I've always wanted to reach my dream of owning my own falcon...honstely I've got my heart set on a Gye - in other words a GyroFalcon.
Well, I'm told I can get a Falconeir's liscense form my state's "game and fish department" To get the liscence they say I'll have to take a test in Biology, training and vetinary, I'm a science wizz, read a wee bit on how to train, and can ask my school's vet-med class for help, so I think I'm good...but one article says i have to compete in the sport, make my bird hunt a minuimum of 3x's a week, now I'm pissed, I juts want a campaignen from my falcon, I'll train her to hunt, but gosh, I ain't gonna make my bird hunt for sport, is it true, without hunting, am I not allowed to own a bird?

Plus IF, by a long shoot, anyone knows someone who can help me get my hnads on a gye, I'd gladly aprreciate it, they live on the other side of the U.S. from me, I'm in Florida... thanks for your time

At high temperatures we see trees combust and turn to ash, but is it possible for the temperature to rise high enough that the bark and all the other parts of a tree would turn to liquid? If not, why not?

Since its already winter here, there are no leaves to use to help identify the trees, just some pictures I took of the bark.
I'm trying to determine if the following two trees are Maples:

Afterwards God gave Noah a sign that he would never do it again. A rainbow. Had there been rain before a rainbow would not have been so significant. Thought to ponder.- We know that water goes into the sky (up), without raining. (evaporation) We also see water drenched fields (dew), without it raining.

I want to contain, insulate, or shield a magetic field. Is there any kind of material that will do that?

I am building a large electromagnet with some metal rods and wire, but I only want to use the north end of the magnet for these particular experiments. Shielding the opposite field from reaching too far isn't completely nessesarry - it would just be far more convienient that way. I dont want to have to worry about the south end backlash and what affects it wold have on anything remotely nearby. (Computers, videotapes, laptops, certain cell phones, etc)

Curious about some answers to an earlier question. As I understand the big bang theory it produced all the mattter in the universe, but surely empty space infinite nothingness was here before the big bang, according the the theory?
I cannot agree that time began with the big bang, because change must have occured for the big bang to start.

What does it mean in Calculus when they say; find the derivative of this function using the definition. What is the definition? (I'm sure I have learned it but I can't remember what it is) A simple example would help a lot.
