CELL MEMBRANES by Professor Fink 

"A scholar should provide guidance for others in the way that a sheep feeds its young, not in the way a bird does. A sheep feeds its lambs on milk, a fully-digested and processed substance, whereas a bird feeds its chicks on what it has half-chewed and then regurgitated." Said Nursi Thank you for these splendid, wonderful lectures.
