Recuperating

Derek had his chemo yesterday. Airdrie tells us that he spent most of the night sleeping - with the help of the anti-nausea drug, which seems to help quite a bit. He still has a bottle of chemo medicine attached until tomorrow, so he'll probably feel lousy for the whole weekend. This controlled poisoning is no fun for any of us, least of all Derek himself.


Today, our grandchildren set up our "Christmas village"

and helped with setting up the Christmas tree. It was a welcome activity for all of us.

Action

As you can imagine, we've had an anxious week. Today, Derek had an appointment with his oncologist. His chemo starts tomorrow. Understandably, he's not looking forward to the side effects, since he knows what to expect from his previous round of treatments. Apparently there is a new anti-nausea drug, though, and we're hoping that it will help diminish some of those side effects.

At least there is some action. It eases the anxieties a bit.

Thinking in the night

I am a light sleeper, and have inherited my sleeping patterns from my mother. Usually, I wake up around 2 a.m. Nowadays, at my age, nature calls me to the bathroom about three to four hours after I fall asleep anyway. I am usually awake for at least two hours after that. That's the time when I think through recent events and what I may be doing after I get up in the morning.

In the last few days, this pattern has been disrupted. The reason is obvious: Derek's cancer medication has become ineffective. Today, I was awake all morning from 2 a.m. on, thinking about Derek, Airdrie, Marina and Lauren, Airdrie's parents, us, our other family members - what is ahead? As Derek says in his blog post: Time to walk into the unknown future again.

Bad news

Today Derek and we found out that his cancer has grown substantially in his lungs.

This is devastating.

Back home

We were away in Germany for a couple of weeks and since our return, I've been catching up in my business. So today is the first chance I've had to relate some things related to the trip.



We attended the 40th wedding anniversary of close friends who live in an area not too far away from the North Sea, and had a Family meeting in Berlin as well. I have two aunts in their mid-nineties there, and we visit them as often as we can. One of them is my mother's sister - she's the last one of her siblings. She's in good shape, but unfortunately totally deaf. We communicate by writing our comments on paper. The other aunt is a former sister-in-law of my mother. Both she and my mother were widowed twice; in each case they lost their first husbands because of the second world war. She is slowly going blind, but lives in a first-class old-age home, has a friend there, and the two support each other.

I have another aunt in Vienna, also of that advanced age group. We didn't get there this time and we're hoping to see her next year, if our family situation allows.

It's important to maintain family connections.

The Ghouls at work

Last Hallowe'en night, we had a large number of kids, and also teenage "kids", collecting their "dues". We must have done something wrong, because, as I write this, we've been subject to a power failure for about an hour by now. We had another one about a week ago as well - before that, we hadn't had one in a long time. I suppose the ghosts are evolving along with our technology; how else, considering that they've been around since the dawn of humanity, would they know that a power failure would be exactly the right thing to stop us in our tracks and make us acknowledge them? Now I have to go around and reset all the digital clocks in the house AGAIN!

One thing the ghouls couldn't interrupt is my access to the internet. I connect through one of Rogers' portable modems, and I have backup battery power for it. I run my stuff on a laptop, So I can be independent of the power grid for this purpose at least. A small defiance...

Vancouver Harbour

Derek's post of October 13, referring to the change in the Vancouver skyline over the last 50 years or so prompted me to dig out a couple of my own pictures of the Vancouver harbour view. I photographed the top image in 1956, the bottom one dates from 2008. Both pictures were taken from the same spot (within a couple of meters, or so). While the cameras and angle-of-view for the two source images are very different, I made an attempt to crop and resize the pictures in such a way as to make them appear similar. Click on the image for a larger view.

The change is astounding. The only edifice I can discern in both pictures is the spire of the Holy Rosary Cathedral on Dunsmuir Street in downtown Vancouver. The arrow in the top picture points to it. You can also spot it among the high rises in about the same relative position in the lower picture.

The two tallest structures in 1956 are the Vancouver Hotel on the right, and the Marine Building on the left. Both buildings are still in existence, but they are obscured by the newer high-rise buildings which have since sprung up.

Ah, progress!!

Crash Landing

After much hype in the media, the actual preplanned collision of the LCROSS (NASA's Lunar Crater Observation and Sensing Satellite)with the Moon was a visual disappointment for me. At first I was contemplating setting up my 200mm (8 inch) telescope, using my "new" eye, but advance information suggested that the telescope would have to perform at its very limit, and in excellent conditions - i.e no light pollution, absolutely clear and dark sky (an impossibility in this light-polluted city of Vancouver). I therefore decided to watch the NASA coverage instead, if I were to wake up around 4:15 in the morning. Well, I did watch it, but the images sent down from the Moon did not show me any impact. I've watched the replay several times, but to no avail.


Later today, NASA published more pictures, after analysis and using images from a "medium infrared imager" (MRI) camera. It showed the impact a little better, but I saw no sign of the calculated 10km debris plume, which was to expose any water ice possibly located in the permanently shadowed impact crater.

(both images from the NASA website - click on them to enlarge)



Here is the impact image the way I saw it. It shows the visible light image - the way you and I would see it if we were on board of the LCROSS satellite. I can't identify any crash.








This is the MIR image. Infrared shows hot spots a lot better, but the human eye cannot perceive infrared light.



Here is an excerpt from NASA's media advisory describing the mission:

MEDIA ADVISORY : 09-131AR

NASA Spacecraft Impacts Lunar Crater in Search for Water Ice

MOFFETT FIELD, Calif. -- NASA's Lunar Crater Observation and Sensing Satellite, or LCROSS, created twin impacts on the moon's surface early Friday in a search for water ice. Scientists will analyze data from the spacecraft's instruments to assess whether water ice is present. The satellite traveled 5.6 million miles during an historic 113-day mission that ended in the Cabeus crater, a permanently shadowed region near the moon's south pole. The spacecraft was launched June 18 as a companion mission to the Lunar Reconnaissance Orbiter from NASA's Kennedy Space Center in Florida. "The LCROSS science instruments worked exceedingly well and returned a wealth of data that will greatly improve our understanding of our closest celestial neighbor," said Anthony Colaprete, LCROSS principal investigator and project scientist at NASA's Ames Research Center in Moffett Field, Calif. "The team is excited to dive into data." In preparation for impact, LCROSS and its spent Centaur upper stage rocket separated about 54,000 miles above the surface of the moon on Thursday at approximately 6:50 p.m. PDT. Moving at a speed of more than 1.5 miles per second, the Centaur hit the lunar surface shortly after 4:31 a.m. Oct. 9, creating an impact that instruments aboard LCROSS observed for approximately four minutes. LCROSS then impacted the surface at approximately 4:36 a.m.

A new view

Well, as mentioned in my previous post, I had cataract surgery on my right eye on September 30. The procedure itself was painless, although I liken the level of comfort during the operation to the experience of having your teeth cleaned by a dental hygienist - i.e. slightly discomforting.

The result is absolutely astounding, though, and well worth a bit of uneasiness. My right eye can now discern fine detail I haven't seen in decades. Since I'm into astronomy, that result is exactly what I had hoped for.

At the moment, I have to take some care - no heavy lifting, and an interwoven schedule of taking medication in the form of eyedrops - but I'm looking at the world with a new eye (pun intended). Until now, I hadn't realized how much I was really losing, when looking around, and am now aware that my left eye, which was the better eye lately (using glasses) would also benefit from this kind of operation.

So, at the moment, I'm using eyeglasses in which the left part of the frame retains the bifocal lens formulated for my left eye; I have removed the right-eye lens altogether. The result, for distance viewing, is a reasonably close balance between my two eyes, with the right eye outperforming the left one by a noticable margin. It also makes it possible for me to read the newspaper and books (and typing this story on the computer) because, at my age, reading glasses are usually necessary. My reading is done with my left eye, through the "reading section" of the lens. This is no problem for me, because my right eye had deteriorated to the point at which I could not use it for reading anyway.

If and when I finally get my left eye "restored" in the fashion described above, I won't need glasses for distance view (that includes naked-eye astronomy, and watching TV, for instance). For reading, I can purchase some of those inexpensive, off-the-shelf reading glasses available anywhere. I'll then use both eyes for reading and close-up viewing.

In short, from my experience, if you are contemplating cataract surgery, go for it.

Plugging along

My busy days (Sept 19) have continued. Our friends who reside in Mexico, have just returned from their Alaska cruise, and are staying with us.

Every now and then, there is a bit of a break in all this. For example, last Sunday, the Vancouver Centre of the Royal Astronomical Society of Canada hosted the Paul Sykes Lecture (an annual event, funded through an endowment from Paul Sykes), hosted a talk by Dr. Neil Turok - the eminent mathematical physicist, and collegue of Dr. Stephen Hawking. His topic related to the evolution of the early universe, which is one his fields of interest. Dr. Turok presented the subject in a most engaging, humorous way, and did not shy away from telling us how little concrete information we have - even though there have been astounding breakthroughs achieved in accumulating accurate data. My wife, whose interests only peripherally include astronomy, enjoyed the talk, and said so several times.

After the meeting, the RASC's council invited Dr. Turok to supper, and a few of the council members (of whom I'm one) joined in spirited, wide ranging discussions about the various aspects of theoretical physics. A good time was had by all.

The Paul Sykes lecture is free to the public - come and join next year.

Tomorrow I'm slated for cataract surgery - another break in the routine.

Busy time.

I run a business which involves many of the larger educational institutions in our area. Since school started earlier this month, I've been very busy, including weekends. In addition, we have good friends visiting, and staying at our home. That has meant no time for blogging. For those of you who may be wondering, both my wife and I are ok - we're just involved in our various activities at the moment. This is a chance to write a little note here, before I continue with business today.

A somber weekend

There are periods when personal events induce a state of introspection and contemplation.. This weekend was one of them.

On Friday, we attended the memorial service for a good friend, who died a couple of weeks ago. Kilby Gibson was my sister-in-law's long-time friend (the two of them roomed together in their early twenties), and we had gotten to know Kilby at one of our family get-togethers many years ago. My wife, my sister-in-law, Kilby, and her sister Sheila used to meet for lunch on a semi-regular basis. In the last seven years Kilby had been battling lymphoid cancer, but never lost her vivaciousness and fighting spirit. She was politically active at various levels, and contributed a great deal to the betterment of those around her. Our hearts go out to her husband Gordon and his family.

Everyone is aware of the death of Ted Kennedy in the United States. He was also someone who worked for and had a great influence on the policies regarding less fortunate people in the U.S., and in the world. While his fight for universal health care in the U.S. is still ongoing, he's certainly put this issue in the centre of that nation's political attention. He will be missed.

Within our own family, our son Derek's fight with cancer is always on our mind. There are times when we all get a feeling of sadness (and rage) because of the unfairness of it all. This weekend was one of those times.

Time with the granddaughters

Since Derek and Airdrie are at Gnomedex, we have our two granddaughters to look after these days. Thursday we explored the new Canada subway line to the airport, yesterday we spent all day at the PNE (we sat on the grass for the "Beatle Anniversary" performance, too). Big crowds.



The "Canada Line" day was an all-day event for us. We decided that four of us would take public transport to get to all the places we were going to visit. The "Skytrain"is our elevated/subterranean remote-controlled light rapid transit line which has existed since the year of "Expo 86" (i.e. 23 years), and has become an integral part of the public transportation system in our "lower mainland" cities. One of its larger stations is located a 10 minute walk away from our house, so we walked and bought a day pass for all of us. At a total of $27, that turned out to be a bargain.



To begin with, we rode the skytrain to the Waterfront station, and then changed to the Seabus (a ferry service to North Vancouver, part of the public transportation system), to have lunch at Lonsdale Quay. The kids and my wife picked their traditional Chinese food; I don't particularly like Chinese food and ate a more traditional sandwich instead. Our older granddaughter also bought a new pair of shorts. We then returned via the Seabus to the Waterfront station, which is also the terminus of the new Canada Line subway.


The trains on that line consist of two cars (all pictures below are from the Translink web sites), connected by a "flexible" passthrough, much like subway trains in other parts of the world. The stations on the Canada line are just long enough to accommodate their combined length, so coupling two of these trains together would make them too long for the stations. The Canada Line train cars are wider than the Skytrain cars, making the cars incompatible with each other's stations. In fact, I don't know of any track connection between the two. That makes it necessary to have two different parts and maintenance centres. Personally I find this incompatibility illogical. I can understand that such incompatibilty might exist in some of the older cities in Europe, which started their electric subway services over one hundred years ago, but the skytrain line is still young (23 years), and the underlying remote-control technology cannot be that much different.

Another question I have is the use of only a single track into the airport itself - it means that only one train at a time can be at the airport station. I suppose that the underlying reason is the same as always - money, money, money. There was a big "Ahead-of-time, on-budget" statement from both our provincial government, and the public transit authority, made possible only by what I consider "corner-cutting"; even the underground track section which was originally meant to be a "bored" tunnel was actually built using the "cut-and-cover" method. That caused a great deal of financial losses to, and the closure of a number businesses along the Canada Line. Courtcases are still pending in that regard.



Notwithstanding all the above, the ride to and from Richmond and the airport is smooth, efficient, and will likely become popular with the commuting public and travelers from the airport to downtown. While most of the line is underground, the elevated and above-ground sections offer a grand view of Vancouver's spectacular scenery (that's true for the mostly elevated Skytrain too, of course).






The PNE (Pacific National Exhibition) is the granddaughters' perennial favourite. While the younger one is more interested in the rides at Playland, the older one is developing a taste for the agricultural and "arts-and-crafts" aspects. Our granddaughters' maternal grandparents (we're the paternal ones) are both wonderful and accomplished people and very artistic, and they really involve the granddaughters in that way when they are staying with them.

Both granddaughters enjoy the animals at the 4-H displays. As usual, we consumed the obligatory junk food offerings (corn dogs, mini doughnuts, hamburgers etc...).

An added feature this year was an open-air performance in honour of the Beatles - on their 45th anniversary. The theatre grounds were jammed with people. The band "Revolver" performed ably, and had the crowd highly motivated - everyone seemed happy. The amazing thing is that our granddaughters knew and sang along with all the songs; we ourselves, being of a generation well ahead of the Beatles, could not do that.

Marina (the older one) is also developing a talent for photography. She has a camera cellphone and took some interesting and artisic pictures: http://www.flickr.com/photos/thebigm/.

All-in-all we are having a great time with the two of them.
