Never Stop Thinking

Posted on by

I think of an experiment to test a theory.

As I age, I find that my mind often wanders into different directions, normally unbidden. I think it’s because I have very little in the way of distractions in my home: I live alone and I don’t have a TV going all the time. This gives me time to think — and sometimes I think about unusual things.

The Science of Hot Coffee

This morning, I thought about why it was so important for me to warm my coffee cup before brewing coffee into it and why it was equally important to get the metal teaspoon I use to add sugar and stir out of that cup as quickly as possible. It all has to do with temperature: keeping that coffee hot as long as possible so I could enjoy it at my own pace before it got cold.

The warmed coffee cup is pretty obvious — we’ve all had the experience of putting a salad on a dish still hot from the dishwasher. The salad touching the plate isn’t as cold as the salad that isn’t. This is why they chill salad plates (and forks) at good restaurants. It follows that putting something hot into a cold vessel will do the same. I guarantee you’ve experienced this yourself. I know only one other person who takes the time to warm his coffee cup before putting coffee in it.

(And yes, I know a lot of folks don’t give a damn about what they likely consider a minuscule temperature change. But I do.)

But the spoon? Why is it so important for me to remove the spoon quickly?

This morning I thought a little about that. I’d always assumed that the stainless steel teaspoon would act as a heat sink. One end is in the hot coffee and the other is in the relatively cool kitchen. The heat from the coffee would heat up the spoon, which was made of metal — an excellent conductor of heat — and that heat would travel up the spoon handle to its end. The handle, which was constantly being warmed by the coffee would be constantly cooled by room temperature. That heat energy that is lost would have to come from somewhere: the coffee.

This is something I’ve always assumed. It makes sense to me. But this morning, for some reason, I wondered if I was right. And then I came up with an experiment to test my theory.

The Scientific Method


Scientific Method diagram by Wikipedia user Efbrazil used via CC 4.0 license.

I was in fifth grade when I learned about the scientific method. That was a long time ago and, not being a scientist or in any way involved in lab work my entire life, you’d think I’d forget it. But some things just stick with me. I think the scientific method stuck with me because it made sense logically — and I’m definitely a logical thinker.

Don’t worry — I won’t go into the scientific method in detail here. I’ll just focus on this diagram, which shows all steps to the method. The important concept to take away from this is that it starts with a question you might want answered and then goes through the process of coming up with a possible answer (hypothesis) and testing that answer (experiment). If the results (analyzed data) support the hypothesis, you might be done; if they don’t, then you’re definitely not done. In either case, you’d likely explore other hypotheses, going through the process again (and again and again, if necessary) until you either couldn’t get an answer — i.e., the experiment results simply do not support any hypothesis — or you were confident that one of your hypotheses was correct.

When I thought up an experiment to test my theory about a stainless steel teaspoon as a heat sink, I realized I was using the scientific method. In real life — not in a lab, not as a scientist. It was a great example about how some of the stuff we learn in school that we don’t think we’ll ever use in life does become relevant every once in a while.

Want to see the process for my experiment? Here are the first four steps:

  1. Observation/Question – More of a question: does coffee get cold faster if you leave a teaspoon in it?
  2. Research Topic Area – Well, understanding what a heat sink is is probably important to forming a hypothesis.
  3. Hypothesis – Yes, coffee does get cold faster if I leave a stainless steel teaspoon in it than if I don’t. (This would not apply to a plastic teaspoon since plastic is a poorer conductor of heat than metal.)
  4. Experiment – Take two identical cups. Add an equal amount of boiling water to each cup. Put a room temperature teaspoon inside one cup. Take temperature readings every 5 to 10 minutes to see if the one with the teaspoon gets cold faster. (You could expand the experiment to include three cups and put a plastic teaspoon in the third to test the hypotheses that plastic teaspoons would not have an effect.)

That’s as far as I got. I thought up the experiment but I didn’t do it. It simply isn’t that important to me to know, one way or the other, if I’m right. But it might make a nice at-home experiment for home-schooled kids if you happen to know any. Science is important — and heat sinks are a part of our every day life — they’re inside every computer we own.

Why Blog about It?

Why am I blogging about this? Well, I think I surprised myself this morning by my train of thought and where it led me. I wanted to share that with other folks who might find themselves consumed with things that prevent them from thinking for themselves.

All for clicks and likes

Let me take a moment to mention how outside pressures, especially from social media, get people to do things just for clicks and likes. Just this morning, I read another gender reveal tragedy story — too many gender reveals exist solely to impress others with their outrageousness. People are dying because a blog post that went viral has convinced people to make their own viral moment centered around the gender of their unborn child. Are we really that dumb? That 15 minutes of fame can put lives at risk?

This is an extreme, of course, but think about the not-so-smart things you’ve done to impress your friends and others over the years. Those “watch this” moments. Ever think of why you were really doing them? Or what the consequences could have been if what you did backfired? Is it really that important to impress others?

How about impressing yourself instead?

Every day, we’re faced with a barrage of inputs from family, friends, strangers, advertisers, and the news media. Direct conversation, text, and email; social media posts by people with their own agenda; print, audio, and video advertisements on billboards, in magazines, and everywhere online and on television; network and cable news broadcasters. Too much of that input is trying to fill your head with someone else’s thoughts and ideas and manipulate your opinions. If you follow politics at all, you know exactly what I mean. It’s hard to have a moment to yourself, a time to just think based on verifiable facts and to form your own ideas and opinions.

I do this a lot. Yes, I spend a lot too much time on Twitter but that’s the only social media I allow access to my brain. (Seriously folks, #DeleteFacebook.) And even then, I’m careful about who I follow. I don’t want a diet of political nonsense from either side so I tend to avoid accounts that post just politics. Instead, I try to get tweets from fellow thinkers — or at least from folks who have a life that doesn’t revolve around cable news and the latest political/celebrity scandal. And when I’m not on Twitter — which really is most of the time — I keep active and work on ways to make my life fulfilling.

I think therefore I am. If you can’t think for yourself, do you really exist?

Anyway, does leaving a stainless steel teaspoon in your coffee make it cool faster? If you do the experiment, let me know.

A Walk in the Woods

Another day, another hike with new friends.

One of the few things I miss about Arizona is the hikes I did with the Phoenix Atheist Meetup Group (PAMG). This 1700+ member group has a small subgroup that goes hiking in Arizona almost every single Sunday of the year. I began hiking with them when I returned to Arizona in September 2012 after my fifth summer work season in Washington and hiked with them periodically throughout the autumn, winter, and spring months. With them, I explored the area around the Superstition Mountains, Sedona, Prescott, Flagstaff, and even Wickenburg. They’re a great group of people — smart, friendly, educated, and open-minded. I made a lot of new friends that last winter in Arizona and already miss some of them very much. If you live in the Phoenix area and are looking for a group to hike with, I highly recommend meeting up with them. Tell them Maria, formerly of Wickenburg, sent you.

Although there are plenty of hiking opportunities here in the Wenatchee area of Washington, finding folks to hike with wasn’t quite as easy. Wenatchee is a much smaller city than Phoenix — although it’s much larger than Wickenburg — and there aren’t as many meetup groups. I did join a few that sounded promising. Among them is the NCW Freethinkers, which is based in nearby Cashmere, WA. (NCW, by the way, stands for North Central Washington, the commonly used label for the area where I now live.

At a recent pot luck BBQ meetup in Wenatchee, I told the group about my hikes with PAMG. Another member had been thinking of hiking as a group. He rose to the challenge and came up with the hike we did Sunday, to Clara and Marion Lakes.

Getting There

Lupine
Lupine is still blooming in the higher elevations near Wenatchee. A splash of sunlight illuminated this plant while leaving the forest behind it in relative darkness.

Western Monkshood
According to the National Audubon National Society Field Guide to the Pacific Northwest, this is Western Monkshood.

Heart-Leaf Arnica
According to the excellent Washington Wildflowers iPhone app, this is Heart-leaf Arnica.

Purple Monkey Flower
This Purple Monkey Flower was past its peak of bloom alongside a stream. Still beautiful, though.

Getting there was quick and easy for me — I was less than 10 miles away.

The trailhead is at the Mission Ridge ski resort’s lower parking area. Just take Squilchuck Road until it turns into Mission Ridge Road and keep going to the end. I currently live about two miles off Squilchuck so I was likely the closest hiker.

The road winds up into the canyon, past orchards and into the tall pines. There are amazing views back into Wenatchee from most bends in the road. Along the way I passed the turnoff to Beehive Lake, which I’d explored by Jeep only a few days before, and another trailhead I’d hiked with Penny the previous year. It’s amazing to me how much there is to do outdoors so close to where I live.

I arrived right on time after handling a few bee-related chores earlier that morning. Four other hikers were waiting for me. There were two other dogs, too — a 120-pound Rottweiler and a smaller Border Collie mix that reminded me of my dog, Charlie, left behind in Arizona. (Poor Charlie probably spends far more time curled up on a dog bed in front of a television in a Scottsdale subdivision than running around, off-leash, in the woods.) While I chatted with the other hikers, Penny tried to make friends with the other two dogs. The Rottie ignored her completely while the Border Collie immediately began playing with her.

I could tell then that it would be a good hike for both of us.

The Hike

When it became clear that a sixth hiker who’d RSVPed would not be showing up after all, we hit the trail. It immediately began a relatively steep climb with occasional switchbacks in a dense alpine-like forest. There were pine and other trees and dense underbrush. The air was cool and the sound was hushed. Wildflowers typical of the Pacific Northwest — which I still need to learn! — added splashes of blue, yellow, red, and white along the way.

I took up a place near the rear of the group, stopping more than a few times to take photos along the way. Although my uphill hiking endurance is far better now than it was when I was a fatty, I still need an occasional rest stop to catch my breath on steep climbs. Framing shots with my camera offered a good excuse to do so.

The Rottie and his owner led the pack, setting a brisk pace for all of us. Meanwhile, Penny and her new friend, now off-leash, began a chasing game up and down the trail. I swear those dogs covered three or four times the terrain as the rest of us.

The trail leveled off when it intersected with the Pipeline Trail. That’s also where it crossed a small rushing stream of snowmelt coming from somewhere high above us on the mountain. After taking a short break near the stream, we continued the climb on the narrow trail up to the lakes. Either it wasn’t quite as steep here or I was getting used to it because I had no trouble keeping up and needed fewer and fewer photo/rest stops along the way.

After a while, we came upon an open marshy area. We thought it was Clara Lake, dried up. But a post-hike examination of my route (tracked via GPS) shows that it was just an unnamed marshy area.

Near Clara Lake
Silly us. We thought this beautiful, flower-filled marsh area was a dried up Clara Lake, but that lake was still ahead of us on the trail.

Clara Lake Shore
Along the shore of Clara Lake.

Swimming Rottie
Not only did the Rottweiler (appropriately named Tanker) like to fetch sticks, but he didn’t mind swimming to get them.

Penny the Adventure Dog
Penny, as usual, kept ahead of me on the trail. It was such a pleasure to walk in the cool shade of the forest. When I lived in AZ, I dreamed about hiking in places like this.

The lake we came to a short while later was Clara Lake. Surrounded by tall pines and bordered on one side by a slide of volcanic rock, the small lake featured clear clean water and a collection of floating logs. We paused for a while and watched Mike’s dog swim to fetch large sticks, then moved to a shady area on the other side of the lake for a rest and snack. Some of us wandered around the vicinity.

Because we thought we were at Marion Lake — the second of two lakes on the trail and our intended destination — we didn’t go any farther. Looking at my GPS track now, I see that another 1/4 mile up the trail would have brought us to another lake. Oh,well. I think I’ll make that another hike, perhaps in the autumn when the trees are changing color. There’s another trail to the lakes down from a forest road that’s not quite as long or steep.

We headed back the way we’d come a little while later. It was a lot easier — almost all downhill. But steep! My knees really felt it. (I fully expected to be in serious pain the next morning — especially in my calves — but my body surprised me and took the workout without complaint.)

As usual, the hike back was quicker than the hike up. We passed several mountain bikers along the way — they were all walking their bikes up the steep trail. I wondered where they planned to ride and whether the ride down would be as wild as I envisioned. I also thought of the trail’s winter use — for snowshoeing. That’s a sport I might need to explore if I decide to spend winters here. I’ve already decided to get a new set of cross-country skis and explore trails in the Leavenworth area.

Back at the trailhead, the group split up. Although I was invited to join the others for beers at a local microbrewery, I decided to head home for a shower and a little R&R instead. I’d been running myself ragged for the past week and needed a break.

Besides, I’d promised a winemaker friend that I’d come visit her for a tasting that weekend and the weekend was almost over. I still had plenty on my calendar for the day.

Canyon Hike with New Friends

Nature + intelligent people + good conversation = a great time.

One of the reasons I’ve been so unhappy living in Wickenburg over the past few years is the lack of friends my own age who have similar interests.

As the years went by and Wickenburg shifted from being a ranching/tourist town to being a retirement community, all of our young friends moved away. There was Barb and Barry, who moved to New Mexico. Then Janet and Steve, who moved to Colorado. Then Lance and Keri, who moved to (of all places) Michigan. Some of our young, seasonal friends — John and Lorna come to mind — prefer hanging out with the old folks at the retirement community where they park their RV for half the year, opting for an ice cream social over a Jeep ride in the desert or a coffee gathering over a hike up Vulture Peak.

Because the town doesn’t offer enough employment opportunities for young people, it’s population continues to age, with more older folks coming here to retire, at least seasonally. I — or we, I guess I could still say — have quite a few friends old enough to be my parents. Sadly, most of these folks are not nearly as active as we are. And every year, when I return from my annual migration to Washington for work, I discover that one or more of them has died: Pete, Bill, Danny — rest in peace.

It’s depressing for someone like me who wants to remain active. While it was tolerable while I still had a husband at home — at least we could do things together on weekends — with him gone, the situation is bad. I decided to get proactive to find some friends.

I turned to Meetup.

Meetup

Meetup is a social networking service that makes it easy to find and meet up with — in person — people with similar interests for all kinds of activities. I’ve been a member for years and, in the past, have used it to hook up with a photography group based in the Phoenix area and a social group in the Wenatchee area. Last week, I worked it hard, looking for Meetup groups that might do activities near where I live. I didn’t expect to find any in Wickenburg — indeed, there are no Meetup groups within 25 miles of Wickenburg — but I found quite a few in the Phoenix area that do activities all over the state.

Last week, after hitting the Arrowhead Mall for a makeup consultation, I joined the 39 and Holding Club‘s “Hump Day” dinner, which was being held at Chili’s in Surprise, AZ. Although it was more than 30 miles from my Wickenburg home, it was still on the way home from the mall. It was a nice evening out with pleasant people. I met an interesting woman — I’ll call her “M” — who is also going through an ugly divorce that has been going on for two years now. (I sure hope mine doesn’t take that long.) M is the one who told me about Couch Surfing, which I linked to in one of my “Interesting Link” posts. So not only did I get to spend a nice evening out with new people, but I learned about some services I might want to take advantage of in the future.

I signed up with a bunch of groups for a bunch of activities ranging from wine tasting/pairing to hiking to archery lessons. My calendar is now quite full. And with new activities listed all the time, I don’t think I’ll have much trouble at all finding something interesting to do with others.

The Phoenix Atheists

I don’t usually blog about my religious non-beliefs because it results in a firestorm of comments by religious fundamentalists damning me to hell or worse. Of course, this means nothing to me because I don’t believe in hell. If you feel your anger rising now, take your blood pressure pills and move along. Comments blasting me (or others) for religious beliefs (or non-beliefs) won’t appear on this blog, so don’t waste your time posting them.

Yes, I’m an atheist. If you’ve been reading this blog regularly for a while and have somehow missed that point, shame on you. It’s not as if I hide it. If this is news to you and it upsets you, I’m sorry. I’d like to assure you that I have very strong moral convictions that don’t require an all-mighty being to supervise. I’m not a militant atheist — one who’s blasting believers all the time — I’m a live-and-let-live kind of person. If you want to believe in god, fine. Just don’t expect me to do it just because you and others do.

That said, I believe that atheists or “freethinkers” or “secular humanists” or “skeptics” — some of the names we apply to ourselves — are generally better educated, more intelligent, and better able to reason things out than the average person. I’m not saying all atheists are smarter than everyone else. I’m just saying that as a group, they tend, on average, to be brighter than the general population, better able to think before speaking, and better able to express their thoughts without offending others.

I’m not a dummy and I like talking to smart people. I like talking to people who are as smart as or smarter than me. People who can challenge me to think in a conversation. People who are able to discuss things deeper than what they saw on television last night, what’s in the news, or what they got in the latest Obama-bashing (or Romney-bashing) email in their in box. People who make me think about things that are interesting or important. People who can help me get a new angle on things, to possibly see things in a new way and build my own new conclusions. I like talking to people who can challenge me to think and to discuss things as an equal.

atheists.jpgI figured that a group of atheists should fit the bill. So when I found out that The Phoenix Atheists Meetup Group was going for a hike at Grapevine Canyon in Mayer, AZ, I decided to join them.

Because the trailhead required a 1-1/2 mile drive down a narrow, rough road, I took my Jeep and offered up rides to anyone who didn’t have a high-clearance vehicle. I got a call from another member — we’ll call him “D” — who was driving up from Yuma in his Toyota. We agreed to meet at the shopping area at I-17 and Carefree Highway, which was on my way north to Mayer. At 7:00 AM yesterday morning, I loaded up Penny, a fanny-pack full of frozen water bottles and snacks for both of us, my camera, and my monopod, and we headed out.

I got to the rendezvous point early. I topped off the Jeep’s gas tanks, then parked by McDonalds and started looking for others in the group. Another Jeep was supposed to meet there. What I discovered is that the McDonalds there is a popular meet up place for all kinds of groups of people. I’d stop at a small group and say, “Are you here for the hike?” (I didn’t want to mention atheists because some people get silly.) One of the people in the group would respond, “No, we’re going off-roading up by Crown King. You can come with us if you want.” Or, “No, we’re going scuba diving. Want to come with us?” Or, “No, we’re with the Miata Club.” (No invitation there.) I realized that even if I had nothing planned, I could go to the McDonalds, ask around, and go with the group that seemed to be doing the most fun thing. Whoa.

I finally found the other Jeep driver, “G,” and his companion. Then D. We chatted, loaded up, and headed north on I-17 to Mayer. I followed G’s Jeep.

I thoroughly enjoyed my chat with D during the 45-minute ride to Mayer. He’s a civil engineer who works with traffic control — light timing, traffic pattern design, etc. We talked about his work and mine and about each of our divorces. He was very supportive and offered some general advice from his own experiences. Although we didn’t talk much about that — I really didn’t want to — our chat helped clear my head and put me in a more positive mood for the hike ahead.

At the turnoff, there were more members of the group. I took on another passenger and followed a Toyota FJ Cruiser down a mildly rough road, with G’s Jeep taking up the rear. At the end of that little drive were more people and vehicles. I think our group wound up with a total of 14 hikers. A good sized group.

We parked and unloaded our gear. After a briefing from the group leader, we started off up the trail.

HikeArea.jpg
After driving down a rough forest road and parking, we did our hike in the area marked in red. We followed Grapevine Canyon most of the way.

We were on the eastern foothills to the Bradshaw Mountains. The Bradshaws aren’t very big — I think the tallest peaks might be around 6,000 feet — and the hills climbing up to them are mostly metamorphic rock and low bushes such as holly and manzanita. I kept Penny on her leash, mostly because there had been talk of mountain lions in the area and I didn’t want her wandering off. She walked with us like a little champ and only had to be lifted over one fallen log.

The trail started as a road, then narrowed to a wide trail. At a marked fork, we took the left fork, which was supposed to be level. It wasn’t. It climbed pretty steadily but not too steeply. Because we were hiking near a dry stream bed, there were some tall tress, including oaks and various pines. Scattered clouds and the trees helped keep the sun off us. Still, I’d dressed wrong in a pair of jeans instead of shorts. It wasn’t long before I was working up a good sweat.

Hand-carved Slingshot
We found this hand-carved slingshot hanging from the vertical poles of what may have been a hunting blind in a clearing along the trail. Magnificent workmanship! Of course, we left it where we found it; I hope other hikers do the same.

Members of the group split into smaller groups and chatted as they walked. Occasionally, the front groups would stop to let the stragglers catch up. It was very rewarding to me to be able to get into a conversation with any group I wound up walking beside. I was never excluded, other members seemed to go out of their way at times to engage me in conversation. It was exactly what I wanted from the experience: a good workout with good conversation.

Meanwhile, as the trail narrowed and climbed along the dry creek bed, it became tougher to follow. Soon, we were following cairns — piles of rock left to mark the trail. After a while, I was glad I’d worn long pants — others were getting their legs scratched walking through brush. Penny kept up very well, surprising me and others.

Eventually, we reached a dry waterfall with a seep-like spring. Thick green moss, which is rare in the desert, carpeted the rocks. Small flowers bloomed here and there. Butterflies flitted about. Facing an even narrower trail up the canyon, about half of us settled down to wait for the others to continue their explorations. Because various members had hand-held radios, we were able to keep in touch with all the groups. It wasn’t long before they’d had enough and began coming back.

Flower in the Sun
I captured this flower in a beam of bright sunlight.

The hike back was easier, probably because it was mostly downhill. Again, I found myself walking with different people along the way, talking about different things. It really helped keep my mind off my personal tragedy and the pain it was causing me. Being able to meet and talk to so many interesting people really pumped up my spirits.

Penny Resting on a Hike
We stopped for a long rest on the way back, mostly to gather the whole group together. I took this opportunity to give Penny some more water and let her rest.

Afterwards, we went to Leff-T’s Steakhouse in Dewey. The group insisted on us sitting on the outdoor patio so Penny could join us. I’m in the process of weaning myself off my diet — I’m very close to my final weight goal — so I ordered steak fajitas and ate about 1/3 of the portion, taking the rest home for the next two days. One of my companions kindly gave me a taste of his chicken fried steak — I love that stuff but will probably never be able to enjoy a full portion again. (Which really is a good thing, after all.)

We split up after that. D and I climbed back into the Jeep with Penny and headed back down toward Phoenix. Although it probably would have been closer for me to drive through Prescott, I admit that I looked forward to D’s company for part of the drive. We talked a lot more about what I was going through — he seemed genuinely interested and offered up all kinds of supportive words and advice. He also gave me some specifics about his post-divorce recovery process that I could apply to my own life and what I might face. It was extremely helpful to me.

After I dropped him off at McDonalds, Penny and I headed home. It was hot — seriously, I don’t understand how people could bear to live in Phoenix when the temperature is still hovering around 100°F on the first day of autumn. We made good time getting back and I was glad to pull the Jeep into the garage just as it was beginning to get dark outside. I gave Penny a much needed bath and took a hot shower to wash off the day’s sweat and dirt.

I was tired but I felt happy and hopeful for my future.

I’m really looking forward to my next outing with this group.

Postscript:
HappyThe hike leader, Al, posted a huge batch of photos that he shot before, during, and after the hike. Among them was this gem.

The ugly divorce I’m dealing with right now has been eating away at me day after day and night after night. But Al managed to capture the truth in this photo: my spirit is still alive and strong, I can still have fun, I can still be happy.

Thank you, Al. Seeing this photo really made my day.
