Commutation

I think this is a better choice for Word of the Day:

commutation |ˌkämyəˈtā sh ən|
noun
1 action or the process of commuting a judicial sentence. • the conversion of a legal obligation or entitlement into another form, e.g., the replacement of an annuity or series of payments by a single payment.
2 the process of commutating an electric current.
3 Mathematics the property of having a commutative relation.
ORIGIN late Middle English (in the sense [exchange, barter,] later [alteration] ): from Latin commutatio(n-), from commutare ‘exchange, interchange’ (see commute ). Sense 1 dates from the late 16th cent.


Suddenly P. Hilton seems to be a better person. She actually DID and finished her prison time.

Food Thief in Koch Building

Dear Koch Building Faculty, Researchers, Staff & Students,

For the past week, we have had a food thief eating his way through
the refrigerators in the Building 68 Tea rooms and leaving a major
mess behind him. Campus Police has stepped up their patrols of the
building. In the meantime, we do have a description of the thief:

Male, Caucasian, 5'10", short light brown hair, late 30's

There is no pattern to the time of day that he raids the fridges. If
you see him, please call Campus Police. Thanks.

Sincerely,

Mary
