During the initial DDX Foreman is standing next to the bookshelf as they discuss the ecstasy and dehydration. As the camera cuts to and from Foreman there is a dark blue book stacked neatly next to his shoulder on the top shelf. As the shot gets tighter on Foreman the book disappears only to reappear in the last shot of the team.
When Dr. Taub examines a patient's eyes with a direct ophthalmoscope, he correctly examines the patient's right eye with his own right eye, holding the ophthalmoscope in his right hand. But when he moves to examine her left eye, he continues to hold the ophthalmoscope in his right hand, and uses his right eye to examine the patient's left eye. In this position, it is impossible to get close enough to actually see the patient's retina, unless he gets so close that he would actually be kissing the patient, a practice frowned upon by most medical establishments. To examine the patient's left eye, he should have moved the ophthalmoscope to his own left eye, held it in his left hand, and he should have moved around to the patient's left side, to examine her left eye to left eye.
