• Neumann
• Von Neumann told him he should call it the "entropy" because nobody really knows what entropy is (indeed it does appear to be a loaded term ) and thus Shannon would have an advantage when debating his burgeoning field with pundits. (cisco.com)
• system
• Once you have given the box a good shake, you have pretty much maximized the entropy of the system. (tripod.com)
• Note that the collapse of the proto-solar system did not cause an increase in the entropy of some larger system as we would find in the classic refrigerator example. (tripod.com)
• The entropy inside the icebox is lower than that of the surrounding kitchen, but in running the motors of the fridge we have heated up the kitchen and the entropy of a larger system was increased in order to lower the entropy around our cold cuts and beer. (tripod.com)
• Entropy CAN in fact be reduced in a closed system, and this happens spontaneously according to the fluctuation theorem. (physicsforums.com)
• In either case, entropy of a closed system does not decrease. (physicsforums.com)
• For a many-body system in local equilibrium a stronger version of the second law applies which says that the entropy production at each spacetime point should be non-negative. (colorado.edu)

• In the meantime, Callisto reflects on the concept of entropy, on the possibility that the universe will ultimately suffer heat death and cease to act at all (the first sign of which is the constant thermometer reading outside his window), and on the possible implications of the laws of thermodynamics for social existence (this with some help from those investigators who had appropriated the term "entropy" from physics to information theory).

• biology
• Entropy and entropy generation play essential roles in our understanding of many diverse phenomena ranging from cosmology to biology. (springer.com)
• Erwin Schrodinger applied the concept of entropy to biology in 1944, concluding that hereditary carriers had to be small in size and permanent in form. (conservapedia.com)
• equally
• For example, the entropy of a coin flip with 2 equally likely outcomes is less than that of the roll of die with 6 equally likely outcomes. (cisco.com)
• If these values are equally probable, the entropy (in bits) is equal to this number. (wikipedia.org)
