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.
The number of protons is called the atomic number and it's the fundamental organizing principle of every table of the elements, including this one. They're filled with stats and figures that don't make any sense to the ordinary person. What matters about elements is that they are real physical substances with properties and things you can do with them. I have to say many of these elements look the way you would think—gold looks like gold, silver looks like silver—but not all of them.
Theo makes the point by putting me in touch with the real deal. To make the entire table less abstract, he invites me to lay out the rest of his collection of pure elements. This is a visual representation of every single element that makes up this entire planet and everything on it. As we can clearly see, more than 70 percent of the elements on the table are metals, shiny, malleable materials that conduct electricity. Everything from here on over, including the bottom part, is all metals. And down the middle are these, kind of, halfway in between things, which include, for example, semiconductors, like silicon. The one I was looking at, in particular, was calcium. This is when Theo's collection starts to get really interesting, when he pairs the pure elements with their more familiar forms.
Muller's lab has successfully captured many other images of atoms in gold and computer chips, oxygen, powerful magnets and even glass.
I brought you a couple of hunks of bronze, uh, one of which was knocked off of a bell when it was done and one of which is un-poured. I need an area about the size of a farm, and you've given me the whole of the United States. It's too small for us to see, so we have to mount it on a carrier grid, so we can handle it. Like, like, for one thing, I notice they're really, really grid-like.Out of every hundred bells they pour, 20 or 30 will fail. Our bell resonates with a beautiful tone, and it takes many seconds for the note to die out, thanks to the interplay between copper and tin.Even the best bell makers can't know whether their bronze will be too stiff or too soft, until they pour a bell and strike it. 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.
