Practical Uses of Math and Science

A collection of brief examples showing how math and science
topics taught in K-12 classes can be used in interesting settings,
including every day life.

  • When a Ruler Is Too Short

    Surveyors are often seen in the middle of the street making careful measurements of angles with their transits, and distances with their steel tapes. For points than can be easily reached, such a survey is convenient. But when the target is inaccessible – a mountain summit or a distant star – known distances can be combined with measured angles to determine a distance or altitude. The method relies on parallax, the way an object appears to move, relative to a more distant background, when viewed from different angles.
