Can we crack the code to build the world of the future? By digging, these guys are hoping to strike it rich. I'm on a quest to understand the basic building blocks of everyday matter. These symbols represent the atoms that make up every single thing in our universe: 118 unique substances arranged on an amazing chart that reveals their hidden secrets to anyone who knows how to read it. It turns out that nature has concealed thousands of pounds of the stuff under billions of cubic feet of earth. Every day she receives hundreds of samples of earth taken from the mine. …then pulverized to the consistency of baby powder. But two rows above gold is another metal of antiquity that looms large in our lives: copper; symbol Cu; atomic number 29—29 protons, 29 electrons. Bronze helped to spur global trade, and, once forged into tools and weapons, it played a defining role in the empires of antiquity. I'm here because they're about to cast several bells. This rock face is about a quarter mile below the surface, and, according to John Taule, it's loaded with gold, somewhere. That's where Gayle Fitzwater and the assay team come in. I think I've seen one of these machines at Starbucks. It is, perhaps, the most emotional of the elements. Tin added in small amounts to copper makes bronze, the first manmade metal alloy. This is The Verdin Company, a 170-year-old family-run business in Cincinnati, Ohio.Where do nature's building blocks, called the elements, come from? Her job is to figure out how much gold is in them there rocks. I don't see any more rocks in here, but the bad news is, I don't see any gold in here, either. Final steps: cool and clean the bars, stamp them with their unique serial numbers and their weights. The ancients first learned how to heat rocks to extract copper, at least 7,000 years ago. Traders in New York, London and Shanghai buy and sell more than 20 million tons a year. Copper has been prized for millennia for its unique properties: it conducts electricity better than any metal except silver; it's malleable and has a moderate melting temperature; it even scares away bacteria. Even with all the other modern materials available, they still choose bronze. Hasn't something better come along, after all these years? The quality of the sound depends on the atomic structure of the material.

Join me on my Hunt for the Elements, right now, on NOVA. They tell me that so much money flows out of this place, it's like a gold mine. It's a journey that dives deep into the metals of civilization, marvels at the mysteries of the extremely reactive, reveals hidden powers and harnesses secrets of life, from hydrogen to uranium and beyond.To see what it takes to get something bigger than that tiny bead, I visit the processing plant where the ore ends up. Here too, extraction begins with crushing, in these huge tumblers. So what the farmers would do is they would say, for example, "David, you loan me some money, okay? I can hardly think of anything that doesn't have either a tiny bit of copper or lots of copper. When placed in a circuit, the negatively charged particles line up and flow as an electric current.
