A good book to read on this topic is David Bodanis's E=mc^2,

"A biography of the world's most famous equation"

It's not just another Einstein book. It's actually about just the equation and its life.

The author gives examples of how printing houses using different equation notation were like Microsoft, driving out the competition for the standard.

All manner of symbols were used for math, some examples:

e================== mc^2

e || mc^2

e -----------> mc^2

e .aequs. mc^2

e ][ mc^2

Anyway, yes equations "can" be nice too look at in mainstream media.

Only to show a simple proof or to inspire a reader into further learning.

Of course, if it looks like spaghetti to the masses, then maybe the publisher went too far :P

Regardless, wasn't Einstein known for explaining complex concepts in terms that even the non-scholastic could understand?

Don't think he used any equations to describe relativity to them.

In fact, Einstein was not even a good Mathematician, iirc.
