Personality type

ADMINISTRATOR
(Submissive Extrovert Concrete Thinker )

Like just 4% of the population you are an ADMINISTRATOR (SECT)--detail-oriented and organized. You're an extrovert, but you lack the over-aggressive tendencies of obnoxious "go-getters." Very nice. However, you probably like getting up in other people's business--living through them a little... dude, sometimes you just gotta let it ride. Don't be such a busy-body.

Anyway , you're an excellent manager, of both yourself and other people. That's because you prefer thinking concretely rather than creatively, and you'd rather follow what your mind tells you than your heart--people respect this, but it can make them mad when their appeals to love and kindness fall on deaf, deaf ears. Try to have a heart sometimes.

Well... www.thespark.com claims that I am this type of guy...

The essence of sound
(INTRODUCTION TO SYNTHESIZERS
by Thomas Kolb)

In order to fully understand how synthesizers work, we must first understand the physics behind the phenomena we perceive as "sound". So, what is a sound?

The air surrounding us consists of gas-particles. If you force a number of these particles to move, they will create a wave traveling from one particle through the next, in all directions away from the source. It's just like when you throw a stone into a pond - the water particles will create ripples or waves, moving away from the center.

Sound-waves are also initiated from a source, like a car engine, a slamming door or a finger plucking a guitar string. These ripples, or vibrations travel through the air and reach our ears, where they will set our eardrums into motion. This motion is in turn perceived by our brains and interpreted as a "sound".
