We've got to remember three prominent scientists and their great contributions to China:

錢學森---rockets, missiles, and satellites

鄭學稼---A-bombs

于敏-----H-bombs

I did introduce the first two to you in my previous writings, and now I would like to share with you a brief biography of Mr.于敏 at: http://www.toutiao.com/a6340039198199775490/

Let's Wish Mr. 于敏, now at 90, a long and happy life.
