The second edition of the new blog carnival Math Teachers at Play was posted this morning at Let’s Play Math.
The carnival has a wide variety of mathematical posts from elementary to advanced as well as posts on math education. Interspersed between the posts are interesting quotations such as the following from Hugo Rossi.
In the fall of 1972 President Nixon announced that the rate of increase of inflation was decreasing. This was the first time a sitting president used the third derivative to advance his case for reelection.
