Other - Science - March 2007

MY idea is to have a battery pack that runs on AA's that I can use to charge multiple devices(mp3 player,cell phone, portable DVD player, etc..).

I can use both a dc plug(the kind that plugs into a car) or an ac plug. (would prefer that it used ac if possible).

I would seperately charge the AA's.

Can I just hook up a dc outlet directly to the batteries, because the dc plugs have transformers built in, or do I need to do more?



How do I go about making one of these

If humans evolved from primordial ooze then so did all animals. why aren't they evolving to where we are at? And why are there so many different types of animals and organisms if we all started from the same crap??

I find it unbelievable that even though atheists are only about 5% of the population of the USA (And even fewer of them are scientists), they think they have the right to dispute the biblical beliefs of the majority of Americans who identify as Christian.

Not only that, but they want us to PROVE that the biblical account is correct (it's called faith, liberals). However, they are totally unable to prove these wackjob scientific theories they spout out.

Can someone shed some light on why these "scientists" have any credibility when they recite the lie of evolution, the age of the earth, of global warming etc, especially when it is in direct opposition to the bible. The bible never mentions global warming as being a threat to humans, the threat is the Anti-Christ, global warming isn't mentioned in Revelations. It seems that this is just another case of a small percentage of "scientists" forcing their atheistic lifestyles on the vast majority of proud, hardworking Christian Americans.

I am always shocking people and things. It is not just a once in a while thing. All day to day I have been shocking my self and other people and things.
I understand how static electricity works but why is it consistant for me. I'm not doing much different from other people who don't shock when they touch something. Do you know why this might be?

I had compare the salary range of these careers, physicist got 80,000 average salary, chemist got 65,000 average salary, biologist get 60,000 salary and doctor gets 120,000 average salary. So why do doctor gets more salary than the others? Does that mean that doctors are more smarter than scientist in general?

...without any doubt, experimented and proven by scientists? And how much is still speculation?

And why are there still monkeys?
