Visualising energy




human body = one gallon per 8 lbs
12 gallons per 100#
60% water = 7 gallons water per 100#
16% fat = 2 gallons fat per 100# (16#, 7kg)
22% protein = 2.6 gallons protein per 100# (22#, 10kg)

3.8*10^4 joule = energy in gram of fat
2.7*10^8 joule in 7kg

1.7*10^4 joule in gram of protein
1.7*10^8 joule in 10kg

4.4*10^8 joule in 100# body

4.186*10^3 joule = 1 Calorie
1 kiloCalorie per pound in human body

3.6*10^6 joule = kilowatt-hour
100 kW-hr per 100# body
half a microgram of antimatter [cite]

1.5*10^10 joules in a ton of wood [cite]
40 100# humans

10 tons per tree?
400 humans

1.74*10^17 joule = solar energy worldwide per second
400 million 100# humans per second
10 million tons of wood
1 million trees

10^36 photons/second [cite]

10^14 joule = solar energy trapped by photosynthesis per second [cite]
(10^33 photons or 0.1% cite)
20 million 100# humans per second

4*10^26 joule = energy generated by fusion in Sun per second [cite]
10^20 kW-hr (100 quintillion)
8*10^19 100# humans per second?

ToE vs ToL

edward o wilson's
elegant autobiography
"Naturalist"

sketches an epochal
Shem/Shaun brotherbattle
in Harvard's biology department
of the 50s and 60s
between wilson
representing the classical tradition
of evolutionary macrobiology

and james 'double helix' watson
as the insufferable young turk
of molecular biology
dismissing wilson's classical tradition

until the introduction of mathematical models
for sociobiology
and island biogeography
rehabilitated that tradition




and i see a parallel
with the classical approach to the
unification of the sciences

versus the physicists' megalomaniacal
ten-dimensional Theories of Everything

rehabilitatable via
the Tree of Life
approach?
