Eclipse thoughts

Thinking about today's lunar eclipse, I was wondering  what it would look like if you were standing on the moon looking at an eclipse of the sun by Earth. Sure enough, someone has painted a rendering of it - a red rim around the Earth that would last for hours.
It is quite a coincidence that the moon is almost exactly the right size to cover the sun as seen from Earth.
Apparently the moon can appear slightly larger or smaller than the sun depending where it is in its elliptical orbit around Earth, hence there can be a "supermoon" solar eclipse or a "micromoon" solar eclipse.
That got me thinking, what would an eclipse of the sun by the moon look like if you were on the dark side of the moon? It would be a narrow path of totality about 60 miles wide, and there would be a red penumbra around it. Do you think you'd be able to see it with the naked eye if you were standing on the moon? Here's an animation of the path of totality:

Building a highway inside a tunnel under Seattle's waterfront

A lot of steps, a lot of concrete, a lot of waiting around 28 days for concrete to harden, and a lot of the tunnel cross-section used only for escape routes because they're making a square roadway in a round tunnel..
The next video explains how they keep the tunnel from collapsing behind the tunnel boring machine, and how they keep water from leaking into the tunnel by using "tail seal grease" injected between wire brushes at the rear of the TBM.

Transaqua: The Project that Can Transform Africa




Diverting 3% of the Congo River, the third largest in the world, would replenish the shrinking Chad basin and revitalize farming in a vast area of central Africa. Italy is involved, being motivated by the prospect of an economic turnaround stemming the flow of refugees reaching their shores, while China is interested in cultivating an economic partner.

Traffic flow measured on 30 different 4-way junctions

I thought you'd be interested in these projected numbers of cars getting through various intersection designs. Have you heard of the diverging diamond interchange, at 3:20 in the video? It crosses lanes of traffic before the intersection to decrease the number of points in the intersection where head-on collisions can occur. Apparently they're starting to build those near Seattle.


Some of the later designs after that in the video are quite elaborate and unusual. It's too bad they don't factor in the construction cost which would be a big impediment to improving congestion.

Quotations from "We were eight years in power."

[Civil war:] But the fact that such carnage had been wreaked for a cause that Ulysses S. Grant called "one of the worst for which a people ever fought, and one for which there was the least excuse" invited the damnation of history. Honor is salvageable from a military defeat; much less so from an ideological defeat, and especially one so duly earned in defense of slavery in a country promised on liberty. p73.

I found this documentary was well researched and answered a lot of questions about the challenges of building the world's largest bridge.

Some of the numbers are staggering. Each 5mm cable strand can hoist the weight of 3 cars, and the bridge cable contains 27,000 of these strands.

I wondered what efficiency do plants have in capturing solar energy

Photosynthesis is less efficient than solar panels. According to the Wikipedia page on photosynthetic efficiency, typical plants have a radiant energy to chemical energy conversion efficiency between 0.1% and 2%. Most commercially available solar panels have more than 10 times this efficiency.

Kiribati: a drowning paradise in the South Pacific

Interesting documentary on an atoll community struggling to maintain their way of life despite the inexorable sea level rise. Efforts to educate and find sustainable drinking water solutions are described. A palpable fear of losing their cultural identity if forced to leave their homeland drives these people to find solutions they can all buy into, like turning palm sap into marketable dry sugar.

The Parent Trap

Funny satire on the futility of spending on our kids activities.

The Parent Trap

I went out to get my paper this morning and found my neighbor Dalton instead.
He was slumped on my stoop, looking as though he'd slept under a marching band. His eyes sported five-pound bags, his right hand was bandaged and bloody, and his face was sunk like a bad soufflé.
"My God!"I said. "What happened to you? You look like a 20-car funeral"
"Youth lacrosse happened to me," he grumbled. "The Competitive Elite Lacrosse League. My little Ashley made one of those 'travel teams.' Pray it never happens to you, dude."
He explained."See, I really never thought Ashley was all that hot at lacrosse, and she's only 14. But when she made this competitive team, all the parents said it was a big honor. They said it's the only way to make your high school varsity, and it's the road to a scholarship, and it looks great on your résumé.
"I'm not even sure Ashley wanted to do it. But all of her friends made it, so she just had to do it. What was I gonna do? Tell my little girl no?
"Next thing you know, I'm writing a check for $1,500. Then it turns out, they practice or play seven days a week on these things. And it's clear across town, so pretty soon I'm standing on the sidelines every day of the week.
"My wife can't do it 'cause she has to take Justin to hockey every day. Why an eight-year-old nearsighted kid needs a 42-game schedule is beyond me. What is he, Wayne Gretzky? Plus there's pylon camp and forecheck camp and backward-skating lessons with his personal coach, Hans.
"So pretty soon I got no life. Family dinners? Forget it. Every meal is in the car--right-handed Taco Bell. I almost never see my wife awake. When I do, I have to ask for I.D.
"Then this lunatic lacrosse coach schedules an extra 6 a.m. practice every day. It's like the old bottle-feeding days. I'd be like, 'I got her last time. You get her.' And Denise would moan, 'I had to stay up for Midnight Madness last night. Your turn.' Then, at night Ashley is so tired, we end up doing her dang homework! And we're gettin' C's!
"Anyway,Ashley and I started flying to all these stupid tournaments--Dallas and Baltimore and, my God, Ottawa!--and every one is billed as 'the recruiting event of the year!' And do you know who we see at these tournaments? The same damn girls we used to play in our neighborhood league! Essentially, we're flying across the country to get our ass kicked by the same exact people!
"So I start talking to these girls' parents, and it turns out they don't really want to be there either, but their kids were saying we were going to do it, so they had to!
"But then my wife gets to talking to some other moms at Justin's slap shot workshop, and they say we're crazy if we don't have a 'performance-enhancement specialist' for our kids. So she signs them both up with one. Then she finds out most of these girls have 'recruiting consultants' who make highlight reels of kids and send them to college coaches. I'm like, 'She's 14!' And my wife is like,'You're gonna tell our little girl no?' Then we add a rating-service guy and a sports psychologist and a webmaster. 
"Well, what with me working half time and all this crap I'm paying for and all these trips,I had to take out a second mortgage. Denise can't work because she's spending every waking moment in a freezing ice rink, which makes her joints stiffen up.Luckily, Hans knows some New Age massage technique that makes her feel better.
"So now I'm getting no sleep, turning my stomach into a Dumpster and having less sex than a dead monk. But before I can put my foot down, my boss does. He fires me! And as he's firing me, he adds, 'By the way, the average lacrosse scholarship is $1,000, you putz!' So I punch him, and now I think my hand might be broken.
"I stomp out and go find Ashley to say, 'It's over.' And she goes, 'Whatever. I quit today anyway. My sports psychologist says you guys push me too hard.'
"Nice. So I go home to tell Denise, but she's not there. Three days go by. I figure she's at the Elite Competitive Hockeypalooza in Cheyenne. Turns out she moved in with Hans. Says she wants to be with someone who 'knows' her. Oh, and she really likes massages.
"So now I get home and somebody changed the locks! Probably the mortgage company, since I'm way behind.
"And do you know what I learned from all this, man? I learned that the most viciously competitive sport in the world is parenting.

Farmed Norwegian Salmon World’s Most Toxic Food

Don't eat fish. Fish farms feed with ground fish meal preserved with unstudied toxins and itself containing fish having high levels of PCB (thus concentrating dioxins, and other toxins.) This documentary really investigates down to the source for this information.

Perhaps an option is to take the fish farms into deep water, but this doesn't alleviate the problem of what's in the fish food.

Japanese Real Indigo

I didn't realize the labor of love entailed in dyeing fabric with indigo, or that it was both flame-retardant and antibacterial. It takes a year to prepare the dye and several days to dye the fabric. I found this a particularly interesting little documentary.

This documentary on wasabi is equally poignant. There's a tremendous pride in Japanese artisans that would sound so odd in North American culture.
