In 1930 S. Ulam [I] showed that there is no such measure on w1,w2, or on any
cardinal1 which is the successor of some other cardinal. Ulam's proof was a
spectacular advance in that it did not rely on any of the geometric assumptions,
such as translation invariance, on which earlier proofs of the existence of non-measurable
sets had relied.

在1930年第乌拉姆[一]显示，有没有这样的措施对W1的，条西2 ，或在任何cardinal1这是继承的其他一些枢机主教。乌拉姆的证明是一个引人注目的进展，它不依赖任何的几何假设， 如平移不变，而先前的证据是否存在非可测量集依赖。
