Fibonacci sequence hidden in ordinary division problemJUL 06

If you divide 1 by 999,999,999,999,999,999,999,998,999,999,999,999,999,999,999,999 (that's 999 quattuordecillion btw), the Fibonacci sequence neatly pops out. MATH FTW!

Fibonacci division

At the end of Carl Sagan's Contact (spoilers!), the aliens give Ellie a hint about something hidden deep in the digits of π. After a long search, a circle made from a sequence of 1s and 0s is found, providing evidence that intelligence was built into the fabric of the Universe. I don't know if this Fibonacci division thing is on quite the same level, but it might bake your noodle if you think about it too hard. (via @stevenstrogatz)

Update: From svat at Hacker News, an explanation of the magic behind the math.

It's actually easier to understand if you work backwards and arrive at the expression yourself, by asking yourself: "If I wanted the number that starts like 0.0...000 0...001 0...001 0...002 0...003 0...005 0...008 ... (with each block being 24 digits long), how would I express that number?"

I can't believe it's not newspaperJUL 06

Randall Rosenthal makes amazingly realistic wooden sculptures of everyday objects like newspapers, legal pads, baseball cards, and kitchen scenes. He carves each of his sculptures out of a single block of wood. So, this is carved entirely out of wood:

And so is this:

Books in the films of Wes AndersonJUL 06

Books loom large in Wes Anderson's movies. Several of his films open with opening books and Fantastic Mr. Fox is based on an actual book. Here's a nicely edited selection of bookish moments from Anderson's films.

In the work of Wes Anderson, books and art in general have a strong connection with memory. The Royal Tenenbaums (2001) begins with a homonymous book, as does Fantastic Mr. Fox (2009). The Grand Budapest Hotel (2014) begins and ends with a book. Moonrise Kingdom (2012) ends with a painting of a place which no longer exists. These movies have a clear message: books preserve stories, for they exist within them and live on through them.

What was the Venus de Milo doing with her arms?JUL 03

The Venus de Milo's arms are lost to history but that hasn't stopped historians and scholars wondering what exactly she was doing with them when the statue was carved. In order to test out a theory that Venus was spinning thread, Virginia Postrel hired designer and artist Cosmo Wenman to construct a 3D model of Venus de Milo.

A guide to Don DeLillo's booksJUL 03

This list ranking Don DeLillo's novels into categories ranging from "Classic" to "Avoid" from 2007 excludes his two most recent novels, but if you have little exposure to the author, it's a good place to start.

White Noise. DeLillo's breakthrough success, arguably still his quintessential masterpiece, and the funniest and most sustained example of his talent. Jack Gladney, professor of Hitler Studies, struggles with information overload, simulated disasters, an "airborne toxic event," the most photographed barn in America, and a drug that neutralizes the fear of death. If you're going to like DeLillo, this is the book that will make it happen.

Confession: aside from attempting to tackle Underworld1 more than 10 years ago, I have not read any DeLillo. I should probably fix that? (via @davidgrann)

  1. I bought my copy of Underworld at a San Francisco used book store at the same time I bought Infinite Jest. Like I said, Underworld didn't do it for me, but reading IJ became an odd sort of turning point in my life.

How people respond to life-changing inventionsJUL 02

Near the end of a piece by Morgan Housel called Innovation Isn't Dead, appears "the typical path of how people respond to life-changing inventions":

1. I've never heard of it.
2. I've heard of it but don't understand it.
3. I understand it, but I don't see how it's useful.
4. I see how it could be fun for rich people, but not me.
5. I use it, but it's just a toy.
6. It's becoming more useful for me.
7. I use it all the time.
8. I could not imagine life without it.
9. Seriously, people lived without it?

That's about right. I can only recall a couple of instances where I've skipped from step 1 to step 8 or 9: when I first used the Web1 and when Jobs introduced the iPhone at MacWorld. Everything else -- Google, HD TV, Twitter, personal computers, streaming music services, wifi, laptops, Instagram, mobile phones -- went through most of the 9 phases. (via @cdixon)

  1. Not the Internet, the Web. I used the Internet before I used the Web (Usenet, FTP, and Gopher mostly) and I never got the "OMG this is going to change everything" vibe I got after using the Web for five minutes.

Compasses don't work on Mars, so how do you navigate?JUL 02

Unlike the Earth, Mars and the Moon don't have strong directional magnetic fields, which means traditional compasses don't work. So how did the Apollo rovers and current Mars rovers navigate their way around? By using manually set directional gyroscope and wheel odometers.

While current un-crewed rovers don't have to return to the comfort of a lunar module, some aspects of the Apollo systems live on in their design. Four U.S. Martian rovers have used wheel odometers that account for slippage to calculate distance traveled. They've also employed gyroscopes (in the form of an inertial measurement units) to determine heading and pitch/roll information.

One of the fun things about reading The Martian is you get to learn a little bit about this sort of thing. Here's a passage about navigation on Mars where astronaut Mark Watney is trying to get to a landmark several days' drive away.

Navigation is tricky.

The Hab's nav beacon only reaches 40 kilometers, so it's useless to me out here. I knew that'd be an issue when I was planning this little road trip, so I came up with a brilliant plan that didn't work.

The computer has detailed maps, so I figured I could navigate by landmarks. I was wrong. Turns out you can't navigate by landmarks if you can't find any god damned landmarks.

Our landing site is at the delta of a long-gone river . NASA chose it because if there are any microscopic fossils to be had, it's a good place to look. Also, the water would have dragged rock and soil samples from thousands of kilometers away. With some digging, we could get a broad geological history.

That's great for science, but it means the Hab's in a featureless wasteland.

I considered making a compass. The rover has plenty of electricity, and the med kit has a needle. Only one problem: Mars doesn't have a magnetic field.

So I navigate by Phobos. It whips around Mars so fast it actually rises and sets twice a day, running west to east. It isn't the most accurate system, but it works.

I wonder why the rovers in the story weren't outfitted with directional gyroscopes and wheel odometers? (See also the operations manual for the lunar rovers.) (via @JaredCrookston)

How do bikes ride themselves?JUL 01

Here's something that I knew as a kid but had forgotten about: if you get a bike going on its own at sufficient speed, it will essentially ride itself. MinutePhysics investigates why that happens.

Interesting that the bike seems to do much of the work of staying upright when it seems like the rider is the thing that makes it work. (via devour)

Letters to your younger selfJUL 01

Tennis great Pete Sampras recently wrote a letter to his 16-year-old self.

There's more to being a pro than just playing tennis. The more successful you are, the more people will want out of you. It won't always be something you'll want to do, and it won't always be fun. The pressure will be as exhausting as anything you'll ever do on the tennis court. But as a tennis champion, you have that responsibility. You play tennis because you love the game, not because you love the limelight, so get ready. Think about getting some media training. It'll go a long way. Luckily, you'll be out of the game before these things called Twitter and Facebook come around. Be thankful for that. One day you'll understand what I mean.

Oh, and put the newspaper down. Don't read what people are saying about you. No good can come of it. And if you do hear or read something negative about yourself, don't sweat it. Let your racket do the talking.

There's nothing that distinguishes Sampras' letter from others of the format, but it got me wondering if these letters from successful people to their younger selves would have the hoped-for impact. It seems to me that success requires struggle, failure, and a bit of stupidity...or if you want to be nice about it, a beginner's mind. Skipping even some of that might take some of the edge off. Perhaps Sampras should write another letter to his 15-year-old self urging him to ignore any subsequent correspondence.
