Local realism is something we live with every day, even if we don’t realize it. The principle of local realism combines two assumptions: locality and realism. Locality says that distant objects cannot directly and instantaneously influence each other (since nothing can travel faster than the speed of light). Realism says that the things we measure and sense are indeed really there apart from our measurements, and it’s not just our measurements that make them exist.

Quantum theory states that there is no local realism. In other words, an object has no pre-existing values until that object is measured. Until then, there is only probability. The theory also suggests that a single measurement may affect two remote, distinct systems described by "entangled" quantum states.
For example, the theory says that if two entangled particles (ions, protons, electrons, etc.) are sent off to remote places, a measurement taken on one particle at one point should indicate the states (position and speed, for example) of both particles, no matter the distance between the two particles.
Einstein's theory of relativity claims this would be impossible because the particles would have to communicate with one another faster than the speed of light. When considering the local realism for physics laws, the quantum theory could not be complete, Einstein reasoned.

The boson earned a nickname - the "God particle" - supposedly because of its importance to the Standard Model. But Prof Higgs stated that he disliked the term because it "might offend people who are religious".

This week, in an interview with the Spanish newspaper El Mundo, Prof Higgs criticised fellow academic - and staunch atheist - Richard Dawkins for his stance towards religious believers.

Prof Higgs said: "What Dawkins does too often is to concentrate his attack on fundamentalists. But there are many believers who are not fundamentalists. Fundamentalism is another problem. I mean, Dawkins in a way is almost a fundamentalist."

He said he was not religious, but added that "maybe that's just more a matter of my family background than that there's any fundamental difficulty about reconciling the two".

In 2011, Prof. Derman published a new book titled Models.Behaving.Badly: Why Confusing Illusion With Reality Can Lead to Disaster, on Wall Street and in Life. In that work he decries the breakdown of capitalism as a model during the bailouts characterizing the 2008 financial crisis and calls for a return to principles, to the notion that if you want to take a chance on the upside, you have also taken a chance on the downside. More generally, he analyzes three ways of understanding the behavior of the world: models, theory and intuition. Models. he argues, are merely metaphors that compare something you would like to understand with something you already do. Models provide relative knowledge. Theories, in contrast, are attempts to understand the world on absolute terms; while models stand on someone else's legs, theories, like Newton's or Maxwell's or Spinoza's, stand on their own. Intuition, the deepest kind of knowledge, comes only occasionally, after long and hard work, and is a merg
