I have a theory that the best ads come from personal experience. Some of the good ones I have done have really come out of the real experience of my life, and somehow this has come over as true and valid and persuasive. ↗

In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely. ↗

In a certain sense, aspects of my solo playing were developed in order to test the theory about how long particular elements could be, as parts of so-called free improvisations. ↗

In so far as such a theory is empirically correct it will also tell us what empirical facts it should be possible to observe in a given set of circumstances. ↗

It is probably safe to say that all the changes of factual knowledge which have led to the relativity theory, resulting in a very great theoretical development, are completely trivial from any point of view except their relevance to the structure of a theoretical system. ↗

One's life and passion may be elsewhere, but New York is where you prove if what you think in theory makes sense in life. ↗

Scientific theory is a contrived foothold in the chaos of living phenomena. ↗

If there was ever any truth to the trickle-down theory, the only evidence of it I've ever seen was in that period of 1960 to 1965. All of sudden they were handing out major label recording contracts like they were coming in Cracker Jack boxes. ↗

The things that will destroy America are prosperity-at-any-price, peace-at-any-price, safety-first instead of duty-first, the love of soft living, and the get-rich-quick theory of life. ↗

My present work concerns the problems connected with the theory of elementary particles, the theory of gravitation and cosmology and I shall be glad if I can manage to make some contribution to these important branches of science. ↗
