Re: Pennsylvania 2019

I found it interesting how our ES's came 15 minutes late and only gave us 45 minutes... -_- They didn't even explain any rules or anything... they just... came late. And when they called time, I asked for another 5 minutes because we're suppose to have 50, but they said no because they didn't want ...

Re: Pennsylvania 2019

Astro: Astro: Great test as always. One math question wasn't great, there was really just the first part that was difficult and obscure, but the actual astro math was pretty easy. Some of the conceptual DSO questions seemed very obscure, but that was probably just poor notes on my parts. Overall, lo...

At this point, since it's been more than a week since the Southeast regionals, if anyone has the overall scoresheets (NOT event scores) for that regional, they can be uploaded to the wiki (ideally as "PA Southeast Region 2019 B Results.pdf" and "PA Southeast Region 2019 C Results.pdf...

Re: Astronomy C

I'm having a bit of trouble with notes on "galactic structure and interactions". What kind of knowledge on this do you think would be expected? A similar question applies to most of the rules, so it helps to narrow in on what's the issue (even if it's just "where to begin"). Is ...

Re: Astronomy C

While you're here - would you happen to know whether to use distance or half of the distance in Kepler's third law? I've seen it both ways in the past but no one I've talked to seems to have a definitive answer on this. Never mind I was wrong you do actually use the separation for “a.” (And not jus...
