In an inertial frame of reference, a body with zero net force acting on it does not accelerate. When scientists speak of inertial frames of reference, they're invoking a coordinate system with no ...

Special relativity, even though it's over 100 years old, is still one of the most puzzling and perplexing discoveries about the nature of the Universe itself. The (Newtonian) laws of physics that ...

Validity conditions for the adiabatic approximation are useful tools to understand and predict the quantum dynamics. Remarkably, the resonance phenomenon in oscillating quantum systems has challenged ...

Integrating the advantages of INS (inertial navigation system) and the star sensor, the stellar-inertial navigation system has been used for a wide variety of applications. The star sensor is a ...
