Why do I have more intuition for nanoscale and quantum systems than classical central force problems? Because I hardly ever work on the latter. Physical intuition is the intellectual equivalent of muscle mass in some specific group. If I don’t exercise the Poisson bracket/Runge-Lenz vector part of my physics brain, it atrophies.
That is Doug Natelson at nanoscale views; reminded me of those words of wisdom by Avvai–வைத்ததொரு கல்வி மனப்பழக்கம்–education is but the practice of the mind.
