  1. Very violent, but I have learned that cats end up at the wrong end of many physics demonstrations by now...I wonder why cats and not any other animals?
  2. In early September, in the very beginning of my time in AP Physics C, I was hesitant about the workload and difficulty of the course. When Mr. Fullerton introduced integrals to us for the first time, I knew from then on that the class would be no piece of cake. The funny thing looking back is that I enjoyed the calculus parts of physics by the end of the year very much. With a solid calculus background, the "hard math" aspect of the AP did not seem so hard. For me, the hardest part of the class was reading the problems and deciding in which direction to think. I had trouble reading the questio
  3. As graduating seniors, we are getting old. No more high school, it's off to college! But, just how old are we? On the earth we are about 18 years old, give or take a few months. Because the other planets are different distances from the sun, they have different periods of revolution. Therefore, in relation to many planets we are very young (Neptune) or very old (Mercury). A planet's period is given by: = distance from planet's aphelion to sun = distance from planet's perihelion to sun Periods of planets (in Earth years): Mercury: 0.241 Venus: 0.615 Ear
  4. I have always wondered this also. I never imagined that pruney fingers are the body's response to increase mew. Very interesting!

    Happy (belated) National Donut Day! This American day of celebration for sugary breakfast rings occurred yesterday on June 7. Yesterday, people from across the nation stopped by Dunkin Donuts to receive a free donut. These consumers devoured the sticky treats without thinking about the history or science behind the donut. But, the history and science, particularly physics, is interesting. So, I will now discuss the connection between donuts and physics. The Dutch brought the idea of deep-fried balls of dough over to the western hemisphere. Originally, the dough balls were spherical, solid,
  6. Where are atomic clocks used?

    Sounds like a very interesting summer job
  8. Population concerns on Earth are leading scientists to inquire whether colonizing Mars is possible. As of now, over 78,000 people have applied to leave Earth forever and live on Mars. Mars One, a nonprofit organization, is sponsoring the colonization with a take-off date sometime in 2023. Out of the applicant pool, four will be chosen to send first to Mars. The first four will lay the groundwork for a permanent colony. Two years after the first four land, Mars One would send up more people to the colony. With the application process underway, it seems as though scientists have discovered ways
  9. Hmm. The use of physics to shoplift, I wonder why we don't learn this in class...
  10. Pale people of the world, beware of the shining, warm sunlight! UV radiation, with a shorter wavelength than visible light, is absorbed by skin causing a sunburn and long-term skin damage. The Earth's atmosphere filters the majority of UV rays before they reach pasty humans; however, UV rays still penetrate the atmosphere. Exposure to UV radiation changes based upon altitude, distance from the equator, time of day, season and amount of cloud cover. At noon, with the sun high in the sky, sunscreen is heavily advised. How does sunscreen protect people from UV radiation? Sunscreen includes org
  11. This is a great post! I agree that this is the hardest AP I have taken also.
  12. I definitely formed some college study habits while taking physics this year
  13. As senior year comes to a close, brain space previously reserved for memorizing lists of vocab or challenging physics concepts has been filled with plots for senior pranks, senior runs, and so on. As of now, our senior runs have been quite brief, but I remember the senior runs of the past being both long and successful. As a freshman, I remember being caught in the hallway as I heard the shouts and footsteps of hundreds of seniors coming my way. Senior runs, or more like senior stampedes, can be heard from far away which is good so that small, tiny freshmen have time to hide in the bathrooms a
  14. I agree with Dave. The Kerbal Space Program is really cool and I have definitely learned a lot from it, but other options would be nice also.
