Contribution of Emile Durkeim stands out as the first "modern" sociologist. Society was a name for the network of relationships that caused the members of that society to behave in specific ways. Further, a primary objective of every society was to communicate to its members a sense of solidarity. Society is a much more concrete entity. Network of relationships can excercise forces on people in subtle ways. Define: holism systems have properties that do not exist at the level of individual elements of the system Jean Lamark French biologist who proposed that evolution occurred because animals had an "inner need" to change and that acquired characteristics were passed to offspring.

  • 18. the 2Nd & 3Rd Laws of Thermodynamics
    18. The 2nd & 3rd Laws of Thermodynamics Introduction and Summary The oldest statement of the 2nd Law comes from the German physicist and mathematician Rudolf Clausius. He said that "heat can flow spontaneously from a hot object to a cold object; heat does not flow spontaneously from a cold object to a hot object." (P.416 Giancoli and also http://en.wikipedia.org/wiki/Second_law_of _thermodynamics) At first glance, this appears to be a restatement of the 0th Law but it is in fact a little different. Heat can be made to flow from a cold object to a warm object--for example, in a refrigerator or with an air conditioner. However, this does not happen spontaneously--that is, by itself--since work must be done for this to happen. The 2nd Law is a little strange since it is a statement about something that does not happen. 2 18. The 2nd & 3rd Laws of Thermo dynamics Rev2.nb Another statement of the 2nd Law, made by the English physicist Lord Kelvin, is that a quantity of heat Q cannot be converted entirely into work W. 18. The 2nd & 3rd Laws of Thermo dynamics Rev2.nb 3 Some of the heat must leave the engine and be expelled into the environment as waste heat. Since efficiency equals the work done divided by the heat put in, the 2nd Law says a heat engine cannot be 100% efficient. It is perhaps surprising, that if you assume the Clausius statement of the 2nd Law is true, then you can prove that the Kelvin statement is also true and vice-versa.

Entropy is a concept with a complex history and has been the subject of diverse reconstructions and interpretations. This paper presents a brief review of the origin of the concept (Clausius and Boltzmann), a description of some influential textbooks (Planck, Fermi and Gibbs) and a comparative review on textbooks and how the concept of entropy is conceived and taught by university teachers. The results show that there is a great variety in the descriptions and meanings of entropy provided in textbooks, confusing students and teachers. A brief discussion focuses on new conceptual approaches to entropy. We conclude by suggesting how history can contribute to teachers and students’ awareness about changes in the meaning of entropy and their acceptance of a more relevant commitment in their understanding of physical concepts.

  • Theory of Electricity by Rudolf Clausius in the Development of Thermodynamics
    Eri Yagi and Rika Tadokoro Theory of Electricity by Rudolf Clausius in the Development of Thermodynamics Abstract Clausius’s four papers (1852-57) on the theory of electricity are analyzed by the help of our own database. These papers are classified by him under the mechanical theory of heat together with his papers on thermodynamics and gas theory. The first law and the essential part of the second law of thermodynamics were established in his first Abhandlung (1850). The first law is applied to these four papers on the theory of electricity, where heat, produced by electricity, is considered as the equivalent with the mechanical work. The essential part of the second law is applied to the 12th paper on thermoelectric current. The current between two different metals is treated by the similar method to heat flow. Here the temperature dependence is expressed as dt/C which is the maximum work of the infinitesimal Carnot cycle. 1. Introduction R. Clausius’s published papers, books (1847-85) and his manuscripts at the Library of the Deutsches Museum were studied,9-16 and the role of his papers on the theory of electricity was made clear. The so called “Clausius’s mechanical theory of heat” (die Mechanische Waermetheorie) consists of three fields, e.g., thermodynamics, the theory of electricity, and gas theory. Two volumes of his collected papers, compiled his 16 papers.1 Among these 16 papers, the 1st to the 9th papers (1850-65) are on thermodynamics, the 10th to the 13th papers (1852-7) on the theory of electricity, and the 14th to the 16th papers (1857-62) on gas theory.2 Clausius presented the first law of thermodynamics in his first paper on the mechanical theory of heat in 1850,2(I) in the differential form.

    Physics and Philosophy Issn: 1863-7388 2007 Id: 008 Article The Controversial Universe: A Historical Perspective on the Scientic Status of Cosmology Helge Kragh (Steno Institute, University of Aarhus, Denmark. E-mail: [email protected]) Abstract: The domain of cosmology is the universe, a singular concept, and basically for this reason cosmology is a science that diers from other sciences. For a long time there have been critical voices which argue that cosmology cannot be a proper science on par with, say, nuclear physics or hydrodynamics. This kind of critique goes a long way back in time, and I review it here in a historical perspective, focusing on the century from 1870 to 1970. I suggest that there are no good reasons to deny cosmology the status of a proper science. On the other hand, I also consider it natural, and a sign of health, that such foundational questions continue to be part of the cosmological discourse. Keywords: Cosmology, history of modern cosmology, science, universe, Kant 1 During the last fty years or so, cosmology has developed greatly and is today recognized to be a mature and fundamental part of the physical sciences. With the Nobel prizes in physics awarded in 1978 and 2006 to work related to big- bang cosmology it may seem pointless to argue that cosmology is not a proper science. After all, it is hard to imagine that Nobel laureates in physics should earn the prize for doing work that doesn't even qualify as science. It is generally recognized, often with a considerable measure of self-congratulation, that The discovery of the cosmic microwave background in the 1960s established the big bang theory and made cosmology into an empirical science, such as stated in an article in Scientic American from 1992 (Brush 1992, p.

  • Die Idee Des Humanen Rudolf Virchow Und Hermann Von Helmholtz
    Der Reichskanzler der Physik: Leben und Wirken von Hermann von Helmholtz Es ist Kaiser Wilhelm I., der im Jahre 1883 den 1821 in Potsdam gebo­ renen Hermann Helmholtz in den Adelsstand erhebt, kurz nachdem der als Mediziner ausgebildete, als Sinnesphysiologe erfolgreiche, als Philosoph beeindruckende, als Physiker überragende und sich in vie­ len populär gehaltenen Schrifen um die Vermittlung seines Wissens­ schatzes bemühende Universalgelehrte zusammen mit Industriellen und Freunden eine Denkschrif verfasst hat, in der vorgeschlagen wird, ein »Institut für die experimentelle Förderung der exakten Naturfor­ schung und Präzisionstechnik« zu gründen. Das Vorhaben kann mit Erfolg durchgeführt werden und hat die berühmte Physikalisch­Tech­ nische Reichsanstalt entstehen lassen, zu deren erstem Präsidenten der preußische Staat 1887 den verehrten Bildungsbürger und Kulturträger Hermann von Helmholtz beruf. Ihm wird dafür sogar ein exorbitan­ tes Salär zugebilligt, dessen Höhe Helmholtz selbst vorgeschlagen hat. Die Physikalisch-Technische Reichsanstalt (jetzt: Physikalisch-Technische Bun- desanstalt) wird 1887 auf maßgebliche Initiative von Werner von Siemens in Berlin gegründet. Hermann von Helmholtz ist ihr erster Präsident. 122 Er meint, dass ihm dies als »Reichskanzler der Physik«, wie er in An­ spielung auf Bismarck von seinen Kollegen respektvoll genannt wird, zustehe. Schließlich habe er eine Gelehrtenrepublik zu regieren wie der Reichskanzler seine Nation, und tatsächlich beklagt sich niemand über die Besoldung des Präsidenten. Man betrachtet sie wohl als angemessen angesichts des Arbeitspensums, das Helmholtz als Leiter der großange­ legten Institution zu bewältigen hat. Unter seiner Leitung führen Wis­ senschafler eine Fülle von Forschungsarbeiten durch, um den Einsatz von Elektrizität zu erproben oder zu einem besseren Verständnis von Wärme und Licht zu gelangen.

  • CLAUSIUS INEQUALITY and ENTROPY – with a Little History Thrown In
    CLAUSIUS INEQUALITY AND ENTROPY – with a little history thrown in. CARNOT PROPOSED THAT HEAT MUST ALWAYS BE WASTED IN ORDER FOR A HEAT ENGINE TO PRODUCE NET WORK, BUT HE DID NOT QUANTIFY HOW MUCH HEAT HAD TO BE WASTED. IN ~ 1850 RUDOLF CLAUSIUS CONFIRMED THE EXISTING THEORIES: 1. ENERGY IS CONSERVED (1ST LAW) WAS QUANTIFIED AS Q – W = ΔU 2. HEAT FLOWS NATURALLY FROM HOT TO COLD (NOT QUANTIFIED) AND ADDED AN IMPORTANT CONTRIBUTION: CLAUSIUS KNEW THAT SOME HEAT HAD TO BE REJECTED FROM A REVERSIBLE (CARNOT) HEAT ENGINE (QL), AS CARNOT PROPOSED, AND HE KNEW THAT ST QL = Wnet – QH (1 LAW) BUT NO PRINCIPLE FIXED THE ABSOLUTE AMOUNT OF REJECTED HEAT. CLAUSIUS THEN OBSERVED THAT FOR REVERSIBLE HEAT ENGINES, THE RATIO OF THE HEAT INPUT TO THE REJECTED HEAT WAS CONSISTENTLY EQUAL TO THE RATIO OF THE ABSOLUTE TEMPERATURES OF THE HIGH AND LOW TEMPERATURE RESERVOIRS: 1 Q T H = H (1) QL TL If and only if the temperature of the high (TH) and low (TL) temperature reservoirs are always expressed in degrees Kelvin. REARRANGING (1) FOR A REVERSIBLE HEAT ENGINE: Q Q H = L (2) TH TL CLAUSIUS THEN EXAMINED IRREVERSIBLE PROCESSES AND FOUND THAT THE RELATION (2) DID NOT HOLD. HE REASONED, FOR EXAMPLE, IF 10 JOULES 0F HEAT FLOW FROM A HOT OBJECT AT 350K INTO A COOL ROOM AT 300K, THEN THE HEAT TRANSFER TERM FOR HEAT LEAVING THE OBJECT AND HEAT TRANSFERRED INTO THE ROOM IS THE SAME AND Q Q 10 10 < or < (3) THLT 350 300 That is, for irreversible processes, the ratio of heat over absolute temperature increases in the direction of natural heat flow.
