Physicists Explain Sudden Stop in Sand Hourglass Flow

Credit: PixabayOlder mathematical theories may finally clarify the behavior of granular materials, which can act as solids or flow like liquids unpredictably.Consider the sand in an hourglass versus the sand on a beach. When poured slowly through a narrow opening, materials like sand, rice, or coffee flow easily. However, pouring or compressing these materials...

A More Precise Measurement of Electron Magnetic Moment was Achieved

Measurement of magnetic Moment of the electron: (a) Cryogenic system supports a 50 mK electron trap upon a 4.2 K solenoid to provide a very stable B. (b) Silver electrodes of a cylindrical Penning trap. (c) Quantum spin and cyclotron energy levels were used for measurement. Credit: Physical Review Letters (2023). DOI: 10.1103/PhysRevLett.130.071801Physicists from Havard University and Northwestern college have worked out...
