…Will come one day.
In the mean time, go over and play Meqanic reborn on the web: https://meqanic.com/web/
And enjoy these old pictures and clippings I found on my hard drive.
The original icon for the Meqanic app.
The original name for Meqanic was “Weird” (file says June 2013).
A shirt I never made.
Way back when, still a PostDoc, I began outlining a children’s book on quantum physics. And – in a way – I’m finally close to finishing it. The twist is that I didn’t actually write the book I had wanted to. Something intervened.
The iPhone came out. And then the iPad.
The book turned into an app turned into a game. It is a puzzle game, sort of, like Tetris or Sodoku. The game in no way mentions or refers to quantum. The casual user would never know. It’s just a game that people (I hope) will just want to play. I call it “gorilla education”. I’m really not sure yet if it will teach anything to anyone – or if the game is even any good – but the only way to know is to experiment.
The goal of the game is straight-forward: make the current view match the target view by adding blocks to wires. The way it’s shown in the game – the “views” – are via what I call a P-matrix (see, e.g., New J. Phys. 14 053028 (2012)). The way to visualize an (exponentially growing) quantum state has been another bit of (failed) side research of mine.
The universe.
