In this video, we provide essential "math help" by explaining how to simplify complex fractions, which often involves careful "algebra" and understanding "rational functions". This "math tutorial" ...

In this video I present a set of problems to help prepare for learning about rational functions in precalculus. While rational functions is explored in Algebra 2 I decided to make it a separate unit ...

Probabilistic reasoning is central to many theories of human cognition, yet its foundations are often presented through abstract mathematical formalisms disconnected from the logic of belief and ...

Nanozyme is a type of nanostructured material with intrinsic enzyme mimicking activity, which has been increasingly studied in the biological field. Compared with natural enzymes, nanozymes have many ...

Microemulsions are thermodynamically stable, transparent, isotropic single-phase mixtures of two immiscible liquids stabilized by surfactants (and possibly other compounds). The assortment of very ...

Encoding precision in visual working memory decreases with the number of encoded items. Here, we propose a normative theory for such set size effects: the brain minimizes a weighted sum of an ...
