Ductility Quotes (1 quote)
The world has been centuries in learning to use other metals; in learning to roll, draw, temper and polish them. Aluminum is new. but we are learning how to deal with it, how to secure the qualities of strength, hardness, ductility, lustre, etc., when required, much more rapidly than has occurred in the history of the other metals.
Conclusion of article, Chas. M. Hall, 'The Properties of Aluminum', Western Electrician (30 May 1891), 8, No. 22, 312.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would 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.
