PhD student wins online fans with science humor

The conservative image of chemical engineering PhD candidates at prestigious Chinese universities has been upended by the whimsical inventions and humor of Bi Xiaotian, a 25-year-old student at Beijing's Tsinghua University.

They made him an online hit a year ago, and he is now considering starting his own media firm so that he can carry on transmitting his knowledge in his unique style.

"I just use an ingenious way of speech to show how a person full of scientific and technical knowledge can let the public know what science and technology looks like in daily life," he said.
