I live in the freezing bowels of Canada. When I go on vacation to a somewhat warmer climate, where the temperatures are around 5 to 10 degrees Celsius (40 to 50 degrees F), I find it warm and walk around in a t shirt and shorts while people look at me like I'm crazy. Is my body physically used to the cold or is my mind just fooling me? In other words, am I convincing myself that I should feel warmer than these wimps and so I do?

I know you can eat raw fructose and sucralose. In their raw forms, are glucose and sucrose edible, or do they require processing?

So the thing goes that you can warp through time at high speeds of under extreme gravity because the effect on space (who what). My question is that.........how did it get calculated that time and space are connected? How can you go through any speed equation and find that it takes a different ammount of time to go through than you used to calculate the speed?

Time dilation is the phenomenon whereby an observer finds that another's clock which is physically identical to their own is ticking at a slower rate as measured by their own clock. (wikipedia).

Essentially, a clock on the surface of the earth will go slightly slower than a clock on the moon where there is less gravity.

What I don't understand is how a black hole can collapse to an almost infinitely small mass when the time dilation would become increasingly high. I mean wouldn't time go so slow that matter falling in would completely stop?? Would an object falling in ever find the center before the end of the universe?

im stuck on a few problems, and im not sure how to do it.

Find the exact value of these, no decimal form.
cot(225)
csc(-7pi/4)
(csc42)(sec48)-(tan48)(cot42)
sec(-2pi)

please help out
I have one of them done, cos225 = -sqroot2/2

Thanks

My AP Physics class and I watched a three-part mini-series over string theory over the past few days and I was wondering what other people thought about it.
