Not only does background knowledge grow in the brains of our students through their experiences, but the vocabulary words that are stored as a result of such experiences provide avenues to comprehend the curriculum from the text, as well as lecture and discussion. We can look at the work of Piaget (1970), who…
He who says “Better to go without belief forever than believe a lie!” merely shows his own preponderant private horror of becoming a dupe. . . . It is like a general informing his soldiers that it is better to keep out of battle forever than to risk a single wound. Not so are victories either over enemies or over…
The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence. Many scientific theories are so well established that no new evidence is likely to alter them…
One property of Bayes’s theorem, in fact, is that our beliefs should converge toward one another—and toward the truth—as we are presented with more evidence over time. In figure 8-8, I’ve worked out an example wherein three investors are trying to determine whether they are in a bull market or a bear market. They…
All interpretations made by a scientist are hypotheses, and all hypotheses are tentative. They must forever be tested and they must be revised if found to be unsatisfactory. Hence, a change of mind in a scientist, and particularly in a great scientist, is not only not a sign of weakness but rather evidence for…
When more evidence is garnered, whether through the analysis of additional characters, through the discovery of new specimens, or by pointing out errors and problems with the original data sets, new trees can be calculated. If these new trees better explain the data (taking fewer evolutionary transformations), they…
Babies start out believing that there are profound similarities between their own mind and the minds of others. That belief gives them a jump start in solving the Other Minds problem. But during the first three years they also observe the differences in what people do and say. Those differences stem from the fact that…
...there is a distressingly long list of people who have been wrongly convicted on eye-witness testimony and subsequently freed - sometimes after many years - because of new evidence from DNA. In Texas alone, thirty-five condemned people have been exonerated since DNA evidence became admissible in court. And that's…
I think that science tolerates the unknown in a way that religion doesn't. My argument is not with people who search for god. My argument is with people who feel that our understanding of god is completed. And those are the people who make so much of our existence on this planet such a hell, because they really think…
People who don't know a lot about science treasure what they do know, what they learned early as children, like: a) Eskimos have lots of words for snow. b) Wait 20 minutes after lunch before going swimming. c) There are nine planets, and the ninth one is Pluto. d) The biggest dinosaur ever was the Brontosaurus. e)…
