Hi, it looks like you landed on my page! I'm gz839918, and I'm fascinated in how the world works, but also how people think about how the world works—in other words, I like physics and cognitive science. I'm a student at the University of North Carolina at Chapel Hill, where I'm studying physics and linguistics. Outside of my usual areas of interest, I still enjoy learning new things in ecology and in various social sciences. Despite my experience with physics events, I am still incredibly terrible at classical mechanics.

Science Olympiad is about people, not about winning! Indeed, science is about people, not winning, because science is the scaffolding of humanity—a skyscraper in ceaseless upward construction built to carry the common good of people. If you like helping people, so do I! So, if you'd like to talk about science or people or both, please don't hesitate to message me. (If you hesitate, you can still contact me anyways!)

Oh, and for those reading this for my credentials—I made it to states exactly once; I've been to nationals exactly once; I was the only senior member in my year to medal in nothing at nationals; and I've only competed for two years. You know—the usual thoroughfare.

Some of the things I've volunteered for 

Errata

  • Raymond Park 2019-20: in the solutions, Mach should be capitalized.
  • Duke 2020-21: in the solution for problem 7, the sentence beginning "For a sinusoidal wave" should have all instances of (B) replaced with (C). The correct answer choice to this question remains the same.
  • General clarification about noise: with respect to sound, noise can have two definitions. In the first definition, noise is a wave with a stochastic frequency distribution. So, the more randomness in a sound, the noisier it is. This also means that noise can occur at the same time as "not noise" and still be, mostly, "not noise." For example, even the clearest, most crisply recorded audio of a note on a guitar may have a tiny amount of white noise in the background, but this does not mean the note is noise rather than music. In the second definition, noise is a wave that obscures another wave carrying useful information, but adds no useful information of its own. This means that noise can occur across time interspersed with "not noise" and still be "not noise." For example, the consonant [s] consists entirely of noise (in the first definition), but human speech containing [s] is not considered noise (in the second definition) when it carries meaningful information.

Did you uncover any typos or errors in one of my tests? If you'd like to discuss, I'd appreciate it if you could let me know! You can find me on my talk page, through private message, or one of the many other ways people can be found. On the version of each test on the test exchange, I have rectified as many errors as I can find; errata not listed on the test exchange are provided here above. You can also give anonymous feedback on my tests.
