Samuel Arbesman Explains The HalfLife of Facts
In Samuel Arbesman’s new book The HalfLife of Facts: Why Everything We Know Has an Expiration Date, the applied mathematician examines why in the modern world, facts change all of the time. Read more @ SciTechDaily

New Mathematical Proof of the ABC Conjecture
A new claim could imply that a proof of one of the most important conjectures in number theory has been solved, which would be an astounding achievement. Mathematician Shinichi Mochizuki of Kyoto University in Japan has released a 500page proof of the abc conjecture that proposes a relationship between whole numbers (related to the Diophantine…

CenturyOld Goldbach Weak Conjecture Closer to Being Solved
The weak Golbach conjecture states that you can break up any odd number into the sum of, at most, three prime numbers. Prime numbers cannot be evenly divided by any other number than themselves or 1. Read more @ SciTechDaily

Patterns of Flocks of Starlings Mathematically Behave How Magnets Would Move
Starlings, a small to mediumsized 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. Read more @ SciTechDaily

Probabilities of Collecting All Pennies from 1959 to 1997 are Easily Feasible
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. Read more @ SciTechDaily

Earth Loses 50,000 Tonnes of Mass Every Year
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. Read more @ SciTechDaily

Touch Pilot S01E01 (Fox)
I was initially surprised that Kiefer Sutherland was back on network television, but I have always like 24 so I was actually looking forward to the series on Fox. This series was written and created by Tim Kring, who’s known for Heroes. The series uses some of the techniques from that series, so if you’ve watched…

The Fractal Dimension of the US ZIP Code System: 1.78!
While most people think that ZIP codes were originally created randomly, there is actually an order to the US mail system. Since it turns out that it has a branching structure, it implies that it has a fractal dimension. Samuel Arbesman of Wired’s Social Dimension used the ZIPScribbles images created by Robert Kosara to calculate…

Mathematician Claims Breakthrough in the Sudoku Problem
While you might just need a pencil and your brain to fill in this week’s Sudoku puzzle, an Irish mathematician used millions of hours of supercomputing time in order to solve an important open problem in the mathematics of Sudoku; the game that was initially popularized in Japan and involves filling up a 9×9 grid…
