MoM Ep14: Gaspard Monge

Author: Brian HIrschfield and Rob Hamilton February 9, 2026 Duration: 6:47

This podcast episode of Men of Mathematics discusses Gaspard Monge, the inventor of descriptive geometry and founder of the École Polytechnique, whose work significantly shaped technical education.

Key Topics:

  • Descriptive Geometry
  • École Polytechnique
  • Optimal Transport Problem
  • French Revolution's Impact on Education
  • Monge's relationship with Napoleon

Summary:

Gaspard Monge, born in 1746 in Burgundy to a knife grinder, displayed exceptional mathematical abilities early in life. His talent led him to a military school where he invented a groundbreaking method for designing fortresses. This method, known as descriptive geometry, was classified as a military secret for 15 years due to its strategic value.

Monge's descriptive geometry provided a systematic way to represent three-dimensional objects in two-dimensional drawings using multiple views to capture spatial information precisely. This innovation revolutionized architecture and engineering, replacing immeasurable perspective drawings with a precise language for 3D design. His work evolved from stereotomy, the ancient art of stone cutting, making it mathematical and applicable to various fields. In 1781, Monge introduced the optimal transport problem, concerning the most efficient way to move dirt between piles and holes, which has become fundamental in modern mathematics, machine learning, economics, and meteorology. He also contributed to the study of curved surfaces, influencing Gauss's later work on differential geometry.

During the French Revolution, Monge was instrumental in establishing the École Polytechnique in 1794 to rapidly train engineers. This institution broke from traditional norms by emphasizing rigorous mathematics, meritocracy, practical applications, and the blackboard teaching method. The École Polytechnique produced influential mathematicians and scientists, including Cauchy, Fourier, Poisson, Carnot, Fresnel, and Coriolis, leading to French dominance in mathematics during the early 19th century.

Monge accompanied Napoleon to Egypt and helped found the Institut d'Égypte, contributing to the Description de l'Égypte, which sparked European interest in ancient Egypt. His loyalty to Napoleon would later have consequences. After Napoleon's defeat at Waterloo, the restored monarchy stripped Monge of his honors and expelled him from the Institut de France. His health deteriorated, and upon his death in 1818, the government forbade students from attending his funeral, though many defied the order. Despite the controversies surrounding his later life, Monge's contributions as a creator and teacher profoundly influenced French mathematics and technical education, leaving a lasting legacy in engineering and mathematics worldwide.


What if the foundational ideas securing Bitcoin weren't just abstract concepts but something you could grasp and verify for yourself? Magic Internet Math, hosted by Brian Hirschfield and Rob Hamilton, is built on the conviction that true ownership in the digital age requires personal understanding. This podcast delves into the specific mathematical principles that make Bitcoin function, moving beyond surface-level explanations to explore the actual reasoning behind the protocol. The goal is to replace reliance on experts with genuine, self-verified knowledge. Hirschfield and Hamilton believe that without comprehending this core math, one's belief in the system remains fragile, always subject to external influence and uncertainty. Their discussions aim to transform complex topics into accessible, conversational explorations, breaking down the barriers that often make technical subjects feel intimidating. By focusing on the logical pathways from first principles, the show provides listeners with the tools to build their own intellectual conviction. It’s for anyone who has ever wondered how Bitcoin actually works under the hood and feels that trusting a white paper or a charismatic figure isn't quite enough. The conversations in this podcast are designed to empower, offering a deeper literacy in the cryptographic and economic ideas that define this new asset class. You'll hear detailed walkthroughs of key algorithms, discussions on probability and game theory as they apply to consensus, and an ongoing analysis of how mathematical certainty creates a new form of digital sovereignty. This isn't about investment advice or price speculation; it's a foundational education. Tune in to shift from being a passive holder to an informed participant, equipped with the knowledge to critically evaluate the system you’re trusting with your value. Magic Internet Math frames mathematics not as a gatekeeper, but as the essential tool for liberation and confidence in a rapidly evolving technological landscape.
