At my University, we get (in Experimental Physics) weekly homework which consists of three exercises with 3, 3 and 4 points (thus giving a total of 10 points for each sheet). Now I have received the sheet for the next week, on which the third task is "Oil Drop in an electric field". The first half of the task is to determine the number of elementary charges on the oil drop according to the numbers given in the task. The second part asks: After reading that, I was concerned. I was concerned that students would get two points by writing "Robert A. Millikan" on the sheet. In the last semester, in Experimental Physics 1, there never had been a question like that. Everything was for calculation and the only questions which required to evaluate something were based on the calculation results of the other partial tasks. Did you experienced something like this? What did you think about this? In my opinion, the tasks are to train the usage of the laws and principles given in the lecture.
