Question

Are there any tests of quantum field theory one can do using everyday objects?

Answer 1

One of the reasons I love physics is because many of the theories I can test using everyday objects around me. For example I can predict how long it would take for me to drop the ball of a roof using the a=ga=g approximation and basic kinematics. Electricity and magnetism experiments may in some cases require both a bit more equipment and a bit more care, but there are still many cool things you can do without really expensive equipment.

Are there any test of the principles of quantum field theory that one can do using everyday objects or cheap equipment? Also, it should be something that doesn't require special training to be safe to do.

Answer 2

In physics, a field is a physical quantity, represented by a number or tensor, that ... In the modern framework of the quantum theory of fields, even without referring to a test particle, .
