1. Problem Solving
Solving a problem for which you know theres an
answer is like climbing a mountain with a guide,
along a trail someone else has laid. In mathematics,
the truth is somewhere out there in a place no one
knows, beyond all the beate

Chemistry lesson #1
The number of protons in an atom = its atomic number.
The number of protons in an atom determines what element it is.
An atom of silver for example with 47 protons in its nucleus is ALWAYS an atom of silver
independent of what its elec

What will we do with radioactive waste?
Nuclear power plants produce about
one-fifth of the United States
electricity. They also produce tons of
highly radioactive1 waste that has
nowhere to go.
