He began studying black holes , quanta mechanics and the revolutionary ideas of elbert einstein .
他开始研究黑洞,量子力学和爱因斯坦的革新思想。
Of all his ideas , einstein considered his quantum explanation of the photoelectric effect --- postulating that light was composed of quanta , later called photons --- as the most revolutionary .
在他所有的观点中,爱因斯坦认为广电反应的量子解释光是由量子(后来被称为光子)是最具有革命意义的。
To reach the ground state , physicists had to cool their beams to nearly absolute zero . They also had to make the quanta as large as possible by making a beam stiffer to increase its frequency .
Professor du 's study demonstrates that a single photon , the fundamental quanta of light , also obeys the traffic law of the universe just like classical em ( electromagnetic ) waves .
