In one sensory incident, I was walking out of the library, and I sensed the inductive anti-theft device. I have walked in and out of dozens of libraries hundreds of times, and never once have I thought about the magnetic fields passed through me to prevent me from stealing a book. I have been intellectually aware of the mechanism, but never paid attention until now. Another time I opened a can of cat food for my girlfriend’s pets, and I sensed the electric motor running. My hand was about six inches away from the electric can opener, and I was able to sense where the motor was inside of the assembly. Again it brought my attention to a magnetic source that I understood intellectually, but would have otherwise been unaware of. I feel I am one step closer to fully grokking the reality I inhabit.
