I have a potential idea for a solution to green house warming. We engineers can design a HEPA type filter with a liquid solution and charcoal filters and absorbers to absord the emmisions from cars and buses. This filter could be installed in the trunk and the exhaust gas would be piped from the exhaust to the trunk and then discharged from the side of the car

If and when we need to escape our solar system how could we create a portable SUN solution to take with us and how would this effect the gravitional requirements of the propulsion systems in place to propel us and break away from our current orbit around our SUN?

I saw a documentary a few years back that mentioned a plan for an array of orbital radio telescopes that would function in unison; and kept in sync with lasers. I think it said it was supposed to be implemented around 2014. Does anyone have any info on this?

Consider the integer 100. It can be completely factored like so:

2^2 x 5^2

Next, consider 3663. It can be completely factored like so:

3^2 x 11 x 37

Finally, consider the integer 31. It is prime, but it can be "completely factored" as just itself, namely 31.

As far as I can tell all these factorizations are unique. Except for the order of the factors, they can be done in one and only one way.

So, prove that the complete factorization of *any* integer into primes is unique.
