There's Not Enough iPhones to Circle the Earth

-
Piper Jaffray's senior analyst Gene Munster thinks it's going to be a good weekend for Apple as companies in 8 countries roll out the iPhone 3G S today. Yet will it be good enough?

Analysts expect half a million units will be sold today. That's a fine mess of finger-sliding real estate (actually about half an acre of touch screen mess-ness), but hardly enough to have any kind of global impact - at least not in a strictly geospatial sense. How many iPhones has Apple sold? How many iPhones would it take to circle the earth? Clearly these are VERY IMPORTANT questions! Well not really...but wouldn't you like to know?

The first iPhones were sold on June 29, 2007, and 3G sales started a year later on July 11, 2008. Today you can buy a 3G S. According to Aayush Arya (macworld.co.uk, 03/24/2009), Apple sold 13.7 million units in 2008, for a total of 17 million iPhones. Using data from Wikipedia by March 30, 2009 Apple had sold 21.17 million iPhones.



The iPhone measures 4.5 inches in height by 2.4 inches in width and by 0.48 inches thick, so 21.17 million iPhones, laid end-to-end would measure about 95 million inches, which works out to be 1503 miles. This figure depicts the range, or how far out from Apple headquarters in Cupertino, California you could go by laying all these iPhones end-to-end. It's a long way, but it won't reach around the world.



The trend for iPhone sales is positive, so using the data I wanted to find out when there would be enough iPhones to reach all the way around the world. With ZunZun, an online curve fitting resource, I was able to fit this data with a second order polynomial with good results (the model estimated that Apple would have sold a total of 2.7 million iPhones by March 30, compared to 2.2 million that were actually sold). Here's what the fitted curve looks like:



Along the X-axis are the number of days since the the iPhone was launched, and the Y-axis represents the total number of iPhones sold. Here are the estimated parameters for the 2nd order polynomial trend line:



With this information you can work out the estimated total number of iPhones sold at any given time. For example, by June 30, 2009 (the 732nd day since the iPhone launched) the model estimates that Apple will have sold a total of 2.76 million units. My guess is the number will be a little higher because of the hype associated with the 3G-S. Even so, consider that the Earth has a circumference of about 24,902 miles. So we're going to need 350,620,160 iPhones laid end-on-end just to get close. That's a lot of iPhones, right?

The model predicts that by the end of 2019 Apple will have sold more than 342 million iPhones, and the big day comes just a few weeks later. On January 16th, 2019, on the day that Ernest Shackleton discovered the magnetic South Pole, Apple will have sold enough iPhones to circumscribe the globe. In the meantime we'll just have to cool our jets, playing flightcontrol and waiting for the next update.

Visualizing with Wordle

I was playing around with Wordle this evening. "Wordle is a toy for generating “word clouds” from text that you provide. The clouds give greater prominence to words that appear more frequently in the source text. You can tweak your clouds with different fonts, layouts, and color schemes."

What I like about the web site is that one doesn't have to register to add content to the public gallery. Just type in your username when you submit a wordle.

I did five projects right away. The first was Lincoln's Gettysburg Address. This was followd by the abdication speech of King Edward VIII, Richard Nixon's resignation speech, and then two Hello World projects, one for ANSI-C and one in Assembler. By the way, I also created a wordle using the text of this blog post. Nifty, huh?

How many beans are in a pound of coffee

I'm intent on finding out. What got me interested in this was a recent TWIT podcast that highlighted Wolfram Alpha, which aims to "make all systematic knowledge immediately computable...", yet a search for How many coffee beans are in pound of coffee turned up nothing. So does anyone have any idea? My last "pound" of coffee (they sell 12 oz "pounds" at Starbucks) was pre-ground, so I'm going to have to wait until I have beans before I can start my research. I'm guessing that moisture content is important.

In the meantime...here's some anecdotal evidence from ground coffee to get things started: I measured a coffee scoop (2 TBS) of ground Starbucks Kenya and it weighed 9.5 grams - enough to make two cups of coffee. Now 9.5 grams is 0.335 ounces, and since there are 16 ounces in a pound (yes there are - don't interrupt me, SBUX), then there are 47.761 scoops in one pound. But we're talking Starbucks here...so that would be 35.8 scoops of coffee in a Starbucks "pound" - enough to make almost nine 8-cup pots of coffee.

St. Joseph Peninsula Beach - Winner of 2009 Best Restored Beach

One of the winners of ASBPA's 2009 Best Restored Beaches is St. Joseph Peninsula Beach. This 7.5 mile beach has also been designated one of the pet friendliest beaches in the nation, and the St. Joseph Peninsula State Park, located on Cape San Blas ranked first in America's Top Beaches 2002.

"The St. Joseph Peninsula Beach Restoration Project is located along the western portion of Gulf County, Fla. Over 250,000 people visit St. Joseph Peninsula each year and provide substantial economic benefits to the local economy. A key component of the project’s success was the support of the local community, who donated time and resources to make this project a reality. The project included beach restoration along 7.5 miles of coastline, including areas with critically eroded beaches. The project’s success is based on excellent sand quality and design, resulting in an enhanced recreational beach, increased storm protection and an extended habitat for marine life."

Top Designer

Di Anna Borders is one of my favorite designers because of her versatility. Previously a lead designer at a Fortune 500 company, she coordinated pattern and colors for wall coverings in most of the swankest hotels and resorts, from Texas to Dubai. In fact the background for this page is one of her own design. She is now a freelance artist and modern photo-savant and her photography and print work can be viewed at selected art festivals.

And her photography! Well, let's just say that it embraces the serenity of postmodern naturalism viewed from the perspective of a curious outsider looking ever outward: light and shadows - beauty, tempered with nuanced incomprehensibility. Through this vision she abstracts nature into a new contextualization of light and image.

Regional Bike Trails in the Deep South

Natchez Trace Parkway (20 miles west of Starkville, MS) is prime cycling for weekend metrics, and loaded touring. Amazingly, the entire length of the Parkway is designated as a bicycle tour route, and although there are no bike lanes, it doesn't really matter - most of the time you have the entire roadway to yourself. When there is traffic it's non-commercial only and 50 MPH. Natchez Trace Parkway

Longleaf Trace (196 miles southeast of Starkville, MS) is a 41 mile paved trail, and the longest rails-to-trails project in the South Central US. It runs from Prentiss to the University of Southern Mississippi campus in Hattiesburg. Longleaf Trace

Chief Ladiga (203 miles east of Starkville, MS) is a 33 mile (22 miles continuous paved) trail that extends from the north side of Anniston, Alabama to the Georgia State Line. There are plans to join it to the Silver Comet Trail in Georgia. The Talladega Mountains form a backdrop for any riding in this area. Chief Ladiga

Silver Comet (282 miles east of Starkville, MS) is a 60 mile (40 miles continuous paved) trail that runs from Smyrna, GA to just northwest of Atlanta. Highlights include crossing the Pumpkinvine Creek Trestle, a 750 foot long, 126 foot high bridge, and passing through the 800 foot Brushy Mountain tunnel. Silver Comet Trail

Tammany Trace (312 miles south of Starkville, MS) is a 31 mile paved trail just north of New Orleans. The highlight of the ride is Abita Springs Brew Pub: handcrafted beer and good southeast Louisiana seafood. Tammany Trace
