At the frontiers of theoretical physics, many of the most popular ideas have one thing in common: they begin from a mathematical framework that seeks to explain more things than our currently ...

For most people, swallowing is second nature, but how does it occur, and why do some people have difficulty with it?

A class of integro-differential equations used in the kinetic theory of gases is investigated. The existence and uniqueness of solutions to the initial value problem associated with these equations is ...

A groundbreaking mathematical equation that could transform medical procedures, natural gas extraction, and plastic packaging production in the future has been discovered. The new equation, developed ...

The mathematical model is a computer simulation that shows how muscles in the throat and esophagus move when we swallow.

This research suggests that even chaotic, unpredictable phenomena, like waves on a shore or the beating of a heart, can be ...

Most people think of history as a series of stories—tales of one army unexpectedly defeating another, or a politician making a memorable speech, or an upstart overthrowing a sitting monarch. Peter ...
