    Study Notes

    Srinivasa Ramanujan

    • Born on December 22, 1887, in Erode, India into a modest family.
    • Displayed extraordinary mathematical aptitude from a young age with limited formal education.
    • Self-taught; studied under local mathematicians and developed his own theories.
    • Gained recognition at age 25 by sending work to G.H. Hardy at Cambridge University, leading to a pivotal partnership.
    • Made groundbreaking contributions in number theory, continued fractions, and infinite series.
    • Developed properties of prime numbers, modular forms, and partition functions, introducing novel ideas.
    • Created the Ramanujan-Hardy number known for its intriguing properties.
    • Revolutionized the understanding of π with the Ramanujan series for infinite series.
    • Innovative approaches led to the emergence of new mathematical research branches.
    • His work is visually represented with interactive graphics showcasing its complexity and beauty.

    Al-Khwarizmi

    • Born around 780 CE in Khwarezm (now Uzbekistan) and moved to Baghdad during his youth.
    • Joined the House of Wisdom in Baghdad, a center for scholars to study and translate texts.
    • His exposure to Greek, Persian, and Indian ideas significantly influenced his mathematical contributions.
    • "Al-Kitab al-Mukhtasar fi Hisab al-Jabr wal-Muqabala" formalized algebra, establishing systematic methods for solving equations.
    • His work led to the emergence of the term "algorithm," highlighting his influence on arithmetic with Hindu-Arabic numerals.
    • Made significant advances in trigonometry by compiling tables for sine and cosine functions, aiding astronomy and navigation.
    • Developed crucial techniques for solving equations and performing calculations, influencing the refinement of mathematical methods.

    Leonhard Euler

    • Born on April 15, 1707, in Basel, Switzerland; son of a pastor.
    • Demonstrated early talent in mathematics, encouraged by his father to pursue education at the University of Basel.
    • By age 16, had already made notable progress in mathematics.
    • Moved to St. Petersburg, Russia, to work at the Academy of Sciences, becoming a leading figure in mathematics.
    • Introduced vital notations, including "e" for natural logarithms and "i" for imaginary numbers.
    • Made groundbreaking contributions across calculus, graph theory, and number theory.
    • Euler's formula, ( e^{ix} = \cos(x) + i\sin(x) ), links exponential functions with trigonometric functions.
    • Created Euler's identity, celebrated for its mathematical elegance, often cited for its beauty.
    • His discoveries and notational systems have become essential tools in various branches of mathematics.
