集合论是19世纪末德国数学家格奥尔格·康托尔创造的。由于它深入到数学的每一个角落,所以成为一切数学分支的基础。英国哲学家、数学家罗素称赞康托尔的发现“或许是我们这个时代可引以为自豪的最伟大的事件”。 Set theory was created by German mathematician Georg Cantor in the late 19th century. As it goes deep into every corner of mathematics, it becomes the foundation of all mathematics branches. The British philosopher and mathematician Russell praised Cantor for his discovery that “perhaps the greatest event of our time to be proud of.”
