The Islamic intellectual crap is just like “Arabic numbers”.
It came from India, not Arabia or Persia. The West mistakenly gave credit to the last people who borrowed it.
Excerpt:
India’s heritage of solving problems is often overshadowed by centuries of colonialism and conquest. Outside Delhi I visited one of the oldest monuments to that history . . . pillar of iron alloy, smelted by Indian metallurgists with such skill that it has remained rustless for 1,500 years. (Photograph on page 533.)
These superb technicians were brethren of Indian thinkers who originated the concepts of zero and infinity and devised the inaccurately named Arabic numeral system, giving the science of mathematics to a world drenched in superstitious ignorance.
