    You can also make a video about Robert Mulliken and his contribution to chemistry (the concept of electronegativity) because both names: R. Mulliken and R. Millikan are easily confused - yet they both won the Nobel Prize except one was in physics (1923) and the other in chemistry (1966).
    I remember my confusion when studying the history of chemistry, knowing only about the 'oil drop guy' 🙂

    I and my classmates did this experiment in gymnasium (college?) back in 1978 or so.

      I did this experiment for my second year Physics course at Auckland University, New Zealand.
      It was amazing and a privilege to repeat one of the greatest experiments in Physics.
      I passed the course.

    I did the experiment in a physics lab in college. Very interesting. We spent 9 hours taking data. We measured the speed of the drops for zero electric field. positive and negative. From that you can cancel out the drag of the drop going through the air. We got an excellent result. We also did E/M. great video.

      Thank you! 9 hours is a lot of data I bet.

    I had read that among Fletcher's papers which you mentioned was a letter by Fletcher in which he stated that he, not Millikan suggested the use of oil drops rather than water. This would seem to make Fletcher a major contributor to the work rather than just a technician. The letter also discussed his conversation with Millikan in which Millikan said he, Fletcher, could be the sole author on another paper while Millikan was the sole author of the oil drop experiment.

      I was also thinking it could have been a possibility that the experiment's credit could've/should've gone solely to Fletcher... he should've at least been included for sure.

    Have you considered making the music/ambience slightly louder in your videos? I know it's there but I can't hear it at all :')

      The oil is neutral, apart from one or more electrons acquired from the ionization.

      @@purplerpenguinare we assuming that when oil particle receive charge it become the oil particle itself plus one and only one electron? What make us think so?
      Electron = subatomic particles plus charge. Electron is a composition of two independent entities and not single.
      oil doesn’t need additional electron in order to be charged or carry charge.

    There's really no need to show stupid stock video of two guys in lab coats to accompany the mention of "scientists" in the video. This kind of stuff really detracts from an otherwise very informative video. From now on, please assume we know exactly what a scientist looks like!

      Well of course I don't assume you don't know what a scientist looks like... but thank you for the critique.
