Vor 4 Tagen · Entropy is the measure of the amount of missing information before reception. Often called Shannon entropy, it was originally devised by Claude Shannon in 1948 to study the size of information of a transmitted message.
Vor einem Tag · Entropy, introduced in Chap. 8, is generalized here for all fluids. The generalization operates on new concepts—ordinary and thermodynamic points. The corresponding proof is rather complex, and an analysis of adiabatic processes precedes it. Adiabats of an ideal gas, a Van der Waals fluid, and water are examined.
Vor 2 Tagen · Ultimately, high-entropy materials are at the forefront of materials chemistry and science as the unique compositional space that they occupy brings forward useful properties for applications. A key challenge lies in identifying appropriate high-entropy materials for a given application given the vast compositional space they offer.
Vor 4 Tagen · As heating occurs and the temperature rises, so does the entropy. At any subsequent temperature, the corresponding entropy depends upon how much energy was added to the material, and how much of that energy is stored within it. This illustrates a close connection between energy and entropy.
Vor einem Tag · More formally, the uncertainty principle is any of a variety of mathematical inequalities asserting a fundamental limit to the product of the accuracy of certain related pairs of measurements on a quantum system, such as position, x, and momentum, p. [1]
Vor 4 Tagen · In this constantly changing world, where entropy seems inevitable, each of us has the power to be an agent of order. Together, we can transform disorder into opportunities for growth and connection. Although entropy is a law of nature, our capacity to create order and harmony is infinite.
Vor einem Tag · Entanglement measures quantify the amount of entanglement in a (often viewed as a bipartite) quantum state. As aforementioned, entanglement entropy is the standard measure of entanglement for pure states (but no longer a measure of entanglement for mixed states).
