Are you the driver in the lot who parks in the first spot you see? Or do you circle around and around looking for a spot by the door? Physicists Paul Krapivsky of Boston University and Sidney Redner of the Santa Fe Institute explored the mathematics of parking. The research required different equations and simulations to model the benefits of the various parking approaches. From EurkeAlert!:
In their paper, Krapivsky and Redner map three simple parking strategies onto an idealized, single row parking lot. Drivers who grab the first space available follow what the authors call a "meek" strategy. They "waste no time looking for a parking spot," leaving spots near the entrance unfilled. Those who gamble on finding a space right next to the entrance are "optimistic." They drive all the way to the entrance, then backtrack to the closest vacancy. "Prudent" drivers take the middle path. They drive past the first available space, betting on the availability of at least one other space further in. When they find the closest space between cars, they take it. If no spaces exist between the furthest parked car and the entrance, prudent drivers backtrack to the space a meek driver would have claimed straightaway.
So which strategy is best? As the name suggests, the prudent strategy. Overall, it costs drivers the least amount of time, followed closely by the optimistic strategy. The meek strategy was "risibly inefficient," to quote the paper, as the many spaces it left empty created a lengthy walk to the entrance.
Oh, the joys of #vanlife! I was checking up on my Vanagon yesterday and noticed the coolant was low. Missing coolant is very bad in a Vanagon for many, many reasons. I looked for a leak. I could not find a leak. It was possible the car had just burped an air bubble and swallowed […]
Pennsylvania resident Chris Persic says his wife called to let him know their SUV smelled like it was burning. When she opened the hood, a surprise was waiting: walnuts and grass piled all over the Kia engine, stashed their by misbehaving squirrels.
I’m glad they didn’t wreck but the driver’s facial expressions in this clip are really something. He’s be a great character actor. The whole clip is like a scene from a Jim Jarmusch film.
Remember when the default state of your online presence was anonymity? That’s not so clear-cut anymore, and the worst part is you may not even know who is using your data or what they’re using it for. Small wonder that so many people are choosing to surf through virtual private networks. VPNs filter web access […]

There’s overwhelming support for clean energy, and the planet is giving us more reasons to invest in renewable power sources with every passing year. Even in the most inhospitable areas, wind and solar can provide a good chunk of our power, if not all of it. So why aren’t we all taking advantage of it? […]
