Why are some equations deemed beautiful? What is the difference between them and others?

[Tormod]

Good question. I just recommended a book about that in the Christmas book thread.

Here is a review of that book:

I think the "beuty" is related to "simplicity". It is all about finding the simplest way to explain something, and then wrap it all up in the shortest equation possible. Like E=mc2...

Does it usually work out that the simplest equations are more often right?

[Tormod]

They would at least have less room for error since there would be fewer variables which could screw up the results.

But of course - any equation is based on assumptions that other equations are right. The entire mathematical language we use is based on basic assumptions which might turn out to be wrong...so I think simplicity rules because - that's the way it is.

What assumptions? Could these assumptions be applied to the thread in Philosophy and Humanities > Philosophy of Science - physics eventually gets down to assumption and acceptance?
