Professor: Today we're going to start our unit on biomimicry. This is a fascinating field where we look to nature to solve human problems. Essentially, biomimicry is innovation inspired by nature. A classic example is how the front of a high-speed train was redesigned to mimic a kingfisher's beak. This simple change, inspired by a bird, significantly reduced the train's noise and increased its efficiency. We'll explore more examples like this over the next few weeks.
