The rub, of course, is that everybody else thinks that science should provide the answers. Remember the Concorde? Back in the early 1970s, Congress was debating supersonic transport, trying to decide whether such aircraft would represent a danger when flown over the United States. Would their big engines flying high…
Now science fiction movies are mostly just shoot-‘em-ups, but back in the day sci-fi was a medium to explore social issues. SF allowed us to examine the core elements of controversial issues without all the emotional baggage that went along with them. It’s easy to dismiss the genre when you have grown-up fans walking…
To prove to an indignant questioner on the spur of the moment that the work I do was useful seemed a thankless task and I gave it up. I turned to him with a smile and finished, 'To tell you the truth we don't do it because it is useful but because it's amusing.' The answer was thought of and given in a moment: it came…
Many people find the topic of evolution and religion troubling and confusing. Some were raised in very strict churches that preached that evolution is atheistic and that to even think about the evidence of evolution is sinful. Fundamentalists have long tried to drive a wedge between traditional Christians and science…
Honesty is the essence of secularism. It is a willingness to set aside any and every comfort in order to know the truth that allowed us to see our way out of religious belief. Somewhat more difficult is ensuring that we practice the same level of honesty in all other aspects of our lives. I say “somewhat more…
The earliest stage Kohlberg described was one in which right and wrong are defined by punishment rather than by any larger principle. If something is followed by punishment, it was wrong; if it is not, it was right. The light-fingered 5-year-old mentioned before was at this stage. A second stage considers reward as an…
The truth is that the greatest enemies to the doctrines of Jesus are those calling themselves the expositors of them, who have perverted them for the structure of a system of fancy absolutely incomprehensible, and without any foundation in his genuine words. And the day will come when the mystical generation of Jesus…
Ingredients: molasses from the United States anise from Spain licorice from France vanilla (bourbon) from Madagascar cinnamon from Sri Lanka cloves from Indonesia wintergreen from China pimento berry oil from Jamaica balsam oil from Peru And that’s just for a bottle of peacetime root beer.
Sometime in the summer of 1786 the fifty-year-old John Adams, graduate of Harvard University, man of science and future second President of the United States, turned up one morning uninvited at The Grove. He was shown round all Herschel’s new telescopes, and they embarked on an impassioned discussion of the…
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…
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 experience of space exploration gives no unique philosophy; to some extent, each group tends to see its own philosophical view reflected, and not always by the soundest logic: Nikita Khrushchev stressed that in the space flight of Yuri Gagarin no angels or other supernatural beings were detected; and, in almost…
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…
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…
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…
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…
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…
