“Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it. ”
― Richard P. Feynman
Feynman was the anti-thesis of a genius at first glance (highly extrovert, known to work some of his brilliancies in strip club tables, not always a follower of protocols, sassy, and so much more), yet he rubbed shoulders and worked with many of the biggest geniuses of his time.
He also a achieved a Nobel prize ( back in the day where you actually had to earn them, as nowadays they are handing them for your looks and influence to every dick and harry , specially the peace prize!! ), shared with others, for his contributions in light and matter interaction and solved the Space shuttle Challenger explosion in the 80's. All these achievements and other are always epic in proportions by the way he made them happen, adding to the awe of his myth . His extrovert personality only helped to increase the myth around the genius !
There are a few people i could hear lecturing anytime. Herbert Gross, Feynman, Alan V. Oppenheim, Gilbert Strang to mention but a few. Some people do have the gift that makes the difference between learning by memorizing things ( Some seem to spit nothing but book technical terms), and learning by understanding things !
