U-Haul Dragonfly

I've seen lots of U-Haul trucks with interesting graphics on their sides highlighting animals, events, landmarks, etc., from different states and Canadian provinces.  They call it their SuperGraphics program, and I think it's a great idea.

Here's a SuperGraphics I'm suggesting for the state of Washington, which highlights animals seen on Fidalgo Island in Puget Sound.  After all, the Happy-face Dragonfly was discovered right here on Fidalgo Island, at Cranberry Lake.


I think this would make for a great U-Haul SuperGraphics.

Dragonfly Art

The beauty of dragonflies has inspired me to try some dragonfly drawings based on my photos.  Here's one based on a photo of a Blue Dasher:


This male Blue Dasher is perched on a stem above the ground, which is typical of this species.  In fact, out of all the hundreds and hundreds of Blue Dashers I've seen over the years, I have yet to see even one perched on the ground.  They just don't like to perch there.  

On the other hand, our other blue dragonfly, the Western Pondhawk, wants to land on the ground.  It will be found on the ground unless bare ground is not available in the habitat.  Thus, a very good rule of thumb for our area is the following: Blue dragonfly on the ground = Western Pondhawk.

Merry Christmas, 2014

Season's Greetings and Happy Holidays!


Special greetings from the Happy-face Dragonfly:


To help us all get in the Christmas spirit, here's a physics problem from Walker Physics involving Santa:


The situation can be visualized as follows:


And now for the calculation:


Here's a bit of insight into the results:


Ah, nothing like a physics calculation to add to the enjoyment of a day.

Merry Christmas!
