Microscope
A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using a microscope. Microscopic means being invisible to the eye unless aided by a microscope. There are many types of microscopes, and they may be grouped in different ways. One way is to describe the method an instrument uses to interact with a sample and produce images, either by sending a beam of light or electrons through a sample in its optical path, by detecting photon emissions from a sample, or by scanning across and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses lenses to refract visible light that passed through a thinly sectioned sample to produce an observable image. Other major types of microscopes are the fluorescence microscope, electron microscope (both the transmi ...

Museums Established In 1964
A museum ( ; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists, to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 countries ...

Scanning Tunneling Microscope
A scanning tunneling microscope (STM) is a type of microscope used for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer, then at IBM Zürich, the Nobel Prize in Physics in 1986. STM senses the surface by using an extremely sharp conducting tip that can distinguish features smaller than 0.1  nm with a 0.01 nm (10 pm) depth resolution. This means that individual atoms can routinely be imaged and manipulated. Most microscopes are built for use in ultra-high vacuum at temperatures approaching zero kelvin, but variants exist for studies in air, water and other environments, and for temperatures over 1000 °C. STM is based on the concept of quantum tunneling. When the tip is brought very near to the surface to be examined, a bias voltage applied between the two allows electrons to tunnel through the vacuum separating them. The resulting ''tunneling current'' is a function of the tip position, applied ...

Camera Lucida
A ''camera lucida'' is an optical device used as a drawing aid by artists and microscopists. The ''camera lucida'' performs an optical superimposition of the subject being viewed upon the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure. This allows the artist to duplicate key points of the scene on the drawing surface, thus aiding in the accurate rendering of perspective. History The ''camera lucida'' was patented in 1806 by the English chemist William Hyde Wollaston. The basic optics were described 200 years earlier by the German astronomer Johannes Kepler in his ''Dioptrice'' (1611), but there is no evidence he or his contemporaries constructed a working ''camera lucida''. By the 19th century, Kepler's description had fallen into oblivion, so Wollaston's claim was never challenged. The term "''camera lucida''" (Latin "well-lit room" as opposed to ''camera obscura'' "dark room") i ...

Jean-Daniel Colladon
Jean-Daniel Colladon (15 December 1802, Geneva – 30 June 1893) was a Swiss physicist. Colladon studied law but then worked in the laboratories of Ampère and Fourier. He received an Académie des Sciences award with his friend Charles Sturm for their measurement of the speed of sound and the breaking up of water jets. Stymied by the lack of a sight of the water jet provided to the audience, he used a tube to collect and pipe sunlight to the lecture table. The light was trapped by the total internal reflection of the tube until the water jet, upon which edge the light incidented at a glancing angle, broke up and carried the light in a curved flow. Colladon reported this experiment to a wider audience in the '' Comptes rendus'', the French Academy of Sciences' journal, in 1842. His experiments formed one of the core principles of modern-day optical fiber, alongside those of: * Auguste Arthur de la Rive — who demonstrated Colladon's experiment using electric arc light&nbs ...

François Jules Pictet De La Rive
François Jules Pictet-De la Rive (27 September 180915 March 1872) was a Swiss zoologist and palaeontologist. Biography He was born in Geneva. He graduated B. Sc. at Geneva in 1829, and pursued his studies for a short time at Paris, where under the influence of Georges Cuvier, de Blainville and others, he worked at natural history and comparative anatomy. On his return to Geneva in 1830 he assisted A. P. de Candolle by giving demonstrations in comparative anatomy. Five years later, when de Candolle retired, Pictet was appointed professor of zoology and comparative anatomy. Endnotes: *Obituary by W. S. Dallas, ''Quart. Journ. Geol. Soc.'' (1873), vol. xxix. In 1846 his duties were restricted to certain branches of zoology, including geology and palaeontology, and these he continued to teach until 1859, when he retired to devote his energies to the museum of natural history and to special palaeontological work. He was rector of the Academy from 1847 to 1850, and again from 1866 ...

Marc-Auguste Pictet
Marc-Auguste Pictet (; 23 July 1752 – 19 April 1825) was a Swiss scientific journalist and experimental natural philosopher. Pictet's main contribution to learning was his editing of the scientific section of the ''Bibliothèque Britannique'' (1796-1815), a publication devoted to the diffusion on the Continent of knowledge and arts produced in Great Britain. His own scientific research focused on the fields of physical science, especially calorimetry, but also astronomy, geology, meteorology and technology, especially chronometry and the manufacture of fine earthenware. Life He was born in Geneva, Republic of Geneva on 23 July 1752, the son of Charles Pictet, a military officer serving in the mercenary troops of the Netherlands, and his wife, Marie Dunant. Marc-Auguste studied natural philosophy and law at the Academy of Geneva and qualified as a lawyer in 1774. After one year in England (1775–76), he became assistant to Jacques-André Mallet at the Geneva Observato ...

Thermometer
A thermometer is a device that temperature measurement, measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, in meteorology, in medicine, and in scientific research. History While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. Internationally agreed temperature scales are designed to ...
