On immigration (2/22/2016)

It is election season.  Great, the demagogues are out, throwing all kinds of words at each other, you name it.  Don’t worry; I am not going to try to convince you to vote for one or the other.  I just find it fascinating, sometimes to the frustration of my wife.  But then I am one of those immigrants that are being bantered around, albeit a legal one and a Caucasian one (below I’ll write more about an interesting thing that always happened to me as a foreigner in southern New Mexico). Where I come from, the primary system and big money politics is alien on it own, so yes this is fascinating.

The symbol of our great country, the bald eagle.  I took this photo in Yorktown on 2/21/2016 during our morning walk with the dogs.  A man came to talk to us basically indicating how proud he was seeing it and how he wished he could watch it hunt and catch its prey.  The only thing I could think was "bald eagles are somewhat cowardly and go for the infirm individuals and dead animals (carrion), if you want to see a real hunter, watch an osprey." But I did not dare to tell him that, because they are real stately, beautiful birds, well worth their magnificent status, and I did not want to burst his bubble.
When I became U.S. citizen on September 9, 1994 I did it for a number of reasons:
  • My wife and daughter were U.S. citizens;
  • My wife and I had been married 17 years and our daughter was almost 6, we did not think we would be moving back to Europe anytime soon;
  • I had lived here permanently for more than 8 years and had my green card since 1980 (14 years);
  • My Masters and Ph.D. degree were both from U.S. institutions and I interviewed once for a job in Holland in 1990 and I noticed that I did not have command of the Dutch scientific jargon in my field and the persons interviewing me let me know that;
  • In a past international job, a few frustrated Dutchmen had tried to do everything in their power to show me that their European education was better than my U.S. education (you traitor);
  • Therefore, I had come to the conclusion that I was going to remain in the U.S. for the rest of my career;
  • In 1993, I was rejected for the ideal job at the last minute, when at the time of contract signing, I was asked the question: “are you a U.S. citizen”; this was for the job as manager of natural resources division at the Nevada Test Site; and lastly
  • I decided, if I want to stay in the U.S., I should be able to vote and be a responsible citizen.
Truthfully, I have not missed an election since I turned a U.S. citizen, although there have been elections where I have voted with my nose pinched very close!  I strongly feel that I am not allowed to complain if I don't vote!

So what happened to me in New Mexico?  I got my Ph.D. at New Mexico State University in Las Cruces.  I stayed on after my Ph.D. to do a post-doctoral study, and that is where this story is from.  Las Cruces is in southern New Mexico, very close to the border with Mexico.  There is no wall there between the U.S. and Mexico, and I am not even sure if there was a fence at places when we lived there.  If there was a fence, there were probably holes in it.  There were roadblocks at various locations on the highway where border patrol agents stopped your car and searched your vehicle for illegal aliens.

At the time, I was doing research in the mountains above Alamogordo, New Mexico and had to drive through the White Sands Missile Range to get there.  I traveled that road at least twice a week for an entire summer, usually in a state van or truck with two Mexican-American technicians.  These guys were American citizens, one born and raised in Las Cruces, the other near Albuquerque.  There is such a border patrol roadblock on that part of the highway, and yes we got stopped every time.  Guess what?  Without failure, my two technicians were asked every time for identification and proof that they were legal residents of the U.S., and I, who was the only (legal) alien or immigrant in the car was never questioned or asked for identification.  Thank goodness my two companions took it very lightly and it became a standing joke, but it always amazed and somewhat upset me.  It undeniably was a form of racial profiling.

While these guys put on a big smile and took it all in stride, I wonder.  I can imagine that privately they felt hurt, humiliated.  I can understand why someone (some ethnic groups) would vote for certain political candidates or not, based on some of the rhetoric being spouted about certain races, certain under current or things not being said.  As an immigrant or alien, I am fascinated with U.S. politics and probably hypersensitive to some of these things as well.  I will keep watching and listening and making my own opinion about it all.  But one thing is for sure, I will vote!

Water (2/12/2016)

Walking in the woods this morning after a very cold morning I was reminded of one of the things I really try to push in my classes: 

“The importance of (clean) water!”

I tell my students that life is not possible without water and that one of the reasons is that water has these special properties.  One of these properties is that is expands when is gets colder than approximately 40 degrees Fahrenheit.  Below that temperature water becomes more buoyant (lighter) because of the expansion and rises to the top of the water column.  When temperatures drop below freezing water freezes on top and creates this insulated layer which allows fish and aquatic life to survive in lakes, ponds, rivers and oceans (and it allows my crazy Dutch country men and women to win gold medals in speed skating).  If water would freeze from the bottom up these water bodies would be lifeless because every thing wold freeze to death.  This is also one reason why NASA is so fascinated by the (water) moons of Jupiter and Saturn, because they are expected to have liquid water deep down.  There may be life up there!

After an night of frost you can see the small cracks that formed and refroze as a result of the expanding ice, creating this magnificent mosaic.

The photograph above gives a great example of it all.  There is liquid water under the ice.  Obviously after the water froze it got even colder and the expanding ice has all kinds of small cracks in it from expanding and now looks like a mosaic.  Really cool!  Although it may be quite disturbing that instead of enjoying nature, I am constantly analyzing things in nature, just like that cartoon that I saw on Facebook of how a scientist spends his vacation on a tropical island.

Anyway, I do teach almost daily about the importance of water, about the importance of clean water and about keeping it clean through erosion and sediment control and stormwater management.


Expanding ice in wet soil causes what we call frost heaving.  These soil particles become very loose and can become erodible and end up in our stormwater.

What can you contribute to keeping our water clean?
  1. Pick up your animal’s waste, especially when they do it on the road or in or near a place where it will readily enter the stormwater
  2. Don't over-fertilize or apply too much pesticide to your yard
  3. When you apply fertilizer or pesticide stay a few yards away from streets or your property boundary
  4. When you wash your car do it on the lawn not on a paved surface, like your driveway or the road in front of your home.  Better, do it at a car wash.
  5. Don’t poor waste oil or any other wastes down the storm drain
  6. Minimize the bare soil in our yards and mulch
We all can contribute to clean water, and it is so important!  If we run out of water, our earth will turn into something like Mars, lifeless; without clean water who knows, but it will not be pretty.  As I teach my students:

"Filthy water cannot be washed!"


The big ephemeral pond behind our home has the same mosaic like features.  The water in these ponds is so nice and clean.

Roots (2/8/2016)

When I took the photo below of the root my wife told me that it would make a great entry in my next nature blog/journal.  Her comment did not leave the back of my mind for a long time now; it has been more than a week since I took this picture.  It is like planting a seed in one’s mind and watching it germinate and take root (pardon the pun).

This picture was taken in Newport News Park showing an old road cut and how the tree is rooted into the soil (photo take 1/31/2016).

I was at a loss what to write about, except for showing this picture, but then while listening to a program on Post Traumatic Stress Disorder or PTSD on Satellite Radio it all the sudden struck me: what we are now is all rooted on past experiences and we feed on it, whether we like it or not.  Buddha tells us:

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment,” 

but it is so damn hard to follow.  If you are like me, it is so difficult to live in the moment sometimes, my mind is all over the place.  (So sorry guys no nature blog while talking about roots)

Listening to that program on PTSD, reminds me of a dear friend who served in Iraq and suffers from PTSD.  I witnessed one of his flashbacks and it was terrible to see a strong grown man have these.  Another acquaintance of mine who served in Afghanistan told me he has them too.  Their current lives are rooted in those past experiences, it has changed them and it’s difficult to escape at times.  My father had them his entire life, after spending time in Hitler's camps.  Interestingly, the doctors were discussing that there are indications that they can now detect PTSD in the tone of voice of PTSD sufferers and maybe even in the content of their saliva. 

Listening to the program, I was immediately taken back to my first experiences in Uganda in 1978, and I was wondering if I am (or my wife and I are) psychologically shaped the way I am (we are) by the events I (we) went through back then, just like the doctors were discussing on the radio.  I know my wife and I had PTSD after we were liberated in May 1979; the strange sound of a toilet flushing sent my wife under the table the first time she heard it, thinking we were being bombed or being shot at.

But even now, just listening to the discussion on the radio gave me flashbacks to that time 37 and 38 years ago.  Suffice it to say, I should have been killed but I escaped getting killed probably four times.  I also still feel guilty for not preventing a young boy from getting killed by an angry mob two days after we arrived in the country.  It’s all too gruesome to describe, but if you like me to, let me know and I can blog about it, one day.

It all came rushing back to me, again.  I wonder if the tone of my voice and my saliva are different from what it would have been if I had not experienced it, or my elevated blood pressure is caused by it or my migraines are partially the result of it.  So yes, I am rooted in the past, and I know I should not dwell on it just as Buddha says, but concentrate on the present and maybe prepare for the future.

Downtown Richmond, the roots of this old tree have expanded so much that they are growing over the curb and the sidewalk.  It makes you wonder what they can find there.  I am always amazed by the tenacity of some of these trees.  Looks like someone is trying to feed the tree some Red Bull, I hate people who liter (photo taken 2/9/2016).
