One of the most impressive movie in the world of the first-principles theoretical calculation. The molecule is initially 3 Angstroms above the surface. But this calculation by Lindan et al. does not include any adjustable parameters. Seeing is a believing. I like these jokes.
Somebody says that published paper is a kind of currency in the academic world.
Actually people write two papers per minintue in the natural science world, but they just read less than 1 percent of the papers published. They just want to publish a paper without nasty peer review. Assumption is the mother of all screw-ups. Biologists think they're biochemists. Biochemists think they're chemists.
