What’s the most difficult question you’ve been asked as a maintenance instructor?
Blye Widmar
"Where are the prints?!"
This was the final question in an onslaught of verbal feedback, comments, and critiques I received from my students back in 2019. I had two years of instructor experience and was teaching a class that had been meticulously rehearsed in preparation for an accreditation visit. I knew the training material well and transferred that knowledge effectively enough for all the students to pass the class. As we wrapped up, I asked the students how they felt about my first big system-level class, and they did not hold back.
“Why was the exam from memory when we don’t work from memory in the plant?” “Why didn’t we refer to the vendor documents?” “Why didn’t we practice more on the mock-up?” And so on.

The electrical resistivity of high purity liquid cesium was determined in a pressurized furnace from 600 to 3000°F (316 to 1649°C) by measurements of the electrical resistance of a Ta-10%W alloy tube, both empty and filled with cesium. The resistivity found for the lower temperatures agrees moderately well with previously published results, the discrepancy decreasing at the highest temperatures. The thermal conductivity of liquid cesium was calculated from its resistivity using a Lorenz number of 2.3 × 10−8 (V/deg K)2. By comparing the cesium data with a reduced resistivity vs reduced temperature curve for mercury, the critical temperature of cesium is found to be 3190 °F (1754 °C), with a corresponding critical pressure of 130.8 atm from an available vapor-pressure correlation.
