This episode introduces us to concepts involved in remotely observing forests as we discuss Patrick's research with Tropical Dry forests. Learn about how shooting trees with lasers can help us monitor trees while we also touch on other topics like jaguars, surfing biologists, and radio waves. Patrick highlights the importance of checking the health of these forests and the interdisciplinary approaches that are taken to analyze and understand all of the data involved. We also continue discussions from last week about the behaviour of waves when pouring a cup of coffee. Finally, we discuss how the modern pocket watch came to be during a time when people were exploring the world, and trying to figure out where they were.
