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

To try to write a grand cosmical drama leads necessarily to myth. To try to let knowledge substitute ignorance in increasingly larger regions of space and time is science.

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.

Gravitational systems are the ashes of prior electrical systems.

We have to learn again that science without contact with experiments is an enterprise which is likely to go completely astray into imaginary conjecture.

It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.

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.
