Halfway to France (and Back) 
  Last month, I told you about biking halfway to Mexico. Yesterday, I had the pleasure of biking halfway to France. I borrowed a bike from Lausanne's free bike rental program and headed along the lake to Vevey, about 10-12 miles away. It looks like if I had continued around the circumference of the lake, another 10-12 miles would have put me in... more »

In Search of the Northwest Passage 
  I've been trying to find a good bike shortcut to Takoma Park and Silver Spring. Driving, we have a more-or-less straight shot up East-West Highway, but that isn't suitable for driving. And once I get close, the Sligo Creek Trail and various on-road bike routes make things easy. But it's tricky handling the distance between home and where the East-West... more »

Google Books, genealogy and the Metcalfs 
  I was reading an article about Google scanning books and putting them on-line, and I decided to see if I could use some of these books to help me with genealogy research. I found out that one of the books scanned was "Metcalf Genealogy", published in 1898. As it turns out, my great-great-great aunt married a Metcalf...... more »

Grantham's Problem 
  (Cross-posted from my math blog, which I'm pretty sure nobody reads.) While reviewing the referee's 44 (sigh) suggested changes to my paper, I came across an article published last November entitled "Inefficacious Conditions of the Frobenius Primality Test and Grantham's Problem". I have a problem named after me!... more »

Biking Santa Barbara 
  I rented a bike when I was in Santa Barbara for a conference earlier this month. I got in over 80 miles of biking in 4 days, so it was more than I'm used to doing. One day I did 27.9 miles, a personal best (and an exhausting one). The weather was cool, the terrain was flat, and the bike paths were well marked -- all conducive to lots of riding. Two of... more »

Halfway to Mexico (and Back) 
  For Christina's birthday, we drove the bikes down to Coronado and rode down to Silver Strand State Beach. When I looked at the satellite view of the trip, I realized that the ride had covered about half the distance from Coronado to Mexico (hence the title of the post). The ride is really beautiful, with San Diego Bay on one side and the... more »

Bike To Work 
  On Monday, we drove down to Coronado and rented bikes. On Tuesday, I biked to work, following the above path. It's a lot easier in California, what with the bike lanes and such. I also biked to work on substantially the same path the following two days -- I'm not going to record any more trips to work unless I take a different way. I have one... more »

3 recent bike trips 
  I've had three more bike rides in the past week. Last weekend, I took another trip to Silver Spring (light blue path). On the way there, I tried a partial shortcut. While the full shortcut will undoubtedly save 1.5-2 miles, the partial shortcut was longer. On the way back, I went the "long" way and didn't get lost, and it was... more »

Early July Biking 
  I like the above map as a way of summarizing a bunch of bike rides at once. I've continued logging my trips at Everytrail; links below. - On the 2nd, we rode to the bike shop and back (light red path). On the way, I popped a tire, which led me to get nice new tires on my bike. - On the 4th, I inadvertently rode to Silver Spring (light green path).... more »
