I tend to like the historical approach, too. So did Bohr? "Just as many sports players go through warming-up exercises before entering the arena, so Bohr would relive the struggles which had taken place before the content of quantum mechanics was understood and accepted. I can say that in Bohr's mind this struggle started afresh every single day." -some book on 20th century physicists I don't recall ..but reading the original papers? I can't imagine ever deciphering Newton or Maxwell (before Heaviside fixed up the equations, it was some horrific mess of like, 20 equations with 20 unknowns). There are great benefits in a clean, logical development. On the other hand, I hear Dirac's papers were remarkably clear. Maybe reading the originals is easier for math? "..if one wishes to make progress in mathematics, one should study the masters and not the pupils" -Abel
