Science Quotes by John Bradley (1 quote)
To Avogadro and Cannizzaro, as to Couper and Kekulé, the molecules and atoms considered in this great theory were real objects: they were thought of the same way as one thinks of tables and chairs.
— John Bradley
On the Operational Interpretation of Classical Chemistry', British Journal for the Philosophy of Science (1955), 6, 32. In Mary Jo Nye, From Chemical Philosophy to Theoretical Chemistry (1993), 58
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.
(1987) --
