Demokrit - Founder of Induction Logic

Demokrit is considered the founder of induction logic - domyhomework . In doing so, he gave analogy a significant position. He was convinced that one can recognise the truth if one passes from sensual perception and the observation of individual facts to generalisation. According to Demokrit, the generalisation is formed by the intellect, which is based on the perceptual data. He defines the judgement that is formed as a combination of subject and predicate.

With Demokrit's atomistic view, the materialistic view of antiquity had reached its climax. One of his most famous students was Metrodor of chios. Demokrit's atomic theory gained further importance during the Renaissance.

Elementary particles

Elementary particles are the smallest building blocks of matter, of which all substances are composed.

In the past, it was assumed that atoms and molecules were the smallest building blocks of matter. Later, it was discovered that these particles also consist of even smaller components, such as electrons, protons and neutrons - take my online class . Today, these components are called elementary particles. In addition to those mentioned, more than 200 other elementary particles are known today.

These elementary particles are usually divided into three groups according to their mass:

- Light particles (leptons), such as electrons.

- Medium-heavy particles (mesons).

- Heavy particles (baryons), such as protons and neutrons.

It is now known that some of these elementary particles consist of even smaller particles, the so-called "quarks".

For many elementary particles there are particles with the same mass but opposite electrical charge. These particles are called "antiparticles" - chemistry problem solver . They include positrons (antiparticles to the electron) and antiprotons (antiparticles to the proton). When particles and antiparticles meet, "annihilation" occurs. This means that both particles lose their mass and convert completely into electromagnetic radiation.

Light is emitted by light sources in the form of light quanta. These light quanta can also be regarded as particles. They are also called photons.
