Speaker: Robert Wald (Chicago University, USA)ICTP School on Geometry and Gravity | (smr 3311)2019_07_15-14_15-smr3311.mp4 In the right panel, the red curve corresponds to the thermal small black phase while the purple curve is associated with the large phase and the black dashed line corresponds to the global minimum of F i.e. But a mathematical black hole, the basis of black hole thermodynamics, is not the material from the star that's collapsed. Sadly, a former tutor in JPU200Y was completely correct when he proposed the following multiple choice question for a test: Eddie Gonzales Jr. - MessageToEagle.com - In 1969, English physicist Roger Penrose discovered a property which would later allow for a long-awaited link between thermodynamics, and the far stranger mechanics of black holes. The discovery in the early 1970s that black holes radiate as black bodies has radically affected our understanding of general relativity, and offered us some early hints about the nature of quantum gravity. HISTORY OF BLACK HOLES • • • • • • Geologist John Mitchell put forward the idea of a body so massive that even light could not escape. S = kc 3 4ℏG A. The Bekenstein-Hawking entropy or black hole entropy is the amount of entropy that must be assigned to a black hole in order for it to comply with the laws of thermodynamics as they are interpreted by observers external to that black hole.This is particularly true for the first and second laws. Black holes, predicted by Albert Einstein's general theory of relativity more than a century ago, have long intrigued scientists and the public with their bizarre and fantastical properties. Including black holes in the scheme of thermodynamics has disclosed a deep‐seated connection between gravitation, heat and the quantum that may lead us to a synthesis of the corresponding branches of physics. The main reference, guideline, and motivation behind these lectures is the lucid and elegant book by Susskind and Lindesay .

The current observation of black hole mergers and neutron stars coming together by Thorne's Ligo and Virgo makes this book an instant classic. Ben‐Gurion University, Negev, Beer‐Sheva, Israel. We consider here one of Stephen Hawking's contributions to Physics. Answer (1 of 6): Black-holes do NOT violate the second law of thermodynamics; but black-holes do introduce new aspects about how these laws work. analyze in detail how black holes can behave as information mirrors in one theorized resolution to the BHIP, as shown in [1]. Black hole entropy is a concept with geometric root but with many physical consequences. It can only increase or stay the same. This book reflects the resurgence of interest in the quantum properties of black holes, culminating most recently in controversial discussions about firewalls. The advantage of black hole thermodynamics is that provides a way to get a handle on the complex interactions black holes can have. John Dougherty & Craig Callender. The horizon area theorem [Stephen Hawking] 1970: Stephen Hawking uses the theory of general relativity to derive the so-called Horizon area theorem The total horizon area in a closed system containing black holes never decreases. However, with a negative cosmological constant, there are non-trivial black hole solutions, found by Banados, Teitelboim, and Zanelli. In these last years Black hole Physics has developed rapidly both from theoretical and observational aspects: especially as regards quantum aspects many things must be clarified as for instance the processes occuring near mini black holes with spontaneous creation of particles that eventually lead to the evaporation of black hole. Black Holes and Thermodynamics Stationary black hole ↔Body in thermal equilibrium Consider an ordinary system composed of a large number of particles, such as the gas in a box. Black Hole Information and Thermodynamics book. (19) below) must be constant over the event horizon of the black hole. Thermodynamic black holes have not just mass, charge and . It then presents black hole solutions, and discusses Penrose diagrams, black hole thermodynamics and entropy, the Unruh effect, Hawking radiation, the black hole information problem, black holes in supergravity and string theory, the black hole microstate . In order to connect with black hole thermodynamics, we realize that the photons emitted via Hawking radiation present energies of the order of the black hole's temperature E ∼ T, . Black Hole Thermodynamics. Ben‐Gurion University, Negev, Beer‐Sheva, Israel. The discovery in the early 1970s that black holes radiate as black bodies has radically affected our understanding of general relativity, and offered us some early hints about the nature of quantum gravity. John Dougherty. The Case for Black Hole Thermodynamics Part I: Phenomenological Thermodynamics. The symplectic structure of 4D . Based on Prof. L st's Masters course at the Univ. Countless lightyears far away, at the galactic core. Its first part is devoted to local strong field configurations (black holes and wormholes) in general relativity and the most . The logarithm of this number can be regarded as the entropy of the black hole and is a measure of the amount of information about the initial state which . Jacob D. Bekenstein. Hawking and G.F.R. It motivates scores of proposals in the field, from the thought that the world is a hologram to calculations in string theory. He begins with a treatment of the ordinary one-dimensional quantum harmonic oscillator, progresses through the construction of quantum field theory in flat spacetime to possible constructions of quantum field theory in curved spacetime, and, ultimately, to an . BASIC THEORY The fundamental thermodynamic relation, which contains all the information about the thermodynamic state of black hole matter, has been given by Smarr (I973) M2= 1(A/4) + (4t/A) (J2 + -Q4) + 1Q2, (2.1) where J and Q are the angular momentum and electric charge on the black hole . Thermodynamics of Spacetime: the Einstein Equation of State, T . It then presents black hole solutions, and discusses Penrose diagrams, black hole thermodynamics and entropy, the Unruh effect, Hawking radiation, the black hole information problem, black holes in supergravity and string theory, the black hole microstate . Based on Prof. Lüst's Masters course at the University of Munich, this book begins with a short introduction to general relativity. The larger the black hole . Hawking-Page phase transition:The idea is to compare the free energy, or equivalently, the actions of the Schwarzschild-AdS metric and the AdS metric. Through new analysis published in EPJ H, Carla Rodrigues . In this book, Robert Wald provides a coherent, pedagogical introduction to the formulation of quantum field . The association of the surface area of a black hole with its entropy is discussed and it is shown that with the introduction of quantum mechanics black holes cease to be black and can radiate. Quantum Field Theory in Curved Spacetime and Black Hole Thermodynamics has 1 available editions to buy at Half Price Books Marketplace The black hole is what's left. Black Holes and Thermodynamics.

- 初雪、初ボート、初エリアトラウト はコメントを受け付けていません
気温もグッと下がって寒くなって来ました。ちょうど管理釣り場のトラウトには適水温になっているであろう、この季節。
行って来ました。京都府南部にある、ボートでトラウトが釣れる管理釣り場『通天湖』へ。
この時期、いつも大放流をされるのでホームページをチェックしてみると金曜日が放流、で自分の休みが土曜日!
これは行きたい!しかし、土曜日は子供に左右されるのが常々。とりあえず、お姉チャンに予定を聞いてみた。
「釣り行きたい。」
なんと、親父の思いを知ってか知らずか最高の返答が!ありがとう、ありがとう、どうぶつの森。
ということで向かった通天湖。道中は前日に降った雪で積雪もあり、釣り場も雪景色。
昼前からスタート。とりあえずキャストを教えるところから始まり、重めのスプーンで広く探りますがマスさんは口を使ってくれません。
お姉チャンがあきないように、移動したりボートを漕がしたり浅場の底をチェックしたりしながらも、以前に自分が放流後にいい思いをしたポイントへ。
これが大正解。1投目からフェザージグにレインボーが、2投目クランクにも。
さらに1.6gスプーンにも釣れてきて、どうも中層で浮いている感じ。
お姉チャンもテンション上がって投げるも、木に引っかかったりで、なかなか掛からず。
しかし、ホスト役に徹してコチラが巻いて止めてを教えると早々にヒット!
その後も掛かる→ばらすを何回か繰り返し、充分楽しんで時間となりました。
結果、お姉チャンも釣れて自分も満足した釣果に良い釣りができました。
「良かったなぁ釣れて。また付いて行ってあげるわ」
と帰りの車で、お褒めの言葉を頂きました。
