Met with David and tried to build the a new Linux-based Desktop.
Fixed Ubuntu desktop environment problem. Still prefer unity.
Studied root. Learned how to graph histogram. TH1F is the class to create histogram. Applied this on the higgs boson decay data. Code and graph will be attached later. Thing needs to be mentioned: TH1F need to be a pointer in main function, if a Macro is being used.
Poisson’s equation: ∇·∇V=ρ/ε.
When no charge is presented in a region, Poisson’s equation change to be Laplace equation: ∇·∇V=0.
