The dolphin experiment was successful to the point that the woman had sex with the dolphin (not intercourse). When the experiment ran out of money it ended. The dolphin missed the woman so much it died of a broken heart. She kept journals (since it was science) and delineated her actions with the young male dolphin. She was trying to teach him to speak words.
The difficulty in teaching a student is directly proportional to the density of the student. - Aesoc’s Law of Information Dissemination.
