  • Robert Hooke
    • Hooke's Law
      • The extension of a spring is proportional to the force applied to it,
        • can also be written as F=kx
          • F is the load of the force stretching the spring
          • k is the stiffness of the spring
          • x is the extension of the spring
    • natural philos-opher an early scientist
    • wrote a book called micrographia
      • detailed drawing of things he saw
    • discovered cells
      • Van Leeuwenhoek
        • discovered "pr-otozoa". The single-celled organism
        • improved the microscope and laid foundation for microbiology
      • 1665
  • intrested in springs
    • Great inventor

    • useful in making weighing machines
      • very sensitive and accurate to weight
    • realised how spiral springs could be used to control a clock or even a wristwatch.
