Science & Mathematics - 11 November 2007

I need to connect the ground terminal of the potentiometer volume controls I installed on two speakers. One speaker has a metal case, can I use that for ground? The other speaker has a wooden case and is hanging on a concrete wall. What could I use for a ground there? Could I nail a nail or screw a screw into the wooden case to use as ground?

According to many prophets going back centuries this is the day the world will change...or end. The new book found that they believe to be the work of Nostradamus says this is the day the sun, earth and exact center of the milky way will align. Something that only happens every 15,000 years (its been 14,995 apparentley) sunrise on Winter Soltice is that time. Edgar Cayce believed there would be an alignment of the solar system that would shift the world on it's axis, causing the oceans to move, Japan to fall into the ocean and the Great Lakes to empty into the Gulf of Mexico, The Hopi Indians also believe the end is near and don't forget the Mayans. They predicted it first, the Mayan calander stops at December 21st 2012. So sunrise on 12-21-12 I'll be in front of a roaring fire, roasting marshmallows for my s'mores, drinking hot chocolate with baileys in it! Ahhhh, I can hardly wait! What do you think will happen (if anything) on December 21st 2012????

Be honest, is it hard to find a profitable job with this subject?
Do you regret your choice?

If you do, were they created by separate big bangs or just one very big bang...and is it possible that one may switch through these universes by distorting time and space?

Sorry if it may sound stupid, I'm just a high school student so go easy

There are electrostatic air filters but haven't seen a carpet cleaner. Carpets are major harbourers of mites, dust and grime and sweeping and hoovering would seem to increase the static charge of the carpet. If you passed an electrostatically charged element over the carpet the undesirables would cling to the element which could then be discharged in the rubbish. My degree from Dogpatch Insititute of Technology isn't enough for me to reason the whole idea out.

If you know you have a terminal illness where your body doesn't function but your mind does, would you want to be put out of your misery? Or, would you want to linger and suffer?
After all you wouldn't let an animal suffer would you?
