    Entropic Entanglement: Information Prison Break by Alexander Y. Yosifov, Lachezar G. Filipov

    Published 2017-01-01
    “…Also, we suggest that a possible interpretation of the Bekenstein-Hawking bound as entanglement entropy may yield a nonsingular dynamical horizon behavior described by black hole thermodynamics. Hence, by treating gravity as a field theory and considering its coupling to the matter fields in the Minkowski vacuum, we derive the conjectured fluctuations of the background geometry of a black hole.…”

    Nie jestem „przedszkolanką” ani „panią z I–III”. Nauczyciele o postrzeganiu siebie i społecznym odbiorze ich pracy by Agnieszka Nowak-Łojewska

    Published 2023-06-01
    “…The first trend indicates the pessimistic view of life of a modern teacher who finds it hard to accept the fact that they are not looked up to despite being conscious of gravity of their social role. The second, more optimistic trend is the one in which a teacher in addition to being aware of its social role perseveres in treating their profession as a vocation despite the lack of social respect and institutional support. …”
