Echoes, sounds that are repeated or reverberate as a result of waves reflected back to the listener, occur in several physical systems. In physics research, echoes are typically used to eliminate the effects of dephasing ...
(PhysOrg.com) -- Since the early days of quantum mechanics, scientists have been trying to understand the many strange implications of the theory: superpositions, wave-particle duality, and the observer’s role in measurements, ...
Prof. Ehud Pines is an iconoclast. What else can you call a scientist who spent 17 years doggedly pursuing the solution to an over 200-year-old chemistry problem which he felt never received a satisfying answer using methods ...
