Oamaru Public Gardens

We went for a morning walk in the beautiful Oamaru Public Gardens adjacent to our campground:

The Wonderland statue shows two children looking down at the fairies, elves and small animals in the ground below their feet:

There were many beautiful flowers, including these in Rhododendron Dell:

Not all of the pretty occupants of the gardens were plants:

There were many different parts of these gardens, including a native plant area, Chinese garden, gazebo, glasshouse, and more. We had camped the night before in the "Motor Camp Area" at the upper left, adjacent to the Croquet Greens:

Nov. 20 - Oamaru to Mount Cook

Today we drove from Oamaru on the coast to Mount Cook:

It was only about 130 miles, but there was so much to see and do! Posts for today:

Penguins at Oamaru

Six of the 17 species of penguins in the world can be found in New Zealand. (Click here for an excellent web site about penguins in NZ.) We saw two species at Oamaru.

There was a small colony of yellow-eyed penguins (Wikipedia entry, NZ DoC link):

These penguins are large (30 inches, 14 pounds) and somewhat endangered. They are solitary birds.

There was a larger colony of blue penguins (Wikipedia entry, NZ DoC link):

Blue penguins are the smallest penguins (16 inches, 2 pounds). They are common and they live in colonies. We also saw blue penguins at the International Antarctic Centre in Christchurch.

(Photos from Google Images. Our photos of a yellow-eyed penguin were so-so, and we were not allowed to take photos of the blue penguin.)

This was spring in New Zealand, and the penguin chicks had recently hatched. The nests with the chicks were on land. The penguin parents took turns out at sea during the day fishing for food, returning to their nests at dusk to feed the chicks. We saw the penguins as they were returning to land. The yellow-eyed penguins returned one at a time. The blue penguins returned in groups called rafts.

The blue penguins had established a colony in an old rock quarry, and there was actually a grandstand built to watch the rafts come ashore. We saw over 100 birds in three rafts come ashore. Click here for a web site about this blue penguin colony.

Oamaru

The coastal city of Oamaru became wealthy in the late 1800s due to its role in shipping frozen meat (mutton and lamb) to England. That trade no longer exists, but many historic buildings remain. Most of the buildings in this small city of 13,000 were built from a local limestone called Oamaru stone. This is a view of one of the smaller streets near the wharves:

For pictures of the more majestic buildings in the center of town, see the Wikipedia entry here.

Oamaru is hilly, like San Francisco (but smaller). This view is from a hill in town:

South of town is the Bushy Beach Scenic Reserve where a small colony of yellow-eyed penguins live (see next post):

Our first night of camping was at Oamaru. We stayed at the Oamaru Top 10 Holiday Park, our first of several stays at this chain. This photo, taken the next morning, shows the campervan with the sleeping pod on top extended:

Canterbury Plains

The direct route from Christchurch to Oamaru is State Highway (SH) 1. We read that it was more scenic to take an inland route, and so we took State Highways 73, 77 and 72 along the western edge of the Canterbury Plains, before returning to SH 1 near Temuka.

The Canterbury Plains lie between Christchurch on the coast and the mountains to the west—the Southern Alps. The Plains contain much agriculture, and the drive was indeed scenic. This is just outside Christchurch:

The Canterbury Plains are one big gravel bank that washed down from the glaciers in the mountains. I did not notice any land tilled for row crops, but there were endless pastures bounded by trimmed hedgerows and full of sheep:

...and dairy cows:

We also saw beef cattle and deer. Much of the pasture was irrigated:

On the western edge of the Plains, the road crossed the Rakaia River near the Rakaia Gorge. The color of the water is typical of glacier melt:

Spaceship Campervan

We rented a Spaceship Campervan in Christchurch:



The car was a Toyota Estima minivan (I think it's called a Previa here). It was well broken-in, with over 300,000 km. The "GPS" on the side of the van was its name. We did not use the Global Positioning System on our trip.

There are many campervan companies in New Zealand. Nancy chose this company because of the vehicle: 1) being a minivan it would be easier to drive than a large campervan (especially since we had to learn to drive on the left side of the road); and 2) it was available with a pod on top which could be cranked up to provide sleeping space for a third person.

"GPS" worked out just fine for us.

Nov. 19 - Christchurch to Oamaru

Today we rented a campervan in Christchurch and drove to Oamaru, about 180 miles:

Christchurch, New Zealand

Nancy and I are in New Zealand! We arrived in Christchurch early on Monday, Nov. 17, local time, with plenty of time left for sightseeing.

Emily met us at the airport and took us downtown. In the center of town is the Christchurch Cathedral:

I highly recommend the tower climb!

We stayed at the Sudima Hotel, next to the airport and also next to the International Antarctic Centre, which we toured on Tuesday. The Hagglund ride was great! We rode in the yellow one:

Later in the day Emily showed us Canterbury University, where she just finished the spring semester, and her flat:

On Tuesday evening we visited John and Margaret Porter:

John is my first cousin; he moved to Christchurch in 1987. Another family connection is that his brother David Porter worked at McMurdo Station in Antarctica for several years, and passed through Christchurch several times. The majority of people working in Antarctica leave from Christchurch. The United States, New Zealand and Italy have their headquarters for their Antarctic programs in a shared building adjacent to the International Antarctic Centre.

All of our travels on this trip are on the South Island. We started in Christchurch, toured around the South Island for several days in a campervan, and returned to Christchurch.

Freedom and Authority: Copenhagen

The "Freedom and Authority" discussion of the play Copenhagen at Parents Weekend at Colorado College on Oct. 11, 2008 was most interesting.

There are several posts on this blog about the play and the discussion.





Before Parents Weekend, I wrote 4 posts about the play:

Copenhagen, Part 1 - introduction to the play
Copenhagen, Part 2 - introduction to quantum mechanics
Copenhagen, Part 3 - Bohr's and Heisenberg's contributions to quantum mechanics
Copenhagen, Part 4 - how it all fits together

After Parents Weekend, I wrote 3 posts about the discussion:

Copenhagen Discussion, Part 1 - what is a "Freedom and Authority" discussion?
Copenhagen Discussion, Part 2 - what we talked about
Copenhagen Discussion, Part 3 - what we didn't talk about

The most interesting part to me was what we didn't talk about.

Copenhagen Discussion, part 3

Concluding comments on the "Freedom and Authority" discussion on 10/11/08 at Colorado College about the play Copenhagen...

"Bohr: Uncertainty and complementarity became the two central tenets of the Copenhagen Interpretation of Quantum Mechanics." (p. 70)

In my discussion group we talked a lot about uncertainty (Heisenberg's contribution), but we never talked about complementarity (Bohr's contribution). Both were central themes of the play.

In quantum mechanics, complementarity refers to the wave-particle duality of matter and energy. Einstein showed that matter can be converted into energy and vice versa. Quantum mechanics showed that matter and energy have both particle-like characteristics and wave-like characteristics. The principle of complementarity states that "a single quantum mechanical entity can either behave as a particle or as wave, but never simultaneously as both; that a stronger manifestation of the particle nature leads to a weaker manifestation of the wave nature and vice versa."

As I mentioned in an earlier post, it is dangerous to apply scientific concepts beyond their original meaning. But we do it all the time: the discussion of uncertainty as applied to human thoughts, intentions and memories is far beyond the mathematical expression of the uncertainty principle that Heisenberg developed. (See equations here.) Nevertheless we try to extend scientific principles into other areas because it seems to ring true. We should always keep in mind that it might not be true.

The application of the principle of complementarity beyond quantum mechanics was supported by Bohr himself:

Complementarity became his idée fixe, and Bohr began to see it everywhere. (source, p. 201)

Complementarity means that nature exhibits a duality. Quantum mechanics shows this at the most basic level of nature: elementary particles exhibit a wave-particle duality. Bohr was not the first to notice that nature often exhibits a duality: night-day, life-death, male-female. This idea goes back at least to the concept of yin and yang in ancient Chinese philosophy.

The highest order of the Danish government is the Order of the Elephant, awarded to Danish royalty and sometimes to foreign heads of state. It is rarely awarded to a commoner. It was awarded to Niels Bohr in 1947. (Tycho Brahe was another Danish scientist awarded this order in 1578.) Being a commoner, Bohr did not have a coat of arms and upon receiving the order he designed his own. His coat of arms featured the symbol of yin and yang at the center, and the Latin motto contraria sunt complementa (opposites are complementary).

Here is a picture (source):

Like the theme of uncertainty, a theme of complementarity also runs through the play: friend-enemy; mentor (Bohr) and mentee (Heisenberg); skiing fast (Heisenberg) vs. skiing slow (Bohr); mathematics (Heisenberg) vs. language (Bohr); Bohr and Heisenberg working together vs. working apart.

This theme of complementarity is particularly interesting given the context of the discussion itself at Colorado College. What better example of complementarity than "Freedom and Authority"?

Copenhagen Discussion, part 2

Continuing comments on the "Freedom and Authority" discussion on 10/11/08 at Colorado College about the play Copenhagen...

The discussion in my small group centered on three topics: morality, friendship and loyalty, and uncertainty.

I did not find the discussion of the first two topics interesting. There was much talk, but no enlightenment.

The discussion of uncertainty was more interesting. Quantum mechanics introduced a paradigm shift in the world. Before quantum mechanics, we thought the world was deterministic. After quantum mechanics, specifically Heisenberg's uncertainty principle, it appears likely that it is not. (Although Einstein did not agree with that conclusion, as Brian wrote about in a comment on this post. We did not get into any discussion of Einstein's views.)

A theme of uncertainty runs through the play: the uncertainty of our thoughts, intentions, memories. On this theme, one woman in our discussion group said that if you have ever kept a diary at any point in your life, and then you go back to read it years later, you will find that it is not what you keep in your head as memories from that time. I have noticed this myself when reading something that I wrote years earlier. Sometimes we remember incorrectly, but more often we simply forget. And if we cannot always remember accurately things that we took the trouble to write about at the time, how much less accurate is our memory of things that we didn't bother to write about at the time?

Copenhagen Discussion, part 1

The discussion of the play Copenhagen, by Michael Frayn, at Parents Weekend at Colorado College this past weekend was interesting. (See also the four posts in September, before Parents Weekend, about this play. First post here.)

This was a "Freedom and Authority" discussion. Freedom and Authority was an interdisciplinary class introduced at Colorado College in 1951, during the McCarthy era.

The course revolves around the quintessentially liberal arts questions, “What do I think and believe? And why?” “What is the balance between individual freedom and religious, social and political authority?” (source)

Originally a senior level course, it is now part of the First Year Experience program at CC.

Since 1959, Homecoming Weekend at CC has included a Freedom and Authority discussion for alumni. Parents Weekend and Homecoming Weekend are now the same weekend at CC, which is how I came to be involved.

I would guess that 150 people attended the discussion of Copenhagen. After some introductory remarks, we were split up into groups of 20 or so. We were supposed to discuss for 45 minutes in our small groups and then return to the larger group. My group talked for so long that we missed the larger group discussion at the end. I did not make any comments. There were plenty of other people who wanted to talk more than I did.

William Davis, professor of comparative literature and German, gave the introductory remarks. History professor David Torres-Rouff led the discussion in the small group I was in.

Slightly more than half of the overall group was alumni, and most of the rest were parents. In my discussion group, there was one freshman student. Prof. Torres-Rouff was the third youngest person in my discussion group (after the freshman and a 5-year alum); he was in his late 30s. There were lots of alumni from the 1960s.

One more thought on Freedom and Authority: the topic is similar to the Vermont state motto—Freedom and Unity. What is the proper balance between individual freedom and group unity?
