In all my research I have never come across matter. To me the term matter implies a bundle of energy which is given form by an intelligent spirit.

A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.

A new truth always has to conend with many difficulties. If it were not so, it would have been discovered much sooner.

A scientist is happy, not in resting on his attainments but in the steady acquisition of fresh knowledge.

Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.

It is never possible to predict a physical occurrence with unlimited precision.

A new scientific truth is usually not propagated in such a way that opponents become convinced and discard their previous views. No, the adversaries eventually die off, and the upcoming generation is familiarised anew with the truth.
