The Chinese Dumpling Theorem

A few months ago this kid in my linear algebra class started talking about the Chinese Dumpling Theorem. 

“I looked in the textbook, we’re going to use the Chinese Dumpling Theorem pretty soon.”

“I wonder if they’re going to teach the Chinese Dumpling Theorem this week.”

“I hope we get to do the Chinese Dumpling Theorem soon.”

He wouldn’t explain what it was, he just kept talking about it. For weeks. Now, a few classes ago, part of the lesson was the Rank-Nullity Theorem. For those of you that don’t know, the Rank-Nullity theorem is: for a transformation T from vector space V to vector space W,

dim( im (T) ) + dim ( ker (T) ) = dim (V).

When that goes up on the board the kid said, “that’s it! That’s the Chinese Dumpling Theorem!” Someone asked him why, and he said, “because it’s a dim sum!”

Needless to say we were Not Amused. 

THIS IS SO GOOD AAAAAAAAAAA
