Glasses Trick

Having glasses doesn't alway mean you can see your clearest. When I was younger my eye doctor always prescribes a lower but satisfying lens prescription since my eyes were on a roll by keep on worsening. So I could always handle a stronger lens than the one I currently had. Sometimes it was needed to see far thing. When it was about time to change to a stronger lens I would compensate by titling my glasses at an angle downwards and I could see far images clearer now. Can you figure out why this happens?

Why So Bright?

haha okay the picture was taken today and has NOTHING to do with the journal tonite. but i bet it caught your attention which ties into what my journal really is about. so this weekend at night we're driving around and i see this really fluorescent lighted sign. and i was like HEY! we talked about this in physics like how it has the frequency closest to the sun and they use it because it's the brightest and it can catch people's attentions. which is exactly what it did. before i thought the signs were just plain darkish yellow and was just nodding along during class but now i am a full fledged witness. yay =]

HOT HEADS =]

okay so on friday chad and i were standing in the long shave ice line and he was like whoa feel my hair. so i did and it was super hot. then i felt mines and it was hotter! well it's not til this week when we started talking about light that i realized why it was different if we were exposed to the same sun rays. there are two theories...well three after discussing it with him: 1) that i have darker hair because then my hair would have absorbed more light, thus making it hotter than his. 2) because i have more hair so more was absorbed. or 3) i have thicker hair because more surface area would have collected more light making my hair hotter. so what do you think?

WEEE!

How do you get a swing started without a push?
Well you make yourself look like an idiot and start pushing your legs
back and forth like a maniac. Seriously. This perpendicular force, torque, to the swing that you are sitting on makes it move which makes you move since you are on it! The continuous pumping of your legs makes the motion continuous also and thus a happy swing =]
A push doesn't help you get started either, you have to be held up and let go which turns potential (PE=mgh) energy to kinetic (1/2mvsquared) =] and your pumping keeps it going! woooo...now get on a swing and have some PHysics PHun! =P

Thing to think about: is it possible to go completely around the set if the bars allowed you to? well according to the guy on the left it is cause he did it(on a different swing set). HOW is it physically possible?

EW BIRD

okay so i am soo icked out by birds cause i think of all the germs and stuff thus i dont really want to take a picture of one so yeah. k so basically i was sitting by myself and theres the typical gray bird. so i hear this noise and i look at the bird and its shaking its feathers so its all puffed up now and the noise that i heard was the vibration and waves that the bird made by moving its feathers rapidly.

FRICTION!

so i went to a baby shower and they had the confetti on the table. so being me, i was playing with it and trying to pick them up with my finger and then they didn't so i thought that friction would help. so i rubbed it on the table and sure enough the thing stuck! yay! the opposite charges of my finger and the charged confetti makes them attract thus making my picking up successful!

Christmas...

How much would it suck if one of these lights went out? or do you think they used parallel circuited lights?

yeah i know...Christmas was a LONG time ago...sorta. but since we recently learned about circuits i decided to write about circuits that we use in real life. During Christmas, lights are put up. For instance, we have M&M lights that we put around the tree. But, when one goes out, the whole line goes out because they work on a series circuit, thus when one light doesnt work, the circuit is incomplete! intrigue...
