Constructor: Jesse Guzman
Relative difficulty: Medium-Challenging
- DOS AND DON'TS (17A: Some basic guidelines [2, Spanish])
- FIRE OPAL (26A: Fluorescent gemstone [4, Danish and Norwegian])
- OTTO HAHN (44A: Chemist who co-discovered 26-Down [8, Italian])
- SEIZE THE DAY (52A: Carpe diem [16, French])
Fission is the process by which an atom splits in two. Fission can occur spontaneously, via natural decay, or through controlled chain reactions initiated by people. Either way, the process releases a tremendous amount of energy. Nuclear power plants harness this awesome power, but so do nuclear bombs, and there are myriad environmental, social and political concerns raised by human use of this process. // An atom contains protons and neutrons in its central nucleus. In fission, the nucleus splits, either through radioactive decay or because it has been bombarded by other subatomic particles known as neutrinos. The resulting pieces have less combined mass than the original nucleus, with the missing mass converted into nuclear energy. (Live Science dot com)
In nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series or "positive feedback loop" of these reactions. The specific nuclear reaction may be the fission of heavy isotopes (e.g., uranium-235, 235U). A nuclear chain reaction releases several million times more energy per reaction than any chemical reaction. (wikipedia: "Nuclear chain reaction")
The dominant contribution of fission neutrons to the bomb's power is the initiation of subsequent fissions. Over half of the neutrons escape the bomb core, but the rest strike 235U nuclei causing them to fission in an exponentially growing chain reaction (1, 2, 4, 8, 16, etc.). (wikipedia: "Nuclear weapon design") (emph. mine)
The FISSION part of this puzzle is confusing to me, and not ... necessary? I'm just not sure what it has to do with foreign numbers (or baseball). I mean, yes, you have a series that you have to account for, i.e. "why this series of numbers?," but FISSION? Just because your "8" answer is the guy who co-discovered it? This feels so arbitrary to me. I'm no longer asking "why this series?" but I am still asking "why?" There's no clear / natural / automatic connection in my mind between the series 2, 4, 8, 16 and FISSION. At first I thought FISSION was totally unthematic, and that the puzzle had decided to do this mutually cross-referencing thing with OTTO HAHN because he and FISSION just happened to end up in the same grid, so why not? But it seemed a big distraction. Why would you cross-reference one of your themers? Why would that cross-reference sit dead center, which is where thematic material might naturally sit? I would've ignored FISSION completely if the cluing on OTTO HAHN hadn't forced me to wonder what the hell was going on. So the (foreign, for some reason) numbers are (I think) supposed to represent a nuclear chain reaction, a splitting and resplitting (of uranium-235?). But I still don't really get why the puzzle goes nuclear at all. Or what the nuclear bit has to do with specifically foreign numbers? Or baseball? Lots of things happening in this puzzle, but their relationship to each other doesn't make much sense to me. The WORLD SERIES does start this week (Friday), so the baseball part, at least, is timely. The part where we celebrate The Bomb? Or the numbers of the world? That, I understand less. I hope you understood and (thus) appreciated this puzzle better than I did.
What else?:
- 39D: Young woman, in Australia (SHEILA) — I've been to NZ many times because that's where my wife was born and where her family lives, but in the half dozen or so times I've been Down there, I've somehow never been to Australia. I'm hoping maybe next time we get over there. Don't think I'll be calling anyone SHEILA, though. Seems like a neutral enough word. Brief online inquiry suggests that the term is maybe less commonly used today, and perhaps seen by some (in some contexts) as derogatory or condescending (the discussion on this Reddit thread is interesting), but again, not having any direct familiarity with the place, I can't say.
- 55A: Picasso's "___ Demoiselles d'Avignon" ("LES") — I knew this, and yet some part of my brain was like "are you sure it's not 'DES'?" So I left the first letter blank and eventually SOMALI confirmed the "L."
- 54D: Subculture associated with skinny jeans (EMO) — is this still true? Feels like a 2004 stereotype, but maybe the aesthetic persists. Wikipedia agrees with me about the '00s-ness of it all. "Emo fashion in the mid-to late 2000s included skinny jeans, tight T-shirts (usually short-sleeved, and often with the names of emo bands), studded belts, Converse sneakers, Vans and black wristbands. Thick, horn-rimmed glasses remained in style to an extent, and eye liner and black fingernails became common during the mid-2000s." (wikipedia)
If nothing else, this puzzle taught we the Norwegian word for "four," which I'm sure to forget by tomorrow, but for now, I've learned something.
