This is Concepcion, a volcano,  forming part of an island (Ometepe)  in the middle of Lake Nicarauga. It was putting forth steam and smoke just as our plane flew over. There was a heavier cloud of material that you can just see on the other side of the volcano which was proceeding down the NW slope towards the small communities just seen on the margin of the island.  This sort of thing must be common, because right at this time the pilot announced that we were beginning our descent into San Jose, Costa Rica without even mentioning that there was an erupting volcano just below us!   The last eruption is said to have occurred last December with gas and ash rising 150 meters into the air.  Maybe the above photo doesn’t depict an eruption?  Hmm…looks like it goes at least 150 meters into the air.  Addendum:  I just found this site which I quote:

“On 8 March [just when we were passing over!] an ash and gas plume from Concepción rose to 2,100 metres altitude and light ashfall was reported in nearby communities. Low levels of seismic activity and occasional small explosions producing light ashfall were reported during subsequent days. On 12 March Washington VAAC issued a volcanic ash advisory reporting an eruption producing an ash cloud that reached FL100 (10,000 feet / 3,000 metres altitude). According to news reports there were two further explosions on 14 March. No casualties or damage resulted, although civil defence alerts remained in place for communities around the volcano. The Nicaraguan geological service INETER described the volcano on 19 March as ‘practically in a full eruptive phase’, with 34 explosions between 18:00 on 17 March and 11:45 on 18 March. On 19 March it was reported that the Nicaraguan government was sending army and navy units to the area around Concepción to strengthen civil defence preparations and prepare evacuation routes, ‘just in case’. The location of Concepción, on the island of Ometepe in Lake Nicaragua, makes floods and tsunamis a potential danger if the volcano were to erupt.

However, shortly afterwards activity at the volcano began to decline, with INETER reporting on 22 March that degassing and seismic activity had fallen to low levels in comparison with the preceding days. On 24 March INETER confirmed a ‘considerable reduction in activity’ but reported continuing ‘anomalous’ levels of seismicity. The current situation is that activity remains low, but the volcano continues to be carefully monitored.”

The northern end of Lake Managua in Nicaragua. Note the line of  steaming volcanoes.  Lake Managua is just to the north of Lake Nicaragua.

     I’ve never been on a tour before.  I’ve always looked down on them for some reason.  However,  I’ll be leaving tomorrow night to meet my father in Houston where we will fly down and tour Costa Rica.  Not like the Panama trip a few years ago when we made up our own itinerary and travel plans, but a conducted tour which provides all the meals, lodging and travel arrangments.  It looks like it will be lots of fun and I am looking forward to it.  I have always had a hankering to go to Costa Rica ever since I turned down a chance to spend a year in that country studying lizards–and getting paid doing it.

    I hope to be reporting on the trip, if not as I go, at least when I get back.

   My father returned home from the hospital today!  He had open heart surgery last Monday (Jan 25) which went very well.  I guess they said that he could have gone home yesterday (Friday), but he said he wasn’t ready to leave yet!  Four days seems like a very short stay after such major surgery, but I guess that is the norm now if the patient is doing well.  He was in ICU until Wednesday.  He is at my sister’s place where he will stay for about the next two weeks as he recovers.  I sincerely thank everybody for their prayers and good wishes.

     Needless to say I am very relieved and overjoyed that he is doing so well.  He has never had any sort of major illness, no surgery, and as a child, I can’t remember him ever being sick.   His experience which seemed to come out of the blue with no warning (good cholesterol levels, blood pressure about 120/70, etc) makes me much more determined to live the sort of lifestyle that precludes such problems–exercise, proper diet, etc.

     Last Thursday (Jan 21)  my father had some chest pain after returning from the store.  It wouldn’t go away,  and soon my father realized that this wasn’t the normal discomfort that he sometimes felt from the acid reflux which he sometimes has.  Then he did something out of character–he asked his next door neighbor to call an ambulance.

    I understand how out of character this was for him, because I am just like my father in many ways.  We both would tend to ignore pain until it became overwhelming, and for him to ask for an ambulance shows that it was something out of the ordinary.   I am still surprised that he did this and didn’t try to drive to the emergency room by himself.  It just goes to show that he was experiencing something out of the ordinary and that he is much smarter than I am.

     The next morning he had an angiogram and instead of a stent which they thought he might need, they found he had two coronary arteries which showed some blockage.  He would need double bypass surgery.  The interesting thing is that they found that his EKG was normal.  A slight elevation of heart enzymes showed that he had a mild heart attack also.

    My father will be 86 in March and has always been extremely healthy.  The doctor, one of the best in the Dallas area, said that he doesn’t consider the patient’s age in considerating this procedure, but their health, and that my father was otherwise in excellent health.

     The operation will take place at 7:15 am CST tomorrow.  I’d appreciate any kind thoughts or prayers sent my father’s way.

     Recently I was going through my chest-of-drawers in a long-delayed effort to clean them out.   As I sorted through some of the clothes I realized that my entire way of thinking about clothes has changed over the years.  I have always kept any clothes that I had until they literally fell apart or were outgrown.  After I reached adulthood, I would go for years without a size change, so I ended up with some very old clothes.

   I found to my chagrin and horror that there were clothes here that I acquired back in another era of my life.   Here was a t-shirt that I bought for a dollar in a street fair on Massachusetts street in Lawrence, Kansas back in 1972!  And here was a t-shirt that I had bought at about the same time that had the “ecology flag” emblazoned on the front.  I remember wearing that shirt on a Mammalogy field trip to Dodge City, Kansas in ’71.  In the back of the drawer I pulled out more relics of bygone times.

        One was a white undershirt with a picture of a duck riding a football and with the inscription “The Ducks Take to the Air” printed on it.  I remember somebody I knew who was leaving the University of Oregon in Eugene, Oregon in the summer of 1977 and was about to throw the shirt away and offered it to me.  I took it of course.   Here was a peculiar fuzzy sweater that I had received as a gift for Christmas in 1972.  And there in the back corner of the drawer was a t-shirt, stained with the smoke from an apartment fire that I had in ’81 which I remember buying in the summer of 1965!

    I gathered all these past mementos up preparatory to throwing them away or giving them to Good Will.  I put them into a gym bag which my grandparents had given me in 1962.  To this I added an old pillow which I had never liked which I had acquired for green stamps in the fall of 1967.  I sat there looking at the pitiful pile of stuff that I would never use again.  I busied myself with newer clothes that I never wore.  Afterwards I came back to the pile of old stuff.

    I put these all away again, telling myself that perhaps I would throw them out during the next cleaning.  For some reason the longer I possess something, the harder it is to get rid of it.  My New Years resolution is to get rid of new clothes— less than fifteen years old or so.

     It is Christmas Eve, 11:55 pm, and I am alone at work, getting ready to go out into the frosty night.  Once again I think back on past times with my family as I have many times before.  I haven’t posted much lately because I have been working so many long hours, but soon it will be all back to normal.  Merry Christmas to All!

      I was wondering why people were staring at me at the Mississippi visitor’s center last summer after I had pulled off Interstate 10.  I checked my zipper, nope…wiped my nose, nope nothing there, then I realized that I was wearing two pairs of glasses, one low down on my nose and the other right above it. 

       I have always had excellent eyesight, never needing glasses…until a few years back.  More than a few years actually.  Presbyopia is an ailment that inflicts many people as the lens of the eye looses its flexibility and can no longer accomodate close vision.   When this condition got to the point that I could ignore it no longer, I bought two expensive pairs of glasses.  “Over a hundred dollars for the frames?” I almost shouted in disbelief to the clerk.  “I can get a pair of sunglasses for a few dollars that has perfectly good frames!”

     “Oh no!,” she said, horrified, “these glasses are much finer, much lighter and stronger.”  So I ended up spending several hundred dollars for two pairs of glasses.  Years later I realize that…I was absolutely right, and was foolish to have bought such thin frames that snapped the first time any pressure was put upon them, and I never did get used to the bifocals.

     Now I get my glasses at a place that has satisfied my needs in many ways, and I have never had second thoughts about the glasses that I buy there—the Dollar Tree.  I buy glasses for close work for one dollar with a diopter value of about 2.5.  I also found that recently I have problems seeing far away–especially when driving at night, and I found that these one dollar glasses with a diopter of about 1.25 are great for seeing far away.  I even found some sunglasses with a diopter value of 1.25 which are great on sunny days.  These glasses work wonderfully well and are durable.  I have some that I’ve had for years, and I usually never have any problems with them unless I sit on them.

      So that day as I was driving down I-10 I was wearing my “far away glasses” (1.25) and doing perfectly fine until I needed to look down at the speedometer or something else on the dash board like the radio controls, and then I needed my “close up” (2.5) glasses.  Both were hanging about my neck by cords, and I found that by placing the close up glasses low on my nose and my far away glasses up higher on my nose, I could switch back and forth with no problems.  However, I had neglected to pull one off my nose when I went into the visitor’s center.  

        I found that method works very well, but I haven’t quite overcome the attention I get when I do it, so I usually only do it at home.  However, I have left the diopter labels on the lenses in order to tell the glasses apart, and I always get comments such as:  “You still have the label on your glasses.”  “I know,” I reply,  “And I still have the label on this one,” pointing to the other one hanging about my neck.

When I reached the beach on my walk two Sundays ago, I saw a large black body out in the water, then a great fin protruding above the surface.  At first I was confused as to what I was seeing,  then everything clicked into place, and I realized that I was watching a pod of Orca or Killer Whales coursing north through the narrows of Puget Sound.  I immediately began shouting with excitement.  Not only was this the first time that I had ever seen these magnificent creatures, but they are rarely seen this far south in the sound.  They had just passed the park which I was in and were taking their time on their way north, their backs and fins protruding above the water.  I stood there watching them until they disappeared.  Then I realized that I had been the only one shouting, but I felt blessed and full of energy.

The Killer Whale got its name from the fact that it often was observed eating whales, but there are at least three different groups or Orcas which seem to have specialized in either fish and squid eating, and those which eat almost exclusively marine mammals.  I was tremendously excited after seeing the Orcas pass, and while musing on them I was curiously reminded of the end of the universe.

I was reminded of the death of the universe by the fact that Killer Whales occupy the top of their food chain, and thus their numbers and biomass are severely limited by the Second Law of Thermodynamics which basically says that energy tends to go from ordered states to disordered states, and during any transfer of energy some energy is lost to the system (converted to heat).  Thus every time a cow eats its supper (plants) roughly 90% of the energy in the plants is converted to heat and lost to the system (ecosystem in this case).  So consider the following marine food chain scenario:

phytoplankton (100%)—->zooplankton(10%)—->small fish(1%)—->larger fish(.1%)—->seals(.01%)—–>Killer Whales(.001%)

Suppose the phytoplankton by means of photosynthesis captures a certain amount of energy from the sun.  We’ll say this amount of energy is 100%.  This represents what we start out with in this food chain.  The zooplankton (small floating animals) eat the phytoplankton, but about 90% of the available energy is lost, so the zooplankton only ends up with 10% of what we started with.  Then the small fish eat the zooplankton and the same thing happens, 90% is lost and the small fish end up with 1% of the original amount.  And so on…until we end up with the Killer Whales which in this example will end up with only 1/100,000 of what we started with–all due primarily to the Second Law of Thermodynamics!   Not much energy is available to the top predators in food chains.

Or consider this alternate food chain:

phytoplankton (100%)—->zooplankton(10%)—->Great Blue Whales (1%)

The Great Blue Whales by eating much lower on the food chain (zooplankton: krill mostly), theoretically has 1% of the energy with which we started–a thousand times more potential energy than is available for the Killer Whales!  So theoretically the biomass of Great Blue Whales could be as much as the total biomass for the small fish in the first food chain…just concentrated in much bigger bodies, potentially much more biomass than in the Killer whales.  Two strategies exist in this case:  by eating at this level in this food chain, you can be small and extremely numerous or large and much less numerous–the biomass should be about the same.  I think there is a lesson here as the human population density soars above 6 billion people.  Can we continue to eat high on the food chain?

So why did all this make me ponder the end of the universe?  Because if energy continues to go from concentrated sources of energy to less concentrated sources (entropy), then eventually the universe will run down.  All the stars  and other energy systems will have dissipated their energy into heat, there will be no more people, spiders, planets, stars…nothing but a universe in which the energy is evenly distributed–the Heat Death of the Universe.

I was reading the paper today, and when I got to the funny papers (comics), I found an odd thing.  I kept seeing the same references to volunteerism and community service in many of the strips.  Below is a summary of what I found:

1. Garfield: “Today I volunteered to help clean up the city park.”
2. The Born Loser: girl volunteered to rake leaves for the born loser who had hurt his arm.
3. Stone Soup: woman building houses for charity in Thailand.  (I hate this strip and never read it…did this time for the survey).
4. Pickles: The old lady volunteered to read to schoolchildren.
5. Luann: A service “team” started at high school “Woohoo! Volunteers rule!”
6. Baby Blues: Children volunteered for too many projects.  “Ok, I got everything straightened out with your service coach.”
7. Pooch Cafe: Pooch volunteered to visit sick kid in hospital.
8. Dennis the Menace.  Dennis volunteered to wash the Wilson’s windows.  Sign read: “Volunteer to help others.”
9. Blondie:  Dagwood volunteered to help with a senior citizens’ project.
10. The Family Circus:  Kids helping out in the kitchen.  “Hi, Mommy!  Can I volunteer to be some ‘nother help?”
11. Marmuduke: He starts a homeless shelter for dogs in the house.

Eleven out of 22 comic strips dealt with volunteerism–50%!  “Ok,” I thought, “obviously it must be Volunteer Week or something like that.”  But no,  Volunteer Week was April 19-25.  What the heck is going on?  It must be something that has been in the news or perhaps being pushed by somebody…but for the life of me I have no idea what.  I have noticed this happening before–the comics suddenly dealing with a particular subject.

Ok, I just googled some more and may have found what is going on: “18 October: The media blitz has arrived.  As we reported, in June, the Entertainment Industry Foundation (EIF) announced a commitment to incorporate volunteering and service into both news programming and ongoing fictional television series beginning the week of October 19.   EIF has branded this effort as “iParticipate” and opened a Web site at www.iparticipate.org.  There you can learn about the initiative, keep up with a blog about it, and view video clips of celebrities answering the question, “how do you serve?”” http://www.energizeinc.com/news.html

Ok…it’s some sort of media blitz by the Entertainment Industry Foundation.  I guess it even involves the funny papers.  How does this work?  Do the comic strip writers receive their subject du jour from somebody, and they dutifully accomodate their strips to  promulgate the subject?

Why am I not thrilled?   Volunteerism is a good cause isn’t it?  And the media has been influencing us for years to buy products, etc.  Brainwashing for a good cause is good isn’t it?  Why does this leave a bad taste in my mouth?  (making mental note of those strips who participated and those who didn’t)
