Mystery of science in the sacred

In my last post I noted there are two Catholic scientists who are honored in virtually every Catholic church in the United States.  And for that matter, many other worship spaces across the world.

Who are they?  Not Galileo.  Or Luke, the physician.  You aren't likely to find them in the stained glass windows, and you might have to open a cupboard or a drawer to find them.

One French, one Italian. Both men. Working at the turn of the 18th century to the 19th.  A mathematician turned physicist and a chemist.

Ready for the answer?

Andre-Marie Ampère and Alessandro Volta.  Both have units named after them, to honor their work, the ampere (amp) and the volt respectively.  Both these memorials are in evidence on the power supply shown in the first photo, e.g. 12V, 12 volts; 2.5A, 2.5 amperes.  Photo taken in the sacristy at my parish!
