Using a barometer to measure height

Normal Physics exam questions involve measuring the pressure at the two heights to work out how tall a building is.

Alternatively if you want to compare heights of two children you can place a barometer on their heads thus:

This answers the question as to whether my 12 year old son is now taller than my 15 year old daughter (who is 5'10").

Been fighting the cat for custody of the drinks cabinet again, John?

Most of us cope quite well with the marks on a doorframe method.

Happy Christmas, anyway and may 2006 bring Labour back to power in Birmingham. Lord knows, the place needs us back.

Six months for recording a court hearing - Norman Scarth

The link is in Russian about the imprisonment of Norman Scarth who is actually 85. He has a complex history including a court hearing which found that he used a chainsaw to fight off bailiffs when he was 75. [a court judgment which is disputed see comments] However, that does not justify imprisoning him for 6 months for recording a court hearing (see the link and ask google to translate it if your Russian is not up to it). It has got into the Argyll News Because he has been held such that people cannot get to him to sign paperwork an application for a writ of Habeas Corpus was made today. This has been adjourned until next week. The English judicial system is really not good at responding to major abuses of human rights by the judicial system.
