Birthday!

This past week was my mother's birthday. Therefore on the night of her birthday, my father purchased a strawberry cake for her. As we were getting ready to sing "Happy Birthday" to her and light the candles, I remembered the lesson about unpolarized and polarized light. We learned in physics that the light exhibited from the candles was unpolarized light because the electrons in the light vibrate across different and random planes. Polarized light would have the electrons reverberating through a sequential and organized pattern. Even though the human eye cannot distinguish between polarized and unpolarized light, we know this fact to be true. The candles which my mother quickly blew out were emanating unpolarized light.

Electricity Converters

While we were learning about electric converters and how they are often used in cities to step down power to the usable 120V wattage, this reminded me once again about my trip to Vietnam. Driving through the city, I was always amazed by how many wires each individual pole was able to hold up, yet I did not see many of the electrical boxes I was used to seeing sitting on the top of each pole like I do at home. This was probably because I did not know what these boxes were for or what they did. An electrical converter found at the top of the electrical pole usually steps down the energy found in wires so that it can power our appliances in the home. I do not know the Vietnamese system of electrical power, but what I do know is that, in even the developed cities which we often made our way through, their electrical poles are so inundated with individual electrical wire, that it indeed looks like an accident waiting to happen.

Magnets

Every day, I often find myself running to the fridge to gorge on food. I don't know where it all goes! As I approached my refrigerator after spending some time preparing for this weeks test, I realized that my fridge is literally plastered with magnets. The forces that magnets exert on one another are similar to electrical forces, they repel and attract each other without touching. *Like poles repel each other; opposite poles attract* My entire fridge is a huge magnet attracting other magnets! Do not bring any types of electrical devices near my fridge because all of the magnets sitting on top of it, could damage your devices!

Physics?

On the first day of school when I entered into the physics classroom, I looked around and thought to myself, "Finally! This is the last science class I will ever take at Iolani!" My whole attitude towards science has since changed. I now look forward and enjoy coming to class to learn more about "the world around me" and being able to apply it to physics. The class seems to come much easier to me than in any of the other science classes taught here at Iolani because rather than focusing heavily on the math aspect of physics, we look more toward the concept. My goal for the next quarter in physics would be to possibly improve my quiz grade and also bring up my project grades, as they both tended to bring my grade average down. If I were evaluate my effort and the amount of time which I put into my physics work, I would probably grade myself on a 9/10 scale because while I do put out a good amount of work, by giving just that little extra of energy, there are still some improvements which can be made.
