Douglas,
I commend your words highly. I've found quite the opposite attitude is often prevalent. Commonly fine words are spoken but not practised. Any hypothesis beyond the ruling paradigm causes a sprint for cover within the brackets of conformity. A minor example was the top two peer scored essays last year, including mine, entirely ignored in the judging.
I note and agree your comment above that; "Big advances often/always come (from) people trying different, unusual, unexpected approaches to science questions." Which is well documented as being the case, but many fail to make it or take years, while often banal repeats of present doctrine flood the journals with information overload. Dan Shecktman's rejection for 40 years is typical of the few that do emerge.
I believe my own essay this year is self evidently groundbreaking; showing that a classical derivation of quantum mechanical predictions is possible allowing convergence with SR and fundamental advancement across a broad range of a sciences. I predict all those schooled in the present nonsensical QM will again run for the nearest brackets or beach, as do editors. Are you really any different Douglas? A top score coming if you are, or were they really just words? That is human nature. I agree with Judy above and suggest thinking outside the Earth centred frame may help intellectual evolution.
I look forward with interest to you comments on my, rather different, essay.
Best wishes
Peter
