Penetrations

The development of the field of electromagnetism is a good example of how scientists extend each others’ work, even working in different countries.

The strong interaction, the weak interaction, gravitation, and electromagnetism are the four fundamental interactions in nature. So many modern devices depend on electromagnetism (such as the telephone, radio, computers, wireless communications), but, even more profoundly, without electromagnetism there would be no light nor heat; atoms and molecules would not hold together and would not interact chemically with each other.
