Quantum Theorists State That Wavefunctions Are Real States Not Just Statistical Tools

wavefunction-graphic

The mathematics behind the claims of a group of quantum theorists state that the wavefunction, a probability amplitude used to in quantum mechanics to describe a particle’s state, isn’t just a statistical tool but rather a real, objective state of a quantum system. The researchers published their findings in the journal Nature Physics.

Patterns of Flocks of Starlings Mathematically Behave How Magnets Would Move

starling-flock

Starlings, a small to medium-sized passerine bird in the family Sturnidae, achieve extraordinary coordination in flight and they behave mathematically as metals being magnetized. A new study published its findings in the journal Proceedings of the National Academy of Sciences.

Probabilities of Collecting All Pennies from 1959 to 1997 are Easily Feasible

lots-pennies

Many coin collectors start their numismatic collections with pennies, and trying to get pennies from every year within a given range. This process, while seemingly daunting, is straightforward and will take about 684 pennies to find all of the pennies from 1959 to 1997, since they are still in circulation.

Earth Loses 50,000 Tonnes of Mass Every Year

earth-losing-mass

According to some calculations, the Earth is losing 50,000 tonnes of mass every single year, even though an extra 40,000 tonnes of space dust converge onto the Earth’s gravity well, it’s still losing weight.

State Of The Blogosphere

Technorati publishes information about a ‘statistically significant’ study they completed. Whoever they asked what statistically significant meant didn’t give them a right answer. I don’t mean to sound overbearing, but I don’t consider a study of 1000 respondents statistically significant, that’s because I’m a math major. Definitely not enough to infer conclusions about the 1.5 million blogs that were updated this week. You need more respondents than that. Anyway, that’s just my opinion. Surveys have a way of being used anyway you what to. (via swissmiss)
