Mathematics is the study of quantity, space, structure, and change. Mathematicians seek out patterns and formulate new conjectures. Mathematicians resolve the truth or falsity of conjectures by mathematical proofs, which are arguments sufficient to convince other mathematicians of their validity. The research required to solve mathematical problems can take years or even centuries of sustained inquiry. Since the pioneering work of Giuseppe Peano, David Hilbert, and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. When those mathematical structures are good models of real phenomena, then mathematical reasoning often provides insight or predictions. Through the use of abstraction and logical reasoning, mathematics evolved from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity for as far back as written records exist. Rigorous arguments first appeared in Greek mathematics, most notably in Euclid’s Elements. Mathematics continued to develop, for example in China in 300 BC, in India in AD 100, and in the Muslim world in AD 800, until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that continues to the present day. — Wikipedia (Math Skills)

(Cornell University) How does the Japanese tree frog figure into the latest work of noted mathematician Steven Strogatz? As it turns out, quite prominently. Cornell researchers used the curious mating ritual of male Japanese tree frogs as inspiration for their exploration of 'swarmalators'  their term for systems in which both synchronization and swarming occur together.

(PLOS) A new computational model of heart tissue allows researchers to estimate the probability of rare heartbeat irregularities that can cause sudden cardiac death. The model, developed by Mark Walker and colleagues from Johns Hopkins University, Baltimore, and IBM Research, Yorktown Heights, N.Y., is presented in PLOS Computational Biology. […]

(Lobachevsky University) Lobachevsky University (UNN) scientists, Associate Professor of the History and Theory of International Relations Department Alexander Petukhov and Head of the Department of Psychophysiology Sofya Polevaya, are studying the modeling of the cognitive dissonance phenomenon. They rely on the theory of information images and a mathematical model developed on the basis of this theory. […]
