al-Hasan ibn al-Haytham

Abu Ali al-Hasan ibn al-Haytham (354 AH / 965 AD -430 AH / 1040 CE), the world is objective Muslim, made significant contributions in mathematics, optics, physics, anatomy, astronomy, engineering, medicine, ophthalmology, philosophy, psychology, visual perception and science in general his experiments conducted by the using the scientific method, and has published several books and scientific discoveries confirmed by modern science .
issue of Ibn al-Haytham."
Ibn al-Haytham moved to Cairo, where he lived most of his life, and there stated that his knowledge of mathematics can organize flooding of the Nile. Then ordered him to the Fatimid Caliph al-Hakim to the implementation of his ideas. However, Ibn al-Haytham quickly rammed the impossibility of implementing his ideas, and edit it, and claimed to fear for his life madness, Voghebr to stay at his home. Then, Ibn al-Haytham has devoted his life to his scientific work until his death.
Its Latin cover version of the book of Ibn al-Haytham landscape, which shows how Archimedes burnt the Roman ships attacking Syracuse when using a concave mirror.
Was Ibn al-Haytham made significant contributions in the field of optics and physics, and scientific experiments, as was his contributions to physics in general, and optics in particular, appreciated and the basis for the beginning of a new era in research optics theory and practice. focused his research in optics to study optical systems using mirrors especially on the mirrors and concave spherical and spherical aberration, as demonstrated by the ratio between the angle and the angle of refraction are not equal, and made a number of research on the forces of zoom lenses.

Landscape
Most famous work of Ibn al-Haytham his book with the seven volumes in the science of optics corresponding written between the years 401 AH / 1011 AD - 411 AH / 1021 CE. The book was translated into Latin at the hands of a cleric is not known at the end of the twelfth century or the beginning of the thirteenth century AD. The translation of this great impact on Western science
Theory of vision

Ibn al-Haytham proved that light travels in straight lines using the scientific experiments in his sights.
Prevailing theories about how the big vision in ancient times. First the theory of emission theory, endorsed by thinkers such as Euclid and Ptolemy, which assumes that the vision is based on the light rays emitted from the eye. The second theory theory of access endorsed by Aristotle and his followers, and assume that light entering the eye images of a physical. Ibn al-Haytham opposed the fact that the process of vision occurs by radiation emitted from the eye, or light entering the eye through the physical forms, and reasoned that the beam can not be based on the eyes and up to the distant stars in a moment once we open our eyes. Also opposed the belief that the eye may hurt if we look at the bright light brightness, and to develop instead the theory of a very successful explaining the process of vision as occurring as a result of exit light rays to the eye from every point in the object, which is demonstrated through experiments. as united optics engineering with the hypotheses of Aristotle's physics to form the basis of the optics of modern physics. proved to Ibn al-Haytham also that the light rays traveling in straight lines, also carried out various experiments on lenses, mirrors, refraction and reflection. and was also the first to be expelled light rays reflected and refracted in the heading for vertical and horizontal, which was a key development in optics engineering, proposed a model for the refraction of light lead to a conclusion similar to that led to the law of Snell, but Ibn al-Haytham did not develop his model enough to achieve that result.]
Scientific method
Neuroscience scientist said, "Rosanna Gurena" that "according to most historians, Ibn al-Haytham, the leading modern scientific method." Ibn al-Haytham has developed experimental methods to monitor the strict scientific experiments to verify the theoretical assumptions and extrapolation of the results. While some historians in the scientific experiments on the hypotheses of Ptolemy and interpretation of the trend toward innovation, making it does not have enough interest from historians.
There is a concept associated with Ibn al-Haytham visual research, based on the regular and systematic experimentation and the use of scientific method in scientific investigations. In addition, based on his experiences on the combination of classical physics and mathematics (geometry in particular) and use deductive approach to the conclusion in the field of scientific research. Confirmed this approach mathematical physicist at the experiences of most of the assumptions in his views, and supported his theories about vision and light and colors, as well as for his research in the science of mirrors and his study of the refraction of light, which benefited Kamaluddin Persian and developed in his book "The revision of the landscape."
The concept of Occam code also stated in the book scenes. For example, after explaining how the light arises from the luminous objects, and the emitted or reflected towards the eye, and said that "the traditional theory of emission of unnecessary and useless"
Visual research
Scenes in the book, Ibn al-Haytham was the first scientist to say that vision occurs in the brain rather than the eyes. He pointed out that personal experiences have an impact on what people see and how they see, and that the vision and imagination things relative.
In addition to the corresponding book, Ibn al-Haytham wrote many other treatises in the science of optics. His dissertation was a message in light of his book as a complete landscape, also in the treatise on the investigations about the properties of light and radiation scattered through various media transparent. By Ibn al-Haytham also many of the tests anatomy to the human eye and study the aberration optical, and making the first camera is dark and a pinhole camera, and also studied the properties of the rainbow and the density of the atmosphere, and discuss the phenomena revealed different (including the eclipse of the sun and the twilight and moonlight ). Ibn al-Haytham also studied refraction, mirrors and concave spherical lenses and magnifying.
