Materials and their properties

by Chris Woodford. Last updated: February 6, 2018.
Why do plastic rulers shatter when you flex them while metal ones simply bend? How come you can twist a paperclip two or three times without it breaking but not twenty or thirty times? Why do some cars go rusty faster than others? How do astronauts survive in space without getting boiled by the Sun... or frozen by the lack of it?
These are the kinds of questions that orbit the minds of materials scientists—arguably some of the most important people on Earth. Why are they important? Because from the moment you get up (woken by an alarm clock built around a tiny crystal of ceramic quartz) to the time you go to bed (snoozing soundly on cotton or synthetic-fiber sheets), every single thing you do involves materials of one kind or another. Could we survive without materials? No! When you remember that materials provide everything from the clothes we wear and the food we eat to the energy we use for cooking and keeping warm, it's obvious that civilized human life is impossible without them.
Photo: Miracle material? Look closely at this picture and you'll see a ghostly blue square sitting just underneath the wax crayons: it's a small piece of aerogel, the world's lightest solid. Aerogel is an amazing heat insulator, and here it's protecting the crayons from the blazing heat of the flame. Although discovered decades ago, aerogel has proved very difficult to manufacture as a practical material, so most people have never heard of it and it's yet to make a big impression on the world.
