Archived from groups: alt>books>david-weber (more info?)

Weber has people adapted for life on high-gravity worlds being substantially
larger than us lesser mortals, the higher the G field, the larger the
specimen. I'm not sure that makes sense. Muscle strength scales as the
cross-sectional area of a particular muscle while mass scales a cube
function of stature. It seems to me that heavy worlders should be _small_
not large. A straight scaling downward of the human form would decrease mass
loading faster than muscle strength drops and in the opposite direction, a
scaled up human with standard muscle fibers would be crippled by added
weight as the scaling increases. Of course, you can McGuffin-ize the muscle
fibers to be Better Than Human but then, why scale them up in size?

The hydraulics of circulation add to the problems of tall people in high G
fields, with long columns of blood exacerbating water hammer effects at the
extremities, including the brain.

Paul, I do believe you have something here. Short and squat seems
logical.

Now I can't help picturing her with an ax instead of a gun in the
replacement arm. And a beard.

A switchblade ax in her forearm?

That'd be more of a gnome thing.

Gnome? Feet, ankles, knees and hip joints, spines; all would require
some natural evolution to bear up under the stresses of every day
living. For instance, our pro athletes who after retirement creak
about, their bodies beat down by the abnormal stresses experienced
during their playing career. Bodies will adapt and evolve to meet the
environment. Viz: Inuit in the cold (stockiness) and Chileans (chest
capacity, more hemoglobin) in the Andes, pygmies in the deep jungle
(dearth of food) , and those wee people on Flores Island (probably
food) so recently in the news. 1.3 G doesn't sound like much but that
would load up a 150 pounder with 45 more pounds 100% of the time.
Creak, snap crackle pop..

The pygmies are sized by thermal management requirements. The equatorial
triple canopy jungle doesn't get real hot but the humidity is always 100%.
The pygmies maximize surface to volume ratio by the same square-cube law.

I thought he answered all that when he described the increased musculature and
heavier skeletal structure. These mods keep the gnome thing from happening.

Makes me wonder about Hemphill's ancestry.

Who for Kendar and Gully Dwarves?

Nah; whatever else you say about her, she isn't _stupid_. So I doubt
Gully Dwarves.

More likely tinker Gnome, with a maybe a dash of Valenar for that "Full
speed ahead, and damn the common sense!" methodology.

My favorite type reading. Too bad the rest of that Universe is so blood
soaked.

Not neccessarily. The body adapts to the added stress very quickly. All
you have to do is look at the US Army. You take a 160lb soldier. Once you
add body armor, weapons, ammunition, and the other gear needed you easily
increase his weight by over 30 percent. Yet these soldiers are able to
run, jump and fight. It does take training to build them up for it. A
person born and raised on a "heavy" world would be trained by the natural
environment. Put that person in a "standard g" environment and he would
seem to be a "superman". Examples of this adaptation are evident in the
long distance runners from Kenya. They train in the thin air of the Kenyan
Mountains. When they race in the denser air of lower altitudes their
bodies adaptation to the thin air provides them with a marked advantage
over "sea level" trained runners.

Even a soldier isn't loaded down with that extra weight 24 hours a day,
7 days a week, 365 days a year.

And how many 40 year olds are doing this?
