  • It’s also possible to just write a bad question/exam and recognize you need to do better as a professor.

    I had a physics professor who graded himself on whether or not he wrote/taught well by the grade distribution. He was always transparent about it and had benchmarks of how it went previous years. He was also one of the most sought after professors.

    I also had s philosophy class where the best grade over the entire semester was a 30 and the professor was like yeah this is just expected. You get an A. This guy obviously derived enjoyment from not being a good teacher and for humiliating his students that they really knew nothing about philosophy. That guy sucked.

















  • Section 4.2.3.3 of NFPA 704 guides how to handle multiple chemicals.

    You can combine the worst of each category into a composite, list each individually, or do a hybrid option.

    The posts saying there are two chemicals are true but likely incomplete… There are probably several different chemicals and they decided to go with the hybrid method.

    My guess is that they combined the worst rating of everything that doesn’t need special handling, and have a stand alone for the chemical that is incompatible with water (or even combined for several chemicals that are incompatible with water).
