Im wondering what products/technologies that would not have been poosible without the theories of Quantum electrodynamics, not things that these theories appear to explain.
Quantum electrodynamics is a branch of theoretical physics that combines quantum mechanics and electromagnetism. It describes how particles with electric charge interact with each other through the exchange of photons.
QED allows us to understand the behavior of matter and energy at the smallest scales, which has led to many important discoveries and technologies such as transistors, lasers, and MRI machines.
QED has many practical applications in fields such as electronics, telecommunications, and medicine. It is also used in particle accelerators to study the fundamental building blocks of the universe.
In simple terms, quantum electrodynamics describes how particles with electric charge interact with each other by exchanging tiny packets of energy called photons. These interactions are responsible for all electromagnetic phenomena, from light and electricity to chemical reactions.
QED is closely related to other branches of physics such as quantum mechanics, which describes the behavior of matter at the atomic and subatomic levels, and classical electromagnetism, which explains the behavior of electric and magnetic fields on a larger scale. QED provides a more complete understanding of these phenomena by combining these two theories.
