The Earth’s Wobble is Veering

It doesn’t take much to get me going down a rabbit hole for facts. I’m on the hunt now, I’m on the trail. Harper’s published a factoid in their current issue’s Index which said:

Distance, in feet, by which the Earth’s axis of spin has shifted since 1899: 34
Estimated percentage of that shift that is due to climate change: 40
Harper’s Index, Dec 2018

Thirty-four feet? Really? How do they know that?  I do understand that climate change is occurring, however I also like to understand the facts behind statements. How do they know it’s due to climate change?

Start With the Wobble

First, we have to visualize the earth spinning on an axis and having a wobble.

No, not that kind of Wobble.

Start with the earth. It leans. What does lean mean? It is a matter of perspective. For example, many of us have been brought up to believe that north is up:

But, in fact, there’s no reason to view the world that way. People who happen to be standing in Antarctica don’t stand on their heads. From their point of view, the world map would look like this:

To Freeze or Not To Freeze

Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
–Robert Frost, “Fire and Ice”

With election trauma behind me and turkey recipes in front of me, I needed a little nudge in writing today’s entry, and my friendly neighborhood bloggers suggested Daily Word Prompts of chemical and freeze. Put them together and voila! today’s topic: cryonics.

Get Your Batsh*t Crazy Freezing Definitions Straight

First off, learn the distinction between cryonics, cryogenics, suspended animation. Cryonics is the science of freezing bodies with the hopes of future re-animation, after medical technologies have advanced to reverse aging or cure whatever ailed the body. Cryogenics is the branch of physics dealing with low temperatures. Suspended animation is inducing a cessation of body functions, perhaps through a low metabolic state, that preserves the body over an extended period of time. Suspended animation has been successfully extended to mice for a few hours, but not on anything as big as sheep or pigs, so unless you squeak, this is not a viable option yet.

How Many Things Do I Really Need to Do Today?

Has the artificial intelligence singularity already hit? If you’re familiar with the Terminator series, that’s where computer intelligence develops to a point where algorithms are able to learn and improve, which leads to A.I. self-awareness, which leads A.I. to determine that it’s more useful than its human creators. Ergo, humans are unnecessary, and the manifestation of computing power turns into Arnold with the sunglasses, Hasta La Vista, Baby!

Maybe we’re already there. There is a raging (interesting) debate between philosophical technology camps about when or if the singularity will occur. In the abstract, perhaps it’s forty years away. In reality, though, aren’t we already shaping our lives around technology rather than the other way around?  My wife likes to joke that we have to “give our lives up to the googles.” But, seriously, haven’t we tacitly agreed to let those little devices run things?

To Do Lists That Don’t Make Us More Productive

I like a good To Do list, although I’m often over-ambitious and put more things on it than I can complete. After I stopped punching the corporate clock, I wanted a program to help me keep track of the projects I want to do at home. I fell in love with ToDoist, but recently the romance has soured.

One of the features of ToDoist is that you define how many things you want to accomplish each day, and it tells you Congratulations when you completed them. Action items are now a game. Hit all the targets, and you win! Or, get a notification, if you don’t. You have only two hours left to complete your five tasks. If you don’t update for a few days or go on vacation, you get a depressingly long Overdue list.

Suppose I have a day where I do One Big Thing that eclipses all others? I still get dinged for not doing four more, and then I lose my “streak” of days which affects whether I’m rated as an Expert or Apprentice. So I find myself doing things like, after the fact, adding “Grocery Store” or “Go to Mailbox” as a task.  I wonder whether this is really adding to my “personal productivity,” and, by the way, when did people need to run themselves like a business, anyway?

Erratic Like a Fox

“Why did he do that?”

“How could she?”

“What was she thinking?”

Tsk, tsk.

We’re living in an age where we cheer the eccentric and boo the erratic, in equal measure. Same as it ever was.

I was prompted to write a post for today’s Word-of-the-day challenge about Erratic.  I immediately reflected on the past couple of weeks. Elon Musk and the joint. Serena pointing at the ref. Madonna, always controversial. What do they all have in common? Success, you motorscooters! Success, despite their seeming erratic behavior. Success which comes from their innovation, talent, and unpredictability.

The Erratic 85.49% Winner

Serena is the greatest tennis player in history. Winner of 23 Grand Slam titles, she now competes against teenage athletes who grew up idolizing her. About to turn 37 years old, with an infant at home, she blazed into the Wimbledon and U.S. Open finals. Although she lost both finals, her power and presence were remarkable given her recent circumstances. Continue reading “Erratic Like a Fox”

Drinking from the Firehose…

…and Other True Cliches…

I shouldn’t be writing a blog today. I’m having one of those weeks.  I thought I was done with being overbooked, since I sledgehammered off the corporate shackles from my old middle-management life, but that was a silly idea. As human beings, we can never eliminate stress from our lives entirely. Besides, it’s good for me. If I can make it through the week.

When I first started teaching, the temporary, part-time gig was enticing. A handful of classes, a manageable load of students, and material that I could master. Juggling a schedule with multiple classes has turned out to be less easy. Classes get cancelled; students don’t show up and then too many show up; the door is locked. Stuff happens, like in any job.
