This morning I was listening to the Joshua Tree by U2 in the car on the drive in to work and looked out at the eastern sky as the sun was starting to make it purple and orange. I could see the horizon which, as a any good former math teacher knows, is the root of the word "horizontal."
That lead me to put the word "horizon" together with U2 and think about the rumored title of their forthcoming album "No Line On the Horizon." I thought more about the relationship between the words "horizontal" and "horizon" and wondered if there was a word which relates to "vertical" the same way.
Then the U2 connection came full circle and I realized the word I was looking for was "Vertigo."
Hello, Hello, I thought - I wonder if they were thinking of Vertigo and vertical when they decided to write a song about horizontal. hmmmm.
