An account given of the lives of five great naturalists (Hippocrates, Aristotle, Galen, Vesalius and Harvey) will not be found devoid of interest. The work of each one of them marked a definite advance in the science of Biology. There is often among students of anatomy and physiology a tendency to imagine that the facts with which they are now being made familiar have all been established by recent observation and experiment. But even the slight knowledge of the history of Biology, which may be obtained from a perusal of this little book, will show that, so far from such being the case, this branch of science is of venerable antiquity...

The first half of this book describes the devastating earthquake that hit San Francisco in 1906, and the subsequent destruction caused by fire. Various eyewitnesses and victims give their account on the tragedy. In the second half, a number of different other earthquakes and volcanic eruptions are retold, like the eruption of the Vesuvius that destroyed Pompeij or the explosion of the Krakatoa, together with scientific explanations for the causes of earthquakes and the eruption of volcanos.

"While many scientific men now understand our place in the universe, we electrons are anxious that every person should know the very important part which we play in the workaday world. It was for this reason that my fellow-electrons urged me to write my own biography. I am pleased to say that my relationship with the scribe who has put down my story in the following pages has been of the most friendly description. I have allowed him to place what he calls "The Scribe's Note" at the beginning of each chapter, but it will be understood clearly that these are merely convenient embellishments, and that I am responsible for the story of my own experiences." (Introduction adapted from the text)

Chet Ballard answers the pinpoint of light that from the craggy desolation of the moon stabs out man's old call for help.

Clarence Darrow was an American lawyer. He remains notable for his wit and agnosticism, which marked him as one of the most famous American lawyers and civil libertarians.In this book, Darrow expands on his lifelong contention that psychological, physical, and environmental influences—not a conscious choice between right and wrong—control human behavior. To my ears (the reader's), the author has a rather simplistic behaviourist view of human behaviour, but he argues his position with wonderful clarity...

In a future time, the solar system is powered by one energy source, controlled by one huge organisation, which has plans to use this control to dominate the planets. Unknown to them, a couple of maverick scientists accidentally develop a completely new form of energy supply and threaten the corporation's monopoly. Naturally, the corporation can't allow this to happen... A stunning story about the manipulation of pure energy, climaxing in interstellar conflict.

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.

Larry Woolford is a government agent, tasked with investigating subversive activity.

Can he stop their fiendish plan, and keep America safe for shallow judgements based on status symbols? Status Quo was nominated for the 1962 Hugo Award for short fiction.

“The martyrs of Science” gives a brief biography of Galileo, Brahe and Kepler. These three men played a pivotal role in the scientific revolution during the early modern period. This book throws light upon their lives, their scientific achievements, adversities which they faced for their work and how they transformed the lives of the future generations forever. It also provides evidence which establishes that the work carried out by them are original irrespective of the claims by other men who tried in vain to rob them of their honor. The author highlights some of their fallacies which hindered their progress.

A Voyage to Arcturus is a novel by Scottish writer David Lindsay, first published in 1920.

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.
