I need to make a graph on excel, frequency V velocity. But when i try to the graph comes out blank. I tried using the scale thing but i dont understand it, and when i try doing it it comes out as 2E+17 .... Frequency has 10 numbers between 20,000-200,000,000,000,000,000 and the other is velocity which has 10 numbers that are all 300,000,000

i've been searching on the internet, wasting hours of my time. i am hoping to find an image, list of properties, and a place where i can buy a small amount without being totally ripped off as i know of one place that wants to sell many pounds at a time...all i want is a piece 1/4" by 1" by 2". the alloy i dont think is exotic at all, is 70% copper, 30% zirconium (not zinc). I am willing to pay $5 for a 2 ounce piece (that's $60/pound, which i think is a not bad to a supplier as it's just $6/pound in bulk anyway).

please help! as far as other alloys go, perhaps you can tell me a general link where i can find images of alloys of my choosing? yahoo images is not so robust in doing it.

thanks in advance!!!

Since the building blocks of life can appear at random throughout the universe can this also happen to other substances (a planet with a chocolate sea perhaps).

this means patents, literature(text), art, music, software, code, et cetera. By no longer private, I mean people sell them, but they are no longer limited by having to buy them or following terms of use.

I was reading a little bit about atoms today, and I didn't really get the whole thing about quarks. What's a quark? What does it do in/or for atoms? How does that help us?

Australia has been de-salinating seawater for years.
It is 70% of their water consumption.
Why can't Australia do this? You have an unlimited supply.
There is no shortage of water in Australia, just a shortage of de-salination plants.

I did a science fair project involving placing butterfly larvae in different rooms with different temperatures to see which ones developed faster. My hypothesis, which was proven, basically stated that the larvae in the warm room would grow faster than all the other groups. Now i have to make a null hypothesis....Would exactly would that say? Like...there will be no difference or something? Thanks...

Rupert Sheldrake, a well known and prestigious scientist (check out wikipedia) did a double-blind in which people were asked whether or not they were being stared at from behind. Apparently the results were 60% true - well above the 50% associated with chance. Does anyone know if this has been addressed by the scientific community?

Thanks!
