Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

Tools

Let us continue our journey through the forest and have a look at a tree stem that is laying in the sand (image below).

Many trees in moderate climates make one growth ring each year, with the newest adjacent to the bark. Hence, for the entire period of a tree’s life, a year-by-year record or ring pattern is formed that reflects the age of the tree and the climatic conditions in which the tree grew. If you wanted to investigate and count the tree rings you can use your eyes and count. Another way is to take a magnifying glass and examine each detail. Depending on the scope, you determine the tool you need. This is very important, and you should be aware of what you need in order to see and collect the relevant data.
