Physics problem: equilibrium for a leaning ladder

Solve the classic physics problem of equilibrium for a leaning ladder! This guide helps you understand how to calculate the forces acting on a ladder in equilibrium, considering friction, normal force ...
Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...
Quantum physics has a reputation for needing exotic hardware, from liquid-helium-cooled qubits to sprawling AI clusters, just ...
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) ...
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 ...
