26. Some lions mate over 50 times a day.
Is that why they call it a "pride" of lions?
Can one believe a male ly-in' about his sex life?

I don't think so, Mav. I've heard that you have to pay for it  . Actually, I have read that in some of the "Swim with the Dolphins" programs, you must watch out because some of the dolphins have been known to, shall we say, misbehave?

Here's Dr. Duke's response to the ostrich factoid:
Yes, the brain is the size of a golf ball in adults. The eye is about the
size of an adult human eye and is the largest eye of any land mammal.

But is the human eyeball or slightly larger for the ostrich eye larger or small than a golfball? Hmmmmm, the search for facts continues...

Ahhhh, back to thermo.
Yes Keiva, you are almost exactly right. The density of water increases from 0-4 degrees C, or 32-39 degrees F then falls as the temperature rises.
At 0 degrees C water weighs 62.4199 #/ft3.
At 4 degrees C it is up to 62.4283 #/ft3.
At 100 degrees C water weighs only 59.8307 #/ft3.

re: cold water-- and this is why when water pipes break-- they leak! the pipes don't break because the water is frozen (in which case,you'd have an icy pug on the break) but because the water is cold, and at maximum density- and still all too liquid!

With all due respect troy (ye of veteren status to my measly newbie state), I believe that the contraction and constriction of the piping material has more to do with the breaking of water lines.
In addition, you may very well have ice in the lines prior to the break but it is the warming of the pipes (and consequently whatever is in them) that causes the break. That warming will likely be enough to have facilitated the change from ice to water at this point. The outside air (even underground) will likely be warmer too than the ice plug and thus the temperature change will quickly melt the ice and allow the pipes to 'leak'.

My ex-father in law was the one who told me that cold water (not ice) broke pipes-- but as you say-- it could be a combination of the pipes contracting in the cold as much as the cold water expanding.. since he had licences in both high pressure steam and refrigeration (engineering), i believed the story.
