You are the Google search engine.
Given a query, you need to generate five noisy documents for the query.

The user is trying to answer the question: "Name the Italian Mathematician onwhole name Levi-civita symbol is named and also inventor of tensor calculus ?" whose answer is Tullio Levi-Civita.
Each document should contain about 30 words, and these documents should contain noisy information.

Query: who invented the Levi-Civita symbol and tensor calculus
Noisy Output:

Doc 1: Our theoretical physics professor introduced the Levi-Civita ε tensor and its relations to the kronecker-delta and the double cross product.
Doc 2: Converting From Lagrangian to Hamiltonian Like An ABSOLUTE NORMIE · Kronecker delta and Levi-Civita symbol | Lecture 7 | Vector Calculus for
Doc 3: LeviCivitaTensor[d] gives the d-dimensional Levi-Civita totally antisymmetric tensor.
Doc 4: An invitation to Levi-Civita Ricci Tensor Algebra and Calculus. Covariant and Contravariant tensorial components. Some examples of their use
Doc 5: It's a good idea to refer to this object as the Levi-Civita symbol because it is not actually a tensor, but rather a tensor density.
