>I learned something I didn't know driving Emily to school a few minutes ago. She said what is the highest earthquake magnitude? I told her to look up Richter scale on her iPhone. She said the site she looked at says there is no upper end. What kind of scale is that?

A lot of scales don't have an upper limit. For instance, there is no maximum temperature, only a minimum. The same goes for stupidity, clearly! :-)

NB! I don't mean you.... In fact, I don't have anyone particular in mind.
