  1. For my final trick, a blog post about blog posts! The assignment of blog posts, 10 a quarter for four quarters, has been a great way to make us think. It seems fitting to reflect on the blog post process itself with this fortieth post. I really think this is a good idea, whenever I sit down to do a post I enjoy the creativity involved, and reflecting on what I've learned makes me appreciate the scope of the class all the more. I definitely recommend that the blog posts remain as an assignment, and I am glad to have had the chance to think about physics on my own and through that process ge
  2. Physics is everywhere, all of the time. This seems cliche but I really am beginning to grasp that, as this year draws to a close. No matter what I do, every single day I make connections to the concepts from the classroom and life. I don't try to, but that is what taking physics does to you. It alters your perspective eternally, as things that simply happened before now hold within them staggering amounts of math and headache inducing levels of thought. At any time, a baseball in flight can become a kinematics problem, or any little interaction becomes an exercise in conservation of moment
  3. I completely failed to mention something I found fascinating in earlier posts, and I believe t deserves its own blog post. The amount of fuel needed to break orbit compared to that needed to maneuver in space is staggering, nearly all our fuel and stages are dedicated to breaking Kerbin's hold. I now realize that as silly as NASA's launches looked to me as a child, with their massive fuel tanks and enormous engines, that grvity his simply that strong. It takes a remarkable amount of fuel to break the hold of a planet like Earth, or Kerbin, and that is all due to gravity and atmospheric resi
  4. Our team landed on Minmus during this project, and other teams landed on Duna and Mun. All of these landings and moonwalks have me thinking about the future of space exploration for humans. For example, I have heard a lot of speculation about a manned mission to Mars recently. There are even some talking of colonizing. It was watching the Kerbals jump so high on Minmus that I realized I will never buy into that theory. Mars' gravity is less than half of earth's, at 3.711 m/s. I cannot believe that prolonged living at that gravity would do anything but destroy a body, a slower version of
  5. Our team in the KSP challenge, Brazanah Inc., won the water bottle rocket challenge this year. This is the second straight year I have participated, and have gained several insights through the process. The first main thing is the value of a parachute, and the power of drag forces. A simple parachute turned a modest rocket that did not go very high into one that lasted 5.85 second in the air, all through air resistance. Our parachute was only a few feet in diameter but the rocket slowed to a crawl after it deployed. It is almost enough to make me want to skydive (but only almost).
  6. Once we achieved orbit around the sun, I first encountered orbital nodes. These nodes are a fairly simple notion, as relative to a plane of reference there are two points of intersection with that plane. At one, you are crossing from underneath and are ascending, hence the name ascending node. The descending node is where you cross below the plane. While attempting to encounter a planet's gravitational field, we attempted to make our orbital nodes as small as possible, getting them to 0.1 degrees away from the plane. These nodes make sense, but I never would have encountered them without KS
  7. Space Planes! I only recently began experimenting with the space plane features of KSP, but they offer a wealth of information about drag and air resistance. The steering of these planes is so sensitive, that you really see how rudders and pitching affect flight. Also, placing aerodynamic caps on engines rather than leaving them flat noticeably alters acceleration and top speed capabilities of a plane. Trying to build a plane is also complex, as you have to consider how much wight the wheels can support, how to balance weight versus fuel, and aerodynamics. Space Planes offer a great insigh
  8. Here are the three concepts that I believe I will remember the most from the past year as I go on into life. 1) Momentum and Impulse: I cannot express how often as I watch sports or any kind of everyday movement I am reminded of momentum. Now, when I watch football and see a seemingly big hit, I do not react the same way if I see that the hit was delivered over a longer time, as I would expect, the players often walk away unscathed. Pool is another example, as it is often the textbook case for sample problems regarding conservation of momentum in inelastic collisions. However, the most co
  9. There is so much to talk about regarding our final project of the year, using the game Kerbal Space Program to explore interplanetary physics. At first, I had no idea how the game could actually teach us about physics. Then, we tried to go into orbit. The accurate depiction of momentum as you try to lock on to a location with S.A.S only to have your rocket oscillate as it slowly loses its angular momentum is a nerve racking and accurate simulation. In a less obvious fashion, learning when to make burns in order to be as fuel efficient as possible helps you get a great feel for gravity and orb
  10. Well, with one more day to go, I would like to attempt to capture a year's worth of memories in a few short words. I have never thought so hard, been so frustrated, or studied so much in my life as I did for Physics C. Despite all that, or maybe even because of it, I wouldn't trade the experience for anything and given the opportunity to do so I would take the class again in a heartbeat. Having a class that forced me to struggle to understand the base concepts, to work just to establish a foothold, was a great preparation for college. If anyone reading this is on the fence about taking this

  12. Brazanah won the bottle rocket contest for a bonus of $150,000. We now have $311,109.
  13. Launch Time: 9:15 am Team Members Present: Zach, Matt, Hannah, Mark Malsby Kerman’s Flight Recordings, compiled each night after that days events. Day 0: Tomorrow I will pilot the improved design of Kerbin’s finest ship, To The Mun, in an effort to reach Minmus. Tomorrow I simply must pilot us into orbit, by using the first engines to break the atmosphere. I will then disengage those and use some of the middle engine to establish orbit.Day 1: Today was exhilarating, I am now orbiting Kerbin following a smooth ascent to orbit. The ship shook and rattled but the SAS did its job and we stead
