Apologies in advance for the tangental topics below.

Another good example of this is Michael McCollum's _Antares_ series,
which includes ships with rings surrounding a cylindrical core. The ships
rotate when not accelerating or engaging in hangar bay ops.

I recommend McCollum's books, with one caveat -- if you haven't read
either
_Mote_ nor the _Antares_ books, read the _Antares_ books *first*.  The
technology is fundamentally similar in both (except McCollum doesn't have
force fields), and while MM does a better job of describing what the ships
look like, the mechanics of the jump drive, etc., JEP and LN are better
prosesmiths. This should not be interpreted as a criticism of Mr.
McCollum --
I am a _really_ big fan of his work, and own all of his novels.  (I may
own
all of JEP's, as well -- he's more prolific, so there's more to keep
track of.) See my sig below for info on McCollum.

2) Has anyone attempted a gaming campaign based on either the _Mote_ or
_Antares_ backgrounds?  I would expect that Pournelle's end of the First

Empire period (Sauron War) would provide some exciting campaigns, as would the
battle between the _MacArthur_ and the New Chicago cruiser in _Reflex_.

3) There was a long thread about rotating ships/sections on the _2300ad_

mailing list. One of the members, a former naval aviator turned physics PhD
candidate, points out that for ship-size objects, there are some nasty
side effects of spin. Basically, if your head is oriented in a particular
direction, it feels like gravity, but if you turn your head sideways, the
coriolis effect does all sorts of nasty things to your inner ear.

4) As an alternative to spin, Marshall Savage argues in his _The
Millennial
Project: Colonizing the Galaxy in 8 Easy Steps_ (1992) that the latest
research indicates that special skin-tight garments and
electro-stimulation of
muscle groups (while sleeping) would provide the necessary tension and
exercise to prevent loss of bone mass and muscle tone. He also postulates
spacesuits of the skin-tight semi-permeable design used by JEP and LN in

_Mote_, with tungsten armor over the top of them for radiation
shielding.

I enjoyed the first thirty pages of this book so much that I called up the
First Millenial Foundation and ordered a second copy in hardcover. I'm not
sure I buy all of Mr.Savage's calculations, but the man sure has vision, and
the book is definitely worth the $25 (hardcover) price tag.

5) Has anyone else:

(a) seen the disappointing _Guide to Larry Niven's Ringworld_?;

(s) concluded that the publisher should have simply acquired the rights to the
_Ringworld_ rpg, stripped out the game-related stuff, and published it
as the
_Guide_ instead?; and

(d) thought that a _Guide to Jerry Pournelle's CoDominium_ (complete
with lots of blueprints and tech data) would be something they would purchase?

I suggested the latter to JEP once; he responded that he didn't think there
was any market for it. <sigh>

Well, enough tangents for one day.

Yes it is VERY interesting! 8) Lots of info to build an imaginary future
around.

My freind picked his copy up at an "overuns/discontinued" bookstore for
only $4....It does pay to keep your eyes open!
