As computers have got faster with more memory and storage, it has become possible to carry out more ambitious computational projects. Which of the following statements is most true?
All work in computational chemistry prior to the year 2000 can safely be ignored, as it has been made obsolete by progress since then.
correct
incorrect
All other things being equal, a calculation that takes one week to perform will be better than a calculation that takes one hour.
correct
incorrect
Longer timescales in simulations, larger models in quantum chemical calculations, or better approximations (e.g. better basis sets) can all make the difference between an unsuccessful model and a successful one.
correct
incorrect
Computational methods will necessarily overtake experiment as a source of new chemical knowledge in the near future.
