Greetings, friend. I have strong interests in essentially all fields of science, especially physics and chemistry (my favorite chemical element is probably boron (5B)). However, I enjoy gathering knowledge on a prodigiously wide variety of topics, from history to linguistics, and everything else that is metaphorically in between those two fields. I also enjoy expounding upon subjects and explaining things to people. I am very quick to identify and rectify any grammatical and word-usage mistakes that I come across, and I would imagine that such skills can be applied to Wikipedia with a beneficial outcome. Finding pretentious ways to say everyday things is a silly hobby of mine. I spend most of my time reading, but I also play the bass guitar (it's just as cool as a six-string, I swear!) and trumpet, and I am a rather large fan of this band (and I like to put on this band to annoy my friends when they're in my car). I am strongly in favor of increased rights and representation for gay folks, trans folks, women, and ethnic minorities. For a variety of reasons, I would describe myself as a socialist with anarchist tendencies aligned firmly against capitalism and the systems of neocolonialism that it upholds (not to mention the cheapening of life, both human and otherwise). To answer your pressing question, no, I don't like Stalin. Anyway, I've bored you enough. Duty calls.

This is a Hertzsprung-Russell diagram (yes, I did just copy it from the page). It displays stars of various stellar classifications according to magnitude and temperature (though all sides of the diagram are labeled). Hertzsprung-Russell diagrams are both interesting to study and nice to look at. That actually describes quite a bit of astronomy.
This is an animation of ideal Cherenkov radiation that I took from the Cherenkov radiation page.
