Teaching needs an ecosystem that supports evidence-based practice. It will need better systems to disseminate the results of research more widely, but also a better understanding of research, so that teachers can be critical consumers of evidence.

I agree, the world would be a better place if doctors were less enthusiastic about adopting very new drugs.

The value of a scientific publication goes beyond this simple benefit, of all relevant information appearing, unambiguously, in one place. It's also a way to communicate your ideas to your scientific peers, and invite them to express an informed view.

If you put me in charge of the medical research budget, I would cancel all primary research, I would cancel all new trials, for just one year, and I would spend the money exclusively on making sure that we make the best possible use of the clinical evidence that we already have.

Cassini was an international undertaking, led by NASA and the European Space Agency and designed to be, in every dimension, a dramatic advance over Voyager. At the size of a school bus, it was bigger than Voyager and outfitted with the most sophisticated scientific instruments ever carried into the outer solar system.

The thing about television is that you can't fake it. Your sense of discovery must be genuine; you can't pretend to be surprised.

I like the idea of using all this science and technology to allow for our clients to have a deeper insight into the market.

Imagine if baseball were taught the way science is taught in most inner-city schools. Schoolchildren would get lectures about the history of the World Series. High school students would occasionally reproduce famous plays of the past. Nobody would get in the game themselves until graduate school.
