<u>Ibn al-Haytham:</u>
Ibn al-Haytham made huge advances in optics, science, and space science. His work on optics was described by a solid accentuation on painstakingly planned examinations to test speculations and theories.
Ibn al-Haytham is viewed as the dad of optics for his compelling The Book of Optics, which accurately clarified and demonstrated the cutting edge intromission hypothesis of visual observation, and for his analyses on optics, remembering tests for focal points, mirrors, refraction, reflection, and the scattering of light.

For instance, many point to the invasion of Germanic Tribes from the North as causing the end of Rome. In reality, by that time Rome had undergone a series of internal and external crises such as Persian attacks in the East, civil upheaval surrounding the rise of Christianity, and the abuse of power by emperors and their followers. In the end, it was a little bit of all of these problems that contributed to the fall of Rome.
