Thanks so much for providing this lecture series to us. Just the most intellectually stimulating lecture series, and dated Winter 2010, it doesn't get more current than this. Thanks for the history, alternative ideas, And story telling technique. In my days of college in the 1990 time frame classes like this came with prerequisites and a inference that this is Hard stuff to learn, take notes. The new approach of " this is easy to understand" , " don't take notes that distract from the lecture" and " know where to get the math formulas, and databases of info", inspires me to want to teach. In addition to completing lectures from neuroscience ( Gerald Schneider) and berkleys astronomy classes, a biology series lecture, and lastly the serendipity series lectures, has created a new person, that understands the "beginners mind", and I can't wait to get into geology, and chemistry. The professors new way of teaching ha s me literally addicted to knowledge. Thank you so much !
