The teory of DFT and HF

Todays computational chemisty will not far from those above two words. DFT or density functional theory and HF or Hatree Fook. The last term is sometimes called as ab initio model. What is DFT or HF? and what is the different between them? That question is rather complicated to be answer as it takes long detail explanation, complicated, and required good understanding in basic physical chemistry science. Anyway, I hope this simple explanation will tell you correctly about those two ‘magical’ words.

It is better to start from HF or Hartree Fook teory which is classified as ab initio model of quantum chemistry. And also better to review our knowledge about atom and electron.
