"They say" the one constant in the universe is change.
That applies to knowledge, too. The things we know as fact, the things we have always grown up with, they just may not be true. The function of a university is to teach; but what? And to teach is to question.
For years nothing was faster than light. Now, not only do new experiments suggest some "things" (I don't understand what "things" I admit) may be faster..but that light itself is not a constant, and its speed may change. OMG! Physics teachers may have strokes, but old Albert is probably chuckling.
And that guy who just won the Nobel Prize in Chemistry, when he first proposed his "theory", his fellow chemists hooted, even exiled him from their research group. He's laughing all the way to the bank with his $1.5 million award now.
Years ago a teacher told me "it takes the longest time to get an idea thru about 1/4" of a skull into a brain!" Once again a "new" federal study says women who took the drug DES years ago have put themselves and their daughters at higher risk of cancers. But I first heard that possibility in the late 1940s, and this "new" study is but the latest in a long list of such studies. Better questioning by doctors and universities in the '40s could have saved some lives here.
And old maxim in journalism puts it this way; "If your mother says she loves you, check it out!"
Not a bad approach for students, or universities, too.
I'm just sayin'...
