Callahan

just finished reading a fascinating book: "Exploring the electromagnetic spectrum", by Philip Callahan.
wow! i've been waiting for something like this for a long time. i'd say that the quote that best sums up the book and callahan's central theme is "everything is connected to evertyhing else, especially by the electromagnetic spectrum".

callahan says that form and frequency go together, which means that different life forms sense and emit different frequencies as a means of communication with their environment. that includes us. most of us are only aware of a small slice of the spectrum, in the visible and audio ranges. that's what we're tuned to, but there is so much more out there, which other forms of life can perceive (like dolphins with echolocation, and moths who are able to perceive ultraviolet radiation).

callahan's work covers many areas, but it always comes back to electromagnetic radiation as the form of communication between all things. one idea i find fascinating is that insect antennae are tuned to infrared radiation emitted from specific plants which the insects like to eat. related to this is that healthy plants will not attract insects and will not experience as much damage (just like healthy humans are less likely to become sick). i really want to learn more about this.

i just ordered another book by him called "Tuning into nature", which i can't wait to read.
check out his work!
