In fact, a fair reading of history suggests that quantum theory is the most dramatic shift in scienceвЂ™s conception of reality since the ancient Greeks deposed mythological explanations of natural phenomena in favor of logic and reason. But everybody does agree that quantum physics has drastically remodeled humankindвЂ™s understanding of nature.

Belief that the вЂњspatial arenaвЂќ is fundamental вЂњis more a matter of convenience and convention than one of principle,вЂќ he says.Д¬arrollвЂ™s perspective is not the only way of viewing the meaning of quantum math, he acknowledges, and it is not fully shared by most physicists. вЂњEmergentвЂќ events in ordinary space are real in their own way, just not fundamental, Carroll allows. If so, all the physical phenomena we perceive are just a вЂњhigher-level emergent descriptionвЂќ of whatвЂ™s really going on. ItвЂ™s plausible, Carroll argues, that this quantum realm of mathematical possibilities represents the true, fundamental nature of reality. In a technical paper backing up his tweet, Carroll notes that quantum theory consists of equations that describe mathematical entities roaming through an abstract realm of possible natural events. вЂњWe shouldnвЂ™t fool ourselves into mistaking the world as we experience it for the world as it really is.вЂќ вЂњThe fundamental nature of reality could be radically different from our familiar world of objects moving around in space and interacting with each other,вЂќ physicist Sean Carroll suggested in a recent tweet. It taught that reality isnвЂ™t what it seems.

From cell phones to supercomputers, DVDs to pdfs, quantum physics fueled the present-day electronics-based economy, transforming commerce, communication and entertainment.Д«ut quantum theory taught scientists much more than how to make computer chips. And itвЂ™s at the heart of everything that made the century just past so dramatically unlike the century preceding it. ItвЂ™s the theory for describing the physics of the microworld, where atoms and molecules interact to generate the world of human experience.

At its roots, reality is described by the mysterious set of mathematical rules known as quantum mechanics.Д¬onceived at the turn of the 20th century and then emerging in its full form in the mid-1920s, quantum mechanics is the math that explains matter. And in the century just past, scientists have dug deep enough to discover that realityвЂ™s foundations do not mirror the world of everyday appearances. Scientists are like prospectors, excavating the natural world seeking gems of knowledge about physical reality.
