The internet contains a lot of information that is difficult to search for. One’s memory for how to spell a name fails with age and even if you find a piece of information that is important to you, if you don’t record it, it is possible for it to sink like one of those unverified island sightings during the age of discovery, and leave you tacking back and forth over the same waters muttering, “I know I saw that link here somewhere.”
Such was the case for me, with regard to the obituary notice of my high school calculus teacher, Juan Raigoza. Due to global pioneering’s recent whining about calculus, I have looked again, and found again, and now can write the post describing him and his class. Where was the link hiding? That I cannot answer, but the sadness I again feel at reading of his death suggests that perhaps my typing fingers held the telescope to a blind eye.
