These are the things which don't seem to fit in anywhere in particular:

- Useful (Approximate) Data for Physical Calculations. (Some fundamental constants, material data, mnemonics, units & miscellaneous other bits for quick order-of-magnitude calculations.)
- Why a "minus one" in sometimes used in the calculation of standard deviations. (Some maths explained qualitatively rather than hidden under opaque algebra.)
- How to Stop Ant Infestations Humanely. (Stopping ants entering houses by feeding rather than poisoning them.)
- How to Punt. (Some recreational/sporting instruction.)
- Silent CD. (Audio files for creating a totally silent CD.)
- Patterned Dates. (Calendar dates which have numerical patterns in them.)
