I’d known a bit about audible sounds before hand, though not much more than “humans hearing diminishes with age” and “dogs can hear frequencies human’s can’t.” It was fascinating to discover more about hertzs. I was especially impressed with the fact that bass guitars, which are at 41 hz, aren’t actually audible, but rather what we hear is the “echo” of their oscillation.

I think I want to know more about sound waves and oscillation. I never really learned about it above some basic knowledge back in high school that by now has been supplanted by other lessons.

Out of the topics touched on in class, I’m not sure I fully understood how vinyls were recorded. Was the wax disc that the needle carved then used as a mold, or is vinyl actually a hardened wax-like substance? interesting either way.

I think the thesis I stated may be something I’ll explore on my own time. “Overabundance in choices creates simplicity in desire.” An interesting hypothesis, if I may toot my own horn.

Until next Wednesday, stay dry and have a good Labor Day!

Thought of the day: If it is interesting, it’s worth pursuing. if it is helpful, it is worth doing.
