Kindi studied the substance, Motion, and time. These were the same problems that Einstein tried to solve. Al-Kindi started a series of experiments in physics and proved every claim scientific experiments. Kindi was convinced that the universe was finite. So, by following Kind, other Muslim scientists also accepted that motion and time are also limited. That is, he predicted that motion and time must be related to an event or thing and must begin and will end. Therefore, they can be measured. Although in Kindi's life, Instruments for measuring time and motion had not yet been invented. T skeems that Kindi had looked to the future to see when measuring instruments and clocks would be inkvented. His revolutionary ideology that scientists can determine the amount of most things in the wokrld, this theory had far-reaching effects on medicine. Optics: Optics was the part of physics in those days. Kindi was the first Muslim scientist in general who did research in this field. His special field of investigation was Geometrical Optics. He compiled his resekarch as a book under the name "Al-Basr" which is translated into Latin in the name of “De Aspectibus”. An European optics experts (Roger Bacon, Albert Magnus, Room of Giles) benefited from it for centuries. There were 24 chapters of Al-Basr, where Issues were discussed such as: Why do the rays of light come in a straight line? Effect o f vision without mirror, the process of vision in mirrors, the effect of distance and angle on vision., The original book in Arabic has been rare for centuries. In the foreword to the book, Kindi described “educational sciences" as mathematical science. Because according to him Geometry was the part of optics. In the book, in addition to his experiments in mathematics arguments were also presented. In this field of knowledge, Kundi's ideas provided scientific food to Muslim scientists (Ibn al-Haytham, Ibn Sina, Shirazi) and Europeans scientists. In fact, the promotion of landscape science in Europe was due to Kindi's book and Ibn al-Haytham's book Al-Manazer. It is a common thing that Kundi applied mathematical geometry to solve the problems of optics such as: Perspective, shadows, refraction, reflection, and burning mirrors, influence of distance and angle on the sight, optical illusions, rays travel in a straight line. Another of his works, Kitab al-Shu'a'at, was translated into Latin as “Radis Stellarum” that described the of Theory of Light. Everything in the world... emit rays in every direction, which fills the whole world. Rajar Bacon said Kindi was the Master of theology. Rather, he had used excerpts repeatedly in his book “Perspectiva”. The effect of Kandy's was huge on Italian scientist DaVinci. Until the seventeenth century, references of Kindi's book were given by every scientist in Europe. His book on optics "Fi Al-A'aat", also present in Patna, Afaq Khuda Bakhsh Library, City of India. Geography: His book on geography “Description of the Inhabited part of the Earth” has been translated into English. Italian Cardanus mentioned Kindi as one of the twelve great human beings of humanity. Musicology: Al-Kindi had a special interest in music. He was the first Muslim thinker who included music in the category of science. According to Kindi, music Is the name of harmony of different ends. Each head has a specific degree that depends on the number of vibrations. He was the first to invent a method of determining the number of vibrations. He Invented many musical instruments itself and classified them. Kindi treated many patients with music while applying in medicine. By observation and estimation, he proposed the idea that sound creates waves in the air. These waves hit the eardrum of our ears, causing it to vibrate in the air and produce sound. Centuries later, scientists proved that Al-kindi did this theory was right. Kindi said that the song was created by the combination of sound waves that are created in the air, of the head.
