Why isn't wood weaker that it is? Why isn't steel stronger? Why does glass sometimes shatter and sometimes bend like spring? Why do ships break in half? What is a liquid and is treacle one? All these are questions about the nature of materials. All of them are vital to engineers but also fascinating as scientific problems. During the 250 years up to the 1920s and 1930s they had been answered largely by seeing how materials behaved in practice. But materials continued to do things that they...

Yet because we take the daily reality of money...

In the aftermath of World War II, a succession of mass supernatural events swept through war-torn Germany. A messianic faith healer rose to extraordinary fame; enormous crowds traveled to witness apparitions of the Virgin Mary.

Today, a growing coalition of “Beaver Believers”—including scientists, ranchers, and passion...
