How can a horde of active robots be automatically brought to a standstill? By arresting their dynamics in a self-sustained way. This phenomenon was discovered by physicists at Heinrich Heine ...

Robots acting as macroscale analogs of active nanoparticles stop moving through friction alone, revealing a self-sustained cooling effect without external input. (Nanowerk News) How can a horde of ...

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 ...

Fractional excitons: When quasiparticles that carry fractional charges pair up, new quantum particles are formed. (Courtesy: Demin Liu) A newly-discovered class of quasiparticles known as fractional ...

An audiogram can diagnose your hearing loss and indicate what type of hearing loss you have. It can distinguish your hearing in each ear and whether you have hearing loss on one or both sides. You can ...

While retrieval-augmented generation is effective for simpler queries, advanced reasoning questions require deeper connections between information that exist across documents. They require a knowledge ...
