Energy
The Steam Engine and the Mechanization of Labor
From pumping water out of English mines to driving locomotives, the steam engine was the work of many hands and gave industry power independent of rivers and muscle.
Communication
The Telegraph and the Beginning of Electrical Communication
Developed by many inventors in the 1830s and 1840s, the electric telegraph made information travel faster than trains and ships and reshaped railways, the press, and markets.
Communication
The Printing Press and Large-Scale Reproduction
Movable type had Asian antecedents; in Mainz, Gutenberg's workshop combined a type mold, alloy, ink and press into a system for producing books.
Computing
The Transistor and the Miniaturization of Circuits
First demonstrated at Bell Labs in December 1947, the transistor replaced vacuum tubes in many roles and made electronics smaller, sturdier and far less power-hungry.
Digital networks
The Creation and Expansion of the Web
The Web began as a proposal to organize documents at CERN in 1989 and grew into a public system of linked pages, distinct from the Internet that carries it.
Automation and computational intelligence
Historical Milestones of Computational Intelligence
Computational intelligence is a research field more than seventy years old, marked by cycles of enthusiasm and reassessment, rival methods and debates that remain open.
Connections
How technologies connect
Every dot is an article. Rows are technology areas and columns are historical periods. Lines join articles that explain each other, so you can see, for instance, how the telegraph leads to networks or how the transistor leads to the personal computer.

Glossary
Full glossary →Terms worth knowing
Short, plain-language definitions linked to the articles that use them.
Packet switching
A method of sending data in small, individually addressed packets that may take different routes through a network and are reassembled at the destination.
Integrated circuit
An electronic circuit whose components and connections are fabricated together on a single piece of semiconductor, commonly called a chip.
Movable type
Individual, reusable pieces carrying a single letter or character, assembled into lines and pages for printing and then taken apart again.
Sociotechnical system
A view of technology as a combination of machines, people, institutions, rules, and practices that depend on one another, rather than as devices alone.
Semiconductor
A material, such as silicon, whose ability to conduct electricity can be controlled, which makes it the basis of transistors and integrated circuits.
Stored-program computer
A computer that keeps its instructions in memory alongside its data, so it can be reprogrammed without rewiring.

Tools and materials
What Technology Is and How Its History Can Be Studied
Technology is more than gadgets: it involves techniques, knowledge, and social organization. See how historians study it and where the evidence runs out.
Tools and materials
The First Tools and the Transformation of Human Life
The oldest known stone tools are more than 2.5 million years old and predate Homo sapiens. See how they were made and what the evidence can and cannot tell us.
Production and industry
Agriculture, Storage, and the Rise of New Techniques
Agriculture arose gradually and independently in many regions. Granaries, sickles, grindstones, and plows brought surpluses and records, but also inequality and disease.
Transport and navigation
The Wheel and the Evolution of Rotating Mechanisms
The vehicle wheel appeared in the fourth millennium BCE, with its origin debated. Axles, spokes, mills, and gears grew from it and prepared the ground for steam and factories.
Communication
Writing as a Technology of Record-Keeping and Administration
Writing arose independently in more than one region, often tied to administration. See its materials, scribes, the alphabet, and the limits of ancient literacy.
Tools and materials
Metallurgy and the Mastery of New Materials
From copper smelting in southeastern Europe to iron furnaces on several continents, metallurgy gave tools, weapons and coins a material that could be melted and reshaped.
Sources and method
Where the information comes from
Articles rely on museums, archives, universities, technical societies, and peer-reviewed literature. We separate invention, prototype, patent, public demonstration, and commercial adoption, and we say when historians disagree.
