Science & Mathematics - 28 November 2007

Okay, so I have to write a two page argumentative essay over a controversial topic.

My topic was the Big Bang, and how I'm for the theory (being a physics major and all).

Well, my teacher decides to flip everybody's sides to where they're against the topic they're for, and vice versa.

So, I need help.

I know of a couple of theories of how the universe came to be. The one I'm most familiar with is the Static Universe theory by Einstein; but there's a problem. His theory was proven wrong.

So I need some other theories that are very possible.

Serious answers, please. Best one = 10 points.

Thanks!

Okay, every one now a day's seem to talk about Nuclear atom craft werks. See Russia, China, North Korea and Iran. What is it all about? Is it really just to create a more efficient way of energy consumption? Or just another way to blow up at each other faces when we do not agree about something? Whats your opinion on that matter?

The first odd number can be expressed as
1=1²-0²

The second odd number can be expressed as 3=2²-1²

The third odd number can be expressed as
5=3²-2²

The fourth odd number can expressed as
7=4²-3²

Write down a formula for the Nth odd number and simplify this expression & prove that the product of two consecutive odd numbers is always odd.

could you show me how you did it aswell please? very confused!

Please can you prove that the if all shapes had the same perimeter that the circle would have the largest area

Also prove that Reg. shapes will have larger area than irregular shapes if they each have the same perimeter.

Please don't be afraid to be long winded or refer me to websites or use Pi or Cos/Tan/Sin although keeping it simple would obvo be nice.

Thanks in advance!

Assuming mankind will not destroy man sometime in the future, to a fatal degree, do you think man will ever discover external life someplace in the universe?

Wouldn't it be interesting to see what time era they are in, and what their lifestyles are like, etc? Assuming they live in an organized, civilized society of course.
