As of this writing, you can walk the streets of New York City, San Francisco, Palo Alto, Las Vegas, Denver and Miami–maybe more. The automated stitching of panoramas from different days and times makes for some high-tech surrealist photography. Continuing the twisted translation of reality into the Googleverse…. Just wait until these are fed by realtime surveillance/web cameras and the most-recent geotagged Flickr photos.

Edward Tufte at Stanford

Edward Tufte spoke at Stanford this afternoon and I had the pleasure of being in attendance. It was an unconventional talk, as far as academic lectures go, for Tufte was speaking “in the first person” about his own life: his origins in rural Nebraska, his education and formative years, his mentors who influenced his thinking, and the turning points that signaled moments of profound reorientation. As Tufte noted, for a sample size of N=1, the estimated variance is infinite; so other sources should be consulted.

Tufte has had a remarkable career and speaks as someone who appears to have found the courage to follow his bliss, leaving a tenured professorship at Yale to self-publish his famous books on visual information, go on speaking tours, and make large-scale landscape art in his Connecticut backyard.

There were three big lessons I took away from his talk.

Contribute to forever knowledge.

The most important decision a researcher makes is choosing what problem to focus on. One should choose problems that are not only profoundly important, but ones for which good progress is possible. It’s worth nothing to work on grand problems and make no progress. Tufte’s own compass for this decision: contribute to Forever Knowledge. That is, create knowledge that will be universally useful to humankind in any time or place in human history. Tufte ditched his career as a political economy theorist because he found he was working on only temporarily important problems, things he decided were not worth his “time, energy, passion and mind.”

Be self-exemplifying.

In whatever one’s work, be not only a great communicator of ideas and practices, be an exemplar of those same practices and this will communicate the value of what you are saying far better than anything else. Tufte’s books are not only superb treatises on the visual display of information, they are also exemplary demonstrations of clear visual communication. I call them the Kama Sutra of information graphics.

Strive for personal utopia.

Here again, Tufte is, as he presents it, self-exemplifying. While utopian cultures may be unattainable, you can pretty well approximate an ideal life through clarity of purpose, courage to act on that purpose, and, most importantly, doing what you love.

The poem Tufte opened his talk with was excerpted from T. S. Eliot’s Four Quartets, fitting for a self-reflection.

Time present and time past
Are both perhaps present in time future
And time future contained in time past.
If all time is eternally present
All time is unredeemable.
What might have been is an abstraction
Remaining a perpetual possibility
Only in a world of speculation.
What might have been and what has been
Point to one end, which is always present.
Footfalls echo in the memory
Down the passage which we did not take
Towards the door we never opened
Into the rose-garden. My words echo
Thus, in your mind.
But to what purpose
Disturbing the dust on a bowl of rose-leaves
I do not know.
Other echoes
Inhabit the garden. Shall we follow?

This is a 1728 Geometry text.

Geometry was the network science of its day, with its richly visual mathematical aesthetic. This is the sort of beautiful abstraction that would drive someone to spend years of life teasing out the endless permutations of a set of axioms. 1728 was the height of the Age of Enlightenment, long before Godel came and tread on the dreams of the humble mathematical ascetic.

Today, researchers of all stripes learn an unspoken rule: beautiful visualization of data makes for “sexy” science. In other words, cool information graphics lead to tenure. It’s partly because visual communication is simply more compelling and has a wider mass appeal. That’s why networks research shows up in the New York times: because it has sexy graphics, not because it’s going to catch terrorists.

It’s no wonder that someone like Edward Tufte, an authority on the visual display of quantitative information, is a kind of cult hero. His books are the Kama Sutra of information graphics.

The tag cloud displayed on my name tag at Stanford University’s H-STAR faculty retreat.

I created tag clouds for every professor’s name tag to visualize their research interests based on research statements and resumes. It was such a treat to watch these great minds interacting and using the tag clouds as launching points for conversations.

I made the tag clouds at TagCrowd. Check it out and play with creating your own clouds from your papers, resume, poetry, chat logs, or whatever suits your fancy.
