Well…as you know, I get some weird thoughts when I’m out on the bike and I have had this one running through my head for a couple of weeks now…so, I thought I’d try to put it into words and just see what happens….the whole thing started with the realization or recognition that matter and energy are just two forms of the same thing and that everything that is living on the Earth comes from the photons that the sun emits….but, you know that…I hope…and those photons, when converted into matter by plants…are then used by me to make the chemical energy that I use to drive the bike…but, it doesn’t stop there….I find it kind of interesting how quickly this chemical energy can be changed into potential, kinetic, or heat energy while I’m on the ride. Ride to the top of the first hill, and the chemical energy has been converted into potential energy…you can’t see it or feel it but, at the top of the hill, the bike and I are full of this type of energy…and it is quickly released when I head down the next hill…..then the legs take over and the chemical energy is converted into kinetic energy…or the energy that comes with movement of a mass…and then when I stop all of that kinetic is converted into heat by the disc brakes…and then the cycle starts all over again when I start moving again….I find that kind of interesting…not sure if you will….
