We Interrupt This Blog For Some Breaking News ...
Friday, February 20, 2009
Hey folks. Sorry for the disappearance ...
... assuming you missed me at all. Ups. Downs. Events. Crises. The usual fortnight: SNAFU! (If you are too young to know what that stands for, go look the abbreviation up. Err ... not if you are too, too young, though. In which case you shouldn't even be on my blog.) Through all this, several posts have been brewing, too. Some are still in my mind, some on my trusty old MacBook Pro. But there just hasn't been time.

Yayyyy. It's Darwin Day!
JUST A THEORY? According to the United States National Academy of Sciences... Some scientific explanations are so well established that no new evidence is likely to alter them. The explanation becomes a scientific theory. In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature supported by facts gathered over time. Theories also allow scientists to make predictions about as yet unobserved phenomena.
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory." It is as factual an explanation of the universe as the atomic theory of matter or the germ theory of disease. Our understanding of gravity is still a work in progress. But the phenomenon of gravity, like evolution, is an accepted fact.The other big issue - at least among many of the people around me - is the feeling that, since many of the atheists must believe in Evolution (after all, they have no one else to credit for Life), the whole Evolution enterprise, itself, must be an anti-God, anti-religious ideology and needs to be shunned offhand. Hmmm. Most atheists I know also believe that the world is round, but I don't see anyone refuting that. Well, almost anyone.

Waste of time? I think I've found a couple of interesting ideas about using these in classrooms. Maybe I'll share them here some day, once they've taken better shape. Feel free to suggest some that come to your mind.
