The spring sunshine in Paris was bright, with a gentle breeze stirring the plane tree leaves along the Seine River, creating ripples in the water.
Inside the hall of the French Academy of Sciences, the lights were brilliant, and the golden decorations shimmered alongside solemn marble statues, creating an atmosphere of grandeur.
Backstage, Arthur, who was about to take the stage, was chatting with several eminent figures of the Academy.
Contrary to Arthur's expectations of a harmonious meeting, the scientists were actually in a heated argument over the letter brought by Faraday.
The focus of the debate was whether light was a particle or a wave.
In the heat of the argument, they naturally recalled the French Academy of Sciences' annual essay competition of 1819, all remembering the essay title: "Determine the diffraction effects of light through precise experiments and deduce the motion of light when it passes near objects."
