Since Copernicus, humanity has increasingly seen itself as adrift, an insignificant speck within a large, cold universe. Brazilian physicist, astronomer, and winner of the 2019 Templeton Prize Marcelo Gleiser argues that we’re using the wrong paradigm to relate to the universe and our position in it. In this deeply researched and beautifully rendered book, he calls for us to embrace a new life-centric perspective, one which recognizes just how rare and precious life is and why it should be our mission to preserve and nurture it.

Half-bloods with Thierry's skill set are given two options. They can join the conclave's marshal program, or they can pack their bags. Turn down the job offer, and you've just shredded your residency pass for the mortal realm and booked yourself a one-way ticket to Faerie. Texas is the only home Thierry has ever known, and she's not going anywhere. Even if it means following in her notorious father's footsteps as a peacekeeper. But pinning on the badge opens her eyes to the fact sometimes fae need protection too, and that sometimes humans are the real monsters.

¿Qué es la física cuántica? ¿Conoces los misterios más grandes del Universo? La física cuántica es, de todas las teorías científicas, la que quizás más verificaciones y contrastaciones ha recibido al mismo tiempo, y a la vez la más determinante para la vida que llevamos en el siglo XXI. El término “cuántica” proviene de “quantum”, que es la unidad más pequeña que conforma la luz. La física cuántica nos enseña que más allá de todo lo que es material y palpable hay energía.

In Signposts to God, particle physicist Peter Bussey introduces listeners to the mysteries of modern physics and astronomy. Authored in clear, accessible prose, Bussey provides a primer on topics such as the laws of nature, quantum physics, fine-tuning, and current cosmological models. Bussey argues that, far from ruling out a divine creator, modern physics and astronomy present us with compelling signposts to God. The more we know about the cosmos and our presence in it, the more plausible belief in God becomes.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the solar system passed through a disk of dark matter embedded in the Milky Way. In a sense it might have been dark matter that killed the dinosaurs.
