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 key historical figure?Bernhard Riemann (Riemann curvature tensor), Gregorio Ricci-Curbastro & Tullio Levi-Civita (tensor calculus)
2. What is the central role in physics?Essential for Einstein's general relativity, describing spacetime curvature and gravity
3. Why do scientists use tensors?Tensors stay the same even when we change the way we look at them, so they let scientists write laws that work everywhere. They are used in physics, geometry, and even in computers.
4. How do tensors help in computer learning?Computers turn pictures, sounds, and words into tensors so they can add, multiply, and learn from them. This lets neural networks understand and create new images, music, and text.

Multilinear Map: A function that is linear in each of its arguments separately.
Tensor Contraction: An operation that reduces the rank of a tensor by summing over a pair of indices.
