Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

Sometimes you just need to get an ace to put your rotation over the top. The Mets sure could have used one over the weekend in Miami. They could have used someone who brings energy on the mound and ...

Abstract: Staircase approximation in the simulation of the arbitrarily irregular surface will cause artificial interference of wavefield. The body-fit coordinate transformation can accurately simulate ...

Abstract: This study introduces a methodology for vibration damping based on hybrid control of velocity (or angular velocity) and force (or torque). The hybrid velocity/force integral-proportional ...

A brain teaser is a short, playful puzzle designed to challenge your mind and elicit a smile. It could be a riddle, a tricky question, a visual illusion, or a logic twist that nudges you to think ...
