The most significant contributions to physics in the 4th-6th centuries CE were coming out of the Muslim world. Ibn al-Haytham, working during this time, is considered one of the fathers of modern optics. He suggested that light traveled in rays to the eye from various points of an object, an idea that differed from the way Ptolemy and his contemporaries saw the concept of light. Omar Khayyam created a very accurate solar calendar, considered to be more accurate than the Gregorian calendar used today. Other scholars made significant discoveries in trigonometry, which they used to measure distances from Mecca, which became helpful in aiding all Muslims in praying toward Mecca during daily prayer.
There were two planes at different times the same day, September 11, 2001. The planes did not fall on the towers. They were deliberatley flown into the towers by Muslim extremists and they were ordered to do so by Osama Bin Laden.
The "month" was originally intended to correspond to cycles of the moon's appearance, and some calendars in use in the 21st Century (Muslim, Hebrew, Chinese traditional) still synchronize their months with the moon. But the familiar Gregorian calendar used in western culture and commerce no longer synchs its months with the moon, so there's no natural phenomenon going on that can signal the passage of months, and you just have to look at the calendar.
Abu Ali al-Hasan ibn al-Hasan ibn al-Haytham (965 in Basra - c. 1040 in Cairo) was a prominent scientist and polymath from the 'Golden Age' of Muslim civilization. He is commonly referred to as Ibn al-Haytham, and sometimes as al-Basri, after his birthplace in the city of Basra. He is also known by his Latinized name of Alhzen or Alhacen. Ibn al-Haytham made significant contributions to the principles of optics, as well as to physics, astronomy, mathematics, ophthalmology, philosophy, visual perception, and to the scientific method. He was also nicknamed Ptolemaeus Secundus ("Ptolemy the Second") or simply "The Physicist" in medieval Europe. Ibn al-Haytham wrote insightful commentaries on works by Aristotle, Ptolemy, and the Greek mathematician Euclid.
