First mathematical analysis of gun policy tradeoff emphasizes need for more data
Is mathematics an effective way to describe the world?
Encryption is less secure than we thought
Information theory—the discipline that gave us digital communication and data compression—also put cryptography on a secure mathematical foundation. Since 1948, when the paper that created information theory first appear ...
Mathematicians calculate that there are 177,147 ways to knot a tie
Analysis of 89 models of metabolic processes finds flaws in 44 of them—but suggests corrections
Metabolic networks are mathematical models of every possible sequence of chemical reactions available to an organ or organism, and they're used to design microbes for manufacturing processes or to study disease. ...
New theorem determines the age distribution of populations from fruit flies to humans
The initial motivation was to estimate the age structure of a fruit fly population, the result a fundamental theorem that can help determine the age distribution of essentially any group.
Fluid mechanics suggests alternative to quantum orthodoxy
The central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum ...
Proving uncertainty: First rigorous formulation supporting Heisenberg's famous 1927 principle
Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle, a group of researchers from three countries has provided substantial new insight into this fundamental tenet of quantum physics ...
Computer generated math proof is too large for humans to check
Researchers use math and observation to show neural networks in crustaceans have evolved to offer optimized swimming
Math explains history: Simulation accurately captures the evolution of ancient complex societies
The question of how human societies evolve from small groups to the huge, anonymous and complex societies of today has been answered mathematically, accurately matching the historical record on the emergence ...
Soap films with complex shapes shed light on the formation of mathematical singularities (w/ Video)
(Phys.org) —Soap films with complex shapes shed light on the formation of mathematical singularities, which occur in a broad range of fields.
Hunt for an 'unidentified electron object'
New research sheds light on the nature of 'unidentified electron objects'—a mysterious class of objects that exists in superfluid helium at low temperature.
