Tension Between Siblings

For the past couple days, I've been freaking out about what to do for my blog entry this week. Nothing struck me until just about an hour ago at dinner.


As you can see, my headphone cords are uneven. They are purposely like this so that you can put in one side, and pull the other side around the back of your head to keep the cords out of the way more. (If you don't get what I'm saying, track me down at school one day and ask. Haha.) Anyway, in the picture, the side I have in my ear is the shorter side. However, this style of headphones is unfortunately harder to share.

At dinner, my sister and I were eating and listening to music. I found that the earphone in my ear fell out much more often than my sister's. It occurred to me that it was because I had the shorter end.

I then proceeded to imagine the problem from our text book with the monkey holding onto a piece of string, but the lengths on either side of the monkey's hand were uneven. Our job was to find out which string had the higher tension, and it ended up that the shorter side had more tension because the angle the string made with the horizontal was greater.

Now I can explain why my headphone fell out more than the one I gave my sister. Unfortunately, only my classmates would understand. My family just gave me blank stares and absent-mindedly nodded their heads while I babbled. :]
