In January I wrote a piece titled “ 5 Physics Equations Everyone Should Know .” Lots of you weighed in with your own nominations, and there were plenty of good suggestions. So I’ve decided to do a ...

When you shine a flashlight into a glass of water, the beam bends. That simple observation, familiar since ancient times, hides one of the oldest puzzles in physics: what really happens to the ...

Abstract: A cart-double pendulum (CDP) system is a nonlinear underactuated mechanical system with three degrees of freedom (DOF) and two control inputs. This brief studies two motion control problems ...

Abstract: The inverted pendulum is modeled by Associated Linear Equations in its discrete version (Non-linear with Auto-Regressive inputs NARXs). Its homogeneous and particular response is evaluated ...

The Atacama Large Millimeter/submillimeter Array (ALMA) has captured the motion of spirals of dust around a young star and shown that the winding motion of the spiral pattern is conducive to planet ...

A rack and pinion steering system consists of a pinion (a circular gear) with a rack (a linear gear). The system works by converting a revolving motion into linear motion. Most cars, small trucks, and ...

He was working as a “quant” in his first job out of college. That’s hedge-fund speak for a stock-trading analyst at a statistical-model-driven quant fund. But like many people who spend their energy ...

Patrick Mahomes will turn 30 years old next week, and he may not be quite as spry as when he first became the Chiefs starting quarterback in 2018, he still manages to amaze. In the Chiefs’ 27-21 loss ...
