And if there is no edge, how can that be?! This is driving me nuts, everytime i think about this, my brain starts to hurt.

How can there be an EDGE to the universe, and what is beyond that EDGE. If there is no EDGE, then what the heck!? How can one "thing" expand forever into nothing? Also, how do we know there is no edge? I guess we don't, this is just a theory, but how do people honestly try and back up such a bizarre theory that SOMEthing goes on forever. Surely then it isn't something, but nothing?

As you can see, i'm quite confused. Any help will really help!

Cheerio!

Sometimes when I use my pots and pans, there are circular rainbow patterns in them. When I add water, the rainbow colors go away. What's going on?

There are Vitamins A through K. But why do they leave out naming any of them with the letters, F,G,H,I, and J? Just A through E, then K.

Dr. Andrew Rowan a few decades ago wrote a history of the search for nonanimal research methods in the natural, medical, and social sciences, _Of Mice, Models, and Men_. The literature and organizations have proliferated, but largely the work is done in the area of animal welfare, not animal rights.

"Bad faith" abounds, I would argue, when we are not aggressively seeking to replace the use of animals and animal models in all areas of inquiry (basic research) and testing (as in all areas of feeding, clothing, entertainment, etc.).

Welfarism may have a time, but the moral obligations of accepting such a "welfarist" position are very great!

Equations:

Lc + Lf = 600 and Lc/Lf = 0.05
Tc + Tf = 60 and Tc/Tf = 0.20

(where Lc, for example, is the same as X...just a single variable...not L times c)

After I tried solving them, I got the answers of

Lc= 28.57
Lf = 571.42
Tf = 10
Tc = 50

However, my prof told me that his figures for X and Y were even, and that all my numbers were wrong. Can anyone shed some light on where I'm going wrong?

This is part of the Rybczynski Box Diagram I'm doing for my economics class. You can see the graph here if it helps:

>> http://www.plu.edu/~331f05/theory/rybczynski-box.html

Starting from the top (and going clockwise), the intercepts on the graph (with the axies) are Lf, Tf, Lc and Tc.
