LIMITS OF INFO. “By studying the mysterious properties of black holes, physicists have deduced absolute limits on how much information a region of space or a quantity of matter and energy can hold.” https://lnkd.in/draqjTW View in LinkedIn

SHANNON VS BOLTZMANN. “The two entropies have two salient differences, though. First, the thermodynamic entropy used by a chemist or a refrigeration engineer is expressed in units of energy divided by temperature, whereas the Shannon entropy used by a communications engineer is in bits, essentially dimensionless. That difference is merely a matter of convention.” https://lnkd.in/draqjTW View in LinkedIn

THE NOGGINS HAVE IT. “Remarkably, recent developments in theoretical physics answer some of these questions, and the answers might be important clues to the ultimate theory of reality.” https://lnkd.in/draqjTW View in LinkedIn

ENTROPY AND INFO. “Thermodynamic entropy and Shannon entropy are conceptually equivalent: the number of arrangements that are counted by Boltzmann entropy reflects the amount of Shannon information one would need to implement any particular arrangement.” https://lnkd.in/draqjTW View in LinkedIn

BIG QUESTION. “How much information does it take to describe a whole universe? Could that description fit in a computer's memory? Could we, as William Blake memorably penned, see a world in a grain of sand, or is that idea no more than poetic license?” https://lnkd.in/draqjTW View in LinkedIn

ORGANISMS AS AGENTS NOT OBJECTS. “Natural selection is not a consequence of how well the organism solves a set of fixed problems posed by the environment; on the contrary, the environment and the organisms actively co-determine each other.” (Lewontin 1978, in article by Denis M Walsh) https://lnkd.in/dchkheh View in LinkedIn

ASK THE RIGHT QUESTION FIRST. “Surprisingly, developments in gravitation physics in the past three decades have supplied some clear answers to what seem to be elusive questions.” https://lnkd.in/draqjTW View in LinkedIn

WORLD IN A GRAIN OF SAND. “Given the dizzying progress in miniaturization, one can playfully contemplate a day when quarks will serve to store information, one bit apiece perhaps. How much information would then fit into our one-centimeter cube? And how much if we harness superstrings or even deeper, yet undreamt of levels?” https://lnkd.in/draqjTW View in LinkedIn

THE INTERDEPENDENCE. “One cannot calculate the ultimate information capacity of a chunk of matter or, equivalently, its true thermodynamic entropy, without knowing the nature of the ultimate constituents of matter or of the deepest level of structure, which I shall refer to as level X.” https://lnkd.in/draqjTW View in LinkedIn
