There is one point that the narrator didn’t look up how to pronounce Fresnel lens (fruh·nel) and it drove me up the wall at first I thought it was just some magical thing I had not heard of before but then they go onto explain exactly what it is and continue to pronounce it wrong. French can be a pain in the butt but I guess I had never seen it written down so I can absolutely see the confusion, still incredibly infuriating. Other than that the book is great highly recommend.
