Yangian

Alright, kiddo, let's talk about something called a yangian. It's a really cool concept in math and physics that helps us understand how things move and change over time.

Now, think of a puzzle with lots of pieces that all fit together in a certain way. When you move one piece, it can cause all the other pieces to move too. This is sort of like what happens in nature, with particles and energy interacting and affecting each other.

The yangian is a way for scientists to better understand these interactions, by studying something called symmetries. Symmetries are like patterns or rules that tell us how things should behave.

The yangian specifically looks at symmetries in something called a quantum (or very tiny) system. It helps scientists predict how things like particles and fields will interact with each other, and how they'll change over time.

So, in short, the yangian is a really useful tool for scientists trying to understand how things move and change in the quantum world. It's like a map or guide that helps them see patterns and predict what will happen next. Cool, huh?
