Been learning DFT, specifically VASP, for the past few weeks and so far it's very cool.

I've been doing very simple calculations with <15 atoms like geometry optimisation, surface energy calculations, etc.

I'm amazed by how useful DFT has been and continues to be for the scientific research community. Google scholar search of 'Density Functional Theory 2020' returns more than 1000+ results.

What is your opinion on all this /computational chemistry in general?
