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.

It's NOT yet, I am process of making it. So as of now there is only a newsletter for announcing it. (It will be no-registration, no-ad, though.)

Hehe, I gathered that from going through the newsletter sign-up process, but it does make that unclear. Perhaps a statement as to when you expect the first draft of the game to be up would make it clearer.

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.

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.

Emotional attachment it one thing. But pilot wave stuff does not explain anything, adds complexity and makes problem for more complicated systems that "a single particle in spatial representation". I do know professional physicist who prefer Bohmian interpretation (but most I know are in some version of Many Worlds or Quantum Bayesianism). The thing is whether a choice is made for purity or because of adherence to classical physics.

I added "coming soon" - does it look explicit enough by now?

"when" - it's a tricky question, I would love to know!

This article seems to be alluding to the likelihood of parallel universes and multiple outcomes of any moment, implications of which are too staggering to ponder and rarely given attention.

It is indeed glossing over the most intriguing consequence of the paper, which is evidence for parallel universes. David Deutsch's mesmerizing book, The Beginning of Infinity, describes the barely comprehensible nature of this reality and why it must be true.

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.

It's not remotely clear, because although this concept explains the result it does not uniquely explain it, and it does not make predictions that allow it to be distinguished from many of the other potential explanations.

I'm well aware of the adoption rates of Bohmian Mechanics. What I object to is dismissing it as being the product of emotions and not differing ideas about the universe. On that graph 42% went to the Copenhagen Interpretation whose fans are just as emotional as Bohm's.

Feel free to reject BM on technical merit, really, I couldn't care less.

As an aside, the graph is a little funky since Bohmian Mechanics is not an interpretation of QM but a reformulation of it.

Quantum mechanics is weird only because we don't learn statistics in high school (well I didn't anyway), and we can't come up with good real-life analogies for quantum interactions.

For example, the twin-slit experiment used to illustrate collapsing the wave function (a single electron fired through 2 slits will show a wave interference pattern on the wall, but the pattern disappears if you find out which slit the electron passed through) is portrayed by physicists as obscure, weird, arcane, or even as indecipherable devil magic which us mere mortals can never strive to intuitively understand beyond pulling out a PDE.

This flat-out isn't true, and here is my analogy for the 2x slit experiment in real life (using trashy fiction):

The electron is an young impressionable female, slit A is the handsome vampire, and slit B is the wild werewolf. Until absolutely forced to pick one of the slits, the electron sort of strings both slits along (and the result is a lot of interference which, in the literary world, we call plot). But, when the reader looks at the end, she (the electron) inevitable picks one of the slits. Summed over all the trashy romance fiction out there, one gets the feeling it's the same damn electron and two slits everywhere, yet she is clearly making different decisions each time.
