  1. I have family in Tofino and they do have tsunami warning systems. There are sirens, and there also are signs along roads to show the most effective evacuation routes. I noticed it when I visited them a few years ago.
  2. Is this the sort of thing you're looking for? http://nuclearsecrecy.com/nukemap/
  3. Guys, this was solved a while ago. Sorry to kill the fun. http://www.westerngazette.ca/2014/04/07/weldon-coded-notes-mystery-solved/
  4. Bop in Alternis Kerbol is only a few kilometers across, and the mountains are gigantic. No matter where you land it's spectacular.
  5. I'm so conflicted right now. I really want to use this mod, but it seems to be incompatible with Alternis Kerbol, and that's where my current career save is.
  6. Wheaton Armory from Fallout 3, if memory serves.
  7. Ah, I understand where the confusion came from. In the lesson on circular motion we never distinguished between average and instantaneous acceleration. We only did three problems where we found the circular acceleration, and they all used the formula I tried. He even specifically said that for these questions we would only need the magnitude. When I saw the question, I saw circular motion and a magnitude-only response, and assumed it was the stuff we did in class. Thanks for the help.
  8. I have a question regarding acceleration in circular motion that I was hoping someone on this forum might be able to help with. I had a physics test in which I did unusually poorly, and I am unsure why. The teacher posted the solution to the question online, but it left me unclear as to what his intent was. The question was as follows: A traditional watch hand has a second hand 1.45 cm long from centre to tip. What is the magnitude of the average acceleration between 30 s and 50 s? In class, we had only briefly covered circular motion, but I remembered the equation we'd used: Since the motion of the hand is constant the acceleration should be constant as well. To be safe, I tried the equation twice, once over the 20 s interval and 1/3 the circumference, and once over the whole 60 s. Both times I got an answer of 1.6*10^-4 m/s^2. However, when I received the marked test back, I had been given 1.5/8 with the note "not reasonable". I know I lost 1/2 a mark on my diagram; I'll admit it was a lousy one. The other mark I did get was for my final answer, since, while different, it complied with notation and significant digits. Several days later he posted his solution on his website: What was wrong with my method? Every circular question we'd done previously had worked with the equation I used. I considered that perhaps my solution was for instantaneous acceleration rather than average, but for an object with constant speed shouldn't those two be identical? Can anyone see where I went wrong?
  9. Holy cow, there's 18 now? When I last heard about them they'd only found 3. I'm planning on going to this university next year, do you think if I crack these notes I'll get a scholarship?
  10. I had a pretty lousy programming teacher once. The entire course was a series of online tutorials that he'd found (not made) so I watched them all without doing any of the practise, then did the final project. This was entirely in the first quarter of the semester. I played Skyrim on my laptop every day in that class for three quarters of the semester. I got 98% and an award. The teacher never learned which student I was, he only knew my name from the hand-in folder on the computer. On my report card he heavily praised my work ethic. Regarding what SkyHook said last page, yes I most certainly did have a poor attitude in that class. But only because the teacher sucked.
  11. You don't measure the orbit of the object in question, but rather the orbit of the other body around it. Even with the mass difference of an exoplanet orbiting a star, the planet's mass causes the star to move a detectable amount. The petunias are so small that their effect on the sun is negligible, and we wouldn't be able to even detect them. Jupiter, on the other hand, does have a noticeable impact. The barycentre of the system is just above the sun's surface; i.e. the Sun and Jupiter both orbit a point very close but just outside the sun. This motion is detectable. Since we know the period and the radius of the sun's movement, we can calculate the mass and distance of the other object.
  12. I figured that since nobody was submitting anything to the unmanned category, I'd toss something together quickly. Yes, there is some mod stuff visible, but none of them would do anything to affect performance. The craft itself is stock.
  13. I see several people talking about how unpleasant their religion classes were. Why were you still in that school system instead of the public one? Parental pressure? Or was that the public one somehow, and if so, what country would do that? Anyway, my worst teacher. Up until grade seven, I was quite fond of French classes. I enjoyed, and still enjoy, learning other languages (French is tragically the only one I've been able to study in school). However, partway through the year, the French teacher just didn't come into class. We all sat there, gradually getting more and more chaotic, until the bell rang and we left. The next day, the teacher once again failed to show up. On the third day, a teacher I didn't recognise came into the classroom looking very serious. It turned out the French teacher had been arrested for sexually assaulting a student from another class. I never met the student, so I don't know how she dealt with it. Nobody else in the school was qualified to teach French, so the class was cancelled for the rest of the year. The "replacement" for grade eight wasn't really able to teach French either, so we all had a lot of difficulty when we started high school. The high school's teacher, while fortunately not a criminal, was only somewhat better than the other teachers in this thread. She spent three weeks teaching us how to use Powerpoint, without using a word of French. She didn't know how to use Powerpoint. She taught nothing, instead making us do the same project over and over. As in, the same topic and the same criteria in the same format. At least four times. There was only one project not to follow this: an essay about teenagers. She only accepted topics complaining that our generation was far worse than hers. I had her class the next year, and dropped it the first day. So, yeah. A paedophile teacher got French class cancelled for a year and a half. The next real teacher was awful. French has been ruined for me. And, of course, I've had the standard Marxist social studies* teachers who cater to the stoners. I was once legitimately praised for being able to read from the Charter of Rights ("That's third-year law school [crap]!"). Of course, everyone's had one or two teachers like that; they were nothing on my French teachers. *The main thing they taught me was not to dignify the fields with the term "science."
