William,
I'm sorry I skipped yours on first pass but really glad of the chance to read it now. You seem to have a good fundamental understanding of the issues and expressed them very well.
I think Bronowski's view that science is about finding unity in hidden likeness is massively important, and reflects; "A young Einstein, to paraphrase, wrote to his friends that there were great joys in connecting two things which before seemed entirely separated."
I take up that point i my own essay showing how relativity and QM can be unified classically free of paradox, which I see as your; "pursuing the major goal of science now", by overcoming the current limitation that "only about 12% of the brain is commonly used" and recognizing that; "interdisciplinary research is very important," by invoking effects from across physics for a coherent solution, resolving the problem that; "Planck's equation, after all these years, is still begging the question of what the quantum is." as Bohr never did commit to any 'structure'. I hope you may like my allegory, please do comment or question.
Our essays are quite different, and many haven't seen the 'quantum leap' that advancement of thinking and understanding nature can bring. History has proven that better understanding is the driver advancements, yet we will treat symptoms not fundamental cause. Very well done for your clear hitting of all the main points I employ and more. It should certainly be up in the 5's I think.
Best wishes
Peter
