Albert Einstein was the first to discover a phenomenon dubbed “spooky action at a distance” which has been finally captured by scientists. Its name is quantum entanglement, and it takes place when particles keep their connection in a way that no matter how far they are – even if we talk about miles-, they still get affected by the other.
The idea would violate the traditional way in which the world is described, so Einstein did not enjoy it. Because he hated the idea, he decided to come up with a way in which classical physics and entanglement could exist. The entangled particles pairs would communicate with one another, and their fates would be the same.
Quantum entanglement caught on image for the first time
However, Einstein’s view could not be tested in any way, and that ended up being a problem. There was a stranger alternative that consisted of the particles communicating faster than the light travels, and until the particles are observed, they have no objective. Neither this one could be tested. The existence of these hidden variables has been later disapproved in the 1960s by the physicist Sir John Bell. In the end, the quantum world was considered sophisticated and weird.
The quantum entanglement has violated Bell’s inequalities, and a group at the University of Glasgow caught that in a picture using a sophisticated system of lasers and crystals. Miles Padgett, the senior author who is a professor of physics and astronomy at the University of Glasgow in Scotland and holds the Kelvin Chair of Natural Philosophy, said that it was the pivotal test of quantum entanglement. This is the very first time when all these so-used theories could be confirmed – quantum entanglement, quantum computing and cryptography, Bell’s inequalities – by a picture.
Karen and her husband live on a plot of land in British Columbia. They aim to grow and raise a significant part of their food by maintaining a vegetable garden, keeping a flock of backyard chickens and foraging. They are also currently planning a move to a small cabin they hand built. Karen’s academic background in nutrition made her care deeply about real food and seek ways to obtain it. Thus sprung Anna’s interest in backyard gardening, chicken and goat keeping, recycling and self-sufficiency.
