Antenna Matching
http://www.g3ynh.info/zdocs/z_matcing
The pages on impedance matching (Parts 1 and 2), including the analysis and operation of L, T and Pi networks, are excellent. The treatment of the subject includes a tiny bit of maths (R, G and jX), but that adds to the excitement.

In January 2012 a decision was to be made on retaining or dropping the leap second, the latter being the USA's proposal. The decision that actually came out was to postpone the decision until 2015!
A problem with retaining the leap second is that they will become problematically more frequent as the years go by. Currently one leap second is introduced every year or two. Centuries from now, the Earth's rotation will slow down to such a rate that several leap seconds a day will be necessary to keep Atomic Time in step with Solar Time. See the NPL website for further detail,
