Dark Side of the Moon

Next time there's a solar eclipse for my part of the world, I think I'll try listening to the "Wizard of Oz" soundtrack while watching it.

Went on sale 50 years ago today. I was never very good at drawing with it, but I remember clearing a big rectangle so I could see what was inside.

Adam's Bridge

View Larger Map

Also knows as Rama's Bridge or Rama Setu, consists of a series of limestone shoals running between Pamban Island, also known as Rameswaram Island, off the southeastern coast of Tamil Nadu, India, and Mannar Island, off the northwestern coast of Sri Lanka. Geological evidence indicates that this bridge is a former land connection between India and Sri Lanka.

Antipodes and the Earth Sandwich

If you want to dig a hole straight through the Earth to China, start digging in Argentina. This is one of the few places on land in which the antipode is not located on an ocean. With most of the Earth's surface covered by water and most of the land area in the Norther Hemisphere, this is not really surprising.

Ze Frank has a project to create "Earth Sandwiches", which is created when two slices of bread are simultaneously placed on opposite sides of the Earth. To assist this project, his website has a Google Maps tool that can display the antipodal spot of any place mark.

There is an area in northern Montana that is opposite from the Kerguelen Islands in the South Indian Ocean. There is also a small island, Île Amsterdam, antipodal to spot southeast of Lamar, Colorado and Île Saint-Paul, which is opposite from Firstview, Colorado. These are the only land areas antipodal to the Lower 48 United States.

Previously Newer

I can't be the only person who has trouble figuring out how the arrow of time flows through some blogging engines. I find it non-intuitive when I have to click on "Next" to see older posts and then "Previous" to see newer posts.
