    YAY DAVE! good for you for taking physics-C!
  4. ive always wanted to go bungee jumping! SO AWESOME!
  5. it always scares me to read about black holes! EEEK!

    It's All Over

    Well, this has been one year that I will never forget. At first i was really nervous to start physics, not knowing what to expect, if i could handle it or if it would just go over my head. Im not a huge math person but i have always enjoyed science and having a better understanding of the world around us. Luckily, this class became the perfect fit for me. Regents Physics quickly opened my eyes to a new world where EVERYTHING has an explanation and most things you cant understand on the first try. This class has taught me skills i can use in the future, from taking responsibility for my work, working in a group, studying and asking questions to better my understanding. Mr. Fullerton has been so incredibly helpful the whole year. I never felt uneasy having to ask lots of questions. He treated me as an adult and allowed me to learn my own lessons. He shaped me into a person that i am happy to be. After i studied really hard for the midterm and still felt discouraged about my performance, Mr. Fullerton gave me a call to tell me that i passed and how proud he was of me. It really brought up my confidence in this class and excited me for the second half of the year. His constant support and motivation are super helpful in a class like this. Also, his access to review tools and organization allow anyone to understand. Plus his books are awesome! My favorite project of the year was the Ipod Speakers. This is mainly because i learned so much about how sound waves work and it challenged me to push myself and not give up if i didnt understand right away. I am also glad that my eyes were open to the origins of the universe in video format, its quite entertaining. I am so glad that i had the confidence to make it through the year, to meet new people and to discover a new understanding of myself. Thank you for the lessons and for the memories. Good luck on finals! (Sorry Mr. Fullerton, i had to.)

    Energy Wooo

    THIS IS SO COOL BEN STEINER YOU ARE MY HERO
  8. this will be perfect for the future! definitely will help eliminate un-needed stress.
  9. i love reading reflections, this year seems like it went by really fast to me too

    Would you Rather....

    Would you rather.... get stepped on by an elephant? or get shot with a staple gun? Most definately, be stepped on by an elephant. You're probably saying to yourself; WHAT? I DONT WANT AN ELEPHANT STEPPING ON ME?! but trust me, you do. To find the pressure of one object onto another, you have to use the equation FORCE/AREA or F/A. So, if we have a 7000 Kg elephant stepping with a force of 68670 Newtons onto your hand, (F=mA) and the area of its foot is 0.18m^2, the amount of pressure would only be 382500p That may seem like a lot, but not compared to a staple gun, because its acceleration is much much higher, would have a greater force, and a smaller area, therefore making it extremely painful. This is why i don't play would you rather.

    Look Out Below!

    Recently in a perfomace I was in, the stage was designed to have many traps in the floor to allow characters to pop out for a suprise visit. These traps are fun for those who use them, but not so much when they break. During a scene when many characters are on stage dancing and jumping around, one of the characters landed with just enough force in just the right spot that the trap broke out from under him, dropping a whopping 10 inches before it became jammed, bruising the actors knees. Luckily there is a happy ending to this story unlike other disaster stories many actors have. (whoever starred in Spiderman the Musical probably has alot) But how could this happen? over the hours and hours of set up and design how could no one see this could happen? well, now they understand exactly why. about 12 hours after the event, the cast was brought back together into the theater to explain what happened, what went wrong and how they fixed it to ensure the safety of the cast for the rest of the run. As it turns out, one of the two-by-fours holding up the trap was split in half when the force of the actor was added to it. Before, when it was first built, the force of weight landing on the trap was designed to be pushed into a platform beneath the trap instead of being pushed directly to the floor. This probably has something to do with concurrent forces. The trap itself was designed to hold the least amount of weight it had to (the heaviest person in the show) but no one took into account the fact that as soon as someone jumps on it, the combination of gravity, mass, momentum and force all come into play at once. Plus, if a F=ma, and the actors acceleration was larger than walking (because he was jumping) then the forces all being put onto the trap at once caused the 2-by-4 to break. I think its really bizaar that one person was able to break a two by four directly in half just from jumping on it a little. I havent had a chance to go down and see exactly what they did to fix the problem. I think they used a variety of springs and such to allow for the energy to become transferred easily. As soon as i can find out i will do a little investigation and report back *No actors were harmed in the making of this blog post*
  12. Thats so cool! when i was really little my neighbors who were much older than me tricked me into thinking that bubbles were edible! i used to try to find edible bubbles whenever i went to the store! they were so mean...
  13. well, its a good thing i understand! and HOPEFULLY that will never happen to me
