Scientific Picture of the World
The world around us is extraordinarily diverse, but its physical organization can be understood as a sequence of levels built from a relatively small set of ingredients, properties and interactions.
Fundamental laws
Space and time, motion, energy, symmetries, conservation laws, relativity and quantum principles.
Matter and fields
Particles, fields, nuclei, atoms, molecules, materials and the collective states of matter.
Stars and galaxies
How gravity builds stars, produces elements, organizes stellar systems and forms galaxies.
Universe
Cosmic expansion, history, large-scale structure and the main open questions of cosmology.
Earth and planets
Earth as a planet, the Solar System, exoplanets, planetary evolution and habitability.
Life
From chemistry to cells, heredity, evolution, ecosystems and the emergence of biological complexity.
Humanity and mind
Human evolution, the brain, cognition, consciousness, language and artificial intelligence.
Scientific knowledge
Facts, hypotheses, models, theories, tests, uncertainty and the changing scientific picture of the world.
