But how do these abilities work? What's going on inside individual animals and the group as a whole as they protect themselves with coordinated movements?

Voters and math decideMathematical ideas and tools are often used to describe aspects of large macroscopic systems. Examples abound in areas as varied as finance to psychology. In a paper published last month in the SIAM Journal on Applied Mathematics, author Fabio Bagarello proposes mathematical models to analyze political decision-making. Using a dynamical approach which accounts for interactions between political parties and their constituents, the model tries to deduce whether parties should form coalitions under various circumstances.

Most often, those we engage with on the popular social media site are like-minded, and the ensuing electronic maelstrom of 140-character missives most often serves to reinforce, pulling us and them further along in the direction we were already trending toward—so that at the end of the day, we all tweet to the converted.

In their paper published in Proceedings of the National Academy of Sciences, the team describes how they employed mathematical models that allow for adding in randomness to catastrophe prediction models and what they found by doing so.

If four or more grains occupy a single square, that square topples by sending one grain to each of its four neighboring squares.

Similar patterns can be found on the surfaces of other dried materials, as well as in human fingerprints. While these patterns have long been observed in nature, and more recently in experiments, scientists have not been able to come up with a way to predict how such patterns arise in curved systems, such as microlenses.

In a new paper, scientists have proposed a new measure of assessment that is based on the "citation wake" of a paper, which encompasses the direct citations and weighted indirect citations received by the paper. The new method attempts to focus on the propagation of ideas rather than credit distribution, and succeeds by at least one significant measure: a large fraction (72%) of its top-ranked papers are coauthored by Nobel Prize laureates.

Two groups of researchers (Rittby, et al., and Korsch, et al.), each using a different method, came up with different locations for these resonances. Settling the dispute proved to be extremely difficult due to the fact that neither method could predict the actual resonances, but instead simply gave approximations. In fact, at the time there was no way to locate resonances with absolute certainty.

Why not apply the formula to novels? Can contents in future books be predicted based only on data from existing ones? Richard Vale at the University of Canterbury in New Zealand, said The Physics arXiv Blog, has taken on the challenge in predicting content of as yet unpublished novels in the "A Song of Ice and Fire" series by George R R Martin. The novels are the basis of the television series, "Game of Thrones." The series has five books and two more are awaited. Before proceeding, it should be emphasized that the paper comes with a spoiler alert, so avoid linking to Vale's study if you have not read the first five books.
