We exist in a sea of electromagnetic force, and are for the most part utterly subject to its dictates. One other force makes itself blatantly known in the course of our mundane activities, namely gravitation, but electromagnetism packs far more power in its punch. It takes a mass the magnitude of Earth to make us weigh ten Newtons to the kilogram, but with a simple rearrangement in the structure of a vanishingly, ridiculously tiny portion of Earth’s mass, we can override the gravitational force of this entire planet, and stand on two feet (by burning sugar in our cells) … or fly to the other side of it in a 747 (by burning avgas in a jet engine).Welcome for the third time!

The images of the early nuclear age have a certain amount of baggage which we need to move beyond to make informed choices for the future. This blog is my humble attempt to encourage people to make that move.
Correction: Welcome for the fourth time! My bad Dan. :)
