In Honor of Pi Day: Deriving Pi from a Pie


Yesterday was Pi Day (and I intended to write this last night, but overslept in my evening nap), the day on which the abbreviation for the date (3/14) consists of the first three digits of pi (3.14).  And yesterday was a very special Pi Day, on which the abbreviation for the date including the year (3/14/15) consisted of the first five digits of pi (3.1415).

Some people like to incorporate pie (the pastry) into the celebration of Pi Day.  I think that if you include pie in your Pi Day, before you eat the pie, you should do the following:

1. Get a tape measure, and measure the circumference of the pie. 

2. Measure the diameter of the pie. 

3. Divide the circumference by the diameter.  

Thus you will have derived pi from a pie.  

(I imagine that I am not the first person to think of deriving pi from a pie, but it makes me feel clever, so I am putting the idea on my blog.)

I tried this exercise myself to see how well it works.  I didn't have a pie, but I measured a roughly pie-sized circular plate.  I got 3.11, which is within about 1% of the correct value.

Potential Sign of the Apocalypse: The Rap Version of "Money for Nothing"


I have learned that there is a new rap version of one of my favorite songs, "Money for Nothing", originally recorded by my favorite band, Dire Straits.  The new version was featured on a show called Empire which I have never watched.



The song is performed by "Jussie Smollett" and "Yazz".  Jussie Smollett is an actor on the show, but I'm having trouble figuring out who "Yazz" is.  It's not the band Yaz that recorded the song "Situation" back in the Dire Straits era, nor, as far as I can tell, is it this other Yazz.  

The original "Money for Nothing" was perhaps the ultimate mainstream rock song of the Eighties.  It was also a huge pop hit, spending three weeks at number one on the Billboard Hot 100.  From a modern perspective it seems impossible that a song with such a bone-crushing guitar riff could top the same chart now controlled by acts like One Direction and Selena Gomez. 

This new recording bears only limited resemblance to the original masterpiece.  The chorus is there, and some of the original guitar part shows up, but most of the song is unrelated rapping.

I Am Envious of New England


I am envious of eastern New England, which this week experienced a huge snow storm.  As usual, the Washington area, where I am, received under an inch.  

I would like the Washington area to have a giant blizzard.

I would also like the Washington area to have a giant lizard. 

But the giant lizard should wait for the summer, because I wouldn't want the lizard to get too cold.

In the News: Slash Is a Big Fan of the Tuatara


  Perhaps it shouldn't come as a surprise, but Slash is a big fan of the tuatara. And I don't mean the band of that name, but the actual rhynchocephalian reptile:
    If your name is Hendrix and you're a Hamilton-dwelling tuatara, a rock and roll legend would like to meet you.
    Slash, the former lead guitarist with 1980s/90s band Guns N' Roses, said he'd like to meet the city's resident tuatara when he's in town next month for his Claudelands show, alongside his band Myles Kennedy and the Conspirators.

The New Pink Floyd Album


I don't normally review music on this blog.  I am big music fan, but not a fan of reviews, because opinions about music are entirely subjective, and why is one subjective opinion any better or more useful than any other?  (And, perhaps more importantly, there isn't much music being released these days that I like.)  

I am making an exception, though, because Pink Floyd has released a new (and final) album, and Pink Floyd is one of my top three all-time favorite bands.  

The Endless River consists largely of tracks composed and recorded with late keyboardist Richard Wright during the sessions for their previous album, 1994's The Division Bell.  New material was added by guitarist David Gilmour and drummer Nick Mason. (In case you're not up on current events, I'll inform you that bassist Roger Waters has not been involved with the band since the early Eighties, with the exception of one brief reunion performance.)

The Endless River is not as good as classic Floyd from the Seventies, but it is a very good album. In places I find the music to evoke the sounds of Wish You Were Here and Meddle, as well as David Gilmour's first solo effort. But my biggest impression is that, being almost entirely instrumental, and largely ambient, the album doesn't so much sound like Pink Floyd as it does the ghost of Pink Floyd, haunting some abandoned London recording studio late at night.

And, beyond this, I can't help thinking that, in our current horrible world of Sam Smith, Meghan Trainor, Nicki Minaj, and Justin Bieber, The Endless River might just be the ghost of good music in general. 

In Reference to My Earlier Parks and Recreation Question . . .


In reference to my earlier Parks and Recreation question, the next/final season of the show will in fact be set in the year 2017, at least according to the ad for the new season that I've been seeing on NBC.

Five Questions About The Hunger Games


Since the premiere of The Hunger Games: Mockingjay—Part 1 a few weeks ago, I've developed some questions about the series.  (I could probably answer these questions by reading the books, or watching the movies, or just doing some internet searching, but I have no desire to read the books or watch the movies, and I am too lazy to do the internet searching.)

1. What is a mockingjay? Is it a mockingbird, or a blue jay (or some other kind of jay)?  Or is it some kind of bird that doesn't exist in our world, which would imply that the setting of The Hunger Games is an alternate universe which diverged from our own sometime after the evolution of anatomically modern Homo sapiens around 200,000 years ago, but still long enough ago to allow for the evolution of a novel species of songbird?

2. Why is everyone hungry? Since they live in an advanced technological society, shouldn't they know how to grow crops?  Did they lose the knowledge of how to plant corn?

3. Why is a brief period of gladiatorial combat between teenagers sufficient to distract an entire population from the fact that they're starving?

4. Why does everyone love Jennifer Lawrence so much?

5. What is a mockingjay?
