Read Euler, Read Euler, He Is The Master Of Us All

Origin and Context

This celebrated phrase was uttered by Pierre-Simon Laplace in response to his students seeking guidance on learning mathematics. The complete quote, "Read Euler, read Euler, he is the master of us all," reflects both the reverence held for Leonhard Euler and the enduring value of studying original mathematical sources.

Historical Significance

The quote gained prominence in mathematical circles because it encapsulates several important principles:

1. The fundamental nature of Euler's contributions to mathematics
2. The value of reading original sources rather than only modern interpretations
3. The continuity of mathematical knowledge across generations

Euler's Mastery

The phrase's emphasis on Euler's mastery is well-justified by his extraordinary contributions:

• Over 800 published works
• Fundamental discoveries in calculus, number theory, and complex analysis
• Creation of modern mathematical notation including:
  • The symbol 'e' for the natural exponential
  • The symbol 'i' for the imaginary unit
  • The symbol 'π' for pi
  • The function notation f(x)

Educational Philosophy

The quote embodies important principles in mathematical education:

1. Direct Engagement: Reading original works provides insight into mathematical thinking and discovery
2. Historical Perspective: Understanding how mathematical ideas developed historically
3. Mathematical Maturity: Wrestling with original texts builds deeper understanding

Modern Relevance

Today, the phrase continues to influence mathematical education and research:

• Encourages engagement with primary sources in mathematical education
• Promotes the study of classical mathematical works
• Reminds us that even in the age of modern textbooks, original works retain their value

Cultural Impact

The quote has become part of mathematical culture, representing:

• The history of mathematics as a continuous dialogue across centuries
• The importance of mathematical mentorship and guidance
• The value of mathematical pedagogy based on classical works

Related Perspectives

Similar sentiments about returning to original sources have been expressed by other mathematicians:

• André Weil emphasized reading classical authors
• Richard Feynman advocated for understanding foundational principles
• Modern mathematicians continue to find new insights in Euler's original works

Legacy

This quote remains relevant because it reminds us that:

1. Mathematical understanding is built on studying the work of masters
2. Direct engagement with original sources provides unique insights
3. Some mathematical expositions are timeless in their clarity and insight

The phrase continues to inspire mathematicians and students to engage directly with Euler's works, maintaining his influence on modern mathematical thought and education.
