A device that qualifies colleges for free stuff: By stating that students are required to purchase the TI-89 Titanium on their syllabi, colleges are qualified for free equipment and emulator software from Texas Instruments. (from department minutes)
This device is so remarkable that some students can ace a math class with it, but without it cannot add 1/2 + 1/3.
Dean's secretary: Hey, you didn't put on your syllabus that you require the TI-89 Titanium.
(Dean walks in.)
Instructor: That's right. Doesn't it seem unethical to require students to pay $150 or more for a calculator so the college gets free stuff?
Dean: No, not at all.
