Chad Orzel is one of the Science Blogs crew and his dog has a bad habit of reading his Quantum Mechanics books in a vain attempt to get more treats:
“Therefore, it’s possible that you dropped steak on the floor. And according to Everett’s Many Worlds Interpretation of quantum mechanics, that means that you did drop steak on the floor. Which means I just need to find it.”
“Well, technically, what the Many Worlds interpreation says is that there’s some branch of the unitarily evolving wavefunction of the universe in which I dropped steak on the floor.”
“Right, so I just need to find the unitary whatsis.”
“The thing is, though, we can only perceive one branch of the wavefunction.”
“Maybe you can only perceive one branch. I have a very good nose. I can sniff into extra dimensions.”
It doesn’t take much reading of Quantum Mechanics to make my head hurt so reading explanations taken down to the level of a dog’s understanding helps to get the head wrapped around the concepts involved. In short, while Everett’s Many Worlds Interpretation of Quantum Mechanics is pretty cool it’s also of little use to those of us who’d like to change which reality we’re dealing with.


















I think quantum mechanics isn’t always properly explained, and lecturers themselves aren’t prepared to admit what they don’t know. Also because you’re dealing with the most primary rules of all, the question ‘why?’ sometimes has no answer (as you’re at the top of our percieved pyrimid of reason), all we know is what and how. Much like the rules behind Langton’s ant - we predict the consequence but cant explain why the rules are there.
It almost feels like the foundations that underpin everything have no reason to exist themselves - and no reason to stay as they are or even exist for the next moment
