Day Zero: Get Thee To Flagstaff

There is no simple way to orchestrate the travel here.  Yes, planes fly to Flagstaff, not the same airlines as fly to the big airports but their small-scale partners.  There’s a shuttle bus from Phoenix, and if you were facing a long layover the van could even be faster.

But we arrive in Phoenix with plane tickets in hand and actually welcome a half-hour flight delay, because it allows us a chance to buy lunch.  I even have time for a stroll through the overpriced-souvenir shop, where I hand over $2 for a pair of elastic bands someone in the shop has put out to support a fundraiser for improving water supplies in Haiti.  Seems appropriate. And the chance to put up our feet for a half-hour is welcome, as we’re already tired.  We actually began yesterday, on Day “-1”, with a five-hour drive to rendezvous with Clark’s friend, who lives near Reno, so we could all travel together the whole way.  Our Day Zero expedition consisted of a drive from the pine forests of Plumas County to the desert flats of Reno’s outskirts, a freeway jaunt to the airport (chauffered by another friend), a big plane to Phoenix, a little plane to Flagstaff, then a search for the airport shuttle.  We will have a powerful case of deja vu on Day Fourteen.   You’ll see.

Flagstaff’s airport is a fabulous, small airport.  My favorite kind.  One baggage claim zone.  No trouble meeting a shuttle bus right outside.  As it happens, the other folks sharing the van are another couple going on our trip.  And they have obtained an intelligence report from the rafting company, OARS, that we five will be the only “guests” staying on the raft trip for the full fourteen days.   The rest of the group will leave halfway (and hike out), to be replaced by a new batch of folks for the second week.  So we will actually get to spend a full fifteen days with Todd and Eliza.  Oh, yeah, and until such time as the members of our trip group authorize me to use their names, I will be using fake names, just in case I goof up and say something upsetting or someone turns out to be in Witness Protection.  I won’t do the same for the crew, since I want to actually give them the props they deserve.  In fact, I’d hope this whole piece could be considered a humungous letter of reference for each and every person on the crew.  I’d initially given myself permission to use my own and my husband’s names, but he protested, so here goes.  He is herewith dubbed “Clark”.  And what to call Childhood Friend?  How about Lana?  And surely that makes me “Lois”.  The only funny thing about this, is that I actually have a friend called Lois–so, hey, Lois, you can tell people this is you.  (Fair warning, though, I’m not the heroine of this story!)

The key element of Day Zero is the evening briefing from the Trip Leader.  We gather in one of the Radisson Hotel’s conference rooms.   (The Midway guests also will have a briefing, but not by the Trip Leader , as she will be a mile downhill at the time.)  So we meet our first authentic River Guide.  This is Billie Prosser, who’s been whitewater rafting since she was a teenager, over fifteen years now, much of that time in the Grand Canyon.  These days, she chooses to do only a few of these Grand Canyon trips a year, giving herself the chance to work on other rivers and also to have time for a private trip, as time permits, to enjoy the Canyon without having to take care of people like us.

At the meeting, we also get our first glimpse of our fellow travelers all together.  We are heavily loaded with Californians and Canadians.   There are three women from Canada—their menfolk didn’t want to come.  There’s two father-son duos: one a dad and his athletic teenager, the other a Bechtel project technician taking a voluntary layoff to make the trip with his dad, a (putatively) retired actor and writer.  The Fab Five (Todd & Eliza and the three of us–Lois, Clark, and Lana) are all from California.   The actor, who takes care during the meeting to firmly establish that he’s the most-senior member of the troupe, has also brought along a childhood friend—a woman he hadn’t seen since high school.  While he keeps us entertained, I get the vague feeling he sort of expects someone to recognize him.  Then there’s another triad…a husband and wife and one of their friends.  Is that sixteen?

We get a quick summary of what to expect in the morning.  The crucial item is to have our gear packed and in the lobby by quarter to seven and be ready to leave by seven.  There’s a little last-minute advice on what to be sure to bring.  In case something’s been forgotten, there’s a WalMart in walking distance.  We’re advised to bring lots and lots of moisturizer.  I ask for a definition of “lots”, which it seems is a 16 oz bottle per person per week.  Oh, my goodness, I didn’t bring that much, so we have a trip to WalMart in the plans already.  We’re issued our “drybags”, each labeled with our own personal real names.  (Amazingly, they don’t know to use the fake names I will make up in the future for this blog.)  And Billie gives us a five-minute seminar on how to seal the drybags.  This is important, as all of our clothing and personal items go in this bag, which will then be tied onto a raft and frequently doused with water.  We’re each also issued a small drybag.  The big bag is inaccessible except in camp.  The day bag serves to keep dry what we need to keep dry but have access to during the day.  And we’re allowed to bring whatever we like in our daypacks as well, provided we understand that these will get drenched in larger rapids or if it rains.  The drybags don’t have our personal names on them.  Instead, they each have an identifying name written in Sharpie,  to individualize them.  We just each have to remember our bag’s name.  Mine is “Turpentine Broom”.  Lana’s is “Grease Bush”.  And Clark selects the distinctly memorable “#73”.  Mine is the best.  Here is all about Turpentine Broom  and Grease Bush.  I expect we’ll encounter these plants on our journey.  In the meantime, the names help, as the bags come in only a few colors.

I’m relieved to hear there will be a bag for boots, as this will make room in my kit for all that moisturizer.  Others are relieved to hear that their beer and wine orders have been filled.  Some are anxious to double-check on that after the meeting.  Billie has the checklist.  Evidently, this is a common anxiety.

Then we are off to WalMart.  Yes, our first act upon crossing the moment into our trip environment is to walk down a suburban city street, past a dark and quiet Home Depot, an active supermarket, and a Bank of America with lights glowing invitingly above its ATM, to shop in the megabehemoth of a store that was launched just a few miles from Clark and Lana’s home town.   But oh, they do indeed have It All.  More sunblock.  I must have more sunblock.  Moisturizer, per Billie’s recommendations.  Handy dry facewash cloths to get all that sunblock off.  And a tripod.  What was I thinking, leaving home without a tripod?  And a little mini flex-tripod for Clark.  Sweet.  Now all we have to do is haul this all back to the hotel and get everything crammed into our bags.

And, well, the bag-cramming takes a little while.  Maybe more than a little while.   Part of it is deciding which things are OK in the backpack (maybe in a Ziploc bag, maybe not), which need to go in the daybag, and which can be done without and stuffed in the main drybag.  I have the extra variant that I really have 2 daypacks. One is a one-shoulder sling pack that keeps my cameras and other hiking essentials from bearing down on my healing shoulder and when not in use tucks into the main pocket of my large daypack.  The main daypack takes my raingear, a dry set of fleece sealed in ziplocs, my tripod, and other handy items.  It’s big, it’s bulky, I will make Clark carry it as much as possible.  But it all fits.  And while I fancy myself adept at this sort of thing, it is Clark who is already proving to be better at sealing the big drybag.  He says it is just that he can squish it down better, being a bit heavier, but I think there is more to it than that.  I will keep insisting on doing my bag myself for about four more days.  Then I will give up and let him do it for me.

One last shower and a thorough hair washing.  It will be 2 weeks without a shampooing, at least for me.  I do not want to look at the setting on the alarm clock.  It is just too awful to contemplate.

Gravity & EnergyGravity & Energy

This category of the blog is dedicated to science & technology topics that I think may interest my fellow nerds.

(Note: Original post: 2012. A few updates were made during site reorganization in January, 2021.)

Tracking Movement In the Solar System

For starters, I’ll be posting in the blog regularly under Astronomy & Astrophysics. (In some of these older posts the category is tagged Pixel Gravity.)  To jump straight to those posts, visit the PG Archive–readily accessible in the menu.  For some time now, I’ve been running the social-media support for the program that made the picture you see here.  I’ve been posting about robots, space exploration, astronomy, big steps in physics, and so on.  Sometimes, the space available for a posting on Facebook is too restrictive.   So those kinds of discussions will move here.

What qualifies me to write about this stuff?  Well, I’ve admitted elsewhere that we are a family of hypernerds.  That’s not my term.  It was invented and applied by one of our charming (adult) offspring.  It’s not a misnomer As a family, we are 40% engineers and 60% scientists.

I’m a power systems engineer, which in my case means I’ve made a career out of simulating how power plants and electric and gas networks operate.

My husband is a computational physicist, specializing in solar physics.  Want to know what’s going on inside the sun?  He’s your guy.

Our youngest son is too busy for now, building catapults and robots on his way to a mechanical-engineering degree at UC Santa Barbara. (Update: graduated, with honors. Currently open to job offers.)

After two summer internships in NASA’s astrobiology group, our middle son is working on an honors thesis project on metabolic processes of microbes in deep serpentine wells, attracted by the prospect of doing biology fieldwork in extreme ecosystems right here on planet Earth. (Update: he’s now nearly done with his Ph.D.)

And the oldest escaped from UC Berkeley’s astrophysics program with a degree and a desire to never return to academia.  He built Pixel Gravity instead.

What’s “Pixel Gravity“?  It’s a detailed, graphical astrophysics simulator with real-time controls.  It looks sort of like a game, and it’s fun to play with, but it’s also a serious science tool  As an “n‑body” simulator, it lets users model complex groups of many objects, from the solar system to galaxies.  Most of the other easy-to-use programs available online limit the number of objects or lack physical accuracy, so (for example) relativistic effects on motion near a black hole are not handled properly, if at all.  University researchers have access to extremely-detailed models, but those require supercomputers.  Pixel Gravity provides accurate modeling on personal computers and is priced low so that even students can explore gravity in action.  In addition to Newtonian gravity, Pixel Gravity models the additional effects of atmospheric drag, general relativity, and dark-matter, as well as user-defined forces.  Plus, the software package includes helpful tools for curriculum development such as a tutorial-builder and video-production capability. (Update: Pixel Gravity is at present a retired product–contact us if you’d like a copy to play with.)

So, in short, the topics under this heading are just the kind of things we talk about at our house.  So if you come to dinner, you don’t need to bring a foodie specialty.  But you might scan the latest issue of Scientific American.

Rediscovering Old BooksRediscovering Old Books

I spent my elementary-school years soaking up the very best in English literature.

For a preteen horse-mad bookworm that meant: Enid Blyton, Hilda Boden, Josephine Pullein-Thompson, her sister Christine Pullein-Thompson, and Many More. I didn’t notice at the time, but now it’s obvious:  all my early writing models were women. My very first book purchase was a pony book by Hilda Boden, who took up writing stories to help support her family. I kept that book–Joanna’s Special Pony–for years, and reread it many times, imagining the windswept Scottish coast populated with wild (but tameable) ponies and admiring the resourceful, determined heroine of the tale.

I’d nearly forgotten Lilian Buchanan’s illustrations–until I saw them again, and recognized them.

From that day onward, every smidge of my allowance (well, sparing a few pennies for sweets) went for the next installment of the Famous Five or Malory Towers or any number of pony books.

All of those books stayed behind in Yorkshire when my mother had to pack us all up for the move to the States. My British childhood was over, and military moving allowances are based on weight, so . . . my pony books, boarding-school novels, and mysteries went to the thrift store for some other child to collect.

“I thought you were done with baby dolls, you still have the Barbies,” my mother argued.

“Not all of them,” I countered. “I promised that one, the littlest one, that I wouldn’t ever ever give her away.”

But it was too late. 

I think maybe I broke my mom’s heart a little bit. Well, a little bit more. Motherhood involves a lot of heartache. Well, Baby Doll may have been lost to me forever, but I’m sure she had at least one more little girl make her similar promises.

The only good thing about the move was that all my friends had to study up for the Eleven-Plus, which would determine whether they’d go to a nice boarding/academic secondary school (like Malory Towers), get stuck in a dead-end “modern school” with no college track, or take up a trade and actually be able to earn a living. Me, I got to spend a couple of weeks coasting through the end of what Americans called “fifth grade” sitting in a classroom with children who–it seemed to me–hardly read at all, before being unleashed to a long, long American summer vacation. Luckily, my grandparents’ house was packed with books–mostly Reader’s Digest collections, but also a classic edition of One Thousand and One Nights and my dad’s stash of science fiction magazines.

Over the years, those old-style children’s books have been supplanted in the market by more literary-style books for children, others with science-fiction or fantasy roots, and thankfully many with more diverse casts of characters. A few have received a dusting-off over the years . . . there’s even a 2020 BBC-TV adaptation of Malory Towers that puts the storyline in a historical-fiction context while also envisioning a more diverse enrollment and faculty at the school.

Now, it’s my turn to have a house packed with books, and it’s an eclectic collection–not even taking into account all the books that aren’t technically mine, but my husband’s.  No matter–I put them on the shelf and dust them (occasionally), so they’re mine in that sense. I’ve launched a little Instagram project to share a few of those books, on a regular basis–mostly the out-of-print ones, the ones I inherited from my Dad (a fellow SF fan), and ones that may be old but that still speak to current issues.  The hard part is figuring out how to photograph them–top bookish instagrammers have such lovely still-life setups for their book posts. I’ll do my best to at least not to give people eyestrain.

None of that means I’ve stopped gathering-in books. Just in time for my birthday, my very first Quarantine Birthday, I retrieved a book long-lost in the move from England, my first book purchase, my favorite book from that day until the day it vanished to the thrift store with my dolls. 

The dolls are gone, my mother long forgiven, but the books never have left my mind. Just this month, I made a birthday present for myself of a copy of Joanna’s Special Pony, dusted off from some other collector’s shelf–one in better condition than the one I left behind, PLUS a copy of the sequel. That was a book I never got my hands on, because it was only in hardcover and my allowance was two shillings sixpence, exactly the price of a paperback (my, what a coincidence–almost as if my parents wanted me to buy books).

If you like Instagram, the series is here. I’ll try to remember to link to those postings from the Facebook page as well.

Walking to Pluto: Step 2Walking to Pluto: Step 2

Step 2: The List of Requirements:

Don’t worry.  This is one of the least expensive major science projects you’ll put together.

You’ll need:

Note that

I found a sunny yellow ball for my Sun.

1) Any ball roughly 8” (19mm) in diameter—a basic playground ball is likely to work, as will a standard soccer ball. FIFA size 5 works for the English-units model; the SI model is slightly smaller, so a youth-sized FIFA size 4 is appropriate—but don’t get bogged down in the details. Visually, when compared with the planet models, all of these ball sizes look the same.  It’s most likely that you already own or can borrow a ball for this project; if you simply must buy a ball, you should be able to find one for under $10.

 

 

2)  A set of eleven objects to represent each of the eight planets, our Moon, and two of the dwarf planets:

Mars or Venus

Mars or Venus

Pluto or Ceres

Pluto or Ceres

a)  four pins (two pin heads represent Mars and Venus, two pin points represent Ceres and Pluto),

The Moon Is Made Of Green Candy

The Moon Is Made Of Green Candy

b) one tiny candy nonpareil (cake décor or “sprinkle”) for the Moon

Earth Gets Spicy

Earth Gets Spicy

c) two peppercorns or allspice seeds for Earth and Venus

 

Having a Ball with Jupiter

Having a Ball with Jupiter

d) one jacks-size ball (Jupiter)

This jellybean could be Uranus or Neptune

This jellybean could be Uranus or Neptune

e) two jelly beans (or coffee beans) for Neptune and Uranus

 

Saturn represented by a large swirly peppermint

Saturn represented by a large swirly peppermint

f) and a ¾” (19mm) “shooter” marble or a big round piece of candy (also 3/4″ or 19mm) for Saturn.  (It’s just so nice to have something extra-cool and colorful for our most spectacular planet.)

 

 

Total cost: less than a dollar US; ideally, rummaging about an average home or allowing participants to bring contributions should turn up most of these objects for free. To splurge, pick up a whole jar of fresh peppercorns for around $5 and share them out among the students.

2) Eleven inexpensive holders for your objects, with the object names written on them. Empty clear yogurt containers or plastic drink cups work very well (see photos), as the pins can be pushed through the cups and others attached with glue to the cup bottoms…such that the cups then serve as mini-pedestals for the model objects. However, don’t feel bound by guidelines here—a set of index cards will do the job if that’s what you have handy. It does help to secure each object to its support. However, be sure that students can see the actual object clearly so that everyone has a feel for the scale. Cost: as much as 10 cents

3) A few signs printed on regular-sized paper to leave with objects that will be waiting for your return, such as:  “Please Leave This Experiment Undisturbed — (Teacher’s Name).”   Cost: 10 cents

4) Weights to keep each sign from blowing away in a breeze—anything from a handy rock to a water bottle to an actual sports-field marker from your supply closet.   Cost: negligible

5) Your basic first-aid kit and/or other equipment required by local protocols for a field trip.

6) Water as needed (Up to $10 if you need to buy each student some bottled water; negligible if students can bring refillable water bottles.) You may choose to make the walk as short as a half-mile (kilometer) or as long as twice that. For a short walk, you should only need modest supplies; for a long walk, snacks and water will be welcome.

7) A printout of your “Cheat Sheet” for either the English-units or SI-units version of the project Walk to Pluto, Miles or Walk to Pluto, km   (Just click to download the desired document) Whichever measurement system you’re using, it’s just one sheet, front & back, and includes short comments you can make as you take your trek. Cost: 15 cents, if your printer ink is expensive, because it does have colors.

Total cost of essential supplies: normally about a dollar, assuming most items can be gathered at home or borrowed.   For bottled water, if needed, budget an additional 50 cents per student

If you purchase all new supplies, you could spend as much as $40 for a brand-new soccer ball, a jar of nonpareils, a jar of peppercorns, a packet of pins, a jacks game, a bag of marbles with a shooter, and a package of jellybeans.

Interested in more details about the project calculations?  Here are copies of the complete worksheets:  Walk to Pluto Databank, miles and Walk to Pluto Databank, km

(For workbook copies in Excel format, ready for editing, I can send you a copy via Facebook messaging.  Just connect to one of my pages, Pixel Gravity or Cometary Tales.  Say, while you’re there, “like” the page.  Either way, you’ll receive the file in a return message.  The beauty of this approach is that you don’t even need a copy of Excel to use the workbook—Facebook will prompt you to choose whether to open it in Office Online or to download it.  The alternative is to email me via cometary@cometarytales.com.)
