	Max Planck - Wikipedia, the free encyclopedia
		Planck was musically gifted: he took voice lessons in addition to playing the piano, organ and cello, and composing songs and operas.
		His famous Planck fl-body radiation law described the experimentally observed fl-body spectrum very well; it was first proposed in a meeting of the DPG on October 19, 1900 and published in 1901.
		Planck and Nernst, in order to clarify the increasing number of contradictions, organised the First Solvay Conference (Brussels 1911); at this meeting Einstein was finally able to convince Planck.

	Max Planck - Wikipedia, the free encyclopedia
		The discovery of Planck's constant enabled him to define a new universal set of physical units (such as the Planck length and the Planck mass), all based on fundamental physical constants.
		In 1938, Planck celebrated his 80th birthday; the DPG held an official celebration, during which the Max-Planck medal (founded as the highest medal by the DPG in 1928) was awarded to French physicist Louis de Broglie - one year before the outbreak of a new war between France and Germany.
		of 1946, Planck was succeded as president of the KWG by Otto Hahn.

		Planck's son Erwin was executed on July 20, 1944, for treason in connection with an attempted assassination of Hitler.

		Planck's son Erwin was executed in January, 1945, for treason in connection with an attempted assassination of Hitler.
		In 1894 Planck turned his attention to the problem of fl-body radiation, a problem that Kirchhoff formulated in 1859: How does the intensity of the electromagnetic radiation emitted by a fl-body (a perfect absorber, also known as a cavity radiator) depend on the frequency of the radiation and the temperature of the body?
		Planck interpolated between both laws using an assumption about the entropy, which led to the famous Planck fl-body radiation law.

	Biography of Max Planck
		Planck entered the University of Munich in the fall of 1874 and transferred to the University of Berlin in 1877 where his intellectual capacities were brought to a focus as the result of his independent study of Rudolf Clausius' writings on thermodynamics.
		Planck became permanent secretary of the mathematics and physics sections of the Prussian Academy of Sciences in 1912 and held that position until 1938.
		Planck's oldest son, Karl, was killed in action in 1916, his daughter Margarete died in childbirth in 1917, and another daughter, Emma also died in childbirth in 1919.

		Planck was able to combine these two radiation laws, arriving at a formula for the observed energy of the radiation at any given frequency and temperature.
		Planck's constant, a fundamental constant (symbol h), is the energy of one quantum of electromagnetic radiation divided by the frequency of its radiation.

		Planck was born in Kiel on April 23, 1858, and educated at the universities of Munich and Berlin.
		Planck's law states that the energy of each quantum is equal to the frequency of the radiation multiplied by the universal constant.
		Planck's discoveries, which were later verified by other scientists, were the basis of an entirely new field of physics, known as quantum mechanics, and provided a foundation for research in such fields as atomic energy.

		Max Planck was the originator of quantum theory, one of the cornerstones of twentieth century physics.
		Planck was well versed in thermodynamics and, stimulated by the work of Kirchhoff and Helmholtz, began in the mid-1890s theoretical investigations the radiation emitted by a fl body.
		Using mainly thermodynamic methods Planck was able to derive a function of temperature and frequency that agreed with the observed fl-body spectrum at all frequencies, and was also consistent with Josef Stefan's discovery that the total energy emitted by a fl body was proportional to the fourth power of its absolute temperature.

		Max Karl Ernst Ludwig Planck was born on April 23, 1858, in Kiel, Germany, the sixth child of a distinguished jurist and professor of law at the University of Kiel.
		Planck was particularly attracted to the formula found in 1896 by his colleague Wilhelm Wien at the Physikalisch-Technische Reichsanstalt (PTR) in Berlin-Charlottenburg, and he subsequently made a series of attempts to derive "Wien's law" on the basis of the second law of thermodynamics.
		Planck became permanent secretary of the mathematics and physics sections of the Prussian Academy of Sciences in 1912 and held that position until 1938; he was also president of the Kaiser Wilhelm Society (now the Max Planck Society) from 1930 to 1937.

		Born in 1858 as the son of a professor of jurisprudence, Planck was appointed professor of physics at the University of Berlin in 1889.
		Planck's thoughts centred on the concept of entropy and how to understand "irreversibility" on the basis of the absolute validity of the entropy law - the version of the second law of thermodynamics formulated in terms of the entropy concept.
		Planck did not emphasize the discrete nature of energy processes and was unconcerned with the detailed behaviour of his abstract oscillators.

	Planck's Hypothesis (Site not responding. Last check: 2007-11-07)
		Planck, who was a colleague of Wien's when he was carrying out this work, later, in 1900, based quantum theory on the fact that Wien's law, while valid at high frequencies, broke down completely at low frequencies.
		Planck himself in [7] explains how despite having invented quantum theory he did not understand it himself at first:- I tried immediately to weld the elementary quantum of action somehow in the framework of classical theory.
		Planck was also the first to succeed in getting, by means of the said relation, a highly accurate value for the number in question, the so-called Avogadro constant.

		Planck, a conservative man, was not trying to revolutionize physics at all, just to explain the particular phenomenon he was studying.
		In fact, when people refer to "classical physics" today, they mean "before Planck." He didn't fully appreciate the revolution he had started, but in the years that followed, scientists such as Albert Einstein, Niels Bohr, and Werner Heisenberg shaped modern physics by applying his elegantly simple, catalytic new idea.
		Planck was an extremely successful physicist, receiving the Nobel Prize in 1919, but his personal life was marked by tragedy.

		Planck even decided to study physics after he went to the University of Munich and was told that the studies of physics were practically complete with little work left.
		Planck said, "The outside world is something independent from man, something absolute, and the quest for the laws which apply to this absolute appeared to me as the most sublime scientific pursuit in life." (O'Conner, 1) This did not mean he dropped everything else.
		Planck also directed a choral singing group of neighborhood children, including his own, along with friends, although at first his musical ear was almost too good to enjoy it (Heilbron, 34).

		Planck is designed to 'see' the microwaves and, in practice, it will detect them by measuring temperature.
		As a consequence, the Planck detectors will have to be highly sensitive and will have to work at temperatures very close to the absolute zero, otherwise their own emission of heat will spoil the measurements.
