可能除了理论物理学家之外,数学家则是需铅笔、纸,有时需图书馆以外而无须其他任何研究设备的唯一科学家了。大多数数学家至少有安定的家园。数学家的家庭,一般希望有稳定的收入,把他们的生活装扮得象科学院士世俗的富裕生活。数学家保罗·厄尔多斯,他充分利用数学家生涯赋予的自由散漫,数学研究完全占据他整整的一生。人们却称誉厄尔多斯是在生最伟大的数学家之一。这没有一点夸张,因为据说称誉厄尔多斯的在 It may be that, besides theoretical physicists, mathematicians are the only scientists who need pencil, paper, and sometimes libraries without any other research equipment. Most mathematicians have at least settled homes. Mathematicians’ families generally expect steady incomes to dress their lives like the secular rich life of academicians in science. The mathematician Paul Erdos, who takes full advantage of the freedom given to mathematicians, gives full play to his entire life. It is one of the greatest mathematicians in life that El Dos is credited with. This is not a little exaggerated, as Ellez is said to be credited with
