EE Fun Facts
Ever made your physics teacher blind? I did.
I was talking to Chris about the experiment which involves me recording a screeching noise ("eeeeeee") for a period of time and I showed him a quick demo. A few seconds in and chris asks me to stop the sound - HE Cant SEE.
The class stood there super confused. Chris left. There are two ways to learn from this experience.
1. Don't play a sound of 880.01 Hz in class.
2. You now know how to get a free block in physics.
The class wanted to know what happened if I didn't take my medication so I showed them. The blindness was a migraine, the freezing was Parkinson's. Not going to do that again.
A Brief History of Time (doing my EE)
<I applied for the Norwegian Research Competition and apparently they said my physics EE was in the finalists? lol. When writing the application (it was in Norwegian), they asked for the title of work, and I thought the asked for job of the worker so I wrote 'student' >
Anyway, I am going to attempt to briefly explain my EE, in the most interesting, and least physicsy way possible.
Have you ever heard a race car driving past you? It makes a sound like “eeeeeeeeoowwwwww”. That changing sound you hear when a fast car moves past you happens because of a phenomenon called The Doppler Effect.
Now imagine the race car moving in a circle (don't have to imagine that, they do), you hear a sound like “eeeeooowww-eeeoowww-eeeooww” as it moves around. Easy to imagine. Now, what if the race car was moving in a circle on the tilted roof of the Oslo Opera House.(oh) How does the tilt (or the angle of the tilt) change the sound that you hear? Aha! Not as obvious. This situation is actually really similar to when a star moves around in a tilted orbit where we observe a change in the light produced by the star (instead of sound from a race car).
My research paper tries to determine the effect of the angle of the plane of rotation on the observed frequency shift of a wave source in circular motion.
I conducted an experiment by sticking a small speaker onto the blade of a fan. I played sounds of a constant frequency (“eeeeeeeee”) (I think I've gone blind again) while the fan was turned on so the blades rotated in circular motion. I changed the angle of the fan and recorded the change in sound each time. I found that that sound changes the most when the angle is 0 degrees, and not at all when the angle of the fan was 90 degrees. The frequency at any angle in between depends on several other factors that I discussed in my research paper.
Want to be a cool second year and do a physics EE
1. New EE ideas 101: I have recently gotten quite interested in trying to predict the angle of deflection of a table tennis ball based on how much force you spin it with. Sick if you plan to study the engineering option. Combines rotational motion with fluid dynamics.
2. Chris is an efficient beast. You WILL be made to finish your EE on time. (yes I suppose I do have a sort of beast like quality)
3. Here's mine. Thought Samples would be helpful. Don't know my grade yet though.
(Sorry had to take that out, don't want to be caught plagiarising your own work, Yash)
