Via this site, here’s Richard Feynman on discovering new laws of physics:

First you guess. Don’t laugh, this is the most important step. Then you compute the consequences. Compare the consequences to experience. If it disagrees with experience, the guess is wrong. In that simple statement is the key to science. It doesn’t matter how beautiful your guess is or how smart you are or what your name is. If it disagrees with experience, it’s wrong. That’s all there is to it.

Via This Modern World, Editor and Publisher discusses a double standard:

Where, in the week after the Great Newsweek Error, is the comparable outrage in the press, in the blogosphere, and at the White House over the military’s outright lying in the coverup of the death of former NFL star Pat Tillman? Where are the calls for apologies to the public and the firing of those responsible? Who is demanding that the Pentagon’s word should never be trusted unless backed up by numerous named and credible sources?

Where is a Scott McClellan lecture on ethics and credibility?

…

Patrick Tillman Sr., the father -- a lawyer, as it happens -- said he blames high-ranking Army officers for presenting “outright lies” to the family and to the public. “After it happened, all the people in positions of authority went out of their way to script this,” he told the Post. “They purposely interfered with the investigation, they covered it up. I think they thought they could control it, and they realized that their recruiting efforts were going to go to hell in a handbasket if the truth about his death got out. They blew up their poster boy.”

“Maybe lying’s not a big deal anymore,” he said. “Pat’s dead, and this isn’t going to bring him back. But these guys should have been held up to scrutiny, right up the chain of command, and no one has.”

Mary Tillman, the mother, complained to the Post that the government used her son for weeks after his death. She said she was particularly offended when President Bush offered a taped memorial message to Tillman at a Cardinals football game shortly before the presidential election last fall.

The problem isn’t really a double standard. The current administration is above all standards of conduct. That leaves them free to pound on the table about the failings of others.
