Globalizing the Nineteenth Century

Joseph L. Yannielli

This is cross-posted from the blog Digital Histories at Yale.

Nineteenth-century Americans viewed themselves through an international lens. Among the most important artifacts of this global consciousness is William Channing Woodbridge’s “Moral and Political Chart of the Inhabited World.” First published in 1821 and reproduced in various shapes and sizes in the decades prior to the Civil War, Woodbridge’s chart was a central and popular component of classroom instruction. I use it in my research and teaching. It forms a key part of my argument about the abolitionist encounter with Africa. And every time I look at it, I see something new or unexpected.
Chart of the Inhabited World:
Exhibiting the Prevailing
Religion, Form Of Government, 1821

Like basketball and jazz, the moral chart is an innovation unique to the United States. The earliest iterations depart from the Eurocentric and Atlantic focus with which modern readers are most familiar. Reflecting the early American obsession with westward expansion, they gaze out over the Pacific Ocean to East Asia and the Polynesian Islands. The chart features a plethora of statistical and critical data. Nations and territories are ranked according to their “Degrees of Civilisation,” form of government, and religion. Darker colored regions are “savage” or “barbarous” while rays of bright light pour out from the Eastern United States and Northern Europe.

Why History Students Should Love Big Data

Eric Schultz

Spring 1976. Wilson Hall, Brown University. The late, great Professor William McLoughlin has just informed his 85 students in “American Social and Intellectual History” that they are to write their first paper. All he has given us is the title: “The Age of Jefferson and Adams.” We groan. Then he adds: “Keep it to three pages or less. Double-spaced.” We smile. Three pages? How hard can that be?

“If you make the margins too wide,” McLoughlin adds, “I’ll mark you down a grade.”

Needless to say, nobody got an A on that paper, or so the good professor informed us. There may have been a B or two. Not me. It was all I could do to contain my flowery opening paragraph to a single page. Some of us recovered slightly in round two, wherein we committed “The Age of Lincoln and Calhoun” to three, double-spaced pages. Some retreated to organic chemistry and other more reasonable challenges.

Little did I know, but I had just been introduced to Big Data—though it would take 35 years to earn that name. Take an endless, insurmountable, seemingly disconnected pile of information, separate the grain from the chaff (or, as my engineering buddies would say, the signal from the noise), and tell a concise, compelling story about what it all means.

BioShock Infinite and Creative Anachronism

Randall Stephens

A screen capture from BioShock Infinite (Irrational Games, 2013)
I'm not proud to admit it . . . Sometimes I play video games.  And, no, I don't live in my mother's basement with black-light posters on the walls.  I don't subsist on Cheez Puffs, Slim Jims, and Mountain Dew. I have a job. I have a life.

Confession over.  

For non-gamers (lots of people), I'd like to say a little about a fun game that draws creatively off the past.

BioShock, which rolled out in 2007, was set in a disturbingly macabre, underwater, Ayn Randian dystopia. (Shooting libertarian fish in a barrel?) The submerged city, populated by psychopathic surgeons, genetically altered loonies, and a raft of creepy grotesqueries, is the gamer's playground, where she/he looks for clues and tries to set things right. Calamitous fun all around.

World maps help us make sense of the world around us, and our place in it.

While mapmakers may portray their world maps as accurate, scientific and neutral, every single one describes the world from a certain worldview and culture. From ancient Babylonia to the Renaissance, cartographers have been driven by politics, religion, emotion and math.

“And that’s because during the 19th century there was a mass immigration movement into Texas from Europe and there are dozens of maps of Texas that were written in German that talked about what a great place Texas is.

A Real National Treasure: Rediscovering the Roanoke Colony

Heather Cox Richardson

Ok, I confess to loving the National Treasure movies. I know, I know, they’re stupid, and they completely twist history, and all that, but they are so much fun! Wouldn’t it be great if there really were hidden passages behind Mount Rushmore? Caches of historical treasures buried under modern cities? Old documents that held secret information, revealing the answers to ancient mysteries?

Oh, wait . . .

Perhaps there are, on that last one.

One of America’s great mysteries has been the fate of the Roanoke Colony, England’s first attempt to establish a permanent settlement in the “New World.” In the mid-1580s, Sir Walter Raleigh outfitted a settlement on Roanoke Island in what is now North Carolina, just inside the Outer Banks (but what was then Virginia, named, of course, for Queen Elizabeth, the Virgin Queen). The first years of the colony under a military governor were disastrous as the governor fought with both local Indians and his own people. The one great success of the venture was its choice of illustrator and mapmaker: John White. His meticulous observations of the coastline and the peoples he encountered are invaluable pictures of the New World as seen by wide-eyed European adventurers.

iPad for Higher Ed Roundup

NEW YORK CITY -- Apple made its much-anticipated move on the education technology industry on Thursday, announcing a revamped version of its iTunes U platform that could challenge traditional learning management
systems. It also unveiled new tools for creating and distributing low-cost digital textbooks that could speed the pace of e-text adoption.>>>

Ask people in educational publishing about Apple’s foray into e-textbooks, and you’ll hear a consistent message: It’s good for all of us—and good luck to Apple.

It’s good for e-textbooks in general because “Every time Apple enters a market, that market gets attention,” as Dan Rosensweig, CEO of textbook-rental firm Chegg, puts it. Widespread availability of e-textbooks on the iPad could help alert a lot of students, teachers, and parents who didn’t know otherwise that such things exist.>>>

Prezi for Historians?

Chris Beneke

Tired of using PowerPoint in your History teaching? You might consider using Prezi instead. Here are some preliminary thoughts. (Maybe you’ve already seen it used here; for a brief overview, check this out.)

Strengths

If you make extensive use of in-class readings and don’t want to distribute the texts in paper form, Prezi can help. It allows you to easily pull the texts up and zoom on important passages. Ditto for high resolution pictures and maps. You could post an entire reproduction of a U.S. or world map and quickly zoom around it. That’s handy.

With Prezi you can easily create a vivid and infinitely extendable timeline, connecting it to relevant images, videos, and text. As far as I know, there’s no way to do this in PowerPoint or Keynote.

Beyond that, the most immediately apparent virtue of Prezi is the fact that it allows for nonlinear presentations. If you’re like me and mix lecture and discussion flexibly throughout the class, that’s an especially attractive feature. Of course, PowerPoint and Keynote allow you do this as well. Just not as gracefully.

Finally, you could, theoretically, save a cluster of class materials or even an entire semester’s worth of materials in the same Prezi. This would save students the trouble of slogging through twenty-plus PowerPoint presentations ahead of their final exam and might also encourage them (and you, history teacher) to make stronger connections between class topics.

Weaknesses

When it comes to usability, Prezi is often coy, seldom allowing you to predict just what it intends to do. The interface will not feel intuitive to PowerPoint users. Right-clicking gets you nowhere. Formatting options are available, but somewhat mysterious. And as far as I can tell, Prezi places new frames wherever it darn well chooses.

Non-linearity has its advantages, but let’s keep in mind that teachers resort to linear arguments for a reason: they make sense to human beings and are easily recalled. One of the virtues of PowerPoint is that it keeps the digression-prone professor on track. Prezi includes a tool (called “Path”) that allows you to fly from one section to another. By zooming out you can see a riveting overview of your class’s trajectory. This has the aesthetically pleasing effect of launching you up, over, and around the various parts of the presentation. I suspect that this novelty will wear off fast and that Prezi will have to rely on other virtues to retain converts. (Another cute feature—the ability to create tiny hidden text—is likely to make it unnecessarily difficult for students reviewing the presentation to find what they need.)

I’m also worried about preserving Prezis over time. With a subscription, you can download them to your computer. You can also save the entire presentation for static use as a .pdf. I don’t find either option reassuring. Prezi’s novelty and its isolation from an existing office sweet offer additional reasons for pause.

This Prezi on jazz bassists illustrates some of the strengths and weaknesses of the software. Though beautiful and moderately instructive, the gratuitous twisting and zooming is dizzying. You can also see that the presentation includes five or so embedded YouTube videos and that one of them isn’t working.

Overall Evaluation

Prezi should appeal to the teacher who needs the technological structure that presentation software provides but also wants to encourage active learning. The ease with which users can vault from timeline, to text, to image, to video—and back again—is certainly alluring. The capacity to zoom into and out of images, including portraits, photographs and maps, should especially charm historians.

In the end, Prezi’s primary contribution to history instruction may be on the teaching side of the teaching-learning enterprise. It should force us to think more rigorously and creatively about the connections residing within our class materials. For that reason alone, it’s worth a try.

* Here’s a tiny text caveat: I tried Prezi for the first time in a local Teaching American History session this past week. The feedback hasn’t come back to me yet, but I got the distinct impression that the results were mixed. In addition to the usual assortment of images and maps that any PowerPoint might include, I pasted in some very long selections from Lincoln’s 1842 Temperance Address. That was a mistake. I ended up reading aloud for extended periods. Looking back, Prezi’s zoom-function may have been the cure to the this disease of my own making. In sum: While you may be tempted to post a large selection from a speech, article, or book chapter, you should resist the urge. But longer excerpted text selections are definitely possible with Prezi.

Digital History Roundup

John Markoff, "It Started Digital Wheels Turning," New York Times, November 7, 2011

Researchers in Britain are about to embark on a 10-year, multimillion-dollar project to build a computer — but their goal is neither dazzling analytical power nor
lightning speed. Indeed, if they succeed, their machine will have only a tiny fraction of the computing power of today’s microprocessors. It will rely not on software and silicon but on metal gears and a primitive version of the quaint old I.B.M. punch card. What it may do, though, is answer a question that has tantalized historians for decades: Did an eccentric mathematician named Charles Babbage conceive of the first programmable computer in the 1830s, a hundred years before the idea was put forth in its modern form by Alan Turing?>>>

Researching a family's military history used to be a real challenge, but as more and more paper archives go digital and are transferred to the internet, it's becoming possible for anyone to leaf out a family tree in surprising detail by using a few tricks and knowing where to look.

Bryan Rosenblithe, "Analyzing history for today: Emerging technologies offer new challenges in the practice of historiography," Columbia Spectator, November 10, 2011

. . . . While it is now widely accepted in the historical profession that current events inform the questions we ask of the past, we are only beginning to come to terms with the profound transformation that digital information is making in every aspect of our lives. A quick comparison of the phrases “digital revolution” with “crisis of capitalism” points to the profundity of both moments and the relatively underdeveloped intellectual apparatus with which we are confronting the issues of our time relative to those of Finley’s day. It is this sense of a radical shift in our way of life coupled with the lack of a vocabulary with which to discuss it that makes the ridiculous statement from Douglas Engelbart, the inventor of the mouse, “The digital revolution is far more significant than the invention of writing or even of printing,” appear meaningful.>>>

Dawn Setzer, "Dr. Livingstone's lost 1871 'massacre' diary recovered; discovery rewrites history," UCLA Newsroom, November 1, 2011

In Africa 140 years ago, David Livingstone, the Victorian explorer, met Henry M. Stanley of the New York Herald and gave him a harrowing account of a massacre he witnessed, in which slave traders slaughtered 400 innocent people. Stanley's press reports prompted the British government to close the East African slave trade, secured Livingstone's place in history and launched Stanley's own career as an imperialist in Africa. Today, an international team of scholars and scientists led by Dr. Adrian Wisnicki of Indiana University of Pennsylvania, publishes the results of an 18-month project to recover Livingstone's original account of the massacre. The story, found in a diary that was illegible until it was restored with advanced digital imaging, offers a unique insight into Livingstone's mind during the greatest crisis of his last expedition, on which he would die in 1873.>>>

Leigh Hornbeck, "Papers show daily colonial life: Old records discovered in Charlton home provide a closer look at a past era," Albany Times Union, October 30, 2011

BALLSTON SPA -- A recent donation to the Saratoga County Historian's Office gives a more intimate look than ever before at life in Colonial Charlton. The LaRue family donated 600 papers found inside a box nailed underneath floorboards of the attic floor in their house. They belonged to Joseph LaRue, an ancestor who moved to Saratoga County just before the American Revolution and served as a justice of the peace for 10 years. The collection includes a docket and written testimony from witnesses and defendants, along with records that show small details of 18th-century life often passed over by traditional historians. . . . Ned Porter, a junior from Skidmore College who worked as Roberts' intern over the summer, sorted the papers into categories and created a finding aid -- a document describing the collection -- with every legible name, which can be used by genealogists and others. The next step is to create a digital record so the fragile papers aren't handled more than necessary. Some of the documents are parchment, but most are thick rag paper. All the writing was done with quill pen.>>>

How Streaming Media Services Affect our Perception of “Owning” Music and Movies

Philip White

Despite the company’s recent price increases, the decision to split its DVD delivery and streaming businesses and the lamentable choice to name the former “Qwikster” (as one friend commented, “It sounds like fast-drying spackling!”), I am an avid Netflix fan. And if the company can increase its still-inadequate library of on-demand content, this miser may eventually ditch my old, 500-pound behemoth of a TV and invest in one with Netflix streaming built in, or maybe just a Roku box. Right now, I occasionally watch a movie on my HTC Flyer tablet, which is a better viewing experience than an iPhone/iPod but still a little rinky dink for my liking.

So why does the ability to get movies without waiting for a DVD to arrive or, heaven forbid, leaving the house to patron the nearest Redbox, appeal? Because it’s quick, convenient, offers a (soon to be) wide choice and there’s a predictable, all-you-can-watch fee instead of an individual charge per disc. And if I sometime think that Amazon’s Instant Video has a better selection, maybe I’ll forsake Netflix.

So that’s the good, but what about the bad or potentially bad? How is the rise of streaming film and TV content affecting studios large and small, and the actors, producers, directors, crew members and others they employ? Were some of the same questions asked when other new technologies were rolled out? The television? The videotape machine?

Certainly, DVD and Blu-Ray sales are down. And movie prices continue to rise, much to my horror. $12 for a ticket? In the middle of Kansas? Really? I also loathe the gimmicky “cinema suites” that offer a crappy buffet and cheap beer if you’re willing to fork over $20 bucks or more per ticket, and possibly the shirt off your back, too. But how much of these price hikes and the luxury concept that seems to be borrowed from major league sports’ premium on suites and boxes is attributable to movie studios, and how much to the theater companies themselves? I admit that I don’t know.

What I do know is that the ability to stream movies and music on demand, on mobile devices as well as at home, is profoundly affecting how we think about owning this content. The point of buying a DVD (I still haven’t succumbed to the allure of Blu-Ray, though after being blown away by watching Saving Private Ryan in this format on my friend’s big screen it has been tempting) used to be that you could watch one of your faves whenever you like. Well, with streaming you can do that, while removing the embuggerance of actually having to get up from the couch, or, in my case, trusty leather recliner.

When I fully embrace streaming, there will be no disc to scratch, misplace or lose to the clutches of the kids. My wife and I will no longer yell at each other for me absent-mindedly putting The Fellowship of the Ring (mine) in the case meant for The Devil Wears Prada (hers). And if a film is bad, there will be no wait while I send the accursed item back to the Netflix warehouse, and then wait for them to send out the next DVD in your queue. Heck, even without switching to video on demand and just using Netflix’s plain ol’ two DVDs at a time plan, I buy less than a quarter of the DVDs I purchased even two years ago. And those I do get or request for a birthday or Christmas present are true favorites, rather than the mediocre films I kinda liked but only watched once a year that I used to purchase or hint at before Netflix. So, for me at least, I’ve almost completely abandoned DVD ownership, without even jumping headlong onto the bandwagon. And I’m not alone. According to Time DVD sales were down by 18.3% in the first six months of 2012, while spending on kiosk and on-demand services was up by 40 to 45%. Movie studios and distributors are doing their best to reverse this trend by ensuring that physical copies are available for rent and purchase a lot sooner than via Redbox, Netflix or Amazon.

The mass adoption of movie streaming is the biggest historical change in the film industry since the

introduction of the VHS-playing VCR to the U.S. in 1977. Once this format had smacked down Sony and its upstart Betamax (what is it with Sony and propriety formats? Anyone remember MiniDisc?), VHS gave people the ability to watch high quality (for that time) productions in their own home, as well as the ability to record live TV. With Netflix and its kind, the focus has shifted again, as it’s now no longer necessary to have a home-based content device, as a tablet or even a smart phone will suffice. We’ve gone from a cinema-based model to home-focused to mobility-focused, which in apt, given the ever-greater ease of international travel and the greater geographical transience within America today.

And what of music? I am not a Pandora user, nor have I logged into Spotify since signing up. I’ve come to prefer Amazon’s MP3 store to iTunes because of lower prices and my love of using the Amazon Cloud Player on my tablet, and usually buy digital instead of CDs, but I still buy as much music as I did a few years ago. Not sure that’s typical though–I know a lot of people, particularly in the UK where Spotify is more established–who listen to music almost exclusively through streaming offerings, whether it be radio or a paid subscription service.

In the U.S., how long will it be before the majority of major labels make 25 percent of revenue through streaming music subscribers to Spotify et al? Is this already diminishing CD and MP3 sales? The concept is similar to the instant video vs. Blu-Ray/DVD debate–a large and soon-to-be unlimited selection at your fingertips against the tangibility and permanent ownership of a physical product. I still find it easier and safer to plonk in a CD while in the car rather than messing around with an iPod, but with voice-controlled media systems becoming more prevalent (the new iPhone, for instance) and the continued success of satellite radio, that may change soon. I was late to the Netflix party, so maybe eventually I will succumb to the charms of music on demand, and stop buying music. I’m determined that vinyl will be the exception–still loving my Technics SL-1700 turntable and the sleeve design and notes on records old and new!

Thoughts? Do you primarily stream music and movies, or still buy individual copies (be they digital or physical)? Are the media changes afoot much greater than those of the 20th century?

Computing Machines

Randall Stephens

How did we get here?

I'm typing this on my MacBook Pro, a laptop that is a gazillion times more powerful and "pro" than the towering, whirring, always-freezing-up computers I used back in grad school. In fact, my iPad is much faster on many applications than the Dell laptop I carted around five years ago. (Check out Dan's great post from February on a related topic.)

For a little wisdom on the early days of computing and the accelerated pace of change, have a look at this clip of a BBC documentary from the early 1990s.

Media and Messages

Dan Allosso

Long before I ever thought of going into the history game, I worked in the computer industry. “Long before” is an interesting issue of periodization. It was about twenty years ago: less than a human generation, but ten or fifteen computer generations of Moore’s Law. In that time, transistor counts on the central processors of computers have risen from a few hundred thousand to a few billion. What does that mean to historians?

I think the biggest change for me as a historian is that content has really become king. The ability to store and move huge volumes of data cheaply and effortlessly has changed the game for people who want to communicate their ideas with others. Network bandwidth and processing power have very visibly led the way, but storage technology has improved just as incredibly. And it’s the ability to store information that makes the whole thing work.

When I started building “clone” computers in the late ‘80s, we were putting 32 Megabyte Seagate hard drives in them. The ST-138R was a physically small drive by the standards of the day, measuring just 3.5” by 1.66” by about 5.25” and weighing a couple of pounds. An OEM could buy them for about $150, making them an attractive entry level drive. We also sold higher capacity drives, but the 32 MB drive and its 65 MB big brother were the “sweet spot,” the best deal on a dollars-per-megabyte basis.

32 Megabytes would hold a lot of text. Average word processor files used a couple dozen kilobytes per page, as they still do today. So you could write to your heart’s content. But there wasn’t a lot of room to store your research. A text-only copy of a decent-sized book (say James Joyce’s Ulysses on Project Gutenberg) took up a Megabyte and a half. So you’d only get about twenty of those on your disk—how you’d get them there was another issue, but we’ll skip over that. And if you were able to get your hands on high resolution images, you’d be lucky to store half a dozen.

Since that time, hard disks have gotten faster, smaller, and cheaper. It’s now possible to spend the same type of money that once bought an ST-138R, and get a disk that’s smaller in size but nearly a million times larger in capacity. Or, if you prefer the ultimate in portability to the ultimate in capacity, you can dispense with disks entirely and store your data on chips. For less than $50, you can carry 32 Gigabytes of data on your keychain.

I recently moved my dissertation project to just such a device. I now carry a 32 GB flash drive that holds all my writing, as well as all my research. In what would have taken a thousand ST-138Rs (that late-80s drive), I can store ten thousand high resolution photos or scans, thousands of books, and all the writing I’ll ever do on this project. Think of a thousand hard drives. Think of the electrical current they drew. They would have filled a room and heated your home. I carry this thing in my pocket (it’s backed up at home and at the office), and it allows me to always have the most recent versions of my work at my fingertips. It plugs into the USB port of whatever computer I happen to be sitting in front of, and transfers my data so fast I can’t tell it’s not on my local drive.

As I’m researching and writing, I can’t help thinking, although I want this work to come out as a regular, old-fashioned, paper-and-cardboard book, my writing and all the supporting primary evidence in its original form fits on a chip. I can’t help but believe that in the long run, this will change the way we do our research, write our histories, and communicate them to other people. The only question in my mind at this point is, will that “long run” be measured in human years, or computer generations?
