This document is a physics project final report that introduces the concept of combining higher order vectors and the connection on a manifold. It defines higher order vectors up to arbitrary order using both index and coordinate-free representations. It then investigates how higher order vectors and the connection transform between coordinate systems. Finally, it suggests two ways of combining second and third order vectors with the connection and shows how this naturally introduces the torsion and curvature of the manifold. The report emphasizes developing coordinate-free definitions and discusses potential applications, such as rewriting equations from general relativity by viewing higher order vectors as a new source of matter.

File is a container for storing information. It can be treated as a sequence of characters. Unlike the old DOS files, a UNIX file doesn‟t contain eof (end- of –file) mark. A file‟s size is not stored in the file, nor even its name. All files attributes are kept in separate area of hard disk, not accessible to humans, but only to the kernel.ThesisScientist.com

Linux is an open source operating system kernel created by Linus Torvalds. It manages computer hardware resources and acts as an interface between users and hardware. There are many Linux distributions like Red Hat, Debian, Ubuntu, CentOS etc. that package the Linux kernel along with other software. Basic Linux commands allow users to manage files, directories and perform other tasks through the terminal. These include commands to view system information, navigate directories, manage files and perform other administrative tasks.
