  This is the draft/updated version of a textbook on "real-world" applications
of the AdS/CFT duality for beginning graduate students in particle physics and
for researchers in the other fields. The aim of this book is to provide
background materials such as string theory, general relativity, nuclear
physics, nonequilibrium physics, and condensed-matter physics as well as some
key applications of the AdS/CFT duality in a single textbook. Contents: (1)
Introduction, (2) General relativity and black holes, (3) Black holes and
thermodynamics, (4) Strong interaction and gauge theories, (5) The road to
AdS/CFT, (6) The AdS spacetime, (7) AdS/CFT - equilibrium, (8) AdS/CFT - adding
probes, (9) Basics of nonequilibrium physics, (10) AdS/CFT - nonequilibrium,
(11) Other AdS spacetimes, (12) Applications to quark-gluon plasma, (13) Basics
of phase transition, (14) AdS/CFT - phase transition, (15) Exercises.
