Hobbies


This is my newest hobby, starting from scratch in late 2016, and now fencing regularly at the West Berkeley Fencing Club. This is a superb sport that is very safe, an excellent workout, and technically challenging. Plus you learn a bit of French as you go along. En garde!

Here is a friendly bout at our club's holiday party in 2017. I'm in the left foreground fencing against a 15-year old girl who trains with the U.S.A. national team led by Olympic coach Greg Massialas. She regularly bouts with Olympian Alexander Massialas and is on her way to becoming an Olympian herself. Someone warned me that I would lose quickly but I was fortunate—I had just studied an effective counter-attack and won. Exposing my right shoulder invites her attack, at which point I duck, her blade passes over my shoulder, and I score with a counter-attack to the exposed lower part of her torso.



I swim 2-3 times a week at the Soda Aquatic Center in Moraga and enjoy open-water swimming over the summer.

Off the coast of Sardinia, the dolphins are clearly teasing me by swimming slowly (for them) and always out of reach.



Using a GPS in a waterproof pouch, I practice marine navigation using distal landmarks, the Sun, and idiothetic cues. Here the shortest course (a straight line) to cross this bay in Crete is 475 meters. The starting point is at the upper right. Swimming to the lower left my path (top line) measures 490 meters. Pretty good! However, on the return leg (bottom line) the path is 500 meters. The lesson learned is that when swimming into the prevailing weather (coming from open sea on the right) I over-compensated on my bearing. It was the correct decision to swim into the oncoming waves, but these were not as strong as I perceived and I travelled in a windward arc that wasted 25 meters. This five percent error on a five kilometer swim would add a whopping 250 meters or 3.5 minutes to a course.


For most of the year I swim here, the Soda Aquatic Center, which is also the training pool for USA Synchro (the duet team is shown here). My best strokes are free and fly, so for an hour workout I'll try to squeeze in 2000 free and 500 fly in different combinations against the clock. For example, a 20-minute set might be five 100's+50 kick on a four minute interval, where the 100's are in the order 100 fly, 75/25 fly/free, 50/50 fly/free, 25/75 fly/free, 100 free. The 50 kick allows the arms to rest from the fly, and the progressive reduction of fly allows enough recovery for the entire set to repeat from the beginning -- two sets add to 500 fly. If you want to swim only free, you can substitute a maximum effort free for each fly.



Everyone seems to be kiteboarding nowadays, and I've taken lessons, but I guess I'm sticking to windsurfing. It's more of a hassle, I admit it, I've even broken my ribs, twice, but windsurfing has moments when the board and the sail, the wave and the wind, are all channeled by the person into a magical kinetic harmony, without even thinking. Or, if the wind goes nuclear, just go as fast and as high as possible until something breaks.

I've been studying classical and flamenco guitar since college, and have performance experience in both flamenco guitar and dance. Because flamenco is improvisational, playing for a dancer can be a pure thrill as both guitarist and dancer spontaneously and instantaneously connect their emerging creative energy into a unique performance.

Screenshot from a Spanish language cable show (ahem, that young guy is me). I performed with Mosaico Espanol in the 1990's at events on Oahu and Maui.


El Cabrero (left) and Pepe Habichuela (right) are the real deal. I'll never forget their outdoor summer performance together at 2 a.m. in Andalucia.



I am a member of CAIFF (California Independent Film Festival) and have enrolled in different courses and workshops since college. In general, I prefer films that have hidden meaning in the visual content and spoken narrative, especially if it questions the nature of reality, identity and purpose. Though "The Matrix" and "Dark City" comes to mind, there are many others such as "Barton Fink" and "A Serious Man" by the Coen brothers, or Miyazaki's animated "Howl's Moving Castle."

I attended several workshops by the late film critic Roger Ebert. We would go scene-by-scene through various films, analyzing the large variety of elements that convey meaning on screen.



I enjoy slow running in mindless circles around this rubberized track for 10 kilometers or 60 minutes, twice a week. Running on such tracks minimizes the risk of injury, and at the same time allows the mind to relax and wander, which serves to consolidate memories and evoke novel problem-solving. The breakthrough ideas period usually starts 20 minutes into the run because mind-wandering is enabled when: 1. novelty in the immediate environment has subsided from attention, 2. increasing physical exertion triggers a natural defense response of separating the mind from the present and from the body, and 3. motion through space activates hippocampal place cells and entorhinal grid cells which are associated with the basic architecture of memory and semantic knowledge.

I also carry an iPhone during Human Hamster Running for music and for dictating notes as new ideas come to mind. The only danger is an abnormal craving for corn and sunflower seeds.



I almost forgot to mention that astronomy has been my hobby since I was 12 years old. I still have my original telescope, a Dynamax 8-inch Schmidt-Cassegrain.
