1021 – Ibn al-Haytham (Alhacen) pioneers the experimental scientific method and experimental physics in his Book of Optics, where he devises the first scientific experiments on optics, including the first use of the camera obscura to prove that light travels in straight lines and the first experimental proof that visual perception is caused ...
Iconoclasm (from Greek: εἰκών, eikṓn, 'figure, icon' + κλάω, kláō, 'to break') [i] is the social belief in the importance of the destruction of icons and other images or monuments, most frequently for religious or political reasons.
The earliest reference to the use of conoscopy (i.e., observation in convergent light with a polarization microscope with a Bertrand lens) for evaluation of the optical properties of liquid crystalline phases (i.e., orientation of the optical axes) is in 1911 when it was used by Charles-Victor Mauguin to investigate the alignment of nematic and ...
Beeldenstorm (pronounced [ˈbeːldə(n)ˌstɔr(ə)m]) in Dutch and Bildersturm [ˈbɪldɐˌʃtʊʁm] in German (roughly translatable from both languages as 'attack on the images or statues') are terms used for outbreaks of destruction of religious images that occurred in Europe in the 16th century, known in English as the Great Iconoclasm or ...
1957: Marvin Minsky, a professor at MIT, invents the confocal microscope, an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. This technology is a predecessor to today's widely used confocal laser scanning microscope.
Byzantine Iconoclasm, Chludov Psalter, 9th century. [10]Christian worship by the sixth century had developed a clear belief in the intercession of saints. This belief was also influenced by a concept of hierarchy of sanctity, with the Trinity at its pinnacle, followed by the Virgin Mary, referred to in Greek as the Theotokos ("birth-giver of God") or Meter Theou ("Mother of God"), the saints ...
Widespread destruction of images occurred during the Byzantine Iconoclasm of 726–842, although this did settle permanently the question of the appropriateness of images. Since then, icons have had a great continuity of style and subject, far greater than in the icons of the Western church .
Indeed, the definition of an experiment itself has changed in responses to changing norms and practices within particular fields of study. This article documents the history and development of experimental research from its origins in Galileo's study of gravity into the diversely applied method in use today.
