I read two statements about the Gaon recently:
1. "If the Gaon says that he could bring down kol galgal hachamah on this table and show it to Aristo - do we have a safek that what Chazal HaKedoshim said is emes?" Rav Uren Reich Rosh haYeshiva of Yeshiva of Woodlake Village in Lakewood
2. Baruch Schick, who published several works on mathematics and astronomy, wrote in his introduction to his translation of Euclid (Amsterdam, 1780) that he had heard the Gaon state that "in proportion to a man's ignorance of the other sciences, he will be ignorant of one hundred measures of the science of the Torah."
