    If every single teacher did a "Why this matters" for each chapter I would have been studying this subject a lot sooner.

    I'm absolutely loving the way this guy teaches. It isn't for nothing that MIT is said to be the best university in the world ...

    This is the difference between a good and bad teacher. A good teacher can make you love complicated or even boring scientific courses and a bad teacher can make your hate grow like a polymerization reaction.

      Lol, one of my most boring chem professors was a polymer chemist. We used to say he's made so many plastics that his sense of humor has become plastic too...

    Professor FYI the solution to this problem is life cycle which is connected to sustainability second new molecular techniques have been advanced for condensation and ring opening polymers that extends life times for over 100 years with no degradation while polyolefins can now be extended by 400 percent solely by controlling the morphology and orientation of crystals during fabrication thereby elimination oxygen diffusion and migration and extraction of the fortification changing the kinetic rate of free radical in situation degradation so please update your facts

    A professor having so much difficulties in writing a (wrong by the way) phenyl group structure, cannot be a chemist.
