AREA
Science, Physics and Chemistry
- Exponential function
  - To know the absorption of X-rays photons in a block of material
    - This lead us to the discover of x-rays or creation of solar panels
  - Radioactive Decay
    - The atomic nucleus is made up of neutrons and protons. Only nuclei with certain ratios of the number of neutrons to the number of protons are stable, all others will change into another combination, giving off a quantum of radiation.
      - These radiations were called alpha, beta and gamma rays
- Scientific notations
  - Scientists and engineers work with very large or small numbers
    - Which are more easily expressed in exponential form or scientific notations
- Population increase or decrease of bacteria in a place
  - Its very important to know the population of bacteria in some places, mostly if is a dangerous bacteria that can damage human health

- Construction
  - Home improvement projects
    - Planning
      - How much to buy and costs
        How many gallons of paint you need for a wall or to paint a whole house
- Engineering
  - Designing
    - calculations of wind resistance and drag in cars or airplanes, pressure and strength of materials
  - How much paint or material it takes to make a fuel tank
    - Equation: pi r 2 + 2 pi r h
- Manufacturing
  - The cost of making boxes or printing, sheet metal parts...
