我们在这个过程中得到的能量比质子携带的能量要大一些。可是多出来的能量很有限，方式也很无效率。如果谁想利用这种能源的话，他要知道他谈的能量如同月光。但在科学上来说这个问题很有趣，他让我们对原子有更多的认识。

In London, where Southampton Row passes Russell Square, across from the British Museum in Bloomsbury, Leo Szilárd waited irritably one gray Depression morning for the stoplight to change. A trace of rain had fallen during the night; Tuesday, September 12, 1933, dawned cool, humid and dull. Drizzling rain would begin again in early afternoon. When Szilárd told the story later he never mentioned his destination that morning. He may have had none; he often walked to think. In any case another destination intervened. The stoplight changed to green. Szilárd stepped off the curb. As he crossed the street time cracked open before him and he saw a way to the future, death into the world and all our woes, the shape of things to come.
