朱棣文(Steven Chu,1948年2月28日—)1997年諾貝爾物理學獎

 "My physics teacher, Thomas Miner was particularly gifted. To this day, I remember how he introduced the subject of physics. He told us we were going to learn how to deal with very simple questions such as how a body falls due to the acceleration of gravity. Through a combination of conjecture and observations, ideas could be cast into a theory that can be tested by experiments. The small set of questions that physics could address might seem trivial compared to humanistic concerns. Despite the modest goals of physics, knowledge gained in this way would become collected wisdom through the ultimate arbitrator – experiment."

In his Nobel Prize biography, Steven Chu, who was born on this day in 1948, remembers his physics teacher.

第12任美國能源部長

朱棣文 FREng ForMemRS (英語:Steven Chu,1948年2月28日),男,出生及成長於美國聖路易斯美國華裔物理學家,因「發展了用雷射冷卻和捕獲原子的方法」而獲得1997年諾貝爾物理學獎。2009-2013年美國能源部部長。加州大學華裔學者協會創會理事之一。

朱棣文擔任能源部長前,他是美國加州大學伯克利分校物理學和分子和細胞生物學教授,和勞倫斯伯克利國家實驗室的主任,他的研究領域的主要是研究在單分子水平的生物系統。[1]在此之前,他曾在斯坦福大學教授物理學。他積極主張進行更多對於可再生能源核能的研究,他認為從化石燃料轉變出來是應對氣候變化的關鍵。[2][3][4]例如,他曾設想一個全球性的「葡萄糖經濟」,一個低碳經濟形式,即將熱帶植物生產出的葡萄糖運到全世界,如同今天的石油一樣。[5]

Today marks the 75th anniversary of "first light" for the the 200-inch Hale Telescope at Caltech's Palomar Observatory near San Diego. On January 26, 1949, renowned astronomer Edwin Hubble took the telescope's first picture, a celebratory moment in astronomy known as first light. The image, which shows a billowing nebula dotted with stars, marked the start of what was to be the world's largest effective optical telescope for the next 44 years.
