    5 inventions of the modern age

  • Thermometer

    It was invented in the year 1593 by the astronomer, engineer and philosopher Galileo Galilei. At the beginning it was called a thermoscope, this was the first way to measure the variation of temperature using a thermometer that contained water with a few drops of alcohol.
    Advantages: it was possible to determine if a person was sick, great comfort and ease of use and made with ecological materials.
    Disadvantages: high time needed to obtain the correct measurement, risk of breaking.
  • Telescope

    In 1608, Hans Lippershey created the telescope, a new device that allowed objects that were at a great distance to be observed in detail. Since then this contraption has been improved many times, once by Galileo to adapt it to the study of astronomy.
    Advantages: the opportunity to see things far away, its small size and to see the phases of the moon.
    Disadvantages: demonstrate the imperfections of the moon and the sun, little resistance and contradict the theory of geocentrism.
  • Submarine

    The submarine was created in 1620 by Cornelius Jacobzoon Drebbel. At first this invention worked underwater with oars. It was an English engineer who achieved this invention by placing a wooden roof over a fishing boat, covering everything with leather and grease to better waterproof the surface of the submersible.
    Advantages: able to observe the seabed, non-polluting materials and resistance.
    Disadvantages: Works with manual labor, small size, and unsafe.
  • Calculator

    William Oughtred designed the slide rule to improve and make mathematical calculations easier. In 1623, thanks to this calculation rule, the German Wilhelm Schickard built the first automatic calculator. Years later this was improved by Pascal, creating a gear-based calculator.
    Advantages: it was small, manageable, made of metal
    Disadvantages: you couldn't do addition and subtraction directly, you can only add and subtract and it was slow.
  • Pencil

    It was created in 1792 by Jacques-Nicolás Conté, a French engineer who worked at the French court. What he did was mix the graphite with clay, harden it and surround it with cedar wood, making it the most similar invention to pencils today.
    Advantages: easy to use, low economic outlay and easy to transport and communicate.
    Disadvantages: poorly resistant materials, difficult creation and wear of the graphite tip.
