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…
There is fundamentally no business case for private enterprise to advance a space frontier. When you advance a frontier, you are making mistakes that the capital markets choose not to value. You have to create patents to enable things that you don't know will work. Anytime you are the first person to do something on…
Is the climate crisis real? Yes, of course it is. Pause for a moment to consider these events of just the past 12 months: • Heat. According to NASA, 2010 was tied with 2005 as the hottest year measured since instruments were first used systematically in the 1880s. Nineteen countries set all-time high temperature…
Vygotsky was one of the few researchers of his era to study dramatic play in children. He predicted that the ability of the under-5 crowd to engage in imaginative activities was going to be a better gauge of academic success than any other activity—including quantitative and verbal competencies. The reason, Vygotsky…
In the old days, extensive parental contact was discouraged because of fears about injury or infection. Now, however, some hospitals are encouraging parents to spend up to several hours a day holding their preterm infants, preferably upright and skin-to-skin against their bare chest. This approach has been dubbed…
As we learn more about maternal hormones and their influence on the developing brain, scientists are beginning to propose actual biological mechanisms for the kind of folk prophecies that have been around for ages. One recent study, for instance, suggests that a child's shyness is determined, in part, by maternal…
It is from a public health standpoint, rather than from knowledge of indipercent of pregnant wompr. i^ percent of pregnant women in the United States reported drinking alcohol in the month preceding the survey, and 3 percent admitted to at least one binge. (Alcohol consumption is notoriously underreported in this kind…
From an evolutionary point of view, it would seem that last-feeding should be one of the more instinctual behaviors, like eating or sleeping or sex. In most mammals, if mothers don't know how to offer their milk or babies don't know how to suckle, the infant dies. If die purpose of reproduction is to pass on genes, it…
More significantly, the breast—bottle controversy has moved far away from the question of what is best for babies. The decision for substitute milk is influenced by the pressures of corporations, their advertising, and their lobbies. The money game behind the production of formula has overpowered what might be best…
The business sector is dazzlingly productive, but it also periodically blows up our financial system. Yet if we seek another model, one that emphasizes universal health care and educational opportunity, one that seeks to curb income inequality, we don’t have to turn to Sweden. Rather, look to the United States…
Most human and natural communities now consist both of long-term residents and of new arrivals, and ecosystems are emerging that never existed before. It is impractical to try to restore ecosystems to some ‘rightful' historical state. For example, of the 30 planned plant eradication efforts undertaken in the Galapagos…
Many plants new to North America first sprouted up alongside wharves and shipyards. From there they made their way inland along new roads hacked out of the wilderness, and later along canals and railroad embankments, taking up residence in any sort of disturbed soil. Native plants adapted to quiet precolonial forests…
I think it's impossible to be a scientist and to confront, even occassionally, the grandure, subtlety, elegance and magnificience of the universe without feeling a sense of reverence and awe, but that's very different from concluding that there's a god who issues punishments and rewards after your dead or that prayer…
Profit-motivated designer viruses, many of which are completely legal and aboveboard today, have their shady origins in the crooked Ponzi scheme.* Charles Ponzi was an Italian immigrant who opened a business in Boston in 1919 called the Securities Exchange Company. He offered to repay people's investments in 90 days…
What kinds of memes are there? I've divided memes into three classes: distinctions, knives used to slice up reality; strategies, beliefs about which causes will produce which effects; and associations, attitudes about everything in life. Each class of meme works to program you in a different way. [...]…
Declaration of Independence puts it - 'the laws of nature and of nature's GOD'. Dr Benjamin Franklin was revered in Europe and America as the founder of the new field of electrical physics. At the Constitutional Convention of 1789 John Adams repeatedly appealed to the analogy of mechanical balance in machines; others…
Daniel Kunitz is a friend of mine from college. He's spent his life as an innovative junior and senior high school social sciences teacher. Want the students to understand the Constitution of the United States? You could have them read it, Article by Article, and then discuss it in class but, sadly, this will put most…
In addition to teaching us what to do when evaluating a claim to knowledge, any good baloney detection kit must also teach us what not to do. It helps us recognize the most common and perilous fallacies of logic and rhetoric. Many good examples can be found in religion and politics, because their practitioners are so…
T.H. Huxley's formulation was The foundation of morality is to . . . give up pretending to believe that for which there is no evidence, and repeating unintelligible propositions about things beyond the possibilities of knowledge. Clement, Hume, Paine and Huxley were all talking about religion. But much of what they…
• Despite plentiful opportunities for misuse, science can be the golden road out of poverty and backwardness for emerging nations. It makes national economies and the global civilization run. Many nations understand this. It is why so many graduate students in science and engineering at American graduate schools…
