A close look at chemical elements, the basic building blocks of the universe. Where do we get them, what do we use them for and how do they fit into our economy?
A close look at chemical elements, the basic building blocks of the universe. Where do we get them, what do we use them for and how do they fit into our economy?
Why do we value this practically useless metal so highly? And does it bring out the worst in human nature?
In a second look at this most coveted of metals, Justin Rowlatt hears both sides of the age-old argument. Swiss investor and gold enthusiast Marc Faber explains why he keeps gold bars tucked away at his home in rural Thailand. Meanwhile financial advisor and Big Picture blogger Barry Ritholtz teases goldbugs for succumbing to what he considers their very human irrational tendencies.
Plus, we hear from Bandana Tewari of Vogue magazine about why her home country of India will always be besotted by the bling of gold.
And here's a bonus for what is the penultimate programme in the Elements series. This podcast contains 10 gold-themed songs. If you think you can name some of them, then tweet your guesses to Justin at @BBCJustinR. Get them all right, and Justin might even give you a prize.
