Calculus

History of Calculus

  • Period: to

    Blaise Pascal

    He completed Pascal's Triangle after Chinese mathematician Chia Hsien had come up with the concept. He also invented the first digital calculator.
  • Period: to

    Sir Isaac Newton

    Between 1665 and 1667, Sir Isaac Newton discovered Calculus. Sir Isaac Newton also discovered the Binomical Theorem and Newton's Laws of Motion.
  • Period: to

    Gottfried Wilhelm Leibniz

    Leibniz is known as one of the two founders of Calculus along with Newton. He is known for discovering the "dy/dx" notation, the integral symbol, and even the "=" sign.
  • Period: to

    Euler

    Euler was a mathmetician that is known for creating the symbol for pi (1755) and e (1727). He also worked with the infinite series, created the notation f(x) (1734), and i for the square root of -1 (1777). Euler was the author of multiple books, including "Foundations of Differential Calculus".
  • Period: to

    Pierre-Simon Laplace

    Laplace is known for his work on differential equations, factoring, and many other topics. He founded his theory of probabilities and direct and inverse calculus in 1779. He was referred to as the "Newton of France".
  • Period: to

    Joseph Fourier

    Fourier was responsible for finding the Fourier series. He also expanded the definition of a fuction.
  • Period: to

    Johann Carl Friedrich Gauss

    Gauss made contributions to conics, differential geometry, the number theory, and differential equations. He also won the Copley Medal, which was given to those who made extrodinary discoveries in science.
  • Period: to

    Augustin Louis Cauchy

    Cauchy was known for his contributions to limits, derivatives, and integrals. He made most of his contributions during 1815 to 1830. Cauchy, just like Euler, wrote many books about his discoveries.
  • Period: to

    Johann Peter Gustav Lejeune Dirichlet

    Dirichlet is known for his contributions to the number theory. He published two papers on the number theory in 1838. He also defined the function in a way that is still used today, saying that " is a function of x when each value of x in a given interval has a unique value of y". Dirichlet solved Fermat's Last Theorem with n=5. The proof was published in 1825.
  • Period: to

    Joseph Liouville

    Liouville worked on many aspects of mathematics, including the number theory, complex analysis, and differential geometry. He is also the founder the Liouville Theorem, which states that every bounded entire function must be constant.
  • Period: to

    Bernhard Riemann

    Reimann is known for creating the definition of an integral, which is still used in textbooks today. He also developed the Riemann Hypothesis, which is yet to be solved.
