I read earth’s moon is the second brightest object in the sky after the Sun. Moon shines as it reflects the sun light so do the earth and other planets. Why then the moon shine maximum (is brightest)? Does its rocks have better reflecting rocks or what?

Swapnil s asked a question a about a week ago regarding the volume of a trapezoidal boat. I read the answer, which really wasn't a totally accurate response to the question asked.

The response stated that a trapezoid was a 2-dimensional object, which it is, and it only would have an area. But Swapnil s was talking about a boat...which has depth and therefore a volume could be calculated.

The formula to calculate the volume of a prismodial section is:

V=L/6*(A1 + 4Am + A2)

L-distance from A1 to A2
A1-Area of the front face
A2-Area of back face
Am-Area of a section taken from the middle

This formula is developed from Simpson's rule and used a lot in surverying to calculate volume.

It can be clearly seen flapping, yet there's no atmosphere on the moon.

Now I believe that NASA DID land on the moon, but, how can the flapping flag be explained?

I'm trying to compare the advantages and disadvantages of using a steam jacket on a reactor vs. an external heat exchanger. The steam jacket would be directly heating the reactor and the external heat exchanger would be heating the two inlet streams to this reactor. Please give a few advantages and disadvantages to each.

In about 2000 or 2001, I watched a very thorough documentary of the Apollo space program on PBS. It was about 8 hours long, and was NOT the fiction / drama program. It included interviews with the people who were there and made it happen. I especially remember the account of the HUGE rocket (now on display at NASA in Houston) that launched the moon landing. It was created by german scientists, and due to Kennedy's push to beat the Russians, there was no time to test any part of it prior to the actual launch.

Does anybody remember this documentary? Can anyone tell me what the name of it was so I can buy it on DVD?

If so, the frequencies consist of electrons (mass) jumping from atom to atom -- right? So how can mass pass through our bodies seemingly harmlessly? I've noticed that the higher frequencies tend to be the ones that do harm us. What is it about the speed of a wave that damages our bodies? Is it the frictional heat of the atoms having to slow down so quickly when they reach our "denser than air" bodies?
