QotD: Gravity and Stillness

Gravity is the root of lightness;

stillness the ruler of movement.

Rowing 2: Advanced Beginner Status

The previous post about big water rowing strategy for small water boaters has been helpful to a lot of non-boatmen tasked with rowing.  Several friends have asked me to write another with more rowing skills to learn and practice.  In truth, it took me decades to get comfortable with the basics, most likely because I rowed only occasionally.  Really having control of my boat angle, and going for the meat got easier, but the finer points were lost on me.  I've ridden with boatmen who row every day for months and years on end, and been amazed at what they can do.  I've never rowed for a living, so I'm an amateur.  Still, I've had some seasons when I rowed enough that light bulbs went off in my head.  Here are a few of the lessons that made a big difference for me.

Speed of Light Restored to Supremacy

Remember those faster than light neutrinos? Great, now forget 'em. Science proved 'em, then unproved 'em.

New Favorite River: The Lower Wind

Of course my favorite river is always whichever one I'm on. Or was just on. Or am about to go on. Today was my third time down the Lower Wind in Washington, and it is quickly working its way into the list of all time favorites. It's not especially hard. Mostly class III with some IVish low volume rocky stuff, one hard class IV (V-?) called the Flume, and then the series of four drops at the end that most call class IV. The four large drops are 1) vertical 10 footer with an autoboof on the left 2) vertical 20 footer that I like to boof right 3) long bony slide, stupid, dangerous, but kinda fun, 4) the final 10 footer that is a clean (boof right) part of the otherwise rock-infested weir.


This is the autoboof at the first of the final series of falls.

Toroidal Bubbles

Made by dolphins, whales, people, volcanoes, nukes. Very interesting visuals, mostly camera footage, some explanatory graphics.

you can live as if nothing is a miracle;

Physics at the Community College

OK, to follow is the review for my comprehensive final exam in second-semester college physics. But first, a little background.

Physics Bitch

I can scarcely believe the tone and content of this so-called Physics class. I just escaped. The woman wanted us to devise a way of measuring the speed of light that was different from the method of Michelson, who actually did it in the late 1800's. Of course the technologies we were supposed to use were of that era. Michelson's method was ingenious and he was awarded the 1907 Nobel Prize for it. One cocky young man got up and drew pictures on the board the spewed a load of bull about how he would do it. Made no sense scientifically. No one else in the class had a feasible way of measuring lightspeed (not an easy thing to do) so she kept us in class telling us we were to turn in our method for next class, and to figure it out while sitting there until 8:30pm. She let the bullshitter and his "group" go early, and kept the rest of us to "work on it". I refuse to turn in a load of bull and pretend that it might work. She treats us like second graders and I can barely keep myself from telling her exactly what I think of her. I am going to LAMBAST her in the teacher evals at the end of the semester. I am tempted to go to the higherups of this school immediately to tell them about the class. Unfortunately the majority of the students will say "nice" things about her because she gives out good grades. This kind of "education" is for the birds.

Mood: furious.
