By now you're probably aware there's a new Ant-Man movie on the way in the Marvel Cinematic Universe called Quantumania. In the MCU and other science fiction media, the word "quantum" gets thrown around quite a bit. 

Why can you teleport? Quantum physics. Why can you shrink to the size of an atom? Quantum mechanics. Why can you walk through walls or travel the multiverse or bring someone back from the dead? Quantum entanglement. Quantum computing. Quantum. Quantum. Quantum. 

At this point the word "quantum" paired with just about any other word is a stand-in for something like "science magic". It's the label slapped on a bit of plot to explain why the protagonist can do the thing. But this type of slapdash explanation isn't relegated to the silver screen. 

Films like 'What the BLEEP do we know?' and books like 'The Secret' all maintain that our thoughts affect the world around us. The phrase "thoughts are things" gets bandied about. Oftentimes this is called the "Law of Attraction", or whatever you think about most often tends to show up in your life. These days other buzzwords float around and occupy similar space. Affirmations. Manifestation. And why does any of this work? Quantum physics. Quantum mechanics. Quantum entanglement. Quantum. Quantum. Quantum. 

I'm no physicist, but I know enough about marketing to know that the same word cannot possibly mean all of these things at the same time. Or could it? I'm no physicist after all. Perhaps it can? I wanted to ask an expert. 

Jed Buchwald studied physics and science history at Princeton University, and earned a PhD from Harvard in 1974. He taught at the University of Toronto for two decades, where he spent a year as the director of that university's Institute for the History and Philosophy of Science and Technology. Buchwald then became the director of the Dibner Institute for the History of Science and Technology and the Bern Dibner Professor of the History of Science at the Massachusetts Institute of Technology before joining Caltech in 2001. He has authored or co-authored six books in the history of science and, more recently, on the decipherment of Egyptian hieroglyphics. He edits or co-edits three book series for Springer, one for MIT, and two journals. Buchwald is a member of the American Philosophical Society, a member of the International Academy of the History of Science, and a fellow of the American Association for the Advancement of Science. He was also a MacArthur Fellow (1995) and a Killam Fellow (1990–1991).
