庞加莱与居里致苏黎世联邦技术学院书（给爱因斯坦的推荐信）
Henri Poincare and Marie Curie to the Federal Institute of Technology at Zurich
Herr Einstein is one of the most original minds that we have met. In spite of his youth he already occupies a very honorable position among the foremost savants of his time. What we marvel at him, above all, is the ease with which he adjusts himself to new conceptions and draws all possible deductions from them. He does not cling to classical principles, but sees all conceivable possibilities when he is confronted with a physical problem. In his mind this becomes transformed into an anticipation of new phenomena that may some day be verified in actual experiences…The future will give more and more proofs of the merits of Herr Einstein, and the University that succeeds in attaching him to itself may be certain that will derive honor from its connection with the young master.
Herri Poincare
Marie Curie
中文译文：
爱因斯坦先生是我们有生以来所认识的人中间最具有独创性的才子之一。尽管他年纪尚轻，却已经在当代最杰出的学者之间有一席显荣地位。尤其使我们惊叹的是他非常容易适应新的概念，并从中得出各种个能的推论。当他遇到一个物理学问题时，他从不拘泥于权威性的原理，却可以想到一切可以想象的可能性。这一点在他脑中得到融会贯通，使他预见到许多有朝一日终将在实际生活中获得证实的新现象….爱因斯坦先生的才华将来一定能得到更多的证明。凡是能罗致这位青年学者的大学，必将获得附骥之荣。
