What does the following Mathematica code do?:
defk = {k - Sqrt[2] Sqrt[Energy]};
defa = {k - Sqrt[2] Sqrt[V 0 - Energy]};
defWell = {V 0 - 10, L - 2};

Question

What does the following Mathematica code do?: 
 defk = {k -> Sqrt[2] Sqrt[Energy]}; 
 defa = {k -> Sqrt[2] Sqrt[V 0  - Energy]}; 
 defWell = {V 0  -> 10, L -> 2};

Accepted Answer

The input cells define lists of transformation rules for k, V 0  and L.  Some lists contain only single elements.

Answer

The cells don’t do anything useful, as this is not valid Mathematica syntax.

Answer

The input cells test whether variables such as defk are equal to variables such as k, once the potential and total energies are evaluated and the square roots are calculated.
