I found these maps on world flooding in 20-40years. Due to rising sea levels ( down to global warming - not necessarily from carbon polution)
Most of the good cities are gone :(
the main cities submerged are in white.

Recent studies have shown that aging can be delayed. If it can be eliminated, do you want to live till you are a very very ripe 1000 yr old man or woman?

I would like the formula for the following:
say i invest $1000 in a fund every year, assume the annual return rate is 10%, how much do i get after 10 years?

I know the formula is : C x ((1+r)^n-1)/(1+r)) x (1-r)
and I would like to know how to come up with this formula??
Is it formula of compound interest + Geometric series??
can anyone elaborate for me? or give me a website to find out the answer??

thanks

There was a Lunar Eclipse on the 27th August and in Brisbane Australia, we had an incredible view of the whole eclipse. It started at 7PM and ended at about 10PM

The moon actually did turn an amazing colour red. I guess we were lucky to be in the right place at the right time.

The next, likened to this one, is due in 2011

doing a little Googling, I ran across this site....the table on that page explains the sidereal and synodic periods.... it has confused me greatly....but... what I noticed was that the inner planets' keep the same face to the sun, as the moon does to us, both Earth and Mars have nearly the same day length, and then you hit the gas planets and the cloud movement around them goes crazy fast, then get us to the outlying planets and they're crooked and spinning like wild!.... what's bothering me most is why the change from spinning to nearly NO spin the closer you get to the Sun?... and what good reason is there, then for both Earth and Mars to be on basically the same period.....

would the Earth spin be connected to the hit that brought us the moon?... should Mars be turning faster?.... and why DOESN"T the moon revolve...is it it's proximity to Earth?... and that's what's up with the inner planets?....

I thought it strange that there's two of each, too...thanks for ideas....

mowing it regularly, and if you have acres of it, and if you harvest it and grind it to flour, could you make edible bread out of common grass...?

Yes, I KNOW that wheat, oats, rye, corn, etc., are better and have been bred (no pun intended) for the purpose. But would it work? Anybody know or heard of anyone who's tried it? Would it taste nasty...? I know cows, horses, etc, will eat it, but I don't think they have very discriminating palates.

I don't have the time or space to experiment with this. Please, serious answers only! Thanks.
