Thanks to MIT for explaining that one. I can think of an explanation for the origin of that phrase. You see, the Summer gets "tricked" into thinking it's gonna last. But alas! The Winter inevitably comes and the few days of its warm reign are over. And just like this short-lived summer period, the Indians got tricked by their conquerors too. Thus the term, "Indian Summer".And Thank You MIT for these wonderful videos. Keep up the great work!!Great Profs teaching in a great way!####[['MIT', 'Other', 'POS'], ['Profs', 'Instructor', 'POS'], ['videos', 'Course_General_Feedback', 'POS']]
