We report an experimental study of the 2D dynamics of active particles driven by quantum vortices on the free surface of superfluid helium at T = 1.45 К. The particle motion at short times (< 25 ms) ...

Physicists at the University of Bayreuth have investigated the so-called Basset–Boussinesq history force acting on particles in fluids. Due to the difficulty of calculating it, this force is often ...

Keywords Learn how to solve particle motion problems. Particle motion problems are usually modeled using functions. Now, when ...

To reveal the dynamic characteristics and distribution patterns of sand particles in multiphase pumps used in closed oilfield gathering and transportation systems, this study focuses on a ...

Sitting in a restaurant, you reach for the ketchup bottle, eyeing the basket of fries in front of you. You give the bottle a ...

Researchers Mitsuyoshi Kamba, Naoki Hara, and Kiyotaka Aikawa of the University of Tokyo have successfully demonstrated quantum squeezing of the motion of a nanoscale particle, a motion whose ...

Gravity is a bully it pushes particles around so much on Earth that we rarely see their true nature. This is a feeling now ...
