I think greatest man made invention is 'printing press', by Gutenberg, 15th century, Germany. bcoz of this it was possible to spread the knowledge so rapidly

 Best: Mathematics, the root of all sciences and inventions. Worst: Guns, the start of modern warfare and many crimes. Without math you would have no inventions, internet, or civilization. Guns lead to destruction and lost of lives. Those who thumb me down don't truly appreciate inventions and love war
