I enjoyed watching your video! Your project seemed really interesting and impressive, and I'm interested to see where it goes next. Best of luck for the second summer!

Hi Rojeh, I was really interested by your response because it's often too easy to ignore both the great diversity and tension within religious and ethnic groups. When we see others' identities as monolithic, we ignore this complexity. Thank you for highlighting this! Also I agree--CLIO is a lifesaver. I can't imagine what this summer's research would have been like without it.

1. One of the goals for my project is to examine and re-simulate some past results (and then build off of them). However, I'm often struggling to follow some of the mathematical derivations for these past theories. For example, under many circumstances, turbulence in an ionized gas can cause it to generate its own magnetic field, and there are theories as to what these precise circumstances are, and what shapes of magnetic fields can form. However, I'm having trouble making sense of these theories, since I haven't taken classes in many of the tools that are involved in their math. Additionally, I'm using a piece of software to conduct computational simulations of this turbulence, but I don't really understand how this software works, which is important for me to to give the right input data and understand its output data. These challenges have really shown me how large this project is and how long it will take. This summer is only the first step in my project, and I still have a lot of interesting work to do, especially since  the goals of this project have changed as well. Now, rather than examining the dynamics of stars such as our sun, I am now modelling what happens in neutron star collisions. This has been a challenging but enjoyable shift, since we now must also consider the relationship between changing magnetic fields and fluid turbulence. However, I'm excited for this shift, because neutron stars are really interesting.

2. Zotero has been useful for keeping all of my papers organized.. Also, the Python tool "Jupyter", has been really helpful in certain stages of the project because it makes it easier to experiment with different ways of analyzing data by continuously showing my code's results in "real time". Clio and the Northwest Corner library have been helpful because they contain some great textbooks on my topic. Also, the school's supercomputing resources have helped me to run simulations at higher resolution levels than would be possible on my laptop.

I really agree with you that this summer is really only the beginning of a more in-depth project, and although now it's somewhat sad to have to de-prioritize certain parts of our projects, we'll definitely have time to work on them later. It's amazing how deeply your project is tied to cultural and social movements, so I bet it could have a big impact.

1. My research this summer is part of a larger project that will likely continue through my second and third years of college. It will likely culminate in a paper. However, this paper will probably not be ready for at least a year or two, as I am only beginning to produce novel results. This summer, I have mainly worked with my mentor to build a foundation of how to apply some of the tools that astrophysicists use when studying turbulence. I've gained a mathematical understanding of how energy flows in fluids, and a practical experience in the use of simulations to perform experiments. I expect to continue to use these throughout the study while continuing to learn the mechanics of what I'm studying.

2. My research matters because it will aid us in the detection and observation of largely unknown phenomena. Part of my project involves understanding the evolution of neutron stars' magnetic fields after they collide. These magnetic fields are expected to drive gamma-ray emissions, which are observable. Therefore, by producing quantitative predictions of how their magnetic fields work, we can eventually determine what radiation signatures to observe and produce hints on how to interpret them.

You raise a really interesting question, and I agree that on principle, we should not take, research should only give. However, your last sentence also resonates with me, that as even though you take in the short term, you give much more in the long term. On the other hand, the Botanical Garden seems like a great partner, considering their goals and the diversity of the species they keep.

. My research project seems pretty devoid of ethical implications, issues or otherwise. However, after further thought, I realized that the methods I use are deeply rooted in some of the fundamental ethical issues facing modern society. Nearly all of my analysis is done on computer processors, whose production involves human rights abuses, environmental degradation, and exploitative politics. Sustainably sourced computer processors are virtually nonexistent, so my project, in part, rests upon such abuses. I am not sure how to respond to this issue.

2. One significantly helpful perspective shift I employ in my project is that of taking the perspective of a particle of fluid. For example, when imagining myself as a molecule of fluid in my experiment, I can better visualize the forces that act on it in a way that simply seeing the equations of motion would not. This perspective has helped me to qualitatively understand important laws and concepts for which I lack some expected background knowledge.

Your comment on considering bias while investigating a source is really interesting, since it made me realize how much our society and background shapes the way that we might interpret anything from song lyrics to datasets. I agree with your idea that one's language can sometimes provide a limiting framework when representing a different culture, and it applies to my own project because it mirrors the fact that often one loses important information when making choices on how to represent data or simulate a problem.
