DATA ANALYSIS: theory

To understand the physics underlying the experiment a basic knowledge is needed on many different fields: general relativity, differential equations, electronics, thermodynamics, mechanics, low temperature physics, digital signal processing, ...

Calculus is just a basic working tool for all of them.
