Walking Home with Sadie
One of the most pleasurable “chores” I’ve ever had is walking our goldendoodle Sadie twice a day. It’s exercise. It’s a chance to see nature’s beauty. It’s a chance to interact with Sadie and informally explore her mind. She likes to vary her route. She likes to return to “known” spots and also to explore new places. She knows when we are “headed home.” And, once we begin heading home, she typically begins to engage in a variety of “procrastination” behaviors. She stops and licks herself. She stops and looks back to see whether any of her neighborhood friends—human and dog—are headed our way. She suddenly finds an incredibly interesting scent to track down.
Her procrastination is something I completely understand. I did the same thing as a kid. And my kids did the same thing. And their kids did the same thing. While I sympathize, it also gives me a chance to think. What does it mean to be heading home? Can one ever go back home?
Undo and Home Base
Early in my career as a researcher in Human-Computer Interaction, I had an opportunity to contribute to a set of “Guidelines.” Although the New York Times once erroneously ascribed the “invention” of UNDO to me, I did not invent it. It seems to me that the concept is actually quite old. I did, however, mention in the guidelines that UNDO should be provided as well as providing a “Home Base”—that is, a way to go to a state where you could begin again.
To Sadie, and to me, our home is our home base. Like other home bases, we conceptualize them as being a return to an unchanging safe space. Relatively speaking, and roughly speaking, that’s a good characterization. It’s relative because no place on earth is absolutely safe. Disasters can come in many forms: extreme weather, wars, crime, and disease to name four. Also, even if disaster doesn’t strike, we can be sure that home will never be exactly the same as when we left it. Everything is constantly in motion and in flux. It can be comforting to imagine that home stays the same, but it doesn’t. Nor does Sadie. Nor do I.
Another Sunrise
Sometimes, a moderate amount of change is nice. I like to take photos in our beautiful garden. I end up sometimes taking pictures of “the same” plant or flower several days in a row. I also tend to take flowers when they bloom, year after year. Sometimes, these pictures look very similar on successive days or on successive years. But in actuality, they are never exactly the same. The plant itself changes day to day (as do I; as does Sadie; as do you). In addition, the light changes from day to day. The surrounding plants in the garden also change from day to day and year to year. In addition, when I take a picture, I’m not in the exact same position. The software on the iPhone changes over time as well. The lenses on the iPhone change over time. Even if by some industrial strength replicability dream (nightmare?) I could take exactly the same photo, you wouldn’t perceive it as the same because your eye/brain system is always changing, both organically and by virtue of your other visual experiences.
Another Sunset
There are characteristics of sunsets that we see as similar over time. Here are three sunset shots years apart.
Another “Another”
Are there any replications? In my mind, sure. In reality, no.
A rose is a rose is a rose, but not only are two different roses ever identical. Even one rose is not the same day after day, hour after hour, or even second by second.
Another Trip Around the Sun
What is more steady than the movement of the earth around the sun…or the sun around the earth.
In the Medieval times, the Europeans wanted to describe in perfect circles and put themselves at the center of the universe.
Now, we are more sophisticated and know that the earth actually orbits the sun. Our seasons depend on the relative position of the earth and the sun. But while we are aware of our trip around the sun, earth does not return to the same spot. Today is November 1. Next November first? The sun will have traveled through our galaxy 6,942,672,000 kilometers. That’s a far piece. I’ve run a number of 10K races. The galaxy travels a lot faster.
Another Homecoming?
Is it possible?
Can we use time machines?
Can we go back to the 1950s?
Can women simply forget that they were once treated as human beings?
In order to work effectively, today’s technology presumes a whole set of other technologies, skills, infrastructure, attitudes, processes, laws, rules, regulations. If we actually tried to go back to 1950, we would miss.
By about 500,000 years. Every so-called primitive tribe ever studied has customs, rules, practices, and rituals. Going back to the 1950’s by destroying the rule of law won’t work no matter how loudly people scream for it. You can’t scream your way to the moon. You can’t scream your way to Mars. You can’t scream your way to happiness. You cannot make two plus two equal five, no matter how loud you scream. Sadie can’t bark them into equivalence. A snake cannot hiss them into equivalence.
You can typically get yourself home. But no matter how hard you “insist,” home will not be in precisely what it was when you left. And, it definitely won’t be in the same place in the universe. Not even close. Going back is a mental exercise and never a physical reality.
