I&#8217;m pretty sure I would do something in science, and I have an interest in evolution and paleontology.  The stumbling block to going in that direction was the squishy part of biology \u2014 when I was in school, I was pretty sure animal dissection would start by making me weak-in-the-knees, followed by me throwing up, and I had no desire to test that prediction.  Consequently, I haven&#8217;t studied a whole lot of biology, including entomology.<\/p>\n<p>But dragonflies are pretty fascinating.  They don&#8217;t fall under the &#8220;bugs to be avoided&#8221; category \u2014 not gross house-invaders, nor do they want to sting me.  I had no idea that they flap their sets of wings out of phase, though it makes sense (if it were in phase, why not just have a bigger wing?)  But I have some shots where it looks like maybe the two sets are at slight different frequencies, so the phase changes.  I also didn&#8217;t realize how much they glide when they fly.  And the flapping is low enough in frequency that it shows up well on a high-speed camera \u2014 a much lower pitch than many other insects.<\/p>\n<p><object class=\"embed\" width=\"425\" height=\"264\" type=\"application\/x-shockwave-flash\" \ndata=\"http:\/\/www.youtube.com\/v\/yI2DOF9gjkY?fs=1\"><param name=\"wmode\" value=\"transparent\" \/><param name=\"movie\" value=\"http:\/\/www.youtube.com\/v\/yI2DOF9gjkY?fs=1\" \/><em>You need to a flashplayer enabled browser to view this YouTube video<\/em><\/object><\/p>\n<p>It&#8217;s also really hard to pan a camera to follow them.
