Mindful of such pitfalls, Saif rejected his father's proposal last year to assume the country's second-highest post. "I would not accept [a position] because you need to have a constitution," Saif says. "You need transparent political rules of the game." He's also prepared to test the system. Tensions erupted into full view last December after Saif invited the Washington and Middle East directors of Human Rights Watch to launch its report on Libya's human-rights violations at a press conference in the heart of Tripoli. Few groups had ever been allowed to speak out publicly...

...works like this: Across the post-Big Bang universe, collections of Higgs bosons make up a pervasive Higgs field - which is theoretically where particles get mass. Moving particles through a Higgs field is like pulling a weightless pearl necklace through a jar of honey, except imagine that the honey is everywhere and the interaction is continuous. Some particles, such as photons, which are weightless particles of light, are able to cut through the sticky Higgs field without picking up mass. Other particles get bogged down, accumulating mass and becoming very heavy. Which is to say that even though the universe...
...find the Higgs boson is to create an environment that mimics the moment post-Big Bang. The powerful LHC runs at up to 7 trillion electron volts (TeV) and sends particles through temperatures colder than deep space at velocities approaching the speed of light. (The second most powerful particle accelerator, at Fermilab in Illinois, runs at 1 TeV.) The added juice allows scientists to get closer to the high energy that existed after the Big Bang. And high energies are needed, because the Higgs is thought to be quite heavy. (In Einstein's famous equation E=MC2, C represents...
