Description

Scale – dealing with the miniscule to the massive, over milliseconds to millennia – is central to all the sciences.

In this course, Scales in space and time, you’ll go to the absolute limits of what can be measured – all through a study of an oak tree! By studying it you will be introduced to concepts in physics, chemistry, biology and life-sciences, and Earth and environmental sciences. Across these multiple disciplines you will meet time scales that include ages, durations and rates, and size scales including distances in three dimensions, which underpin areas and volumes.

Course learning outcomes

After studying this course, you should be able to:

  • Demonstrate an understanding of the range of size and time scales encountered in science
  • Collect information from multiple sources
  • Use maths skills to convert between units and scales
  • Describe how processes on one scale can impact processes at another scale.
