Why Is Quantum Mechanics So Difficult? - Comments

Yes, learn the math and see the beauty in full.

Didnt Hawking famously say - every equation he puts in a book takes X amount of sales off.

Paraphrased.

That's valid for popular science books. For textbooks on physics the opposite is true: The more formulae the author offers, the more steps are made explicit in a derivation, for the student the more simple it is to follow and understand the argument ;-).

There's nothing beautiful about having to observe everything projected onto a random choice among real-valued probabilities. But that's how the actual world works, and that's the mystery the public wants to understand.

Define understand and how you know you understand something.

Personally I think the word understand is vague and rather useless.

Define understand and how you know you understand something.

As far as explaining physics to the public, I'd define understanding as a form of economic utility. Math is the only reliable way to grapple with the "Big Questions". If people are to expend time, money, and effort to learn mathematical physics, they expect to see how that's done. If that's not what they see promoted, they'll take the low road and learn nothing or less.

Explaining equations in plain English does not mean there are no more equations. It means that the equations are written to be teaching tools themselves, rather than merely something to learn. I never thought it possible, but apparently they've been there for quite a while, hidden beneath a pile of Google trolls, and now the trolls have disappeared. (Obama's parting gift?) Here's an example:

I suppose you think this math is ugly?

Why should this be ugly?
