Throwback Thursday – Brockport Chemistry take 2

Last week, I posted an early photo of a Chemistry lab from Brockport.  Not to be outdone, my wife Rozenn (historian of the Western Monroe Historical Society at the Morgan Manning House) found this picture in one of her books:The caption for the picture reads:

The [Brockport] Chemistry Laboratory: The 1899 yearbook describes the chemistry laboratory as “one of the best appointed in the state, having ample table room for 50 students at one time … The department has over $2,500 worth of physical apparatus, over 2,500 stereopticon slides and some 3,000 specimens.”

That $2,500 in instrumentation would be a bit over 70 thousand in today’s dollars, and I’m happy to say that our department has far more instrumentation than that.  The reference to thousands of specimens and stereopticon slides got me thinking about what was taught in Chemistry 118 years ago (hey that’s one year for every element on the periodic table).  A quick web search brought me to this article, (which is behind a paywall if you don’t have access to ACS journals) that reviews an historical Chemistry textbook from 1809.  It was written by Jane Marcet to “… provide women with a method of educating themselves in chemistry …” and uses a conversational style that is not seen in contemporary instructional materials.  This #ThrowbackThursday has me thinking about revisiting some teaching styles (to justify procrastinating on that pile of grading for one more day).

Throwback Thursday – Brockport Chemistry edition

From the Daily Eagle, courtesy of librarian Charlie Cowling, a snapshot of Chemistry instruction from the 1950s.  Apparently, Chemistry wasn’t dangerous enough to necessitate safety goggles back then, (but it was too dangerous for girls…).  How times have changed.

Back in the 1950s the College was, as its own literature stated, a “single purpose” institution, and that purpose was teacher training. Later in the mid-1960s the College would as part of its ongoing expansion become a comprehensive liberal arts college, with various majors, such as chemistry for example. But before then we still were teaching chemistry here, to aspiring science teachers, and one of the faculty was Robert Brandauer, who taught here from 1946-1970.

In a 1947 Stylus article he is described as “…the man with a million dollar smile…” He had an MS in Chemistry from Cornell (1939,) and at the time was working on his doctorate. In a curious coincidence he had previously taught at Roberts College in Istanbul, where Professor Martin Rogers had also taught. Faculty like Brandauer were in from the beginning of that incredible arc the school traveled, from a small teachers college with less than 1,000 students to a major comprehensive institution with almost 10,000 students.

It’s not purple, it’s mauve…

My wife has been tending to these orchids for a number of years.  When we were in Chicago, they looked kind of sad.  They seem to like the Brockport air (which has much less traffic pollution, so I don’t blame them).

Click on the picture to get a bigger image.  The purple orchid seems to be very pleased by finally having a non-south-facing window to sit in.  Speaking of purple, today is Henry Perkin’s 180th birthday (thank you for honoring a Chemist, Google).  Perkin is known for discovering a way to produce purple dye.  His story, which is detailed in a very readable book by Simon Garfield, is worth picking up if you have a few hours to spare.

A Maker Family

A few weeks back, my wife (Rozenn) came home with a broken cane chair, which looked something like this, and wanted to try repairing the seat. A few tours through youtube videos, a visit to Amazon and some time with my Dremmel (she’s logged more hours on that thing than I have) and she managed to replace the seat.  Even I can sit in it!

Now that it’s completed, I think we both agree that the project was very doable.  The hardest part was removing the old spline (don’t believe those Youtube videos where it comes out with one tap of a chisel).  Once the spline was removed, however, the rest of the process was a breeze.  Yard-sale season may be wrapping up, but I’m sure we’ll find a few more broken chairs at rock-bottom prices that will not only give us a fun project, but also result in a nice-looking chair in the end.

OMIS remix

Here’s the first published remix of my Open Millifluidic Inquiry System (OMIS) made by Thingiverse member Steve Gordon.  There are a couple of nice tweaks, including the use of epoxy to keep the support rods in place (a semi-permanent solution, since many epoxies can dissolve in acetone, and since PLA was used in this build, OMIS won’t be permanently damaged by an acetone treatment).  Another nice tweak is the use of automatic pipette tips instead of syringe needles to connect the syringes to the millifluidic device.  I’ve got some projects that will involve acid in one of the channels, so I need to explore this hack further.

More information about OMIS, such as the bill of materials, build guide, and some ideas on how to use it can be found on my OMIS page.
