Elderly experts bringing science to the masses

Organization's efforts in line with top leader's innovation drive

Many elderly Chinese spend their retirement looking after grandchildren or traveling the world, but for Bai Wuming, 62, his former career is a labor of love and he's helping popularize science among young people.

Bai officially retired two years ago from a 40-year career in geophysics with the Chinese Academy of Sciences, yet he continues to give lectures on earth science in schools across the country, including in remote rural areas.
