While I find a way to explain all these controversial issues on the technical fields of electricity, magnetism, electromagnetism, and other field theories in the simplest way as possible, here you are an interesting piece of information on the events occured during the 43rd Congress of the British Association for the Advancement of Science which was held in 1873, which I read in the video and in which you can take a deep insight on the particular way of speaking in some semantic fields for experts of all times and origins (who then are expecting to arrive to some practical accurate agreement with their own colleagues…).
A tiresome task for people all over the world who then have to understand all that hullabaloo.
This video is a reading on the 43rd Congress of the British Association for the Advancement of Science which was held in 1873, and which gathered toghether an important group of scientists such as Clark Maxwell, whose equations on magnetism are widely used today.
Besides, you will see an image I edited taking some text from en.wikipedia, translating some to Spanish, and writing some observations on the subject. The image will be the same for the whole length of the video. This image has lots of information, but don’t worry, I will extend the explanations and comments I’ve made.
