Hazard Symbols

Air Pollution from Burning Fossil Fuels

Complete combustion - the fuel reacts completely with oxygen, e.g.:

Incomplete combustion - the fuel only partly reacts with oxygen, e.g.:

hydrocarbon + oxygen → carbon dioxide + water + carbon monoxide + carbon (soot)

Impurities in fossil fuels, such as sulfur, also react with oxygen when heated:

sulfur + oxygen → sulfur dioxide

The foremost characteristic of the Renaissance is the rebirth of the classics (Greece and Rome).

If during the Middle Ages God was at the center of everything, now it is the contrary. Humans are at the center of everything (anthropocentrism).

Reasoning, not faith, is what guides life.

Art is seen as an end in itself (not something to please God) and its goal is to achieve the ideal form of beauty based on the harmony and proportions found in nature.

All artistic expressions found inspiration in old Rome. The only exception was music, which had to find its own style far from medieval music.
