The Pentagon’s hypersonic ambitions have become a magnet for rumor, with online sleuths convinced a secret “ghost jet” is already streaking through the upper atmosphere while official programs stumble ...

Little is known about the long-destroyed moon-forming planet, Theia. But it may have been born in the inner solar system—just like Earth—a new study suggests ...

While atmospheric turbulence is a familiar culprit of rough flights, the chaotic movement of turbulent flows remains an unsolved problem in physics. To gain insight into the system, a team of ...

Imagine standing on top of a mountain. From this vantage point, we can see picturesque valleys and majestic ridges below, and streams wind their way downhill. If a drop of rain falls somewhere on this ...

Strengthen your Physics score with these exam-level problems covering friction, circular motion, pulleys, collisions, and ...

Using Java's Swing library, this projectile physics simulator allows the user to control a small block by applying forces to it, launch projectiles from the block, and freeze and unfreeze the ...

Recent developments in trapped-ion platforms are opening towards quantum simulation of chemical dynamics. Here, the authors demonstrate independent control of spin-phonon coupling and reservoir ...

DAHLGREN, Va.  –  Naval Surface Warfare Center Dahlgren Division recently fired high-speed projectiles into timed explosions ...

Abstract: Determining an analytical solution to the inverse kinematics problem for a parallel manipulator is typically a straightforward problem. However, lower mobility parallel manipulators with 2-5 ...

Abstract: Unit commitment (UC) problems are typically formulated as mixed-integer programs (MIP) and solved by the branch-and-bound (B&B) scheme. The recent advances in graph neural networks (GNN) ...
