Where did Einstein say ‘The most incomprehensible thing abou

"The most incomprehensible thing about the world is that it is comprehensible." 是出自华仑泰写的爱恩斯坦自传 “Einstein:A Biography (1954) by Antonina Vallentin,p.24”.其实爱恩斯坦没有这样说过,在”Out of My Later Years (1956)“.他是这样写的 ”One may say the eternal mystery of the world is its comprehensibility."
