Triplanetary was first serialized in Amazing Stories in 1934. After the Lensman series became popular, Smith took his Triplanetary story and turned it into the first of the Lensman series, using it as a prequel to give the back story for the protaganists in the Lensmen series. He added 6 new chapters, doubling it in size and it's really a different book from the serialized novel, being published 14 years after the first. It was put into Gutenberg just last year. The novel covers several episodes in an eons-long eugenics project of the super-intelligences of the Arisia...

Written in the first century b.C., On the Nature of Things (in Latin, "De Rerum Natura") is a poem in six books that aims at explaining the Epicurean philosophy to the Roman audience. Among digressions about the importance of philosophy in men's life and praises of Epicurus, Lucretius created a solid treatise on the atomic theory, the falseness of religion and many kinds of natural phenomena. With no harm to his philosophical scope, the author composed a didactic poem of epic flavor, of which the imagery and style are highly praised.

Gregg Haljan was aware that there was a certain danger in having the giant spaceship Planetara stop off at the moon to pick up Grantline’s special cargo of moon ore. For that rare metal — invaluable in keeping Earth’s technology running — was the target of many greedy eyes. But nevertheless he hadn’t figured on the special twist the clever Martian brigands would use. So when he found both the ship and himself suddenly in their hands, he knew that there was only one way in which he could hope to save that cargo and his own secret — that would be by turning space-pirate himself and paying the Brigands of the Moon back in their own interplanetary coin.

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...

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...

Beginning in 1920, this Amendment prohibited the sale and manufacture of alcoholic beverages in the United States, until it was repealed in 1933.

This famous Pohl story explores cybernetic robots and implanted personalities in a way that certainly expanded my way of looking at reality. Is that wall really real? or is it just kinda, sorta real? And who am I? The protagonist, Guy Burckhardt, wakes up screaming from a horrible dream of explosions, searing fire, choking gas and other terrible ways to die. But he wakes up so it must have been just a bad nightmare, right? To find out that piece of information you will need to listen to this inventive and scary story.

She's worth plenty—dead or alive—to more than one faction in this obscure battle. And she's beginning to have a chilling notion that the long-vanished Masters of the Old Galaxy were wise when they exiled the plasmoids to the most distant and isolated world they knew....

The experiments herewith reported were undertaken with the view of introducing certain improvements into the oil-drop method of determining e and N and thus obtaining a higher accuracy than had before been possible in the evaluation of these most fundamental constants.

Notes on Nursing was published in 1859 and is a fascinating view into the theories underpinning the early development of modern nursing and public health reform by "the Lady with the Lamp", Florence Nightingale. Emphasising common sense and thought for the patient's care in many more ways than just administering physician-prescribed medicines, this is still a very relevant book for those interested in health or caring for the sick and infirm today.Summary by Cori Samuel.

Clifford Simak deals with the implications of time travel in his own unique way in this story. What if a group of guys did it on their own, without any help from government or industry? On a shoestring,so to speak? Would anyone believe them? What would you do if you could go back 150,000 years to a time when mastodons and saber toothed tigers roamed North America? And what happens when they run out of money? All these questions are explored in the usual humorous, wry Simak way in this story.

The famous physicist Sir Isaac Newton lectured on optics from 1670 - 1672. He worked on the refraction of light into colored beams using prisms and discovered chromatic aberration. He also postulated the corpuscular form of light and an ether to transmit forces between the corpuscles. His "Opticks", first published 1704 contains his postulates about the topic. This is the fourth edition in English, from 1730, which Newton corrected from the third edition before his death.

The power of population is indefinitely greater than the power in the earth to produce subsistence for man. Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio. A slight acquaintance with numbers will show the immensity of the first power in comparison with the second (Malthus).

Geology is a science of such rapid growth that no apology is expected when from time to time a new text-book is added to those already in the field. The present work, however, is the outcome of the need of a text-book of very simple outline, in which causes and their consequences should be knit together as closely as possible,—a need long felt by the author in his teaching, and perhaps by other teachers also. The author has ventured, therefore, to depart from the common usage which subdivides...
