“The macromolecules of organic life embody information in an intricate structure. A single hemoglobin molecule comprises four chains of polypeptides, two with 141 amino acids and two with 146, in strict linear sequence, bonded and folded together. Atoms of hydrogen, oxygen, carbon, and iron could mingle randomly for the lifetime of the universe and be no more likely to form hemoglobin than the proverbial chimpanzees to type the works of Shakespeare. Their genesis requires energy; they are built up from simpler, less patterned parts, and the law of entropy applies. For earthly life, the energy comes as photons from the sun. The information comes via evolution.”

“Every day in the human body, some 10 billion cells die and are replaced by new cells. The cells that die do not meet a violent unpremeditated end, but are removed silently and unnoticed by apoptosis, all evidence of their demise eaten by neighbouring cells. This means that apoptosis balances cell division”

“A wealth of research confirms the importance of face-to-face contact. One experiment performed by two researchers at the University of Michigan challenged groups of six students to play a game in which everyone could earn money by cooperating. One set of groups met for ten minutes face-to-face to discuss strategy before playing. Another set of groups had thirty minutes for electronic interaction. The groups that met in person cooperated well and earned more money. The groups that had only connected electronically fell apart, as members put their personal gains ahead of the group’s needs. This finding resonates well with many other experiments, which have shown that face-to-face contact leads to more trust, generosity, and cooperation than any other sort of interaction.
The very first experiment in social psychology was conducted by a University of Indiana psychologist who was also an avid bicyclist. He noted that “racing men” believe that “the value of a pace,” or competitor, shaves twenty to thirty seconds off the time of a mile. To rigorously test the value of human proximity, he got forty children to compete at spinning fishing reels to pull a cable. In all cases, the kids were supposed to go as fast as they could, but most of them, especially the slower ones, were much quicker when they were paired with another child. Modern statistical evidence finds that young professionals today work longer hours if they live in a metropolitan area with plenty of competitors in their own occupational niche.
Supermarket checkouts provide a particularly striking example of the power of proximity. As anyone who has been to a grocery store knows, checkout clerks differ wildly in their speed and competence. In one major chain, clerks with differing abilities are more or less randomly shuffled across shifts, which enabled two economists to look at the impact of productive peers. It turns out that the productivity of average clerks rises substantially when there is a star clerk working on their shift, and those same average clerks get worse when their shift is filled with below-average clerks.
Statistical evidence also suggests that electronic interactions and face-to-face interactions support one another; in the language of economics, they’re complements rather than substitutes. Telephone calls are disproportionately made among people who are geographically close, presumably because face-to-face relationships increase the demand for talking over the phone. And when countries become more urban, they engage in more electronic communications.”

“An exploding nuclear bomb has a much higher power density than the sun because it is an unsustainable out-of-control flow of energy. A one-megaton nuclear bomb will release 1017 ergs, which is a lot of power. But the total lifetime of that explosion is only a hyperblink of 10-6 seconds. So if you “amortized” a nuclear blast so that it spent its energy over a full second instead of microseconds, its power density would be reduced to only 1011 ergs per second per gram, which is about the intensity of a laptop computer chip. Energywise, a Pentium chip may be better thought of as a very slow nuclear explosion.”
