Challenging the conventional wisdom on calculus

Contrary to widely-held opinion, taking high school calculus isn't necessary for success later in college calculus -- what's more important is mastering the prerequisites, algebra, geometry, and trigonometry -- that lead to calculus. That's according to a study of more than 6,000 college freshmen at 133 colleges. more...

Rough terrain? No problem for beaver-inspired autonomous robot

Researchers are using stigmergy, a biological phenomenon that has been used to explain everything from the behavior of termites and beavers to the popularity of Wikipedia, to build new problem-solving autonomous robots. more...

Engineering bacteria to exhibit stochastic Turing patterns

A new study has brought science one step closer to a molecular-level understanding of how patterns form in living tissue. The researchers engineered bacteria that, when incubated and grown, exhibited stochastic Turing patterns: a 'lawn' of synthesized bacteria in a petri dish fluoresced an irregular pattern of red polka dots on a field of green. more...

Evaluation method for the impact of wind power fluctuation on power system quality

Abrupt changes of wind power generation output are a source of severe damage to power systems. Researchers have developed a stochastic modeling method that enables to evaluate the impact of such phenomena. more...

When photons spice up the energy levels of quantum particles

For the first time, a team of mathematical physicists, call upon supersymmetry to explain the behavior of particles that have received a photon and are subjected to particular potential energies known as shape-invariant potentials. more...

Approach can help English learners improve at math word problems

Education professors have shown that a comprehension-based strategy can help English learners improve their math word-problem solving abilities. The approach boosts reading comprehension and problem solving as well. more...

Novel method for investigating pore geometry in rocks

In a fusion of mathematics and earth science, researchers have proposed a novel method for characterizing pore geometry in rock, based on persistence diagram analysis and a newly proposed parameter, the distance parameter H. The method represents heterogeneity and differences in rock type more effectively than the conventional method based on velocity distribution, without requiring costly numerical flow simulations, and the results are relatively stable with small changes in pore space. more...
