Procrastination is our friend.

The clutter that defies my attempts at de-cluttering is usually the result of either of three things:
  • being in-the-middle of a project or idea, or
  • being completely stumped as to how to disperse the particular object, or
  • pure procrastination
In the second category, I had a few problems I’d mentioned before: my cacao bean roaster, my mother’s samovar, and my audio cassettes. The cacao bean roaster ended up on my friend Judith’s mantle, where she’s trying to figure out what to do with it. The samovar and audio cassettes are still my problems, still taking up space while I … procrastinate.


BUT, every now and then, procrastination is our friend! Every now and then, failure to de-clutter means you still have the thing you were considering giving away, and you need it!

No, I still don’t need a samovar or audio cassettes. Does anyone?

Way back on June 5, 2012 was the last Transit of Venus. This is when Venus passes between the Earth and the Sun and you can see the little black dot of Venus moving across the face of the Sun. If you missed it, sorry: the next one isn’t until 2117. It’s a very big deal if you’re trying to measure the distance from the Earth to the Sun, and history is full of expeditions to observe it around the world.

So there was no way I’d miss it on June 5, 2012, when the University of Alaska Anchorage Planetarium set up telescopes and had us all watching the skies. They gave out special solar sunglasses.

Desk space is the most valuable real estate in my office. Papers and articles, mail and bills need that space. Desk space is the space where items of immediate concern – items of current necessity – fight for attention. Desk space is the place where urgent items are at risk of missed deadlines if they get covered over. Desk space is my High Priority Zone.

The cardboard solar sunglasses have been sitting on my desk since June 5, 2012.

Every time I’d pick them up or shift them around because they were in the way, I’d know they really needed to be relocated elsewhere. But then I’d ask myself: Where do cardboard solar sunglasses go so I’d be able to find them when I need them?

I couldn’t come up with a single obvious and apparent location.

Without an obvious and apparent location, you run the risk of not being able to find things when you need them. I just barely stumbled across the TSA luggage locks when I needed them, but where-oh-where is the large-size label I was saving for the cover of that notebook? Or the short extension cord? If something doesn’t come as a whole family of objects – if it travels solo – it can go astray.
But Monday is the Total Eclipse of the Sun, and I am ready! Sunglasses are apparently sold out all over Anchorage, and FAKE ones are being offered for sale online, but I just had to shift a few papers aside, and there mine are! They spark a lot of joy! For now, the joy of de-cluttering has been replaced by the joy of NOT de-cluttering.

Yes, this sets back the de-cluttering cause significantly, and I know those sunglasses really do need a permanent home, but that can wait till after 10:14 a.m. on August 21.

Our Expanding Universe

I get it! I understand! I had to reach my Third Third, but I finally have the answer. So, what’s the question?

It’s about the Big Bang and how our universe is continuing to expand. I get that. (Stay with me; it’s more than a metaphor.) But when I was in New York City, I blogged about this problem I had:
In the Hayden Planetarium show “Dark Universe,” Neil deGrasse Tyson (one of my heroes), said that when things move away from us, their light waves “redshift” [as if we’re seeing tail lights], that from our position in the universe, everything is moving away from us. He distinctly said that from ANY point in the universe, everything is moving away from it. How can that be? Something has to be in front of something. In fact, one of the panels mentioned the galaxy “in the foreground,” so wouldn’t it be chased by the galaxies in the background? This bothers me.
Then the UAA Planetarium featured a special event in which Michael Turner of the University of Chicago delivered a program in the Adler Planetarium and we got to watch it live here. His topic was “From the Big Bang to the Multiverse and Beyond,” and he said the exact same thing I’d heard in New York.

By now I was truly bothered, but with the audacity of my Third Third, I decided to get to the bottom of this. I wrote them both emails and asked for an explanation. I got two replies, and now I get it! Years of planetariums and reading and I just didn’t have my head wrapped around the universe just right.

This is the answer from Dr. Turner, Director of the Kavli Institute for Cosmological Physics:
“The expansion of the Universe is NOT galaxies moving away from an explosion; but rather, an explosion of space with galaxies being carried along. Think of a rubber sheet (space) decorated with my hand drawn galaxies being stretched; that is the big bang universe. Space expanding in all directions and galaxies being carried along.”
And this from Dr. Or Graur of the Hayden Planetarium:
‘The problem here is with the word “moving.” When we talk about the universe expanding, we mean that distances between objects are getting larger. That creates the illusion that everything is moving away from you, and is why you’ll see this effect no matter where you are in the universe. But it doesn’t mean anything is moving, only that the distances are getting bigger.’
Aha! It’s not that we’re moving; things are just enlarging around us. Something in my world – my universe – just got more explicable. Something was illuminated and made sense on a foundational level. My understandable universe expanded!

This is a Helen Keller moment – the awareness that the word “water” is what water is. I’m sure you know what I mean. Maybe the expanding universe is not your thing or maybe you already understood about space and expansion; but you know that giant light bulb moment. The world shifts and makes sense. Aha!
I feel sort of pumped about emailing those guys. This time, I didn’t just give up and resign myself to my little vexing confusion – how many times have I done that! When you’re in your Third Third, “now or never” is an even less flexible ultimatum.

Now I’m deciding what other things I need to clear up.

LOTS of food for thought

When my daughter started school and when she went to college, there was always just one thing I was watching out for: was her curiosity still intact? Was she still finding the world interesting and was that interest still motivating?

I ask the same of myself, but especially now in my Third Third. The idea of stagnation is anathema to me, and now it’s compounded by believing that curiosity fights off cognitive decline (and seeing my mother in New York leaves me especially worried about that).

Mostly, I’ve always been curious. My brain is like a garbage disposal that can’t turn off. With no food in it, it just whirls and grinds away relentlessly but pointlessly. But with food – and New York City provides SO MUCH food – it’s useful and productive. It processes.

Here are some of the things I’m wondering about now. I haven’t been able to sleep until I Google some of them, but I’ll probably need to check some books out of the library.
  • In the Hayden Planetarium show “Dark Universe,” Neil deGrasse Tyson (one of my heroes), said that when things move away from us, their light waves “redshift,” that from our position in the universe, everything is moving away from us. He distinctly said that from ANY point in the universe, everything is moving away from it. How can that be? Something has to be in front of something. In fact, one of the panels mentioned the galaxy “in the foreground,” so wouldn’t it be chased by the galaxies in the background? This bothers me.

     
  • During World War II, book publishers turned out 123 MILLION Armed Services Editions of little, skinny (but complete) versions of titles so soldiers could fit them in their pockets. The author of A Tree Grows in Brooklyn received 10,000 letters from grateful GIs (according to the New York Public Library program by the author of When Books Went to War). I want to find a skinny book!
  • From the American Museum of Natural History “The Secret World Inside You,” I discovered that a baby’s passage through the mother’s birth canal is crucially important to bathe it in valuable bacteria. Doctors are now looking at swabbing babies born through Caesarean section with the bacteria to prevent things like asthma and food allergies. I am SO GLAD I gave my daughter bacteria!

  • In the Cooper Hewitt Smithsonian Design Museum, I saw Jenny E. Sabin’s gorgeous, knitted pavilion. She made it of solar active yarns so it lights itself up at night. It is truly spectacular and my drawing wouldn’t do it justice so you can click through for more photos here. Just imagine being under it.
  • I learned about Voronoi polygons at the Museum of Mathematics on Pi Day (3/14/16). If you have a few points and you divide them up so a region (shaped like a polygon) is closest to one point than any neighboring one, they’re Voronoi polygons. A bazillion kids on a field trip danced on a floor that changed shapes and colors every time a kid moved. John Snow, who identified the water pump that spread cholera in London (another hero of mine), used these to find the pump. He must have plotted all the deaths and saw they were closest to that one pump.
  • A Jewish man in Georgia, Leo Frank, was sentenced to death for murdering a young girl. When evidence showed it couldn’t be him, the governor commuted the sentence, but a group kidnapped him from prison and lynched him. The group included the former governor, mayors, and state legislators. They were never punished, and they subsequently revived the KKK. I learned this at the Museum of Jewish Heritage.
I realize this is all pretty boring, listed out like this. I learned from brilliantly designed exhibits, with things you could touch and see, bright graphics and clear visuals. My New York experience is mostly real life and real culture, and I pick up most of what I learn through osmosis (although I manage to forget that the D train is an express and I keep ending up on my way to the Bronx with no way to get off).

But these museums, these programs, these institutions are smoldering hubs for curiosity. I am really, really good at unearthing every program, talk, exhibit, tour, or event I can; the table is littered with flyers, newspapers, programs, and handouts.
I am a glutton and curiosity hog, New York is a never empty banquet, and I only have a month to feast.

Of galaxies and glaciers

Not only is the earth not the center of our solar system, but our sun is not even in the center of our galaxy. Today I learned that our Milky Way galaxy is called a “barred spiral” galaxy: in the center is a bar-shape of stars. Our sun isn’t even in the two biggest arms that spiral outward; it’s in a lesser one called the Orion Spur.

We are a teeny-tiny bit amongst billions and billions of stars, and we are back in the wings, on the periphery, not center stage. I find this reassuring.

Right after I moved to Alaska, I went kayaking in Glacier Bay. It was an astounding trip: beautiful, blue glaciers; the stark black-and-white landscape that I love; utter quiet. I stayed out long enough to forget about coming all the way back.

At one point, I spotted a dirty glacier. It was blue, but it had lots of debris and dirt and was really splotched and marred. At first, I felt as if it were some horrible aberration in the universe, a defective glacier. And then I thought, This glacier is so huge, and its stain is so huge, and still it’s powerful. And this is me, and my defects are huge, but compared to that glacier, they are infinitesimal. My problems are insignificant!
I have to remind myself of this every now and then so I check out astronomy, where I am reduced to insignificance again. I am a major fan of the UAA Planetarium; as members, we get to attend the shows for free. What I like is that the shows come with real, live, local scientists who are actually doing research that the films introduce.

I once was a physics major. Eventually, I stopped understanding it but remained in awe of it, so I switched to philosophy of physics. The questions still enthrall me so I take Olé classes taught by Travis, a UAA astrophysics professor. Today, Betsey and I agreed that Travis is so clear and comprehensible, we actually understand general relativity until we get home.

So the current class is about finding life on other planets, and it reminded me of another class with Travis. He had said that life would not look like little green men, but we were looking for the elements and conditions that might support life. He spent a whole class talking about how we might go about categorizing, identifying, finding those elements. Finally, one woman raised her hand and said, “Well maybe that’s not the way to go about it. Maybe we should first figure out what the little green men require and then focus on finding those places that might support them.”
Blows your mind, too, doesn’t it?
