Timeline of calculus
A brief history of calculus
By Donald Lancon Jr
From: http://www.obkb.com/dcljr/mathemat.html
Ancient notions
c.360 B.C.
Eudoxus of Cnidus provides a ``method of exhaustion'', close to the limiting
concept of calculus, which is used by himself and later Greeks to find areas
and
volumes of curvilinear figures; it was based on the lemma that any non-zero
quantity can be made as large as one wishes by multiplying it by a large
enough
constant. <HM>
Pre-calculus
1615
Johannes Kepler uses infinitesimals to calculate volumes of revolution in
New Measurement of the Volume of Wine Casks. <TT>
1635
Bonaventura Cavalieri calculates volumes using infinitely small sections. <TT>
1655
John Wallis studies infinite series in Arithmetic of
Infinitesimals <TT>
1658
Blaise Pascal, working on the sine function, ``almost'' discovers calculus. <TT>
Early calculus
1665
Isaac Newton retires to the country to escape the Great Plague in London;
there he invents the first form of calculus. <TT>
1668
James Gregory includes a geometrical version of the fundamental theorem of
calculus in Geometrical Exercises and the Universal Part of
Geometry. <TT>
1669
Newton includes his method for finding areas under curves in his On
the Analysis of Equations Unlimited in the Number of Their Terms,
circulated privately. <TT>
1670
Isaac Barrow uses methods similar to calculus to draw tangents to curves,
find the lengths of curves, and the areas bounded by curves. <TT>
1675
Gottfried Leibniz introduces the modern notation for integration and the
notation
dx/dy for differentiation; he also determines the product
rule for differentiation. <TT/MN>
1676
Newton writes two letters to Leibniz, hinting at his work with infinite
series and fluxions (his form of calculus); also this year, Leibniz discovers
how to differentiate any fractional power of x. <TT>
1677
Leibniz finds the quotient rule for differentiation. <TT>
Big-time calculus
1684
Leibniz publishes ``A new method for maxima and minima as well as tangents,
which is impeded neither by fractional nor by irrational quantities, and
a
remarkable type of calculus for this''; although only six pages long, few can
understand it. <TT>
1686
Leibniz publishes his method of integral calculus in an issue of Acta
Eruditorum. <TT>
1691
Michel Rolle states without proof the theorem named after him. <TT>
1693
John Wallis publishes Newton's method of fluxions in volume two of his
Mathematical Works. <TT>
1694
Jean Bernoulli discovers the method known as l'Hospital's Rule; it is known
by that name because Marquis Antoine de l'Hospital bought it from Bernoulli and
introduced it in his influential 1696 textbook Analysis of
Infinitesimals. <TT>
1715
Brook Taylor introduces his famous series in Methodus Incrementorum
Directa et Inversa, in which he develops the calculus of finite
differences. <TT>
Later calculus
1797
Joseph-Louis Lagrange introduces the notations f'x and y'
for the derivatives of f(x) and y, respectively. <MN/TT>
1800
Louis F. A. Arbogast introduces the symbol D for the operation
of differentiation. <MN/DC>
1841
Carl Gustav Jacob Jacobi adopts the modern notation for
partial differentiation; Adrien-Marie Legendre originally introduced it in
1786, but immediately
abandoned it. <MN/TT>
1854
Bernhard Riemann defines the integral in a way that does not require
continuity. <TT>
1872
H. Eduard Heine, a student of Karl Weierstrass, presents the modern
``epsilon-delta'' definition of a limit in his Elements. <TT>
Other interesting stuff
2000 B.C. to 200 B.C.
c.1975 B.C.
Mesopotamian mathematicians discover how to solve quadratic equations. <TT>
c.1850 B.C.
Mesopotamian mathematicians discover the so-called Pythagorean theorem
approximately 12 centuries before the time of Pythagoras. <TT>
876 B.C.
The first known use of a symbol for zero appears in India. <TT>
c.465 B.C.
The Pythagorean Hippasus of Metapontum discovers the dodecahedron, a regular
solid whose 12 faces are regular pentagons. There are only 4 other regular
solids: the tetrahedron (4 equilateral triangles), the cube (6 squares),
the
octahedron (8 equilateral triangles), and the icosahedron (20 equilateral
triangles). <TT/CR/HM>
c.450 B.C.
``Achilles'' paradox of Zeno. <HM>
c.350 B.C.
Menaechmus discovers the conic sections: the parabola, ellipse, and
hyperbola. <HM>
c.300 B.C.
The thirteen books of Euclid's Elements (the most widely read
textbook ever written) contains propositions on plane geometry, the
distributive, commutative, and associative laws of arithmetic, quadratic
equations, prime numbers (including the theorem that the set of primes is
infinite), perfect numbers, greatest common divisors, geometric series,
irrational numbers, and solid geometry, including the five regular solids.
Unlike the modern treatment of these ideas, the Greeks used an entirely
geometrical approach in mathematics, using line segments to represent all
magnitudes (numbers). Although the Elements compiles already-known
Greek mathematics, some of the proofs are probably Euclid's own. <HM>
See my Euclid paperfor more information.
c.250 B.C.
Archimedes of Syracuse and the quadrature of the parabola. <HM>
1500 A.D. to present
1575
The first known proof by mathematical induction is included in Francesco
Maurolico's Arithmeticorum Libri Duo; he proves that the sum of the
first
n odd integers is n^2. <TT>
1635
Rene Descartes discovers that any simple convex polyhedron having V
vertices, E edges, and F faces obeys the rule V -
E + F = 2; since his discovery is not published until 1860,
the theorem is named after Leonhard Euler, who rediscovered it in 1752. <TT>
1679
Gottfried Leibniz introduces binary arithmetic in a letter written to
Joachim Bouvet, showing that any number may be expressed by 0's and 1's only. <TT>
1781
Joseph-Louis Lagrange expresses in a letter to his mentor Jean le Rond
d'Alembert his fear that no further progress can be made in mathematics;
despite
this dire prophesy, many of his own contributions are still to come. <TT>
1843
While strolling along the Royal Canal, Sir William Rowan Hamilton devises
a mathematical system which is not commutative; he develops his idea into
a system
of ``quaternions'', similar to that of three-dimensional vectors. His ideas
help to usher in modern abstract algebra. <TT/HM>
1844
Hermann Gunther-Grassman publishes The Study of Extensions,
which deals with multidimensional vectors; he almost single-handedly creates
modern linear algebra. <TT/HM>
1865
August Ferdinand Mobius unveils his single-sided, single-edged figure,
the Mobius strip. <TT>
1877
Georg Cantor proves that the number of points on a line segment is the
same as the number of points in the interior of a square, publication of
the result
is delayed for a year because mathematicians refuse to believe it. <TT>
1890
Giuseppe Peano discovers a one-dimensional, continuous curve that passes
through all the points in the interior of a square. <TT>
1902
Bertrand Russell discovers his ``great paradox''. <TT>
1908
The final edition of Giuseppe Peano's Mathematical Formulas contains
about 4,200 theorems. <TT>
1976
Haken, Appel, and Koch prove with the use of a computer that only four
colors are required to color in any two-dimensional map in such a way that
no
two adjacent regions share the same color; this was conjectured in 1850 by
Francis Guthrie. <TT>
