The most singular, as well as the most excellent, of all his works, is that which is now the least read, and which is at the same time the most useful; I mean his "Novum Scientiarum Organum." This is the scaffold by means of which the edifice of the new philosophy has been reared; so that when the building was…
RULE I We are to admit no more causes of natural things, than such as are both true and sufficient to explain their appearances. To this purpose the philosophers say, that Nature does nothing in vain, and more is in vain, when less will serve; for Nature is pleased with simplicity, and affects not the pomp of…
When Benjamin Franklin invented the lightning-rod, the clergy, both in England and America, with the enthusiastic support of George III, condemned it as an impious attempt to defeat the will of God. For, as all right-thinking people were aware, lightning is sent by God to punish impiety or some other grave sin—the…
Slavery in America was perpetuated not merely by human badness but also by human blindness. ... Men convinced themselves that a system that was so economically profitable must be morally justifiable. ... Science was commandeered to prove the biological inferiority of the Negro. Even philosophical logic was manipulated…
You, in this country [the USA], are subjected to the British insularity in weights and measures; you use the foot, inch and yard. I am obliged to use that system, but must apologize to you for doing so, because it is so inconvenient, and I hope Americans will do everything in their power to introduce the French…
New technologies are advancing to the marketplace. but consumers can be wary of change. If they unequivocally demand alternatives to gasoline, for example, the marketplace will be activated, but ±ere is plenty of resistance to overcome. Recently, the president of Shell Oil, John Hoffmeister, expressed his views on…
Los Angeles air quality has improved in recent years because of new regulations on automobile and plant emissions, but the American Lung Association still ranks the Los Angeles area as the metropolitan region in America most polluted by year-round particles, short-term particles, and ozone. This persistent ranking…
Action regarding the environment requires objectivity, precision, accuracy, validity, replication, constructive criticism, and consensus. Scientists, engineers, and economists have to stay focused on putting accurate data into the hands of decision makers, while they explain their findings to the public, which, in the…
A hundred years ago, the electric telegraph made possible—indeed, inevitable—the United States of America. The communications satellite will make equally inevitable a United Nations of Earth; let us hope that the transition period will not be equally bloody.
The role of hypothesis in research can be discussed more effectively if we consider first some examples of discoveries which originated from hypotheses. One of the best illustrations of such a discovery is provided by the story of Christopher Columbus' voyage; it has many of the features of a classic discovery in…
During the Great Recession, nearly 1 in 12 people working in sales in America lost their job, accelerating a trend that had begun long before. In 1995, for example, 2.08 people were employed in “sales and related” occupations for every $1 million of real GDP generated that year. By 2002 (the last year for which…
The third explanation for America’s current job creation problems flips the stagnation argument on its head, seeing not too little recent technological progress, but instead too much. We’ll call this the “end of work” argument, after Jeremy Rifkin’s 1995 book of the same title. In it, Rifkin laid out a bold and…
Even if the coffers hadn’t been empty, if we’d had all the money to make all the uniforms we needed to implement Phase Two, who do you think we could have conned into filling them? This goes to the heart of America’s war weariness. As if the “traditional” horrors weren’t bad enough—the dead, the disfigured, the…
Starting anew with a clean slate has been one of the most harmful ideas in history. It treats previous knowledge as an impediment and imagines that only present knowledge deployed in theoretical purity can make real the wondrous new vision. Thus the French Revolution of 1789, the Russian Revolution of 1917, and the…
Indeed, there is a particular problem with finding endings in science. Where do these science stories really finish? Science is truly a relay race, with each discovery handed on to the next generation. Even as one door is closing, another door is already being thrown open. So it is with this book. The great period of…
There is another approach to the extraterrestrial hypothesis of UFO origins. This assessment depends on a large number of factors about which we know little, and a few about which we know literally nothing. I want to make some crude numerical estimate of the probability that we are frequently visited by…
Sometimes we can actually pin down the explanation of a weird coincidence. A great American scientist called Richard Feynman tragically lost his wife to cancer, and the clock in her room stopped at precisely the moment she died. Goose-pimples! But Dr Feynman was not a great scientist for nothing. He worked out the…
The Solar System is much vaster than the Earth, but the speeds of our spacecraft are, of course, much greater than the speeds of the sailing ships of the fifteenth and sixteenth centuries. The spacecraft trip from the Earth to the Moon is faster than was the galleon trip from Spain to the Canary Islands. The voyage…
The virtue of thinking about life elsewhere is that it forces us to stretch our imaginations. Can we think of alternative solutions to biological problems already solved in one particular way on Earth? For example, the wheel is a comparatively recent invention on the planet Earth. It seems to have been invented in the…
Our instincts and emotions are those of our hunter-gatherer ancestors of a million years ago. But our society is astonishingly different from that of a million years ago. In times of slow change, the insights and skills learned by one generation are useful, tried, and adaptive, and are gladly received when passed down…
