Science Quotes by David H. Janzen (1 quote)
This study was supported by NSF MBS75-14268 and inspired by paying 95 cents for a rotten avocado.
— David H. Janzen
In 'Why Fruits Rot, Seeds Mold, and Meat Spoils', The American Naturalist (Jul-Aug 1977), 111, No. 980, 707. The author suggests that food spoilage is the result of microbes competing to keep the resource to themselves by engendering the rotting process to repel larger animals from consuming the food item.
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) --
