Solve by the square root property. Complete the square first, if necessary.

-4z = 3 - z^2

Hi,

We say matter is something that has mass.
So, can we say lepton, quark, W and Z boson etc. are matters because they have mass?
If mass is the quantity of matter that a body contains, then these particles are matter.

Scientists also say fermions are the littlest units of a matter.
W and Z bosons also have mass but fermions are not their littlest units.

How can we describe mass and matter in modern science?

PLEASE DO NOT ANSWER WITH LINKS.

Thanks a lot.

What a load of garbage! I don't believe that for one second. Why is it, despite the massive amount of information out there, ppl still believe this? http://www.snopes.com/critters/wild/longlegs.asp
Do ppl want to believe this and then therefore refuse to look at the facts? Or are ppl really that closed minded that they believe the first thing they hear/read and stick with it for their entire lives?

The heated material has more energy than before, so does it weigth more?
I know the gain would be very very very small, but does this happen? m=E/c2
