The world is wonderful, both figuratively (i.e. cool) and literally (i.e. capable of inspiring wonder). But you need to know where to look. Let me give you one example: the spider web. Next time you see one, rather than walking past it or brushing it away, stop for a minute and examine it. Think about how the web needs to be sticky for the prey, but not sticky (or at least less sticky) for the spider. Think about how the spider decides where to build the web. Think about how the spider spins the web in mid-air, without equipment or scaffolding. Notice the difference between the silk in the radial spikes and the silk in the rest of the web, and think about the design requirements that might account for such differences in physical properties (strength, elasticity, etc). See if parts of the web have reeled-in surplus thread to prevent prey from ripping straight through the web. Check back the next day to see if the spider has repaired or even entirely rebuilt the web. And think about how the spider is locked in a co-evolutionary escalation with prey whose ancestors were selected for over millions of years for their ability to avoid getting caught in just such a web. Admittedly, spiders are murderers. But they're also real estate developers, architects, materials scientists, acrobats, and engineers.
