It’s a rainy Sunday afternoon and I’m in the mood for a little fun. If you are too, check out this trick over at NPR. Mr. Man and I just tried it and it is exactly as cool as it looks.

Mwahahahaha! Oh, and the idea to use this technique to ease childbirth is fascinating too.

(today I bring you a dispatch from the wilds of suburbia)

I just mowed the front lawn. I hate mowing. We have an electric mower that’s great, it’s a small yard, no big deal, but it is not my cup of tea.

English estates popularized lawns, but it took America to democratize the things. I’ll cite a few lines from a nineteenth-century book based on Frederick Law Olmsted‘s work (via this excellent article by Michael Pollan), but the real push for lawns started in the 1950s.

“Let your lawn be your home’s velvet robe, and your flowers its not too promiscuous decoration… A smooth, closely shaven surface of grass is by far the most essential element of beauty on the grounds of a suburban house.”
— “The Art of Beautifying Suburban Home Grounds,” Frank J. Scott (1870)

Pretty? Sure, if you like uniformity. But in terms of land use, water use, and pesticide chemical use, lawns are terrible for the environment. They are also a massive time suck. Don’t get me wrong, I love Olmsted’s take on keeping nature in cities and improving society through physical design, etc. But there has to be a better way.

We planted a clover-grass mix (yes, on purpose:), but by the time the clover is tall enough to flower, the grass is twice as high and seeding. The neighbors have beautiful, chemically-induced perfections of green. They look askance at our “grass plus” mix, and at the way we wave the weed control van on when it comes around.

And so to keep the peace, I mow. Even when the clover is flowering and the bees are buzzing and can’t understand why I would take away their glorious buffet. I’m not sure why either. I ask the bees for understanding, and I mow in slow motion to give them time to leave the all-you-can-eat-restaurant-turned-food-desert and under my breath I’m asking myself “What’s the flipping point?” I mutter it as I mow the clover, the edible wood sorrel and lamb’s quarters, and the wild strawberries that spring up under the bushes.

Except I don’t say “flipping.”

We’re still looking for ways to shift our lawn to something more useful, but it’s a process. Want to save time, money, and the planet? Here are a few ideas to get you started.

The back yard doesn’t get as much sun, and only patches of clover flower there. I let them grow anyway.

Today is the autumnal equinox, or the official start of Fall. I like to think of it as the Universe giving all of us here in the Northern Hemisphere a pat on the arm and a kind word to prepare us for that whole Winter thing.

What is It saying? When it comes to the grand workings of the Universe it’s always difficult to be sure, but I imagine the conversation goes something like this:

“Now now, Winter’s still a ways off and hey, you had a good Summer, right?”

(inarticulate mumblings about sunburn and too many mosquito bites)

“Well, not to worry. We know Winter is hard so We try to ease you into it with the likes of apple pie and hot cider.”

(sniffles, with a muffled acknowledgement that pie is really quite nice)

“And remember how much you liked that new recipe for spicy beef stew? Pull yourself together, dear, it will be fine.”

For those who prefer a slightly more technical explanation of the experience on which we are all about to embark, a few more details…

Solstice: occurs when the Sun is the farthest away from the celestial equator, or the imaginary line above the Earth’s equator. This happens twice a year, around June 21st (when it reaches the northernmost point) and December 21st (when it reaches the southernmost point).

Equinox: marks the time when the Sun crosses the celestial equator. Day and night are (close to) equal length. This happens twice a year, around March 20th (vernal) and September 22st (autumnal).

Would you like to know more? Check out Time & Date or Royal Museums Greenwich or EarthSky for additional information, helpful diagrams and fun facts (like Chichen Itza’s Snake of Light).

I do love pie and cider and crisp autumn days and bright red leaves. Today I’m also grateful that marking such astronomical events no longer requires human sacrifice, for the word “phenology,” and for the reminder that in spite of everything, we all see the same sky.

Will the sky be clear enough to see the eclipse? This question was on the minds of many people attempting to view yesterday's solar eclipse. The path of total darkness crossed the mainland of the USA from coast to coast, from Oregon to South Carolina — but a partial eclipse occurred above all of North America. Unfortunately, many locations saw predominantly clouds. One location that did not was a bank of Green River Lake, Wyoming. There, clouds blocked the Sun intermittantly up to one minute before totality. Parting clouds then moved far enough away to allow the center image of the featured composite sequence to be taken. This image shows the corona of the Sun extending out past the central dark Moon that blocks our familiar Sun. The surrounding images show the partial phases of the solar eclipse both before and after totality. Image Credit & Copyright: Ben Cooper

In honor of today’s eclipse, I’d like to spotlight this piece on Annie Jump Cannon from the funny and informative site Rejected Princesses. Their tag line?
“Women too Awesome, Awful, or Offbeat for Kids’ Movies.”

Hee hee! If you’re interested in quick, clever portraits of some of the most interesting women in history, Rejected Princesses is the site for you.

(Related aside: I’m also pretty sure that popular movies are selling our kids short.)

Why Annie Jump Cannon? Because she fell in love with the stars at a time when most women were only expected to fall in love with homemaking, and then she went and did something about it.

Born the same year President Lincoln issued the Emancipation Proclamation, she attended college at a time when few women did, and then worked at the Harvard Observatory as a “computer.” (If you’ve seen Hidden Figures, you know what “computer” meant lo those many years ago. If you haven’t seen Hidden Figures, I highly recommend you do, stat!) She excelled at Harvard, classifying stars by the hundreds of thousands and building a spectrographic star classification system still in use today.

Ms. Cannon has been called The Queen of Modern Astronomy, but also brought a useful perspective to more terrestrial concerns. And while earthly challenges must continue to occupy our thoughts and energies, one quote in particular seems appropriate for our current times:

“In these days of great trouble and unrest, it is good to have something outside our own planet, something fine and distant and comforting to troubled minds. Let people look to the stars for comfort.”

If you don’t already have eclipse plans but you’re interested in a once-in-a-century astronomical event, NASA has a great site. They’ll help you enjoy the eclipse with everything from maps, safety, activities, DIY pinhole viewers, what to do if you don’t have a viewer but still want to see the event, and more.

Like most people I’ll be outside the path of totality, but we’ll still get 65% coverage. Well worth putting together a pinhole viewer… Oh look, here’s one I just happen to have, hacked together from a shoe box, legal paper, the sticky bits of reusable adhesive you find on the back of various packages, and a phone for easy photo taking:) I’ll cut the lid off to better control the distance between pinhole and paper, then hope for clear skies!

Eclipse: Who? What? Where? When? and How? is a good place to start, or check out the Eclipse Kit for all most of your eclipse party needs (beverage of choice not included:)

Have fun!

What am I doing this fine Saturday morning? Why, playing with Google’s newest entry into the Made with Code catalog, Coding with Wonder Woman.

Made with Code is Google’s push to keep girls and women active in Science, Technology, Engineering and Math. Girls are awesome. Sci-tech is awesome. Together, they make an awesome sandwich.

Of course, boys are awesome too (hello, most excellent nephew!), but they aren’t facing this less-than-awesome prospect:

Yeah, that’s just… no. We can do better. If we’re going to tackle the long and growing list of environmental, social and technical challenges in the world, we need everyone’s brain parts. And not in a night of the undead hunger sort of a way.

There are a lot of intro to coding resources on the web, but this one is fun, free and lets you fight bad guys with a magic lasso and a big-bad sword. So girl or boy, man or woman, child, teacher, parent or otherwise curious mind, if coding looks like fun but you don’t know where to start, this may be the game for you.

(Haven’t seen the movie? Recommended!)
