Icons of the 1920s: Albert Einstein is arguably the most famous and renowned scientist of modern times. Born in 1879 in what was then the German Reich, the physicist became world-famous for his theory of relativity. In 1922 he was awarded the Nobel Prize for his achievements, and above all for discovering the law of the photoelectric effect.
【愛因斯坦 139 歲冥誕】光電效應：愛因斯坦的諾貝爾
今天是愛因斯坦 139 歲冥誕，我會貼出一系列新舊文章紀念這位世紀科學巨人。
／／愛因斯坦對物理學的貢獻，絕對足夠好幾座諾貝爾物理獎。然而，愛因斯坦只在 1921 年獲頒過一次諾貝爾物理獎。很多人都以為他的得獎原因必為發現相對論。但原來，他獲獎的原因是解釋了一個我們日常會接觸到，但鮮少留意的現象：光電效應 (photoelectric effect)。
光電效應在高中物理課程裡應有所提及。簡單地說，光電效應就是太陽能電池的原理。光電效應的解釋，涉及一個古老問題：究竟光是什麼？／／
之前在英模班主題人物週和大家談到National Geographic頻道在播放「世紀天才」，記述愛因思坦(Albert Einstein)的一生，也預告中正紀念堂會有他的展覽。
現在，正式開展囉！
