Herbert Walther
Herbert Walther (January 19, 1935 in Ludwigshafen/Rhein, Germany – July 22, 2006 in Munich) was a leader in the fields of quantum optics and laser physics. He was a founding director of the Max Planck Institute of Quantum Optics (MPQ) in Garching, Germany. He also was Chair of Physics at Ludwig Maximilian University of Munich. He is primarily known for his experimental work on cavity quantum electrodynamics (in the form of the micromaser) as well his groundbreaking work on the ion trap. At the time of his death he had over 600 publications and numerous awards from a number of prestigious physics and optics societies. In 1978 he won the Max Born Medal and Prize. In 1988 he received the Einstein Prize for Laser Science, in 1990 he received the Charles Hard Townes Award, in 1993 the Albert A. Michelson Medal from the Franklin Institute in Philadelphia and in 2003 the Frederic Ives Medal of The Optical Society Optica (formerly known as The Optical Society (OSA) and before th ...

Quantum Optics
Quantum optics is a branch of atomic, molecular, and optical physics dealing with how individual quanta of light, known as photons, interact with atoms and molecules. It includes the study of the particle-like properties of photons. Photons have been used to test many of the counter-intuitive predictions of quantum mechanics, such as entanglement and teleportation, and are a useful resource for quantum information processing. History Light propagating in a restricted volume of space has its energy and momentum quantized according to an integer number of particles known as photons. Quantum optics studies the nature and effects of light as quantized photons. The first major development leading to that understanding was the correct modeling of the blackbody radiation spectrum by Max Planck in 1899 under the hypothesis of light being emitted in discrete units of energy. The photoelectric effect was further evidence of this quantization as explained by Albert Einstein in a 1905 pa ...

Officers Crosses Of The Order Of Merit Of The Federal Republic Of Germany
An officer is a person who has a position of authority in a hierarchical organization. The term derives from Old French ''oficier'' "officer, official" (early 14c., Modern French ''officier''), from Medieval Latin ''officiarius'' "an officer," from Latin ''officium'' "a service, a duty" the late Latin from ''officiarius'', meaning "official." Examples Ceremonial and other contexts *Officer, and/or Grand Officer, are both a grade, class, or rank of within certain chivalric orders and orders of merit, e.g. Legion of Honour (France), Order of the Holy Sepulchre (Holy See), Order of the British Empire ( UK), Order of Leopold (Belgium) * Great Officer of State *Merchant marine officer or licensed mariner *Officer of arms *Officer in The Salvation Army, and other state decorations Corporations *Bank officer *Corporate officer, a corporate title **Chief executive officer (CEO) **Chief financial officer (CFO) **Chief operating officer (COO) *Executive officer Education *Chief academic ...

Optical Physicists
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...

Experimental Physicists
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e ...

Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many famous scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which in turn is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large format newspaper was released August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 device for buoying vessels by Abraham Lincoln, and the universal joint which now can be found in nearly every automobile manufactured. Current issues includ ...

Optical Society
Optica (formerly known as The Optical Society (OSA) and before that as the Optical Society of America) is a professional society of individuals and companies with an interest in optics and photonics. It publishes journals and organizes conferences and exhibitions. It currently has about 488,000 customers in 183 countries, including nearly 300 companies. History Optica was founded in 1916 as the "Optical Society of America", under the leadership of Perley G. Nutting, with 30 optical scientists and instrument makers based in Rochester, New York. It soon published its first journal of research results and established an annual meeting. The first local section was established in Rochester, New York, in 1916 and the '' Journal of the Optical Society of America'' was created in 1918. The first series of joint meetings with the American Physical Society was in 1918. In 2008 it changed its name to The Optical Society (OSA). In September 2021, the organization's name changed to Optica, ...
