Plugging In

Two weeks ago, for the first time in 15 years, I flushed the toilet inside my house.

This — and by “this” I mean the 15 years of non-flushing — was not quite as gross as it might sound. Until very recently, my family and I lived off the electrical grid in rural Colorado, in a straw-bale house with solar panels, minimal plumbing and a limited water supply. To conserve electricity, we had few appliances, and to save water we used a composting toilet (we had what is delicately called a honey bucket). It was fun and cheap and wonderful in unexpected ways — even the honey bucket had its charms — but over the past year it became clear that my family needed a less isolated place to call home.

Our off-the-grid life and our move is chronicled in this new piece from the public-radio show BURN, but to make a long story short, we rented out our straw-bale nest, bid tearful goodbyes to our neighbors, and moved to the middle of a still rural but larger town in the Pacific Northwest, close to both family and old friends. And then we promptly plugged back into the grid.

Conversation: Girls Reading Boy Books

3588551767_73ede01262_zAnn:  May I introduce my friend and colleague, Sharon Weinberger. She once wrote a book about her trips to the world’s various nuclear test sites and it sold reasonably well, probably to boys.  But recently somebody else’s book, The Girls of Atomic City: The Untold History of the Women Who Helped Win World War II, hit the best-seller list, and Sharon told me she was possessed by the Great Green God of Jealousy.  That’s a well-known side effect of having written any book ever, but I think in this case it’s more complicated.  Dear Sharon, can you explicate?

Sharon: The Girls of Atomic City is clearly an appealing book so I don’t begrudge the author her success.  But in this case, I think my jealousy is about her ability to connect with female readers. I write on science and national security, and when I look for examples of books in this area that seem to have crossed the gender barrier, I find books that are about family life or wives of scientists. Another recent example, perhaps, is the Astronauts’ Wives Club, which chronicles the wives of the men who had the “right stuff.”  This goes back to the issue you raised of gender in scientists’ profiles: why do journalists ask scientists who are women about their childrearing habits? Perhaps we need to ask another question: why do we see women gravitating toward books about childrearing habits?

Ann:  Because our stupid binary culture can’t handle anything more complicated?

Digits of the Devil

AnticrepuscularRaysAschwanden 300x402On Sunday evening, I was standing in our orchard watching the sunset when I turned around and saw a strange beam of light that appeared to rise from the east, directly opposite the setting sun. Crepuscular rays or “God’s Fingers” are pretty common around here, but usually these majestic light rays emanate from the sun. How could a sunlight radiate from a point opposite the sun?

I basked in this beguiling mystery for approximately ten seconds before my husband informed me that it was no mystery at all. “It’s just an optical illusion caused by those clouds,” he said, pointing to the storm clouds above that had been spitting out dry lightning for the past 20 minutes.

Upon further investigation, I realized that he was right. The rays we were seeing were actually parallel lines, created by sunlight pouring through gaps in the clouds. But when these straight, parallel lines get projected onto our spherical sky, they take on a circular appearance and seem to converge on the horizon in the same way that railroad tracks appear to intersect in the far-off distance. This photograph taken by the Expedition 29 crew at the International Space Station in 2011 offers a more revealing perspective. Continue reading

Why did the boy throw the butter out the window?*

wikimedia-monarch-Dreamdan 500x333Right now, the butterfly might be coming out. Or it might not. On Thursday, my son’s preschool teacher said that Friday would be the day. On Friday, she said she hoped it would wait until Monday. She and the kids have been marking off the days since the monarch caterpillar stopped munching milkweed and spun its chrysalis.

The monarch’s chrysalis is green with a few yellow spots like a crown near the top. It hangs on the inside of a soft-sided mesh cage. Every time someone says the word butterfly, it seems, at least one kid jumps up and checks to see whether it has emerged. Waiting is very, very hard. Continue reading

The Last Word

June 10 – 14

This week, LWON got a new PoLWON! (not pictured at left) Her name is Roberta Kwok and you may remember her from her intriguing guest post about how investigators solved a grisly and tragic car crash. Roberta kicked the doors down with with an amazing primer on the history of the exoplanet hunt.

Tom told us why it’s not the popcorn that makes you fat but the bag. And don’t skip the comments, in which Ann reveals the secrets to perfect diy popcorn.

Ann also teamed up with Abstruse Goose to make fun of poison ivy. (Patronising poison ivy in mid-June. Surely not a brilliant idea.)

Whatever you do, do not miss Richard’s two part series on the disturbing science of magic.

See you next week!

Chasing Transits

CELESTE: How long this time?

LE GENTIL: How long will I be gone? Three years. I swear to you, Celeste, on everything that’s holy: three years, no more.

CELESTE: What if you miss it?

LE GENTIL: The transit? I won’t.

CELESTE: You missed the last one.

Transit of Venus

Venus (the small dark dot) crosses the Sun.

That lovers’ quarrel comes from Transit of Venus, a play by Maureen Hunter that chronicles French astronomer Guillaume Le Gentil’s doomed quest to see Venus crossing the Sun. Le Gentil embarked on a voyage to India in 1760 as part of an international effort to observe the transits of Venus, which occur in pairs roughly once a century. By watching these rare celestial events from far-flung points on the globe, scientists hoped to calculate the distance from the Earth to the Sun. Continue reading

New Person of LWON: Roberta Kwok

RobertaWe are overjoyed to announce that Roberta Kwok has become the newest person of LWON (or LaWONian, as some of us like to say).  You’ve seen her here before. Her first guest post explained how a study to detect traffic patterns gave investigators new insight into a fatal car crash. Elsewhere, she’s written about synthetic DNA, mysterious fossils, and how plants and animals get their shapes. Her 2009 narrative about some astronomers who tracked a meteorite in real time won the the American Geophysical Union’s Walter Sullivan Award for Excellence in Science Journalism. A person of many talents, Roberta also writes beautiful fiction and she once worked as a software engineer in Silicon Valley. We’re especially grateful for her computer savvy, since she has agreed to help keep the technology behind LWON running smoothly. Roberta hails from Calgary but recently relocated from northern California to Seattle, where she’s trying not to think about the coming rainy season.

Welcome, Roberta!

 

It Wasn’t The Junk Food That Made Me Fat – It Was The Bag

2145502208_d0c8a216ae_bWhen I think back on the formative moments of my youth, it’s hard to top the Canada-Wide Science Fair of 1980. It was there, in Thompson, Manitoba, that I first truly experienced the transformative power of science to make daily life richer, better, more rewarding. No, it wasn’t my own engagement with the scientific method and R&D – sure, the physically accurate cloud simulation device my sister and I designed and constructed was nifty, and the experience helped shape my future education and blah blah blah. But it was the junior science on display in the booth next to ours that really changed the future for me.

I don’t remember his name, and I can’t recall where he was from. But I do remember his schematics almost well enough to sketch them for a patent application. Our neighbor’s popcorn popping optimization research went on to win first place in our division, and deservedly so. By painstakingly varying a score of conditions, from oil type and volume and preheat time to advanced notions such as pre-soaking the kernels and using a pressure cooker, my adversary simultaneously anticipated and outdid the Cook’s Illustrated trial and error approach to kitchen science. (The magazine launched the same year.) Continue reading
