Level two chaos is chaos that reacts to predictions about it, and therefore can never be predicted accurately. Markets, for example, are a level two chaotic system. What will happen if we develop a computer program that forecasts with 100 per cent accuracy the price of oil tomorrow? The price of oil will immediately…
Choral reading gives students the experience of reading aloud without the stress of reading alone. Based upon the previously described research demonstrating that repeated stimulation of neuronal networks increases their efficiency, it makes sense that the experience of reading aloud together reinforces patterns. When…
During a median follow-up of 20.7 years (interquartile range, 18.1-22.6 years), 190 SCDs, 281 fatal CHDs, 407 fatal CVDs, and 929 all-cause mortality events occurred. A total of 601, 1513, and 201 participants reported having a sauna bathing session 1 time per week, 2 to 3 times per week, and 4 to 7 times per week…
Simplified spelling means shorter spelling. Of the 32 Rules printed in Part 3 of this Handbook, 27 drop letters from words as now speld; 3 involv trans- positions of letters to reconcile conflicting analogies; and 2 involv substitutions of one letter for another, with the same object. In no instance has the Board…
Well, the value of graduate school really depends on what you are studying and what you expect to get out of graduate school. I encourage young people to engage in the act of dynamic thinking. That means don't just apply the rules that worked in your field 20 years ago. Journalism is a great example. The media has…
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…
The sun is always just about to rise. Mercury rotates so slowly that you can walk fast enough over its rocky surface to stay ahead of the dawn; and so many people do. Many have made this a way of life. They walk roughly westward, staying always ahead of the stupendous day. Some of them hurry from location to location…
Bayes’s much more famous work, “An Essay toward Solving a Problem in the Doctrine of Chances,”24 was not published until after his death, when it was brought to the Royal Society’s attention in 1763 by a friend of his named Richard Price. It concerned how we formulate probabilistic beliefs about the world when we…
Of all regions of the earth none invites speculation more than that which lies beneath our feet, and in none is speculation more dangerous; yet, apart from speculation, it is little that we can say regarding the constitution of the interior of the earth. We know, with sufficient accuracy for most purposes, its size…
The pursuit of science has often been compared to the scaling of mountains, high and not so high. But who amongst us can hope, even in imagination, to scale the Everest and reach its summit when the sky is blue and the air is still, and in the stillness of the air survey the entire Himalayan range in the dazzling…
Anthropology has reached that point of development where the careful investigation of facts shakes our firm belief in the far-reaching theories that have been built up. The complexity of each phenomenon dawns on our minds, and makes us desirous of proceeding more cautiously. Heretofore we have seen the features common…
We need science education to produce scientists, but we need it equally to create literacy in the public. Man has a fundamental urge to comprehend the world about him, and science gives today the only world picture which we can consider as valid. It gives an understanding of the inside of the atom and of the whole…
He depicts himself watching in rapture the two adult grey-tailed eagles in the bright sunlight, followed by their young offspring. This moment is transformed into an image of Davy the man of science, hoping to inspire his young scientific protégés to ever greater discoveries. The mighty birds still upward rose In slow…
The energy liberated when substrates undergo air oxidation is not liberated in one large burst, as was once thought, but is released in stepwise fashion. At least six separate steps seem to be involved. The process is not unlike that of locks in a canal. As each lock is passed in the ascent from a lower to a higher…
Signs also are to be drawn from the increase and progress of systems and sciences. For what is founded on nature grows and increases, while what is founded on opinion varies but increases not. If therefore those doctrines had not plainly been like a plant torn up from its roots, but had remained attached to the womb…
Study nature to find your voice. One reason the natural history genre thrives today is the tremendous variety of voices it makes possible: the wild exactness of Annie Dillard, the calm thankfulness of Terry Tempest Williams, the scientific precision of Bernd Heinrich. But again, this is not just the province of…
The authors comment that from this perspective, it could be stated that multiccellular beings are also ecosystems. That is, we are formed by different types of cells that cooperate and compete for resources; we are colonized by diverse types of bacteria (in the intestines, in the skin, etc.) whose activity is linked…
Once upon a time, we soared into the solar system, for a few years. Then we hurried back. why? What happened? What was Apollo really about? The scope and audacity of John Kennedy's May 25th 1961 message to a joint session of Congress on "Urgent National Needs" -- the speech that launched the Apollo program--dazzled…
One day I'll be convinced there's a certain type of symmetry that everybody believes in, the next day I'll try to figure out the consequences if it's not, and everybody's crazy but me. But the thing that's unusual about good scientists is that while they're doing whatever they're doing, they're not so sure of…
