Entropy biology9/2/2023 ![]() ![]() These examples are programmatically compiled from various online sources to illustrate current usage of the word 'entropy.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. Sebastian Smee, Washington Post, After seven years in the Hammerskins, exhaustion and entropy were setting in. ![]() 2022 Succumbing to something closer to entropy than evolution, the watercolor starts to puddle and bruise. Ahmed Almheiri, Scientific American, 17 Aug. ![]() 2021 This is the island formula for the entanglement entropy of the Hawking radiation. Conor Feehly, Discover Magazine, 3 Nov. James Riordon, Scientific American, In short, the tendency for systems to move from low entropy to high entropy, the particular spacetime conditions of our solar system and the indeterminacy of the future combine to create our particular conception of time. James Riordon, Scientific American, The expansion allows the universe to smooth out, dissipating the entropy before collapsing again. Quanta Magazine, That flaw is entropy, which builds up as a universe bounces. 2022 If the entropy of the system decreases, the entropy of the environment must increase such that the sum of the two entropies can only increase or stay the same, but never decrease. Jennifer Ouellette, Ars Technica, 2 Dec. Note: The thing that is opposite to entropy is considered as Negentropy which means the system more organized or one can say that system is in more order, one of a good example for Negentropy is the solar system, where it is in more order.Recent Examples on the Web Jacob Bekenstein realized in 1974 that black holes also have entropy. So one can say that if there is a constant intake of energy in living organisms always cope up with entropy. For us, food is the energy to maintain any function, like locomotion, repair of cells, etc. Information and entropy are being used in biology in many different ways: for example, to study biological communication systems, the action. But when it comes to life, it is not an open system, where energy flows continuously in and out. If we consider the universe as an isolated system, however, the entropy is maximum. Isolated systems are always evolving spontaneously and provide thermodynamic equilibrium. According to the second-order of Thermodynamics, the entropy of a closed system will never decrease. In thermodynamics, the entropy is defined by a formula such as $S=\dfrac$ In living organisms, it mainly tells about the amount of energy that is available in the system to be utilized. Shannon’s discovery of the fundamental laws ofdatacompression andtransmission marks the birth. One can consider entropy as a state variable. Keywords: information, entropy, channel capacity, mutual information, AWGN 1 Preface Claud Shannon’s paper A mathematical theory of communication 2 published in July and October of 1948 is the Magna Carta of the information age. Living organisms, usually cope with entropy, because they take energy into the body in the form of food, whereas in the case of plants, in the form of photosynthesis, and at the same time, during this process, some energy is given out, or some energy may be wasted. Hint: Entropy is the variable, which is generally used to tell about of the disorder of the system, or it can also be defined as the amount of energy that is available in the system that to be used, greater the disorder of the system, we can say that entropy is more. ![]()
