Yesterday I confirmed the death of a friend. Some days ago, after a lull in correspondence, I received a very short message if his having been in the hospital thrice in 8 days; the worst was over. Then nothing for a long time.
Term having begun, which included being hired last-minute to teach a math course, I had little time to follow up. I shot the occasional email, but I knew he was down, perhaps too enervated to respond. Then it became too long. I called his company on a weekend but the answering machine was full. Yesterday I again called his company to find he had died on the 15th, just hours after his email assuring recovery.
Though never having had the good fortune to meet him in person, I came to know David extremely well, as he did me. A lover of classical music, wielder of an Olympian vocabulary, past mathematics major, computer programmer, notable businessman, and much more, he was a unique man who touched me deeply. I am a better person for having known David.
It is painful to note his passing; it still seems unreal that I will never hear from him again.
You are sorely missed, David.
Yesterday in my chemistry course's work group, there was a young woman who works in one of IUPUI's testing centers. For CHEM 105, we will take 4 computer tests outside class times at the centers; only the final is given in class. She said that from this term, only the TI-30Xa calculator will be allowed. After class I stopped at a testing center to confirm this is indeed so.
Last week I bought a $20 TI-30 XS II or something that is required for students for the math course I will teach.
For earlier math courses at Ivy Tech, I had to buy a Casio scientific calculator.
I have a little credit-card-sized basic function calculator that I got years ago for opening an account with a now-defunct Japanese bank, 北海道拓銀.
On my iPod I have two calculator programs, Scientific Graphing Calculator and i41CX+, in addition to two dedicated math programs, MathStudio (I use it often) and PocketCAS Pro.
I am heartily sick of buying new calculators, especially just to take 4 tests.
For the coming fall, I will teach a section of MATH 023, "Essentials of Algebra I," at the Lawrence campus of Ivy Tech Community College. Certainly I am looking forward to it!
Yesterday I completed the final exam for my ordinary differential equations course. The exam was comprehensive and required considering a few problems in slightly unusual ways. Grades should be posted tomorrow, and I feel I will have done rather well. Certainly I hope so!
Scored an A+!
Today is the last day of Ivy Tech's summer 2013 term. I took the last welding course needed to get the Structural Welding Certificate; it will likely be the last welding course I will take.
The introductory Python course, which ended with an A, was enjoyable like all programming courses. While I did almost all my Python work on my Windows partition, I also worked on it done under Mac. Some articles I encountered online suggested that Python installations can conflict with those supplied by Apple, which caused me to hold off on making Mac OS my Python home. With the brief summer's end break coming up, I might change that.
My tutoring for the summer has ended as well. I had a great student for MATH 136 (algebra) and 137 (trigonometry). Both are good classes and requirements for calculus I.
All that remains is my final for ordinary differential equations at IUPUI, a course which has moved quickly. It has been a very good course, low on theory but high on practicality and applications.
