Will the twain-teaching & research-ever meet?
I mean there are great teachers. And there are excellent researchers/scholars/scientists. But combining great teaching and excellent research in one individual-isn't it a rare phenomenon. Except ,of course,persons like Richard Feynman who was a great teacher and excellent physicist.
One hears of hawking as a great physicist but never heard of him as a great teacher. So also Einstein. Or Watson of the double helix fame, to cite an example in another domain.
I mean why teaching and research dont gel so easily?
Does anyone have an answer?
