Sarvarthapedia is a comprehensive collection of universal knowledge
A Unified Encyclopedia of Human Technological Civilization, Infrastructure, Intelligence, and Applied Science
The history of human civilization is inseparable from the history of technology, applied science, and the organized systems through which societies transformed matter, energy, information, and intelligence into durable forms of power. From the earliest chipped Oldowan stone tools discovered at Gona, Ethiopia and dated to nearly 2.6 million years before present, to the emergence of artificial intelligence systems, quantum computing, and planetary-scale digital infrastructure in the early 21st century, technological development has formed the material framework of human existence. Every major transformation in population, agriculture, warfare, commerce, medicine, communication, and governance has depended upon advances in tools, processes, measurement, and engineering.
The first great technological transition occurred during the Neolithic Revolution between approximately 10,000 and 7000 BCE in regions including Mesopotamia, the Levant, the Old-Vedics (Before 4500 BCE) and the Neo-Vedics (4500 BCE – 600 BCE), and the Yellow River basin, where communities developed agriculture, animal domestication, irrigation canals, pottery kilns, woven textiles, and permanent settlements. By 3500 BCE, urban societies in Sumer and Egypt had introduced bronze metallurgy, wheeled transport, monumental construction, and formal writing systems such as cuneiform and hieroglyphics, enabling administration, taxation, engineering records, and long-distance trade.
Classical civilizations expanded the technological foundations of infrastructure and scientific inquiry. The Greeks advanced geometry, mechanics, and optics; the Romans constructed roads, aqueducts, arches, and hydraulic concrete across Europe and the Mediterranean; while Han dynasty China pioneered papermaking, the blast furnace, the magnetic compass, and sophisticated astronomical instruments. Between the 8th and 13th centuries, the Islamic Golden Age, centered in cities such as Baghdad, Cairo, and Cordoba, preserved and extended mathematics, medicine, chemistry, and mechanical engineering through scholars including Al-Khwarizmi, Ibn al-Haytham, and Al-Jazari, whose works influenced later European science.
The invention of the printing press by Johannes Gutenberg at Mainz around 1450 accelerated the transmission of technical knowledge throughout Europe. The subsequent Scientific Revolution of the 16th and 17th centuries introduced systematic experimentation through figures such as Galileo Galilei, Isaac Newton, Robert Hooke, and Christiaan Huygens, establishing the foundations of modern physics, astronomy, mechanics, and precision instrumentation. By the late 18th century, the Industrial Revolution, originating in Britain, transformed production through the steam engine, mechanized textile systems, iron manufacturing, and machine tools. Industrialization spread rapidly through Europe, North America, Russia, and Japan during the 19th century, accompanied by electrification, railways, telegraph networks, chemical engineering, and modern urban infrastructure.
The 20th century witnessed unprecedented acceleration. The development of the internal combustion engine, powered flight, radio, radar, antibiotics, nuclear energy, plastics, and electronic computation reshaped global civilization. The invention of the transistor at Bell Laboratories in 1947, followed by the integrated circuit in 1958–1959, initiated the semiconductor age that enabled computers, satellites, telecommunications, and digital networks. The launch of Sputnik 1 by the Soviet Union in 1957, the Apollo 11 lunar landing in 1969, and the rise of the internet from ARPANET after 1969 marked the emergence of planetary technological systems.
During the early 21st century, the convergence of cloud computing, biotechnology, renewable energy, robotics, and machine learning produced a new phase of interconnected infrastructure and algorithmic intelligence. Technologies such as CRISPR gene editing, large language models, reusable rockets, quantum processors, and autonomous systems increasingly blurred the boundaries between the biological, digital, and physical worlds. The present encyclopedia examines this continuous evolution of human technological civilization as an integrated historical process linking invention, science, infrastructure, institutions, and intelligence across all eras of recorded history.
