We have mapped the surface of Mars with greater precision than the floor of our own oceans. We predict the weather on Jupiter but cannot say when the next earthquake will strike. We speak of the planet’s future with the confidence of prophets—yet we do not know where the water came from, why heavy elements sit in the crust instead of sinking to the core, or how the first living cell assembled itself from dust. Dust and Time is a sweeping, unflinching exploration of the vast territories of geological ignorance that modern science has papered over with confident models and apocalyptic headlines.

Universe 25 meets quantum physics. In 1968, behavioral researcher John B. Calhoun built a perfect world for mice. Unlimited food, unlimited water, no predators, no disease. Paradise. The mice thrived at first. They bred, built social groups, and formed a functioning colony. Then everything fell apart. Males became violent without reason. Females abandoned their young. A group Calhoun called the beautiful ones withdrew completely, spending their days grooming themselves in isolation while their world crumbled around them. Reproduction stopped. Social bonds dissolved. Every single mouse died.

In the Preface to CANADA AND OTHER POEMS BY T. F. YOUNG. (1887) he writes "Pedantic critics may find fault with my modest productions, and perhaps justly, in regard to grammatical construction, and mechanical arrangement, but I shall be satisfied, if the public discern a vein of true poetry glittering here and there through what I have just written."

LibriVox volunteers bring you 15 recordings of A Snow Storm by T.F. Young. This was the Weekly Poetry project for January 6, 2019. ------ Pedantic critics may find fault with my modest productions, and perhaps justly, in regard to grammatical construction, and mechanical arrangement, but I shall be satisfied, if the public discern a vein of true poetry glittering here and there through what I have just written. The public are the final judges of compositions of this sort, and not the writer himself, or his personal friends. It is they, therefore, who must decide whether these humble attempts ...

At 4:00 a.m. on March 28, 1979, a serious accident occurred at the Three Mile Island 2 nuclear power plant near Middletown, Pennsylvania. The accident was initiated by mechanical malfunctions in the plant and made much worse by a combination of human errors in responding to it. During the next 4 days, the extent and gravity of the accident was unclear to the managers of the plant, to federal and state officials, and to the general public. What is quite clear is that its impact, nationally and internationally, has raised serious concerns about the safety of nuclear power. This Commission was ...

The purpose of the study as here presented is to approach the Middle Ages from a new point of view, by showing how the thought of the period, metaphysics included, is intimately connected with the whole round of Western civilization to which it belongs. My work represents simply an attempt to open the way; it makes no pretense to exhaustive treatment of any of the innumerable problems involved in so vast a subject. - Summary by Preface

Where science meets the edge of human understanding.Each week, media moderator Anna Dean and renowned physicist Professor Halloway sit down for an unfiltered deep dive into the ideas reshaping our world — from the mysteries of consciousness and the frontiers of quantum physics, to the explosive rise of artificial intelligence and the technologies redefining what it means to be human. This is not a surface-level conversation. This is science, philosophy, and curiosity — unleashed. Topics discussed in depth: Ai, Conciousness, Quantum Immortality,Ghosts, NDEs, Quantum Computing, Reality and ...

Bertrand Russell gave the Lowell Lectures in March and April of 1914; these lectures produced 'Our Knowledge of the External World'. Russell attempts to analyze the relationship of the crude data of our senses to the notions of physics such as space, time, and matter. Russell takes his analysis to illustrate the method of logical analysis used to such wonderful effect by thinkers in the late nineteenth-century to the notions of continuity, infinity, and the infinitesimal. These analyses effected a new epoch of clarity in the philosophy of mathematics; Russell hopes that a similar new age of ...

Queen Elizabeth the First of England, the Grand Turk at Constantinople, and an organ builder named Thomas Dallam—quite a trio. In 1599, Elizabeth commanded master organ builder Dallam to construct and deliver to the Grand Signieur , as a present intended to garner trade and political advantages for England, a fantastic mechanical organ. Dallam’s wonder stood 16 feet high and was topped by a silver holly bush filled with blackbirds and thrushes that sung and shook their wings. Dallam kept a diary during his visit to Turkey, which included a sneak look through a grate at the Grand Turk’s ...
