Factual error: In the scene where Hodges describes the camera glass to Grissom, he states that camera lenses are curved on one side and flat on the other for a higher refractive index. The refractive index is a property of the glass and has nothing to do with its shape. Also lenses used in cameras can have any shape to them, with even a moderately good lens in a compact camera being made of several pieces of glass with few flat surfaces. This is not modern technology in camera lenses, they have been made like this for decades. Narrowing it down to a non-compact camera by Nikon, Canon or Leica is also wrong, as all manufacturers use these techniques.

Question: Why would Catherine take the blame for the lab explosion? If anyone was to blame it was Hodges. Since he accidentally turned on the hot plate and even admits that sometimes it gets switched on by others accidentally, if he had bothered to make sure he didn't switch it on before leaving the room, the explosion never would have happened.
