My subject choice - specific interests and backgrounds on subject:

My first subject choice that i submitted is chemistry, however I actually consider my second choice, physics, just as much as chemistry, since I am just interested in these two sciences more than any other subject, academically and personally too. My background on both physics and chemistry is the IB course, since I take both subjects, and also I started studying both subjects in 7th grade in my german school, which already gave me a base for the IB. Generally I definitely plan to expand my knowledge in those two sciences in all directions, since I personally feel like there are plenty of very interesting and significant topics to cover. I still don't quite know exactly what I will research for my extended essay specifically, however I had in mind to research something experimental, through trying out several common ways of for example an chemical reaction or physical process, and than based on that research I would like to create something new, like an improvement in an specific aspect, as in efficiency or environmental responsibility or anything like that.

Annoted Bibliography: "Re: Electromagnetic Speakers." Weblog comment. //Phyiscs Forum//. Jelsoft Enterprises Ltd, Apr. 2010. Web. 25 May 2011. .I used this site to basically get started in the field of speakers in relationship to electric magnetism, which I chose to be my topic. I am planning to get some basic insight from this site and to get some ideas about what closer aspects i could examine and what interesting things there are to know. I decided the source was somewhat reliable, and not bad for getting some ideas, because i read the blog before and i noticed that the majority of the comments are true.

"Figure 2-31. — Electromagnetic Speaker." //Repair and Maintenance Manuals - Integrated Publishing//. Tpub.com IntegratedPublishing. Web. 25 May 2011. .This website discusses the basic structure how a speaker is set up and what differences there can be between different sorts of speakers.

"Electromagnetic Speakers - DiyAudio." //DiyAudio//. Diyaudio. Web. 25 May 2011. .DIscussion of different speaker systems with remark to their different use and quality. This kind of sources will be part of my research to gain a wider range of understanding, which aspects are to consider about speakers
