Welcome to the Physical Ecology Group at the University of Lincoln
Although organisms obey the same physical laws as inanimate objects the evolutionary implications of these laws are often neglected. Physical factors influence the fitness value of traits and play an important role in the course of evolution. These are the areas of investigation that interest us.
High-speed video is wonderful for appreciating fluid motion in ways we can’t on our own. In this video from Warped Perception, we see what happens when a vibrating tuning fork is lowered into water. The tines of the tuning fork create a spray of tiny droplets, reminiscent of what happens in ultrasonic atomization or when blowing through an immersed straw. The ejected droplets fall slowly back onto the disturbed surface; many of them bounce rather than coalescing. This is because the surface’s vibration pushes the drops aloft again before the air layer separating the drop from the surface has the time to drain away. (Video credit: Warped Perception)
