I was working with area and perimeter today, and I noticed that a rectangle can have an area of 8 sq. units and perimeter of 12 units. Then a square can have an area of 9 sq. units and perimeter of 12 units. What I don't understand is how can the perimeter be the same, but the area is different. If I were to cut a piece of string and tie it in a knot, wouldn't it fit around the same amount of blocks (representing area)? This is driving me crazy. I don't understand why it can be different. Can someone explain this to me so that I can sleep tonight?

How does a dichroic filter work? Specificaly how does it reflect certain wavelngths and pass other wavelengths. I think it passes wavelengths because these wavelengths do not match the energies of certain electron orbitals. could you provide a fuller explaination. thanks

There is a diference perhaps in the level of thinking- common fortune tellers/clair voyants see the concrete things and prophets can see events and trends in the time flow.

I am writing a script about a computer Earth installation deep in space that simulates things and creates them on Earth. i.e tests the plausability of humans and decides to wipe them out. There is a sole creator of Earth on Model Earth.

What is the scientific plausability of a second Earth and divine creator and how can I make my story more interesting?
