Decision theory in economics, psychology, philosophy, mathematics, and statistics is concerned with identifying the values, uncertainties and other issues relevant in a given decision, its rationality, and the resulting optimal decision. It is closely related to the field of game theory as to interactions of agents with at least partially conflicting interests whose decisions affect each other.
String Theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity. It is a contender for a theory of everything (TOE), a self-contained mathematical model that describes all fundamental forces and forms of matter. String theory posits that the elementary particles (i.e., electrons and quarks) within an atom are not 0-dimensional objects, but rather 1-dimensional oscillating lines ("strings").
Now, scientists have the technology to begin looking for evidence that could reveal the physics of Einstein’s general relativity. The best prospect for testing the theory is to look for ripples in space-time, known as gravitational waves, as well as the properties of gravitational waves
Prospect theory. Dan Kahneman and Amos Tversky’s behavioural economics theory modeling how we make decisions. It illustrates, among other things, some of the non-rational decisions we make as we are guided by emotion and heuristics in decisions. The...
Pandora Puts Itself on the Block, But Who Would Want to Buy It?
In theory, Apple, Google (GOOG, +0.10%), or Amazon might be interested in adding 80 million or so monthly users, on the assumption that they could convince at least some of them to upgrade to a paid account. Or they could just wait for Pandora to go under, and bank on the prospect of picking up some of its users eventually anyway, without having to pay anything at all.
In a 2011 interview with The Guardian, Hawking addressed how he feels about his own mortality. "I have lived with the prospect of an early death for the last 49 years," he said. "I'm not afraid of death, but I'm in no hurry to die. I have so much I want to do first."
