Schrödinger's cat

Frae Wikipedia, the free beuk o knawledge
Schrödinger's cat: a cat, a flask o poison, an a radioactive soorce are placed in a sealed box. If an internal monitor detects radioactivity (i.e., a single atom decayin), the flask is shattered, releasin the poison that kills the cat. The Copenhagen interpretation o quantum mechanics implies that efter a while, the cat is simultaneously alive an dead. Yet, when ane looks in the box, ane sees the cat either alive or dead, nae baith alive an dead. This poses the quaistien o when exactly quantum superposeetion ends an reality collapses intae ane possibility or the ither.

Schrödinger's cat is a thocht experiment, whiles describit as a paradox, devised bi Austrick pheesicist Erwin Schrödinger in 1935.[1] It illustrates what he saw as the problem o the Copenhagen interpretation o quantum mechanics applee'd tae everyday objects. The scenario presents a cat that mey be simultaneously baith alive an dead,[2][3][4][5][6][7][8] a state kent as a quantum superposeetion, as a result o bein linked tae a random subatomic event that mey or mey nae occur.
