       | Thank you for contributing this course.
       | 
       | That said, its legibility would be helped by some proofreading.
       | Please accept these suggestions for improvements:
       | 
       | Don't _randomly_ format _words_ in bold, such as the word  "
       | _vaguely_ ".
       | 
       | "greek" -> "Greek"
       | 
       | "russian" -> "Russian"
       | 
       | "an hungarian" -> "a Hungarian"
       | 
       | reference: https://www.berlitz.com/es-mx/blog/gentilicios-en-
       | ingles
       | 
       | Same rule for toponyms:
       | 
       | "greece" -> "Greece"
       | 
       | Greek proper names have different forms in English than in
       | Spanish:
       | 
       | "Euclide" -> "Euclid"
       | 
       | reference: https://en.wikipedia.org/wiki/Euclid
       | 
       | Join sentence fragments:
       | 
       | "packing of particles. It was" -> "packing of particles, it was"
       | 
       | Capitalization, inconsistent spelling:
       | 
       | "euclidean", "Euclidian" -> "Euclidean"
       | 
       | "non-euclidian" -> non-Euclidean
       | 
       | Incorrect word choice:
       | 
       | replace: "This fifth postulate posteriorly defined any attempt to
       | try to prove it from _other_ postulates of geometry. "
       | 
       | with: "This fifth postulate subsequently defied any attempt to
       | try to derive it from the other postulates of geometry."
       | 
       | "19 th" -> "19th"
       | 
       | Unnecessary capitalization:
       | 
       | "Alternative proposed Postulate" - > "Alternative proposed
       | postulate"
       | 
       | Incorrect proposition:
       | 
       | "Academia rejection to the proposal" -> "Academic rejection of
       | the proposal:"
       | 
       | Typographical error:
       | 
       | "universitary" -> "university"
       | 
       | "Different persons came to the same idea from differents
       | backgrounds" -> "Different people arrived at the same idea from
       | different backgrounds."
       | 
       | "Standar" -> "Standard"
       | 
       | Contrast with the Spanish word "estandar".
       | 
       | "erlangen programme" -> "Erlangen program"
       | 
       | "EXISTENTS" -> "existence"
       | 
       | "lipschitz continuous" -> "Lipschitz continuous"
       | 
       | "elemen" -> "element"

       | Btw, It's fascinating how simmetry can be applied in such a
       | practical way.

       | And from there you could compute the symmetries and curvature of

       | energy for the system or some other conserved quantities, and
       | then use that as an anomaly detector (change in the energy of the
       | system means there was some outside interference).
