When Li Qiwei declared before everyone that he would end the debate over whether light was a wave or a particle, the atmosphere in the classroom was instantly set ablaze.
Quite a few students from other universities were indignant, convinced that Li Qiwei was talking nonsense.
"Such shameless boasting! This is a problem that has been studied for over a thousand years and debated for centuries. So many great scientists have failed to solve it—what makes him think he can end it?"
"From a philosophical perspective, the world is unknowable. Everything changes as it develops, and we can only understand one aspect of it. Bruce Li is being a little too proud."
"Wasn't it said that Easterners were all reserved and restrained? This Bruce Li is completely different from what I imagined."
Unlike the mocking students, the physicists led by Professor Keith were all immensely excited, their eyes brimming with anticipation.
They knew that the Photoelectric Effect Li Qiwei had proven showed that light truly possessed particle properties, and that the wave theory was not correct.
But how was he going to end it?
Only after the classroom had gradually quieted down did Li Qiwei continue slowly, "In the paper I recently published in Nature, I introduced the concept of light quanta."
"Those outside the field of physics may not understand. Light quanta treat light as individual particles, which happens to coincide with the particle theory of light."
"However, I would now rather call light quanta photons directly."
"Using the concept of photons, I successfully explained the Photoelectric Effect, a difficult problem that had plagued the physics community for more than a decade."
"And the latest experimental results have already proven that my photon theory is correct. Therefore, light is indeed a particle."
"At this point, some of you may
