Add Yahoo as a preferred source to see more of our stories on Google. A new accelerating wave equation links changing light speeds to relativity, momentum conservation and the arrow of time. (CREDIT: ...

Sound, light and water waves all move through space dynamically, and their behavior can be difficult to predict in advance. Over time, mathematicians have developed equations to capture complex wave ...

Boundary control in wave equations concerns the manipulation of wave phenomena by prescribing inputs or feedback at the spatial boundaries of a domain. This approach exploits the hyperbolic nature of ...
