Exponential Growth

In his new lecture for the Long Now Foundation, Geoffrey West asserts that part of the problem humans face is that we tend not to understand exponential growth. An economy growing at a miserable 2%, for example, is still growing exponentially. And economic growth is still largely a measure of the acceleration of entropy–how much faster are we turning resources into pollution. He advises figuring out ways that periods of slow or no growth OK, because it will have to be.

Exponential growth really is counterintuitive. Here’s the way he describes it:

Imagine you are going to grow a test tube of a bacteria, starting with one bacterium at 8 AM and ending with a full test tube precisely at noon. The bacteria grow by doubling–a kind of exponential growth–each second. So at the end of one second we have two, after two seconds we have four, after three seconds we have eight, and so on. That being the case, at what time will the test tube be one-half full?

Right. Precisely one second before noon. And two seconds before noon it’s a quarter full. Three seconds is an eighth, four seconds a sixteenth. At 11:59.55 AM, the tube is only 1/32 full. Imagine being a bacterium in the tube at five seconds to noon. It would seem more crowded than usual, but look at all that space to go, and we’ve been doubling like this for almost four hours! There may be a problem in the next few days, but certainly not in the next few seconds–exponential growth is probably also counterintuitive for bacteria.

Posture: One Size Does Not Fit All

How should I stand if I want to stand in good posture? The answer I got from many, many sources–books, clips, websites, people–was some version of this: Tuck your tailbone under a little, imagine your head is being lifted, then hike your shoulders up a little, roll them back, then drop them down all the way in that back position. There are some minor variations out there, and some bigger ones–Esther Gokhale, for example, my mom’s favorite posture guru, is against tucking pelvis forward. “Ducky butt, not tucky butt!”

It was a bit of a revelation when my physical therapist, Shannon, gave me my first set of personalized instructions on my posture. I am to roll my shoulders up and back, but not down! I said “You are the only person who has ever given me that instruction. Why shouldn’t I drop my shoulders down as far as they go?” She explained, using a skeleton hanging in her office, how, while that’s true for many people, they way my shoulder blades and spine where out of whack, and because of which muscles are too long and too short from misuse, I need to bring my shoulders up. And I need to bring my ears in line with my shoulder joints. And I can tell the proper tilt of my pelvis based on what gives me the most height. Try it–reach up and move your pelvis and see what position lets you reach the highest. That’s the position for you.

After thinking about it, it seems obvious. Why would anyone think they could give me effective advice about my body without interacting with my body?

The Definition of Middle Age

Posted by Nathen under age, aging, definitions, middle age
[4] Comments 

As I approach it, the exact day I enter middle age has become more salient. Reanna routinely refers to people in their late 30s as “middle aged” and I feel taken aback. Since I’ve been thinking about such things, I’ve thought of the 30s, at least, as just plain old “adult.”

I am 39, a couple of months from my 40th birthday. When do I hit middle age?

Ah, that’s what I thought. I turn middle-aged at the end of this September.

Funny, the same website gives five more years, just by adding a “d.”

  • Middle age is the period of age beyond young adulthood but before the onset of old age. Various attempts have been made to define this age, which is around the third quarter of the average life span of human beings.  – en.wikipedia.org/wiki/Middle_age

I first misread this one as “middle third,” somehow, which liked–very intuitive. For men in the US like myself, however, whose average lifespan is 75.6 years, it places middle age between 25 and 50 years old. That means I’ve been middle aged since 1996. And that Reanna, as a Canadian woman with an average lifespan of 82.9 years, has been middle-aged since six months after her 27th birthday.

As my friend Julian pointed out, though, it actually says the third quarter: For men in the US from about 37.8 until about 57.7. It’s less intuitive for me, but lines up better with what people seem to mean by middle age.

I like that one as well. It may be the most accurate. Or perhaps this one:

  • middle age – (1) when every person you meet is only a composite of other people whom you have met. (2) a time when you’ll do anything to feel better, except give up what’s hurting you. (3) later than you think and sooner than you expect. (4) when a narrow waist and a broad mind begin to change places. – www.theabsolute.net/minefield/tmdict.html

The Only Good Thing About Being Out of Shape

Posted by Nathen under bicycling, biofeedback, cardiovascular exercise, exercise, healing, injuries

I am in a long, slow recovery from a sacroiliac joint sprain. I’ve just started being able to do more exercise than mild physiotherapy exercises, after almost nine months. I have to be careful, but I can do it. I am in the worst shape of my life, and generally I dislike it. The one nice thing, though, is how little I have to work to reach an aerobic heart rate.

In my normal shape, for example, bicycling is not a good choice for an aerobic workout. I have to push uncomfortably hard just to get to my minimum, low-level aerobic heart rate. [Which is somewhere around 108 beats per minute–60% of an estimated maximum of 180, since I can’t yet push hard enough to discover what my actual max is.] Now I can hop on my bike and hit an aerobic zone within a minute of riding gently. Pretty nice!

What Makes For a Good Coming of Age Ritual?

Posted by Nathen under adulthood, coming of age, Dune, Evan Imber-Black, Janine Roberts, manhood, men, Not Back to School Camp, rituals
[3] Comments 

I am piloting a new project this year at Not Back to School Camp called “On Becoming a Man.” I thought it would be a salient topic for many of the 13-18 year old males at camp. This is how I described it for campers looking for a project at camp:

“This project is for campers who are interested in becoming a man. It will include exploring the issues of what it means to be a man, the difference between manhood and boyhood, and the freedoms and responsibilities of manhood. Each participant will be supported in coming to a personal definition of manhood and, if they so decide, design a ritual entry into manhood.”

I’ve been thinking about the meaning of manhood a lot for many years, so I feel prepared for that part of the project. I am least prepared for the part where we design a coming of age ritual for each camper who chooses to have one. I’m doing some reading on it (Imber-Black and Roberts Rituals For Our Times) but not having had a coming of age ritual myself, I have next to no concrete examples. The gom jabbar ritual from Dune springs to mind, but I don’t have a poison needle or a pain box. (Plus I don’t think the NBTSC consent forms cover the possibility of death by poison needle!)

Did you have or have you witnessed a great coming of age ritual? Why was it great? Any horror stories? Thanks!

Three Umpires Asked How They Call Balls & Strikes

Posted by Nathen under epistemology, gender, lectures, lists, power, pronouns, Ralph Horwitz
Leave a Comment 

This was from the lecture “The Mismeasure of Man” by Ralph Horwitz at Stanford. It’s a nice way to distinguish between a few different ideas about our relationship to reality.

1) “I call them how they are.” This umpire believes that he has direct access to reality. In his mind, he just watches what happens and makes the call appropriately.

2) “I call them the way I see them.” This umpire acknowledges the limitation of his senses. He knows he may make a call that doesn’t reflect reality accurately because of his lack of direct access to reality.

3) “They ain’t nothing til I call them.” This umpire thinks he defines reality. Horwitz paints this one as the most arrogant, and he probably is. Whether or not this umpire thinks he has direct access to reality, he knows that he is the person who can say what we call a particular human/bat/ball interaction.

It shows a certain amount of self-awareness to be able to say what the third umpire said, which I admire. It is a kind of awareness that is necessary (though not nearly sufficient) for those of us with the inappropriate power to define the situations of others to give up that power. That is, no matter whether our power comes from race, gender, money, or whatever, we can’t give it up until we understand that we have it.

A note on gender in this post: Horwitz used the title of his lecture as a way to get in an apology about how much more research is done on men than women. He also used male pronouns for his umpires. Thinking that there are probably umpires of all genders, I tried to use “they” instead of “he,” “she,” or variations on “he/she.” It felt like bad writing so I went back to “he.” No offense meant, and if you want to take a crack at it, send me what you come up with.

When Nietzsche Wept

Posted by Nathen under 1880s, Bertha Pappenheim, books, endorsements, Friedrich Nietzsche, Irvin Yalom, Josef Breuer, Pandora, Sigmund Freud
Leave a Comment 

The first fiction I read after graduating from my Couples & Family Therapy masters program was the novel by Irvin Yalom, When Nietzsche Wept. I loved it and read it out loud to Reanna directly afterwards. I was fully engaged and deeply moved each time I read it. Yalom imagines a pre-Zarathustra Nietzsche becoming involved therapeutically with a mentor of Freud’s in 1882.

Before rushing out to get it, consider my caveats: I am a therapist and this is a novel about therapy. I am a fan of Yalom’s from having loved two of his clinical books, An Open Letter to New Therapists and The Theory and Practice of Group Psychotherapy. (The Group book split my cohort–most hated it. I never understood why. It was great.) I am also very interested in existential philosophy.

If you do read it, consider a doing a couple things that helped me enjoy it. I created a Pandora station for the 1880s out of Wagner, Mahler, and Strauss. It really shifted the tone of the book to be listening to the ultra-dramatic German music of the time. Second, all of the major characters are historical figures with images available online–Nietzsche and Freud, of course, but also Bertha Pappenheim, Lou Salome, and Josef and Mathilde Breuer. That was fun to see.

“Fight For Your Right” Revisited

Posted by Nathen under Beastie Boys, satire, video
Leave a Comment 

This is the funniest thing I’ve seen this year by far. I can’t recommend it to anyone who didn’t graduate within a few years of me (1989) but if you did, this is worth the 30 minutes. (This one’s not for you, Mom.)

I love the Beastie Boys making fun of their early days because before they became geniuses with Paul’s Boutique I thought they sucked and I hated their image. This makes all the misery of having to hear the songs on License to Ill fully worth it.

If you don’t know the Beastie Boys and are one of the 3-4 people who feel compelled to watch anything I post, here is the original video. The longer one above is supposed to have happened just after this one ends:

Paul Hawken Vs Ideology

Posted by Nathen under ideology, Paul Hawken, quotes, WiserEarth
Leave a Comment 

I like this anti-ideology rant by Paul Hawken at the end of his lecture, “The Long Green,” for the Long Now Foundation. He bemoans how humans have such a hard time seeing and taking into account new, unfamiliar information, especially when older, more familiar things, such as ideologies, are in view.

“During the span of the 20th century, big ideologies were worshipped. They dominated our beliefs of who we were, what was true, what was possible. Ideologies prey on our inner sensibilities. They stalk this earth, clad in a kind of existential armor: capitalism, communism, socialism fought all during the 20th century for control of our minds and it wasn’t pretty. And we were told, we were educated, that salvation would be found in a single system. But of course as psychologists and biologists that’s just complete poppycock. We know that stability and health can only be gained through diversity and not domination.”

Paul Hawken founded an organization called WiserEarth that is worth checking out. Here’s the blurb from their website: “WiserEarth helps the global movement of people and organizations working toward social justice, indigenous rights, and environmental stewardship to connect, collaborate, share knowledge, and build alliances.”
