Quarantined

Michael Williams followed in his father’s footsteps, and joined the UEDF, the United Earth Defense Force, when he turned eighteen. His one year mission is over, he has a five weeks’ leave before his next assignment, and he’s looking forward to seeing Katy.Of course, planning is what you do when life is happening around you, and the aliens finally make their move, and Michael is recalled. Instead of being sent to fight in the war like he’d expected, they have another little mission first. A trip to Eta Cassiopeiae A, a colony that isn’t in the history books, full of humans that shouldn’t exist. The planet and system is quarantined, for good reason, but desperate times call for desperate measures. Chances are, if they’re to manage surviving the aliens, they’ll need all the help they can get.Lt. Commander Michael Williams is in for quite a few surprises, and is about to have his eyes opened to the truth, and the truth isn’t at all pleasant…

Quantum Man: Richard Feynman’s Life in Science

Perhaps the greatest physicist of the second half of the twentieth century, Richard Feynman changed the way we think about quantum mechanics, the most perplexing of all physical theories. Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits. An immensely colorful persona in and out of the office, Feynman revolutionized our understanding of nature amid a turbulent life. Krauss presents that life—from the death of Feynman’s childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon—as seen through the science, providing a new understanding of the legacy of a man who has fascinated millions. An accessible reflection on the issues that drive physics today, *Quantum Man* captures the story of a man who was willing to break all the rules to tame a theory that broke all the rules.

Quantum Economics

A decade after the financial crisis, there is a growing consensus that economics has failed and needs to go back to the drawing board. David Orrell argues that it has been trying to solve the wrong problem all along.

Economics sees itself as the science of scarcity. Instead, it should be the science of money (which plays a surprisingly small role in mainstream theory). And money is a substance that turns out to have a quantum nature of its own.

Just as physicists learn about matter by studying the exchange of particles at the subatomic level, so economics should begin by analysing the nature of money-based transactions. Quantum Economics therefore starts with the meaning of the phrase “how much’ – or, to use the Latin word, quantum.

From quantum physics to the dualistic properties of money, via the emerging areas of quantum finance and quantum cognition, this profoundly important book reveals that quantum economics is to neoclassical economics what quantum physics is to classical physics – a genuine turning point in our understanding.

Quando Sorge La Luna: Un Antico Viaggio Per Gordon Spada (Gordon Spada, #5)

Per molti secoli gli storici hanno convinto il mondo che sia stato Cristoforo Colombo, nel 1492, a scoprire l’America. Tuttavia non sembra pensarla così il misterioso conte Dunbar. E’ stato lui a chiamare Gordon Spada in Scozia per aiutarlo a trovare le prove di quella che potrebbe essere la notizia più sconvolgente del secolo. La verità è inquietante: un nobile scozzese, con l’aiuto di alcuni navigatori veneziani, sarebbe arrivato in America ben cento anni prima di Colombo, e avrebbe portato con sé qualcosa d’incredibile per dimostrarlo. Il segreto sarebbe stato poi abilmente sepolto nella Cappella di Rosslyn.
In questa avventura Gordon Spada si troverà invischiato in una trama mozzafiato che rischierà seriamente di mettere a repentaglio la sua vita e la sua libertà, e anche i nervi della sua giovane assistente francese Marion.
Un’organizzazione segreta di nobili famiglie scozzesi, una misteriosa donna indiana, l’assassinio di un membro della House of Lords e gli incredibili enigmi nascosti nella Colonna dell’Apprendista…
Questi sono solo una parte degli intricati eventi che Gordon Spada e la sua fedelissima assistente dovranno riuscire a risolvere in questa nuova avventura che trasporterà il lettore nelle fitte pieghe di un enigma che nessuno ha mai avuto il coraggio di raccontare.
IL PROTAGONISTA
Gordon Spada non è un semplice mercante d’arte della piccola Firenze, ma qualcosa di più. Spada è un uomo strano, per certi versi inquietante. E’ un solitario, un esteta pieno di ossessioni, che alla compagnia degli esseri umani preferisce di gran lunga quella dei dipinti e delle opere antiche. Ma è anche un avventuriero. Da anni, infatti, va alla ricerca di preziose e perdute opere d’arte per soddisfare le brame dei facoltosi collezionisti che a lui si rivolgono. Non si arrende mai, sempre pronto a mettere a repentaglio ogni cosa pur di fare luce sui misteri che pretendono di restare nascosti ai suoi occhi e – soprattutto – pur di ottenere la ricompensa finale.
