On a map the distance between Puerto Viejo and Monte Verde looks to be about 50 miles. If not for the pesky mountains between the two, it would not have taken six hours of driving to make the journey. Had I opted to go by way of San Jose, it would have been faster, but I wanted to visit the Arenal volcano and lake along the way.  Two hours of normal driving, two hours of continuous winding roads and two hours of bumpy dirt roads through a torrential downpour made for an exhausting travel day.  Fortunately, my day started with an exceptionally productive nature walk at La Selva and a very enjoyable visit to the Costa Rican Nature Pavilion in La Virgen.

La Selva Biological Station is a protected area encompassing 4000 acres of low-land tropical rain forest in northeastern Costa Rica. It is estimated that it contains over 500,000 species of mammals, birds, and insects. Owned and operated by the Organization for Tropical Studies, a consortium of universities and research institutions from the United States, Costa Rica, and Puerto Rico, it is recognized internationally as one of the most productive field stations in the world for tropical forest research and peer-reviewed publications, La Selva hosts approximately 300 scientists and 100 university courses every year. Guests are also welcomed and can mingle with researchers while staying at the facilities. 

Not surprisingly for the rain forest it rained for much of the day. Fortunately, not before I took a 3 hour walking tour with one of the resident nature guides early in the morning. He spotted wildlife I would have walked right past and provided great information about the ecosystem. Ninety percent of my photos for this day were lost with my cameras.

 

The last time I visited the Poas Volcano (family Christmas vacation several years ago) it was shrouded in clouds.  This morning I arrived at the park the moment it opened and was rewarded for the effort with clear skies and a magnificent view of the steaming crater. As you will learn in a subsequent post, two of my three cameras were stolen and with them many photos from my first two days including some magnificent wide angle shots of the volcano. Fortunately, I still have a few telephoto shots taken with my third camera.

As the clouds started to roll over the mountains, I made a beeline for the La Pas Waterfall Garden successfully beating the tourist buses coming from San Jose.  In addition to the magnificent falls (all photos lost), I was overwhelmed with the wildlife to be found in sanctuaries throughout the park. Thankfully, I did not lose my frog photos which were among my favorites of the visit. The frogs are contained in a large sanctuary in which they are free to roam.  For a small tip the frog minder was happy to show me where each of the species could be found.

The variety of bird species which can be found in Costa Rica is amazing.  Here is but a small sample from day one.

I lost all of my butterfly photos (hundreds) except for these two.

My destination for the evening was the La Selva BIological Research Station.  I drove like a full blooded Costa Rican, which is to say, insanely fast, so that I would arrive before the 5pm registration cutoff.  I stopped only to photograph a group of white nose coati that were foraging by the side of the road.

I arrived at La Selva just in time and dined with visiting students and resident researchers before going out on a solo night walk in the rain forest.  Other than being very scary, I was assured by the experts that there were really only two dangers to be concerned about, poisonous snakes and bullet ants.  Staying on the path and keeping it illuminated with a flashlight solves for snakes and not touching anything or sitting down solves for ants. Had I chickened out, I would have missed these photos of a two-toed sloth and her baby taken by the illumination of my flashlight.

I am traveling today and received the following note from Maya.

Papa,

I haven’t been taking many pictures with my camera, but here is a screen shot of my desktop as I work on making histograms. I have squeezed all of the applications that I usually have running (minus TBrowser) to make a histogram all onto one page. Usually I work across a couple of desktops much more spread out, but I thought this would make an interesting picture. The bottom left is just your average Linux terminal where I have asked the computer to open a file in the ROOT program. When I am actually working on and changing the histogram, I use this terminal all the time to resubmit my request which renders the updated version of the graph. The right side of the screen is an Aquamacs text editor window (a lot like Vim, but it uses color coding to keep things organized). I wrote all of the code in that window. It’s relatively simple, but when I arrived I didn’t even know how to declare a pointer, or even what a pointer was, or that my computer had a terminal on it… so I’ve come a long way. When I ask my terminal to open the histogram file, the aquamacs is what it reads for instruction. The top left visual is the product of all the hectic syntax everywhere else. It’s cool how the rather ugly C++ ends up making something so aesthetically pleasing.
Today, I will be adding more commands to my code so that 1) it will have title text 2) the like sign data (blue) will be fit with a 3rd order polynomial function and 3) the unlike sign data (red) will be fit with a gaussian function, hopefully. The last one will probably be the hardest, because I only just learned about Gaussian fits yesterday. Also, side note, the x axis of the graph is being measured in volts, not grams. Giga-electron Volts actually, GeV.
I’d say I understand about 70% of the project I am working on. Yesterday I spent a lot of time reading about the Muon Telescope Detector, which is the detector that collected this upsilon data. I’ll include pictures of its general construction. I’ve also been reading and asking about upsilon. Upsilon is a meson that is made up of a bottom quark and its antiparticle. Because the bottom quark and the bottom anti-quark have color charges that are compliments, they cancel each other out. This means that upsilon is “flavorless” or in a quarkonium state. I have yet to figure out what is significant about this state or why we are so interested in it, but I’m not done reading yet and I can ask more in tomorrow’s meeting.
Eric, the other intern in my lab, has also been looking at a flavorless meson emitted in the central collisions. It’s called J/psi (pronounced jape-sigh). It’s really similar to upsilon in that it is comprised of a quark and its antiparticle (compliment color charges that cancel each other out). I only mention this because Papa you will be psyched. Charm + anti-charm = J/psi meson. According to wikipedia “Mesons formed by a bound state of a charm quark and a charm anti-quark are generally known as ‘charmonium’”. I feel like charmonium is a Carl word.
So, long story short. The histogram I just made is comparing the number of like sign and unlike sign upsilon mesons that were emitted over the course of many RHIC collisions from their last batch. The unlike signs are slightly more common which is very important!! I don’t know why, but Rongrong says it is! Anyways, blog message received, you may post any or all of these pictures.

I spent part of the morning and afternoon at this house in Lynn helping our close friend Aliza with some simple furniture assembly and computer configuration.  Her son, Win, has taken up residency here after his recent graduation from the Perkins School for the Blind.

I leave for Costa Rica tomorrow where I will be traveling  for the remainder of the month before continuing on to Iceland through August 8.  I hope to return with a treasure trove of photos and ask for your patience until then.

A new anthem for grit.  I only wish that Amputee Soccer was a sport sanctioned by the Paralympics.

We caught up with Maya this weekend and learned about the first week of her internship at Brookhaven National Labs.  She has had to work very hard to familiarize herself with many of the concepts she will be dealing with and to teach herself C++ programming which she needs for her work project. Her task will be to take data gathered from the high-energy collider and generate histograms of the types of particles emitted during collisions.  She is reluctant to ask too many questions given how valuable the time of her mentors is but is finding help from some of the returning interns.  She has sent no pictures yet (hint), so I have gone to the archives for a photo of her taken exactly ten years ago.

The Tiny Home movement advocates for living simply in small homes. One variation includes tiny homes on wheels (a more permanent alternative to the traditional travel trailer). While we will not downsize to this level, our next home is going to be substantially smaller than our current one, perhaps one fifth the size.  This afternoon Jeanine and I attended a Tiny Home show on the grounds of the Emerson Umbrella and listened to life style converts describe their experiences. Less is often more, a lesson we are slowly learning.

Our home in Indianapolis (above-side view) was twice the size of our current home in Concord so we are already moving in the right direction.

Photographing swallows in flight is quite a challenge. Not only do they move with great speed, they change directions constantly and are very hard to follow with a long lens.  With some practice this morning, however, I was able to get a few images that were not terrible.

Jeanine and I rode our bikes to the Hapgood Wright Town Forest this morning where I was hoping to find this patch of mushrooms.  I had seen a Facebook picture of them and thought I would enjoy tracking them down for my own photograph. On close inspection, I discovered they  were made of ceramic and later learned they were part of the 2016 Art Ramble outdoor art installation.

Amanitus (2016) 
Glazed ceramic, various pieces each 6’ X 3’

Artist Statement: The strength of artwork, Amanitus is rooted in contradictions. Physically, these bright, colorfull mushrooms grab our attention as they contrast with the greens and browns of their surroundings. Contextually, the mushrooms (based on the species amanita muscaria) speak more of fantasy rather than natural reality. Cultural depictions of these toadstools revolve around images of gnomes and fairies, images appearing in traditional fairytales and classics, such as, Alice in Wonderland and Disney’s Fantasia. The mushrooms appear almost as candy, yet in reality they are listed as poisonous. Amanitus is a group effort! The ceramic mushrooms were created by many; the artist, his family, as well as, students and residents of Concord. Many of the mushrooms have the initials of their creators carved into the base of the mushroom.

 

Ever since Nicolai started using crutches (at 5 years of age), Jeanine has been saving the right pant legs that were removed when tailoring trousers for his body.  She did so with the idea of one day making a quilt from them.  Time for the project never seemed to materialize. Finally, she found and worked with a quilt maker who completed the design and fabrication.  This afternoon we presented the finished work to Nico with the understanding that we would gift it to him when he graduates from college.

The act of cutting all those pant legs off was never easy for us; a stark manifestation of loss.  The quilt represents just the opposite;  a reminder of the beauty and warmth that we feel when we admire our amazing son.

I have refined my hummingbird photography technique sufficiently to feel prepared for my trip to Costa Rica next week.  I plan to do a week of hiking and birding before connecting with Nicolai who is competing in an international amputee soccer tournament in San Jose at the end of the month.  When I return from Costa Rica I will have 4 hours in Boston before boarding a flight to Iceland where I will compete in a soccer tournament with my over-50 team from Concord.  Packing for two trips in very different climates has proved something of a challenge but as of today I think I am pretty well set.

Early morning walks in the backyard have been proving quite interesting lately.  Once the morning dew has evaporated, however, so too have many of the photographic opportunities.  Maya reported that her first day at Brookhaven National Labs went very well.  The researcher she will be working with is studying the quark gluon plasma. She still does not know exactly how she will be assisting her in that endeavor but will probably find out tomorrow.

Spotted this little fellow at the hummingbird feeder this morning.  I have been too lazy to setup a high speed flash to really freeze the wing beats but will try and get one really good in-flight photo before I head off to Costa Rica where I hope to find many more such shooting opportunities. The practice should help me come back with some really nice shots.
