Mother's Day


The years go by in a hurry when you're our age.

Yesterday our granddaughters lived up to family tradition and made some "Mother's Day" bread for their Mom. The breadmaking session was all part of my wife's making a large loaf for the granddaughters' piano recital which took place today.

At that recital, our older granddaughter played a moving interpretation of the "Moonlight Sonata", the younger one played a wonderful rendition of "the Lion sleeps tonight"; she also sang a medley of Beatle tunes. Both of them teamed up to sing a duet towards the end of that medley. Each has a beautiful voice (no bias here!) - we're proud grandparents.

Time goes by.

Since it was Mother's Day, the many mothers who go through a lot of effort to make it possible for the music students to attend the Crowe Music Studio were given their due recognition - as was Ms. Crowe (the teacher, mentor, confidante) herself. All her family was in attendance; they handed her a nice flower bouquet. It was nice to see them all. We've come to know Ms. Crowe as a wonderful and accomplished music teacher (she's also an examiner for the Royal Conservatory of Music) - and it showed in the calibre of the students' recitals. There is also another connection: Ms. Crowe and I both have German roots. When I drop off our granddaughters for their lessons, we occasionally converse in that language - to the apparent wonderment of most of the students attending her studio at the time.

Astronomy Day May 2, 2009

The Royal Astronomical Society of Canada (RASC), along with many other like-minded groups is "observing" Astronomy Day with a host of activities for all ages and involving many space-related topics. Here in the Vancouver area, telescopes, talks, and exhibits will be set up at the "Gordon Southam Observatory" (GSO), next to the Planetarium in Kitsilano. Here are a couple of links to further information:

The event will take place rain or shine. If weather permits, you can view the Moon, the planet Saturn, and other interesting astronomical objects through various telescopes.

The event is free to anyone.

Have an educational time!

A few travel notes

As mentioned in my last post, we've spent some time with friends in California, and travelled there by car. We returned yesterday, taking four days to come back, and driving along some of the roads less travelled.





While the American interstate highway system goes through some magnificent scenery (the view at left is of Mount Shasta), the smaller roads offer some wonderful, sometimes unexpected views of nature as well.


As an example, we stayed in Calistoga, a small city in the Napa Valley of California (this area is known as one of the top wine-producing areas in the world). The hotel was a beautifully restored place, reminiscent of high-class hotels of about 100 years ago, mixing "Art-deco" and "American-West" styled rooms with present-day wireless internet access, DVD players, and TV in every room.

On our way out, just outside of town, we stopped at a place featuring the smaller sibling of "Old Faithful" (in Yellowstone National Park, Wyoming), also called "Old Faithful", seen at left. This geyser erupts every ten minutes or so. Each eruption is preceded by about a minute of bubbling, gurgling sound, not unlike that of our electric coffee maker at home. The geyser is located on private land, so we had to pay some admission ($6 each); we considered it well worth the experience. Since we had arrived early, we were the only visitors and could look at the geyser, the museum and videos at leisure and without interfering with anyone.



During our travels, the other amazing thing to consider was the fact that all the roads on which we travelled were either blacktopped, or concrete-covered. The picture shows the road through a part of California's famous Redwood Forest. If you consider the immense road system in the USA alone, how much does this represent in natural resources and evironmental alteration? How could the majority of people learn to appreciate these natural wonders without such cost?






Our vacation ended on a beautiful and romantic note. We headed to Cannon Beach (Derek's family's favourite vacation spot), on the Oregon Coast, for our last evening "on the road". It happened to be the day of our 44th wedding anniversary. Accommodation was in a beachside hotel room with balcony, looking west over the Pacific Ocean. With a bottle of red Oregon wine, and a couple of piccolos of champagne, we had a nice, sunset French "Dinner" on the balcony (consisting of French bread, some cheeses and sausage, rather more like an elaborate picnic). This was a fitting end to a trip which included the reunion with many good friends and good times with them.

Southern California?

We have spent the last week here in San Diego visiting close friends. The occasion was a birthday get-together with some of the members of our "travel group" (we meet in various places at unspecified times). This time, my wife and I travelled here by car. On the way, we hit a lot of "unCalifornian" weather - strong winds and rain. It DOES rain in Southern California, notwithstanding the hit song of three decades ago. Fortunately, the days on which the birthday festivities took place, and on the day of the Easter Sunday brunch, the sun was shining and the temperature was more like what you'd expect. Today, it's cold and windy again, and it just rained for a few minutes. Feels more like home.

All this pales in comparison to better news. Derek's latest CT scan shows that his cancer has been stable over the last two months - as his parents that means more to us than anything.

Halo

This afternoon, I was sitting in the back yard, soaking up some sun. The sky was somewhat hazy. Momentarily glancing at the sky in the direction of the Sun (with my eyes shielded against it), I noticed a faint halo around the Sun. Here is the image, taken with a Canon Rebel Xt, 18-200mm Sigma zoom lens at 18mm, ISO 100, f22, 1/1000th sec exposure.

According to Wikipedia, a halo is an optical phenomenon that appears near or around the Sun or Moon, and sometimes near other strong light sources such as street lights. There are many types of optical halos, but they are mostly caused by ice crystals in cold cirrus clouds located high (5–10 km, or 3–6 miles) in the upper troposphere. The particular shape and orientation of the crystals is responsible for the type of halo observed. Light is reflected and refracted by the ice crystals and may split up into colors because of dispersion, similarly to the rainbow.

Disappointing Earth

On Saturday, the hour from 8:30 to 9:30pm was designated "Earth hour". The idea started in Australia, and its purpose is to cut down on energy consumption for that hour. In most cases, this means shutting off extra lights, computers, and other unused appliances in one's house.

We lit a few candles, shut off all our lights (we use the non-incandescent bulbs anyway), the network computers in our house, and did not turn on the TV, even though one of the programs we regularly watch was scheduled for that time.

I looked out our windows during that hour. Sad to say, I noticed absolutely no difference from the normal situation. All our neighbours' lights were on as usual, the highrises in our neighbourhood were lit up like Christmas trees (as usual), and the sky did not look one whit darker (it was as light-polluted as ever). If I want to be charitable, I'll say that most people did not even know about this hour; otherwise I have to assume that people around us just don't give a damn.

As it turns out, our city, along with many others, saved less energy this time than last year. What does that say about individual people's attitude towards "Global Warming" and climate change?

Hazy Astronomy

As I've mentioned before, this year is designated as International Year of Astronomy (IYA). To that end, the Royal Astronomical Society of Canada (RASC - I've been a member for more than 30 years) is undertaking many public activities, free for all to take part in. Worldwide, there are many astronomy associations and educational institutions involved in the same activities.
After several locally scheduled events were "rained out" lately, last night turned out to be more promising. A clear evening was predicted by Attilla Danko's "ClearDarkSky" program which uses data from Environment Canada's weather forcasting system.
Things turned not quite as clear as predicted - there were thin, hazy clouds drifting across the sky all evening. However, they were transparent enough to show the brighter objects, one of which was the planet Saturn. Three of us were slated to run this meeting, and two of us had committed to set up our own telescopes at the H.R. McMillan planetarium for this date, so I set up my Celestron C-8 in front of the Gordon Southam observatory. The third member in our group operated the observatory telescope itself.
This year, Saturn's rings are seen almost edge-on. That's a consequence of the tilt of Saturn's axis of rotation with respect the plane of its orbital plane and generally all the major planets' orbits. This presents some interesting viewing since some of Saturn's moons, most of which orbit Saturn in the same plane as its rings, can occasionally be seen crossing Saturn's disk, along with their respective shadows. Since the hazy clouds had a detrimental effect on seeing some of the very fine details through the telescopes, such an event would be somewhat difficult to perceive. However, the rings and Saturn's bright moon Titan were easily visible. To the left you see what Saturn and Titan looked like as seen through a telescope, at a magnification of about 90 power. Click on the picture for a larger view.
There were more than 100 people who took advantage of the occasion - some had been attending a show at the planetarium, others just happened to be out for a walk. Many had never had a look through an astronomical telescope, and were very impressed about what could be seen. It's amazing how interested people are in what's going on in space; many just don't know how to meet people with similar interests. So this get-together fulfilled its primary purpose of bringing these people together. Some enquired about how they could get more involved. Here is one possibility: the RASC member meetings and sky observing sessions are open to the public, and are free. If you become a member, there are a number of privileges which you'll enjoy. In Canada, for more information, go to http://www.rasc.ca/, and pick the link to your closest local centre. If you live elsewhere, look for an astronomy club in your area - IYA is a worldwide effort.
