Phys.org / Quantum objects' dual nature mapped with new formula for 'wave-ness' and 'particle-ness'

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave differently depending on ...

Phys.org / The KATRIN experiment sets new constraints on general neutrino interactions

Neutrinos are elementary particles that are predicted to be massless by the standard model of particle physics, yet their observed oscillations suggest that they do in fact have a mass, which is very low. A further characteristic ...
