Biography

Claude Shannon was mathematician and electrical engineer associated with United States. He founded information theory and showed how Boolean algebra could describe switching circuits.

The bit became a basic unit for measuring information and communication capacity. Together, these contributions connect algebra and functions and statistics and probability to the working problems, tools, and questions of the period.

Mathematical contribution

What this hero added or preserved

Core mathematical work

He founded information theory and showed how Boolean algebra could describe switching circuits.

Method, teaching, or application

The bit became a basic unit for measuring information and communication capacity.

Why this matters

The larger lesson

Claude Shannon shows that mathematics grows through proof, calculation, observation, design, teaching, or careful records. The lasting lesson is that algebra and functions and statistics and probability can turn a difficult question into a method another person can inspect and reuse.

    Life and working period

    Claude Shannon worked as mathematician and electrical engineer in United States.

  2. Legacy

    Lasting mathematical connection

    The bit became a basic unit for measuring information and communication capacity.

Key idea

An equation balances two descriptions

Claude Shannon’s work shows how symbols can represent an unknown quantity while preserving equality.

Example

In 6x + 9 = 27, subtracting 9 and dividing by 6 gives x = 3.

Try it yourself

Solve the equation

Solve 6x + 9 = 27.

  1. Subtract 9 from both sides.
  2. Divide both sides by 6.
  3. Substitute the result to check.
Show the answer

x = 3.

Math at work

Programmers and data analysts use the same habits

Programmers and data analysts use algebra and functions to plan, compare, test, or communicate decisions. Claude Shannon’s work provides a historical example of that connection.
