mereotopological - Did you invent this word? What does it supposed to mean?

I agree with Fermi. Interstellar distances are a the main problem.

Define numbers. As is the question doesn't make sense.

Science fiction is your best bet.

Most of physics and much engineering needs calculus. I suggest you learn a little bit about the subjects you are asking about.

Second law is statistical.. It is possible for something weird to happen, but the probability is astronomically small.

The statement is a little confusing. I believe its intent was to consider only those values of X which have a probability greater than zero. Simple example: X has 3 values 0,1,-1. f(-1)=1/4, f(0)=1/2, and f(1)= 1/4. g(-1)=0, g(0)=1, g(1)=2. Then E(g(X))=1.

I suspect food production will continue.

This is not completely true. There are matriarchal societies (in Papua among other places) today.

Instructions should include how to bracket statements. math and /math inside [] works. Does anything else?

Get Brady to age faster.

To answer the original question \(r,\theta,\phi\) are scalars, while \(\vec r\) is a vector whose coordinates may be the spherical coordinate scalars or more often (x,y,z).

If you believe in god, then things must have a purpose. Otherwise things are the way they are due to the laws of physics.

He3 is an intermediate in the H1 to He4 transformation, so the % should be minimal.
