Once helium burning has occurred... the next possible reaction-carbon burning-is not necessarily slow... This reaction involves ...a strong as opposed to a weak interaction. ...Carbon burning results in magnesium. ...Taking a cross section of a highly evolved star would reveal a system of many layers. The inner layers have been subjected to the largest pressures, thereby forced to the highest temperatures, and burned the furthest; the outermost layers, by contrast, have not burned at all. Thus, as we proceed from outside in, there will be an outermost layer with the initial mix of hydrogen and helium, a layer of mostly helium, a layer of carbon, a layer of magnesium, and so on. ...So we arrive at the picture of a star, in the latest stages of its evolution... now composed of mostly carbon nuclei and other explosive material.
Frank Wilczek
Egoism and altruism are ideas we have about human nature. Historically, one has tended to arise in response to the other. In the ancient world, for example, it is generally in the times and places that one sees the emergence of money and markets that one also sees the rise of world religions-Buddhism, Christianity, and Islam. If one sets aside a space and says, "Here you shall think only about acquiring material things for yourself," then it is hardly surprising that before long someone else will set aside a countervailing space and declare, in effect: "Yes, but here we must contemplate the fact that the self, and material things, are ultimately unimportant."
David Graeber
With what moral authority can they speak of human rights - the rulers of a nation in which the millionaire and beggar coexist; the Indian is exterminated; the black man is discriminated against; the woman is prostituted; and the great masses of Chicanos, Puerto Ricans, and Latin Americans are scorned, exploited, and humiliated? How can they do this - the bosses of an empire where the mafia, gambling, and child prostitution are imposed; where the CIA organizes plans of global subversion and espionage, and the Pentagon creates neutron bombs capable of preserving material assets and wiping out human beings; an empire that supports reaction and counter-revolution all over the world; that protects and promotes the exploitation by monopolies of the wealth and the human resources of whole continents, unequal exchange, a protectionist policy, an incredible waste of natural resources, and a system of hunger for the world?
