    I Learned Something Today

    This thread is intended to be a place for cool things that you just found out about, but that aren't necessarily major enough to merit their own thread. For instance, today I learned why heavy water is/was used as a moderator in certain types of reactors. Since hydrogen atoms are small, they are very good at slowing down neutrons, but regular hydrogen also has a nasty tendency to absorb said neutrons (which you probably want to be absorbed by the uranium/plutonium in your reactor). Deuterium is a bit heavier, but still pretty damn good at slowing neutrons, and it's much less likely to absorb them.

  8. This is the official thread for discussion of anything related to skiing/snowboarding on SH. If you like throwing yourself down a frozen mountain, or are at all interested, this is the place. My personal experience: I mostly ski in the northeast (New York / Vermont), have never tried snowboarding. All my experience is at resorts, so if you want to know more about crazy backcountry shit I might not be able to answer 100% (though I am seriously considering heading to Tuckerman Ravine this year). Basic advice: Wear a helmet Rating systems are uniform everywhere, what's a black diamond somewhere might be a blue at a more hardcore place. Anything above black diamond (and especially above double black) is as much marketing as difficulty rating. Difficulty depends on conditions Wear a helmet Taking a lesson your first time is probably a good idea Make sure your boots are properly fitted Resources: http://www.skibum.net/ Site with a bunch of general info about skiing, and has little blurbs/ratings about a whole lot of American ski/snowboard places, grouped by state (surprised how many midwest states have ski places). Has a pro-ski / anti-snowboard tilt. https://www.liftopia.com/ Deals on lift tickets (it is an expensive hobby, especially if you go to Aspen or Vail) http://nyskiblog.com/ Blog about New York skiing http://forums.alpinezone.com/forumdisplay.php/10-Northeast-Skiing-and-Snowboarding-Forum Forum about skiing in the Northeast https://www.tetongravity.com/forums/ General skiing forum, but has more of a western audience. Also appears to have a vibrant shitposting culture. http://mountainvertical.com/ Shows de-marketified vertical ratings for each mountain. Vertical (distance from top to bottom) is a big deal for marketing, and there's a lot of ways to fudge it. http://www.goremountain.com/ http://www.whiteface.com/ The two places I go most often. Whiteface has more vertical and longer runs, but is farther away and is often windy and iced over. Gore is closer, less crowded, and sometimes has better conditions. http://timefortuckerman.com/ Site about Tuckerman Ravine, one of the holy sites of Northeast skiing. https://www.youtube.com/channel/UCzmlnH8vDQHoEb2TrC0WDCg Jerry of the Day Pic at the top is from the summit of Whiteface about a year ago.

    Pentaborane A Study of Pentaborane
  12. For stuff that's cool, but isn't necessarily important enough to merit its own thread; to start;
  13. For discussion of all sorts of weather and weather related phenomena. Post cool shit, or just talk about what it's like outside. First, here's a cool pic of some sprites; Also, we're just now starting to get into hurricane season (although it actually began about 5 months ago with Hurricane Alex)! The US has dodged a lot of bullets recently, there hasn't been a landfalling major hurricane in the US since 2005. The biggest story in the Atlantic for 2015 was Hurricane Joaquin, which reached category 4 intensity over the Bahamas despite its unusual method of formation, and sank the cargo ship El Faro; The East Pacific had Hurricane Patricia, which produced the highest winds ever recorded in a hurricane, and the lowest pressure ever recorded in the western hemisphere (872 mb) Side not, California hasn't been hit by a hurricane since 1898. Maybe this is the year they'll get unlucky!
  14. In case you weren't already aware, hurricane season started early. https://www.nhc.noaa.gov/text/refresh/MIATCUAT1+shtml/280006.shtml I don't know off the top of my head, but preseason hurricanes are pretty rare. Only one I remember without more research is Alex in 2016, and that was in January.

    Arianespace CEO Yells at Cloud

    I also want Arianespace to stay in existence, because as you said, more competition is good, and Europe has done a lot of good in space, especially in the scientific arena. It's a shame their CEO seems determined not to do that. They probably did a quick calculation and determined it would be more expensive for them, without taking into account all the vertical integration SpaceX has, and that Falcon 9 has been designed for reusability from the outset. I'm sure if you tried jury-rig a stock Ariane 5 for reuse it'd be expensive as hell. Or, his brain is damaged from all the fluoride Jeff Bezos is putting in his water.

    Arianespace CEO Yells at Cloud

    Put this in its own topic instead of the space thread because it deserves its own discussion, and is darkly hilarious. SpaceX and its low launch costs for the Falcon 9 have already been squeezing Russian launch providers and ULA out of the market. This will only get worse if the Block 5 Falcon 9 provides the advances in reusability that are promised (and if BFR lives up to Elon's dreams it will blow everything out of the water). European launch provider Arianespace has been feeling the heat too; their Ariane 5 is a reliable but dated (compared to Falcon) architecture, and the Ariane 6 is an incremental improvement at best, which lacks reusability (and uses a hydrolox/solid first stage for some reason). The major German publication Der Spiegel recently interviewed Alain Charmeau, the head of Arianespace; http://www.spiegel.de/wissenschaft/technik/alain-charmeau-die-amerikaner-wollen-europa-aus-dem-weltraum-kicken-a-1207322.html An English summary/discussion can be found here; https://arstechnica.com/science/2018/05/ariane-chief-seems-frustrated-with-spacex-for-driving-down-launch-costs/ There are some choice quotes in that article; Still cheaper than ULA. Also, US government payloads have more oversight/stricter requirements than commercial payloads, which drives up costs. About two sentences later he admits that Arianespace couldn't exist without subsidies from European governments. Next part; Obviously Elon Musk thinks it is, otherwise he wouldn't be telling his for-profit business to develop reusability. Also, considering that Falcon 9 (especially Block 5) isn't an utterly ridiculous architecture like STS, it's certainly cheaper to reuse. Here's the real money quote; "My subsidized jobs program can't compete with SpaceX because they get government contracts!" Still better than SLS though. Also, Blue Origin is going to steal your identity;

    Domesticated Foxes

    Something I haven't seen discussed on this site before; Soviet/Russian efforts to domesticate foxes by breeding for domesticated behavior. Article in Scientific American here; https://blogs.scientificamerican.com/guest-blog/mans-new-best-friend-a-forgotten-russian-experiment-in-fox-domestication/ Interesting that there were physical changes correlated with the behavioral changes the Russians bred for. Buy one for only $7,000! https://domesticatedsilverfox.weebly.com/aquiring-a-tame-fox.html (not entirely unlike a dog I guess) It seems like a pretty cool idea to drunk me, though I don't have a spare 7,000 dollars laying around (thanks student loans!).
