I never understand why the double slit experiment puzzles people. Is it not clear that we are dealing with particles guided by a wave? This is Bohm's theory and it works perfectly well for answering these questions.

Bohm theory is not well regarded by most of physicists, as it is a desperate try to use some intuitions from classic word. It helps with understanding double slit the same way as "God created it" helps with understanding universe - makes one calm and content. You may argue that Bohm theory works... but well, once you get other systems, you run into nasty complications and loose symmetries.

I think it's the argument for the hidden variable 'issue', mostly. It may be 'clear' but it's also philosophical at the same time.

I believe the Born Rule[1] may address some of these concerns.

You can reject Bohmians as being emotionally attached to their ideas, but you can also reject non-Bohmians for the same reason. Many (most?) who grasp quantum mechanics on any level feel they've climbed an important intellectual mountain and don't want to find out they discarded their intuition for no good reason.

An excellent book that addresses this topic is The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory by Brian Greene. You likely already knew it but consider this a reminder to actually read it if you haven't! It was bitrotting on my Kindle for long but once I started reading, it has got me hooked!

Quantum mechanics is not that hard, the only thing we lack is direct experience with it. So, I am developing http://quantumgame.io/ - a game governed by true quantum rules, yet accessible to a child.

I'd love to play it, but no way am I going to go through a registration process to play this.
