Foghorn (a call to action)

The pending U.S. destruction of Pagan and Tinian islands.

The U.S. is turning a significant portion of Micronesia into live fire and bombing ranges to train Marines. It has plans to completely take over one island for this purpose and has control of two-thirds of another island.

If people in the U.S. mainland understood the military’s plan for Micronesia they might be alarmed. But this is really happening to U.S. citizens living in America’s territories.

Flotsam (what we’re obsessed with right now)

This is a totally ordinary, not at all alarming, call for government bidders on a contract to build “new systems that employ natural or engineered marine organisms as sensor elements to amplify signals related to the presence, movement, and classification of manned or unmanned underwater vehicles.” They even adorably call these Persistent Aquatic Living Sensors PALS. Normal!
Here’s a video of anglerfish mating, because anglerfish are beauty.

Sailing by Starlight: the lost art of celestial navigation

Science

This post is a slightly modified transcript of a talk I gave on celestial navigation. As some of you know, I like to build things, and I recently decided to build some classic navigational tools. Of course, in the process of building these instruments, I had to learn how they work. The history of celestial navigation is fascinating and deeply connected to the history of astronomy and mathematics. The original slide show can be found at the bottom of this post. Enjoy!

I’m going to begin with a seemingly simple question, then hopefully give you some basic tools to answer that question. Where are you?
