Picking Your Brains

head explode

Dear LWON readers, I’d like to ask you a question.

Twice recently I’ve written about properties of black holes that blow my mind. In each instance, my inspiration was a detail from a movie.

First was Interstellar. The great gravitational grip of the black hole in that movie, as is the case for all black holes, distorts space to such an extent that objects on the side opposite the observer become visible. What blew my mind, though, was what happens when you take that idea to its extreme: One of the sources of light looming into view would be the far side of the accretion disk—the blindingly bright ring of debris encircling the black hole—in its entirety.

Next I wrote about A Brief History of Time, a documentary about Stephen Hawking. During a discussion of what you would experience if you were to fall into a black hole, a physicist says that time would appear to pass normally to you, but that the passage of time in the rest of the universe would appear to be speeding up. What blew my mind, though, was what happens when that idea is taken to its extreme: As you reach the very lip of the black hole’s event horizon, time would be accelerating at such a rate that you would witness the future of the universe in its entirety.

In both cases, however, what didn’t blow my mind was the underlying assumption: Gravity distorts space and time.

That concept used to be the extreme—a side effect of general relativity that would blow anybody’s mind. Now I accepted that assumption almost without thinking. Which, when I thought about it, blew my mind.

Snow Shelter

January 26 – 30

In guest writer Lesley Evans Ogden’s essay meditation, an Ontario girl builds a bond with the West Coast rainforest through her trail running.

We have come to understand that Craig does nothing in half measures. When he wants to understand the Younger Dryas, naturally he drags a sled onto frozen Lake Superior and spends a night – true to Pleistocene conditions – without a tent.

Christie gives us her favorite words and reports on a few we’d all rather strike from the dictionary.

Our fates are more indebted to our names than we know. Specifically the letters of our first and last initials.

When Helen lived in Japan, she listened to a pop group called SMAP – presumably an onomatopoeic name, akin to Wham! – and Friday’s launch of the Soil Moisture Active Passive (SMAP) satellite brought it all back.

What Does Today’s Possible Rocket Launch Have to Do With Japanese Pop Music? (I’ll Tell You: Very Little)

Delta II Rocket with SMAPFriday morning, if all goes well, NASA is launching a satellite with the name SMAP. As I write late Thursday night, it’s perched atop a Delta II rocket an hour up the California coast from Santa Barbara. It was supposed to launch this morning, but high-altitude winds got in the way.

Like so many things in NASA world, SMAP is an acronym. It stands for Soil Moisture Active Passive. The satellite is monitoring soil moisture, and it’s using both active and passive methods to do so.

I don’t know any more about the science than a quick perusal of NASA’s website got me, but I do know this: SMAP is a really silly-sounding name.

This is not a new opinion. I would like you to know that this is an opinion I have had more than 15 years to develop. This is not the first thing named SMAP to enter my life. Continue reading →

Sassy Smocks and Moist Panties

Words are a writer’s currency, and we each have our favorites. The first word I remember falling in love with was onomatopoeia. It had a satisfying rhythm, plus there was the delight of discovering, oh — there’s a word for that.

That joy of discovery was exactly what I felt reading Lost in Translation, a delightful new book by Ella Frances Sanders, who draws illustrations to help explain “untranslatable word from around the world” like trepverter (Yiddish for the perfect retort that comes to you later, when it’s too late), iktsuarpok (Inuit for the act of repeatedly going outside to check if anyone’s coming), cotisuelto (Caribbean Spanish for a man who insists on leaving his shirt tails untucked) and tsundoku (Japanese for leaving unread a book you’ve bought, perhaps piling it on top of a stack of other books you haven’t read).

English also has no true equivalent to my own favorite foreign word: gemütlichkeit, a German term that connotes the kind of warm coziness you feel when gathered around a fire with your dearest friends, perhaps drinking Glühwein. It must exist in some language, but I’m still seeking a word to describe a dog’s joy while frolicking in fresh snow.

Many of my beloved English words are onomatopoeic ones like flicker, boing, ripple, riffraff, guffaw and clusterfuck. As a kid, my favorite part of art class was the smock. Not the thing itself, but the occasion to say the word aloud, repeatedly. Smock, smock, smock. I don’t know why I love it, but I do. I also love sassy and saucy and, especially, sashay. I could say that word all day. Continue reading →

Hard Times in the Younger Dryas

By: | January 27, 2015

Lake superior with arrowThis time last year, most of North America was buried in an unusual cold period. The jet stream had hemorrhaged in early January and the Polar Vortex that usually sits atop the hemisphere like a halo came pouring down. Known as the 2014 North American Cold Wave, temperatures plummeted, particularly in the Northeast and Upper Midwest where double digits below 0 °F appeared for weeks. Lake Superior froze more solidly than it had in decades.

That’s when I went to the Superior shore of northern Wisconsin where nearby temperatures had reached -37 °F. If I wanted to get the feel of a cold spell, I figured this was my moment. At the time, I was writing about the Younger Dryas, a cold anomaly that hit the Northern Hemisphere 12,800 years ago and continued for a thousand years. The world at that point had been gradually warming, the Ice Age coming to an end. Suddenly, within the space of a decade, ocean currents reversed in the Atlantic, probably triggered by cold, meltwater flows coming off the shrinking Laurentide Ice Sheet. This reversal sent the world back into the Ice Age, and brought the end of the Clovis tradition in North America, the climate upheaval speeding up megafauna extinctions.

I don’t like writing about events without witnessing them, so I set off across frozen Lake Superior out of Ashland, Wisconsin, pulling a sled behind me with enough gear to last several days. I wanted a taste of the Younger Dryas. Continue reading →

Rainforest Drop In

LEO2I didn’t intend to fall in love with the rain forest. It crept up on me, imperceptibly at first, because the West Coast was never a place I had intended to stay. My roots were nurtured in the farmland, lakes and forests of Ontario before transplantation to the West, an alien habitat of strangely mild temperatures plus rain, rain, and more rain. I anticipated my westward migration as a transient phase. So I kept my emotional distance from this adoptive habitat, or so I thought. But recently, my strong attachment to this lush green place has become impossible to deny.

I spent my childhood in a land of predictable and obvious seasons. Summer was humid, hot, and thunder stormy. Autumn was crinkly, red-leaved and crisp. Winter was snowy and eye-icicly cold. And spring was muddy, rainy, and greenly profuse. So as I adapted to my new surroundings, one of the strangest, most disconcerting experiences was a momentary loss in time. Continue reading →

Cassandra explains why the flu shot is ineffective this year, what H and N stand for, how the virus outevolved the statisticians, and why to get the shot anyway.  A magisterially thorough explanation, and one feels better for it already.

Cameron has always liked maps, all kind of maps, maps that outline human influence on terrain, maps of holiday lights even.  But now she’s thinking about the dark places in between and surrounding the lights.

I got the flu shot, and then I got the flu.  I try to understand Cassie’s explanations and arguments but can see only seraphim and devils.  The flu is just flat-out medieval and the 21st century is very little help.

Helen’s lovely little turtles, fwip, fwip, fwipping their way down the beach to the brightest light around, the ocean.  And just like your cousins on Facebook, the turtles come back again full circle.

Richard watches the documentary A Brief History of Time. He finds out that seeing is not so much believing — because general relativity is seriously unbelievable — as it is understanding.  “Of course,” he says.
