  1. Singing Glasses

    Last weekend at an honors interview at Roberts, I got to take a look in some of their physics labs. they had some fun things set up for us to check out. One thing was in a section called "physics and music". Sounds perfect for me, right? They had a bunch of wine glasses filled with different amounts of water. When you dipped your finger in some water and rubbed it around the edge of the glass, a specific note could be heard. However, if your finger isn't wet, it doesn't work. Why? Turns out, it is because there is too much friction between the finger and the glass when the finger is dry. When the finger is wet, there is minimal friction, which allows the glass to vibrate, which produces the note. The amount of water in the glass determines how high or low pitched the note is. If you try this experiment, try placing a ping pong ball in the glass. The ping pong ball will make the vibrations visible because it will move on top of the water as the glass vibrates.
  2. The Year in Review So Far

    I relate to this. Let's make our last semester a good one!
  3. Eardrum vs Sound

    I prefer not to use earbuds when listening to music, I have some solid speakers in my room and I like that a lot better.
  4. The Not So Millennium Falcon

    Animals are crazy!
  5. Jumping Rope

    I used to jump rope all the time when I was in recess at school. It actually took me a long time to learn, which is why all my friends were boys in first grade!
  6. Second Quarter

    We're halfway thereeee! (Cue the Big Time Rush song! ...anybody?... no?... ok.)
  7. Disney Pixar's Up: Exposed

    Wow... definitely not the cheapest way to travel!
  8. Why do Bananas Have a Curve?

    It's amazing that I never would have thought about this... but now I know!
  9. Guitar Strings

    Didn't know you played guitar! I know for the violin you are supposed to restring it more often than I ever do. Three out of the four strings on the instrument are the same strings that were on it when I bought it years ago! The E string (the highest string on a violin) broke twice though so that has obviously been replaced.
  10. not so on Top of this

    It's amazing you even remember this activity! Impressive Also I love the pun
  11. Quarter 2

    Good job guys! We made it through half of our senior year! Not only that, but we also made it through mechanics, and now it's time for electricity and magnetism. For me, this quarter is when I started to figure things out, but I also had added challenges. I started to get the hang of the time management involved with this class. I was able to start planning better what I would get done when, as well as figuring things out with my partner in class. Of course, I am not perfect yet, as we can see from the fact that I have done most of my blogs this week. Next quarter, I will definitely try to stay on top of doing one a week, and I mean it this time! Honestly, these are fun for me because I also enjoy writing. I'm hoping the rest of the year will be a little easier for me because some of the added stresses are going away. This quarter was also all about applying to colleges. I applied to 8 schools and have gotten acceptance letters from 5 of them. I'm just waiting for 3 that I will hear from in March because I could not apply early action. I've also been invited to participate in multiple honors programs, and a couple of them required me to miss a day of school or a couple rehearsals to come interview. At this point, these things are finishing up, and this semester I will be able to focus more on high school!
  12. The Northern Lights

    I have always wanted to see the northern lights, or Aurora Borealis. I've dreamed of travelling somewhere like Alaska or Finland to see them. In fact, there is a hotel in Finland with glass igloos so the vacationers can see the northern lights from their room. How cool is that?! Aurora Borealis mainly occur in high longitudes, but what exactly causes them? Turns out, it's from charged particles from the sun being expelled into space. The particles then come in contact with Earth's magnetic field. Then the Earth directs the charge to the poles and they collide with gas particles. Here's the hotel with glass igloos too... And more northern lights pictures because I love them!
  13. What's at the End of a Rainbow?

    Here's a riddle for you guys: what's at the end of a rainbow? I'll get back to that at the end. So, rainbows. As we all probably know, rainbows are not objects that can be approached. They are an optical illusion caused by water droplets viewed a certain angle from a source of light, most likely the sun. There may appear to be a person under a rainbow from where you are observing it, but that person just sees the rainbow from a different distance. A rainbow is caused by light being refracted in a droplet of water like rain or mist. It is reflected inside in the back of the droplet, then refracted again. In a primary rainbow, the color red is on the outside, and violet is on the inside, but in a double rainbow, the colors are reversed in the second rainbow. There really aren't any distinct bands in a rainbow, they are a continuous spectrum of color. Any bands we see are a result of human color vision. Anyway, back to my first question. What's at the end of a rainbow? And the answer is... a W.
  14. The Physics of Dance

    I'll let you in on a little secret: I am a terrible dancer. Dancing has always been my weakness when it comes to doing shows, and I typically try to make up for it with singing and acting. When I see good dancers do it so effortlessly, I am extremely jealous. This crossed my mind because I actually have to go to dance rehearsal soon (and this is where I say everyone please come to IHS's production of The Music Man March 15-18). Anyway, time for the physics. As you have probably guessed, there is a lot of physics involved with dancing. When dancing and moving in a constant direction, you are creating momentum. The momentum is determined by your mass and how fast you're moving. If you develop more strength and can move more quickly, you will increase your momentum. When it comes to dance turns, torque is very important. For example, in some turns, you extend and retract your leg, which changes your rotational inertia. When the leg is extended, rotational inertia increases and you slow down in your spin. When the leg is retracted, rotational inertia decreases and your spin gets faster. Unfortunately, understanding the physics does not make me any more graceful or a better dancer.
  15. Archery: The Physics of the Bow

    Woah! Erika's doing a blog post that's not music related, crazy! Fun fact, I used to take archery, and I want to start again. With my favorite part of the year in gym approaching, I'd like to talk about some of the physics involved in archery, specifically the bow. The most important part is the force and energy exerted when pulling back the arrow and letting it go. Unlike what some may think, when pulling the arrow back, you are not stretching the string. What you are actually doing is changing the shape of the bow, giving it potential energy. This allows the bow to act as a spring. If you do more work pulling back the arrow, more energy can be transferred to the arrow in motion. This is why many people prefer compound bows. The pulleys allow for the person to do more work with less physical effort.
