In the traditional theory, which still is the prevailing one, there were alleged to exist inherent defects in perception and observation as means of knowledge, in reference to the subjectmatter they furnish. This material, in the older notion, is inherently so particular, so contingent and variable, that by no…
Science is my territory, but science fiction landscape of my dreams. The year 1995 was the hundredth anniversary of the publication of H. G. Wells's The Time Machine, perhaps the darkest view of the human future ever imagined. Wells used a dramatic story to give his contemporaries a glimpse of a possible future. His…
Because the absurdities and intricacies of our pres- ent spelling hav made a mastery of them the most dif- ficult and long-continued task of the average student, a false value has been placed on spelling ability. "Cor- rectness" in reality, mere conformity in spelling is too generally assumed to be an indication of…
A natural pas may afford the most convenient way to cros a mountain, but it wil be vastly improved by bilding a good road thru it. Fruits and vegetables that grow wild in their natural state ar greatly and universally improved and adapted to human needs by cultivation. Every process of manufacture, from roast- ing a…
"These remarkable creatures combine the characteristics of animals and plants and so I call them animal-plants. ..." "All right. Don't get angry. Just explain how your creatures avoid getting dried up like mummies." "That is simple. Their skin is covered with a glassy layer, thin and flexible but absolutely…
In programmable matter, the same cubic meter of machinery can become a wind tunnel at one moment, a polymer soup at the next; it can model a sea of fermions [elementary particles], a genetic pool, or an epidemiology experiment at the flick of a console key. Ten times as large a simulation will simply require ten cubic…
How many seconds are there in a lifetime? 10^9 sec A second is an arbitrary time unit, but one that is based on our experience. Our visual system is bombarded by snapshots at a rate of around three per second, caused by rapid eye movements called saccades. Athletes often win or lose a race by a fraction of a second…
Wolfgang Schivelbusch (1995) argues that one of the most important transformations of networked urban life came with the rise of the gas lamp. The introduction of gas ended the autonomy of oil lamps and candles whereby each household effectively supplied its own energy needs. Gas represented the industrialization of…
“The body tries to stay alive. It’s not so… It’s natural. Maybe you’ll see it now. First the human brain dies, then the animal brain, then the lizard brain. Like your Rm, only backward. The lizard brain tries to its very last bit of energy to keep things going. I’ve seen it. Some kind of desire. It’s a real force…
This IPCC finding makes several different assertions, each of which is worth considering in turn. First, it claims that atmospheric concentrations of greenhouse gases like CO2 are increasing, and as a result of human activity. This is a matter of simple observation. Many industrial processes, particularly the use of…
If you want to find out anything from the theoretical physicists about the methods they use, I advise you to stick closely to one principle: don't listen to their words, fix your attention on their deeds. To him who is a discoverer in this field the products of his imagination appear so necessary and natural that he…
In the Ne± Netherlands, a unique partnership between Shell Oil Company and Dutch greenhouse businesses enables surplus carbon dioxide produced at the Shell refinery in Pernis, outside Rotterdam, to be pumped into greenhouses as an alternative to pumping it directly into the atmosphere as waste. The partnership was…
In discussing the state of the atmosphere following a nuclear exchange, we point especially to the effects of the many fires that would be ignited by the thousands of nuclear explosions in cities, forests, agricultural fields, and oil and gas fields. As a result of these fires, the loading of the atmosphere with…
There are certain general Laws that run through the whole Chain of natural Effects: these are learned by the Observation and Study of Nature, and are by Men applied as well to the framing artificial things for the Use and Ornament of Life, as to the explaining the various Phænomena: Which Explication consists only in…
This is the published version: ‘By degrees as the pleasurable sensations increased, I lost all connection with external things; trains of vivid visible Images rapidly passed through my mind and were connected with words in such a manner, as to produce perceptions perfectly novel. I existed in a world of newly…
Once upon a time, about ten or fifteen billion years ago, the universe was without form. There were no galaxies. There were no stars. There were no planets. And there was no life. Darkness was upon the face of the deep. The universe was hydrogen and helium. The explosion of the Big Bang had passed, and the fires of…
Sed tamen salis petrae. VI. Part V. NOV. CORVLI. ET V. sulphuris, et sic facies toniitrum et coruscationem: sic facies artificium. But, however, of saltpetre take six parts, live of young willow (charcoal), and five of sulphur, and so you will make thunder and lightning, and so you will turn the trick. Bacon's recipe…
Though one might imagine "living" organisms such as intelligent computers produced from other elements, such as silicon, it is doubtful that life could have spontaneously evolved in the absence of carbon. The reasons for that are technical but have to do with the unique manner in which carbon bonds with other…
Actually, the nested arrangement of life was recognized long before Darwin. Starting with the Swedish botanist Carl Linnaeus in , biologists began classifying animals and plants, discovering that they consistently fell into what was called a “natural” classification. Strikingly, different biologists came up with…
Toward the effecting of works, all that man can do is to put together or put asunder natural bodies. The rest is done by nature working within.
