I don’t think the general public is aware that, among theoretical physicists, the many-worlds interpretation (MWI) of quantum mechanics has become almost mainstream. (See, for example, this article by Max Tegmark.) This means, basically, that there are a large number of very, very smart people who take the idea of “other” universes seriously.
Maybe you are one of these people. Maybe you found this blog by googling “many worlds theory” and ended up here.
So, you ask, will this blog be devoted to the “Many Worlds Theory”? Yes and no. Yes, in the sense that I am a theoretical physicist, who has published work (such as this) on the weirdness of quantum mechanics. And yes, I will occasionally post on topics that relate to MWI (such as quantum interference, the philosophy of science, the existence of the universe, and whether Jet Li’s performance in The One was Oscar-worthy.)
But also, no, in the sense that I won’t always devote this blog to quantum physics. After all, the blog is called “Many Worlds Theory”, and not the arguably more correct many-worlds interpretation or Everett’s relative state formulation or universally-valid quantum mechanics. By “worlds” I mean not only parallel universes, but things that interest me. Sounds self-centered, right? Kinda personal?
Well, it is a blog. Isn’t it supposed to be personal?
My interests include, in no particular order: recreational mathematics, classical music, philosophy, politics, games of all kinds, science fiction, history, the ouvroir de littérature potentielle movement, movies, sports…(I’ll stop before this too closely resembles an ad on a dating website. Maybe it’s already too late for that. Anyway, I’m very happily married, thank you very much.)
Ultimately, this blog will be devoted to examining topics using a scientific mindset. Let’s get one thing clear from the start: I believe that it is only through science that we have learned anything about the world. My goal is to have this theme come through in all my posts. Sure, I might discuss the Higgs boson, the Heisenberg uncertainty principle, Berry’s geometric phase, or other physics stuff. But even when I discuss something non-scientific like Honey Boo Boo or Deepak Chopra or the Carolina Panthers or economics, I hope to stick to facts, and what can be demonstrated through logic. If I write a blog about how soccer is a boring sport, rest assured that I will give you reasons as to why it is boring, and cite the source(s) of my claims.
Of course, there is another universe in which this blog is devoted to how great soccer is.
Good thing we’re not in that universe.
