The most obvious example is that since the mid-20th century, many of the Nobel laureates in chemistry, biology, medicine, and even economics have had a background in physics. On the other hand, there has never been any scientist whose background is not in physics to have crossed over to win the Nobel for that field.
最明顯的例子就是，自 20 世紀中葉以來，無論是諾貝爾化學獎、生物、醫學獎，甚至經濟學獎的獲獎者，許多人都具有物理學背景，反觀之，卻從未有非物理專業出身的科學家，能撈過界來獲得諾貝爾物理學獎。
