Extractions: Born in Iraq as Abu Ali Hasan Ibn al-Haitham, the great Arab physicist is more often known by the Latinized version of his first name, Alhazen. Although he was to eventually become a profound intellectual specializing in mathematics and optics, Alhazen's early education was geared towards religion and prepared him for a career as a minister. However, apparently unhappy in his religious pursuits, Alhazen later decided to devote himself to the study of science and became particularly intrigued by Aristotle. Many details of Alhazen's life have been lost over time and the stories that remain are often contradictory depending on the historian relating them. Nevertheless, it is generally held that Alhazen went to Egypt at some point in his life with a scheme to control the waters of the Nile. Invited to engineer the plan by al-Hakim, who was to become known as the Mad Caliph, Alhazen realized the impossibility of the feat. However, although he failed, al-Hakim rewarded him with an official government post, a gift that was not to be envied. As al-Hakim's behavior became increasingly erratic, Alhazen is believed to have feared for his life, feigning madness in order to be relieved of his position. Consequently, he was largely confined to his house until al-Hakim's death in 1021. Such a situation provided him with large amounts of free time with which he could conduct experiments and write, but he may have also been busy copying manuscripts in order to support himself.

Home From the earliest days in Alexandria (circa 300 BC) when Euclid described the laws of reflection in Optica , the science of optics has fascinated and challenged society's most brilliant minds. The earliest pioneers in optics reached for the stars with difficulty as they developed crude lenses and mirrors for their telescopes while other investigators focused on the hidden microscopic world through aberration-plagued compound optical systems that hampered early microscopes. Today, millions of the optically-challenged need be thankful to these pioneers for the eyeglasses, contact lenses, and other advances that have evolved from innovations dating back as early as 1303 when Bernard of Gordon, a French physician, wrote about the use of spectacles as a way of correcting long-sightedness (hypermetropia). From the earliest compound microscopes, enabling anatomists to describe the properties of blood cells, to the modern electron and scanning laser confocal microscopes and NASA's Hubble space telescope, the science of optics has helped us understand the world around us, our bodies, and the diseases we face in our daily lives. Whether it is Polaroid instant photos, sunglasses, disposable contact lenses, the ubiquitous television, videos, or the more recent compact discs, fiber optics communications, and digital cameras, we all reap the harvest of seeds planted by pioneers in the optical sciences. Tribute is paid to these heroes through brief biographies that acknowledge their tremendous accomplishments and how they have affected our civilization.

Extractions: Nga DR. A. Zahur (Zahoor) Ebu Ali Hasan Ibn El Haitham, i njohur në perëndim me emrin Alhazen, konsiderohet si babai i optikës moderne. El - Haithan ishte një nga shkencëtarët më të shquar të kohës dhe kontributet e tij në optikë dhe në metodat shkencore janë të pakrahasueshme. Ka lindur më 965 në Basra (Iraku i sotëm) ku dhe i mori mësimet e para. Ai studioi gjthashtu edhe në Bagdad si dhe udhëtoi në Egjypt dhe Spanjë. Pjesën më të madhe të jetës së tij e kaloi në Spanjë ku dhe bëri hulumtime në optikë, matematikë, fizikë, mjekësi si dhe në zhvillimin e metodave shkencore. El-Haithami bëri eksperimente në përhapjen e dritës si dhe ngjyrat, iluzionet optike dhe refleksionin. Ekzaminoi thyerjen e rrezeve të dritës përmes mjetit transparent (ajrit dhe ujit) dhe zbuloi kështu ligjet e thyerjes së dritës. Gjithashtu ai bëri eksperimentet e para në shpërndarjen e dritës në ngjyrat e saj përbërëse. Në detajimin e eksperimentit të tij me segmentet sferike (enë qelqi të mbushtura me ujë), iu afrua shumë zbulimit të teorisë së lenteve zmadhuese e cila u zbulua 3 shekuj më pas në Itali. Ligji i sinusit do të merrte edhe tre shekuj të tjerë për t`u propozuar nga Snell dhe Dekart. Libri i tij "Kitab el-Manazir" i cili është përkthyer në Latinisht në epokën e mesjetës ka të bëjë me ngjyrat e muzgut. Gjerësisht trajton teoritë e fenomeneve të ndryshme fizike si : ylberi, hijet, eklipset, dhe spekulon rreth natyrës fizike të dritës. Roxher Bakon (shekulli 13), Polo Vitelio si dhe studjuesit e tjerë perëndimor të kohës së mesjetës që u morën me studimin e optikës, kryesisht u bazuan në "Opticae Thesaurous" të El-Haithamit. Vepra e tij gjithashtu influencoi Leonardo Da Vinçin dhe Johan Kepler.

Extractions: Alhazen (Abu Ali Hasan Ibn al-Haitham) : 965 - 1039 Alhazen , Arabic (Abu Ali Hasan Ibn al-Haitham) (b. c.965, Basra, Iraq d. 1039, Cairo), mathematician and physicist who made the first significant contributions to optical theory since the time of Ptolemy (flourished 2nd century). In his treatise on optics, translated into Latin in 1270 as Opticae thesaurus Alhazeni libri vii , Alhazen published theories on refraction, reflection, binocular vision, focussing with lenses, the rainbow, parabolic and spherical mirrors, spherical aberration, atmospheric refraction, and the apparent increase in size of planetary bodies near the Earth's horizon. He was first to give an accurate account of vision, correctly stating that light comes from the object seen to the eye. Source: Britannica Online The ancient Greek studies of mathematics, philosophy, the arts and science would have been lost to us forever if the Arabs had not preserved and collected this legacy for all. In addition, through their annotations and studies they added to our knowledge. One of the most famous of these Arab scholars was Alhazen (Abu Ali Hasan Ibn al-Haitham). His studies included contributions to physics, especially optics and mathematics.

Extractions: ABU ALI HASAN IBN AL-HAITHAM (ALHAZEN) (965 - 1040 AD) Al-Haitham, known in the West as Alhazen, is considered as the father of modern optics. Ibn al-Haitham was born in 965 C.E. in Basrah (present Iraq), and received his education in Basrah and Baghdad. He traveled to Egypt and Spain. He spent most of his life in Spain, where conducted research in optics, mathematics, physics, medicine and development of scientific methods. Al-Haitham conducted experiments on the propagation of light and colors, optic illusions and reflections. He examined the refraction of light rays through transparent medium (air, water) and documented the laws of refraction. He also carried out the first experiments on the dispersion of light into colors. In detailing his experiment with spherical segments (glass vessels filled with water), he came very close to discovering the theory of magnifying lenses which was developed in Italy three centuries later. It took another three centuries before the law of sines was proposed by Snell and Descartes. His book Kitab-al-Manazir was translated into Latin in the Middle Ages, as also his book dealing with the colors of sunset. He dealt at length with the theory of various physical phenomena such as the rainbow, shadows, eclipses, and speculated on the physical nature of light. Roger Bacon (thirteenth century), Pole Witelo (Vitellio) and all Medieval Western writers on Optics base their optical work primarily on Al-Haitham's 'Opticae Thesaurus.' His work also influenced Leonardo da Vinci and Johann Kepler. His approach to optics generated fresh ideas and resulted in great progress in experimental methods.
