In a NASA article 'Eclipse Predictions and Earth's Rotation' it states that "The Moon's average distance from Earth is increasing by 3.8 centimetres per year."

I've not heard anything about this before, but knowing a little about how vital our Moon is to our planet it does concern me somewhat, and I'd like to know...

1. Why is the moon moving further away?
2. What effects will this have upon the Earth as our Moon gets further away from us - i.e. on tides, etc?
3. How long will it be before we notice the effects on the Earth of our Moon being further away from the planet?
4. How far away will our Moon go, and what will happen to it/us then?

Thank you.

Hi, i'm having real trouble understanding the schrodinger equations (the time dependent and time-independent), can anyone explain simply what the difference is between the two, and what they are used for ?
Anyone that explains this as simply as possible, and without the use of too much maths will get 10 points.
Thanks, David.

The Indian coastline is so huge and thus I am guessing that there must be thousands of uninhabited Islands around India??? Does anyone know exacly know how many unhabited islands exist around India (inside it's maritime borders because India can only claim those that are inside it's maritime borders) or where I can ascertain such information.

Formula: 1/a + 1/b = 1/f Solve for a.

I know I have to subtract "1/b" to isolate "1/a" but after that, how do I get "a" by itself?
