Here are some arts and STEM topics ideas for this year's NHD theme! I expect it to be a pretty low year for both arts and STEM projects; "Conflict and Compromise" isn't the easiest theme for either one. I'll be adding to this post for the next month or so.
STEM
-- The War of Currents (AC vs DC current). This has had a winner to an extent, but there are a lot of ways in which we still use each of AC and DC current today, so this does feel like it involved a compromise to me.-- Wave-Particle Duality. I feel a little odd calling this a compromise, but the answer to "Is light a wave or a particle?" is well, yes. It took us a while to figure that out, and the history of the experiments and discussions that finally led us to the current model is really interesting.
-- Galileo. This was recommended in the theme book, maybe because Galileo compromised his values in recanting, maybe because he had earlier come to a compromise with the church (and then in the church's eyes crossed the agreed upon line). I'm hesitant to strongly recommend this topic because of its familiarity and applicability to a wide range of NHD themes.
-- Ethics of Human Subject Research. This is pretty broad, but it's a subject based on compromise. Biomedical and behavioral research is often very valuable, but we need to do it in a way that is safe and respectful of the people involved as research subjects. Key documents to consider: the Nuremberg Code, the Declaration of Helsinki, the Belmont Report, the National Research Act of 1974.
-- Munsell Color System. This paper argues that Albert Henry Munsell's system of describing color was a compromise that largely resolved a conflict around color science. It might be difficult to use this paper as a starting point; either it makes the argument you want to make, or you effectively argue against it. But this seemed interesting, so I wanted to throw it in.
-- Endangered Species Act. The ESA has existed in several forms and has been amended a number of times, generally seeking compromise between industry and protection of species.
-- Echo Park Dam and Glen Canyon Dam. Glen Canyon Dam was the compromise after there was controversy about the proposed Echo Park Dam, which was on protected land. (There are also similar other projects that you could look at; I found an Army document about development of the Snake River titled "Controversy, Conflict, and Compromise: A History of the Lower Snake River Development.")
-- Apostle Islands National Lakeshore. This park includes less area than originally planned because of Native American (especially Ojibwe) activism advocating for their land rights. There are probably other cases of preservation or conservation movements and Native American land rights coming into conflict that you could look for.
-- Cooperative Game Theory. So this is a kind of sideways take on the topic, but cooperative game theory is a mathematical field founded on ideas of conflict and compromise. Looking at its history (and in particular the early work of John von Neumann and Oskar Morgenstern) would be really cool and, I think, unique.
Arts
-- Ballet in the early Soviet Union. In the 1920s, there was a lot of discussion in the Soviet Union around ballet as an art. It had a strong history in Russia, but it was tied heavily to the nobility and especially to the tsars. It was virtuoso and didn't tell stories of the common people... but the classical, Imperial-era ballets still drew huge crowds. I think one could do a good project about that conflict and how the leadership eventually reconciled ballet with socialist ideals. Book recommendations: Swans of the Kremlin, Apollo's Angels, Bolshoi Confidential.-- An Actors or Writers Guild strike; there have been several large ones in the US over the past century. Most labor negotiations involve a lot of conflict and compromise, and some of these have had major impacts on the affected industries. (I'd recommend against the Disney animators' strike because of the minimal compromise involved.)
-- Vietnam Veterans' Memorial. Maya Lin's design for the memorial was controversial, and more traditional memorial elements were added to the plans as a compromise.
-- Rodgers and Hammerstein. This is suggested in the theme book, and the reasoning isn't entirely clear, but here's my best guess. Several R&H shows have liberal political messages but don't fully commit to them. (South Pacific has a good deal of uncondemned Orientalism while also addressing racism and interracial marriage, for example.) Robert Gordon's The Oxford Handbook of Sondheim Studies definitely refers to this as a compromise.
