Interpretation of quantum mechanics
Quantum mechanics is a physical theory which is extremely perplexing and non-intuitive. The equations have been very successful in predicting experimental results, but there have been a wide range of interpretations of what those equations mean.Three of the most common interpretations are summarized here:
| Interpretation | Deterministic | One Universe |
Avoids hidden variables |
Local | Avoids collapsing wavefunctions |
Copenhagen interpretation | No | Yes | Yes | No | No |
|---|---|---|---|---|---|
| Everett many-worlds interpretation | Yes | No | Yes* | Yes | Yes |
| Bohm interpretation | Yes | Yes | No | No | Yes |
An interpretation with a Yes in every box would be the most elegant and intuitive, but Bell's inequality appears to show that this is impossible within the rules of quantum mechanics. The possibility that the rules of quantum mechanics are in error and that the actual theory of the universe is one in which all of the boxes are yes has also been explored experimentally and there have been several experiments that appear to experimentally confirm Bell's inequality and the rules of quantum mechanics.
Each of these interpretations has at least one No, but they differ in where it is. At the current time, there are no known practical experiments that can distinguish between these interpretations, although there appears to be one highly impractical one known as quantum suicide that does. Attempting to find experiments that could distinguish between the different interpretations is an area of active interest.
Dismay not (Princes) at this accident,
Care is no cure, but rather corrosiue,
Let frantike Talbot triumph for a while,
Wee'le pull his Plumes, and take away his Trayne,
And of thy Cunning had no diffidence,
And we will make thee famous through the World
Alans. Wee'le set thy Statue in some holy place,
Employ thee then, sweet Virgin, for our good
Pucell. Then thus it must be, this doth Ioane deuise:
We will entice the Duke of Burgonie
France were no place for Henryes Warriors,
But be extirped from our Prouinces
Alans. For euer should they be expuls'd from France,
To bring this matter to the wished end.
Drumme sounds a farre off.
Hearke, by the sound of Drumme you may perceiue
And all the Troupes of English after him.
French March.
Now in the Rereward comes the Duke and his:
Summon a Parley, we will talke with him.
Trumpets sound a Parley.
Charles. A Parley with the Duke of Burgonie
Burg. Who craues a Parley with the Burgonie?
hence
Charles. Speake Pucell, and enchaunt him with thy
Stay, let thy humble Hand-maid speake to thee
Burg. Speake on, but be not.
