Because of the possibility of influencing the past while time traveling, one way of explaining why history does not change is by saying that whatever has happened was meant to happen. A time traveler attempting to alter the past in this model, intentionally or not, would only be fulfilling his role in creating…
As we look at planet Earth and the factors that enabled us to be here, we quickly realize that our planet is very special. Here’s a short list: the long-term existence of a protective and oxygen-rich atmosphere; Earth’s axial tilt, stabilized by a single large moon; the ozone layer and the magnetic field, which…
The Pareto distribution shows up in a remarkably wide array of complex systems. Together, “the” and “of” account for 10 percent of all words used in English. The most volatile day in the history of a stock market will typically be twice as volatile as that of the second-most volatile and ten times the tenth-most. Tag…
Anomaly (2) was observed by Fred Griffith, decades before DNA and the genetic code. He found that if you inject a heat-treated, dead, virulent species of bacteria (pneumococcus S) into a rat previously infected with a nonvirulent species (pneumococcus R), then species R became transformed into species S, thereby…
[Kurt D.] Squire has studied middle school kids who played Civ3. He found that some students who were able to spend the hours needed to learn the game began to identify “rules” by which history progressed; rules that apply to such issues as resource allocation, the tradeoff between aggressive military expansion and…
Thus it is that (to ensure feeding and breeding), "Nature" during the aeons of experimentation which we call "Evolution" has developed a variety of fixed preservative instincts, traits, and characteristics in the animal world. From the animal world, we as animals have inherited such of these instincts, traits, and…
Alexander had already devoted considerable sums to finance the enquiries of Aristotle, but Ptolemy I was the first person to make a permanent endowment of science. He set up a foundation in Alexandria which was formerly dedicated to the Muses, the Museum {151}of Alexandria. For two or three generations the scientific…
As everyone knows, the Chinese do not have letters, as we do, but symbols for whole words. This has, of course, many inconveniences: it means that, in learning to write, there are an immense number of different signs to be learnt, not only 26 as with us; that there is no such thing as alphabetical order, so that…
AND now let us indulge in a very interesting speculation; how did it feel to be a man in those early days of the human adventure? How did men think and what did they think in those remote days of hunting and wandering four hundred centuries ago before seed time and harvest began. Those were days long before the…
My professors’ generation could respond to silliness like creationism with head-scratching bemusement. My students cannot afford that luxury. Instead they must become fierce champions of science in the marketplace of ideas. During my undergraduate studies I was shocked at the low opinion some of my professors had of…
下 can be used to refer to the future, for example 下周 (below week) means "next week". It is as though the past is seen as being above us and the future below.
Death, to the Zhodani, is not a complete ending. The "evil" (that is, failure of duty) of the individual spirit will be lost. The "good" of the spirit will merge for a time with the universal energy field, the Tavrian, and then return to another member of the race. The more dutiful the spirit, the more personality…
The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them…
The active pursuit of uplift really took hold as a scientific field during the great flowering of transhuman culture, an era that also gave us the widespread settlement of space, extensive human genetic modification, nanotech, cognitive science, and the digital emulation of consciousness. It is in fact the convergence…
With digital archiving in all its forms, however, a new regime of technologies for holding past experience has emerged. Our past has always been malleable, but now it is malleable with a new viscosity. Whereas in the past our experiences were frequently (literally!) pigeonholed into rigid classification systems…
Taken globally, the set of traces that we leave in the world does without doubt add up to something. It is through operations on sets of traces that I understand an event that I take part in. Tolstoy wrote about the foot soldier in the Napoleonic wars. The soldier he describes cannot have the experience of the war he…
My interest is in the psychological adaptations that are uniquely human, the 10 percent or so of the brain's capacities that are not shared with other apes. This is where we find puzzling abilities like creative intelligence and complex language that show these great individual differences, these ridiculously high…
An effective strategy of predator satiation involves two adaptations. First, the synchrony of emergence or reproductions must be very precise, thus assuring that hte market is truly flooded, and only for a short time. Secondly, this flooding cannot occur very often, lest predators simply adjust their own life cycle to…
The researchers developed a software engine, called Entropica, and gave it models of a number of situations in which it could demonstrate behaviors that greatly resemble intelligence. They patterned many of these exercises after classic animal intelligence tests. [...] "It actually self-determines what its own…
The progress of the sciences secures the progress of the art of instruction, which again accelerates in its turn that of the sciences; and this reciprocal influence, the action of which is incessantly increased, must be ranked in the number of the most prolific and powerful causes of the improvement of the human race…
