This week we learned a lot about waves and there are waves all over the world. Not only speed waves, we encounter so many waves in our daily lives. For example, while i was microwaving, i thought about waves because its in fact microWAVE. As waves go through the food, it moves the particles and that makes the food warm up (isnt that right, doc?). We also use waves to transmit the radiowaves and so on. But those are all invisible waves so we dont really notice them around. We notice more of ocean waves and stuff. Waves at the beach is the most commonly known example of a wave. We like to go surf and bodyboard when theres a high amplitude. However, when it has high amplitudes and higher frequency, it is dangerous. If you arent good at swimming like i am and go beach on those days, you have made a fatal error. Waves are fearlful though depending on what kind, it is quite useful. some light waves are pretty dangerous too. Some of them can cause skin cancer. Waves are seriouslly all over the world without any exceptions. Its important to learn stuff like that, right doc?

While i was spinning my pen around (because i was bored while filing out informations for my college apps), i noticed that there was a spring inside a pen (i knew it existed but i didnt really care back then). As i observed that spring, i began to learn the mechanics of it. I was impressed how clever they made that thing. As i was impressed, and before i even knew it, i started to wonder if i can figure out the spring constants and some mechanics that actually enables the pen to work. i designed a experiment just like the lab. Except i didnt have the exact weight for 5g~100g objects, i couldnt really do the same thing as a lab. As a matter of fact, i ruined a spring by putting too much weight on it. It was great how i couldnt really just that pen anymore but its alright because i actually was thinking about physics while i was playing around.
