I just won a bet I made in 2002 with physicist Michio Kaku. I bet him $1,000 that “by 2020, no one will have won a Nobel Prize for work on superstring theory, membrane theory, or some other unified theory describing all the forces of nature.” This year’s Nobel Prize in Physics, which recognized solid work in cosmology (yay Jim Peebles!) and astronomy, was Kaku’s last chance to win before 2020. Kaku and I made the bet under the auspices of Long Bets, a “public arena for enjoyably competitive predictions, of interest to society, with philanthropic money at stake.” Long...

When he died on September 7, 2012, theoretical physicist Claud W. Lovelace left behind a house filled with parakeets. With no family or close companions, the eccentric Rutgers professor loved to be surrounded by his colorful fine-feathered friends and listen to classical music as he contemplated the nuances of unified field theory. A loner not particularly close to his colleagues, members of the Physics and Astronomy department were astounded and delighted when he willed his entire fortune of $1.5 million to it. The funds were used to help establish endowed positions in practical fields of physics, a far cry from...

Strings attached Wanted: Proof that the mother of all theories is correct. Pathik Guha reports But is that physics? That seemed to have been the caveat raised by Richard Feynman, Nobel laureate physicist, against the string theory, popularly known as the Theory of Everything. Though the experts, not particularly fond of hypes, don’t like the name that much, the string theory is one of the attempts to unify the two seemingly irreconciliable concepts — relativity and quantum mechanics — which between them explain everything from an apple’s fall to a picture’s formation on a TV screen. Albert Einstein, always...

The Growth of Inflation Twenty-five years after Alan Guth turned cosmology on its head, what's the latest story of the universe's first moments? by Davide Castelvecchi Photo: Fred Ullrich It was a true Eureka moment if there ever was one. On the night of December 6, 1979, an obscure Stanford Linear Accelerator Center postdoc was up late, sweating over an even more obscure problem about particles called magnetic monopoles. Looking at his calculations the next day, the usually low-key Alan Guth annotated the words "SPECTACULAR REALIZATION" at the top of the page. Guth had discovered cosmic inflation, an idea which...

December 7, 2004 String Theory, at 20, Explains It All (or Not) By DENNIS OVERBYE SPEN, Colo. - They all laughed 20 years ago. It was then that a physicist named John Schwarz jumped up on the stage during a cabaret at the physics center here and began babbling about having discovered a theory that could explain everything. By prearrangement men in white suits swooped in and carried away Dr. Schwarz, then a little-known researcher at the California Institute of Technology.Only a few of the laughing audience members knew that Dr. Schwarz was not entirely joking. He and his...
