Most will be Schrödinger's Cat which we place a living cat into a steel chamber, along with a device containing a vial of hydrocyanic acid. There is, in the chamber, a very small amount of hydrocyanic acid, a radioactive substance. If even a single atom of the substance decays during the test period, a relay mechanism will trip a hammer, which will, in turn, break the vial and kill the cat.
The observer cannot know whether or not an atom of the substance has decayed, and consequently, cannot know whether the vial has been broken, the hydrocyanic acid released, and the cat killed. Since we cannot know, according to quantum law, the cat is both dead and alive, in what is called a superposition of states. It is only when we break open the box and learn the condition of the cat that the superposition is lost, and the cat becomes one or the other (dead or alive).
There seems to be something of this within the Welsh Conservative group in the Welsh Assembly.
"It has raised as many questions as it has answered and from my point of view, I think we need clarification on this because I think confusion will otherwise arise.Contradicting what his party leader earlier insisted, Mr Ramsay said the party's constitution
"We now have a member in the Conservative group who is not a member of the party - now that is a strange situation."
"had to have been suspended in some shape or manner".
