The arctic fox is an incredibly hardy animal that can survive frigid Arctic temperatures as low as –58°F in the treeless lands where it makes its home. It has furry soles, short ears, and a short muzzle—all-important adaptations to the chilly clime. Arctic foxes live in burrows, and in a blizzard they may tunnel into the snow to create shelter.
The atmospere doesnt contain enough oxygen and the temperature is way to cold
Here's what he must do:
-- Run the experiment again, several times if possible. Combine or
analyze
the results of the several experimental runs in some statistically
valid way.
-- Run the simulation again, several times. Combine or analyze the results
of the several simulations in some statistically valid way.
-- Then, compare the analysis of several experimental runs with the analysis
of several simulations, in some statistically valid way, to decide whether they
<em>really</em> don't track.
-- If they do, then look for ways to tighten up the simulation so that maybe
they can track better.
-- If they don't, then he's back to <em>before</em> Square-1. He not only has to
deal with the question of whether or not his experiment is valid, but he
also has to consider the possibility that his simulation is trash and
doesn't actually model nature like he expected it to.
