My callers fall into two very different categories. Some of them cherish the opportunity to talk to a physicist because one-to-one conversation is simply more efficient than Google. They can shoot up to 20 questions a minute, everything from: ‘How do we know quarks exist?’ to ‘Can atoms contain tiny universes?’ They’re normally young or middle-aged men who want to understand all the nerdy stuff but have no time to lose. That’s the minority.
The majority of my callers are the ones who seek advice for an idea they’ve tried to formalise, unsuccessfully, often for a long time. Many of them are retired or near retirement, typically with a background in engineering or a related industry. All of them are men. Many base their theories on images, downloaded or drawn by hand, embedded in long pamphlets. A few use basic equations. Some add videos or applets. Some work with 3D models of Styrofoam, cardboard or wires. The variety of their ideas is bewildering, but these callers have two things in common: they spend an extraordinary amount of time on their theories, and they are frustrated that nobody is interested.

What happens when an out of work theoretical physicist starts a business where anyone can call him on skype and ask questions for $50 / 20 minutes? Some really fascinating stuff. Mostly about how people absorb, or mis absorb, popular science.
We often forget that abstractions and models, are just that. Like maps, you file off all the interesting details to get a big picture. But a map of the US tells you very little about the stream in your back yard. The wildlife along it. When it floods. What vegetation grows because of that. The story is always deeper, more complicated, and more interesting the closer you look.
