Dot product Memes

The mathematical pun here is absolutely brilliant! The meme shows a Gram matrix (that blue rectangular monstrosity with all those vector dot products) arranged to look like the Swedish flag. The joke hinges on the fact that Jesus died on a cross (×), but in this alternate universe, he died on a dot product (·) instead. For the uninitiated math warriors, a dot product is an operation between vectors that gives you a scalar (single number), while a cross product gives you another vector. The Gram matrix shown here is entirely made of dot products between vectors v₁, v₂, etc. - making it the perfect mathematical crucifixion alternative! This is the kind of joke that would make a linear algebra professor snort coffee through their nose during office hours. Pure mathematical blasphemy!
