One Cool Hotspot

Okay, wanna see something really cool? (Actually, it’s kinda hot …)

Below is a cropped image from a 1969 National Geographic map of the seafloor, showing the Pacific basin. What’s the cool part? See that long, almost L-shaped line of ridges and seamounts and islands that has Hawaii at the very end? That’s where the Pacific Plate has slowly moved over a hotspot in the earth’s mantle, which causes seamounts to form, and, occasionally, islands like Midway or Hawaii.

Pacific Floor Ocean Map, National Geographic, 1969.

The ridges show the movement of the Pacific plate over the last 75,000,000 years. Kind of slow movement, only about 6,000 km in that time, or 0.000000009132 km/h, about 80 mm/year.

That bend in the L is where the Pacific plate shifted direction 43,000,000 years ago.

In case you’re wondering where it goes as it moves, you can see the trenches on the top and left edges of the plate. Those are subduction zones, including the Marianas Trench, the deepest part of the ocean on earth. That’s where the Pacific plate is moving underneath the other plates, getting recycled very, very slowly.


Notes:

Ciphers in the Bible

Found an interesting tidbit in a children’s book I have: The First Book of Codes and Ciphers by Sam and Beryl Epstein.

The First Book of Codes and Ciphers
The First Book of Codes and Ciphers, Sam and Beryl Epstein

And all the kings of the north, far and near, one with another, and all the kingdoms of the world, which are upon the face of the earth: and the king of Sheshach shall drink after them. (Jeremiah 25:26)

SHESHACH in Jeremiah 25:26, and elsewhere, is a Hebrew backward alphabet cipher called ATHBASH (the English equivalent of which would be AZBY, although we would transliterate it as ATBASH). SHESHACH means BABYLON (or BABEL).

The same type of cipher is used in Jeremiah 51:1 and 51:41.

See https://en.wikipedia.org/wiki/Atbash.

90 Years in 900-ish Words

This is the summary of my mother’s life that I presented at her funeral.

(Okay, 1,027 words …)

I want to tell you a little bit about our mother.

Our mom, Rachel Adeline Sampson Wilcox Fortini (not her real name, which was Rachel Adeline Wilcox pretty much forever) was born a long time ago. She saw more than a few things in her life: The Great Hurricane of 1938, World War II, the invention and use of the atom bomb, jet travel, the Civil Rights movement, the moon landings (indeed, the entire space program), and the Internet. It won’t be easy to summarize her life in a few words, but there are some themes that stand out.

Mom grew up on a small farm in Freetown, Massachusetts, purchased by her father after a whaling voyage out of New Bedford on the bark Sunbeam. She moved to a tiny house on the same property after she got married, a house that would rapidly become far too small.

There are those who merely repeat the errors of their parents to Family Law Firm. Mom was the opposite. She had a strict policy of laissez faire for her adult children. If we wanted advice, almost always, we would need to ask for it. Cutting the umbilical was never a problem. In fact, my parents moved to Florida the same week I left for college, and they never gave me their new address. (I’m sure it was accidental.)

Mom seemed eternally young. She survived two husbands: My father, Paul Wilcox, and George Fortini, whom Mom married when she merely 80 years old. (This never fails to evoke a huge smile when I tell people.) My children, until a few weeks ago when it stopped being funny, insisted that Grandma would outlive us all. And, she will, having preceded us to Eternal Life.

I often think of Mom’s incredible practicality. In a time when women didn’t have bank accounts, it was my mother who always managed our finances, because she was a trained bookkeeper, and Dad wasn’t very good at it. She shoveled snow, painted the house, fixed things.

She was willing to defy social conventions in other ways: I am, like Paul John and Aaron, an adoptee. I never remember learning I was adopted; I do remember discussing it with Mom when I was young, but clearly learned about my own adoption at a very young age. She even made it clear that she would support me or help me in any way, if I wanted to contact my biological parents.

Mom and Dad, long ago.
Mom and Dad, long ago.

In the early days of the Cold War, my sisters remember Mom’s reaction to heading down into the basement in Easton, Massachusetts, evaluating it as a fallout shelter. Mom declared, “This isn’t going to protect us at all.” Scary, perhaps, but correct.

More importantly, we never learned prejudice in any form. Even in New England, this was unusual.

Although Fran often gets the credit, Cindy claims to be the one to first encounter saving faith in Jesus Christ—but, it seems she was merely the first to be vocal about it. Joyce remembers trusting Christ, albeit without much publication, even earlier than Cindy did. Fran followed soon after Cindy, but it was probably Cindy who was first actively praying for her family. (Cindy suggests that following Christ was an act of rebellion.)

Mom embraced Christ fully. Cindy remembers an immediate reduction in worry and even a slight reduction in the fanaticism of cleaning. (Mom used to lock the girls outside so she could clean.) That faith was evident her entire life. I got chewed out only a few weeks ago for taking too long to return one evening, because she wanted someone to pray with her, although she did nearly all the praying.

Indeed, she was, “a light of Christian faith, shining in a dark world.”

But our mother was, most of all, a Mom. All caps. One hundred percent. She elevated what is a noble duty and profession to a veritable ministry.

Mom had more than few children. Four inferior biological ones, all girls. Fran, Cindy, Joyce, Martha. (Or, as Mom spoke, Mah-thuh.) When those started to become less fun and move away, she began the 15-year process of adopting three boys. Myself, Paul John, the brother I prayed for for years, and finally, Aaron.

Mom was an excellent parent. Strict but never, ever unfair. (Except when I, at a young age, called her a liar because she, for the first time ever, accused me of something I hadn’t done.) My perspective may be a little skewed, because, as my sisters point out, I had older parents, who had been well broken in by the time I came around. Judging from some stories I’ve heard this week, this is almost certainly an accurate interpretation.

When, at 2 or 3, I needed to be instructed in the art of, “Don’t get too close to the street,” Mom painted a line on a rock at the edge of the driveway, and said, “Don’t go past that line.” When I broke a treasured piggy bank at age 4, she explained that she would fix it this time, but if I left it on the edge of the bed again, and it broke, it would be destined for the rubbish bin. I did, and it did. I was sad, but she was true to her word, and eminently just.

She would often explain how things worked. I remember seeing the Apollo 15 or 16 launch on TV, and having her explain that the Saturn V was bringing people to the moon.

And, Mom loved babies. She did foster care for, we think, 57 of them. She retired from foster care, later in her life, at least four times. My friend Tim called them “trade-ins.” One time, while returning a trade-in back to Boston, she was in tears. A young Paul John patted her on the arm and said, “Don’t worry, we’ll get you another one.”

Mom was very humble about this, indeed about everything. “I didn’t want it to seem like I was trying to do some big thing … I didn’t want the Lord to think that I was bragging.” Even days before her death, she was fretful that she hadn’t done a good enough job. I suppose all mothers suffer this unending guilt, and she had so many children who called her Mother.

We were so very blessed to be entrusted to her.

Living to Die

It is the 5th of July. Despite only a 3-hour flight, I’ve devoted most of the day to travel. Finally, after almost 12 hours of driving/waiting/flying/waiting/driving, I make it to Hospice House. Surprisingly, this is my first time visiting a hospice location. Although hospice was very helpful with my father’s last weeks, that situation was very different.

He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away. (Revelation 21:4, ESV)

Main sign for Hospice House

The lobby is beautiful. With fireplaces and chairs, it reminds me more of a relaxed hotel than a hospital setting. There is a tiny chapel off to one side, and a beautiful stone list of donors, decorated splendidly with a carving of a great blue heron in flight. But, I barely notice it.

I make my way, of course, to the wrong end of the hall. It is relatively late, although not at all dark, yet, and very quiet. When I get to the other end, I quietly inquire for my mother’s room number, describing the various ways she might be named. Addie Wilcox? Rachel Wilcox? Wilcox-Fortini? Mom’s legal name is Rachel Adeline Wilcox, but she never liked her first name, so she was Addie to nearly everyone.

Room 12. Give us a few minutes, we’re getting her cleaned up. So, I wait a few minutes for the nurses to finish. Finally, I get to see Mom.

“Oh!” she greets strongly, “My ugly son!”

“Ugly?” I exclaim in disbelief, “Compared to Paul or Aaron? I don’t think so!”

I last saw Mom in October, when Sarah and I had a long-weekend visit because, as Sarah insisted, “Your mother is not going to be alive forever. We should see her while she is well.”

A motley crew at Charlie’s Fish House, October 2016. Yes, that is how my mother smiles, a genetic gift from her own father.

Now, not much later, Mom is markedly older. She looks tired. She is painfully thin, massing definitely under 45 kg. Her speech is slow, but clear. I also discover she can’t hear me unless I speak very loudly. She’s good at covering this, but her responses to questions she pretends to hear are often non sequiturs. (Later in my stay I will tackle this problem and diagnose a bad hearing aid, and come up with a good-enough-for-this-lifetime solution.) However, she is “all there.” Her mind and memory are, for the most part, intact. This is something of a disappointment to me, as I was hoping to be able to re-frame a few minor incidents from my childhood. This won’t be the case.

I know, given the hour, that Mom will be tired, soon, so this visit will be short. There is one complaint Mom mentions at least once a day, and today is no exception: “I don’t know why the Lord still has me here, but He must have some purpose. I just wish I knew what it was.”

I understand her impatience to meet the Savior. She knows the time is soon. She is nearly 91. In less than a year, she has gone from driving interstate, living alone in her own home, and being in near perfect health, to having trouble walking, needing in-home care, and frequently visiting the hospital. The past two months have been particularly difficult.

My children often claim that Grandma will outlive them. This joke, which we have enjoyed for years, doesn’t seem as funny this week. I can’t keep a few lines from a song in The Muppets Take Manhattan, out of my head: “Saying goodbye, why is it sad? / Makes us remember the good times we’ve had.” The brain does strange things at times, as I will discover tomorrow.

I don’t know, of course, if this will be my last visit with this woman of many children: Four biological, three adopted, 87 (we think) fostered. I wonder if, sometime between my leaving this night and returning in the morning, my mother will go from seeing the object of her faith “in a mirror, dimly,” to “face to face.”

All too soon, Mom slips into a quiet sleep, and I drive the rest of the way to her house, navigating through tears, to where my sister Cindy is “holding down the fort,” as Mom would say.

Yes, we are of good courage, and we would rather be away from the body and at home with the Lord. (2 Corinthians 5:8, ESV)

A Teacher Worthy of Notice

(A reflection from November 9, 2016)

While my wife—Sarah Latimer—and I were walking our dog, Juno, we chanced upon an outside window of this history classroom at Nashua’s Fairgrounds Middle School, where our daughter, Naomi, attends.

I was moved to tears at the display, particularly given the anniversary of Kristallnacht. This was a meaningful reminder that, despite what we have seen all too often on social media and propaganda outlets, there are, indeed, those like this English teacher who are quietly and efficiently going about making the world a better place for all our children.

The Signs of Science

One of the best parts of the March for Science Sarah and I attended on April 22, 2017, in Washington, D.C., was the nearly endless creativity the marchers put into their signs. Not too many were repeated, and few would have been considered offensive. The preview image here is my sign, cribbed from “Stand back! I’m going to try science!” of XKCD origin.

All the signs we photographed:

TramBot (Originally published in 1998 or 1999)

The TramBot—When my nephew Dave Matheson (a veterinary grad student at Prince Edward Island) stopped in for a day-long visit, we constructed a TramBot that ran on a string stretched across an upstairs room with a light-activated set of “grabs”—perfect for bombing runs. This was inspired by the “Bomber Fly” seen in assorted Lego media.

Yes, I Always Over-Design

If you’ve seen the Bomber Fly in the Lego publications, then you will immediately notice that my creation is much bigger, and probably heavier. I developed a fear of minimalism after my very first RIS creation quite literally shook itself to pieces in under 10 seconds.

Features and Innovation Details

  • The forward-reverse pulleys are driven by a belt drive, although a geared drive would have been fine in this case.
  • There are bumpers connected to touch sensors on each end that reverse the drive pulley motor when triggered. Because the string is at about a 45º angle to the wall, we added the tires to keep the bumper rods from slipping. (Before this was done, the bumpers would sometimes just glance off the wall without triggering the touch sensors, as the robot tried to keep moving.)
  • We solved the problem of timing on the “grabs” (the name alludes to Gerry Anderson’s Supermarionation Thunderbirds program—see https://www.gis.net/~fm/) by using a belt drive, and setting the motor run time to one second longer than the absolute maximum necessary. This allowed the grabs to automatically re-synchronize, be movable by hand, and grip objects of various sizes.
  • The grabs are light-triggered. We used the Lego light sensor, and programmed it so that a flashlight beamed on it would trigger the grabs’ open or close sequence. This allowed for precise payload delivery.

 


My sons Isaac and John, my Nephew Dave, and I perform some final adjustments and testing.

To Boldly Go …

3-Year-Old Builds Lego MindStorms Robot

Isaac’s First Robot—The “Punching Robot”

(Original date, approximately 1998.)

Hey, He Was Only 3

At three years old, my son Isaac might have been the youngest person ever to construct a Lego MindStorms project. Although he calls it a robot, it is more of a contraption than a real robot … but I cannot help but be impressed.

Isaac built this entirely without help—he even connected the RCX to the motor properly on his own. The design is entirely his; I never built anything similar.

Isaac grins as he contemplates his world conquest.

This contraption, which he calls a “punching robot,” uses an assortment of Lego axles that rest within a 40t gear, that is directly mounted on the motor. Attached to several of the outer axles are the shock absorber pieces. These shock absorber pieces extend outward from the central gear when the motor is activated, and will repeatedly punch whatever the robot is placed near.
