The Do’s and Don’ts of Tri-State

Do wash your hands between caring for each bird because many of Tri-State’s patients are infected with contagious diseases such as Giardia or Finch Eye. Don’t put food in a Red-Tail Hawk’s cage without using tongs since they are food aggressive and will fly at you to take the food directly out of your hand. Do reuse food if the bird doesn’t eat all of it overnight because at a non-profit organization saving food=saving valuable money. Don’t forget to hangup the hoses when not in use as the water in them may freeze and make them difficult to use the next the day.

These are just a few of the many important do’s and don’ts I have learned in my first four days volunteering at Tri-State. However, each day I am asking fewer and fewer questions and I seem to be falling into a daily routine. I arrive at 8 in the morning, get briefed on the birds in house at the volunteer meeting, work outside and take care of the birds for however long that takes, and then do any tasks the supervisor of the day needs done until 3, which is when the PM bird feeding begins. In a normal day, I probably care for about five birds or so by myself and then work with other volunteers to take care of the cages containing more than one bird. Currently, there are around 30 birds in house including three Bald Eagles and eight Red-Tailed Hawks. Below is a picture of a Red-Tailed Hawk.

Watching birds like these hawks soar in the flight cages to build-up muscle strength in their wings again has been incredible so far. The chance to not only get up close and personal with these birds, but to actually assist in their recovery by putting medicine in their food and such, has been one I won’t forget. Although cutting open a dead mouse’s stomach and filling it with medicine isn’t most peoples idea of fun or interesting, there is something serene for me in this “gross” action. I find peace in the fact that my volunteer work is helping to save the birds at Tri-States lives, and I am eagerly looking forward to continuing my work throughout the next week and a half.

They’re Hanging WHAT from a Balloon?

Telescopes that search the skies for wavelengths that are too delicate to pass through our atmosphere have to be hoisted up into the air with a giant balloon. The telescopes are mainly made out of metal, so to keep one airborne, balloons the size of football stadiums or bigger are needed. You heard that right: not a football field — a football stadium. BLAST is a telescope I worked with today which will use this balloon mechanism when it observes the universe around us. Today I met with two students who are building the telescope, complete with reaction wheels and motors to allow the telescope to turn and state of the art optics mechanisms to filter light. The frame is about the size of a minivan, and is made of white metal pipes which will hold a larger metal frame, a carbon fiber mirror, and a gigantic cryostat filled with liquid helium, cooled down to below its boiling point near absolute zero. Nate, a graduate student, explained the mechanisms to me as I walked around in wonder. The sheer number of things that had to go exactly right for all the data to be collected and all the systems to function properly was mind-boggling. In addition, most of the equipment needed is not built commercially, so the graduate students have to build it all themselves.

Imagine building a machine including liquid helium, pulse pumps, and yards of spiderweb-thin wire to make a machine that cools down an array of specially designed chips to feed out into a complex computer system you have to code yourself. Doesn’t sound so easy! But this is what the students must do. They are motivated by their desire to search the skies, and I can feel it too, even through the frustration Sara and Simon feel as they sift through mountains of data and run endless tests in order to find the problem with their machine.

Since yesterday, the array in the cryostat was running a little colder — a good sign after the 1o0 milliKelvin discrepancy of the day before. However, the gap wasn’t big enough, and the graphs the computer kept outputting from the complicated programming tests Sara was running were not looking like the uniform, smooth curves she was looking for. I cannot begin to understand how they kept themselves so calm, how they worked through the frustration they must have been feeling at the circumstances there had been no way to foresee. I admired their work today greatly — I can only think how discouraged and frustrated I would be in their situation. When Brian, their collaborator on the Green Bank Telescope, arrived they explained the situation to him and he sat down to work. While some tests were running, Sara also explained to me the science and concepts behind their experiment, including how changes in the Cosmic Microwave Background (leftover radiation from the Big Bang) can show us how energetic events are in the universe, and how the inflation period of the Big Bang happened in thousandths of thousandths of seconds to set the stage for cosmological formations.

Here is a picture of the CMB:
Planck_CMB

It was incredibly interesting and complicated. It is unfathomable and crazy — the way that we can look back in time using light that is only now getting to us from the far reaches of the universe during the early stages of the universe may be the closest we ever get to time travel. But that doesn’t mean we aren’t going to try, and the UPenn lab is the perfect place to begin to unravel the mysteries of the universe.

A Stranger in a Strange New Place: A Jewish Right of Passage

It’s 12 am, the end of my second day in Tel Aviv, Israel.  I just finished writing 15 pages in my journal and have yet to cover today… so yes, a lot has happened, and yes, I am exhausted.  The thing they don’t tell you about traveling is how challenging it is, especially alone.  At Westtown I can go into a friends room, but here I am my only support.  Thankfully I have wifi and can keep in touch with my friends, but in the end when I turn off my phone it is just me here.  I still try to dive into every situation with an open mind and have learned so much already.

 

The El Al flight was easy and, luckily, I slept through most of the chaos.  I have never been on a plane where people walk around so much.  At day brake, the Orthodox Jews stood in the aisle to do the Amidah (morning prayers) while crew maneuvered around passing out glatt kosher breakfasts and children ran around.

 

My first day in Tel Aviv was warm like the sun and cool as the sea breeze.  I had a wonderful roof-garden lunch with Nurid (with whom I am staying) and went out that night with some young Israelis.  The people here are so friendly and open, but they are very intense.  Everyone has served in the military and there is a sense of urgency about the impermanence of life.

 

Today I went to the Pelmach Museum and met young visionaries who work to improve the lives of Ethiopians and Palestinians. Tonight I had a very interesting talk with Avishay about Israeli politics and it is just as, if not more complicated than American politics.  I feel like this trip is a “right of passage” for a Jew because I am facing the contradictions of a Jewish state.  It is a state founded in the name of freedom, to be a refuge for the suffering, but has not fulfilled its promise to all its people.

 

I am safe and am in good hands.  My mind is expanding!  Part of me wants to run away and return to the safety of my own bed and the other part is filled with the adrenaline of the adventure.  Tomorrow, I am of with Amos to tour Haifa and Akko and then I will spend the Sabbath at a Kibbutz.

 

Until then, much love,

Hannah

 

 

 

 

 

 

 

Day 4- Monday, March 7, 2016

Today was a very soil-centric day! Last night after Dahoon’s post we watched the Documentary Dirt, an excellent film about the importance of dirt to our planet, food, ecosystems, and personal lives. When I woke up this morning, the hills were covered in clouds. I’ve been living in a little outdoor loft, so watching the sunrise is always beautiful. We did eight sun salutations with Teacher Alan, meditated while listening to the birds and chickens, and then did our chores.

Screen Shot 2016-03-08 at 3.09.10 PM.pngWe have ten chicks right now and they are adorable! They’ve been eating multiple bowls of feed a day and are growing rapidly!

Screen Shot 2016-03-08 at 3.11.56 PM.png

After chores we returned to the house and ate breakfast cooked by Gloria and Alba, two amazing Mexican cooks. They brought their granddaughter/daughter Maite with them today as well and gave us the gift of amazing eggs, tortillas, and beans.

Screen Shot 2016-03-08 at 3.11.21 PM.png

After breakfast we walked down to a field to meet Angel the farm manager and learned that we were going to be making dirt! We used machetes to cut down an entire row of Flemingia. Flemingia is a windbreaker plant that is cut-and-come again, meaning that even though we cut it down it will grow back in the future. It is especially important because it is a nitrogen fixer. Once it is cut, all of the nutrients in the roots go into the soil, while the top pieces are used in compost piles.

Screen Shot 2016-03-08 at 3.09.46 PM.png

After we cut the Flemingia, we met Mauricio and Eduardo, two campesinos about our age. We all worked together to build square compost lasagnas with layers of Flemingia, dried grass, earth and water. We added humus from previous years’ compost piles to introduce bacteria. This was the most beautiful compost I have seen it my life! I was paired with Eduardo, so we had a conversation about compost and compared the fertility of the soil at Westtown Mini Farm, the soil at other farms I have worked on, and the soil at Las Cañadas. I was so impressed by Eduardo’s physical strength, kindness, and ability as a farmer. It was great to practice speaking Spanish and make some new friends.

Screen Shot 2016-03-08 at 3.10.42 PM.png

While we were composting, Eric Toensmeier walked by! He is a visiting lecturer at Yale School of forestry, and he talked to us about carbon sequestration, compost, and nitrogen cycling. You should look him up! Here is the link:  http://www.perennialsolutions.org/

After the compost project, we went down to the bamboo bridge to go for a swim. Teacher Alan was a very impressive swimmer because he just jumped right into the cold water. The rest of us were a bit more hesitant. I was attempting to boulder on the side of the pool when a rock broke and I fell in! I am happy to say that this was my first (pretty shallow) deep water soloing fall as a rock climber. I also found some roots to climb on. The water was cold, but refreshing. After our swim we went back up to the house and ate some amazing rice, salad, beans, and malanga patties prepared by Alba and Gloria. We took a short nap, and then it was time for Teacher Alan and I to catch the chicken!

Screen Shot 2016-03-08 at 3.11.07 PM.png

Our dear chicken friend has been eating ants in the blackberry patch for several days. It was time for her to come back to the coop, so Teacher Alan and I headed down the hill to collect her. She did not want to come back, however. We spent twenty minutes herding her around through the blackberry rows. The bushes were prickly, so I nudged her with a stick to chase her to the corners of the field. After a very long time Teacher Alan finally grabbed her and I carried her up to the coop. We decided to name her Zarzamora for her blackberry-like personality. After the chicken adventure, we all went on a tour of the sewage system.

Screen Shot 2016-03-08 at 3.11.30 PM.png

The sewage system is made of compost! We learned about several different types of composting toilets, as well as the mechanical, solar and wind laundry system. All of these processes use zero fossil fuels, while the sewage actually contributes to the soil! Every factor of the process is taken into account, from air circulation, to solids and urine separation and fly capture. I was completely blown away by the beauty of these processes. After our tour and a short walk through the food forest, we returned to the house and watched an amazing TED Talk about humus. We learned about the importance of living soil and how it can help our nutrition, reduce climate change, filter and store water, hold the soil together, and sequester carbon. We discussed steps that individuals and communities can take to promote humus cultivation and solve climate change, and how we can apply these ideas to our own lives. If you haven’t seen this TED Talk, you definitely should! Here is the link: https://www.youtube.com/watch?v=8Q1VnwcpW7E Overall, today we learned a ton about humus and living soil, including how to create it, integrate it with the waste from our bodies, and how it could save the Earth. I can’t wait to see how we can use this knowledge to improve sustainability at Westtown. Thanks so much for reading and remember: compost is important!

Day 2 in San Francisco

With no morning obligations, Lily and I set out for a run along the cloudy bay. Although this sounds relaxing, the run up Lombard Street was absolutely terrible (both because it was hard and because tourists were watching us sweat). Back at the apartment, we decided to set of for the California Academy of Science Museum. We walked through exhibits on rainforests, Snakes, Earthquakes, and “The Colors of Life”, which showcased the purposes behind camouflages and reflections. Fun fact of the trip: you can tell how big a salmon population was each year by looking at the amount of nitrogen in each tree ring. Beyond animal science, we experienced the building science behind CAS Museum. We took an elevator up to their living roof, which showcased six of San Francisco’s most resilient flower and grass species. The living roof also served as a natural thermal balancing system. The thick dirt layers help to keep the building hot in the winter, and the plants block the roof from attracting heat in the summer.

IMG_6420.jpgIMG_6421.jpgAfter CAS, we made our way to a casual coffee shop interview with Pete Kauhanen, who works with the SF Estuary Institute, where we’ll be visiting later in the week. He talked about his initiative, Green Plan-It, which maps areas by bio retention level. What interested me most, however, was not his work San Francisco, but in Australia. Pete lived with a semi-nomadic tribe that uses a method called “fire-stick farming” to clear land of harmful underbrush for hunting. It’s the older women of the tribe who have the responsibilities of fire starting and hunting, mostly for lizards. These small, controlled fires help prevent raging wildfires that would be prevalent if not for this strategy. In the past these tribes were pushed away, but recent initiatives by the Australian government have included the co-management of national land with indigenous tribes. This symbiotic relationship is not only much more respectful to the tribes, but also prevents wildfires and helps to maintain park safety and health. The controlled fires also encourage biodiversity by creating sub-environments within a giant area, which are differentiated by the levels of foliage growth after a burn. This example shows us how we can benefit socially, environmentally, and even economically (less recourses went to massive fire forces), when we work cohesively and respectfully with indigenous people. Pete, Lily, and I discussed possibilities for relationships like these with the National Park Service in the U.S, but failed to draw any conclusions on the potential. Pete said that the tribe he lived in is being featured on the first episode of Cook, a new show on Netflix that Lily and I are about to watch. Goodnight Blog!

Computer Science Intern- Day 1

Today I began my first day as a computer science intern at IONX here in West Chester. Today I was getting setup with my new project and learning what my new project is. I had a few meetings to begin the day that taught me what IONX, and my boss Matt, wants from me. This picture is from one of my meetings where I was shown what I will be using to work on my project.

20160307_095422I learned only 10 minutes into the workday that Matt will be in California for the entire week, so I will not be working with him for now. I began my actual workday messing around with the types of code statements that I will be using, called queries, which allow me to analyze data. The project that I have been assigned is to analyze data from a couple of locations across the United States that IONX is using to test its new sensor system. I will be analyzing the data that the sensors give us and developing code, or queries, that can analyze the data quickly for any errors. Using computer programs to analyze the data is much quicker and easier than manually combing through thousands of entries to find errors. Today I began writing the queries with my coworker, Trevor. Trevor is the youngest person at IONX at only 23 years old. He and I are working well together where we have been talking a lot about other interests that we both share. He is teaching me some of the necessary steps needed to develop programs. I look forward to developing my computer coding skills with Trevor.

Houston, We Have a Problem

Murphy’s Law: Anything that can go wrong, will go wrong. Brilliant people have spent years of their lives working on cutting-edge technology, and unforeseen consequences can mean much more time spent on these experiments.

Simon’s worried face was the first thing I saw when I walked into the lab today. He was staring at the cryostat, a large, green canister, which was emitting a rhythmical squeaking noise as the pumps strained to cool down the inner lenses.

“It’s running 100 milliKelvin above where it should be right now. We’ve had it cooling for much longer than expected, and this is worrisome.”

0.1 Kelvin above where the temperature should be, within fractions of absolute zero, doesn’t seem like much of a big deal. For this project, however, it is devastating. The whole project depends on the temperature being constant and in a certain range. Without the correct temperature, the measure of heat using changes in resistance falls apart, as does the superconducting nature of the wires. Without the correct temperature, bright, energetic events in the universe would not even register.

Sara and Simon sat by the computer, looking at complicated, squiggly graphs and deciphering their secret meanings, gaining data from them when all I saw was a strange figure reminiscent of a Jackson Pollock painting. They plugged numbers into a code and the computer chugged out countless graphs. Trying to pinpoint the exact correct ways to make the cryostat function was proving to be very difficult. Hopefully, there is nothing wrong inside the cryostat itself, which would mean a few more days of work opening it back up, fixing it, closing it again, and cooling it down. As Simon and Sara work hard to fix the problem, I will be working on a balloon-borne telescope project tomorrow called BLAST — interesting stories to come on that!

Mexico Day 3- Sunday, March 6, 2016

Today was Teacher Paula’s birthday! We woke up a bit later than usual at 7:30 am and Teacher Alan leaded us in singing happy birthday outside of Teacher Paula’s window to wake her up.                                                             Screen Shot 2016-03-07 at 8.20.48 AMAfterwards, we went about our daily chores and got ready for breakfast. On top of getting ready for breakfast, Sam prepared some wonderful Banana bread inside the solar oven for T. Paula’s birthday. I’m very excited to eat some of that later tonight.

Screen Shot 2016-03-07 at 8.21.05 AM

For breakfast, Mekhi made most of the very delicious pancakes, which we had with either honey or store bought “maple syrup”. Along with the pancakes we had the usual yogurt with fruit and granola. After clearing up our breakfast meal, we devoted the earlier half of the day to learning more about the Grey Water system which, in short, filters the grease from the water so that the water we use in the house can be recycled for the plants and local vegetation. First, we added more rocks to the one that was just built down by the tiny house. Then, we left the sinks on in the tiny house so that the Grey Water system would fill up with water. While waiting, we hiked down to the creek where we crossed the bamboo bridge that was built in 2005 by the senior project that came.

Down by the creek we discovered a pump that was bringing the water from the creek up to the house we were living in. The pump operated by using the power of a water wheel which powered two pistons, which pumped the water up the mountain to a very large water container which we also hiked up to.

Screen Shot 2016-03-07 at 8.21.41 AM.png

At that point, the water traveled through pipes down to the house. After learning about how we were getting our water, we looked at the Grey Water system already in place up at the larger house. Not only did we get to see what a complete system looked like, but we also got to harvest some water lilies from the older system to bring down and plant in the newer system. The water lilies are placed in each tank to filter the soap and grease from the water that we use in the house.Screen Shot 2016-03-07 at 8.25.47 AM.png

After learning about the Grey Water system, we came back up to the house and had lunch. For lunch we had delicious spaghetti, which put us all to sleep for a quick nap. After the nap, we set out on a hike to the original cloud forest, which was about 30 minutes away. About 10 minutes into the hike, we encountered Vigo, a neighborhood dog who then followed us on the entire hike and back. We enjoyed his company very much.Screen Shot 2016-03-07 at 8.24.51 AM.png

When we got to the original cloud forest, it was amazing to see almost untouched wildlife. We crossed swaying bridges and several of us slipped multiple times. The hike was great, as we took in the beautiful surroundings in the company of good friends.

Screen Shot 2016-03-07 at 8.24.41 AM

Once we hiked through the cloud forest and hit the road, we turned back around and returned back home. Now as I am writing this, I can’t wait to eat the delicious dinner and sleep like a baby until tomorrow morning.

A Great Weekend for The Metal Moose

I mentioned in my first post that I really wanted to celebrate how amazing FIRST Robotics is. This weekend I took a break from my work to go to our first event of the season. We started our Saturday with a motor burning out during practice matches. Still, we quickly recovered and started our weekend with some good scores.

20160305_183650

Near the end of day one we were ranked 2nd. At the end of day 2 we were ranked 6th before playoff alliance selection. In the end, we finished in 5th and won the Creativity Award for our design.

20160305_171917

Our next event is in 2 weeks and then the home event at Westtown April 1-3.

I can’t wait to do more work on my quilt and dive into the history of this wonderful sport.

A Jo-Ann’s Journey

Friday night I went to one of my favorite places: Jo-Ann Fabrics

If you’ve never entered one of these stores it’s a candy store for the serious arts and crafts. I say serious because this is no Michael’s or A.C.Moore. This is the grown up version of craft stores where everyone’s super-talented aunt or neighbor disappears to every so often and emerges with what seems to be another quilt already half-done.

So how does fabric shopping work? Well, this is the quilting section. There are many other sections in Jo-Ann’s, but different types of fabrics work for different purposes. There are upholstery, apparel, stretch, flannel, and leather to name a few. Most quilting fabric is thin cotton dyed or printed with a color or pattern. There are generally three options for buying quilting fabrics.

  1. Fabric Quarters (Which Were on Sale!) – These are quarter yards of fabric sold individually. This is good for getting a lot of different small quantities. While there are less overall options versus buying from the bolt, they make the process a lot easier.

20160304_184047

2. Bolt – As I mentioned before, this way can have more options but is more complicated. The bolts are the fabrics wrapped around cardboard. You can get larger quantities of these and they are sold by the yards. ( I like the one below for the back, what do you think?) You get these hand-cut by the staff, which can take a while if there’s a line. You have to be careful when buying these because you may not know the width, which can change, and because the price can add up pretty quick.

20160304_18382520160304_185225

3. Remnants – I don’t have a picture of this but I love remnants. These are “created” when a bolt runs out with around a yard or less or if a fabric doesn’t sell. These are in small bins and are sold at the unit price.

I bought a…moderate amount of fabric along with some extra threads and supplies and set up my station on G2. That was Friday.
