The question of what weight to give to human interests and to nonhuman animal interests is difficult.67 Humans are literally outweighed by farmed animals: land-based farmed animals have 70 percent more biomass than all humans.68 Land-based farmed animals also outnumber humans greatly, by a factor of three to one, with…
Time is not the only life-enriching resource granted to us by technology. Another is light. Light is so empowering that it serves as the metaphor of choice for a superior intellectual and spiritual state: enlightenment. In the natural world we are plunged into darkness for half of our existence, but human-made light…
This is what prosperity is: the increase in the amount of goods or services you can earn with the same amount of work. As late as the mid-1800s, a stagecoach journey from Paris to Bordeaux cost the equivalent of a clerk’s monthly wages; today the journey costs a day or so and is fifty times as fast. A half-gallon of…
Outside Temperatures. Place a thermometer outside a window so students can make daily calculations and keep a chart reporting the actual temperature and the temperature change from the previous day. Students will see that the change can be a negative number without the temperature falling below 0—an often-confusing…
Now that the presidency of George W. Bush is over, the theory that we are better off with unintellectual leaders is just embarrassing, and the reasons for the embarrassment may be quantified. Measuring the psychological traits of public figures, to be sure, has a sketchy history, but the psychologist Dean Simonton has…
Now let’s turn to the present. According to the most recent edition of the Statistical Abstract of the United States, 2,448,017 Americans died in 2005. It was one of the country’s worst years for war deaths in decades, with the armed forces embroiled in conflicts in Iraq and Afghanistan. Together the two wars killed…
In absolute numbers, of course, civilized societies are matchless in the destruction they have wreaked. But should we look at absolute numbers, or at relative numbers, calculated as a proportion of the populations? The choice confronts us with the moral imponderable of whether it is worse for 50 percent of a…
The hypothesis of {108} abstraction says that every living creature is characterized by a number Q which is a measure of the complexity of the creature. To measure Q, we do not need to know anything about the internal structure of the creature. Q can be measured by observing from the outside the behavior of the…
"I give them fifty milli-Helens," he said. This went totally missing on everyone. "A milli-Helen is enough beauty to launch exactly one ship," Zane explained, and the older Crims all laughed. "Fifty's pretty good."
[Of her] Her statistics were more than a study, they were indeed her religion. For her Quetelet was the hero as scientist, and the presentation copy of his Physique sociale is annotated by her on every page. Florence Nightingale believed—and in all the actions of her life acted upon that belief—that the administrator…
There are some subtle facts about scale analysis that make it more powerful than simply comparing orders of magnitude. A most remarkable example is that scale analysis can be applied, through a systematic use of dimensions, even when the precise equations governing the dynamics of a system are not known. The great…
Benoit Mandelbrot asked his famous question “How long is the coast of Britain?” long before this symposium was written, but it perfectly captures the sort of puzzle people in this crowd love. The question seems simple. Just look it up in the encyclopedia. But as Mandelbrot observed, the length of the coast of Britain…
We recognize in the concept of heat which appears here a similarity to other physical concepts. Heat is, according to our view, a substance, such as mass in mechanics. Its quantity may change or not, like money put aside in a safe or spent. The amount of money in a safe will remain unchanged so long as the safe…
A dictionary takes words you're unfamiliar with and puts them in terms you're familiar with. Dictionary of Numbers takes numbers you're unfamiliar with and puts them in terms you can understand. Dictionary of Numbers scans the web pages you visit looking for numbers it can understand. When it finds one, it will give…
The four NDEA Titles featured in this report contributed to general upward trends (e.g., in the rate of high school, college, and graduate completion; in the level of student preparedness in science, mathematics, and modern languages; in the number of teachers and degree-granting institutions; in the number of…
The rudest numerical scales, such as that by which the mineralogists distinguish different degrees of hardness, are found useful. The mere counting of pistils and stamens sufficed to bring botany out of total chaos into some kind of form. It is not, however, so much from counting as from measuring, not so much from…
