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.
No see we say science is magic because even with the knowledge that it’s pure physics, it is wonderful and awesome that this is how things are. It is magical that water freezes and gravity and matter even exist. Knowing exactly how they work doesn’t change that they’re amazing. The fact that sound vibrations can function this way makes sense yet it is still silly as hell. It’s so convenient that it sounds almost stupid but it’s just like that. It’s so great.
Did you guys know that the most recent version of sharks have fins that are kinda leg like and they like to walk up onto land?
no way i must have missed an update!
The Epaulette shark is only about 9 million years old as a species, making it the most recent branch in the shark family. And it is slowly but surely evolving into a land animal
You know what to do boys

More penta-beasts! Want to get a good grasp of the morphs going on in this planet. So sketched these out between coms! Info below!
TRYING TO GET A LAPTOP
HELLOW..... long story short I've been trying to save up to get something to play games on bc all I have is my dying switch. & my friend offered to sell me his nice gaming laptop for $600 & I need about $250 for it. So I'd really appreciate some commissions, art is my only source of income, & I'd really like to get myself something nice for once
Commission info below!! My turnaround time is about a week. I also have a ko-fi where I do sketch requests for $10 or more donations
& a few examples of my style (I can draw anything, furry/human/robot/etc)
tyty for reading
HELLOW AGAIN. Of course literally the morning after I get excited to get a laptop my car brakes start to give out. & long story short (again) my car is super old & fixing everything that needs fixed would destroy me financially, so I'm instead going to trade it in for a less shitty car, so commissions & donations are extra EXTRA appreciated now that I probably won't be getting the laptop for the foreseeable future. tyty for reading (again)
this tiktok was supposed to be about her husband quitting porn but all twitter's talking about is their baby on the phone

instead of watching the fast and furious you should be meditating on why the earth is so vast and curious
In 2016, a McDonald's Happy Meal/Nintendo cross-promotion in China included various Mario toys with the meals. The announcement on the McDonald's official Chinese website included a set of four animated GIFs showing the toys in action.

was goin thru the internet archive as you do and found these old pikmin renders in the process
Aliexe, a fallen god that used to go around and devour souls for the fun of it. Every where he went would bring a feeling of fear and anger on others. He loved seeing people fight each other for laughs. But his old enemy, Misiz, he's been fighting for years, finally took him down and now he's stuck with them. He's still a jerk but maybe with the help of Misiz and Grouch, he'll probably be...less of a jerk!
This is Grouch, Misiz's best pal! He flies around looking for stuff to collect and put in his tree somewhere in case they need it. Though some of it is junk but fun to play with. Him and Misiz are in their 40's but he acts old and tired...and grouchy. Misiz is energetic and loves helping others which is what he likes about Misiz. Grouch makes some mistakes here and there but he tries to be helpful when it's serious.
oh no, the old guy cartoon artists drawing chronically online grandkids were right
