ABOUT 13.5 BILLION YEARS AGO, MATTER, energy, time and space came into being in what is known as the Big Bang. The story of these fundamental features of our universe is called physics. About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then…
In summary, the circumstellar shells of Dyson civilizations-at temperatures ~300 degrees K and radii ~1 a.u.--can be detected with existing telescopes and state-of-the-art infrared detectors in the 8-13-u window out to distances of several hundred parsecs. But discrimination of Dyson civilizations from naturally…
The teaching that there is no objective reality, but rather many subjec¬ tive realities, or in this case, that the subjective realities are on an equal par with the objective reality (you're dead!) in turn influences students' views of the primacy of knowledge. To critics, history is no longer the search for what…
Just now nuclear physicists are writing a great deal about hypothetical particles called neutrinos supposed to account for certain peculiar facts observed in ß-ray disintegration. We can perhaps best describe the neutrinos as little bits of spin-energy that have got detached. I am not much impressed by the neutrino…
In a very real sense human beings are machines constructed by the nucleic acids to arrange for the efficient replication of more nucleic acids. In a sense our strongest urges, noblest enterprises, most compelling necessities, and apparent free wills are all an expression of the information coded in the genetic…
A weed plucked at the side of the path might have found its way to the New World in a seventeenth century sailing ship. Scratches on a rocky ledge evoke colossal mountain-building events on the other side of the world millions of years ago that modified the planet's climate and caused glaciers to creep across New…
In his celebrated little book, On Liberty, the English philosopher John Stuart Mill argued that silencing an opinion is 'a peculiar evil'. If the opinion is right, we are robbed of the 'opportunity of exchanging error for truth'; and if it's wrong, we are deprived of a deeper understanding of the truth in 'its…
[Schopenhauer] was also an atheist. He did not believe in a personal, omnipotent God. Instead, Schopenhauer believed that the essence of the universe is Being: a blind, irrational, unquenchable thirst to exist he called Wille zum Leben, and that everything we perceive is a representation of this Will to Live. Because…
From the early days of Darwinism analogies have been drawn between biological evolution and the evolution of culture. Darwin's contemporary Herbert Spencer studied the evolution of civilizations, which he viewed as progressing towards an ideal something like that of Victorian English society. Lewis Morgan's…
