# Bohmian Rhapsody

Is this the real world? Is this just fantasy?
Heisenberg’s theory is divorced from reality
Open your eyes, look into to the quantum sea

I’m just a boson, who needs locality
Because my $\Psi$ tells me where to go, pushing me to and fro
Any way my path goes, it’s all really hap’ning to me, to me Continue reading “Bohmian Rhapsody”

# Did Heisenberg have a soul?

In 1955, Werner Heisenberg traveled to Scotland to give a series of lectures which were later published as the book Physics and Philosophy (both originally in English). In it, Heisenberg lays out a (dare I say surprisingly?) cogent exposition and defense of  The Copenhagen Interpretation (a term which he coined in this work, although it turns out it’s really just his interpretation and there are a number of different Copenhagen-type interpretations) and discusses a number of related issues. The book is interesting both as a historical artifact giving insight into the thoughts of one of the founders of quantum mechanics, and as a highly accessible (if biased) introduction to issues in the ontology/epistemology of modern physics. It made me feel things, so I’m going to write a second post with various scattered reactions; but first, here’s a brief summary/background of the work, along with one of those scatterred reactions. The teaser: according to Wikipedia, Heisenberg was a devout Lutheran; did he believe in the soul, and if so, is the existence/justification of a soul central to his interpretation?

# Water all the way down

## Let’s get to it

I anticipate that three things will be true about this blog:

1. I will write about, among other things, the foundations of physics.
2. My parents, who don’t know much about the foundations of physics, will probably read it (Hi Mom!)
3. If anybody who knows anything about the foundations of physics reads it, I will never get a job because of the silly things I expect I will say.

As (a) a consequence, (b) in the interest of miseducating the general public, and (c) because I feel the need for some sort of inaugural blog post acknowledging its own existence, insofar as it is distinguished by being First, let’s start off with an introduction to the foundations of physics.
