Criss Cross

SPREADING HER WINGS: This morning, we pointed the Honda southbound at 7:30, a bit earlier than usual. However, our destination made it worth navigating through rush hour traffic: The Museum of Flight. Annabelle had a special workshop to attend. I'll let her tell you a bit about it.  
Today I had the honor of going to an event at the Museum of Flight called “Women Fly”. Because I had a reservation, I could go early and watch a presentation from Jessica Cox, the first registered armless pilot. She was born without arms and had to learn all the other things other children in her school were learning on her own, because the teacher didn’t know how she would teach an armless student how to do things like tie their shoes. But Jessica eventually learned to make her laces very loose and then tie them with her toes. She couldn’t put them on and then tie them because that would mean her toes couldn’t be used. She told us to “think outside the shoe” and remember that nothing is impossible. 
She also answered some questions, like if she’s ever had trouble doing things due to an injury. She said yes, one time she sprained her ankle and hyper-extended her knee, leading to her being in a wheelchair for about a month. She got through it with determination, and now she’s done many amazing things without arms, from being a black belt in Tae Kwon Do to being a surfer to being a pilot.
I also went to a few small workshops. The first was about Cassini, a satellite which has been able to orbit Saturn for 12 years. It’s been able to study Saturn this long because instead of using fuel on the trip to Saturn, it used other planets as slingshots to propel Cassini further without using nearly as much fuel. We had a board on the table with magnets in the middle representing Titan, Saturn’s largest moon. My friend and I used metal balls and rolled them towards titan to slingshot towards Saturn’s other moons. It was actually much harder than we imagined, but it was fun nonetheless.
The second workshop I went to was about lightning and static electricity. My group used combs to make static electricity from our hair and pick up small paper bits like confetti.
There were also generators that we had fun “shocking” toy planes with. The event was fun and if you can get reservations next year, you really should!
ADDED BONUS: We weren't quite sure what time Annabelle's workshop would be over, so right after CJ got out of a class at noon, we headed back south to The Museum of Flight to hang out and wait for Annabelle to be done.

I asked CJ what he wanted to see there and he said something he's never seen or done at the museum before. That led to him taking a spin in a flight simulator.

Below, he's doing a little 'pre -flight' training.
He reports the experience was fun, and a little nauseating.

After the 'flight,' I asked him where he wanted to go. He said the World War I and II wing, so there we headed. On the way in to that part of the museum, I noticed a sign.
I looked at my phone, saw it was 1:03 and told CJ to hustle, so we could check out the presentation. I had no idea what we were in for. I'm *so* glad we went!  

I'll have CJ tell you a little bit more about it. ...

Today, my sister spent the morning at the Museum of Flight, a frequent haunt for my family, located down South in Tukwila. She was going for the Women Fly event, which is The Museum of Flight's annual event for youth interested in aviation, aerospace, and STEM futures.
Meanwhile, my mom and I were visiting other parts of the museum. We were visiting the World War branch of the museum, which contains several planes and other relics from both World Wars I and II. On the way in, we noticed a sign, promoting a speech being given by a World War II veteran.
We went to a little "hut" structure in the back of the exhibit to hear the speech. At the hut was Jim Marich, a B-29 flight engineer. was giving a very interesting talk about an experience over and in the Pacific Ocean, that he had back during November 1944's 3rd week (11/12 to 11/18):
In 1944, when Marich was 19 years old, he was the flight engineer on a Boeing B-29 Superfortress, flying over the Pacific Ocean. 
     PHOTO: U.S. Air Force 
The B-29 was flying for a bombing (and, by the sound of it, suicide) mission, and was close to Iwo Jima, a Japanese island. If I remember correctly, Marich was one of 11 crew members on the B-29. The plane's pilot was 25 years old (much older than the rest of the crew), and thus he earned the nickname "Old Man."
At some point during the third week of November 1944, the plane encountered a 200 MPH headwind, blowing against them. Since the B-29 was only going at 230 MPH, this meant that the plane was essentially going at just 30 MPH, and consuming very large amounts of fuel. 
The B-29 and its crew completed their mission (a bombing run), but knew they would not make it back to base. They made preparations for a water landing, throwing things overboard and expending all of the fuel. 
The Pacific water below the plane was mostly going up in swells, primarily around 60 feet tall. The pilot of the plane actually had to try and crash land the plane on one of the swells, an especially risky and abnormal bet. It was assumed that the plane's tail would break as a result of the "landing". After landing the plane in the water using the 60-foot swell, there was a desperate rush to get outside of the plane.
The B-29's crew was told that any plane that hit the water would sink within 90 seconds. The people in the back (6 of them, if I remember correctly) had to quickly crawl through an awkward tube, just to get to the front section of the B-29. Those in the front section of the B-29 (which included Marich) had to crawl through a tiny window on the pilot's side of the plane, just to get out.
After getting out of the plane, life rafts were inflated, and the crew started eyeing which ones they were going to climb into, figuring that's where they would eventually die.
Miraculously, out of seemingly nowhere, a PT Boat appeared, and pulled up next to the plane. Instead of getting in the raft, the crew of the B-29 ended up getting in the PT boat, which included getting wet up to their knees.
Despite thinking that the plane would sink within 90 seconds, according to Marich, the plane didn't sink for more than 48 hours after "landing" on the water.
Shortly before his 20th birthday, Marich would be back at home, in his bed, and the war was over.
Overall, the speech given by Jim Marich was very interesting. Marich also mentioned that there are probably many, many B-29s in Mariana's Trench. I wonder how-well preserved and B-29s in Mariana's Trench would be.
This photo is of *the* very plane Marich was on that was ditched in the Pacific in 1944. He found it by chance, while flipping through a book about B-29s in the gift shop at The Museum of Flight.

We feel fortunate to hear Mr. Marich's story that unfolded 72 years ago. 

I found a couple of interviews with Marich. I'm so glad his experiences are recorded for posterity.

And here is a video of Marich's presentation very similar to what we saw today, in that same little hut in the back of the World War wing of The Museum of Flight.

Super Tuesday

TIRED:  Some not-so-good news from Mars this morning. 

I'll let NASA tell you what's up, per their press release.  
A routine check of the aluminum wheels on NASA’s Curiosity Mars rover has found two small breaks on the rover’s left middle wheel—the latest sign of wear and tear as the rover continues its journey, now approaching the 10-mile (16 kilometer) mark.
The mission's first and second breaks in raised treads, called grousers, appeared in a March 19 image check of the wheels, documenting that these breaks occurred after the last check, on Jan. 27. 
"All six wheels have more than enough working lifespan remaining to get the vehicle to all destinations planned for the mission," said Curiosity Project Manager Jim Erickson at NASA's Jet Propulsion Laboratory, Pasadena, California. "While not unexpected, this damage is the first sign that the left middle wheel is nearing a wheel-wear milestone,"
The monitoring of wheel damage on Curiosity, plus a program of wheel-longevity testing on Earth, was initiated after dents and holes in the wheels were seen to be accumulating faster than anticipated in 2013. Testing showed that at the point when three grousers on a wheel have broken, that wheel has reached about 60 percent of its useful life. Curiosity already has driven well over that fraction of the total distance needed for reaching the key regions of scientific interest on Mars' Mount Sharp.
So, clearly not great news about the wheels' status, and the photos tell the story. In case you're wondering, each of Curiosity's six wheels is about 20 inches (50 centimeters) in diameter and 16 inches (40 centimeters) wide, milled out of solid aluminum. (I can't help but think aluminium is super light for the trip to Mars, but maybe too lightweight for the surface of Mars.)

Curiosity's wheels' treads that hit the surface of Mars are about half as thick as a U.S. dimes. 


As alarming as these photos look to me, NASA scientists seem to be taking it in stride, or tread, as the case may be. ... 
Curiosity Project Scientist Ashwin Vasavada, also at JPL, said, "This is an expected part of the life cycle of the wheels and at this point does not change our current science plans or diminish our chances of studying key transitions in mineralogy higher on Mount Sharp."
Overall, through March 20, 2017, Curiosity has driven 9.9 miles (16.0 kilometers) since the mission's August 2012 landing on Mars. I remember reading about tire worries yeaers ago, and for the past four years, rover drive planners have used enhanced methods of mapping potentially hazardous terrains to reduce the pace of damage from sharp, embedded rocks along the rover's route.

Below is a photo I took of a copy of Curiosity's wheel when I was fortunate enough to attend a Tweetup during Mars Science Laboratory's launch.
As you can see, it's so much bigger and different that the wheels that went before it. (MSL's wheel is far left. It's previous rovers' wheels are left to right.)
TECH TALES: So, a couple of nights ago, along about midnight, we received an email about an opportunity to participate in a group at Pacific Science Center. Honestly, that was all I needed to read before I started furiously typing to sign up, as it was a super small study group, it's a big city and we wanted in!

Fortunately, we were accepted into the study, and tonight was our first get together. For five evenings in upcoming weeks, we'll be working on a pilot program that involves robotics, storytelling and art. What's not to love?!

The program is funded by the National Science Foundation, and it's a collaboration that involves PacSci and the University of Washington. Not a bad pedigree.

Tonight was our first session.
 We got to play around with Scratch programming and a Hummingbird motherboard.
The goal of this project is for us to tell a family story in a diorama using technology/robotics. After our first meeting, we hit upon a theme we all were immediately excited about. 
Stay tuned for further developments. 

SOMETHING FISHY: Today, Annabelle and I headed north and east toward the University of Washington surplus store. There was only one problem: We got there about two hours before it opened. Oops. 

So, we headed back. On our way home, we noticed a bunch of balloons outside the Ivar's restaurant under the Ship Canal Bridge. Annabelle said she saw something about it being Ivar's birthday, and that made me recall I'd read something about that being a big/good deal. I pulled over, Googled it, and we turned around.

Um, yeah, good deal - and worth doubling back for! 

So the kids had an awesome lunch - complete with special mango cheesecake desserts, cause we stumbled upon it so early. 
So, happy birthday to a Northwest icon, and what a nice surprise for us!

Springy

FAIR MINDED: Saturday afternoon, we made our first ever trip to the Bill and Melinda Gates Foundation's Visitors Center. We've walked and driven by it dozens of times. It's just east of the Seattle Center campus. 

Ironically, we didn't really spend but a couple of minutes checking out the many, intriguing permanent displays there. Rather, we were there to check out a special event, the Teen Action Fair.

CJ and Annabelle are both civic-minded and action oriented, and it seemed like a good place for us to go to learn about programs other area teens and pre-teens are involved in.
I'll let CJ take over narration for a bit ...  
Since 2014, the Bill and Melinda Gates Foundation has been host to the Teen Action Fair, which, according to the South Lake Union Chamber, is an annual youth-led event showcasing young leaders (primarily in their teens) who are inspiring positive change. This year's Teen Action Fair included over 30 diverse youth-based organizations as part of their program, with several of them setting up info stands to learn about the organizations.
One example of a group I learned about at the Teen Action Fair was Junior Asha. According to a handout at the TAF, Junior Asha is the youth chapter of Asha Seattle (a nonprofit organization that helps the underprivileged in India, mainly through education). Junior Asha "encourages youth participation in the community", and everybody aged from 12-18 can join Junior Asha.
Another group I learned about at the TAF was Birthday Dreams. According to their official website, Birthday Dreams is a non-profit organization dedicated to bringing joy to homeless children with the gift of a birthday party. Birthday Dreams serves the Puget Sound area, and we were actually able to do a little service for Birthday Dreams at the TAF, by filling gift bags for the homeless kids with toys and candy.

The Teen Action Fair was a very informative and interesting event, and I would like to go again.
SOURCES:
There was a lot of diversity among the groups, and so many really wonderful projects and programs, it made us want to volunteer for all of them!

At the booth below, the kids decorated book bags that were bound school kids in Kenya.
We each filled out cards listing causes we support locally.

We only took a quick look at the regular exhibits at the center. We definitely need to go back in the near future!

POPPIN': Monday afternoon, we took a field trip to the South Park neighborhood in South Seattle for the opportunity to tour a successful local popcorn company that is getting notice far and wide.

Before we could go in the production facility, we had to don hairnets.

I'll let Annabelle tell you a little bit more about the visit.
Today I took a field trip to Seattle Popcorn Company, the producers of Uncle Woody’s caramel corn. The production facility was very small and there were only about 5 employees working at the time (our tour guide, the CEO of the company, said that a few employees were out sick).

CEO Jesse Greene showed us how they pop their popcorn with only the essentials- corn, salt, and soy. He said they use soy instead of butter because it’s better for you and it’s organic, something they pride themselves on. Right next to where the popcorn was popping, an employee was dumping popcorn into their real butterscotch mixture, which is made with organic cane sugar. 
He then led us over to a bagging machine, which had one error as we looked at it (one bag didn’t get sealed), but our tour guide used this bag to show us how their metal detector works. The metal detector isn’t legally required, but if a nut or a bolt fell off the machinery and into the popcorn mix, the detector would sense the metal and push the bag off the conveyor belt.
He then took us to the cool room, which has the ingredients for making heat-sensitive flavors like cheddar and truffle salt. We bought a bag of truffle salt, and it was very good! He explained that the truffle salt flavor is more expensive because they use real truffles instead of flavoring like other companies. Other companies use flavoring because European white truffles can cost as much as $3,600 a pound! However, it does taste better with real truffles. At the end of the tour, everyone got a complimentary bag of caramel corn on our way out. The tour was really interesting and I learned a lot about their process of making popcorn!
One of the most interesting things I learned is that 'mushroom' or globule-shaped popcorn is used for making caramel corn, while 'butterfly' popcorn (more spread out) is used for the flavors that aren't so heavily coated.
The CEO of the company was super enthusiastic. The company is small, just 10 employees, but they ship their product worldwide. Greene recently took a trip to South Korea with Washington Governor Jay Inslee as part of a small business junket. 

GREEN SEEN: I didn't manage to get a post up on Friday night, but suffice it to say, we celebrated St. Paddy's day with a little fun, including green oatmeal for breakfast. 
The kids were amused, and found it more appetizing than the green eggs we had on Dr. Seuss' birthday on March 2.

And before we sign off for the night, we have to give a nod to spring, which has arrived on the scene. It was a long, cold winter in Seattle. Here's hoping spring is sunny and mild!

Ray of Hope

FINALLY, SOME SUN: We walked around half blind today. Blinded by the light, that is. As in full on sunlight. As in something we haven't had hardly any of since October 1.

We awoke to blue skies, and there was instantly a little extra spring in our steps. So we took some extra steps. Annabelle enjoyed 1.5 hours of a Girls on the Run club she recently joined, and CJ and I took a stroll around the Seattle Pacific University campus. We've driven by and through that campus hundreds of times over the last 10 years, as it's right by our house. But until today, we'd never walked it, if you can believe that. 

We started at this archway. 
Today, we learned it leads to the Tiffany Loop.
We also learned what year SPU was founded. It's carved into one of the bases of the arch.
As we walked around, we came across a story pole we'd only see as part of the 'nearby' map while playing Pokemon Go.
Naturally, we took the time to read the story about the story pole.
We also took the time to size up this enormous tree in the middle of the Tiffany Loop.
And we came across this nifty bike maintenance station. It had a pump next to it and tools hanging from it. What a good idea.
All in all, a pretty little campus, with nothing but brick buildings. We'll definitely stroll through there again some day.

WILD FOR FLOWERS: Yesterday, something about bees, Cheerios, wildflowers and free seeds kept popping up on my Facebook feed. Naturally, we had to check it out.

Turns out Cheerios, in partnership with Vesey's, had pledged to give away 100 million (!) wildflower seeds in a campaign to help #BringBacktheBees.

Why bother? Well, according to the Cheerios site, 1 in 3 bites of food we eat is made possible by bees and other pollinators, and 42% of bee colonies in the U.S. collapsed in 2015.
When I hopped on their site (http://www.cheerios.com/bringbackthebees) yesterday, the meter said they'd already reached their 100 million goal, but it let me enter my data anyway and said some seeds were headed our way.

This evening when I checked again, things were a bit different. ... 
So the bad news is, no more free seeds. The good news is, they are giving away 1.5 BILLION seeds. That's so cool. We can't wait to receive ours! 

They also posted a map of where the seeds are being shipped.

MUD-DAY: I never did post about our Monday. It involved heavy duty physical labor. For six hours. In the frequently pouring rain. 

Demolition, digging, dump runs, all sorts of fun. We were working on improving a school garden alongside a service group of teens and young adults from Oklahoma, believe it or not. There were probably 22 or so of us in all. While it's true many hands make light work, there was major work to be done, so it didn't feel all that light!
We had the added bonus of having a dead battery during the dump run. Good, good times. 

INSPIRING: As part of the social studies club they belong to, the kids are producing profiles of people they admire. Here's CJ's choice ... 

Faster-Than-Light: Meet Miguel Alcubierre

Have you ever dreamed of travelling faster-than-light to other planets, star systems, or even galaxies? Unfortunately, our current space propulsion systems would take far too long to get to far-off places in space. However, one man has a possible solution: Dr. Miguel Alcubierre Moya (better known as Miguel Alcubierre), Director of the Nuclear Sciences Institute at UNAM, is a Mexican theoretical physicist.
Miguel Alcubierre is best known for proposing the Alcubierre Drive in 1994, a theoretical propulsion system that would allow spacecraft to travel faster-than-light.

Miguel Alcubierre was born on 28 March 1964, in Mexico City. In 1988 and 1990, Alcubierre received degrees from the National Autonomous University of Mexico, after which he traveled to Cardiff University, in Wales to attend graduate school. In 1994, Miguel Alcubierre received his Ph.D from Cardiff, through study of numerical general relativity.

Later that year, Dr. Alcubierre wrote “The Warp Drive: Hyper-fast travel within general relativity,” the original article in which he proposed the Alcubierre Drive. The Warp Drive was published in science journal Classical and Quantum Gravity.

In The Warp Drive, Dr. Alcubierre describes the Alcubierre Drive as being a system in which the space in front of a spacecraft is compressed, and the space behind the spacecraft is expanded. The Alcubierre Drive would theoretically let a spacecraft travel at faster-than-light speeds.
In 2012, Dr. Alcubierre was appointed as the Director of the Nuclear Sciences Institute at the National Autonomous University of Mexico (UNAM). In 2016, Dr. Alcubierre was reappointed.

Pi, Pie, Pi, Pie!

PI-PALOOZA: It's Pi Day, that super special day of the year where you eat nothing but pie for a whole day, at least if you are hanging out with Magnolia Preparatory Academy folks.

Pi day, is, of course, really all about that beloved irrational number, an infinite decimal that starts with 3.14, hence Pi Day being March 14. 

The kids started their day off 'right' with apple pie for breakfast. We did not bake it, we scored it on sale for just $1.50 from a local grocery store. 
Lunch was pizza pie, which they shared during their Dungeons and Dragons club meeting today at noon. 
Dinner was a bit of a project. We made two gluten-free chicken pot pies. 

Making pot pie is a lot of work. We had to cube and cook chicken. We had to make chicken broth. We had to cut up onions and brown them. We had to peel, dice and boil potatoes. 
We had to get carrots, peas and green beans ready. We had to combine it all with some milk and cornstarch to make the filling.

Making the gluten free pie crust was the real challenge. I'm not great at pie crusts to begin with, Turns out that's also true of the offspring helping today. ...

CJ cracked eggs under the watchful eye of birthday boy Albert Einstein.
 We cut in butter and made disks of dough.
 Rolling out the first pair of crusts went well enough. 
Unfortunately, the second pair was pretty much a disaster, as someone blew right by the part of the instructions that say to add water one tablespoon at a time to the flour, salt, butter mix. The dough was waaaay too sticky. More than adding a bunch more flour could really fix. 

We par baked the bottom shells and filled them, adding a few crunchy onions for fun before topping them with our sloppy pie crust. 
The photos at the top of the post were of our pasty looking pre-baked pie. I guess I forgot to take photos of it fresh from the oven.

While it was a lot of work and the pie crust got the best of us, it was worth it, I guess. The pie was delicious. 

Tomorrow, we'll actually do some non-cooking related math. And eat healthier. :)

FLASHBACK: Thought I'd take this opportunity, Einstein's birthday, to share a favorite project from the past. CJ wrote this poem about Einstein as part of an Einsteinian physics class we took back in 2013.
