`dir(obj)` calls `__dir__`, and `__dir__` returns a sorted list. We can override `__dir__` to return an unsorted list. Had a play and think I've worked out how to do it....

When you've created columns for some_values and factors, you've provided a list of quantities, which pandas treats as objects - and you see this when looking at the dtypes. When...

You aren't telling pandas to store the data using a PintArray so it converts it to a ndarray of objects. You need to use the dtype argument: ``` import pint...

`df['quantity'] = df.apply(lambda x: Quantity(x['variable_value'], x['unit']), axis=1).astype("pint[Hz]") ` it does not look correct; when you can see the unit in the column you can tell it's not read it correct...
