My son is doing science work and he is having trouble figuring out how to calculate the moisture content in the atmosphere. He has the temperature and the pressure figured out, but the moisture content is giving him some trouble.

Isn't there a mathematical way besides trial and error or dividing 4096 by 8 until you get to 8. I need some help explaining this to my GED students.

What has caused all these terrible winds around London, and probably around the UK...? Three trees were blown down near my school and i was just wondering what has been causing these winds to even reach up to 170 km an hour over the past few days. As far as i can remember there were never used to be as strong winds as there have recently.

I heard there are only a few hundred left in the wild. But this is a huge cat! Some have been known to weigh nearly 1/2 of a ton and have a length of 10 ft. including the tail. These Big Cats need Big territory sense they are not social animals. I would like to see the numbers increase but alot of people are afraid of them and alot of them have been killed because of how the cats have come into contact with more and more people moving into the cats territory. Of course this is no Cat to take lightly! Because it has been know to eat fully grown brown bears! Hopefully people will quit killing animals just for the fun of it or for their fur. Thats just wrong!

I recently came across Francis Collins book, __The_Language_of_God, where he lays out an outstanding case for Theistic Evolution. This coupled with similar views from one of my all time favorite authors, C. S. Lewis, has left me on the fence for this issue. I've started on Richard Dawkins _The God_Delusion_ and am also reading Lee Strobels _The Case_for a_ Creator. Leave some suggested readings with your answers. Thanks!

So I'm a bizarre nerd and I want to transcribe my handwritten math notes to a Word document...

I've done searches and found lots of graphing calculators online, even some that purport to do polar coordinates, but I guess I'm not advanced enough to figure them out--graphing calculators were just being invented when I first took higher math and this is my second time around!

Right now all I want to do is type in a set of polar coordinates given in examples by my professor and have a graph spit back at me that I can screen capture, crop, and put into place in my notes. I don't need the calculator to do anything fancy like loops and circles yet, but I probably will... maybe after today's class!

Best answer will go to the person who either lists a site which is self-explanatory or lists a site with instructions for using the calculator. PLEASE include a description with your answer, not just a link.

Thanks!
