Return what you borrowed

A month ago today, our son Derek died. His ashes will be dispersed in a couple of places on Earth which he considered to be some of the most beautiful.

We are all made of "star stuff"- the original hydrogen, and most of the other atoms generated eons ago in some stupendous explosion of a supernova. Our existence may be considered to be an assembly of these various atoms into the molecules which constitute you, me, Earth, and all the animals and things that surround us. When we die, these are all returned to some place in this universe - perhaps to become part of some other intelligent entity eons from now.

It is possible to say, then, that we only "borrow" the building blocks of which we are made. Derek's molecules are therefore in the process of being returned to where they came from. This resonates with me.

As some of you know, I've had a life-long interest in astronomy. New stars, nebulae, and planets are constantly being formed somewhere in the universe. One of those places is the Orion Nebula, pictured above. From now on, I'll forever look at the heavens with the thought in my mind that some of these future objects will incorporate some of the same atoms and molecules which were once a part of Derek.

We'll all return what we borrowed.

The New Normal

The last 3 weeks have been ones of upheaval in our family, but the new reality is taking hold.

Most of you who read this blog may be aware that Derek's last post generated an unprecedented amount of traffic on his website (over 10 million hits), and a large number of comments. Additionally, local and international media picked up the story. We have been in interviews on radio and TV; had one family memorial and one public memorial for Derek, also covered by TV.

That's more or less in the past - which is just as well; there are fewer reminders of Derek's death.

For us, as his parents, our grandchildren, and our daughter-in-law, as well as our extended family, there will be no forgetting, of course. However, life carries on. Our daughter-in-law and granddaughters are in Seattle for the long weekend, along with a good friend. We are at home, looking after Lucy, their little dog. We are fortunate that we live in the same duplex, so Lucy can go to her own home for a few hours every day.

Our family routines are changing; this is the new normal.

The end of the gravel road

Our son Derek died in the evening of May 3, 2011. He had to deal with metastatic colon cancer for four and a half years. Our family is immensely saddened, and his death will leave a large void among us. He will be deeply missed by all of us.

Derek had an extremely unique intelligence, and a multitude of interests. All his friends, and we, could ask him almost any question and he would have an intelligent and easily understood answer. His blog http://www.penmachine.com is a testament to his extensive knowledge and eclectic thinking. Through his blog, he a affected a multitude of people, and many commented on how his posts had helped them deal with adversities of their own. He was a very knowledgeable technologist - he had extensive knowledge in computer and internet technology, photography, was a musician and composer, had a degree in marine biology, and a diploma in writing (both from UBC). Writing was his passion.

Both the Province and the Vancouver Sun published articles about him today. Here is what Pete McMartin of the Vancouver Sun had to say:

No medical treatment, including several operations and many sometimes very debilitating chemotherapy treatments could stop this cancer. Throughout these years he maintained his interests and wrote about them in his blog. It never became a "cancer blog".

As his parents, we have lost our only child - a part of us died with him. We are lucky to have his wife and our two granddaughters living next to us. For us, Derek lives on in them.

A memorable Easter

We had our Easter family dinner at our house yesterday. My wife Hilkka cooked her specialties, and other members of our extended family brought their special food as well. Derek's and Airdrie's friend Steven, and Derek's on-line friend Jean-Hugues took part. Jean-Hugues connected with Derek when both were diagnosed with colon cancer at about the same time; he came all the way from Paris, France. Thank you, Jean-Hugues. You, Laurence, and your family paid us all a great honour.  


For us, this dinner get-together was bitter-sweet: it likely was Derek's last family dinner. He managed to stay for around two hours, then he had to go and rest. Fortunately, he can still enjoy the taste of food. I think that he inherited his wide-ranging tastes from his mother.


We're lucky to have Derek, Airdrie, and our granddaughters Marina and Lauren adjacent to us - our porches connect - so it is easy to go back and forth.


This was not a maudlin occasion. Lively conversation is always part of our family get-togethers and this one was no different in that regard. Although Derek's voice has still not come back, he can "rasp" clearly enough to make his points. His mind is as incisive as ever.


Here are some casual pictures I took:

We hope that you all had an enjoyable Easter.

A little cheer on a dreary day

As many of you know, I'm interested in Astronomy. Accordingly, above is a picture of a "Stargazer Lily" http://en.wikipedia.org/wiki/Lilium_%22Stargazer%22, of which we have some sitting in a vase on our living room table. Notice the "liquid sugar" on the stem to lure insects, I would think. That's probably what gives these flowers their heavily sweet odour, which seems to be particularly noticeable in the evenings. Click on the picture for a larger image.

Below is a picture of the camelia "bush" in our neighbours' back yard - these blossoms were not there yesterday. Click on the image.

This has been a rather unpleasant week, and not just because of the weather. Derek has not been feeling well, and yesterday we received notice that a very good friend of ours, Al, had died. We've known Al and Ernie, his lifelong partner (over 55 years), for more than 25 years. Al was almost 85 years old, and he had not been in shape for the last four years. A sad day for all of us who knew Al.

I posted these pictures to show that there is always something beautiful in nature. A little cheer on a dreary day...

All talk-little action

Last night, "Earth Hour" passed with nary a difference in our neighbourhood. We put out all lights in our house, turned off the TV and computers, lit up some candles, and had a glass of wine. Before the earth hour we had watched an episode of the "Cosmos" (Derek gave us the CD series for Christmas), and discussed the subject of that episode ("Backbone of the Night") while the lights were out.

Occasionally, I looked out of our front window to see whether other people had turned off any lights - nobody else seemed to have done so. Windows were still lit, outdoor lights were on, and the clouds were as bright as ever from the stray city lights.

For all the talk about preserving the environment, cutting energy consumption, making a smaller "footprint" on our planet, our neighbourhood at least gets a failing grade in that regard from me.

The solar flare of Monday, Feb 14

Near the centre of the image is the white flare which sent a massive amount of energy to Earth a couple of days ago.

I looked at the Sun through my Hα telescope yesterday but the flare is not visible in Hα light; however, the disturbed area where it originated on the Sun is. In particular, the "striations" at the centre of this image are visible in Hα.

Caution: Never look at the Sun with the naked eye! All events on the Sun must be viewed through special protective filters; these reduce the light to about one thousandth of one percent (=1/100,000).

Here's a pertinent article published by National Geographic Magazine:

Published February 16, 2011

The most powerful solar flare in four years exploded over the sun late Monday, according to NASA.

The magnetic instability that caused the flare also unleashed a blast of charged particles that should hit Earth's atmosphere tonight, possibly sparking auroras farther south than usual, experts say.

(Video: Solar Flare Causes "Sunquakes.")

The most powerful explosions in the solar system, solar flares occur when magnetic field lines on the sun cross, cancel each other out, then reconnect.

These "explosive reconnections" release huge amounts energy as heat—in this case, a short blast measuring roughly 35 million degrees Fahrenheit (19 million degrees Celsius), according to physicist Dean Pesnell, project scientist forNASA's Solar Dynamics Observatory, or SDO.

In visible light, only the small dark surface blotches of sunspot 1158, which spawned the flare, could be seen. Without the SDO satellite, "you would never have known what was happening above" the sunspot, Pesnell said.

But the satellite's ability to detect many wavelengths of light allowed the observatory to image not only the flash, in extreme ultraviolet, but also streams of charged gas arcing along magnetic field lines—a "perfect example of solar physics." (See a January picture of a large solar flare.)

Not that SDO is perfect. Its digital-imaging hardware, for example, was overwhelmed by the intensity of the flare, resulting in overexposed areas that make the flare look bigger than it was.

Imaged flawlessly, the flare, at its most intense, would "look like a ball of light floating above the surface," Pesnell said, "about the size of a house."

(See pictures of solar eruptions.)

Solar Flare Plus Aurora-Inducing "Wind"?

Monday's fleeting magnetic breakdown also sent "a firehouse of material spraying out from the sun" when "spring loaded" streams of charged gases were freed from the magnetic fields that hold them in place on the sun.

Such so-called coronal mass ejections can pose radiation threats to astronauts and overwhelm Earth's magnetic field, potentially disrupting satellite communications and power grids on the ground.

But the solar gale now heading our way isn't expected to be particularly harmful. That's because, according to predictions, "it won't hit us dead-on," Pesnell said.

Still, he said, strong geomagnetic activity is expected Wednesday night, perhaps most visibly in the form of auroras—the southern and northern lights, which occur when atoms above Earth's gain energy from solar charged particles, then release it as light.

The U.S. Space Weather Prediction Center, he said, forecasts a 30 percent chance of auroras as far south as Washington, D.C.

Stargazers below the northern U.S. should look for a diffuse reddish glow, however, rather than the neon-hued "curtains" seen around the Poles. Furthermore, the nearly full moon will effectively dim any auroras Wednesday night.

X-Rated Solar Flare

Monday's blast was the first X-level solar flare since December 2006—X being the highest level of the flare-rating system.

But at X2.2—or 0.00022 watts per square meter—the Valentine's Day flare wasn't unexpectedly powerful.

"It fits in just perfect" with forecasts that show the sun entering a period of increased activity, Pesnell said.

The recent explosion, he added, has nothing on the giant blasts of the early 2000s. That most recent active period spawned the biggest solar flare on ever directly measured in November 2003—a blast more than ten times as powerful as Monday's.

Compared to that "big honker," he said, this week's flare "is pretty typical—except it was beautifully typical, because we saw it with SDO."
