Abstract: In this paper, a strategy to detect the rotation direction in angular displacement and velocity sensors based on rotors loaded with circular chains of split ring resonators (SRRs) is ...

Abstract: This paper addresses the problem of designing an angular velocity observer and an output feedback attitude controller with finite-time convergence and disturbances for spacecraft. First, two ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

During the cold autumnal months of 1905, German theoretical physicist Albert Einstein published a scientific paper that spoke about the properties of light and time. In the paper, he also included an ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

In the early days of Formula 1, mechanics hammered wheels on with mallets. Today, a single centrelock wheel nut is a masterpiece of design, built for speed and safety. That evolution explains why one ...

For more than a decade, Henry Chen has inspired students in his Westwood Regional High School physics classroom — now, his students are rallying to save his life. Chen, known for his after-school ...
