Winecup flower center

with 26 comments

In this closeup of a winecup (Callirhoe sp.) at the Lady Bird Johnson Wildflower Center on March 25th the shadow struck me as appropriate for the profile of a gnome or ogre or some such creature.

It’s common to hear politicians and activists bandy about the phrase “common sense.” That’s a loaded and misleading term because some or even many things that a majority of people believe to be common sense are easily shown to be untrue. Over the next week I’ll give some examples, starting now.

Suppose you live in City A. One morning you get on an Interstate highway, drive to a place in City B, and with light traffic you end up averaging 70 mph for the trip. Three days later you return along the same route, but this time traffic is heavy, and in addition rain pours down for much of the time. As a result, you end up averaging a pitiful 30 mph for your return trip from City B to City A. Now here’s my question: what was your average speed for the round trip? Most people who are given these facts and asked that question will say the average speed for the round trip was 50 mph, which they got by averaging 70 and 30: 70 + 30 = 100, and 100 ÷ 2 = 50. It’s common sense, right?

So simple, so easy—and so wrong! People who come up with an answer of 50 mph don’t understand what an average is. An average is the total of one kind of thing divided by the total of another kind of thing. The very label “miles per hour” tells you what to do: take the total mileage traveled on the round trip and divide by the total number of hours spent doing it.

Let’s suppose City A and City B are 210 miles apart. Driving that 210 miles on the way from A to B at an average of 70 mph took you 3 hours. Returning another 210 miles from B to A at an average 30 mph hour took you a whopping 7 hours. The total distance you drove was 210 miles out plus 210 miles back, or 420 miles. The total time you spent was 3 hours out plus 7 hours back, for a total of 10 hours. As a result, 420 miles ÷ 10 hours gives an average speed of 42 miles per hour for the round trip.

Now, most people’s “common sense” would probably have them objecting: Wait a minute, not so fast (which is a convenient play on words in an example about speeds). These people would assume the average speed depends on how far apart City A and City B are. Well, in fact it makes no difference at all how far apart City A and City B are. Pick any distance you like, do the same kinds of calculations I did (which may mean you’ll need to pull out a calculator because the numbers probably won’t come out so pretty), and you’ll still end up with an average of 42 mph for the round trip.

The reason the true round-trip average speed ends up below the “common sense” but wrong average of 50 mph is that you spent more time driving at a slow speed of 30 mph than at a fast speed of 70 mph, and that pulls the average speed down. In summary, the truth is that despite “common sense” you can’t generally average averages.

Return to the cliff: textures

with 28 comments

Beyond orange and green things, I mostly focused on geological textures during
my January 16th return to the cliff along the Capital of Texas Highway south of FM 2222.

In the next picture, those among you of the pareidolic persuasion may see
a right-facing profile in the shadow, perhaps even that of George Washington.

And let me close by pulling back to a more expansive view showing an especially photogenic portion of the seeping cliff. At its top you see Ashe junipers (Juniperus ashei), seemingly ubiquitous in many parts of Austin.

Like a lion

with 56 comments

This rock formation reminds me of an animal’s head, most often a lion’s.
I photographed it along a tributary of Bull Creek in Great Hills Park on June 24th.
Hail, hail, not Freedonia but pareidolia.

Surprise on a ten-petal anemone

with 33 comments

I inaugurated the new wildflower season here with a post showing a ten-petal anemone (Anemone berlandieri) that I photographed on January 28th. As each fertilized flower matures, a lengthening seed column develops in the center, and eventually the sepals fall off. That was on its way to happening to the anemone in today’s picture from February 18th. When I moved in to make my portrait, I discovered that a crab spider had gotten there first. Those of you inclined to pareidolia may well see a face in the upside-down spider’s abdomen.

Shadow as an emblem of a bird in flight

with 45 comments

Along the North Walnut Creek Trail on the morning of September 19th I looked down at a mushroom and saw a dark bird winging west. Oh, the world of illusions we live in. Casting the magic shadow spell was a straggler daisy plant, Calyptocarpus vialis.

New Zealand: the retrospective from a year ago concludes

with 20 comments

Well, folks, it’s been fun reviewing some of the sights and sites that made our 2017 visit to New Zealand so memorable. I’ll admit it’s not hard to do that in such a scenic country.

Like the past several posts, here’s a last one from Cathedral Cove on March 7th. It’s something that Georgia O’Keeffe might have felt right at home with if you allow dried-out driftwood to take the place of a sun-bleached animal skull.

I’d planned to take pictures for one more day on this trip, and in particular I wanted to go back to Whangaparaoa, where I’d seen some colorfully appealing patterns on Little Manly Beach in 2015. Alas, even as we drove back to Whitianga from Cathedral Cove, drops began to fall (look at the dark sky in the upper left of the photograph), and the rain continued heavily all through the night. When we went to check out of our apartment the next morning to head for Auckland, the manager told us that so much rain had come down that both roads off the Coromandel Peninsula were washed out. We ended up spending an extra day in Whitianga with little to do, given the yucky weather. By the morning of March 9th, one of the two roads off the peninsula had reopened and we made it to Auckland with a few hours to spare before we had to check in at the airport for our flight home. Adiós, New Zealand.

New Zealand: the glow not of worms but of day

with 39 comments

A year and a day ago we visited the Kawiti Caves in Waiomio to make up for something we’d missed on our first New Zealand trip: the famous glowworms. I couldn’t record that sort of glow on a public tour, so I turned my camera loose on what the glow of day revealed outside the caves. Mostly that meant native bush and boulders. (If we extend the scope of “native” to include “boulders,” we can ask whether there’s such a thing as a non-native boulder? I guess a large meteorite qualifies.)

I couldn’t decide which of two prominent rock formations to show, so I’ve included both. At the far right in the second view a few of you may see a pareidolic head akin to New Hampshire’s Old Man of the Mountain, which collapsed in 2003.

What most caught my attention outside the glowworm caves was the old man’s beard lichens (genus Usnea) hanging conspicuously from some of the trees:

Just a month before I came upon this beard lichen in New Zealand, I photographed a species of Usnea an hour east of Austin.

A hoodoo begets a head

with 18 comments

Click for greater size.

This heady panorama is from the morning of September 3rd at Dinosaur Provincial Park, Alberta, where strange cloud shadows in the sky had greeted us a couple of hours earlier.

If you’re interested in the craft of photography, point 6 in About My Techniques is relevant to today’s picture.

Camel Rock

with 19 comments

Here’s a view from June 10th showing Camel Rock, a landmark on the main highway some 11 miles north of downtown Santa Fe. When I first visited Camel Rock nearly half a century ago, anyone could walk up to it and even onto it. Now I found the structure ringed by a fence. While I appreciate the protection, the fence made it hard to take pictures because I couldn’t get close enough to stand or sit where I wanted to. Oh well, I did what I could, aided by one of those famous New Mexico sunsets.

Do you see the rocky outline of the camel, complete with a hoodoo for a head and neck? If you’d like a look back at other pareidolic images that have appeared here in 2016 and 2017, click “pareidolia” in the “Tagged with” section at the bottom of this post and scroll down through the results. (There are bound to be instances in older posts as well, but I learned the term pareidolia only last year.)
