Gold is not what we think. It is usually discussed in the context of wealth and art but this book has a broader subject, so fundamental that it has been largely unremarked. Informed by a mass of recent discoveries and a South American indigenous perspective, it offers a new way of understanding the history of civilization. Gold has been coinage, treasure and adornment. But it has been much more, as the hidden driver of wars and revolutions, the rise and fall of empires and the transformation of societies. As the sun traveled east to west across the sky, gold, incorruptible and corrupting, flowed west to east, hand to hand across the world. That flow has brought empires to grow and collapse and driven plunder, conquest and colonization. It brought about wars and revolutions, empowered new forms of arts and science and created the capitalist consumer economy that dominates us now. All the gold people ever shaped still exists, shining as new; it can be mislaid but never decays. Right from its first appearance on the west shore of the Black Sea, long before the rise of Egypt and Mesopotamia, gold crowned the first proto-king. Ever since, it has been regarded as value incarnate with transcendental power. The quantity we take has been increasing steadily for 6,500 years. Now extraction accelerates. Our gold mountain has doubled in the last fifty years. Yet its price increases faster. While the quantity doubled, its buying power multiplied by six. What does gold do that makes us want it so much? As Alan Ereira reveals in this skilfully woven narrative, gold is the hidden actor that shapes our story.

I feel very honoured to have been asked to write a brief foreword for this book on QRD-RLS Adaptive Filtering–asubjectwhichhas been close to my heart for many years. The book is well written and very timely – I look forward personally to seeing it in print. The editor is to be congratulated on assembling such a highly esteemed team of contributing authors able to span the broad range of topics and concepts which underpin this subject. In many respects, and for reasons well expounded by the authors, the LMS al- rithm has reigned supreme since its inception, as the algorithm of choice for prac- cal applications of adaptive ltering. However, as a result of the relentless advances in electronic technology, the demand for stable and ef cient RLS algorithms is growing rapidly – not just because the higher computational load is no longer such a serious barrier, but also because the technological pull has grown much stronger in the modern commercial world of 3G mobile communications, cognitive radio, high speed imagery, and so on.

After the congressional session ends, Jefferson leaves Washington and goes home to Monticello, where his ailing daughter Mary dies on 17 April. Among the letters of condolence he receives is one from Abigail Adams that initiates a brief resumption of their correspondence. While in Virginia, Jefferson immerses himself in litigations involving land. Back in the capital, he finds that he must reconcile differing opinions of James Madison and Albert Gallatin to settle a claim for diplomatic expenses. He corresponds with Charles Willson Peale about modifications to the polygraph writing machine. He prepares instructions for an expedition to explore the Arkansas and Red Rivers. William Clark and Meriwether Lewis send him maps and natural history specimens from St. Louis. Alexander von Humboldt visits Washington. News arrives that a daring raid led by Stephen Decatur Jr. has burned the frigate Philadelphia to deprive Tripoli of its use. Jefferson is concerned that mediation by Russia or France to obtain the release of the ship’s crew could make the United States appear weak. Commodore Samuel Barron sails with frigates to reinforce the squadron in the Mediterranean. Jefferson appoints John Armstrong to succeed Robert R. Livingston as minister to France and attempts to persuade Lafayette to move to Louisiana. In Paris, Napoleon is proclaimed Emperor of the French. Jefferson has “brought peace to our Country and comfort to our Souls,” John Tyler writes from Virginia.
