For example: the photoelectric effect. This was a puzzle in the early 1900s. When light hits a metal, like zinc, electrons fly off. This can happen only if light comes in little packets concentrated enough to knock an electron loose. A spread-out wave wouldn't do the photoelectric trick.
例如:光电效应。这在20世纪初期的一道难题。当光照射到金属(如锌)上时,电子飞速飞离电子表面,这种现象只有当光的粒子集聚的程度足以把电子击撞松动的时候才会发生。漫延波不会产生光电效应。

The solution seems simple--light is particulate. Indeed, this is the solution Einstein proposed in 1905 and won the Nobel Prize for in 1921. Other physicists like Max Planck (working on a related problem: blackbody radiation), more senior and experienced than Einstein, were closing in on the answer, but Einstein got there first. Why?
答案似乎很简单——光是粒子。事实上,这是爱因斯坦1905年提出的解答,并因此于1921年获得诺贝尔奖。其他物理学家们,比如比爱因斯坦资历更深、经验更丰富的麦克斯普兰克(从事研究相关的问题:黑体辐射),其研究正接近该问题的答案,但爱因斯坦捷足先登。为什么?

In retrospect, Maxwell was right. Light is a wave. But Einstein was right, too. Light is a particle. This bizarre duality baffles Physics 101 students today just as it baffled Einstein in 1905. How can light be both? Einstein had no idea.
回想起来,麦克斯威尔是正确的。光是一种波。但爱因斯坦也是对的。光是粒子。这种异乎寻常的二象性使今天选修无力101课程的同学们感到困惑,就像在1905年使爱因斯坦感到困惑一样。光怎么可能既是波又是粒子呢?爱因斯坦无法理解。

That didn't slow him down. Disdaining caution, Einstein adopted the intuitive leap as a basic tool. "I believe in intuition and inspiration," he wrote in 1931. "At times I feel certain I am right while not knowing the reason."
困惑并没有使爱因斯坦放慢探究的脚步。爱因斯坦不屑谨小慎微,他采用直觉跳跃思维作为基本工具。“我相信直觉和灵感,”他在1931年写道。“有时尽管不知道原因,但是我肯定我是对的。

Einstein's parents sometimes took Albert to parties. No babysitter was required: Albert sat on the couch, totally absorbed, quietly doing math problems while others danced around him. Pencil and paper were Albert's GameBoy!
爱因斯坦的父母有时会带儿子参加聚会。她们不常请人看孩子:当其他人在他周围跳舞时,阿尔伯特坐在沙发上,全神贯注,静静地做数学题。笔和纸是阿尔伯特的玩具!

Later in life, it should be remembered, he struggled mightily to produce a unified field theory, combining gravity with other forces of nature. He failed. Einstein's brainpower was not limitless.
应该记住的是,爱因斯坦在晚年竭尽全力想象提出统一场论,把万有引力和自然界中其他的力结合起来。但他失败了。爱因斯坦的智力不是无限的。

Neither was Einstein's brain. It was removed without permission by Dr. Thomas Harvey in 1955 when Einstein died. He probably expected to find something extraordinary:Einstein's mother Pauline had famously worried that baby Einstein's head was lopsided. (Einstein's grandmother had a different concern: "Much too fat!") But Einstein's brain looked much like any other, gray, crinkly, and, if anything, a trifle smaller than average.
爱因斯坦的大脑也是如此。他1955年去世的时候,托马斯哈维医生在未经许可的情况下解剖了他的大脑。也许他期盼发现一些惊人的东西。但是爱因斯坦
