    Study Notes

    Breaking Down the Subject

    • Sir Isaac Newton categorized his subject into three subcategories: Length, Time, and Mass.

    Conducting Work

    • Newton conducted his work in a systematic and precise manner.

    Directions

    • Directions mentioned in the text are given as three-dimensional spatial locations.
    • The three dimensions are described as Left and Right, Forward and Backward, and Up and Down.

    Communicating Position

    • A scientist would communicate their position to a fellow scientist using three numbers, specifying their location in three-dimensional space.

    Spatial Locations

    • A third number in a spatial location represents the vertical or up/down direction.

    Origin of Coordinates

    • The origin of coordinates is traditionally given the special set of three numbers (0, 0, 0), representing the reference point.

    Definition of a Meter

    • Initially, a meter was set to be one ten-millionth of the distance from the Equator to the North Pole.
    • In 1960, the standard object used to refine the definition of a meter was the wavelength of light emitted by the krypton-86 atom.
    • In 1983, the final refinement to the meter defined it as the distance traveled by light in a vacuum in 1/299,792,458 of a second.

    Earth's Reference Point

    • The text suggests that the Earth's center is used as the reference point for setting up physical measures like a meter.
