An Isomorphism is the mathematical concept that generalizes ‘equality’.   ‘Equality’ is just as it was presented in middle school, there is an equal sign and an expression on each side. Like so: 3x = y This means that 3x is precisely equal to y. Anywhere you see 3x you can substitute y, and vice versa.  But this type of equality, while intuitive, is constraining. In reality, we see things that are the ‘same’, but not precisely. You might really want to say that these things are equal, but they don’t satisfy our intuitive definition, ie. you can’t switch one out for the other willy-nilly. For example, the Golden Gate Bridge in San Francisco and the George Washington Bridge in New York. These are both clearly bridges, so they are the ‘same’ in some sense, but not exactly. You can’t magically change the Golden Gate Bridge to the George Washington Bridge, they were specifically designed to be built in one place.  So can we capture this equivalence? What does it actually mean to be a bri
