Does time exist? What is infinity? Why do mirrors reverse left and right but not up and down? In this scintillating collection, Holt explores the human mind, the cosmos, and the thinkers who’ve tried to encompass the latter with the former. With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot.

Operating at the crossroads of memoir, academia, and literature, You Had to Be There offers a fresh, hopeful perspective on the seemingly hopeless subject of climate grief. Over the course of eleven essays, interrogations, and reflections, the author invites listeners to examine the ways in which the media influences our reaction to the events befalling us, not only in how we feel, but in how we behave in the face of such overwhelming circumstances.

An experiment. A declaration. A spiritual awakening. Noted transcendentalist Henry David Thoreau spent two years, two months, and two days chronicling his near-isolation in a small cabin he built in the woods near Walden Pond, on land owned by his mentor and the father of Transcendentalism, Ralph Waldo Emerson. Immersing himself in nature and solitude, Thoreau sought to develop a greater understanding of society amidst a life of self-reliance and simplicity. Originally published in 1854, Walden remains one of the most celebrated works in American literature.

Per tutta la vita, Stephen Hawking si è dedicato a indagare il mondo attraverso la lente della fisica, maneggiando concetti complicatissimi in bilico tra scienza e filosofia: dalla natura dei buchi neri all'origine del tempo, fino alla ricerca di un senso per la nostra esperienza su questo sperduto pianeta, ai confini di una remota galassia sospesa nell'impressionante vastità del cosmo.

Zwei Werke von Henry David Thoreau: Im Jahr 1849 schrieb er seinen weltberühmten Essay über die Pflicht zum Ungehorsam gegen den Staat. In diesem stellte er sich außerhalb einer Gesellschaft, die, obwohl auf den Prinzipien der Freiheit und Gleichheit aller gegründet, nicht in der Lage war, die Sklaverei abzuschaffen. Ungekürzte Lesung (Tracks 1 - 14). Fünf Jahre später folgte Walden oder Das Leben in den Wäldern - seit langem DAS Buch für Aussteiger, Frugalisten, Konsumverweigerer - oder auch ganz einfach nur Naturliebhaber.

La matematica rivista come prassi politica, e non solo come teoria, è un formidabile esercizio di democrazia: come la democrazia si fonda su un sistema di regole, crea comunità e lavora sulle relazioni. Come la democrazia, la matematica amplia ma non nega. Studiando matematica si capiscono molte cose sulla verità. Per esempio che le verità sono partecipate e pertanto i principî di autorità non esistono; che le verità sono tutte assolute ma tutte transitorie perché dipendono dall'insieme di definizione e dalle condizioni al contorno.

Walden or, "Life in the Woods", is, primarily, a reflection upon simple living in natural surroundings. Henry David Thoreau kept a journal during his stay in a cabin beside Walden Pond in Concord, Massachusetts, for two years, two months, and two days, from July 1845 to Sept 1847. The book is based on that journal.

Oxford mathematician and author John Lennox takes a closer look at Hawking's logic regarding what brought the universe into being. In lively, layman's terms, Lennox guides us through the key points in Hawking's arguments - with clear explanations of the latest scientific and philosophical methods and theories - and demonstrates that far from disproving a creator God, they make his existence seem all the more probable.

Für Ian McEwan ist die Geschichte der Wissenschaft eine faszinierende Saga voller intellektuellem Mut, harter Arbeit, tausendfachem Scheitern und kurzen Momenten der Inspiration. Sie ist auch eine Einladung, sich zu wundern und zu freuen. Anhand von Figuren wie Darwin, Einstein oder Turing erforscht Ian McEwan in diesen brillanten Essays das Verhältnis von Wissenschaft und Literatur, Ratio und Glauben und ihren Bezug zu unserer menschlichen Natur.

In the early spring of 1845, Henry David Thoreau built and lived in a cabin near the shore of Walden Pond in rural Massachusetts. For the next two years, he enacted his own Transcendentalist experiment, living a simple life based on self-reliance, individualism, and harmony with nature. The journal he kept at that time evolved into his masterwork, Walden, an eloquent expression of a uniquely American philosophy.
