Leukippos and Democritus; possible also Mochus.
Democritus, in the 5th century, proposed his version of atomism. States that all matter was composed of small indivisible particles called atoms.
The ancient Greeks did not have the concept of atoms as we understand them today, but they did theorize about the nature of matter. Philosophers like Democritus proposed that all matter was composed of small, indivisible particles called atoms. The idea of "hooks" likely stems from their belief that these particles could connect and interact with each other in various ways, much like physical hooks, to form different substances. This metaphor helped explain how different materials could combine and separate, even though their understanding was not scientifically accurate.
A solution is a homogeneous mixture whose particles are too small to reflect or scatter light. A colloid is a heterogeneous mixture containing particles that are small enough to stay suspended but large enough to scatter light.
If I'm not mistaken, it was Montesquieu who argued that a republic could survive only in a small territory.
The Greek philosopher Leucippus (5th century BC) and his pupil Democritus used the word "atom" to mean an indivisibly-small particle of matter. John Dalton (1766-1844) was among the first to use the concept to explain the observed chemical properties of compounds.
The particle theory of matter states that matter is made up of very small indivisible particles that are in constant motion.
Coining of the term "atom" and the idea that matter was composed of small, invisible, indivisible particles.
Around 400 BC Democritus a Greek philosopher theorized that everything was composed of small indivisible particles he called atoms or "atomos".
The first person to describe matter as indivisible particles was the ancient Greek philosopher Democritus, around the 5th century BCE. He proposed that everything in the universe is composed of small, indivisible units called "atomos," meaning "uncuttable." This concept laid the groundwork for the modern atomic theory, although it was not widely accepted until much later in history.
The small spherical solid indivisible model, also known as the atomic theory, was developed in the 5th century BC by the ancient Greek philosopher Democritus. He proposed that all matter is made up of tiny, indivisible particles called atoms.
John Dalton is credited with proposing the atomic theory, which states that all matter is made up of small indivisible particles called atoms.
Democritus, in the 5th century, proposed his version of atomism. States that all matter was composed of small indivisible particles called atoms.
The Greek philosopher who gave the atom its name was Democritus. He proposed that all matter is composed of small indivisible particles called atoms.
Democritus did not believe that matter was infinitely divisible. Instead, he proposed that matter is composed of small, indivisible particles called atoms, which cannot be divided further. He theorized that these atoms are the fundamental building blocks of all matter, and while they can combine in various ways to form different substances, the atoms themselves remain indivisible. This idea marked a significant departure from the notion of continuous matter.
Both Dalton and Democritus proposed that matter is made up of indivisible particles called atoms that are different in size and shape. They also believed that atoms are in constant motion and can combine to form different substances.
The English scientist who proposed that all matter is made up of indivisible particles called atoms was John Dalton. He introduced his atomic theory in the early 19th century, which laid the foundation for modern chemistry.
