A few of my favorites, not found in the linked article: "There are two ways of constructing software. One way is to make it so simple that there are obviously no deficiencies. The other is to make it so complex that there are no obvious deficiencies." C.A.R. Hoare "The purpose of software engineering is to control…
Civilisation, like life itself, has always been about capturing energy. That is to say, just as a successful species is one that converts the sun’s energy into offspring more rapidly than another species, so the same is true of a nation. Progressively, as the aeons passed, life as a whole has grown gradually more and…
And the answer is, ‘yes.’ I think there’s three main lessons we can learn: First, there’s no one correct diet, but diversity is the key. So, depending on where you live, you can eat very different things, but you need diversity. We lack the ability to synthesize many nutrients that we require for life, nutrients and…
THE FOLLOWING IS QUOTED FROM BERGAN EVANS ON NORBERT WEINER, NUCLEAR PHYSICIST The second concept Wiener has to establish is that of entropy. Probability is a mathematical concept, coming from statistics. Entropy comes from physics. It is the assertion-- established logically and experimentally-- that the universe, by…
...complex systems, such as financial markets or the Earth’s biosphere, do not seem to obey causality. For every event that occurs, there are a multitude of possible causes, and the extent to which each contributes to the event is not clear, not even after the fact! One might say that there is a web of causation. For…
Imagine that George, who is wearing a spacesuit with a small, red flashing light, is floating in the absolute darkness of completely empty space, far away from any planets, stars, or galaxies. From George's perspective, he is completely stationary, engulfed in the uniform, still blackness of the cosmos. Off in the…
Neutrinos were first predicted to exist as the result of a puzzle related to the decay of neutrons. While neutrons are stable inside atomic nuclei, free neutrons are observed to decay, in an average time of about 10 minutes, into protons and electrons. The electric charge works out fine, because a neutron is…
Many plants new to North America first sprouted up alongside wharves and shipyards. From there they made their way inland along new roads hacked out of the wilderness, and later along canals and railroad embankments, taking up residence in any sort of disturbed soil. Native plants adapted to quiet precolonial forests…
