Hello my name is Joshua. My desire for learning physics stems from when i heard my friends sound system in his car, ported 15" that hit frequencies in the high 20s. I will never forget that awesome feeling of 27hz ripping through my body. Since then I have learned 12 volt theory and wiring, fluid dynamics relating to sub-woofers and enclosures, thermodynamics, signal generation and many other things. I have done industrial electrical in the oil patch, worked for a water transfer company in the oil-field using 600hp turbo diesel water pumps for pipelines, and now I'm experimenting with a 15k volt neon transformer and soon building a Tesla coil. I cant wait to get involved with this forum and start learning!
