INCREASING ENTROPY. “The total entropy variation of the Kerr and Schwarzschild black holes has been calculated. The results show that the total entropy of two types of black hole increases with the advanced time. The evolution of the Schwarzschild black hole with Hawking radiation also satisfies the second law of thermodynamics.” https://lnkd.in/dYT-6ns View in LinkedIn

WIND SHAPES GENETICS. “We show that wind shapes three independent aspects of landscape genetics in plants with wind pollination or seed dispersal: populations linked by stronger winds are more genetically similar, populations linked by directionally imbalanced winds exhibit asymmetric gene flow ratios, and downwind populations have higher genetic diversity. The geography of both wind strength and wind direction play important roles in shaping large-scale genetic patterns across the world’s forests.” https://lnkd.in/dQsyc7U View in LinkedIn

ROOM FOR INFORMATION. “We have explained the black hole information paradox from the number of quantum states inside the black hole. Early literature reveals that the number of quantum states on the black hole surface is bounded. However, our calculation have shown that the number of quantum states of the scalar field inside the black hole is much more than that on the surface.” https://lnkd.in/dYT-6ns View in LinkedIn

SURFACE:VOLUME RATIO. “When Hawking radiation exists, the number of quantum states on the surface gradually decreases. On the contrary, the number of quantum states inside the black hole increases. Consequently, we propose that the information so-called lost in the process of black hole evaporation is stored in the black hole as the form of quantum states. Hence, the information has never been lost.” https://lnkd.in/dYT-6ns View in LinkedIn

OUTSTANDING LECTURES. “This is the written version of three lectures on complexity and black holes given at PiTP 2018 summer program entitled ”From Qubits to Spacetime.” The first lecture describes the meaning of quantum complexity, the analogy between entropy and complexity, and the second law of complexity.” (Leonard Susskind, Stanford Institute for Theoretical Physics and Department of Physics, Stanford University). https://lnkd.in/ds-Y-vp View in LinkedIn

BLACK HOLES AS BRAINS. “Given that black holes and human brains exhibit extraordinary memory storage capacities, it is natural to ask whether these systems share some very basic mechanism of the enhanced capacity of the information storage.” https://lnkd.in/dMWsyPJ View in LinkedIn

PHASE CHANGE. “The idea is that by allowing the excitatory synaptic connections among the set of neurons to be gravity‐like – in the sense of a negative interaction energy – the network gives rise to a critical state with an exponentially enhanced memory storage capacity.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=nn-sqzr1LtkAAAAA%3Axz_GSzZ1qHcoqtsAnyUFHP7LE4hzmCqVF57CqUh5T7pkS8T48kTAc_oyaUb3Ticpy78QnB1xd9Jk4mw View in LinkedIn

EXPONENTIAL JUMP. “This state is achieved due to the following effect. A high excitation level of some neurons – due to their negative synaptic connections with others – lowers to zero the excitation threshold energies for the latter neurons, thereby making is possible to store an exponentially large number of patterns within an infinitesimally narrow energy gap. Moreover, the patterns stored in such states can be redialed under an influence of arbitrarily soft external stimuli.” https://onlinelibrary.wiley.com/doi/full/10.1002/prop.201800007?casa_token=nn-sqzr1LtkAAAAA%3Axz_GSzZ1qHcoqtsAnyUFHP7LE4hzmCqVF57CqUh5T7pkS8T48kTAc_oyaUb3Ticpy78QnB1xd9Jk4mw View in LinkedIn

SCIENCE HATES CHANGE. “After considerable reluctance, the mathematical community were persuaded to accept non-Euclidean geometry as a branch of geometry, but it was considered to be merely of academic interest since the geometry of the physical world was Euclidean.” https://lnkd.in/dSq_i3g View in LinkedIn
