  • The best argument against it is the kind of microstate counting from string theory pioneered by Strominger and Vafa — they were always looking precisely at the extremal case, and found a non-zero entropy.

  • Chairman and Managing Director of Indian Bank T.M. Bhasin said that the bank had contributed immensely by initiating new dimensions in rural development such as microstate branches and Financial Liberty and Credit Counselling Centres.

  • CNN briefly flashed video of jubilant Palestinians celebrating amid the squalor of their microstate, but evidently thought better of running it more than once.

  • If it can be assumed that the probability of the microstate being in a given subregion of the macrostate is proportional to the phase space volume of the subregion, this gives Einstein's fluctuation formula.

    Information Processing and Thermodynamic Entropy Maroney, Owen 2009

  • The state space is divided up into a number of distinct regions and SB is defined in terms of the volume, W, of the region of state space to which the microstate belongs.

    Information Processing and Thermodynamic Entropy Maroney, Owen 2009

  • While an individual microstate can evolve from a high volume macrostate to a low volume macrostate, Liouville's Theorem guarantees that only a fraction of the microstates from the larger macrostate can end up in the smaller macrostate under a Hamiltonian evolution.

  • Before you invite some far-off microstate as your military ally, think about what the damnfools might do and to whom.

  • For example, it is often suggested that the Second Law derives from the fact that the initial microstate of the universe is as random as it can be, given its low-entropy macrostate.
