, healthier, more successful lives, she said, and the act of positive thinking can be a self-fulfilling prophecy. "If you think you're more likely to get promoted, you're more likely to put in more effort and work long hours," Sharot said.But this slightly distorted view of the world can also be a weakness a person might continue to smoke because they don't expect to get lung cancer, for example. Being more realistic is important in some cases, Sharot cautioned.Physical realityPhysicists look beyond the human mind for external reality, but even that reality isn't absolute truth. Fundamental reality as scientists understand it is based on quantum mechanics, a realm where all manner of strange things occur. An electron can behave as either a particle or a wave, depending on how one measures it. And scientists can measure either a particle's position or its momentum at any given time, but never both."Quantum mechanics is simply the best theory we've ever developed," theoretical physicist David Tong, of Cambridge University, says in the show. But so much of this reality is by definition unknowable. Another physicist featured in the show, Steven Nahn of MIT, says "I absolutely believe reality is a real thing, but that does not mean we understand it." Nahn was part of the team of scientists who found evidence in 2012 for the Higgs boson, the particle that gives other particles their mass.The universe may turn out to have more dimensions than

To focus on this one line misses the nuances of the Presidents message, which includes comments about how African Americans view the Zimmerman Case in the context of the history of racial disparity in America."For more than a year, we have been listening to the conversation about this case -- from voices on every side -- and we have become very sensitive to the racial context that surrounds this case. We acknowledge Mr. Obamas remarks regarding the frustration felt by some when viewed in context of our nations history, which includes racial insensitivities spanning generations, and existing even today, including within our criminal justice system."While we acknowledge and understand the racial context of this case, we challenge people to look closely and dispassionately at the facts. We believe those who look at the facts of the case without prejudice will see that it is a clear case of self-defense, and we are certain that those who take a closer look at the kind of person George Zimmerman is -- something we understand the Department of Justice is currently doing -- we are confident they will find a young man with with a diverse ethnic and racial background who is not a racist, a man who is, in fact, sensitive to the complex racial history of our country."It takes cour
