• Science communication
• Knowledge society

Early Methods of Knowledge Preservation

• Pythagoreans (4th century BC): This sect of astrologers, mathematicians, philosophers, and musicians believed numbers were the essence of all things. They used mystic ceremonies and rituals to document and share their discoveries. Secrecy was paramount, with members sworn to silence under threat of death.
• John Dee (Renaissance): An English magician, alchemist, astrologer, astronomer, and mathematician who collected secrets from navigators across Europe. He faced social stigma due to the era's perception of certain knowledge as heretical or demonic. His experience, texts, and inventions were fundamental for Queen Elizabeth I and the development of the British fleet and empire.

The Mathematization of Knowledge

• Galileo Galilei (16th-17th century): Broke with Aristotelian and scholastic models, pioneering the mathematization of knowledge and experimental science.
  • Siderus Nuncius (1610): Described an extensive compilation of previously unrecorded stars and the discovery of Jupiter's four moons, along with his invention, the Galilean telescope.
  • Dialogues on the Two Chief World Systems (1629): Written in Italian (not Latin), making it accessible to a wider audience. Presented as a dialogue between Salciati (defending the Copernican system) and Simplicio (defending the Ptolemaic system). It established revolutionary ideas about the Earth's movement around the sun and criticized existing knowledge. The book was banned by the Church in Rome, leading to Galileo's condemnation by the Inquisition. The anecdote about Galileo saying "and yet it moves" after his trial is likely untrue.

The Industrial Revolution and the Rise of Technoscience

• Industrial Revolution (18th century England): Marked by the steam engine and inventions applied to agriculture, transport, and mining. Scientific knowledge became popular among the wealthy. The Great Exhibition in London (1851) showcased major inventions. Countries that promoted science and technology became economic powers.
• Mid-20th Century: North American technoscience became the most advanced, demonstrated by the Manhattan Project and the atomic bomb.
  • Manhattan Project: Led by Robert Oppenheimer, with Enrico Fermi and Richard Feynman as managers. Aimed to defeat Hitler by building the atomic bomb first. The bombs were used against Japan in Hiroshima and Nagasaki, killing over 220,000 people. This event led to a negative perception of science.
  • Sputnik (1957): The Soviet Union launched Sputnik I, the first artificial satellite, followed by Sputnik II with the dog Laika. This triggered panic in the United States, leading to the creation of NASA in 1958.

Science Communication and the Knowledge Society

• NASA: Created as a research institution and a science dissemination machine.
  • Apollo 11: The moon landing was a technological feat reaching over 500 million people worldwide and shaping North American identity.
• Carl Sagan and Isaac Asimov: Pioneered new ways to communicate knowledge to the public. Many countries initiated public policies to promote research and scientific knowledge.
• Late 20th Century: The internet and the "knowledge society" emerged, valuing information and knowledge (including scientific, mathematical, and statistical) as the greatest wealth.
• CERN (European Council for Nuclear Research): Located on the border between Switzerland and France, it houses the Large Hadron Collider, a 27km circular tunnel used to accelerate particles to near light speed and study their collisions. CERN has the most important science communication program in the world, involving physicists, engineers, communicators, designers, artists, and educators.
  • Higgs Boson (2013): The detection of the Higgs particle, responsible for giving mass to everything, was widely publicized and considered the beginning of a new paradigm in physics.

The Future of Science

• 21st Century: Scientific projects focus on artificial intelligence, renewable energies, telecommunications, and space travel.
  • Virgin Galactic: Developing vehicles for space tourism, offering brief periods of zero gravity and safe re-entry.
  • SpaceX: Elon Musk's company, developing recyclable rockets like Falcon I and II for cargo transport.
• The future is exciting but uncertain, with science advancing alongside environmental challenges caused by industrial pollution.
