Kinda like I did on Cartoon Planet?

That sure would rock to live on one and see planets and moons from your window.

continued....
turn certain elements into others by either taking or removing protons? Is it theoretically possible to turn hydrogen into gold by adding enough protons? Is the reason this is impossible because there would be a release of atomic energy like a nuclear bomb?

I realize this is impractical for wealth-building even if its somehow possible because gold isn't worth much in the (femto???)-technology scale.

Learned anything new? Doesn't "science" mean discovering new things?

With Google Moon you can zoom right in to the Apollo 11 landing site:

http://www.google.com/moon/#lat=0.656107&lon=23.471136&zoom=19

...and the photos see to have enough resolution. Using the scale in the bottom left, it works out to 12 pixels per meter, which should be MORE than enough to see the base and legs of the lunar module that was left behind.

It appears you can see the dust trails of where they walked, unless that's an enhancement added by NASA.

But you can't see anything. I'm NOT looking for wacky conspiracy theories, but an actual explanation (like the photo was taken before Apollo 11, or something concrete).

June and Jeanne leave at the same moment and travel in opposite directions. June walks at 1.7 miles per hour and Jeanne walks at 2.8 miles per hour. How long must they travel to be 28.8 miles apart?

Please just don't give me the answer I wanna learn so if you can give me a step by step process that would be awesome!

I'm in the process of building my first wind turbine and was curious if running it without a load (ie. battery bank) would be harmful to the generators? I'm using a 260VDC 5A permanent magnet treadmill motor as the generator. I'm about ready to put up my tower and wasn't sure if I can go ahead and get it all assembled and put up and then add the battery bank as soon as I can get the batteries. This way I could also see how well it's going to perform on the tower. It's a 60' lattice tower and will be hinged at the bottom but still will be a bit of a pain to lower and raise a lot. I'm really excited about getting this up and running but don't want to damage anything before I even get started.

Also I've heard of people using old electric baseboard heaters as a load dump when the bank gets fully charged. I'm having some trouble locating any of these around here and was wondering if anyone would have any other suggestions on something I could use as a dump? Thanks for all your time.

first of all, all of us got different views to a specific matter...And my question is, why cant people believe that God created the Universe?...Bigbang theory? ftw? planets collided and humans were made?.

Read Genesis chapter 1. God created the Univerese... its just the fact that some people are just ignorant and cant face the fact that God created us with limited minds.

I hate it that they teach that in school about bigbang and etc. kids are misinformed..:(

If ur an atheist, well, i cant blame you if you dont believe in God, or nothing at all,...its just a whole different story with religion..:)

Hi, i was wondering if any of you math-tastic people out there could help me figure out these math problems.

they are part of the chapter called "trig substitution"

1) integral of (dx/[(25-x^2)^(3/2)])
where x=5 sin (thetha)

2) integral of ((25-x^2)^(1/2))/x dx
where x= 5 sin (thetha)

thank you!!
