EM is but a tiny Newtonian Segment of the inordinately infinite spread of energy and its vibrations...?
When x-rays are needed, a simple torch-light would not do? When a brilliant electronic flash-light (or strobe) is what shall capture the picture, a laser might not be ideal, as tools go? Without Engineers and Doctors arriving at a node where their paths crossed and bio-medical engineering became a reality, robotic-surgery did not come about and making headline news in advanced or specialized forums of conversation?
Glad to have run into your sharings, and yes vibrations and energy-levels do matter? After all, a band-aid or poultice might often help, but after a serious major surgery (or before?) more rigorous procedures and rituals might become essential...?
Or, when planning something as potentially-dangerous as a space-launch, whether to explore moon, or mars or simply to deliver sustenance to our brothers and sisters who are zipping around the globe at blinding speeds and rely on those from Mother Earth to make absolutely sure that the earth to satellite communication continues? Impossible without aerospace engineers, of course...!
