC)
There's an article which addresses the mathematics and probability of humanity going extinct. More specifically, it looks at what percentage of humans who will ever exist have existed. I've seen it before, but I can't find a link to it either at End of civilization or Human extinction. Thanks. -- The Radio Star 04:01, 3 December 2006 (UTC)

Are there any good free programs (Windows or Linux) for drawing molecules in 3D? ChemSketch is the de facto 2D program here, but it doesn't do 3D. At least not that I'm aware of. Please don't direct me to the computing desk. They already sent me here. -- Russoc4 05:38, 3 December 2006 (UTC)
Chemical bleaches work in one of two ways:
(a) An oxidizing bleach works by breaking the chemical bonds that make up the chromophore.
(b) A reducing bleach works by converting double bonds in the chromophore into single bonds.
Which of the above gives more durable bleaching effects?
Thanks very much indeed for advice.
Dear Wikipedia
please can you forward this enquiry to the correct department / person who can answer my important enquiry regarding NO supplements. its regarding Nitric Oxide supplements with regards to penile erections. viagra works by increasing the amounts of NO so will NO supplements work the same way in dilating your vessels? what is the difference? I read several articles on it in your enclopedia but still confused.
looking forward to your prompt reply

How does one discover chrome? Is it a mineable iron substance? How is chrome discovered? How does one expore for chrome and where is it found? Is it a bi-product of what???someother mineral? Does it have to be drilled or is it a surface observation? Where are chrome desposit found? Is it like ore? Does it have magnetic qualities? Can it be detected from aerial surveilance? Where are the world's deposits of chrome. Is it a covering for knives and forks only? Where it used in the world? What are its main contributions to the world economy? Is it of any value in a global sense? How can it best be used? —Preceding unsigned comment added by 61.68.8.152 ( talk • contribs)

Using the concepts of cost and price analysis to build a spaceship from scratch. What to look for from the viewpoint of a government agency and as a contracting officer for the government.
The first thing is you need to know what the payload will be. That is, what are you transporting and to where ? The next thing to decide is the type of spaceship. A traditional liquid fuel rocket is probably the cheapest. Then decide who will launch it for you. Then pick subcontractors to build the components. StuRat 15:02, 3 December 2006 (UTC)
I was wondering recently - which has sold more: any form of mineral water or any form of cola? I imagine that mineral water hasn't been widely available as long as cola has been, since the benifits of mineral water as opposed to tap water were discovered fairly recently (as far as I know). RevenDS 15:38, 3 December 2006 (UTC)
My fridge is broken. It's at -0 something Celsius. Just now, I took out a bottle of carbonated (fizzly) water, and as soon as I opened it, it began to froze, seemingly from the top to the bottom. Is there any explanation to this..? 81.93.102.185 16:43, 3 December 2006 (UTC)
Any release of CO2 really cools things down. Think of a standard CO2 fire extinguisher. Opening the bottle is enough to drive down the temperature below that of freezing sugar water (or beer). -- Zeizmic 23:23, 3 December 2006 (UTC)
An even cooler effect is when glass pop bottles were placed at temps far below freezing. The pop would stay liquid as long as the bottles held. When the bottles finally shattered, the sudden reduction in pressure would cause the pop and glass shards to freeze, mid-explosion, much like popcorn does. Of course, due to the flying shards of glass, this is not something you should try at home. StuRat 08:54, 4 December 2006 (UTC)
I am looking for material concerning how Thomas Kuhn's ideas in The Structure of Scientific Revolutions can be applied to the development of an aspect of science. In other words, I need to use Kuhn's ideas to show how an area of science developed. Thanks!
Recently I was watching a show that was saying how, in the future, the moon will gradually become more distant from Earth. And then I started thinking, how would you go about modifying the orbit of a world, like the moon, or Mars? (I mean, maybe you could move a planet into the habitable zone of a star in order to facilitate terraforming.) I know it's a really fanciful idea, but if we were an extremely advanced civilization, what are some ways that you could move a world? -- Lazar Taxon 17:40, 3 December 2006 (UTC)

A family member of one of my co-workers just recently had a child with a (genetic?) deformity that I'd never heard of and didn't think was possible... The baby was actually born without a brain. The baby was fully formed but has only fluid where the gray matter should be. Does anybody have an idea of the medical term for this condition, because I'd like to read more about it. TIA
Anencephaly is correct. A synonym is hydranencephaly. Milder forms are part of the holoprosencephaly spectrum. Hydrocephalus is something different and much less severe and quite treatable if diagnosed early. alteripse 01:07, 4 December 2006 (UTC)
Why are volcanoes shapes and sizes different?
A "perfect" volcano is conical. However, a portion of the cone can be blown out during an eruption, or smaller cones can form that distort the shape of the main cone. StuRat 08:37, 4 December 2006 (UTC)
Can someone explain the difference between a router and a switch in a home networking environment? (Switch is the new, smarter/faster version of the old Ethernet hub, right?) AFAIK, a router is for sharing the internet connection that comes into your house to mutiple outlets (the equivalent of a cable tv splitter). Is a switch is for sharing the network inside your house? (Like you only had one Ethernet jack in your basement, but you wanted to connect more than one device) Lastly, a router can also be a swtich, but a switch can't be used as a router? And where does a gateway fit into all this?
A recent trip to Best Buy had me very confused. Almost every product box seemed to be marketed at people who already knew what each device did, not explaining what each product did. -- 68.103.154.140 19:39, 3 December 2006 (UTC)
A simple definition: A "switch" can redirect the entire bandwidth of the connection to each port. A hub shares the bandwidth. Therefore, each port on a 1 gigabit switch can utiize the full 1 gigabit bandwidth of each port. Switches replace hubs. A switch is used within a network. A router connects two or more networks together using rules. For typical home networking, the rules are pretty simple. Forward all non-192.168 traffic to the internet and do not forward the local traffic. A router uses name address translation to repackage non-local traffic with routers IP. A router is what connects your cable modem or DSL link (i.e. the ISP network) to your home network. Harware firewalls are implemented in a router. A switch is used to connect all your local computers to form a network. Router, Switch and DHCP are all three separate that are sometimes implemented in single device. I believe terms like "gateway" is more of a description of the routing rules rather than a differnt piece of hardware. Just as "firewall" is a description of the routing rules.

I am an 18 year old boy and wondered what would happen if I took my menopausal mother's HRT tablets? Like. how many and how often would I have to take them to notice anyt differences and what would they be and how long would they last after me ceasing taking the medication- All of this is just hypothetical of course.
over the last few weeks my gerbils have become exceedingly fat and have also started mounting each other even though they are all female. i was wondering if you know why.
thanks —The preceding unsigned comment was added by 81.158.81.209 ( talk • contribs).
I suggest looking into what gerbils and their relatives (rats, mice, hamsters, guinea pigs, degus) eat in the wild, and doing your best to mimic that. Also, let them run free around the house as much as is practically possible. At bare minimum, consider shopping around for a high-quality (and of course more expensive) food supply. Situations where you do not get what you pay for are the exception rather than the rule. Theavatar3 00:58, 4 December 2006 (UTC)
Letting them run around the house isn't advisable, as the may get lost, or at the very least, pee and poop on your carpet. I suggest an exercise wheel, instead. StuRat 08:31, 4 December 2006 (UTC)
thanks for all that but whenever i buy them an excercise wheel or anything else plastic they chew it to pieces within the first couple of weeks. i agree with you though saying its a bad idea letting them out. also i have been feeding them exactly the same for a year or so and nothing like this has ever happened. and yes im sure they're all female.
Well, if I were a gerbil, I would rather be given a quick death than be kept in a little metal cage without reprieve. I feel it to be in error to suppose that because they are small, and don't speak any human languages, that they wouldn't regard life in a cage as being a cruel existential nightmare, as we would.
Also note that I suggested letting them roam free as much as practically possible. If you have no ability or interest in supervising them, of course this amount of time will be zero. Theavatar3 17:24, 4 December 2006 (UTC)
Once the last of her cagemates had died, we thought that Short Tail would feel the same way. And up to her end, she seemed to thrive and enjoy her time out of the cage.
Atlant 13:58, 5 December 2006 (UTC)
well the bottom half is opaque plastic and the top half is clear plastic with metal covered in plastic bars for the roof.
well the last time we got a metal cage it fell off and smashed so thats why we bought a plastic one
I was wondering if anyone knew if the power of a water current changed depending on the depth of the water. also, which depth has the greatest amount of force.
thank you —The preceding unsigned comment was added by 142.68.205.18 ( talk • contribs).
The velocity of water currents do vary by depth, but not in any consistent way. In some locations, the surface currents are the fastest, while in others, the underwater currents are stronger. The directions of the current also may vary by depth. StuRat 08:29, 4 December 2006 (UTC)
Im from the UK and was wondering about the Playstation 3. I know it sounds complex but how does the whole system work? What goes on when you turn it on inside the machine and how does it know what to do? I suppose this applies to all computer and technical innovations, but because the PS3 employs new technology I just wondered what happened, so could anybody enlighten me? —The preceding unsigned comment was added by 82.36.182.217 ( talk • contribs).
All computers (and game consoles) boil down to logic gates. These simply take two inputs and produce an output. For instance an OR gate looks at two binary input values, where a 'one' means a signal is received, and a zero means no signal is detected, and if either of the inputs is one, the output will also be a one. An AND gate only produces a 'one' output only if both inputs are one. You can build an entire computer using only one type of gate, by combining a few gates to emulate the behaviour of other gates.
When you put enough gates together, you may get a machine that can perform useful (or entertaining) functions. The more gates you can pack into a given area, the more potential power a computer has. This is the domain of the scientist/engineer. The real art of computing lies in combining gates in sophisticated ways that will provide sophisticated outputs, such as dynamic video and audio displays that make you think you're fighting in World War II. Some of this artfulness is applied at the hardware level, providing general routines that can be used by a wide variety of applications (i.e. software, games), but most is done by software (or game) developers.
Funny also that the leading figure in computing has the surname of Gates. Theavatar3 01:23, 4 December 2006 (UTC)
Thank you very much for your help, so what is the Blu-ray thingy it has in it. What's so special about it and why is it causing 'em so much hassle?
What is the force exterted on the wall and ground by an object leaning statically against a wall? For example, a ladder leaning against the side of a house. And, how are the force/mass on the wall, the force/mass on the ground, and the angle θ that the object makes with the ground related? -- AstoVidatu 22:45, 3 December 2006 (UTC)
i was thinking of getting into amateur astronomy but was looking round for a telescope but i was wondering if any1 knew the best places to look and what would be a good size for an complete amateurs first telescope (budget £100 ish) and if any1 knew any "good" shops. i did google and looked at some places but i'm a little wary of places advertising specs that sound good but mean absolutely nothing.-- Colsmeghead 23:57, 3 December 2006 (UTC)
I`d like to add this Cols...This might not be important to you, or what the other fine folks here have mentioned but, to me at least, it depends on what YOU want to observe. If you are mainly interested in observing 'static' things, such as other galaxies and stuff, (i.e. far distant 'objects') then SIZE might be what you want. If you`re more interested in things/objects that MOVE, such as the Planets in our solar system, or the Moon, for instance, then I`d aim more towards the smaller, even though more expensive per inch of aperture, refractors. They offer a more detailed/sharper image, and are far easier to carry around than the 'big' ones. Remember this: You get far more use, and enjoyment, out of the `scope you USE the most. If you purchase a telescope that`s so large that it`ll end-up only gathering dust in your basement, or attic, then all your efforts will be wasted. What you intend on spending could surely affect your decision too. I hope this helps somewhat in your final decision...please consider them. Dave 172.135.3.189 02:39, 5 December 2006 (UTC)

I suppose this applies to all computer and technical innovations, but because the PS3 employs new technology I just wondered what happened, so could anybody enlighten me? —The preceding unsigned comment was added by 82.36.182.217 ( talk • contribs).
All computers (and game consoles) boil down to logic gates. These simply take two inputs and produce an output. For instance an OR gate looks at two binary input values, where a 'one' means a signal is received, and a zero means no signal is detected, and if either of the inputs is one, the output will also be a one. An AND gate only produces a 'one' output only if both inputs are one. You can build an entire computer using only one type of gate, by combining a few gates to emulate the behaviour of other gates.
When you put enough gates together, you may get a machine that can perform useful (or entertaining) functions. The more gates you can pack into a given area, the more potential power a computer has. This is the domain of the scientist/engineer. The real art of computing lies in combining gates in sophisticated ways that will provide sophisticated outputs, such as dynamic video and audio displays that make you think you're fighting in World War II. Some of this artfulness is applied at the hardware level, providing general routines that can be used by a wide variety of applications (i.e. software, games), but most is done by software (or game) developers.
Funny also that the leading figure in computing has the surname of Gates. Theavatar3 01:23, 4 December 2006 (UTC)
Thank you very much for your help, so what is the Blu-ray thingy it has in it. What's so special about it and why is it causing 'em so much hassle?
What is the force exterted on the wall and ground by an object leaning statically against a wall? For example, a ladder leaning against the side of a house. And, how are the force/mass on the wall, the force/mass on the ground, and the angle θ that the object makes with the ground related? -- AstoVidatu 22:45, 3 December 2006 (UTC)
i was thinking of getting into amateur astronomy but was looking round for a telescope but i was wondering if any1 knew the best places to look and what would be a good size for an complete amateurs first telescope (budget £100 ish) and if any1 knew any "good" shops. i did google and looked at some places but i'm a little wary of places advertising specs that sound good but mean absolutely nothing.-- Colsmeghead 23:57, 3 December 2006 (UTC)
I`d like to add this Cols...This might not be important to you, or what the other fine folks here have mentioned but, to me at least, it depends on what YOU want to observe. If you are mainly interested in observing 'static' things, such as other galaxies and stuff, (i.e. far distant 'objects') then SIZE might be what you want. If you`re more interested in things/objects that MOVE, such as the Planets in our solar system, or the Moon, for instance, then I`d aim more towards the smaller, even though more expensive per inch of aperture, refractors. They offer a more detailed/sharper image, and are far easier to carry around than the 'big' ones. Remember this: You get far more use, and enjoyment, out of the `scope you USE the most. If you purchase a telescope that`s so large that it`ll end-up only gathering dust in your basement, or attic, then all your efforts will be wasted. What you intend on spending could surely affect your decision too. I hope this helps somewhat in your final decision...please consider them. Dave 172.135.3.189 02:39, 5 December 2006 (UTC)
