1. Stone Age
    1. 8701 BCE - 3300 BCE
      1. This is a prehistoric period of human culture, it is defined by the used of stone for early technologies necessary for survival.
        1. Major innovations of the time were stone weapons like knives. This invention carried into the future periods; a modern example of a stone knife is a regular kitchen knife, or a Swiss army knife, now usually made of different metals instead of stone.

  2. Bronze age
    1. 3000 BCE - 1200 BCE
      1. This age is mainly defined by the beginning of our written history, and the start of mixing metals to create alloys.
        1. An innovation of that time are writing materials, like ink. -- invented during the 4th century BCE in India. -- writing with ink is still widely used today, for example writing with pens on documents or at school.

  3. The Iron Age
    1. 1200 BCE - 600 BCE
      1. In this period people started to use iron and steel for crafting tools; ores, elements, and smelting were discovers for making metals with different qualities, like steel's strength, and bronze's resistance to rust.
        1. A discovery of that time is steel, which was first founded in Africa, Asia, and Europe. We see steel being used to build many technologies today, from infrastructure to smaller technological systems due to its desirable strength.
  4. The Middle Ages
    1. 476 BCE - 1453 BCE
      1. The beginning of the middle ages is marked by the fall of the western Roman Empire, and the end of it by the fall of the eastern Roman Empire.
        1. A technological advancement of this time is the introduction of mechanical clocks in northern Italy/southern Germany. These mechanical clocks influenced the invention of smaller clocks like the ones in hand watches and the round clocks hanging in practically all classrooms.

  5. Renaissance Period
    1. 1300 - 1600
      1. This period is defined by the growth of arts and literature works in Europe.
        1. Leonardo da Vinci's(1452-1519)(Italy) drawings and painting are innovations of this time period; they were the inspiration for today's ways of designing technical drawings. Technical drawings convey how objects function and are constructed, and are used in many fields such as engineering and electrical work.
  6. Industrial Revolution
    1. 1750 -1914
      1. This time period is defined by people moving from the country side, where they supported themselves by farming, to cities, where they started working jobs in the technological fields.
        1. A major invention of this time period is the telephone, invented in 1876 by Alexander Graham Bell in the USA. This new technology had an unimaginable impact on today's world. This invention later lead to the innovation of smartphones, like the ones so many people all over the world have today.

  7. The Atomic Age
    1. July 16, 1945
      1. This period is defined by the study of the atom, leading to the invention of atomic weapons and nuclear power.
        1. Nuclear energy was developed in this time period by Enrico Fermi, an Italian physicist, in 1951. Today, nuclear energy is used in many ways, like providing electricity for homes and business, powering desalination plants, and providing heat for metal refining, among many others.
  8. The Space Age
    1. October 4, 1957
      1. The Space Age is defined by activities related to space exploration and space technology, and its beginning is marked by the space race, when the USSR successfully launched the first satellite.
        1. The main innovation of this time period is the invention of the rockets, the first successful rocket was launched by the USSR, in present day Kazakhstan, in 1957. Eventually engineers and scientists built on this innovation, so a modern example of the first satellite is the international space station.
  9. The Information Age
    1. 1970s
      1. The information age is characterized the the wide use of digital technology and the grow of the internet.
        1. One of the major inventions of this time period is the internet; which impacts our everyday life, for example, me using the internet to do school.(exactly who/when/where invented the internet was not stated in the article, and I couldn't find a concise answer either)
  10. The AI Age
    1. This period will be defined by the widespread use of artificial intelligence, and the implementation of it into our daily lives. I believe that biotechnology will advance in this period and be one of the larger innovations. The reasoning behind this is that AI is already being largely used, especially in the form of robotics, among other areas. Robotics is already taking over many fields that once required human labor. Similarly, biotechnology is making great advancements, and I believe that even greater innovations in that field will follow.
