THERMODYNAMICS IS QUANTUM. “We have repeatedly seen that quantum effects play a prominent role in the operation of the law: The GSL is at its roots a quantum law. We have also seen that the GSL is a statistical law.” (GSL = the generalized second law of thermodynamics). https://lnkd.in/dAr7QTt View in LinkedIn

SURFACE AREA. “In particular, the formal analogy between the second law of thermodynamics and Hawking’s area theorem, which states that black-hole surface area cannot decrease, motivated Bekenstein to conjecture that the required black-hole entropy is proportional to its surface area. https://lnkd.in/d3sfhP6 View in LinkedIn

ENTROPY AS INFORMATION. “It was while attempting to resolve this apparent paradox that Bekenstein came up with the bold idea to associate entropy with black holes – entropy as the measure of (missing) information about the black-hole internal state which is inaccessible to external observers.” https://lnkd.in/d3sfhP6 View in LinkedIn

FOOTNOTE. “The total entropy of a system either increases or remains constant in any process; it never decreases.” https://lnkd.in/d_98ekG View in LinkedIn

UNTHINKABLE VIOLATION. “In particular, to external observers it seems that the entropy of the visible universe decreases as the (entropy-bearing) object disappears into the black hole.” https://lnkd.in/d3sfhP6 View in LinkedIn

BRILLIANT. “In this gedanken experiment, the thermal entropy of the tea disappears behind the black-hole horizon. Hence, at first glance, it seems that the second law of thermodynamics, which states that entropy cannot decrease, is violated in this physical process.” https://lnkd.in/d3sfhP6 View in LinkedIn

TEA WITH MILK PLEASE. “The legend says that it all began with a cup of tea and two genius physicists, Professor John Archibald Wheeler and his young student Jacob David Bekenstein, who tried to figure out what happens to the second law of thermodynamics when the cup goes down a black hole.” https://lnkd.in/d3sfhP6 View in LinkedIn

Castle of Montfalcó Muralatt (near Lleida, Spain) was first mentioned in 1043 AD, and along with the nearby town is locked in Medieval time, giving an extraordinary sense of place. View in LinkedIn
