I drop sometimes by Physics Forums to pose and answer questions… and I realized that you can have a blog there too. So I opened one and put an entry, you can see it here. In a single day it got around 3 x visitors than here… So I’ll keep both for a while, basically with the same contents… :)
An important organization issue of this blog is that each post will have a tag stating its expected audience. The human population is divided, to this effect, into five categories:
Muggles: people with no interest whatsoever in physics, no curiosity about the world around them. Also called philistines. I don’t think we will devote many posts to them…
Little Grasshopper: lowly initiate in the mysteries of the universe, seekers of beauty and truth, striving for illumination. Freshman level. Also called little padawans or hobbits.
Rangers of the North: they’ve been allowed to reach some glimpses of illumination, like the understanding of 
Jedi Master: they’ve followed their path through the mindscape, unveiling mysteries, and also trying to show it to others. Also named istari, wizards, gurus…
Sensei of the Galaxy: (銀河 の 先生) those touched by the fingers of the gods… I don’t think we’ll devote many posts to them, either.
Hello, and welcome everybody to the physics napkins blog! It will contain random coffee chat on physics, maths and other cool stuff. Or, in other terms, about the universe and the funny things it contains… (or does not contain, if anything)
Without further ado, let’s start!
