What a tree rings sound like when put on a record player

Tree stumps look kind of like a record, right? So what would they sound like if played. It makes a tortured, yet beautiful sound of piano keys as it spins, using optics instead of a needle to read the notes:

The rings of a trunk reveal the age of the tree, and environmental conditions like rainfall levels, disease, and even forest fires. Light-colored rings indicate growth spurts, while darker marks show times of a slowdown.

Each slice is unique — a glimpse into the story of a tree’s past. Bartholomäus Traubeck wondered what story those trees would tell. So he created equipment that could translate those rings into music on a record player. But instead of a needle, an optical sensor reads the wood’s color and texture. Then, algorithms convert those variations into notes on a scale, which is mapped to a piano synthesizer and played.

How Spongebob predicted meme culture

There’s a reason everyone at my University dorm fought tooth and nail to get Nickelodeon, and by extension Spongebob on our TV. It wasn’t because Spongebob is a window that we look back on a carefree time when we weren’t bogged down by overwhelming existential dread (lol), but because even now it’s genuinely funny, extremely well written, and has some important morals that still ring true today.

Also the video above by Quinton reviews is pretty good.

How to reboot civilisation after an apocalypse 

In this interesting TEDxTalk, science journalist Lewis Dartnell gives a talk on just how we would make sure humanity survives if a large apocalypse were to hit earth. And that’s by preserving knowledge.

I had a conversation with Wayne and some friends about this very same concept and what we would do in this scenario (Assuming that I don’t need shelter from zombies/nuclear fallout .etc). What I said was exactly what is said in this video: I would work to preserve the sum total of human knowledge. I just wish I had the apocalypse Kindle that is in this video to back up my argument.

As for what I would save… that is a tricky question. I’m a man who loves science, so my kneejerk reaction is to save as much science and maths information as possible. But I feel that a lot of our discoveries, while very important, can be done again. We can figure out the planets and their orbits again. We can learn that the Mitochondria is the powerhouse of the cell. Calculus can be reinvented.

What I would try and preserve would be things for humanity to survive long enough to rediscover these sciences, like medical textbooks, first aid guides, how to hunt, how to forge metals. I would also try and store as much of human history as I could. I believe that as a species we have done both incredible and horrible things, and that they need to be preserved forever. And of course, a printing press, so that my Kindle is not the only Book of Knowledge to exist.
