Rabies Post-bite Treatment


It seems like everyone in Buenos Aires who owns a dog and lives in an apartment has a dog walker to take their dogs out every day. You constantly see dog walkers in the street with 10 or 20 dogs, all on separate leashes, walking around perfectly happily. Many more dogs that would be considered safe or responsibile for dog walkers in the US.

How to dry a cast iron skillet

When you wash a cast iron skillet, you have to dry it or else it rusts.

Some people in my house like to dry the skillet with a dish towel. Usually this results in a dirty dish towel, and the towel goes in the hamper.

Some people in my house like to dry the skillet over a gas flame.

We have a dispute about which method is worse for the environment, and I am going to use the famous "n of 1" research method to resolve this dispute.


  • It takes 30 seconds to dry a burner over a gas range.

Parking Probability

I was parking at a metered spot today, and didn't have enough money to pay for the time I needed. But I figured it was probably worth paying for part of the time, to cut the chances of getting a ticket.

It would be great to create a parking calculator that would tell you when it was a good bet to pay the meter and when it was a good bet to risk a ticket.

You'd need to know

  • How long you will be parked
  • Hourly rate for the meter
  • Amount of the fine if you get a ticket
  • Probability of getting a ticket per hour parked

"I voted" for bad?

I was asked "how many cubic yards of "I Voted" stickers are going to wind up in landfills across the country" after this election?

And I decided to use powerful n=1 research techniques to answer the question.

The "I voted" sticker where I live is about 2 inches long.

It is about 0.01 of an inch thick max (cardstock is .0175, 16lb bond is .0032)

The REAL Carbon Footprint of Bicycles

Sure, everyone thinks that bikes are awesome because they get infinity miles to the gallon, but that's just hype!

There's absolutely a carbon footprint associated with bicycle use. From the manufacture and shipping of frames and accessories to the carbon footprint of the foods you eat that fuel your bike, it's clear that bike riding takes an incremental but measurable toll on the environment.

The real question is, "How does a bike's carbon footprint compare to a car's carbon footprint?"
