How many times have you said, “I wish the days were longer”? Well, NASA scientists say the construction of China’s Three ...

Astronomers directly imaged a faint companion star orbiting Betelgeuse, solving a decades-old mystery about its strange ...

This paper describes the eccentricity, amplitude, phase shift, angular momentum, polarization, radial path, and orbital ...

We measure the “warmness” of the dark matter, i.e. the comoving root-mean-square thermal velocity v hrms (1) , with nearly 3000 spiral galaxy rotation curves in the ...

Abstract: In this brief, a global finite-time attitude control algorithm is proposed for flexible spacecraft without angular velocity measurement. First, a global finite-time observer is designed to ...

Velocity of money measures economic health by tracking how often money changes hands. Factors like consumer savings behavior and technological advances affect money's velocity. For investors, ...

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 ...

Take away his first start of the season, one during which Bailey Ober was pitching through an illness, and by and large, the starter has been decent this season. He has a 2.85 earned-run average since ...

Abstract: We propose and experimentally demonstrate a new polarization-reciprocal angular velocity measurement scheme based on an optoelectronic oscillator (OEO) with a Sagnac loop. The scheme employs ...
