I got this amazing newbie book a few days ago. Why didn't anyone
recommend it nor is it in Baez reading list? It's even better
than other newbie GR books like Geroch's "General Relativity
from A to B" or Clifford's "Was Einstein Right?" I own both too.
And the most amazing is that Wheeler's "A Journey into
Gravity and Spacetime only costs around $2. That is. The
1999 soft edition selling for $54 has the same contents as the
1990 hardbound edition. The latter is only being sold for
as low as $2 (where I got mine) and there are half a dozen
selling for around $3 in amazon marketplace section. The
book is in full color. Amazing!
Anyway. I have a question about a topic in the book. It
concerns "boundary of a boundary".. I wonder what official
name is it called in differential geometry or GR Proper. The
descriptions of it is herein described by one of the
reviewers at amazon:
"Most difficult for a layman to understand is how spacetime
acts on masive objects, but the author explains it brilliantly
in the next chapter, taught via the concept of "momenergy".
This entity is a 4...

Who else (of reliable source) has good list of layman books for SR,
GR, QM, etc.? I thought it's only Baez who has them. I think
he reads hundreds of books and know which is junk and good
for us who can't afford that much money.
