Pi Day at Caltech

In the latest manifestation of self-proclaimed Caltech nerd-dom, a group of undergrads strung a chain of 15,000 colored paper loops across the campus in honor of Pi day. There are nine colors, each one representing a number. The multicolor chain should be in order, representing the digits of Pi going 15,000 digits deep.

For the uninitiated, Pi is the digit that’s mostly often simplified to 3.14 (hence, March 14) and is used to calculate the circumference of a circle. The decimal can go out forever and mathematicians have figured it out to the 10 trillionth number so far.

Late Night Talk Show Tour

In case you wondered about the relative shortage of blog posts recently, it was because we were in southern California doing the talk show tour, among other things. For example, here we are on "The Tonight Show with Jay Leno":

Review: The Yellow Birds

Amazon

From The Yellow Birds: A Novel, by Kevin Powers:

We were not destined to survive. The fact is, we were not destined at all. The war would take what it could get. It was patient. It didn't care about objectives, or boundaries, whether you were loved by many or not at all. While I slept that summer, the war came to me in my dreams and showed me its sole purpose: to go on, only to go on. And I knew the war would have its way."

Review: Here's the Deal

Amazon

From Here's the Deal, by David Leonhardt:

Eventually, the country will have to confront the deficit we have, rather than the deficit we imagine. The one we imagine is a deficit caused by waste, fraud, abuse, foreign aid, oil industry subsidies and vague out-of-control spending. The one we have is caused by the world's highest health costs (by far), the world's largest military (by far), a Social Security program built when most people died by age 75 -- and, to pay for it all, the lowest tax rates in decades. The recent string of budget deadlines and crises may be manufactured. The problem is not."

S2L77: Taj Mahal

Agra, India
March 6, 1977

We toured the Taj Mahal by day, then returned at night to see it by the light of a full moon. I think I could have sat there all night and never gotten tired of the sight.

Remember that waxing moon I commented on while in Nepal? Well, by the time I reached Agra it was full. Perfect timing for a nighttime visit to the Taj Mahal. It's sometimes called the most beautiful building in the world. That won't get an argument from me.
