it sucks knowing that i’ll always be the one who cares more, loves more, i’ll always be the one willing to walk for miles yet for me, they wouldn’t take two steps.
It truly fucking sucks.
What I HATE about the new Star Wars movie is that they have these small creatures called “porgs”. I have called my corgi “porgs” FOR FOUR YEARS NOW. 😡
Stressed to all hell between personal life and multiple things with school. It’s also annoying I feel as though my classmates are all buddy buddy and I’m just in the shadows.
😒
Can someone tell me about a Scorpio-Sagittarius cusp baby? Curious because I have more traits of a Scorpio than a Sagittarius but I’m truly a Sagittarius.

like you can tell me all you want how the sound is stored in the grooves but fucking H O W
HOW DOES THAT GET INTO THE NEEDLE
HOW ARE THE VIBRATIONS TURNED INTO MUSIC THAT YOU CAN HEAR???
H O W
The vibrations aren’t “turned into” music, they are music. When vibrations occur inside your inner ear, your brain processes this as sound.
The grooves in a record are an analogy for these vibrations, a method of remembering them so that they can be recreated later on.
Put your hand on a speaker while loud music is playing and you’ll feel the vibrations. Those are exactly the same vibrations happening inside your ear when you hear the music.
But how do you capture that?
Take a surface that vibrates strongly when a sound is played, like the skin of a drumhead for example. Connect that surface to a little tool - when sound causes the surface to vibrate, the tool digs a little bit into some wax, leaving behind a pattern that matches - in proportion - the vibrations of the surface caused by the sound. This is your analogy (hence: analog music).
Now, when there’s no sound playing, you run that little tool back over the pattern. This causes the skin to vibrate again, this time in response to the tool running over the pattern instead of because of an external sound. The vibrations should match, proportionally, the original vibrations of the music.. and thus these new vibrations, if you were to amplify them, would be a recreation or “recording” of the original music.
That’s oversimplified of course and things have changed a lot since the days of wax, but that is very basically how the process of recording music worked at first, and the general idea of how sound gets from a groove in a record into your brain.

Thank you Science side of tumblr
I hugely appreciate people taking to the time explain stuff like this, as it helps put an end to the “wow, science is magic!” trope that’s become far too common.
