Macroscopic Coherence Explained

Coherence is a general property of a system whereby the components of that system all act in a similar manner. Coherent light is what makes lasers what they are – an alignment of photons, or waveform phases (why cats chase them is a little harder to explain). Superconductivity, a property of zero resistance to electrical flow that was formerly only observed at temperatures near absolute zero, is closely related in that the atoms of the superconducting material are aligned coherently. Quantum entanglement is an example of perfect coherence between two or more particles, in that they act as a single particle no matter how far away from each other you take them. Einstein famously referred to this property as “spooky action at a distance.” The Bose-Einstein condensate is another state of matter that exists at extremely low temperatures and involves a system of particles that have all achieved the […] Read More

When science deals with Déjà Vu

Science doesn’t believe in astral travel, and tries to give an empirical explanation for Déjà Vu. For example, we have the Dual Processing Theory, which says our memory uses two systems: one that retrieves the information and another one of familiarity (it indicates whether we have seen, heard, smelled, etc., something), so the déjà vu would happen when the second is active, but not the first. However, recent studies achieved to recreate it in a lab and they found out where it starts. So far, the unpredictable and fleeting nature of this phenomenon had made it impossible to be studied in a laboratory. Dr. Chris Moulin and the University of Leeds (UK) have succeeded provoking through hypnosis, so they can study its relation with the process of memory and human consciousness. In addition, the Moulin team has discovered there are people who have the constant feeling that the new experiences they live everyday are “familiar“. […] Read More
