Daniel Bernoulli: Born on February 8, 1700 in Groningen, Netherlands. Family Background

  • Parents: His parents were Johann Bernoulli and Dorothea Falkner.
  • Mathematical Legacy: Mathematics ran in the family; his father Johann Bernoulli and his uncle Jacob Bernoulli were both accomplished mathematicians. Johann Bernoulli was nicknamed the “Archimedes of his age.”
  • Educational Influence: His mother Dorothea came from a wealthy family in Basel, Switzerland, and his father held the chair of mathematics at the University of Groningen. The family later moved to Basel, where Johann became a chair of mathematics at Basel University.

Education and Beginnings

  • Educational Journey: Daniel studied medicine in Heidelberg, Germany; Strasbourg, France; and Basel, Switzerland. He was taught advanced mathematics and physics by his father and older brother Nicolaus Bernoulli.
  • Passion for Mathematics: Despite his father’s wishes for him to pursue business, Daniel had a strong passion for mathematics.
  • Mathematical Contributions: Daniel’s early mathematical contributions included work on fluid mechanics, probability theory, differential equations, and geometry.

European Exploration and Contributions

  • Venice and Practical Medicine: In 1723, Daniel moved to Venice to study practical medicine while continuing his mathematical pursuits. He observed fluid mechanics and conducted experiments, noticing the relationship between the height of water, pressure, and velocity.
  • Publication and Recognition: He published his first work, “Mathematical Exercises,” in 1724, which covered various scientific topics.
  • Scientific Recognition: Bernoulli’s work in designing a sand-clock for timekeeping at sea won him a prestigious prize. He was offered a professorship at the Academy of Sciences in Saint Petersburg, Russia.

Life in Saint Petersburg

  • Academic Position: Bernoulli initially held a professorship in physiology due to his medical background.
  • Academic Relationships: He engaged in academic disputes with fellow professors initially but later formed a strong collaboration with mathematician Leonhard Euler.
  • Collaboration with Euler: Euler’s arrival in 1727 marked a turning point. They exchanged ideas and made significant contributions to mathematics.

Contributions to Science

  • Hydrodynamica: Bernoulli’s masterpiece on fluid mechanics, “Hydrodynamica,” completed in 1733, explored the relationship between fluid speed and pressure.
  • Kinetic Theory of Gases: Bernoulli’s insight into the distribution of particle speeds laid the foundation for the kinetic theory of gases, later refined by James Clerk Maxwell.

The Bernoulli Effect and Risk Measurement

  • The Bernoulli Effect: Bernoulli’s work on energy conservation in fluids led to the discovery of the Bernoulli Effect, explaining pressure changes in fluid flow. This effect is crucial in understanding lift generation in aircraft wings.
  • Risk Measurement: In 1738, Bernoulli published a paper on risk measurement, using geometric mean and utility theory. His work influenced fields like economics, portfolio theory, and behavioral ecology.

Personal Life and Legacy

  • Return to Basel: Bernoulli’s health deteriorated in Saint Petersburg, prompting his return to Basel in 1733.
  • Academic Achievements: Despite disputes and controversies, Bernoulli left a lasting impact on mathematics, physics, and various interdisciplinary fields.
  • Legacy: He passed away on March 17, 1782, leaving behind a legacy of contributions to mathematics, fluid mechanics, and risk theory.

Plagiarism Controversy

  • Plagiarism by Father: A bitter turn of events saw his father, Johann Bernoulli, plagiarize his work, releasing a book called “Hydraulica,” dated as completed in 1732.
