It's a story that begins with the Big Bang and eventually leads to us. Join me as I explore the basic building blocks of the universe… …to the least—manmade elements that last only fractions of a second; strange metals with repellant powers;… So, after all that pulverizing and crushing and weighing and firing, what we're left with is this? Eighteen hundred dollars times…720,000 bucks a truck! The surface mine produces less, about half an ounce per ton. This goes back to the 1800s, the late 1800s, where farmers were looking, actually, for money to plant their next year's crops. We use it for infrastructure; we use it for electronic goods. When times are bad, copper prices tumble, and when times are good, they soar. It's these free-flowing electrons that make metals conductive.

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.

They're the hidden ingredients of everything in our world, from the carbon in our bodies to the metals in our smartphones. The good news is that we haven't finished; there may be still gold hiding in the mix. And, today, it's one of the most widely bought and sold metals in the world. Copper is in wire, electronics and computer chips, plumbing and other building materials. These guys can trade their copper futures; I've got to unload my copper today. In pure metals, the atoms are arranged in orderly rows and columns.

To unlock their secrets, David Pogue, technology columnist and lively host of NOVA's popular "Making Stuff" series, spins viewers through the world of weird, extreme chemistry: the strongest acids, the deadliest poisons, the universe's most abundant elements, and the rarest of the rare—substances cooked up in atom smashers that flicker into existence for only fractions of a second. Yet everything we know, the stars, the planets and life, itself, comes from about 90 basic building blocks,… …all right here, on this remarkable chart: the periodic table of the elements. And we're made, almost entirely, of just a handful of ingredients, including one that burns with secret fire inside us all. The sample, mixed with a lead oxide powder, goes into a furnace heated to 2,000 degrees. Using extreme heat, gold atoms are gradually coaxed away from the powdered rock. Turns out that an ounce per ton is pretty much optimal for the underground mine. The New York Mercantile Exchange is a vital hub in the global metals market, which is pretty good news for me. (Commodities Trader): Oh, this is an old, old business. It's so important that the rise and fall of copper prices provide a snapshot of the health of the entire world economy. Each atom gives up some of its electrons to create a kind of sea of these randomly moving charged particles.

Like all elements, gold is an atom that gets its identity from tiny particles: positively charged protons in the nucleus, balanced by negatively charged electrons all around, plus neutrons, which have no charge at all. It's virtually indestructible, yet also soft and malleable.

The die was cast for his future in racing when he took an agriculture class his senior year in high school where he learned to weld. Always sound great and sometimes we must remember thay arenot all the same some are just well better then others. Casati frames are designed and engineered at their Monza workshops in Italy.A passion dating from 1920 is replicated every day in searching for custom made solutions to accomodate the most demanding cyclist.They use all the materials at hand they even mix up the materials to add some new dimensions.Now not to upset too many people I do feel some materials may be a better then others but they all can have a place.
