Pretty much says it all…

Just One More Slice…

cherrypieslice2

… and then I promise I’ll cut this out until next year!

Last year in the New York Times blog, John Tierney wrote about International Pi Day. (Which is, by the way, originally an invention of The Exploratorium in San Francisco.) He said:

The Exploratorium has gathered a few genres on its Pi Day site, including this limerick:

If inside a circle a line
Hits the center and goes spine to spine
And the line’s length is d
The circumference will be
d times 3.14159

These are his suggestions for writing your own odes to Pi:

You can write a traditional haiku about pi like this one:

Unending digits . . .
Why not keep it simple, like
Twenty-two sevenths?

Or, for the ambitious, you can try a pi-ku that’s both a haiku and a mnemonic device in which the number of characters in each word equals the value of the corresponding digit of pi. Here’s an example that enables you to derive 11 digits of pi (3.1415926535) by counting the number of characters in each of the 11 words:

Let C over D
(Wheel perimeter on height)
Equal its value.

Then, for the real purist, there’s a new form of pi-ku proposed by Ian Chillag of NPR: Instead of the 5-7-5 syllable pattern of haiku, honor pi with lines of 3, 1 and 4 syllables. Like:

Why is pi
Square
As pie is round?

Here is my own attempt at pi-ku, being silly and trying to make it erotic, of course — like my haiku.

Reciting
Pi,
math gets me hot.

I’m quitting now. Really.

More Pi, Please

This year Pi Day sort of snuck up on me. I think that next year I’ll have to create a blog carnival or something. There’s just infinite potential!

I love this cartoon about Pi Approximation Day (July 22). pi_day_dinosaurs

Call me obsessed. I’ve always had a thing for certain numbers, especially what are called the “master numbers” in numerology. I love 11, 22, 33, and 44. My birthday is in master numbers (11/22) and I frequently see them on clocks. For example, I’ll wake up during the night and it will be 3:33, or I’ll check the time at work and it will be 11:22. This has driven some of the people in my life crazy (or at least they thought I was crazy), but other friends say they now see it too, and frequently report my emails arriving with the time 11:22 on them. One friend called last year on my birthday to say she had just bought lunch and the tab was $11.22 and she knew she should call me!

I thought we were on to a great thing when an ex-girlfriend and I had our first date on 9/9/2007, which, of course, is all nines (2007 adds up to nine), and nines have their own special kind of magic. For starters, if you add up the integers in any multiple of nine (what’s called the digital root), you’ll get nine. Try it with the date 9/9/2007, which is really 3×9 or 27, which is again, (2+7), 9. I love it! Here’s some more fun information on nine.

As for Pi. I think I’m a little obsessed. I’m using memorization as a daily meditation exercise, as part of my other yoga practices. I’m up to about 50 decimal points. Who knows where I’ll be next year at 3/14?

P.S. Here’s a link to one of my short stories about Pi.

P.P.S. I just discovered there’s a world ranking list for memorizing Pi. Chao Lu of China tops the list with a world record memorization of 67,890 digits. It took him 24 hours and 4 minutes to recite it! Hell, I’ll be happy if I can get to 100!

Celebrate International Pi Day

Today, 3/14, is International Pi Day and just to prove my geeky worthiness, I’ll write it as far as I can from memory: 3.1415926535897932384626433.

I think that’s correct, but I’m not usually in this good form. However, I helped my son study for a Pi reciting contest his school held yesterday and some of it seemed to stick!

Oh, So Cute! Mandelbrot Bear

If I was going to pick out a plushy to keep my big-brained and oh-so-sexy sweetheart warm in my absence, this would be the one. This fractal teddy bear is named Mandelbrot and was designed by the crafty blogger at Buttons for Mouse.

Those of you who didn’t read James Gleick‘s Chaos: Making a New Science, can bone up on Benoit Mandlebrot and his sets here.

M. Eric Carr at Northlight Computing made this short film Mandlebrot Zoom, featuring the song “Mandlebrot Sets” by Johnathan Coulton. You’ve got to love a song that contains the line “you’re one bad-assed fucking fractal”.

(Baby, I hope you’re out there listening tonight… I’m dedicating this one to you!)

Well, hell. If this isn’t geek porn, I don’t know what is.

These oddly sexy pole-dancing robots are the creation of 20-year-old mechanical artist Giles Walker. They’re part of a London exhibit called “Mutate Britian“:

What Will You Do With Your Extra Second?

It will take a little longer for the ball to drop in Times Square this year.

The official Keepers of Time will add a leap second to the world’s master clocks (in the U.S., that’s the U.S. Naval Observatory) on December 31 at 23:59:59 UTC.

(I’m hoping someone will kiss me at 23:59:60!)

This extra second is necessary because official time depends on two timescales—one that uses atomic clocks and another that is dependent on the earth’s rotation—and they don’t match up perfectly. Plus, time is slowing down.

However, if time is still moving too fast for you, check out this video of the Corpus Clock, what the inventor calls a “chronophage” or “time-eater”. It’s hypnotic.

Female Scientists: Make Dr. Who a Her

Following Lord David Tennant’s recent announcement that would be leaving the British science fiction show Dr. Who after five special episodes set to air over the next two years, a group of women scientists has requested that the next Dr. Who be a woman.

Speculation over who will be Tennant’s successor has been rampant and now a group working to improve the numbers, and status, of women working in the science and technology fields have launched a campaign to make the next Doctor female.

A spokeswoman from the UK Resource Centre for Women in Science, Engineering and Technology (UKRC) said: “There is a distinct lack of role models of female scientists in the media and recent research shows that this contributes to the under-representation of women in the field.

“The UKRC believes that making a high profile sci-fi character with a following like Doctor Who female would help to raise the profile of women in science and bring the issue of the important contribution women can and should make to science in the public domain.”

Like any good, modern campaign, this one is up and running on Facebook.

Transsexual Gene Link Identified

Australian researchers claim to have found a genetic link that predisposes individuals to male-to-female transsexualiam.

Personally, I hope we don’t spend so much time studying the possibility and probability of everone’s individual quirks to the extent that we take all the fun out of it. After all, that’s what a lifetime’s for, right? I don’t want to be trapped on a tour bus with everyone around me on a pre-scheduled ticket. I want surprises!

Nevertheless, here’s the story, courtesy of the BBC.

Banjo Playing During Brain Surgery

If you’re as fascinated with the intricacies of the human body as I am, you might find this video fascinating.

Suffering from a tremor in his right hand, banjo player Eddie Adcock underwent brain surgery. Surgeons placed deep brain stimulating electrodes in his brain in an attempt to control the tremor.

Because surgeons need to be able to see the effects of brain stimulation, patients are kept awake – with anesthesia for pain control – during this type of surgery.

In this case, Adcock played the banjo. You can read more on the website he keeps with his wife Martha.

Ultimate Maverick – The Extreme Drinking Game

For decades, journalists on campaign tours with politicians have entertained themselves by counting the times a politician says certain words in her or his speeches. After having heard the same public addresses dozens of times (and being given the text ahead of time), word counting offers the note-taking folks an opportunity to stay semi-focused and look busy. Words like “freedom,” “American,” and “Pork-barrel” might all be considered countable.

Of course, in this election, that journalistic tradition morphed into the “maverick” drinking game.

With lots of folks having nursed Maverick Hangovers, I hope we’re all clear now that the word means an individual that breaks away from the crowd onto his or her own path, but doesn’t imply it’s a better path, or a path anyone else would want to follow, right?

Maverick is not synonymous with “leader”.

That said, the NT Times recently featured a bio of James Pennebaker, a scientist who counts words. Among lots of other projects, he’s been counting words in the presidential campaign.

Now this could be the basis for Ultimate Maverick, the Extreme Drinking Game. If you drew the category “death” and the candidate John McCain, for example, and had to drink every time he mentioned death or dying, you’d be twice as intoxicated as the person drinking in the same category for Obama.

Obama supporters would drink more frequently when work was mentioned, words such “job” or “paycheck,” for example. Obama supporters would be drinking McCain supporters under the table on the subject of acheivement.

Read all of Pennebaker’s  results here, on his www.wordwatchers.com blog.

(One spoiler: Obama uses bigger words more frequently. My own conclusion: His supporters are more likely to understand them!)

Back to the Future

The geekiest of the science/science fiction blogs say that the Chinese are reporting the invention of an “impossible drive” . The device is said to turn electrical impulses into microwaves, which in turn create thrust.

I think it looks suspiciously like a flux capacitor. You could stand it on end and throw the garbage right into the funnel. Where’s John DeLorean now that I need him?

Approximately Math

I’ve always wondered how I managed to score equally well in the math and English portions of my SATs all those years ago. The question has haunted me, popping into my head now and then. Considering my poor math record in high school, it always seemed… well… improbable that I would score even moderately in math, let alone well.

We think of mathematics as only a learned skill, but new research is showing that some kinds of math may be instinctive. You can read about “approximate number sense” here in the NY Times. On the NYT page, there’s also a fun test you can take, measuring your ability to quickly approximate numbers. The test information says that the average score for adults, in estimating 30 sets, is 75% accuracy. I took the test today, and in 40 sets I was 90% accurate.

So I think I finally have the answer to my SAT mystery: My approximate math skills are good, even if my learned math skills are lacking. Maybe this is why my friends are always asking me to calculate the tip!

Feel The Music

Set your ear buds aside: There are new ways to hear and feel your music.

You see, we have two ways of hearing. In simple terms, one method is the result of sound waves being sensed by our ear drums. The other method is conductive – the sensors in our hearing system pick up on vibrations in our bone, primarily our skull.

Two companies are making alternative ways of listening to your iPod though conductive hearing. One of the new headsets conducts sound through the bones of your skull, another through the cartilage of your outer ear. Read more about both of these methods in a story in the NY Times.

But if that’s not enough to set you abuzz, consider investing in the OhMiBod, a music-powered vibrating sex toy that will sync your personal rhythms to your iPod.

I couldn’t make this up. Really.

MacArthur Grants Announced

It’s always interesting to see who the MacArthur Foundation has chosen for it’s crop of $500,000 grants. These grants can’t be applied or lobbied for. Often called “genius grants,” they award excellence, promise, and innovation, and are usually a surprise to the recipients. (That’s a phone call that would make my morning!) Read about this year’s recepients here.

Collider in the Shop for Repairs

Launched on Sept. 10, the Hadron Super Collider has been out for a test drive. And, apparently it’s already got a few scratches and dings; it’s in the shop for at least two months. It might be longer than that… you know how long it can take to get parts for these fancy European machines. Read the full story here.

It’s a Mac, Mac World

Somewhere in my basement there’s a Mac Plus gathering dust. So you can understand why I think this is so funny: Analysis of the metadata of the photos on Microsoft’s “I’m A PC” website shows that they were created on a Mac. Read more here.
