A read of Stephen Hawking will probably bring
you as up to date as we can get and is actually
quite readable.

And that also brings this full circle. Hawking
is very asymmetrical at the moment, and was not
so at one point in time, so the thing in us that
I also believe is an evolutionary trait, the
physical desire for the more symmetrical, would
have you barking up the wrong tree in his
case...as his genes are quite good, I think.

But human beings are "naturally" inclined to
a lot of stupid things.

Ivor, the key word in my statement is "roughly." I'd like to see the
potter who could throw an exact hemisphere.
