Here are the 500 best academic universities in the world, according to Shanghai Jiao Tong University. The list starts: Harvard, Stanford, Cambridge, Berkeley, MIT, Cal Tech, Princeton, Oxford, Columbia, Chicago.
Only 35 countries have at least one university among the 500 (more exactly 502) best.
While Israel (population around 6 millions or 0.1% of mankind) has 7 of these, all the Islamic countries together (maybe 1/5 of mankind) have not a single one.
