How the Conservatives Saved Physics, by Lubos Motl

Filed under: Uncategorized — rrtucci @ 2:52 am

A friend of mine that works in the publishing industry has informed me that Lubos Motl is currently putting the finishing touches on a book that he has written entitled: “How the Conservatives Saved Physics”. Two possible covers have been leaked to the press. Here they are:


Lubos Motl believes that quantum computers are allowed by the laws of physics, and that they will be built someday. He considers them an interesting engineering problem, but not as fundamental as his beloved String Theory. He has a very low opinion of what he calls anti-quantum zealots, such as Many-World and QBism advocates. I don’t agree with Lubos about many things, but I agree with him on everything I’ve said so far.

Note that QBism and Quantum Bayesian Networks are very different animals. QB nets are just a graphical way of representing quantum density matrices. They are not a new interpretation of quantum mechanics like QBism claims to be.


  1. In case you are new to this blog and can’t tell when I’m joking, Lubos isn’t really writing a book with this title.

  2. I am writing it! Who told you that I wasn’t? The cover is different, however. Yours is fake.
