The Hidden Magnetic "Quantum Order" In Atoms

An international team of scientists, including several at The Johns Hopkins University, has detected a hidden magnetic “quantum order” that extends over chains of nearly 100 atoms in a material that is otherwise magnetically disordered. The findings, which ...

String Theory Physicist Wins Award To Help Resolve Two Mysteries

The dream of theoretical physics is to unite behind a common theory that explains everything, but that goal has remained highly elusive. String theory emerged 40 years ago as one of the most promising candidates for such a theory, and has since slipped in ...

Newton’s “Dusty Mirror” Experiment Yields New 3-D Effect

Most people think of Sir Isaac Newton as the father of gravity but he also created one of the earliest observations of interference in his “dusty mirror” experiment. In a darkened room, he used a prism and a small hole in a screen to form a quasi-monochrom ...

Magnetic Memory Of Rocks

Most continental rocks on Earth align their magnetic moments with the current magnetic field – they are said to have ‘induced’ magnetism. “I consider induced rocks to have ‘Alzheimers’. These are the rocks that forgot where they were born and how to get ho ...
