I was hunting around on the internet looking at some different articles to pass time, to fall asleep.  I came across a story about robotic jellyfish that move autonomously through the water, and one was made to move in the air. The article doesn't say much about these robots. But looking at the video of them you can start to imagine the physics and mechanics of how the robotic jellyfish work. You can see how the tentacles are connected to a central body, that makes a pumping motion. The jellyfish can communicate with one another using short-range radio and LEDs.

The article is really just inspiring because it shows the capabilities of math and science, and reminds me why I want to be an engineer.
