Volcanic Vortex Ring

Why In News:

·       Volcanic Vortex Rings (VVR) observed from the Mount Etna

Volcanic Vortex Rings:


·       Also known as – Volcanic Smoke Rings

·       Formation – Generated when gas, predominantly water vapor, is released rapidly through a vent in the volcanic crater.

·       The rings can remain in the air for up to 10 minutes, but tend to disintegrate quickly if conditions are windy and turbulent.

Mount Etna



·       It is sometimes referred to simply as Etna, is an active volcano on the east coast of Sicily, the largest island in the Mediterranean Sea.

·       Etna’s peak is the highest in Italy south of the Alps, and it is Europe’s largest and one of the most active volcanoes.

·       Etna’s summit has five craters, which are responsible for most of the volcano’s eruptions; there are also “flank” eruptions that occur out of 300-odd vents of varying sizes along the slopes of the mountain.

·       It is in almost constant activity, and has seen, since the year 1600, at least 60 flank eruptions and many more summit eruptions.

  Quantum Nonlocality: §   While classical physics assumes locality, the principle of nonlocality is a feature of many interpretations of quantum mechanics. §   Nonlocality describes the apparent ability of objects to instantaneously know about each other’s state, even when separated by large distances (potentially even billions of light years), almost as if the universe at large instantaneously arranges its particles in anticipation of future events. §   This is in direct contravention of the "principle of locality" (or what Einstein called the "principle of local action"), the idea that distant objects cannot have direct influence on one another, and that an object is directly influenced only by its immediate surroundings, an idea on which almost all of physics is predicated. §   Non locality occurs due to the phenomenon of entanglement, whereby particles that interact with each other become permanently correlated, or dependent on each other’s states a...
