One reason you don't want me for president.

I spent the weekend in Pasadena CA in a conference on quantum information at Caltech. It was a blast. I was kind of in charge of our little caravan and I paid all the gas bills for our van. The total was $192 for gas going there and back. It took us about 11 hours each way not including breaks.

On the way when I wasn't driving I was finishing "Let my people go surfing" by Yvon Chouinard. He founded and grew Patagonia kind of by accident and ended up making it a company with a mission. The mission is to slow down the destruction of the earth. I loved the book.

Anyway, Gina and I decided to become conscious of how much we use of different resources like electricity, gas, gasoline, water, and so on. Over the years we hope we can find ways to cut our use of each one in a reasonable fashion.

But that and our van dying yesterday morning got me thinking. Our life here in Albuquerque would be nearly impossible without our cars. Stores are all miles away. School is far away. Public transportation is slow, rare, and inconvenient. Biking around town turns out to be quite dangerous because of the way the roads have been made and the way cars drive. The whole thing is a waste.

I know what I would do about it if I were in a position to act. I would start hiking taxes on all products based on fossile fuels. I would do it now, but in a small way. I would increase taxes by 3% each month and I would keep up that policy of increases for the next several years. All proceeds from the tax would go toward building infrastructure for mass transit solutions and bike trails. In other words I would systematically and gradually make mass transit cheaper and safer and individual motorized transit more expensive and let people adjust their lifestyles accordingly. I'd like to think that perhaps within 10 years of such a policy the Salt Lake Valley would stop filling up with crap every winter . . .

Special Relativity

I wrote the first chapter of a text book on Special Relativity. I think I might call the text "Special Relativity in your bones" because the goal will be not so much to learn about it academically as to have it become a part of the way you think about the world. By the end of the textbook you should be able to hear that a bullet moves at x miles per hour and calculate in your head the length contraction and time dilation associated with that bullet. And you should know how to mentally rotate time into space and vice verse as you think hop from one special referrence frame to another. You should be able to derive the whole theory from the premise that the speed of light is a law of physics.

It assumes high school math and has been fun to write. It's modeled on the Saxon math textbook series. Anyway, since beginning I have found out that writing the thing is going to be a bit of a recursive process. If you want to read through the first chapter let me know. I'd love feedback.

I'll add a comment to this post when I get to a finishing point on any given unit. Currently finishing such an incremental part of the book consists of the following tasks:
  • I've written the explanatory section
  • I've written up the problems (20 to 30)
  • I've written up the solutions
  • I've found and included an appropriate quote
  • I have the content outlined for the next 5 units
  • I've taken into account any feedback that I've received on previous units.

8 minutes and 47 seconds

It's been (plenty below) freezing here in the mornings so I've been putting this off for a bit. But this morning I went outside with my GPS and walked over to a little trail about .2 miles from our home. After walking on the trail for another .2 or so miles I reset the GPS odometer and started jogging. I wanted a benchmark time so I tried to jog at a reasonable pace and then just keep running until I had gone a mile. Anyway, it took me 8 minutes and 47 seconds. It was cold enough that my throat was hurting by the time I was done. And I notice that my calves are a little sore now so I'm clearly not in running shape. We'll see how much I improve on that over the course of the year.

Did I mention that due to a lot of scrambling by my friends up at LANL I am funded through the summer? That means awesome insurance for this next baby. Very nice.

I'm going to use comments on this post to keep track of my 1-mile times. We'll see how it goes.
