Spectroscopy Lab

Approaching the summer solstice, the start of fall-semester classes and their attendant labs seems far away, but a new class of St. Lawrence first-year students will be here before I know it.

Spectroscopy Lab I

This was one of the light sources students were interrogating: a sodium lamp, like the ones used in street lights (at least in the twentieth century—LED street lamps are becoming increasingly dominant now.)

Spectroscopy Lab II


Under the Learned Arches

The University of Pittsburgh’s Cathedral of Learning is overwhelming. Huge, Neo-Gothic ceilings, intricate lights, and arrays of tables decorated with busy students. I’m so amazed by this building because it’s not a library; in essence, it’s just an amazing general-use and administration building. Among these hallways are rooms decorated in the historical styles of dozens of world nations. In essence, picking a random room only contributes to the Hogwarts feeling.
