(Phys.org) -- At the heart of quantum mechanics lies the wave function, a probability function used by physicists to understand the nanoscale world. Using the wave function, physicists can calculate a system's future behavior, but only with a certain probability. This inherently probabilistic nature of quantum theory differs from the certainty with which scientists can describe the classical world, leading to a nearly century-long debate on how to interpret the wave function: does it representative objective reality or merely the subjective knowledge of an observer?

Change is never easy, but it's often essential.

Whether youre launching a start-up or looking to grow a mature business, you wont get very far unless you stick to these basics. Being around other entrepreneurial CEOs is invigorating and a great way to step back and think about the basics of your business

Streaming the Super Bowl was smart.

As part of Facebook's IPO filing, founder Mark Zuckerberg praised the concept of the "hackathon." Could something similar benefit your company, even if you're not in tech? Welcome to 2012 , a time in which hacking is praised in S-1 filings .

Researchers in the Computational Materials Group at the University of California, Santa Barbara (UCSB) have uncovered the fundamental limits on optical transparency in the class of materials known as transparent conducting oxides. Their discovery will support development of energy efficiency improvements for devices that depend on optoelectronic technology, such as light- emitting diodes and solar cells.

It's time to stop selling what you do, or make. Instead, start selling why you do it.

When things get really crazy at a start-up, an entrepreneur needs one person by their side.

Commentators are claiming that Gen Y-ers and Millennials are start-up naturals, and great salespeople.

Starting from the behavior of small flames in the laboratory, a team of researchers has gained new insights into the titanic forces that drive Type Ia supernova explosions. These stellar explosions are important tools for studying the evolution of the universe, so a better understanding of how they behave would help answer some of the fundamental questions in astronomy.

It can take years for a new engineering feat to go from concept to commercialization. The rechargeable batteries in your phone took 20 years to develop. So the federal government is launching a project to speed up invention and hopefully save U.S

The electromagnetic force has gotten a little stronger, gravity a little weaker, and the size of the smallest "quantum" of energy is now known a little better. The National Institute of Standards and Technology (NIST) has posted the latest internationally recommended values of the fundamental constants of nature.

What is the hottest problem in fundamental physics today? Physics aficionados most probably would answer: quantum gravity
