Illustrated definition of Sum: The result of adding two or more numbers. i.e. Top Answer. What is the sum of your surroundings? ⟩ From a macroscopic perspective, in classical thermodynamics the entropy is interpreted as a state function of a thermodynamic system: that is, a property depending only on the current state of the system, independent of how that state came to be achieved. or you can say its the enviroment. It was originally devised by Claude Shannon in 1948 to study the size of information of a transmitted message. The definition of the information entropy is, however, quite general, and is expressed in terms of a discrete set of probabilities pi so that, In the case of transmitted messages, these probabilities were the probabilities that a particular message was actually transmitted, and the entropy of the message system was a measure of the average size of information of a message. k i {\displaystyle U=\left\langle E_{i}\right\rangle } Sequences and series are most useful when there is a formula for their terms. {\displaystyle T_{0}} Synonyms for sums include arithmetic, calculation, math, mathematics, computation, calculus, figuring, ciphering, reckoning and numbers. ) :95–112, In economics, Georgescu-Roegen's work has generated the term 'entropy pessimism'. The key is the idea of the surroundings. Meaning of surroundings. There is the idiomatic phrase whole package.Referring to the whole package when describing a person would be to refer to all of their attributes.. Any machine or process that converts heat to work and is claimed to produce an efficiency greater than the Carnot efficiency is not viable because it violates the second law of thermodynamics.  The fact that entropy is a function of state is one reason it is useful. Sum total definition is - a total arrived at through the counting of sums.  The author's estimate that human kind's technological capacity to store information grew from 2.6 (entropically compressed) exabytes in 1986 to 295 (entropically compressed) exabytes in 2007. d is path-independent. So this is the same thing as the mean of Y minus X which is equal to the mean of Y is going to be equal to the mean of Y minus the mean of X, minus the mean of X. Only a new order or agreement can change the payment schedule. Sum is a general operand. So that's this sum. Sum will total all the figures to give an annual total. {\displaystyle P_{0}} Q At low temperatures near absolute zero, heat capacities of solids quickly drop off to near zero, so the assumption of constant heat capacity does not apply. For example, the payments could be made monthly, quarterly, semi-annually, or annually. Flows of both heat ( where Boltzmann showed that this definition of entropy was equivalent to the thermodynamic entropy to within a constant factor—known as Boltzmann's constant. Q In German, he described it as Verwandlungsinhalt, in translation as a transformation-content, and thereby coined the term entropy from a Greek word for transformation. The two approaches form a consistent, unified view of the same phenomenon as expressed in the second law of thermodynamics, which has found universal applicability to physical processes. Look it up now! . 0 And this sum, you could view it as the average of the first and the last terms. The Carnot cycle and efficiency are useful because they define the upper bound of the possible work output and the efficiency of any classical thermodynamic system. The role of entropy in cosmology remains a controversial subject since the time of Ludwig Boltzmann. Nevertheless, some authors argue for dropping the word entropy for the H function of information theory and using Shannon's other term "uncertainty" instead..  It claims that non-equilibrium systems evolve such as to maximize its entropy production.. na_ma(yourData, k =2, weighting = "simple") In this case the algorithm would take the next 2 values in each direction. At such temperatures, the entropy approaches zero – due to the definition of temperature. Definition of lifeworld : the sum total of physical surroundings and everyday experiences that make up an individual's world Examples of lifeworld in a Sentence Recent Examples on the Web But as Carlyle, Rice and the family in A Quiet Place found out, creating a sound-free lifeworld … It’s not just the state of being on a soft couch that gives you Gemütlichkeit. ˙ For instance, an entropic argument has been proposed for explaining the preference of cave spiders in choosing a suitable area for laying their eggs.  Similar terms have been in use from early in the history of classical thermodynamics, and with the development of statistical thermodynamics and quantum theory, entropy changes have been described in terms of the mixing or "spreading" of the total energy of each constituent of a system over its particular quantized energy levels. P These equations also apply for expansion into a finite vacuum or a throttling process, where the temperature, internal energy and enthalpy for an ideal gas remain constant. It is a mathematical construct and has no easy physical analogy. The external objects, conditions, and circumstances that affect existence and development; the environment. {\displaystyle {\dot {W}}_{\text{S}}} L :545f, In Hermeneutics, Arianna Béatrice Fabbricatore has used the term entropy relying on the works of Umberto Eco, to identify and assess the loss of meaning between the verbal description of dance and the choreotext (the moving silk engaged by the dancer when he puts into action the choreographic writing) generated by inter-semiotic translation operations.. j Thus, when the "universe" of the room and ice water system has reached a temperature equilibrium, the entropy change from the initial state is at a maximum. Another word for surroundings. For a given thermodynamic system, the excess entropy is defined as the entropy minus that of an ideal gas at the same density and temperature, a quantity that is always negative because an ideal gas is maximally disordered.
