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.

Plain speaking is necessary in any discussion of religion, for if the freethinker attacks the religious dogmas with hesitation, the orthodox believer assumes that it is with regret that the freethinker would remove the crutch that supports the orthodox. And all religious beliefs are "crutches" hindering the free locomotive efforts of an advancing humanity. There are no problems related to human progress and happiness in this age which any theology can solve, and which the teachings of freethought cannot do better and without the aid of encumbrances.

The progress of astronomy from age to age has been far from uniform—rather by leaps and bounds: from the earliest epoch when man's planet earth was the center about which the stupendous cosmos wheeled, for whom it was created, and for whose edification it was maintained—down to the modern age whose discoveries have ascertained that even our stellar universe, the vast region of the solar domain, is but one of the thousands of island universes that tenant the inconceivable immensities of space...

He stated that this policy was then replaced by one of cautious, progressive revelation. Keyhoe further stated that Earth had been visited by extraterrestrials for two centuries, with the frequency of these visits increasing sharply after the first atomic weapon test in 1945...

It was the 34th century and all five of the Federation of Planets around Sol were buzzing with their usual activity when the Raiders appeared. They were indeed Raiders of Universes because they had ravaged many systems before reaching Earth and showed no signs of slowing down in the least. Their weapons were invincible, their greed merciless and their natures completely alien. Indeed 'they' were from another dimension entirely. Eating up entire solar systems and planets, they slowed down just a bit when intelligent life was found on Earth...

Written when the United States extended only to the Mississippi River, by one of the signers of the Declaration of Independence, this short work explores the physical, social, and mental effects of distilled liquors; the classes of people prone to intoxication by them; suggested drinks to use instead of them; and remedies for intoxication and for their habitual use. He takes a medical view of alcoholism, exploring the physical causes rather than blaming moral failure as the cause. Alcoholic drinks that are not distilled are viewed as wholesome drinks, and opium is suggested for pain as being without bad effects or addictive qualities.

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...

The tragedy triggers actions on his part that pit him one-on-one against the horrible vortices. Introducing "storm" Cloud as THE Vortex Blaster

“Doc” E.E. Smith pretty much invented the space opera genre, and Triplanetary is a good and well-known example. Physics, time, and politics never stand in the way of a plot that gallops ahead without letup. Having earned a PhD in chemical engineering, it’s understandable that the heroes of Smith’s story are all scientists. He didn’t want to be constrained by the limits of known science, however, so in his hands the electromagnetic spectrum becomes a raw material to be molded into ever-more amazing and lethal forms, and the speed of light is no bar to traveling through the interstellar void...
