The Crackpot Index is a number that rates scientific claims or the individuals that make them, in conjunction with a method for computing that number. It was proposed by John C. Baez in 1992, and updated in 1998. While the index was created for its humorous value, the general concepts can be applied in other fields like risk management. [1] [2]
In mathematics and mathematical physics, raising and lowering indices are operations on tensors which change their type. Raising and lowering indices are a form of index manipulation in tensor expressions.
The distinction is irrelevant for an unattenuated wave, but becomes relevant in some cases below. For example, there are two definitions of complex refractive index, one with a positive imaginary part and one with a negative imaginary part, derived from the two different conventions. [2] The two definitions are complex conjugates of each other.

A worksheet, in the word's original meaning, is a sheet of paper on which one performs work. They come in many forms, most commonly associated with children's school work assignments, tax forms, and accounting or other business environments. Software is increasingly taking over the paper-based worksheet.
[1] [2] For instance, if the elements of a set A may be indexed or labeled by means of the elements of a set J, then J is an index set. The indexing consists of a surjective function from J onto A , and the indexed collection is typically called an indexed family , often written as { A j } j ∈ J .
A vector treated as an array of numbers by writing as a row vector or column vector (whichever is used depends on convenience or context): = (), = Index notation allows indication of the elements of the array by simply writing a i, where the index i is known to run from 1 to n, because of n-dimensions. [1]
Paper 1 is a multiple choice paper and consists of forty questions, all have a one-point score value. Paper 2 is the subjective area of Maths. There are 15 questions here in total, the first five questions have a three-point score value, questions 6-10 have a four-point score value, and the last five have a five-point score value.
