  • Isaac Newton

    Isaac Newton
    21 year old Newton created the White Light Spectrum. The White Light Spectrum is the way of seeing the colors of the rainbow by prisms. This helped many people because it helped create different and new inventions in the scientific world. A.K
  • Isaac Newton

    Isaac Newton
    34 year old Isaac Newton discovered the force of gravitation. Gravitation is the force of how objects on Earth stay in place instead of float into the air. This discovery influenced many others to prove it wrong or right. Today we still go by this discovery. A.K

    37 year old Newton created the Heliocentric Theory. This theory is the study of how the earth and the planets revolve and rotate.

  • Isaac Newton

    Isaac Newton
    44 year old Isaac Newton created the 3 Laws of Motion. These laws state that an object in motion will stay in motion, an object at rest will stay at rest and for every action there is an equal and opposite reaction. This law is still being used today. This law helped other scientist create other theories about motion. A.K
