Warp drive. Teleportation. Wormholes. A unifying "theory of everything"--maybe. In recent years scientists have been pushing the boundaries of physics, with fascinating results. Now in this special collector's edition, SCIENTIFIC AMERICAN provides a must-have compilation of updated feature articles that explore the current edge of physics.
The SCIENTIFIC AMERICAN brand has always been synonymous with authoritative, reliable information presented elegantly by the leading experts in science and technology, and this is an issue that no one with a curious mind will want to miss. - The Editors
UBERTHEORY
A Unified Physics by 2050? by Steven Weinberg
Experiments at CERN and elsewhere should let us complete the Standard Model of particle physics, but a unified theory of all forces will probably require radically new ideas.
The Theory Formerly Known as Strings by Michael J. Duff
The Theory of Everything is emerging as one in which not only strings but also membranes and black holes play a role.
Black Holes and the Information Paradox by Leonard Susskind
What happens to the information in matter destroyed by a black hole? Searching for that answer, physicists are groping toward a quantum theory of gravity.
HARNESSING QUANTA
Rules for a Complex Quantum World by Michael A. Nielsen
An exciting new fundamental discipline of research combines information science and quantum mechanics.
Quantum Teleportation by Anton Zeilinger
The science-fiction dream of "beaming" objects from place to place is now a reality-- at least for particles of light
Frozen Light by Lene Vestergaard Hau
Slowing a beam of light to a halt may pave the way for new optical communications technology, tabletop black holes and quantum computers
EXTREME EXPERIMENTS
The Large Hadron Collider by Chris Llewellyn Smith
The Large Hadron Collider will be a particle accelerator of unprecedented energy and complexity, a global collaboration to uncover an exotic new layer of reality
Cosmological Antigravity by Lawrence M. Krauss
The long-derided cosmological constant--a contrivance of Albert Einstein's--may explain changes in the expansion rate of the universe.
The Asymmetry between Matter and Antimatter by Helen R. Quinn and Michael S. Witherell
New accelerators will search for violations in a fundamental symmetry of nature, throwing open a window to physics beyond the known.
Detecting Massive Neutrinos by Edward Kearns, Takaaki Kajita and Yoji Totsuka
A giant detector in the heart of Mount Ikenoyama in Japan has demonstrated that neutrinos metamorphose in flight, strongly suggesting that these ghostly particles have mass
Extreme Light by Gerard A. Mourou and Donald Umstadter
Focusing light with the power of 1,000 Hoover dams onto a point the size of a cell nucleus accelerates electrons to the speed of light in a femtosecond.
EXOTIC SPACES
Negative Energy, Wormholes and Warp Drive by Lawrence H. Ford and Thomas A. Roman
The construction of wormholes and warp drive would require a very unusual form of energy. But, the same laws of physics that allow this "negative energy" also appear to limit its behavior.
Nanophysics: Plenty of Room, Indeed by Michael Roukes
There is plenty of room for practical innovation at the nanoscale. But first, scientists have to understand the unique physics that governs matter there.
