AETN Exploration Wednesdays Return - Pelicans, Making Stuff
Posted on 19 Sep 2012
First, with Â“Nature: Outback PelicansÂ” we travel to the driest place on the worldÂ’s driest inhabited continent Â– the Australian Outback. And while weÂ’d normally expect specifically adapted creatures, like the kangaroo, to thrive … but not water birds. Yet, once every 10 years, the landscape changes. With the great rains, dried-up river beds are invigorated, and the rushing streams flow inland to create AustraliaÂ’s largest lake. As a result, more than 100,000 pelicanÂ’s Â– a third of the continentÂ’s population Â– flock in to the disappearing lake. ItÂ’s a fascinating sight!
Amazement continues as we speculate smaller wonders on NOVA at 8 and 9 p.m. In the first episode, host David Pogue invites us to look at the ways that science and nature create Â“strong stuff.Â” From spider silk to carbon nanotubes, weÂ’ll explore the science of strength to determine what material is really the strongest Â“stuffÂ” on earth. In Â“Making Stuff Smaller,Â” we switch gears and microfocus on how, in the information age, smaller is better. WeÂ’ll follow David to learn about transistors, microchips, laptops and cellphones have achieved their triumphs of the tiny. Then, we delve even deeper as Pogue profiles the latest in high-powered nano-circuits and micro-robots that may hold the key to saving lives and building materials from the ground up.
