Book cover Fire People

In effect Professor Newland declared that the curious astronomical phenomena of the previous November--the new "stars" observed, the two meteors that had fallen with their red and green light-fire--were all evidence of the existence of intelligent life on the planet Mercury. (An excerpt from chapter 1. )

Book cover Wandl the Invader

There were nine major planets in the Solar System and it was within their boundaries that man first set up interplanetary commerce and began trading with the ancient Martian civilization. And then they discovered a tenth planet--a maverick! This tenth world, if it had an orbit, had a strange one, for it was heading inwards from interstellar space, heading close to the Earth-Mars spaceways, upsetting astronautic calculations and raising turmoil on the two inhabited worlds. But even so none suspected then just how much trouble this new world would make...

Book cover The White Invaders
Book cover Tarrano the Conqueror

In "Tarrano the Conqueror" is presented a tale of the year 2430 A.D.--a time somewhat farther beyond our present-day era than we are beyond Columbus' discovery of America. My desire has been to create for you the impression that you have suddenly been plunged forward into that time--to give you the feeling Columbus might have had could he have read a novel of our present-day life. To this end I have conceived myself a writer of that future time, addressing his contemporary public. You are to imagine...

The People's Common Sense Medical Adviser by Ray Vaughn Pierce The People's Common Sense Medical Adviser

The People's Common Sense Medical Adviser In Plain English, Or, Medicine Simplified. By R.V. Pierce, M.D. INTRODUCTORY WORDS. Health and disease are physical conditions upon which pleasure and pain, success and failure, depend. Every individual gain increases public gain. Upon the health of its people is based the prosperity of a nation; by it every value is increased, every joy enhanced. Life is incomplete without the enjoyment of healthy organs and faculties, for these give rise to the delightful sensations of existence...

The Planet Strappers by Raymond Z. Gallun The Planet Strappers

The Planet Strappers started out as The Bunch, a group of student-astronauts in the back room of a store in Jarviston, Minnesota. They wanted off Earth, and they begged, borrowed and built what they needed to make it. They got what they wanted--a start on the road to the stars--but no one brought up on Earth could have imagined what was waiting for them Out There!

Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences by René Descartes Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences

The Discourse on Method is best known as the source of the famous quotation “cogito ergo sum”, “I think, therefore I am.” …. It is a method which gives a solid platform from which all modern natural sciences could evolve. With this work, the idea of skepticism was revived from the ancients such as Sextus Empiricus and modified to account for a truth that Descartes found to be incontrovertible. Descartes started his line of reasoning by doubting everything, so as to assess the world from a fresh perspective, clear of any preconceived notions.

After London, or Wild England by Richard Jefferies After London, or Wild England

First published in 1885, After London, or Wild England is considered to be one of the earliest instances of post-apocalyptic fiction, describing the effects of an unspecified catastrophe that dramatically changes the face of England and its population. Divided into two parts, the first depicts the fall of civilization, as society reverts to its more primitive roots, while the second part is set years after the apocalyptic event and examines the evident changes in both natural scenery and social structure...
