Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the quantum field theory paradigm?Fields are considered fundamental entities, with particles as their excitations
2. What is a field in physics?A field is a quantity that has a value at every point in space and time, like a temperature map or a wind map.
3. How do invisible forces like gravity and electricity work?They are carried by fields that fill space. The field pushes or pulls objects, and its strength gets weaker the farther you are from the source.

Tensor Field: A field assigning a tensor (a mathematical object generalizing scalars and vectors) to each point.
Inverse-Square Law: A law where a quantity's magnitude is inversely proportional to the square of the distance from its source.
Quantum Field: A field whose values are quantum operators, forming the basis of quantum field theory.
