The source of science is everything.

For anyone to depend upon one single area of scientific discipline for a full education of phenomena is folly.

A multi disciplinary approach illuminates a larger field of study and understanding than a single scientific approach. Clearly philosophy, history and science fiction would be part of an interdisciplinary foundation. That does not make for non science.
It makes for more possiblilites for understanding.

I would trust a cosmologist who had a braod spectrum of knowledge that would include a dozen or more fields of study than I would a single mathmatician, however some mathmaticians like Einstien have more insight than a dozen multidisiplinarians.

Still, the math of Eistein was done by someone else. In his case, his first wife. Witten and Greene both are more diverse in their scientific approach than Einstein.


I made some of these points in a lengthy essay ten years ago which is as fresh today as when it was first written.
