Scientists tend to resist interdisciplinary inquiries into their own territory. In many instances, such parochialism is founded on the fear that intrusion from other disciplines would compete unfairly for limited financial resources and thus diminish their own opportunity for research.

Most people today still believe, perhaps unconsciously, in the heliocentric universe. Every newspaper in the land has a section on astrology, yet few have anything at all on astronomy.

If a problem is too difficult to solve, one cannot claim that it is solved by pointing at all the efforts made to solve it.

I have no trouble publishing in Soviet astrophysical journals, but my work is unacceptable to the American astrophysical journals.

I have always believed that astrophysics should be the extrapolation of laboratory physics, that we must begin from the present universe and work our way backward to progressively more remote and uncertain epochs.

We should remember that there was once a discipline called natural philosophy. Unfortunately, this discipline seems not to exist today. It has been renamed science, but science of today is in danger of losing much of the natural philosophy aspect.
