While i was still in primary school, i knew i wanted to become a scientist, but as mathematics was taught, it did not attract me especially. i was very interested, on the other hand, in physics and biology and i read popular scientific books. but when i reached the ninth grade i began studying geometry and my eyes opened to that beauty - a system of demonstrations and theorems based on a very small number of axioms which impressed me and captivated me. on the other hand laboratories were not to my taste and vice versa. so, by the age of 15, i knew my desire was to be a mathematician?
