SUMMARY

Millikan's Oildrop experiment aimed to demonstrate the quantization of electric charge, utilizing a value of e = 1.6022e-19C. The experiment's success was attributed to Millikan's extensive patience and repeated trials over several years, which allowed him to extract a common multiple from his data. However, ethical concerns arose regarding his exclusion of inconsistent data, raising questions about the integrity of his findings. Detailed sources on Millikan's original methods remain scarce, complicating the understanding of his statistical handling of the data.

How did Millikan do it?

I've just completed Millikan's Oildrop experiment (with mixed results) and we haven't actually found the charge of an electron, but simply just tried to demonstrate the quantisation of charge by assuming a value of
e = 1.6022e-19C.

Question is how on Earth did Millikan from his data extract a common multiple in all those values? I have tried to find detailed sources on his exact methods but I haven't been able to find sources or his original paper. Methinks it was an abstract statistical handling of the data.

I do read however this whole ethical issue with him excluding some data that was inconsistent with e...interesting :rolleyes:

You have done the experiment so you are familiar with the equipment and basic methods. The secret to Millikan's success? Patience and repetitions, lots of repetitions. He did not spend 1 or 2 3hr labs, but literally years running the experiment and collecting data.
