The Big Bang, the birth of the universe, was a singular event. All
of the matter of the universe was concentrated at a single point,
with temperatures so high that even the familiar protons and
neutrons of atoms did not yet exist, but rather were replaced by a
swirling maelstrom of energy, matter and antimatter. Exotic quarks
and leptons flickered briefly into existence, before merging back
into the energy sea.This book explains the fascinating world of
quarks and leptons and the forces that govern their behavior. Told
from an experimental physicist's perspective, it forgoes
mathematical complexity, using instead particularly accessible
figures and apt analogies. In addition to the story of quarks and
leptons, which are regarded as well-accepted fact, the author (who
is a leading researcher at one of the world's highest energy
particle physics laboratories) also discusses mysteries at both the
experimental and theoretical frontiers, before tying it all
together with the exciting field of cosmology and indeed the birth
of the universe itself.The text spans the tiny world of the quark
to the depths of the universe with breathtaking clarity. The casual
student of science will appreciate the careful distinction between
what is known (quarks, leptons and antimatter), what is suspected
(Higgs bosons, neutrino oscillations and the reason why the
universe has so little antimatter) and what is merely dreamed
(supersymmetry, superstrings and extra dimensions). Included is an
unprecedented chapter explaining the accelerators and detectors of
modern particle physics experiments. The chapter discussing the
hunt for the Higgs boson - currently consuming the efforts of
nearly 6000 physicists - reveals drama that only big-stakes science
can give. Understanding the Universe leaves the reader with a deep
appreciation of the fascinating particle realm and reverence for
just how much it determines the rich beauty of our universe.Since
the release of the first edition, the landscape has changed. The
venerable Fermilab Tevatron has ceased operations after a quarter
century of extraordinary performance, to be replaced by the CERN
Large Hadron Collider, an accelerator with a design energy of seven
times greater than the Tevatron and a collision rate of nearly a
billion collisions per second. The next few years promise to be
very exciting as scientists explore this new realm. This revised
edition of Understanding the Universe will leave the reader with a
deep appreciation of just why physicists are so excited.
