单电子宇宙 (Dān Diànzǐ Yǔzhòu)

Background
I received a telephone call one day at the graduate college of Princeton from Professor Wheeler, in which he said, "Feynman, I know why all electrons have the same charge and the same mass" "Why?" "Because, they are all the same electron!"

"Dān Diànzǐ Yǔzhòu" is an original song featuring Yuezheng Ling.
