Over the last week I found myself working on graphics for calculus (arc length and linearization) which required learning a bit about the spy capabilities of tikz. Spy allows you to magnify a part of your picture which is useful when you're dealing with small changes as is typical in calculus. After creating said graphics it seemed only appropriate that I create a plot template which uses spy. I've worked the capability into the previous plot template for consistent plotting graphics; you can see the output above. That's for illustrative purposes only; in my opinion there's too much happening in the picture above: so many functions, the grid and the spy area, and the vertical line. Recall that changing the "grid" option from "both" to "none" will turn off the graph paper. The new template is posted on the Handouts page, under the first template.
Here are some issues that caught my eye recently:
- A NY school district is apologizing after letting a student recite the Pledge of Allegiance in Arabic during National Foreign Language Week. Fury follows and the article mentions a tweet: "State Education Department regulations specifically say the Pledge of Allegiance should be read in English.".
- Illinois Watchdog reports "After working one day as a substitute teacher in Illinois, David Piccioli could be entitled to an annual pension of more than $30,000." This story is attracting attention and is well worth reading.
- Chessbase hosts John Stewart's piece on U.S. buying (chess playing) nerds. No offense Fabiano!
- RT reports on over 1,000 arrested in a mass cheating scandal. Watch the video of them scaling walls to position themselves by windows to help out. The article notes,"More than 1,000 people were detained, half of them were parents and teachers while the other half consisted of friends and relatives," Gupteshwar Pandey, a police official in Bihar state, told AFP on Sunday. "Fifty percent have been released but I believe that the others are still probably in jail." followed by "According to Pandey, at least two policemen were also arrested and 10 more were dismissed after being implicated in the scam." and "Numerous photos and a video presented earlier this week showed the students using smuggled crib sheets, which friends and relatives had handed to students after climbing the walls of examination centers." You have to see it to believe it.
