YOU SAID:
Max Planck discovered the relationship between frequency and energy. Nobody before had ever guessed that frequency would be directly proportional to energy (this means that as one of them doubles, the other does, too). If we choose to use what are called natural units, then the number representing the frequency of a photon would also represent its energy. The equation would then be:
INTO JAPANESE
マックス ・ プランクは、周波数とエネルギーの関係を発見しました。誰も前に今まで周波数だろう (これはことを意味、それらの 1 つが 2 倍、他、あまりにも) エネルギーに比例することを推測していた。かどうか自然単位系と呼ばれるものを使うことを選びますし、光子の周波数を表す数値となるも、
That didn't even make that much sense in English.
