5 days ago · Democritus (born c. 460 bce —died c. 370) was an ancient Greek philosopher, a central figure in the development of philosophical atomism and of the atomic theory of the universe. Knowledge of Democritus’s life is largely limited to untrustworthy tradition. It seems that he was a wealthy citizen of Abdera, in Thrace; that he traveled widely ...

3 days ago · Definition: Atoms. Atoms are the basic units of matter, and they can be used to understand the physical and chemical properties of the periodic table elements. John Dalton used some relatively simple scientific equipment to study matter. His experiments eventually helped him publish a landmark paper in 1803.

The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
3 days ago · The double-slit experiment is an experiment in quantum mechanics and optics demonstrating the wave-particle duality of electrons, photons, and other fundamental objects in physics. When streams of particles such as electrons or photons pass through two narrow adjacent slits to hit a detector screen on the other side, they don't form clusters based on whether they passed through one slit ...
