Futurist Gerd Leonhard breaks new ground again by bringing together mankind’s urge to upgrade and automate everything - down to human biology itself - with our timeless quest for freedom and happiness.

Powerful new technologies enable us to see the details of how our neural systems work. We no longer need to speculate about how genes are expressed or the nature of consciousness. Now, we can understand how the brain functions from the bottom up, how we communicate, form ideas, and behave accordingly.

When people look up into the night sky, the stars seem fixed and immutable, as unchanging as the darkness of space itself, but the truth is that stars are born, live, and die in a never-ending cycle of creation and annihilation. These cycles stretch over such vast spans of time that to short-lived humans, they seem to last forever. No one knows just how many stars there are, but their number is almost beyond comprehension.

O simples fato de vivermos no século XXI já nos faz beneficiários da ciência e dos seus frutos, mesmo que a gente não se dê conta dessa verdade. Os objetos que nos dão conforto, que nos dão prazer, que nos transportam, que nos emocionam, que nos informam (até este audiolivro) só existem da forma como existem por conta dos conhecimentos científicos. O cidadão que ignora fatos científicos básicos pode se tornar presa fácil de curandeiros e charlatões, gente que mente para os outros e, não raro, para si mesma.

Every applicable government agency and almost all mainstream media outlets claim that chemtrails are merely a "conspiracy theory". They say that the lines in the sky are harmless condensation trails and that jet aircrafts have always produced emissions that can linger in the sky for hours as they spread out and form a hazy cloud-cover. They say that anybody who asserts that aircraft are routinely spraying us with toxic materials is crazy. If this is so, then why are we consistently seeing anomalously high levels of toxins in rainwater samples as well as in ambient air samples?

The Pleistocene spans a period from around 2.5 million years ago (mya) to just over 12,000 years ago, and it was an epoch of enormous change on Earth, mainly characterized by climate changes involving fluctuations between periods of extreme heat and long periods of glaciation. This period is commonly known as the Ice Age, despite the fact there were actually a number of separate periods of cold. The Pleistocene Era: The History of the Ice Age and the Dawn of Modern Humans looks at the development of the era, what life on Earth was like, and the origins of archaic humans.

We all know the history of science that we learned from grade school textbooks: how Galileo used his telescope to show that the earth was not the center of the universe; how Newton divined gravity from the falling apple; how Einstein unlocked the mysteries of time and space with a simple equation. This history is made up of long periods of ignorance and confusion, punctuated once an age by a brilliant thinker who puts it all together. These few tower over the ordinary masses, and in the traditional account, it is to them that we owe science in its entirety. This belief is wrong.

The real nature of time is still a mystery, even after thousands of years of philosophers and scientists analyzing it and proposing theories about it. Prophecy has existed for most of humanity’s time on Earth, and there is a lot of reason to think that seeing the future does reveal some of what happens and is about to happen. I also wrote two books on this subject, including the history of prophecy and my own experiences.

Ez a könyv, illetve hangoskönyv arról szól, miféle speciális eszközöket fejlesztett még ki az ember ahhoz, hogy megismerje a világot és benne önmagát, és melyiknek mik a korlátai. Megismerhetjük például a mágia és a hit szerepét világunk megértésében, emellett hallhatunk még két olyan megismerési keretről is, amelyek a jövőben csatlakozhatnak ezekhez. A mesterséges intelligencia és a termékeny nemtudás mind más és más okból jönnek szóba.

"Hace muchos años -1976- estuve en Tucson, Arizona, y en el planetario de la ciudad había un ciclo de charlas de divulgación. Una de ellas me llamó poderosamente la atención. La ofrecía el astrónomo de la Universidad de Arizona, Nick Woolf, y se titulaba "The Universe: I can Feel it in my Bones". El título era tan provocativo que me inspiró para una charla pública que, ya de vuelta en Chile, he dictado durante años: "Somos polvo de estrellas". A miles de jóvenes y no tan jóvenes les he contado lo que yo considero una de las más grandes historias de la astronomía.

Tutti i grandi protagonisti della storia della scienza hanno qualcosa in comune: un'ingenua, entusiastica curiosità, l'abitudine di osservare, la consapevolezza di non possedere a priori la verità. È l'atteggiamento dei "cercatori di meraviglia" che da sempre anima chi tenta di capire il mondo interrogando direttamente la natura (con risultati migliori dopo Galileo, grazie all'uso sistematico del metodo sperimentale). Per mostrare questo approccio in azione, Amedeo Balbi, astrofisico e brillante divulgatore, ha individuato sei grandi domande che potrebbe porre anche un bambino.

¿Qué es un cisne negro? Para empezar, es un suceso improbable, sus consecuencias son importantes y todas las explicaciones que se puedan ofrecer a posteriori no tienen en cuenta el azar y sólo buscan encajar lo imprevisible en un modelo perfecto. El éxito de Google y YouTube, y hasta el 11-S, son “cisnes negros”. Para Nassim Nicholas Taleb, los cisnes negros son parte integrante de nuestro mundo, desde el auge de las religiones hasta los acontecimientos de nuestra vida personal. ¿Por qué no podemos identificar este fenómeno hasta que ya ha sucedido?

La espléndida biografía de Alexander von Humboldt, el héroe perdido de la ciencia y padre de la ecología.

Hay una revolución en marcha, una tecnología prodigiosa que nos va a permitir curar enfermedades, derrotar virus y tener hijos más sanos. A su cabeza está la reciente premio Nobel Jennifer Doudna y sus colegas, protagonistas del nuevo libro de Walter Isaacson.

Meisterblog-Interview 3: Corona-Virus Corona oder die Abkehr vom Olympischen Prinzip - ist der Titel einer Botschaft von Meister Konfuzius, die Ute Kretzschmar empfangen hat. Eine siebenjährige gewaltige Umgestaltung startet gerade in allen Bereichen unseres gesellschaftlichen Zusammenlebens. Die alles entscheidende Frage ist: Wie gestaltet ihr den Planeten und die Gesellschaft humaner, menschlicher, umweltgerechter, freundlicher und herzlicher?

Wie politisch darf Wissenschaft sein? Harald Lesch gibt Antworten. Coronapandemie, Klimakrise - wir leben in einer Zeit vielschichtiger Probleme. Täglich neue Erkenntnisse erschweren uns die Antwort auf die Frage: "Was sollen wir tun?" Hier sind vor allem auch die Naturwissenschaften gefragt: Sie können erklären, Fakten liefern, Orientierung geben, Lösungen bieten. Doch gerade sie stehen neuerdings fundamental in der Kritik. Von Anmaßung der Forscher und Ideologie ist die Rede. Der bekannte Physiker Harald Lesch und der Publizist Klaus Kamphausen appellieren an uns alle.

La scienza moderna non nasce con Galileo e Newton. Le sue origini vanno retrodatate di almeno 2000 anni, alla fine del IV sec. a.C. La Rivoluzione scientifica del XVIII sec. riscopre la Rivoluzione ellenistica di figure come Euclide, Archimede, Erarstotene, Aristarco di Samo e di tanti altri raffinati scienziati. Lo studio della "rivoluzione scientifica", cioè della nascita dello sviluppo scientifico, è indispensabile per la comprensione della "civiltà classica". Inoltre, l'esame del ruolo svolto dalla scienza nella civiltà ellenistica è essenziale.

Le testimonianze raccolte in questo libro, curato da Franco Basaglia e sua moglie Franca Ongaro e pubblicato per la prima volta nel 1975, costituiscono una sorta di ricerca a più voci sul ruolo dell'intellettuale e del tecnico come custodi di istituzioni violente. Attraverso l'approfondimento della funzione che regge le diverse ideologie scientifiche (la psichiatria, la storiografia, la psicologia, la sociologia, la criminologia, la medicina), questi contributi vogliono risalire alla funzione dell'ideologia quale strumento di conservazione del nostro sistema sociale.

Fakten, wissenschaftlich fundiert und eindeutig belegt, sind Gold wert. Besonders dann, wenn Fake News oder Halbwahrheiten die öffentliche Debatte bestimmen und ein sachlicher Diskurs nicht mehr möglich ist. Ob Klimawandel, Homöopathie, Feinstaub oder Erblichkeit von Intelligenz - die Wissenschaftsjournalistin Mai Thi Nguyen-Kim räumt bei diesen und anderen großen Streitthemen mit diesem Missstand auf. Klarsichtig und kurzweilig legt sie dar, was faktisch niemand mehr bestreiten kann und worauf wir uns alle einigen können.

En 1776, les 13 colonies anglaises qui deviendront les 13 premiers États des États-Unis d'Amérique déclaraient leur indépendance, mais l'Angleterre, pour des raisons politiques et économiques, ne leur a octroyé cette indépendance qu'en 1783 après une guerre qui aura duré sept ans.
