Nine engineering problems and their ingenious solutions.

How do you land a rover on Mars, resolve a perpetual traffic jam or save a herd of caribou from potential extinction? Ask an engineer! Here are nine real-life problems for which engineers designed inventive (and even crazy!) solutions. Each was solved using a different field of engineering—from aerospace and mechanical to the new field of geomatics—along with some awesome math, science and technology skills! A helpful seven-step engineering design process is also featured: define the problem, identify the requirements, develop solutions, design a prototype, test it, improve it and share the idea. What child doesn't love a radical idea? These feats are sure to inspire the natural engineer in all!
