Literature | R in prescriptions. The ornamental part of this letter is the symbol of Jupiter , under whose special protection all medicines were placed. The letter itself (Recipe, take) and its flourish may be thus paraphrased: "Under the good auspices of Jove, the patron of medicines, take the following drugs in the proportions set down." It has been suggested that the symbol is for Responsum Raphaelis, from the assertion of Dr. Napier and other physicians of the seventeenth century, that the angel Raphael imparted them. R is called the dog-letter, because a dog in snarling utters the letter r-r-r-r, r-r, r-r-r-r-r, etc.- sometimes preceded by a g. "Irritata canis quod RR quam plurima dicat." Lucillus. "[R] that's the dog's name. R is for the dog." - Shakespeare: Romeo and Juliet, ii. 4. The three R's.

The misconception
Contrary to what most mathematicians believe, Georg Cantor's first proof that the set of all real numbers is uncountable was not his famous diagonal argument, and did not mention decimal expansions or any other numeral system. The theorem and proof below were found by Cantor in December 1873, and published in 1874 in Crelle's Journal, more formally known as Journal für die Reine und Angewandte Mathematik (German for Journal for Pure and Applied Mathematics). Cantor discovered the diagonal argument in 1877.
The theorem
Suppose a set R is
Then R is not countable.
- linearly ordered, and
- densely ordered, i.e., between any two members there is another, and
- has no "endpoints", i.e., smallest or largest members, and
- has no gaps, i.e., if it is partitioned into two sets A and B in such a way that every member of A is less than every member of B, then there is a boundary point c, so that every point less than c is in A and every point greater than c is in B.
The proof
The proof begins by assuming some sequence x1, x2, x3, ... has all of R as its range. Define two other sequences as follows:
The two monotone sequences a and b move toward each other. By the "gaplessness" of R, some point c must lie between them. The claim is that c cannot be in the range of the sequence x, and that is the contradiction. If c were in the range, then we would have c = xi for some index i. But then, when that index was reached in the process of defining a and b, then c would have been added as the next member of one or the other of those two sequences, contrary to the assumption that it lies between their ranges.
- a1 = x1.
- b1 = xi, where i is the smallest index such that xi is not equal to a1.
- an+1 = xi, where i is the smallest index greater than the one considered in the previous step such that xi is between an and bn.
- bn+1 = xi, where i is the smallest index greater than the one considered in the previous step such that xi is between an+1 and bn.
Real algebraic numbers and real transcendental numbers
In the same paper, published in 1874, Cantor showed that the set of all real algebraic numbers is countable, and inferred the existence of transcendental numbers as a corollary. That corollary had earlier been proved by quite different methods by Joseph Liouville.

Missing Persons
The number of missing people grew to estimates as high as over 6000 in the months following the attack, but steadily declined as stories were checked and duplicate entries removed. (See Timeline of WTC missing).
As of August 2002, there were approximately 90 people who were officially missing; that is, their remains had not been identified and no family members had requested a death certificate.
Detailed listing.
Survivors
The great majority of the over 40,000 people working at the World Trade Center at the time of the attack evacuated safely, including 18 who escaped from above the impact zone in the second tower hit. By 9/20/2001 6291 people, including rescue and recovery workers, had been treated for injuries.
Detailed listing.
Pentagon
The Pentagon reports 125 staffers killed or missing, with 121 remains recovered and identified, as of Sept. 11, 2002. At least one person died later as a result of wounds incurred.
The listing and memorial.
Missing Persons
The Pentagon reports 4 staffers missing. One passenger on the airliner which hit the Pentagon was also never identified.
Detailed listing.
Survivors
88 treated at hospital.
Detailed entry.
Victim legends
Due to the very large number of World Trade Center casualties and missing persons, victim legends were a common form of September 11, Terrorist Attack urban legends. These were tales of victims who did not exist, spread by word-of-mouth and the Internet. Official sites, such as http://www.september11victims.com, contain accurate entries and are trusted content. Because Wikipedia, and many other websites allowed freely adding victims, there were no doubt many obvious fake entries. Fake victims added to these lists were often simply missing at the time of the attacks, or actually survivors of the attacks.

coordinates in mathematics
A point P in the Euclidean space Rn is given by an n-tuple P=(r1,...,rn) of real numbers r1,...,rn.These numbers r1,...,rn are called the coordinates of the point P.
If a subset S of an Euclidean space is mapped continuously onto another topological space, this defines coordinates in the image of S.

In category theory, see covariant functor.
In tensor analysis, a covariant coordinate system is reciprocal to a corresponding contravariant coordinate system.
Roughly speaking, a covariant tensor is a vector field that defines the topology of a space; it is the base which one measures against.
A contravariant vector is thus a measurement or a displacement on this space.
Thus, their relationship can be represented simply as:
Another way of defining covariant vectors is to say that "covariant vectors" are actually one-forms, that is to say, real-valued linear functions on "contravariant" vectors. These one-forms can then be said to form a dual space to the vector space they take their arguments from.
If e1, e2, e3 are contravariant basis vectors of R3 (not necessarily orthogonal nor of unit norm) then the covariant basis vectors of their reciprocal system are:
Then the contravariant coordinates of any vector v can be obtained by the dot product of v with the contravariant basis vectors:
Likewise, the covariant components of v can be obtained from the dot product of v with covariant basis vectors, viz.
Then v can be expressed in two (reciprocal) ways, viz.
The indices of covariant coordinates, vectors, and tensors are subscripts. If the contravariant basis vectors are orthonormal then they are equivalent to the covariant basis vectors, so there is no need to distinguish between the covariant and contravariant coordinates, and all indices are subscripts.

First Theorems about Groups
A group (G,*) is usually defined as:
G is a set and * is an associative binary operation on G, obeying the following rules (or axioms):
Axioms A1 and A2 follow from the definition of "associative binary operation", and are sometimes omitted, particularly A1.
- A1. (G,*) has closure. That is, if a and b are in G, then a*b is in G
- A2. The operation * is associative, that is, if a, b, and c are in G, then (a*b)*c=a*(b*c).
- A3. G contains an identity element, often denoted e, such that for all a in G, e*a=a*e=a.
- A4. Every element in (G,*) has an inverse; if a is in G, then there exists an element b in G such that a*b=b*a=e.
Where no danger of confusion is possible, the group (G,*) will simply be referred to as "the group G"; but it is important to remember that the operation "*" is fundamental to the description of the group. For example, in the real numbers, we can speak of both the group (R,+), which is the additive group of reals with identity 0; and the group (R#, *), which is the multiplicative group of the reals (excluding 0), which has identity 1.
We can state simpler versions of A3 and A4:
In the sequel, we will assume the axioms A1, A2, A3' and A4'. We first show in Theorem 1.1 and 1.2 that these assumptions actually imply A3 and A4. We will then go on to prove several other theorems, the most important of which are that every group has a unique identity, and every element in a group has a unique inverse.
- A3'. G contains an identity element, often denoted e, such that for all a in G, a*e=a.
- A4'. Every element in (G,*) has an inverse; for all a in G, there exists an element in G, denoted a -1, such that a*a -1 = e.
Theorem 1.1: For all a in G, a -1*a = e.
Thus every right inverse in a group is necessarily a left inverse.
- By expanding a -1*a, we get
- a -1*a = a -1*a*e (by A3)
- a -1*a*e = a -1*a*(a -1*(a -1) -1) (by A4, a -1 has an inverse denoted (a -1) -1)
- a -1*a*(a -1*(a -1) -1) = a -1*(a*a -1)*(a -1) -1 = a -1*e*(a -1) -1 (by associativity and A4)
- a -1*e*(a -1) -1 = a -1*(a -1) -1 = e (by A3 and A4)
- Therefore, a -1*a = e
Theorem 1.2: For all a in G, e*a = a.
Thus, the identity in a group is both a left and right identity. (We will justify the use of the term "the identity" momentarily).
- Expanding e*a,
- e*a = (a*a -1)*a (by A4)
- (a*a -1)*a = a*(a -1*a) = a*e (by associativity and the previous theorem)
- a*e = a (by A3)
- Therefore e*a = a
The following theorem demonstrates a fundamental property enjoyed by groups, which other more general structures (such as semigroups) lack:
Theorem 1.3: For all a,b in G, there exists a unique x in G such that a*x = b.
Theorem 1.4: The identity element of a group (G,*) is unique.
- Certainly, at least one such x exists, for if we let x = a -1*b, then x is in G (by A1, closure); and then
- a*x = a*(a -1*b) (substituting for x)
- a*(a -1*b) = (a*a -1)*b (associativity A2).
- (a*a -1)*b= e*b = b. (identity A3).
- Thus an x always exists satisfying a*x = b.
- To show that this is unique, if a*x=b, then
- x = e*x
- e*x = (a -1*a)*x
- (a -1*a)*x = a -1*(a*x)
- a -1*(a*x) = a -1*b
- Thus, x = a -1*b
As a result, we can speak of the identity element of (G,*) rather than an identity element. Where different groups are being discussed and compared, often eG will be used to identify the identity in (G,*). By analogy to the group of reals, the identity is also sometimes denoted as 1 (or 1G ) in groups that are written multiplicatively, and as 0 (or 0G ) in groups that are written additively.
- a*e = a (by A3)
- Apply theorem 1.3, with b = a.
Theorem 1.4: The inverse of each element in (G,*) is unique; equivalently, for all a in G, a*x = e if and only if x=a -1.
As a result, we can speak of the inverse of an element x, rather than an inverse. When the group operation is written multiplicatively (as it is here), we denote the inverse of x as x -1. When the group is written additively (i.e., in (G,+)), the inverse of x is written as -x.
- If x=a -1, then a*x = e by A4.
- Apply theorem 1.3, with b = e.
Theorem 1.5: For all a belonging to a group (G,*), (a -1) -1=a.
Theorem 1.6: For all a,b belonging to a group (G,*), (a*b) -1=b -1*a -1.
- a -1*a = e.
- Therefore the conclusion follows from theorem 1.4.
The results of the following theorem are often called the cancellation rules for a group:
- (a*b)*(b -1*a -1) = a*(b*b -1)*a -1 = a*e*a -1 = a*a -1 = e
- Therefore the conclusion follows from theorem 1.4.
Theorem 1.7: For all a,x,y, belonging to a group (G,*), if a*x=a*y, then x=y; and if x*a=y*a, then x=y.
- If a*x = a*y then:
- a -1*(a*x) = a -1*(a*y)
- (a -1*a)*x = (a -1*a)*y
- e*x = e*y
- x = y
- If x*a = y*a then
- (x*a)*a -1 = (y*a)*a -1
- x*(a*a -1) = y*(a*a -1)
- x*e = y*e
- x = y
Given a group (G, *), if the total number of elements in G is finite, then the group is called a finite group. The order of a group (G,*) is the number of elements in G (for a finite group), or the cardinality of the group if G is not finite. The order of a group G is written as |G| or (less frequently) o(G).
A subset H of G is called a subgroup of a group (G,*) if H satisfies the axioms of a group, using the same operator "*", and restricted to the subset H. Thus if H is a subgroup of (G,*), then (H,*) is also a group, and obeys the above theorems, restricted to H. The order of subgroup H is the number of elements in H.
A proper subgroup of a group G is a subgroup which is not identical to G. A non-trivial subgroup of G is (usually) any subgroup of G which contains an element other than e.
Theorem 2.1: If H is a subgroup of (G,*), then the identity eH in H is identical to the identity e in (G,*).
Theorem 2.2: If H is a subgroup of G, and h is an element of H, then the inverse of h in H is identical to the inverse of h in G.
- If h is in H, then h*eH = h; since h must also be in G, h*e = h; so by theorem 1.3, eH = e.
Given a subset S of G, we often want to determine whether or not S is also a subgroup of G. One handy theorem that covers the case for both both finite and infinite groups is:
- Let h and k be elements of H, such that h*k = e; since h must also be in G, h*h -1 = e; so by theorem 1.3, k = h -1.
Theorem 2.3: If S is a non-empty subset of G, then S is a subgroup of G if and only if for all a,b in S, a*b -1 is in S.
The intersection of two or more subgroups is again a subgroup.
- If for all a, b in S, a*b -1 is in S, then
- e is in S, since a*a -1 = e is in S.
- for all a in S, e*a -1 = a -1 is in S
- for all a, b in S, a*b = a*(b -1) -1 is in S
- Thus, the axioms of closure, identity, and inverses are satisfied, and associativity is inherited; so S is subgroup.
- Conversely, if S is a subgroup of G, then it obeys the axioms of a group.
- As noted above, the identity in S is identical to the identity e in G.
- By A4, for all b in S, b -1 is in S
- By A1, a*b -1 is in S.
Theorem 2.4: The intersection of any non-empty set of subgroups of a group G is a subgroup.
In a group (G,*), define x0 = e. We write x*x as x² ; and in general, x*x*x*...*x (n times) as xn. Similarly, we write x -n for (x -1)n.
- Let {Hi} be a set of subgroups of G, and let K = ∩{Hi}.
- e is a member of every Hi by theorem 2.1; so K is not empty.
- If h and k are elements of K, then for all i,
- h and k are in Hi.
- By the previous theorem, h*k -1 is in Hi
- Therefore, h*k -1 is in ∩{Hi}.
- Therefore for all h, k in K, h*k -1 is in K.
- Then by the previous theorem, K=∩{Hi} is a subgroup of G; and in fact K is a subgroup of each Hi.
Theorem: Let a be an element of a group (G,*). Then the set {an: n is an integer} is a subgroup of G.
A subgroup of this type is called a cyclic subgroup; the subgroup of the powers of a is often written as <a>, and we say that a generates <a>.
If there is a positive integer n such that an=e, then we say the element a has order n in G. Sometimes this is written as "o(a)=n.
If S and T are subsets of G, and a is an element of G, we write "a*S" to refer to the subset of G made up of all elements of the form a*s, where s is an element of S; similarly, we write "S*a" to indicate the set of elements of the form s*a. We write S*T for the subset of G made up of elements of the form s*t, where s is an element of S and t is an element of T.
If H is a subgroup of G, then a left coset of H is a set of the form a*H, for some a in G. A right coset is a subset of the form H*a.
Some useful theorems about cosets, stated without proof:
Theorem: If H is a subgroup of G, and x and y are elements of G, then either x*H = y*H, or x*H and y*H have empty intersection.
Theorem: If H is a subgroup of G, every left (right) coset of H in G contains the same number of elements.
\'Theorem': If H is a subgroup of G, then G is the disjoint union of the left (right) cosets of H.
Theorem: If H is a subgroup of G, then the number of distinct left cosets of H is the same as the number of distinct right cosets of H.
Define the index of a subgroup H of a group G (written "[G:H]" ) to be the number of distinct left cosets of H in G.
From these theorems, we can deduce the important Lagrange's Theorem relating the order of a subgroup to the order of a group:
Lagrange's Theorem: If H is a subgroup of G, then |G| = |H|*[G:H].
For finite groups, this also allows us to state:
Lagrange's Theorem: If H is a subgroup of a finite group G, then the order of H divides the order of G.
