I found this video via the Wire Rascals group on Facebook. Besides the interest for those who work in electronics, I think it provides some important insights both on where science has difficulties, and also how science overcomes those difficulties. Note that the presenter explains in a comment on the video that she mispronounces Ohm’s first name, Georg as George and realized it later.
The basic problem for scientific study is that people resist new things, sometimes based on what they assume are well-established facts. Small misunderstandings in one area can lead to greater misunderstandings in another. Scientists are people.
At the same time, the continuing processes of science are more likely to change views, simply because scientists are also looking for something new to establish themselves. Quite often, the resistance to the new ideas and the effort required to overcome that resistance result in refining and improving the basic idea.
Watch the video carefully to see how missing data can lead an experiment astray. Years later, Ohm’s Law is a basic element in thinking about electrical circuits. It’s hard to imagine that it was ever questioned. Unless, of course, we look at unknown data.
