A fact from Foster's reactance theorem appeared on Wikipedia's Main Page in the Did you know column on 10 June 2010 (check views). The text of the entry was as follows:

Did you know... that Foster's reactance theorem ensures that plots on a Smith chart of an electrical network impedance function always travel around the chart in a clockwise direction with increasing frequency?

A record of the entry may be seen at Wikipedia:Recent additions/2010/June.
