If you remember yesterday I commented on the different ways of saying the same in mathematics speaking of the gradient and how physicists write it differently from the engineers. Today […]

Mathematical notation is something that, often, complicates the formulas we see, mainly because according to who does that is the one that uses. Come on, that the notation of things […]

Today I want to comment on a very important physical concept from the mathematical point of view, the scalar field. A scalar field $latex \gamma (\overrightarrow{r})$ is just a function […]

Continuing “Saturdays are made for mathematics” and bearing in mind that the other time I talk to you about how false are the centrifugal forces and centripeta being a differential […]
