Scientists
Meet the people behind major discoveries.
SpaceGalileo Galilei — the man who turned a telescope toward the sky and changed how we see the world
Galileo did not invent the telescope or first propose that Earth moves. His observations, experiments and disputes with authority changed how we test claims about nature.
PhysicsEdward Teller: the genius who opened the thermonuclear age
From quantum physics and flight from Nazism to the hydrogen bomb, the Oppenheimer hearing and “Star Wars”.
TechnologyNikola Tesla: the motor that changed the electrical world
From Smiljan to rotating magnetic fields, AC patents and the boundary between working inventions and grand plans.
PhysicsAlbert Einstein: from light quanta to curved spacetime
How a patent clerk changed our understanding of light, time and gravity, and how the ideas were tested.
PhysicsArchimedes: buoyancy, levers and ideas ahead of their time
Behind the “Eureka” story stand rigorous geometry, problems of balance and questions that still matter in physics.
Living worldCharles Darwin: how did evolutionary theory emerge?
From notebooks aboard the Beagle to natural selection: how the idea that transformed biology developed, and what it actually says.
PhysicsHow did Faraday discover electromagnetic induction?
An 1831 experiment showed that a changing magnetic field can produce an electric current.
