The last of my three posts tonight is a mysterious dual system of units developed my rival blog (in Spanish language mainly): http://tardigrados.wordpress.com/ His author launched an interesting but speculative dual system of units in which every physical quantity seems … Continue reading

The second paper I am going to discuss today is this one: http://inspirehep.net/record/844954?ln=en In Note on the natural system of units, Sudarshan, Boya and Rivera introduce a new kind of “fundamental system of units”, that we could call G2 system … Continue reading

Brazil is experimenting an increase of scientific production. Today, I am going to explain this brazilian paper http://arxiv.org/abs/0711.4276v2 concerning the number of fundamental constants. The Okun cube of fundamental constant, firstly introduced by Gamov, Ivanenko and Landau, has raised some … Continue reading

Following the thread I began in the previous blog post, today we are going to learn about a non common but very general and universal system of natural units. They were officiallly introduced without name in the literature, until a … Continue reading
