Thinking About Waves

By -
We go out to Lake Jordan some Sundays, for a kayaking adventure. This past weekend, we took a tandem out for a couple hours, myself, Susan, and Benji in his life vest (he actually has two!).

Across the channel, off to the west, around the big bend of the shore. We pulled into a little beach and we all jumped out of the kayak for a swim in the very warm water. The lake bottom, all clay and silt, was squishy with dead sticks popping out. In the middle of the lake, boats cut big waves into the water that slowly radiated out to us. Nearer, the surface was not exactly smooth, but crinckled with lots of high frequency little waves. As the two waves combined, I was transfixed watching the resultant sum. I thought about WiFi and wondered if CCK modulation - which I've been reading about lately and is quite complicated - does something like waves on Jordan Lake. 

Gawd, I love waves.

The pink wave sums a deep, slow wave (blue) plus a small, fast wave (red).

Bummin' Around

I'm so over work on the real. My last day was Friday. Goodbye to AmeriCorps! It was a pleasure serving you, America - eliminating poverty and the like - but I must be goin' now. Well I'm on my way. I don't know where I'm going. I'm taking my time but I don't know where. I awoke early this morning before the sun had risen. A faint glow could be seen in the eastern sky and only the most brightest stars were still alight in the sky. I walked off the porch (where I'd been sleeping) and looked for the moon, but the moon had sunk too far west and was blocked by the neighbor's house (the same neighbor who keeps complaining to the city that our chicken coop is on their property). Chris, me roomie, told me of a lunar eclipse, but because the moon wasn't in view, I went back to the couch on the porch and lay down watching the dawn get on. Later in the morning, after I'd been to the bank and the post office to arrange for my impending trip - oh, did I m...

I know this is a long post, but if you break it up into two or three sections, it's a pretty managable read.

Boy, I must like blogging late at night because here it is midnight and I'm on the computer typing away. Keeping my roommates awake; the rucus of nimble little fingers on a particularly clicky keyboard. But, it's not particularly the night time blogging keeping me awake. I've just been having such a good time in the late night. Last night, for example, I made a cape from an old wool army blanket. It's a pretty neat thing. It's semicircle in shape with another smaller semicircle cut out for the neck. I made the neckhole too big, alas. But, I believe it's beautiful all the same. And, a mighty fine cape. I'll put a hood on that thing, then I'll be ready for the woods. Got my poncho (see Lost and Found ). Got my backpack (see Oh, I've been in a place ... ). Got my sleeping bag (see 'H' is for 'hairy' man ... ). Now I got my cape. I also got bugs on me right now! Some multitude of litte creepers. They bite like fleas. I had fleas once in h...

Iceland Day 4 - "Puffin' Up" or "Ditch the Van!"

By -
We camped under the waterfalls in part because it was close to the ferry to Vestmannaeyjar. We planned a quick out-and-back trip. The main point of the ride was to bird watch. Adam brought his zoom lens camera. In all we stayed out there only long enough to walk a few blocks. Then, we returned to the mainland and parted ways with plans to meet again in the morrow. On the way back to Reykjavík, we returned to the hot river. First we bought bread and coffee at a roadside bakery. Then, ate lunch at a park in the city as rain drizzled. Then, parked down the road from the trail head and started the long, sulfurous hike into the hills, with flies swarming is in the beginning. A reddish German Sheppard walked in front of us, and it’s owner (who called to the dog in German) said, “He likes you.” Finally we reached the river and lay down in a pool created by a stone wall. It was luxuriously warm. We returned the van after a quick stop by the rental apartment, where we met the owner and to...
