/ In science it often happens that       \
| scientists say, 'You know that's a     |
| really good argument; my position is   |
| mistaken,' and then they actually      |
| change their minds and you never hear  |
| that old view from them again. They    |
| really do it. It doesn't happen as     |
| often as it should, because scientists |
| are human and change is sometimes      |
| painful. But it happens every day. I   |
| cannot recall the last time something  |
| like that happened in politics or      |
| religion.                              |
