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.
1665 – Robert Hooke, using a microscope, observes cells. 1672 – Isaac Newton publishes the results of his Prism experiments, demonstrating the existence in white light of a mixture of distinct coloured rays. 1676 – Ole Rømer measures the speed of light for the first time.
1676 – Ole Rømer: Rømer's determination of the speed of light traveling from the moons of Jupiter. 1678 – Christiaan Huygens mathematical wave theory of light, published in his Treatise on Light; 1687 – Isaac Newton: Newton's laws of motion, and Newton's law of universal gravitation [8]
Although the thought experiment was formulated as an introduction to Heisenberg's uncertainty principle, one of the pillars of modern physics, it attacks the very premises under which it was constructed, thereby contributing to the development of an area of physics—namely, quantum mechanics—that redefined the terms under which the original thought experiment was conceived.
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.
Isaac Newton (1643–1727) investigated the refraction of light, demonstrating that a prism could decompose white light into a spectrum of colours, and that a lens and a second prism could recompose the multicoloured spectrum into white light. He also showed that the coloured light does not change its properties by separating out a coloured ...
As he worked to solve specific problems, Pasteur sometimes revised his ideas in the light of the results of his experiments, as when faced with the task of finding the cause of disease devastating the French silkworm industry in 1865. After a year of diligent work he correctly identified a culprit organism and gave practical advice for ...
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
