Gavin Williamson, Secretary of State for Education, has devised an ingenious scheme to cope with the problems posed by the coronavirus debacle and a perfectly natural desire to keep schools open. His scheme is based on Schrödinger's cat. From Wikipedia -
In quantum mechanics, Schrödinger's cat is a thought experiment that illustrates an apparent paradox of quantum superposition. In the thought experiment, a hypothetical cat may be considered simultaneously both alive and dead as a result of being linked to a random subatomic event that may or may not occur.
Taking this idea just a little further, Mr Williamson’s plan is that school kids can be both present and absent from school at the same time as long as nobody triggers the present/absent superposition by actually checking.
Brilliant, so let us hear no more about Mr Williamson’s general uselessness here.
