Screen, Paper, and Information Overload

Information Overload Nathan Zeldes ponders why words seem to multiply when they move from the printed page to the computer screen.

Screen, Paper, and Information Overload

The following is a guest post by Nathan Zeldes, author of IEEE Spectrum's "How to Beat Information Overload

After I published my Spectrum article on Infoglut, I received many responses through a variety of online channels. That's one of the perks in being an active cyber-citizen: you get to meet interesting people. However, a number of respondents focused on the same complaint: the article, they claimed, was far too lengthy, thereby itself contributing to Information Overload.

This statement puzzled me, because I wrote the article in close cooperation with Spectrum’s capable editors, and in conformance with their expectations. My curiosity piqued, I pulled out some back copies of the magazine from my shelf and counted the pages. Turns out that my article is 3.5 printed pages long, well within the norm for Spectrum feature articles. In fact I recently blogged about the shortening of articles in printed magazines over the decades, using Scientific American as an example; that magazine’s features went down from 12 content pages per article in the sixties to 8 pages in 2009. My 3.5 pager would count as positively brief in Sci Am even today... So what is going on?

What made it even weirder is that looking at the article in the printed magazine, it did not appear particularly long; but even I had to admit that the online version, which, it turns out, is the version the complaining readers saw, does seem to go on and on...

Thinking it over, I realized that there is a key difference between reading online and on paper. The information density on paper is certainly greater: lots more can fit—and be consumed—on a printed page than can be put on a screen of the same physical dimensions. The text of my article fills seven vertical “screenfuls” on my 22-inch monitor; it fits on 2.5 double-page spreads of Spectrum, even though each such spread is a bit smaller than the monitor’s area. This means that I could take in the printed article in three “gulps”, versus seven online. Even more important, the printed version is random access; I can move my eyes across the pages and home in on what I want, taking my cues from the layout, section header typography, and images. The long-scrolling online version is serial access: you need to scroll patiently through uniform-looking text blocks to find anything, and your best strategy would be to read it start to finish serially to see what’s in it. That’s why we use books, and not the scrolls the ancients had: flipping through pages is much more efficient if you plan to skim.

This came as a surprise to me: I'm used to considering online reading as a valid alternative to print (until it comes to snuggling up in bed with a good novel, at any rate). Online has its advantages—searchability being a major one—but in an age of impatience, Gutenberg’s good ol’ system has its benefits as well!

3D-Stacked CMOS Takes Moore’s Law to New Heights

When transistors can’t get any smaller, the only direction is up

Perhaps the most far-reaching technological achievement over the last 50 years has been the steady march toward ever smaller transistors, fitting them more tightly together, and reducing their power consumption. And yet, ever since the two of us started our careers at Intel more than 20 years ago, we’ve been hearing the alarms that the descent into the infinitesimal was about to end. Yet year after year, brilliant new innovations continue to propel the semiconductor industry further.

Along this journey, we engineers had to change the transistor’s architecture as we continued to scale down area and power consumption while boosting performance. The “planar” transistor designs that took us through the last half of the 20th century gave way to 3D fin-shaped devices by the first half of the 2010s. Now, these too have an end date in sight, with a new gate-all-around (GAA) structure rolling into production soon. But we have to look even further ahead because our ability to scale down even this new transistor architecture, which we call RibbonFET, has its limits.
