  1. Fantastic blog post, and a great start on understanding some of the conceptual ideas around time dilation!
  2. Full contact billiards... cool!
  3. That's a mighty cool looking stick!
  4. Never thought of applying conservation of energy to minions... Unique!!!
  5. Nice summary of our last unit!
  6. Wow, learned all sorts of pokethings I didn't know before!
  7. Have you ever tried to make it? How did it come out?
  8. Wow, that's some mighty creative problem writing!!!
  9. That is a paw-some blog post about cats. The physics behind them always landing on their feet (or usually) is meownificent. Great job jumping on this blog post and avoiding procatstination. No kitten, this is pawsitively fantastic.
  10. Used to go to Rock Ventures all the time (nearly 20 years ago) -- it's been around for a while now. Cool stuff -- love all the tensions and physics in the knots!
  11. Looks like several paragraphs all on the same topic -- could perhaps be combined into a single post...
  12. Dropped my daughter once... didn't notice the air resistance kicking in. Did notice the mom resistance kicking in shortly thereafter, however.
  13. If you have a chance, read up a bit on Chuck Yeager (and/or follow his Twitter). An amazing man with an amazing career and a fantastic sense of humor to boot.
  14. Love this! My background is in microelectronic engineering, and I'm even in the middle of putting together a 2-hour workshop on microelectronics (presentation is in December) that will cover much of what you did over the summer. Great discipline, with TONS of fantastic jobs that are fun, challenging, and rewarding. We'll have to talk more...
  15. Old Silverback is my favorite player!
  16. Which is certainly closely enough given various rounding / sig figs. You got it right.
  17. There are several explanations I think. I would probably use the kinematic equations (v0, v, delta_x, a, t), and use those to solve the problem. If you're getting stuck, can you post what you've done so far, and that will give me better information to assist you?
  18. Hi cjt100. So we can better assist, can you tell us what you've tried so far, and where you're getting stuck?
  19. Sure would be nice if your teacher put something together to help with LaTeX and getting started... maybe something like a guide and even starting templates. Perhaps even a video guide? http://www.aplusphysics.com/about/LaTeX.html
  20. This is a very common type of question, and the process of breaking up forces on a FBD into components and applying Newton's 2nd Law carries throughout the entire course. One of those things you've gotta learn. The "shortcut" that you learned isn't really a shortcut, and isn't something I'd recommend, as it won't carry through to other situations in which the third force isn't caused by gravity on a mass. I'd focus on learning how to draw free body diagrams, break forces at angles into components, and applying Newton's 2nd Law. It's the backbone of mechanics, and very important in further units as well. Good luck!
  21. That was a pretty cool read... I had no idea about all the different split configurations. Well done!
  22. On the bright side, replacing circuit breakers is fairly straightforward. Car engines, now... that's another story. Good luck!

    @HegelBot153 Huh???
