I have never seen a proton or electron spinning around it. I have never actually seen a chromosome. I trust that they exist because people who I trust tell me they do.
Daniel LevitinI don't think I'm always right, but I would like to empower people to come to sound conclusions using a systematic way of looking at things.
Daniel LevitinFor the artist, the goal of the painting or musical composition is not to convey literal truth, but an aspect of a universal truth that if successful, will continue to move and to touch people even as contexts, societies and cultures change. For the scientist, the goal of a theory is to convey "truth for now"--to replace an old truth, while accepting that someday this theory, too, will be replaced by a new "truth," because that is the way science advances.
Daniel LevitinThe emerging picture from such studies is that ten thousand hours of practice is required to achieve the level of mastery associated with being a world-class expert - in anything. In study after study, of composers, basketball players, fiction writers, ice skaters, concert pianists, chess players, master criminals, and what have you, this number comes up again and againโฆno one has yet found a case in which true world-class expertise was accomplished in less time. It seems that it takes the brain this long to assimilate all that it needs to know to achieve true mastery.
Daniel LevitinIn order to be a world-class expert in anything, be it audiology, drama, music, art, gymnastics, whatever, one needs to have a minimum of 10,000 hours of practice. Unfortunately, it doesn't mean that if you put in 10,000 hours that you will become an expert, but there aren't any cases where someone has achieved world-class mastery without it! So the time spent at the activity is indeed the most important and influential factor.
