I’m thrilled that my SXSW Interactive 2011 talk is finally up on YouTube! Now you can listen to my talk in the comfort of your home.




Thanks to Keegan Atkin for an awesome editing job!

We plan to get it up on Slideshare soon, too.


James W. Clardy at Dell told me about this lunchtime clock. It speeds up 20% every day at 11:00 and slows down 20% every day at 11:48, giving you an extra twelve minutes of lunch to enjoy. Twelve minutes may not seem like a lot but, to put it into perspective, this is a full additional hour of lunchtime gained every week.  You can build it yourself, too, using the instructions available at http://www.instructables.com/id/Lunchtime-Clock and the Adafruit DS1307 Real Time Clock Kit.

Albert Einstein told us that there is no universal clock somewhere that keeps absolute time.  “Time and space are modes by which we think and not conditions in which we live, ” he said. So why not bend time a little, here and there, if we feel like it?   Time is our sandbox.

Guest post by Lauren Patten, New York City

At 7:15 on the morning of August 7th, 1974, Philippe Petit stepped off of the South Tower of the World Trade Center and began his forty-five minute celebration of transcendence. After years of deceptive trickery and secret planning, Petit and his team, armed only with an enormous steel cable and various riggings, snuck onto the rooftop of the South Tower in the dead of night to prepare for the dawn’s performance. They shot the cable over the massive void with a bow and arrow, bridging the gap between the Twin Towers and between physical reality and the vision in Petit’s mind. Once the cable had been secured and all dangers of friction between the cable and the towers minimized, the celebration began.

With only a 55 pound balancing pole to aid him, Petit made eight journeys across the space he created, a world of his own 110 stories in midair. A quarter of a mile below him, the morning masses of Lower Manhattan had stopped in their tracks. Petit could hear their cheers as he danced in the face of death, saluting the towers that he stood even with. The entire city of New York celebrated with him as the limits of human power fell burning to the ground. It seemed as if this dance would last forever, a public performance framed only by the rooftops and the sky.

But Petit had to come down from the wire at some point, and the limits he had shed were waiting for him on the ground. Petit was arrested on several charges, even performing without a permit, but these were later dropped; it seemed ludicrous to put handcuffs on a man who had broken free of the Twin Tower’s steel shackles. Instead of time in jail, Petit was given a lifetime pass to the World Trade Center’s observation deck. In the documentary Man on Wire, Petit is shown signing his name on the steel of the rooftop, permanently etching his triumph over the tower into the framework. Petit was not satisfied with merely transcending the limits of physical space. Now he had transcended the limits of human permanence, declaring his existence not just in the memories of Manhattanites, but in indelible ink on the surface of the South Tower’s roof.

Most monuments in New York, such as the Twin Towers, are built for permanence, as if they intend to disprove the limits of time. The Statue of Liberty forever gazes out on the horizon, welcoming journeymen to the melting pot of America; Grand Central Terminal still boasts the constellations on its ceiling, as if they could guide the passing travelers to a mystic destination via train. This dormant quality is found in many neighborhoods of New York as well – Park Avenue is one of these spaces. Along the Avenue in Midtown, ornately carved apartments from the early 20th century blend into an endless monolithic row. Pedestrians stride by at a productive rate, systematically disappearing one by one under the outstretched awning of a stony apartment building or through a corporation’s translucent glass doors. The wide street, bordered by the parallel buildings, is populated mostly with yellow cabs and sleek black town cars, separated only by the Park Avenue Malls.

For us, it does not matter so much the way the mightiest towers in our lives eventually disintegrate into rubble before our eyes. We are in motion within our panoramic circles, each step taking us closer to the new physical reality that will be built from the roots of that rubble. The high-wire dances we perform are not for the dance itself, but for the moment we step off of that wire and crane our necks up to the sky to see what it’s become.

Here’s the text of my talk at SXSW Interaction 2011, March 12, 2011

It’s about time: visualizing temporality

Slide 1   Hi

My name is Joanna Wiebe; I’m an interaction designer and I work in e-commerce. My husband took this of me in Jamaica a couple of years ago. My web site is onemind.com, and my twitter hashtag for this event is #temporality.


Slide 2   It’s about time

Interaction designers can have an interesting and shamanic role in our global village, and that’s what I’m going to talk about.


Slide 3   What is time?

My immigrant Ukrainian grandfather arrived in Montreal without a watch. He walks up to a man on the street and asks, “Please, sir, what is time?” The man replies, “I’m sorry, you’ll have to ask a philosopher. I’m just a physicist.”

My favorite philosopher, Alfred North Whitehead said “It is impossible to meditate on time and the creative passage of nature without an overwhelming emotion at the limitations of human intelligence.”  IT does boggle the mind. As a matter of fact, if you’ve read Zen and the Art of Motorcycle Maintenance, you’ll understand what I mean when I say I have had a few Phaedrus moments as I prepared this talk.

However, let’s give it a whirl.  Let’s be armchair philosophers.


Slide 4   What is time?

Kids have no idea about time, nor do they care.  I taught my children about clocks, and calendars, and timeliness, and it wasn’t easy.

Now that they are grown, they are time slaves, like me. But sometimes, doesn’t time seem to disappear? When you are very emotional, meditating or praying, listening to music or feeling the earth move?

A French geologist named Michael Siffre went underground for several months to live in a cave without clocks or calendars. He wanted to live “like an animal”, he said.   His days gradually stretched out, starting with twenty-four and a half hours, then more and more until eventually he was sometimes living 48 hours days.  He always thought the days were twenty-four hours, and even though he kept a diary to record his activities during a “day”, he couldn’t tell the difference between these long 48-hour days and a “normal” day.

In a recent interview he said, “It’s the problem of psychological time. It’s the problem of humans. What is time? We don’t know.”


Slide 5    A one-minute history of time

Humans have had many ideas about time over the centuries. In the Medieval world, time – and space — were just a static backdrop for the earth, the center of everything. This geocentric concept is shown in this astronomical clock, built in 1410 in Prague. The blue circle in the middle is the earth.

Copernicus, in the 16th century, taught us that the earth and planets revolve around the sun.

In the Renaissance, Galileo studied the phases of the moon, and developed the pendulum clock.  In the 1700s, Newton described a mathematical, clockwork universe. People imagined God as the Big Watchmaker.


Slide 6   The arrow of time pointing to the end of time

Our next big idea was that the sun is part of a galaxy, among billions in the universe.   The second law of thermodynamics gave us the concepts of entropy, an arrow of time leading to our universe’s eventual cosmic heat death, and an end to time.


Slide 7   The arrow of time and the evolution of time

Charles Darwin drew a picture of biological progress. The arrow of time is pointing forward, he said, and everything’s evolving!  Philosophers, people of faith, and other scientists jumped on his bandwagon. Some people, like Tielhard de Chardin, said that even space-time will evolve into something else.

Slide 8   Mental models evolve

We care about time because we’re going to die. We keep track of time by the rhythms of tides, seasons, sunrise and sunset, heartbeats and menstrual cycles.   These are all local clocks, relative to the observer. In fact, that’s all there is, according to Albert Einstein. There is no universal clock somewhere that keeps absolute time. He said, there’s nothing really, that anyone can point to and say, that’s the past, here is the present, there is the future.  Past, present and future are just ideas.  “Time and space are modes by which we think and not conditions in which we live, ” he said.

And our mental models of time also keep changing. This is not a picture of Einstein, but of Richard Feynman, a theoretical physicist who was an excellent drummer, and whose mental models of time are so evolved that I don’t really understand them.


Slide 9   Four-dimensional design

Some days, it seems like a big part of my work is thinking of ways to let people know that they are just going to have to spend some of their precious time on earth waiting.

As my friend Anne Kennedy says, the web is the only four-dimensional media. And as I say, time is the crux of interaction design.

Slide 10   Digital interaction happens in time

Every digital interaction is a series of actions over time, between two or more agents, human or nonhuman. A person’s keystroke takes a fraction of a second but a system response can take milliseconds, or on the other hand, several days. Uploading my entire hard drive to dropbox.com took four days.   To research this talk, I completed a 15-year interaction by retrieving an article I wrote and published to my web site in 1994, by going to the Wayback machine at internetarchive.org.


Slide 11   Time-boxed interactions

Some interactions are time-boxed. My bank holds me in a live session for only a specified time before I have to login again. My search results at Kayak are only valid for a certain amount of time.   Ticketmaster makes me race against the timer to enter my credit card information and get the seats I want.


Slide 12   Temporal interaction challenges

As interaction designers, we have some time-related challenges.  Designing for different cultures, which hold diverse views of time. Designing interactions that span time zones. And inventing the path beyond technology.  I’ll also talk about some cognitive tools that I hope will help you.


Slide 13   Playing nicely even though we see time differently

If we are designing for global audiences, it helps to know how people of different cultures visualize time.


Slide 14   Time flies like an arrow

Groucho Marx once said, Time flies like an arrow but fruit flies like a banana. I agree about the banana, but I am not sure about the arrow.

What is the shape of time? In our culture, time is an arrow. If you want to give someone the idea that you are goal-directed, that you are fast, that you get things done, then you include an arrow pointing forward – to the right — in your logo.    Of course, the arrow may be pointing us toward cosmic heat death, but whatever.


Slide 15   Cycles, spirals and fractals

Some cultures see time like a wheel, with cycles of recurring events.  Or it’s a spiral, and you can move up or down the spiral with each rebirth.  Maybe –even — all of space-time is an evolving fractal, a simple algorithm that yields infinitely complex patterns!


Slide 16   Customer travel lifecycle

As interaction designers, sometimes it is useful to think of processes as cycles. This is a diagram of the cycle of tasks relating to personal travel, and the databases that track and store each person’s choices at each step in the cycle.

Slide 17   Time orientation

Some cultures have a long-term orientation, which is an outcome of being focused on the future, persevering, and being patient in waiting for the results, saving for the children, ten-year business plans.  China is an example of a culture with long-term orientation. The United States is seventeenth in long-term orientation, last time I checked.

Last year, I redesigned the car rental flow for ebookers.com.  The existing date picker for ebookers was designed by an American, and displayed one month at a time, with arrows to display future months. Because people rent cars a week or two ahead of time, right?  But when I spoke with our UK product manager, I learned that our European customers rent cars, on average, about 56 days in advance.


Slide 18   Sixt calendar

In fact, some of our competition in Europe already had three-month calendars.


Slide 19   Sequential and synchronic cultures

Another dialectic in the way different cultures view time is whether they structure it sequentially, or synchronously. These terms are from Fons Trompenaars, a Dutch consultant in cross-cultural communication.

In a sequential culture, time is definitely an arrow. Time moves relentlessly forward, second by second, minute by minute, hour by hour, day by day, in a straight line, from the past to the future.  Our day is sectioned, so we can do things one after another.  Time is a commodity. Time is money. So a web site for our culture has to be navigationally efficient.

Then there are more synchronic cultures, which I am reminded of when I look at the snapshot on the right from my holiday in Jamaica.  A relationship is valued more than staying on schedule. A date made for a specific time is more like a wish, or a temporary desired outcome based on the now. Designing for a culture with a flexible model of time, we might include browse, search or explore features rather than just linear navigation.


Slide 20   Living without time

It’s fun for me to think about designing software for cultures that think about time completely

differently.  The traditional Hopi and the Mayan cultures, for example, don’t really have any words for “time”.   The Hopi language just puts everything into two buckets – the manifest and the unmanifest.  The Mayan cultures have two interlocking calendars, one with 13 months of 20 days  and the other more of a solar calendar.


Slide 21   Days as gods

Mayan word for “day”, kin, is the closest thing they have – but this isn’t any abstract unit of measure.  Each day has a unique personality, and is creative. In other words, the days are gods.

Another interesting aspect of Mayan time is that time stacks up. Time is cumulative.


Slide 22   Zero point

I cannot omit a mention of Terence McKenna’s view of time, in which time and space are the interplay of habit and novelty.  At the “zero point”, or singularity, on December 21,  novelty will achieve infinity and something will happen – I’m not sure what.

Also, if you’re interested in these things, Google “Schuman Resonance” for a rationale of how by the end of 2012, time will have sped up so much that  “time will stop”, or potentially, be transformed.


Slide 23 Interactions among people who see time differently

If you are designing for a specific culture, you can ask:  What is the shape of time for this culture? Is it an arrow? Cyclical?  Does the culture have a long- or short-term orientation?  Is it sequential or synchronic?  Does this culture have a unique view of temporality?

If we are designing for a global audience, should we just use our own Western approach and force everyone to this standard? Or is there a way we can make the software work for people of many cultures?


Slide 24  An operational model of time that works across time zones

Think about what kind of an inner picture of time you can have, when you can get in a plane and travel anywhere in the world in 36 hours, your body adjusting to any number of the earth’s 24 time zones, not to mention daylight savings time, which starts early tomorrow morning, by the way?


Slide 25   Body time

Here I am, completely jetlagged, at the end of an 18-hour day of traveling.  When my husband took this shot of me, I was no longer in any earthly time zone. I was in Body Time, the aggregate response of my own biology to the shifting temporal landscape of travel.  Haven’t you had that experience of arriving at “breakfast time” when your body is pleading for “bedtime”?  I want someone here today to make the tools, that would help people make sense of this kind of experience, to integrate the personal, bodily-felt experience of time with clock time?  TripIt doesn’t do it for me.


Slide 26   Now zone

We’re here at SXSW, in this room, but I bet at least some of you are also connecting with family and friends in other places. With texts, Google calendar, Skype, and emails, we are living in a new kind of time zone: the Now zone. When we talk with one another, we are together at the same time, NOW — no matter that the clocks say that the times are different.  But when we make plans with someone in another time zone, we always have to make it clear, is that your time or my time?  Like the poet Rilke said, “the clocks move separately from our authentic time.”


Slide 27   Achieving an operational model of time that works across time zones

I read a tweet the other day, from a woman who was complaining that she suffered from “multiple temporality disorder” from living in two time zones six hours apart.

Time systems were set up to be local, and we don’t live local any more. We live global. We need to design systems to help us make sense of these experiences of time in our global village.  Not just engines that translate one time zone to another, although that helps.   I’m envisioning a new kind of calendar.  A new language of time. Clocks that operate on our breath, our heartbeats?  On the internal resonance of the earth?  Got some better ideas?


Slide 28   Finding the path beyond technology

In my lifetime, I’ve gone from using a phone that was a wooden box on the wall, to this little powerhouse device called an EVO.


Slide 29   Finding the path beyond technology

I’ve gone from using a sequential TV schedule in the newspaper, to Amazon Instant video, where I can watch what I want, whenever I want.  Our devices are miniaturizing. It’s up to you to make them cognitively invisible.  Just the way you enter a room today, and the light automatically comes on, and you don’t even think about it, people will use your technology without being conscious of it.  It will be a natural extension of themselves, just part of the ecosystem.


Slide 30   Real-time

Maybe when you think of real-time transactions you think of Google’s Instant Search or texting.  Here’s a different kind of real-time I just read about a few days ago. In the past, farmers in the market for newborn piglets would have to drive to town to check the farmer’s coop bulletin board.  Now, for newborn piglets, just search Craigslist.


Slide 31   Feedback loops

As real-time interactions become the norm for almost everything, we will be able to keep track of the health of people, populations, economies, and environments, and do something about problems more quickly.  Like Katrina or the earthquake and tsunami in Japan. Real-time will give us the feedback loops physicist Friz Capra talks about, to regulate ourselves as a planet.

Physicist Fritjof Capra has said, “. . .a community that maintains an active network of communication will learn from its mistakes, because the consequences of a mistake will spread through the network and return to the source along feedback loops. Thus the community can correct its mistakes, regulate itself, and organize itself . . . The pattern of life, we might say, is a network pattern capable of self-organization.”

With everything you learn that makes you a better interaction designer, you are working toward building an active network of communication around the world.  You are moving our systems toward the day when we can fluidly talk with one another in real-time. Of course, it will still be up to each one of us to decide to have goodwill and practice it with one another. But you can give us the possibility of economic and political systems in which everyone can participate in open, global interdependency. You’re moving the needle toward Marshall McLuhan’s “brand-new world of allatonceness” in which time has ceased and space has vanished, where we will be, as McLuhan has said, profoundly involved with one another.


Slide 32   Latency, session management and timeouts

But, we’re not quite there yet. Last night, I sent my husband a text message, and he responded. My phone indicated that he had texted back, in fact, two minutes before I had sent him the original message. Now, that’s latency!

To get to true real time, much has to be done on the front end AND our back end systems.  And as designers, we need to understand our existing back end systems so we can make the best use of them.

Here’s my husband Tim, eating chips on the balcony of a hotel in Spain. The picture reminds me of the frustrating afternoon I spent trying to book that hotel, getting timed out over and over again.

The exciting part was that I worked at Orbitz, so I had a chance to help fix the timeout problem.

Why? I asked.  Why these short sessions?  Why can’t we just hold everyone in session indefinitely?

I learned that each hotel search called on a byzantine collection of global distribution systems for hotel inventory.  Orbitz servers stored this collection of search results to create a stateful session from the essentially stateless behavior of the web. Our power wasn’t metered, so it wasn’t a matter of electric cost.  But increasing session lengths or having more sessions had an impact on server performance. There were load issues at peak times of the day.

Also, it’s not safe to prolong everyone’s sessions indefinitely if credit card information has been entered.  Travel data and prices quickly become stale, and there are latency issues with continually refreshing the data.

First of all, we increased session time across the board as much as we could without affecting performance or latency.  Then we also timed out different pages in the booking path based on historical behavior of our key market segments. If the customer clicked on a select group of triggers, they would be asked if they would like to see refreshed results. We still had the same old awkward backend systems but we had improved the user experience through interaction design.  Bookings went up.


Slide 33   Tools for time work

To do brilliant work with temporal issues in the user interface, here is a short checklist of cognitive tools you might find useful.  By the way, it helps me to think of interaction design like composing music, because a lot of the same fundamentals apply.

-        Sequence

-        Pacing and rhythm

-        Duration

-        Interval

-        Patterns

-        Priority


Slide 34   Sequence, and direction

To be an interaction designer, we have to be masters of sequence, and the direction of sequence, the subtleties of cause and effect. This is the cover of the graphic adventure video game Myst, in which the player explores an environment to see which causes will trigger helpful effects.  As designers, how do we know when to make an effect explicit, and as discoverable as possible?  How do we know when should we make the effect a learnable surprise, like in Myst?


Slide 35   Process flows show sequence

This is an example of a process flow I designed for a single screen of a back-end tool, to try to tease out all the conditional steps in a process, and which causes would lead to which effects. You don’t need to read all this – I am just showing you this to illustrate just how complex these box and arrow decision trees can get.


Slide 36   Functional descriptions that show cause and effect

And here’s a more traditional information architecture wireframe, again annotated with functional specifications so the developer knows what each trigger is supposed to do. Again, don’t try to read this.


Slide 37   Conceptual Graph Structures

Another tool for working with sequence is a cognitive task analysis method called Conceptual Graphing.  In this method six kinds of nodes are connected by a formal grammar via 18 types of arcs, setting up semantic relationships. This method is based on research into how people tell stories.   Here’s a hand-drawn example from my friend Scott, who introduced me to this method.  For a deeper dive on this, check my web site. http://onemind.com/2010/01/27/conceptual-graph-structures-part-1/


Slide 38   Pacing and rhythm

Are you designing a roller coaster or a tea party?  What’s the most efficient rhythm of work for the typical person?  What pace is going to be the most fun? Every journey has its natural pace, including the paths through an e-commerce form, a game, or a web site.  Push it too hard or go too slow, and it’s just painful. Or even impossible. Then also consider, are the people novices or experts? Are they multi-tasking or will they be giving this effort a single-minded focus?

The mind can absorb no more than the seat of the pants can endure. Is a group of tasks something that a person can do in a single sitting? Or are you going to make them get up several times to go find information that they don’t readily have at hand, interrupting their pace?  Are you going to make someone click “Next” and “Next” and “Next” without giving them clues as to how long this is going to take?  Are you going to interrupt them with interstitials and progress bars?
Slide 39 Duration

A time-related user interface problem, which I don’t think anyone has solved, is how to visually display an array of flights with their relative durations, as well as the durations of stopovers, overall elapsed time, time between flights, actual time in the air for each portion of the flight, time zone shifts, probability of delay, not to mention depart and landing times.  This is a screen grab of an experiment in how to display flight duration.

Slide 40   Interval

When I began working at Orbitz, one of the first time-related issues I ran across was that there was not a common understanding of the intervals in a person’s itinerary. So I put together this diagram of flight components so we could start to think about these intervals.


Slide 41   Patterns

Time gives us context for understanding data.  In time series visualizations, we can see how things change over time.  Are there trends, patterns? What is the rate of change?

There are many time series display methods: from line graphs to heat maps. Stephen Few, Ben Shneiderman, Edward Tufte, and many others have done excellent work in the field of time series display.


Slide 42 Lifelines

Here’s an example of some conceptual work Shneiderman was involved in at the University of Maryland, to use interactive time series display for personal medical records. A single screen displays an expodable timeline of a person’s entire medical history.


Slide 43 Priority – implicit or explicit

Within the sequence, what should people do first?  TurboTax gives you an implicit priority by the sequencing of the icons, and the 3-D, time-as-an-arrow diagram. An explicit priority of tasks can be shown through numbering. A wizard interface imposes priority.


Slide 44   The interaction designer as shaman

Speaking of wizards, this is Tim, the Shaman, from Monty Python and the Holy Grail. Tim says to the brave knights, “Follow. But. Follow only if ye be men and women of valour.“

I like Esther Dyson’s comment, “I’ve always done things I wasn’t ready for.”  Whether or not you feel you have the skills, or the experience, or the background, be brave. Help people connect across cultural differences. Across time zones.  Make technology that’s easy as breathing.  Invent new calendars and clocks.  This kind of work will help people do what they want what’s most important to them.  Which is to love and be loved by others.  To be in relationship.  To have some fun. We want to work, play, support our families. And we want to do it in a way that we aren’t piling up five pounds of trash per person per day the way we are now.  So that the polar bears can live, and the baby birds aren’t full of plastic bits, and the air is clean.

My vision is of a computing world where we are help be these kind of people – and ever more so – in a way that we’re not thinking to ourselves, “now I’m using a computer,” or, “now I’m running software applications now,” or, “now I’m using a wireless network device.”  My vision is that everything’s going to be effortlessly integrated, so that we’re just doing the things humans like to do – work, play, learn — eat, pray, love – and the tools we are using to get things done just fade into the background of our awareness.

Slide 45   The power of a vision

A rock pile ceases to be a rock pile the moment a single man contemplates it, bearing within him the image of a cathedral.

- Antoine de Saint-Exupery

Looking back over history, we can see that new designs for clocks and calendars have often been the precursor of some kind of revolution or another.

Time is our sandbox. We can expand time.  We can make time fly. We can bring people together in the Now zone, to heal and to help.

This kind of work we can do seems shamanic, to some, because we see a pattern where others only see a pile of rocks.

I love these notes Jess Hanesbury took on my talk this morning at SXSW Interactive 2011.

#temporality on Twitter to see other comments.

Thanks to all of you for coming to hear me talk. Keep up the conversation!


And an astronomer said, Master, what of Time?

And he answered:

You would measure time the measureless and the immeasurable.

You would adjust your conduct and even direct the course of your spirit according to hours and seasons.

Of time you would make a stream upon whose bank you would sit and watch its flowing.

Yet the timeless in you is aware of life’s timelessness,

and knows that yesterday is but today’s memory and tomorrow is today’s dream.

and that that which sings and contemplates in you is still dwelling within the bounds of that first moment which scattered the stars into space.

Who among you does not feel that his power to love is boundless?

and yet who does not feel that very love, though boundless, encompassed within the centre of his being, and moving not from love though to love thought, nor from love deeds to other love deeds?

and is not time even as love is, undivided and spaceless?

But if in your thought you must measure time into seasons, let each season encircle all the other seasons,

and let today embrace the past with remembrance and the future with longing.


Kahlil Gibran: The Prophet. Alfred A Knopf, New York, 1976

This is reading list is for my talk this weekend at SXSW Interactive,  It’s About Time: Visualizing Temporality, at 9:30 am Saturday, March 12.

About Time: Einstein’s Unfinished Revolution—Paul Davies, Simon & Schuster, 1996

You may have read Stephen Hawking’s A Brief History of Time and are hungry for more.  Davies’s compassionate and intelligent prose provides someone like me with absolutely no background in physics enough meat to chew on.

Language, Thought, and Reality—Benjamin Lee Whorf, The M.I.T. Press, 1956

Benjamin Lee Whorf became one of the most influential linguists of his time, while still working as a fire inspector for the Hartford Fire Insurance Company.

“…the forms of a person’s thoughts are controlled by inexorable laws of pattern of which he is unconscious. These patterns are the unperceived intricate systematizations of his own language……”And every language is a vast pattern-system, different from others, in which are culturally ordained the forms and categories by which the personality not only communicates, but also analyzes nature, notices or neglects types of relationship and phenomena, channels his reasoning, and builds the house of his consciousness.”

“What surprises most is to find that various grand generalizations of the Western world, such as time, velocity and matter, are not essential to the construction of a consistent picture of the universe. The psychic experiences that we class under these headings are, of course, not destroyed; rather, categories derived from other kinds of experiences take over the rulership of the cosmology and seem to function just as well. Hopi may be called a timeless language.  It recognizes psychological time, which is much like Bergson’s “duration,” but this “time” is quite unlike the mathematical time, T, used by our physicists. Among the peculiar properties of Hopi time are that it varies with each observer, does not permit of simultaneity, and has zero dimensions; i.e., it cannot be given a number greater than one. The Hopi do not say, “I stayed five days,” but “I left on the fifth day.” A word referring to this kind of time, like the word day, can have no plural.”

The Loom of Language: An Approach to the Mastery of Many Languages —Frederick Bodmer, W. W. Norton & Company, Inc., 1944

“One of the merits of our own language is that we leave much to the context. Whether the English conjunction when refers to an event which has happened once for all, to an event which happens repeatedly, or something which is still going on is immaterial if the setup makes the distinction clear. We do not customarily use whenever unless we wish to emphasize the repetition of a process, and we are not forced to use while unless we wish to emphasize simultaneity. This is not true of German or of Norwegian. If he is talking about something that is over and done with a German uses als where we should use when. A Norwegian uses da.” (he goes on to give more examples)

The Voices of Time: A Cooperative Survey of Man’s Views of Time as Expressed by the Sciences and by the Humanities—J.T. Fraser, Ed., George Braziller, 1966

This is the most comprehensive look at time I’ve encountered. Time in philosophy, religion, language, literature, music, psychology, psychiatry, and a panoply of the sciences. Some of the sections I particularly enjoyed were: Joseph Needham on Time and Knowledge in China and the West, Jean Piaget on Time Perception in Children, M.-L. von Franz on Time and Synchronicity in Analytic Psychology, Milic Capek on “Time in Relativity Theory: Arguments for a Philosophy of Becoming” and of course Fraser’s lovely commentaries  here and there like icing on the cake.  Fraser was a founding member of the  International Society for the Study of Time.

I will be adding to this list of books that touch on time, from time to time.


A child, playing with the same toy over and over again, lives in a single seamless moment from dawn to dusk.

She is living outside time, or maybe deeply within it.

Swiss psychologist Jean Piaget’s studies of children showed that it is between the ages of six and twelve that kids learn how to order events in sequence, classify durations, and measure time in general. Piaget comments “The child inevitably imagines that when he begins to run, the clock goes more slowly than he does, or that when he walks, the clock goes faster.”


Our basic clocks are experiences like the rhythms of tides, seasons, sunrise and sunset, heartbeats and menstrual cycles.

In the Medieval world, space and time were just “there”, an unchanging backdrop to nature. Earth was the center of the universe.

Copernicus, in the 16th century, learned that the earth and planets revolve around the sun.

In the Renaissance, Galileo studied the phases of the moon, and developed the pendulum clock.

In the 1700s, Newton’s mathematics pointed to a mechanistic, clockwork universe, with a Big Watchmaker, God.

We learned that the sun is part of a galaxy, among billions in the universe.

The second law of thermodynamics gave us the concepts of entropy, an arrow of time leading to our universe’s eventual cosmic heat death, and an end to time.
