Resumo - Abstract - The Science of Sound

Sound is energy created by vibration from a molecule, which causes the
other molecules nearby to vibrate as well. This energy travels trough waves, whose
characteristics determine the type of sound that is created. These characteristics are:
amplitude, that is directly proportional to the volume of the sound; and frequency,
that is related to how high or how low the sound is. Depending on the matter that the
sound is travelling trough, it can travel faster or slower. Since it is a transverse wave,
it can travel in any matter. It’s speed in air is about 1,120 feet per second. We only
hear a sound when the vibration reaches our eardrums, that vibrate as well, causing
small bones inside our ears to vibrate too, sending a message to our brain with the
characteristics of this sound. So, if nothing is around to hear the sound, it doesn’t exists.

Perfil de Maria Clara

My name is Maria Clara, I'm 20 years old and was born in Caicó, Rio Grande do Norte. At age 3, I moved with my family to Natal and since then we live in this beautiful city. I've been a vegetarian for 5 years now, and I'm a huge fan of cinema, specially movies by Quentin Tarantino, Lars Von Trier and Darren Aronofsky. In the first semester of 2010 I got into UFRN, studying Science and Technology and now, theoretically, I'm half way to graduation. Besides university, my other main occupations are my work as an Kung fu instructor, at the Lung Fu Kung Fu School, and as the lead guitarist of the thrash metal band Declite. I've been teaching at Lung Fu since 2008 and my sudents have between 4 and 64 years old. My time in Declite has been a little longer: we've been together since 2007 and we hope we can to record a demo cd with some of our original songs this year. Among our musical influences is the band Metallica, which will perform a concert in september here in Brasil, at the Rock in Rio festival. I'm very excited to go to this festival, not just because of the great bands, but also because I'd love to go to Rio de Janeiro.
