Norman Borlaug, Giga-Lifesaver
In the 1950s and ’60s, another giga-lifesaver, Norman Borlaug, outsmarted evolution to foment the Green Revolution in the developing world.21 Plants in nature invest a lot of energy and nutrients in woody stalks that raise their leaves and blossoms above the shade of neighboring weeds and of each other. Like fans at a rock concert, everyone stands up, but no one gets a better view. That’s the way evolution works: it myopically selects for individual advantage, not the greater good of the ... 1

Tyrrany Sets Up Its Own Echo Chamber
I think it was Utz who first convinced me that history
is always our guide for the future, and always full of
capricious surprises. The future itself is a dead land
because it does not yet exist. When a Czech writer
wishes to comment on the plight of his country, one
way open to him is to use the fifteenth-century Hussite
Rebellion as a metaphor. I found in Prague Museum
this text describing the Hussites' defeat of the German
Knights: ''At midnight, all of a sudden, frightened
shouting was he...Folksonomies: tyrrany

Biocides
These sprays, dusts, and aerosols are now applied almost universally to farms, gardens, forests, and homes—non-selective chemicals that have the power to kill every insect, the "good" and the "bad," to still the song of birds and the leaping of fish in the streams, to coat the leaves with a deadly film, and to linger on in the soil—all this though the intended target may be only a few weeds or insects. Can anyone believe it is possible to lay down such a barrage of poisons on the surface ...Folksonomies: environmentalism

We Should Think of Ourselves as Atoms
we should consider ourselves but as atoms of organized matter, whose pleasure or whose pain, whose existence in a state of organization, or whose non-existence in that state, is a matter of no importance in the laws and operations of Nature; we should view ourselves with the same feelings, as we view the leaf which rises in the spring, and falls in the autumn, and then serves no further purpose but to fertilize the earth for a fresh production; we should view ourselves but as the blossoms of ... 1 notes

Fire is Unwinding the Sun's Energy from the Trees
Nobody is bom a specialist. Every child is born with comprehensive interests, asking the most comprehensively logical and relevant questions. Pointing to the logs burning in the fireplace, one child asked me, "What is fire?" I answered, "Fire is the Sun unwinding from the tree's log. The Earth revolves and the trees revolve as the radiation from the Sun's flame reaches the revolving planet Earth. By photosynthesis the green buds and leaves of the tree convert that Sun radiation into hydrocarb...

1 Every year the trees store the sun's energy in a ring. When we burn the tree, we are unwrapping that energy.

Experiment Demonstrating Plants Produce Breathable Air
When air has been freshly and strongly tainted with putrefaction, so as to smell through the water, sprigs of mint have presently died, upon being put into it, their leaves turning black; but if they do not die presently, they thrive in a most surprizing manner. In no other circumstances have I ever seen vegetation so vigorous as in this kind of air, which is immediately fatal to animal life. Though these plants have been crouded in jars filled with this air, every leaf has been full of life;...Folksonomies: experimentation

How File Structure Affects Our Perception of the World
The file is a set of philosophical ideas made into eternal flesh. The ideas expressed by the file include the notion that human expression comes in severable chunks that can be organized as leaves on an abstract tree—and that the chunks have versions and need to be matched to compatible applications. 1 notes
notesFiles are compact chunks that can be categorized, have versions, and can be matched to applications. But don't we do this with taxonomy in biology? Species are defined, but they are flowing degrees of characteristics that we semi-artificially categorize.

Fractal Geometry Changes One's Perspective of the World
Fractal geometry will make you see everything differently. There is a danger in reading further. You risk the loss of your childhood vision of clouds, forests, flowers, galaxies, leaves, feathers, rocks, mountains, torrents of water, carpet, bricks, and much else besides. Never again will your interpretation of these things be quite the same. Folksonomies: perspective fractals

Convergent Evolution in Cacti and Succulents
Let’s begin with one observation that strikes anyone who travels widely.
If you go to two distant areas that have similar climate and terrain,
you find different types of life. Take deserts. Many desert plants are
succulents: they show an adaptive combination of traits that include
large fleshy stems to store water, spines to deter predators, and small or
missing leaves to reduce water loss. But different deserts have different
types of succulents. In North and South America, the succulents... 1 notes
notesThe two groups of species share many many traits, but they exist in completely different parts of the world, evolving separately, but converging to be almost interchangeable.

The Foundation of Science, Not the Periphery, Is Where th...
A number of years ago, when I was a freshly-appointed instructor, I met, for the first time, a certain eminent historian of science. At the time I could only regard him with tolerant condescension.
I was sorry of the man who, it seemed to me, was forced to hover about the edges of science. He was compelled to shiver endlessly in the outskirts, getting only feeble warmth from the distant sun of science- in-progress; while I, just beginning my research, was bathed in the heady liquid heat up a... 1 notes
