Scene 2 (9s)
Importance of Mathematics Decision making Economic stability Statistics Practical teachings.
Scene 3 (19s)
Importance of Mathematics. Mathematics is crucial because it builds logical thinking, problem-solving, and analytical skills, essential for daily life (budgeting, cooking, travel) and high-demand careers in tech, finance, science, engineering.
Scene 4 (44s)
History of Mathematics. The history of math started with basic counting in prehistoric times, evolving through ancient civilizations like Babylonians and Egyptians (geometry, early algebra) and Greeks (logic, proofs like Pythagoras). The Islamic Golden Age (Al-Khwarizmi) and India (zero, place-value system) made huge leaps in algebra and number systems. Later, Europeans (Newton, Leibniz) invented calculus, leading to modern math’s explosion in science and tech, building on centuries of global contributions..

SRINIVASA RAMANUJAM. Srinivasa Ramanujam was a great Indian mathematician. He was born on December 22,1887. Ramanujam was a self taught mathematician with exceptional talent. He made significant contributions to mathematics, especially number theory. Ramanujam’s work was recognized by Cambridge professor G.H Hardy. 1729 especially called Ramanujam number..

ARYABHTA Aryabhata (c. 476–550 CE) was a pioneering Indian mathematician and astronomer from the Gupta era, known for his foundational work in algebra, trigonometry, and astronomy, including accurately calculating Pi (π), introducing the concept of zero, explaining Earth’s rotation, and developing sine tables. Contributions: Mathematics: Pi (π): Calculated its value to be approximately 3.1416, accurate to four decimal places. Zero & Place Value: Used zero as a placeholder and developed the decimal system..
Scene 7 (1m 52s)
Leonhard Euler was a highly prolific Swiss mathematician and physicist who is considered one of the greatest mathematicians of the 18th century. He spent most of his life working at the Academies of Sciences in Saint Petersburg, Russia, and Berlin, Germany, publishing hundreds of papers and introducing much of the mathematical notation used today. He introduced and popularized modern notation such as \(f(x)\) for a function, the letter \(e\) for the base of the natural logarithm, \(i\) for the imaginary unit, the Greek letter \(\Sigma \) for summations, and \(\pi \) for the ratio of a circle’s circumference to its diameter.

PYTHAGORAS. Pythagoras of Samos (c. 570 – c. 495 BCE) was a Greek philosopher and mathematician, founder of the Pythagorean school, known for his theorem (\(a^+b^=c^\)) in geometry, and for mystical beliefs that reality is mathematical, influencing Plato and Western thought. He established a secretive brotherhood in Croton, Italy, focused on spiritual purification, communal living, vegetarianism, and mathematical study, though much of his life and teachings are shrouded in mystery due to lack of his own writings..
