Science & Mathematics - 6 December 2006

I am helping my son with homework. He is doing a "Change in Temperature rc" experiment and recording the changes by adding 1 then 2 then 3 spoonfuls of calcium chloride. I have been out of school for so long and don't use this practice in my line of work so feel pretty ignorant right now. This is only 7th grade work!

Help... This is a science project in PHYSICS and we have to find out how
could we not break the egg as we drop it from the 3rd floor. Our teacher said
that the materials we only have to use is 2 sheets of newspaper or any paper, a raw egg (as in a chicken egg) and scotchtape or a string. Then out of the paper, we have to make a parachute to be intact in the raw egg as we drop it from the 3rd floor. Could anyone answer how could we not break the egg... What would be the design of our PARACHUTE made from newspaper or any paper so that the egg would not break.... Thank you... Hoping for a quick response... :)

The probability a seed germinates is p and seeds germinate independently of each other. If n rows of m seeds are planted, find the probability there are 2 rows each containing 1 seed that fails to germinate, all other seeds germinating.
I got mp^3(n-2)(m-1)^2(1-p)^2.... do you think this is right?!

Okay, this may sound weird as hell, but here goes:

Whenever I think about the universe, and how BIG it really is (how there are billions of stars with their own planets and how there are probably millions of other alien species), I REALLY begin to doubt, well, basically... EVERYTHING.

Like, right now I'm sitting at my desk. I feel so insiginficant. The world around us is waaay too complicated. Everything feels like a huge hoax to me.

After I die, what happens? Will the universe still exist? Was this universe made for ME? Is there even such thing as 'space' ? I mean, no one you know has actually gone out to space.

What if everything around us is a huge hoax? (sort of like the movie "The Truman Show", but to a greater extent)
