Douglas Hofstadter lectures at Uppsala University on how analogy and daring thinking drove Einstein's discovery of light quanta. He argues deep insight in physics comes from imaginative leaps rather than rigid logic.
Cited in discussions of analogy-making in science, and revisited by fans of Hofstadter.

Douglas Hofstader has a talk on this topic called "Albert Einstein on Light; Light on Albert Einstein" that I often revisit: this video (watch 10:30 to 12:00 if you're pressed for time, but I recommend the whole thing)
I have following 3 suggestions regarding analogies. [1] Analogies in Fundamental physics Lecture by Douglas Hofstadter: Albert Einstein on Light; Light on Albert Einstein : this video “Where does deep insight in physics come from? For those who view physics as a highly rational science grounded in strict mathematics, it is tempting to think that it comes from the purest and most precise of reasoning, following ironclad laws of thought that compel the clear mind completely rigidly. And yet the truth is quite otherwise. One finds, when one looks closely at any major discovery in physics, that the greatest of physicists are the most daring and are constantly being guided by blurry, instinctive, nearly irrational mental forces. Albert Einstein ideally exemplifies this thesis. In this talk, I will discuss the eternal mystery of light, which, over the course of millennia, was puzzled over, pondered on, and slowly worked out by a series of great minds, and finally, in the nineteenth century, was definitively settled with clarity and rock-solid certainty. And yet one day in the early spring of 1905, quite out of the blue, came an absurd-seeming new suggestion from an unknown Swiss patent clerk, third class, clashing violently with that rock-solid piece of collective wisdom. How did the brazen patent clerk come up with this crazy idea? How it was received by the physics world? What was its eventual fate? And what can we learn about the workings of the human mind from this twisty story fi
And he has a point. Analogies are common in fundamental physics. This particular lecture exemplifies that. Lecture by Douglas Hofstadter: Albert Einstein on Light; Light on Albert Einstein this video
