Since we're at the top of the food chain and that we have a pretty stable enviroment, do you think that there will be anymore changes to ourselves? What if something comes along and starts threatening the lives of those who are weaker?

Who makes the "laws" of nature/science?

(please don't say God.)
Can we bring back Isaac Newton (or someone as good, I'm not picky)from the dead and have him write up a couple of new laws, and put an end to this whole "evolution is just a theory, so it can't be true" nonsense?

I need advice please. Inventive & intelligent. Interested in physics, robotics & more. What to do?

School irritated the cr*p out of me. But I was always told I was quite intellligent, and had excellent spatial abilities. I'm 27 now. I have done many odd jobs over the years. I work on cars and build stuff a lot and do carpentry and sculpting. I'm also a musician and juggle. -but science nags at my brain. when my coworkers are gabbing about some utter drivel they watched on TV last night, I'm thinking about DARPA's next competition or how beautiful water looks in microgravity... and I have a little book of inventions I write ideas down in a lot.

I just wish there was some way I could get into something that's more on my level and stop working these crap jobs... my friends joke about me being like that damned "Good Will Hunting" movie -that's another thing. - I'm not even that good at math. I almost stopped going to high school. dropped out of college.

Anyone know what would be a good start for someone with low math skills who is creative with very high mechanical ability?

What type of spider has an amber or light orange or light brown hourglass on the belly?

I'm thinking its some type of mutated black widow but it had some funky looking designes on its back that I can't describe. It was about 1 inch in lenth and all black except the markings i mentioned. I can't describe the markings on the back because I can't remember the details. The damn thing is long dead now but I sure hope there are no babies. I had my apartment spray for spiders, however, I live in southern Nevada. Any knowledge of such a spider?

Solve for the value of all 5 variables?

At least one solution

4x²y - 3x(z - 2x)² = 4x³y³(2x + 2yz)
vw²(v - 7xz) = 4x(x + 2v²yz)³
x + 22y = 4v - yz
vx = (v - x³)² - 5xz³(5v²w³x³ - 2x³)²
x³ - y³ - 13z³ = (2vw + 3xyz)³

This is easy---- trust me!

^_^

b.HF(aq+HCL(g)---------> F(negative) (aq) +NH4+(aq)
c.H2O(l) =HCl(g) ----------> H3O+(aq) +Cl-(aq)
d.Al2O3 +2NaOH(aq) + 3H2O(l) ---------->2NaAl(OH)4 (aq)
e. Cu2+ (aq) +4NH3(aq) -----------> [Cu(NH3)4]2+(aq)

The right side of my upper lip keeps twitching...could it be some kind of vitamin deficiency?

It's not constant. It feels like a pulsation.
