   honest question: what if your science isn't maths/physics/data? I'm a chemist and from what i can see there's @#$@# all out there in FOSS land.

   i (mostly) agree. i think thinking about a fraction of a full circle is the easiest way to work with trig. having said that, the mental overload on your average high school student flipping between pi and tau is too much. my personal com

   small clarification - that was $65k gross, not nett. sounds like a lot of it went back into broken/spare part purchases.

   cool. thx for replying back - maybe i'm a bit sensitive about this sort of thing but i'm tired of seeing students put in dangerous situations and then if/when something bad happens they're labelled 'professionals&#x

   speaking with my chemist's hat on... crying 'wimp' is one of the cultural problems we have when it comes to health and safety.

   good question. complex answer. you need to have a good surface area on the electrodes. the hydrogen ions will bond on the surface to form H2 which will eventually bubble and literally float to the top. O2 on one electrode and H2 on the o

    speak for yourself (or for other top-10 schools) - i worshiped my rice cooker for filling my belly day in day out for 50c a pop. i got about $10k per year and even in the mid-90s that was !#@!@# all.

    can't watch any of them without signing up or you work in the ivory tower. pity, it would have been nice to use as an instructional aid. and no way i'd shut my lab for 2 weeks - if you're interested send your own damn post-

    If the original title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys.&qu

    you're not the target market - every scientist and mathematician initially and recently home hobbyists. BTW once you leave uni, paying to be productive is the easiest decision you'll ever make - half arsed and free isn't all

    I think i'm supposed to point out here that NZ (and Aus) has had a free national POS system in place since the 1980s called EFTPOS. really weird traveling in the 90s and having to start thinking about cash again... It works wonderfull

    on off the cuff comment: try targeting Aussie or Kiwi companies - we've got our share of workaholic nutjobs and there is probably a bit of selection bias but it's culturally acceptable to want a couple weeks off in summer (which i
