GREAT MOMENTS IN ODORIFEROUS ACADEMIA
Here are the factors involved in calculating odor based setbacks (as
calculated by the Purdue Agricultural Air Quality Laboratory - your own
calculations may involve a different mix of factors):
F = wind frequency factor [0.75 to 1.00],
L = land use factor [0.5 to 1.00],
T = topography factor [0.8 to 1.00],
V = orientation and shape factor [1.00 to 1.15],
E = building odor emission, N x P x B, OU/s,
N = number of pigs,
P = odor emission factor, OU/s-pig, [1 to 15],
B = building design and management factor, M-D,
M = manure removal frequency [0.50 to 1.00],
D = manure dilution factor [0.00 to 0.20],
S = odor emission from outdoor storage, C x G, OU/s,
C = odor emission factor for outside liquid manure storage, 50 OU/s-AU
G = animal unit, AU=1,100 lb of pig weight.
AE = odor abatement factor for buildings [0.30 to 1.00],
AS = odor abatement factor for outside liquid manure storage [0.30
to1.00]

WOULD DARWIN HAVE FOUND EVOLUTION IF THERE HAD BEEN AN INTERNET?
MICHAEL WHITE, ADAPTIVE COMPLEXITY - How can today's wired, multitasking
scientists ever compete with the great scientists of the past? One
feature of Darwin's work as a scientist was that it proceeded slowly,
very, very slowly. He wrote massive groundbreaking books, compiled huge
amounts of data on orchids, barnacles, and Galapagos animals, but all
over a long period of time. Scientists in Darwin's day had hours to kill
on long voyages, took long walks out in the field, and waited while
their scientific correspondence leisurely wended its way across oceans
or continents.
Even in the first half of the 20th century, great scientists are famous
for what they accomplished on long walks, hiking trips, and train rides.
Niels Bohr would walk for hours around Copenhagen and come up with
groundbreaking ideas, while Werner Heisenberg spent weeks every year
hiking in the mountains. Even Richard Feynman, working in our more
modern (but still pre-internet) era, insisted on long blocks of time to
concentrate; he likened his thought process to building a house of
cards, easily toppled by distraction and difficult to put back together.
Does that mean the kind of science we do in our overscheduled,
multitasking world will never be the same as it was in the past?
Certainly in one sense it won't - earlier generations of scientists had
one distinct advantage we don't have today: servants.
But I don't want servants. . . I just want time free from the
instant-response expectations that fill our days. Blog posts have to be
quick and spontaneous, or else they are obsolete; if I don't look at the
dozens of new science papers published today, they will be buried under
two dozen more published tomorrow; if I don't check all those
interesting RSS feeds in my browser this morning, I'll be reading only
the response to a response to a post tonight; if I don't reply
immediately to the dozens of emails I get each day, then people will
think I'm disorganized, lazy, or just ignoring them. . .
I agree that more good science is being published than ever before. But
much of it also follows two trends: big-team science, solving big
problems by brute force; and detail-filling science, not especially
innovative, but usually useful. Where does this leave the kinds of deep
breakthroughs, that in the past have always arisen in the minds of very
focused individuals? . . .
Then again, maybe not all great scientists of the past needed great
periods of isolation to work. Einstein, perhaps the greatest 20th
century scientist, wrote four groundbreaking papers, all while having a
young kid at home and holding down a full-time day job at the patent
office. . . Maybe if Einstein had email, he would have written five
papers.
