If the earth were made of very hard steel and a sparrow would come once every 100 million years to just brush the earth with the tip of its tail once,eventually the earth would finish because of that friction,ie it would carry off some atoms,but infinity would not finish!just think about this

What effect will this have on the world, if any? What does it mean to you and what would you like to see happen?

I was wondering if someone could perhaps EXPLAIN how to solve this problem. =]
Assume that element Uus is synthesized and that it has the following isotopes:
284Uus (283.4 amu) 34.60%
285Uus (284.7 amu) 21.20%
288 Uus (287.8 amu) 44.20%
What is the value of the average atomic mass for Uus that would be listed on the periodic table? [please use significant figures]

I don't even know how to begin this problem. x] Thanks to anyone that can help. :]

I dont believe in god. Only science and I doubt that some imaginary power such as god created something that exist today.

This is a simple question but one I find puzzling.

Tiny molecules go through our blood, and capiliaries, and within the cells themselves.
How do they get guided to the right place?

For example, if a tiny mitochondria accepts and produces various proteins (which are extremely small, even on the cell level) How do they get guided to the right place?

I don't buy the argument that they bounce around inside a cell until they attach correctly to some other structure...its too unlikely....what is guiding these molecules to the right place?

Any creative insights would be greatly appreciated.
thanx!

Are there any microbiologists out there? I am really curious about a career in microbiology or molecular biology. Generally, what kinds of jobs are out there? What is the average salary for each field? Any information, experiences, or thoughts would be great. Thanks.

I have to find maximization of f(a)=20(a-1)^1/2-2a-20...and I don't have a clue how to do it. I tried to differentiate it but my answer is wrong.
