Notwithstanding these major arguments the wave theory initially did not meet with complete acceptance. ↗

It was at this moment that I wrote my first important paper in theoretical physics. I was 32 years old, 5 years beyond the alleged age of senility for theorists. ↗

Because of recent improvements in the accuracy of theoretical predictions based on large scale ab initio quantum mechanical calculations, meaningful comparisons between theoretical and experimental findings have become possible. ↗

Men act like brutes in so far as the sequences of their perceptions arise through the principle of memory only, like those empirical physicians who have mere practice without theory. ↗

Of course the lower classes have always felt downtrodden and aspired to a better life. But there is this theory that people respond to a class structure in England - there was a time when people knew who they were and knew whom they served and as long as management wasn't abusive, it was a good life for people. ↗

I'm a scientist, not a theologian. I don't know if there is a God or not. Religion requires certainty. ↗

If you start any large theory, such as quantum mechanics, plate tectonics, evolution, it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so. ↗

In making theories, always keep a window open so that you can throw one out if necessary. ↗
