Lewis Carroll (1832-1896) is famous for Alice’s Adventures in Wonderland. It is less widely known that he worked as a lecturer for mathematics at Christ Church college, Oxford for 27 years. A tangled tale merges his two talents as storyteller and mathematician. It consists of ten short humorous stories which present one or more mathematical problems. The ten knots as they are called, were first published in The Monthly Packet magazine between April 1880 and March 1885, where readers were invited to solve the problems, and the solution was discussed in a later issue.

A light journey through the history of chemistry, from its start in the obscure mysteries of alchemy to what was, for the author, the cutting edge of the development of modern atomic theory … and whose developing blind ends we can now see with the advantage of hind sight.

Every status-quo-caste society in history has left open two roads to rise above your caste: The Priest and The Warrior. But in a society of TV and tranquilizers--the Warrior acquires a strange new meaning... (Introduction from the Gutenberg text)

Ronny Bronston has dreamed all his life of getting a United Planets job that would take him off-world. He finally gets the opportunity when he is given a provisional assignment with Bureau of Investigation, Section G. But will he be able to complete his assignment and find the elusive Tommy Paine?

The Kama Sutra, or Aphorisms on Love, has survived at least 1400 years as a dominant text on sexual relations between men and women. Vatsyayana claimed to have written the Kama Sutra while a religious student, “in contemplation of the Deity” - but references to older works, shrewd disputations by Vatsyayana of those authors' recommendations, and careful cataloging of practices in various of the Indian states indicate much more emphasis on kama, or sensual gratification. Part of the book discusses the 64 arts of love employed by masters of coitus...

On Architecture is a treatise on architecture written by the Roman architect Vitruvius and dedicated to his patron, the emperor Caesar Augustus as a guide for building projects. The work is one of the most important sources of modern knowledge of Roman building methods as well as the planning and design of structures, both large (aqueducts, buildings, baths, harbours) and small (machines, measuring devices, instruments). He is also the prime source of the famous story of Archimedes and his bath-time discovery.

Teenagers Peggy Prescott and her brother Roy share a love of aviation that they inherited from their late father. Mr. Prescott had always dreamed of building an aeroplane that would be free of the defects of planes already invented. Peggy and Roy manage to build a plane starting with the framework their father had begun. Peggy christens it ‘The Golden Buttefly’ and she and Roy are determined to enter it in a young aviator’s contest for a prize of $5000.

Marie Curie, born in Warsaw in 1867, was a French physicist and chemist famous for her work on radioactivity. She was a pioneer in the field of radioactivity and the first person honored with two Nobel Prizes - in physics (1903) and chemistry (1911). The risks of working with strongly radioactive materials were not known at that time, and she eventually died in 1934 from an illness likely caused by radiation poisoning.Radioactive Substances is the thesis of Marie Curie, presented to the Faculté de Sciences de Paris in 1903, and subsequently published in "Chemical News" vol 88, 1903...

In the book, the Lhari help the humans to travel faster than light and go to the far corners of different galaxies but are unwilling to give their secrets to them...

At one time Race Cargill had been the best Terran Intelligence agent on the complex and mysterious planet of Wolf. He had repeatedly imperiled his life amongst the half-human and non-human creatures of the sullen world. And he had repeatedly accomplished the fantastic missions until his name was emblazoned with glory. But that had all seemingly ended. For six long years he’d sat behind a boring desk inside the fenced-in Terran Headquarters, cut off there ever since he and a rival had scarred and ripped each other in blood-feud...

“Mark Phillips” is, or are, two writers: Randall Garrett and Laurence M. Janifer. Their joint pen-name, derived from their middle names (Philip and Mark), was coined soon after their original meeting, at a science-fiction convention. Both men were drunk at the time, which explains a good deal, and only one has ever sobered up. A matter for constant contention between the collaborators is which one. Originally published as That Sweet Little Old Lady, Brain Twister follows the adventures of FBI agent Kenneth J...

Mary Everest Boole (1832-1916) was born Mary Everest in England and spent her early years in France. She married mathematician George Boole. She was the author of several works on teaching and teaching mathematics in particular. This short book, Philosophy and Fun of Algebra, is meant to be read by children and introduces algebra and logic. She uses the word “algebra” broadly, defining it as a “method of solving problems by honest confession of one’s ignorance”. Using this definition, Boole introduces, in a conversational manner, the concepts of logic and algebra, illustrating these concepts with stories and anecdotes, often from biblical sources...

Mary Pengilly was taken to a Lunatic Asylum by her sons where she kept a diary, which this book is taken from. Mary records the harsh conditions and treatments received at the hands of the nurses during her stay. Once Mary is released she takes it upon herself to make the authorities aware of the situation at the Provincial Lunatic Asylum.

Regarded as the one of the earliest examples of feminist philosophy, A Vindication of the Rights of Woman is written as a direct response to Charles Maurice de Talleyrand-Périgord, a French politician who delivered a report to the French National Assembly suggesting that women should only receive domestic education and additionally encourages women to stay clear of political affairs. In her treatise, Wollstonecraft avidly criticizes this inadequate perception of women as an inferior sex and attacks social inequality, while also arguing for women’s rights in the hope of redefining their position both in society and in marriage...

A precursor to gothic literature and science fiction genres, Frankenstein is a novel fuming with imagination as it depicts a well known horror story. Shelly’s gothic fiction is written in epistolary form as a means of correspondence between the failed writer Robert Walton and his sister, while he is away on a dangerous expedition in search of fame. Some major themes explored in the gothic classic are the fallibility of ambition and knowledge, revenge, prejudice, isolation, and the imperfections of society...

The Last Man is an early post-apocalyptic science fiction novel by Mary Shelley, which was first published in 1826. The book tells of a future world that has been ravaged by a plague.

Save the Girls is an 1880 American anti-white-slavery book by reformed gambler Mason Long. In it, the author crusades against the social evil of prostitution by presenting a series of pathetic portraits of young women from various social classes who are brought low by such temptations of city life as the theater, the racecourse, and street flirtations. Included are vignettes of vice like "The Evils of Dancing - Sad Results of a Public Ball," in which innocent Marie, out for a good time, falls prey to the type of 'sporting men' who prowl such events in search of a partner for more than just The Glide or the Boston Dip.

Buzz, buzz, buzz. A fascinating and beautifully written explanation of the life of the honey bee. Is the queen the master of the hive or just a hard working servant? What is the purpose of the drones? Why do bees make honey? Do bees ever sleep? Why do bees swarm? Maeterlinck, who won the Noble Prize for Literature, wrote a more scholarly work called The Life of the Bee but then rewrote it in simpler terms so that children could appreciate what goes in a hive. The book describes in simple language the inner workings of a hive from its beginning with a swarm to the fully functional hive with thousands of workers, drones and a queen busily building, repairing and gathering.

The Chemical History of a Candle is a series of 6 lectures on chemistry presented to a juvenile audience in 1848. Taught by Michael Faraday - a chemist and physist, and regarded as the best experimentalist in the history of science - it is probably the most famous of the Christmas Lectures of the Royal Society. Taking the everyday burning of a candle as a starting point, Faraday spans the arc from combustion and its products, via the components of water and air (oxygen, hydrogen, nitrogen, carbon), back to the type of combustion that happens in the human body when we breathe...

This story starts with space ships scouring the universe in an interplanetary game of tag. The humans know there are “Aliens” out there. But so do the Aliens. As each tries desperately to make the phenomenal discovery, they secretly hope that the other will not turn out to be the enemy. Humans call them “Plumies” because of the feathery plumes they inscribe on silicon-bronze tablets and cairns they have left behind on their intergalactic travels over the last thousand years. The search goes on, till one day somewhere in outer space, a Plumie ship collides with the one manned by humans...

An unidentified space ship lands in a Colorado lake. Equipped with a paralyzing ray weapon, the creatures begin taking human prisoners. A loan land surveyor and a journalist are trapped inside the Army cordon, which is helpless against the mysterious enemy. Can they stop the aliens before it is too late?

Joe Kenmore heard the airlock close with a sickening wheeze and then a clank. In desperation he turned toward Haney. “My God, we’ve been locked out!” Through the transparent domes of their space helmets, Joe could see a look of horror and disbelief pass across Haney’s face. But it was true! Joe and his crew were locked out of the Space Platform. Four thousand miles below circled the Earth. Under Joe’s feet rested the solid steel hull of his home in outer space. But without tools there was no hope of getting back inside. Joe looked at his oxygen meter. It registered thirty minutes to live.

Bron is the offspring of infamous space pirates but instead of following in the family footsteps he decides to become an electronic engineer. Unfortunately, every time he tries to get out, something pulls him back in. This is a tongue-in-cheek space adventure along the lines of the Stainless Steel Rat by Harry Harrison. It was originally published in the FEB-APR issues of Astounding Science Fiction in 1959.

Calhoun is an Interstellar Medical Serviceman, and he's needed on Dara. Trouble is: Dara is forbidden. Taboo. And breaking quarantine will make Calhoun a presumed plague-carrier and subject to being shot on sight by anyone from Weald. But hey! If he did the smart thing, we wouldn't have a story!But why are men from Dara shooting at him?

Bors felt as if he'd been hit over the head. This was ridiculous! He'd planned and carried out the destruction of that warship because the information of its existence and location was verified by a magnetometer.But, if he'd known how the information had been obtained--if he'd known it had been guessed at by a discharged spaceport employee, and a paranoid personality, and a man who used a hazel twig or something similar--if he'd known that, he'd never have dreamed of accepting it. He'd have dismissed it flatly!

Dr. Calhoun and his pet tormal Murgatroyd work for the Interstellar Medical Service making routine public health inspections on far-flung colonial planets. When they reach Tallien Three they are greeted with a rocket attack by the Paras, a mutated form of human rapidly replacing the “normals”. The normals think it’s a pandemic of demonic possession but Calhoun has his doubts. If he can keep from turning into a Para, or being assassinated by them he just might figure this thing out. – The Hate Disease was first published in the August 1963 edition of Analog Science Fact and Fiction magazine.

Jed Cochrane is about to take off on man's first interstellar voyage. His mission: Make sure it's good television! (Introduction by Mark Nelson)

They were broadcasts from nowhere--sinister emanations flooding in from space--smashing any receiver that picked them up. What defense could Earth devise against science such as this? In the far future of 1972, on a secret military installation, Staff Sergeant Bellews is an expert on the latest scientific discovery: a way for ordinary machines like vacuums and lawnmowers to gather experience in their jobs, becoming error free over time. Then the strange broadcasts began to blow up transmitters everywhere. Were they from space? Enemies? the future? He didn't care until they started messin' with his machines. Then he took it personally. (summary from the first chapter and Phil Chenevert)

Big Jake Connors is taking over his town through violence, inimidation and bribery but Detective Sergeant Fitzgerald can only grind his teeth in frustration. The gangsters seem to have everything going their way until the day that a little dry cleaning establishment declines their offer of 'protection' and strange things start to happen. Murray Leinster gives us another wonderful product of 'what if' from his limitless imagination to enjoy in this gem of a story. Listen and smile.

When the blue plague appeared on the planet of Dara, fear struck nearby worlds. The fear led to a hate that threatened the lives of millions and endangered the Galactic peace. (Excerpt from the text.)

SPACE PLATFORM tells the exciting story of a young man helping to build this first station. With scientific accuracy and imagination Murray Leinster, one of the world's top science-fiction writers, describes the building and launching of the platform. Here is a fast-paced story of sabotage and murder directed against a project more secret and valuable than the atom bomb!

A cross between guidebook and social commentary, The Spinster Book gives clever and humorous insights on topics such as courting, handling men and women, love letters, marriage and spinsterhood.

" Believing that the woman's claim to a common humanity is not an unreasonable one, and that the successful issue of such claim rests primarily upon the sense of fair play which people have or have not according to how they were born, and Therefore to men and women everywhere who love a fair deal, and are willing to give it to everyone, even women, this book is respectfully dedicated by the author."

Machiavelli has created a ruthless guide on how to rule the country in his volume "The Prince". The book is dedicated to Lorenzo De Medici, the ruler of Florence. The author explains in simple language about the nature of great men and the characters of the government. The first chapter gives an outline of the book discussing various styles of ruling as a prince, character traits that a ruler should have and the political situation of Italy in the 16th century. The book is composed of 26 chapters which fall into four major sections...

The Interesting Narrative of the Life of Olaudah Equiano, written in 1789, is the autobiography of Olaudah Equiano. It discusses his time spent in slavery, serving primarily on galleys, documents his attempts at becoming an independent man through his study of the Bible, and his eventual success in gaining his own freedom and in business thereafter. The book contains an interesting discussion of slavery in West Africa and illustrates how the experience differs from the dehumanising slavery of the Americas...

This book takes its origin in a course of lectures on the history and progress of Astronomy arranged for Sir Oliver Lodge in the year 1887. The first part of this book is devoted to the biographies and discoveries of well known astronomers like Copernicus, Brahe, Kepler, Galileo and Newton. In the second part, the biographies take a back seat, while scientific discoveries are discussed more extensively, like the discovery of Asteroids and Neptune, a treatise on the tides and others.

When the pace of railroad construction slackened in 1914, Canada had achieved a remarkable position in the railway world. Only five other countries—the United States, Russia, Germany, India, and, by a small margin, France—possessed a greater mileage; and, relatively to population, none came anywhere near her. This is the story of how Canada became a country stitched together by rail.

Yoga sutras by Patanjali is a seminal work in yoga, this book is more about control of mind and the true goal of yoga. The sutras are extremely brief, and the translation in neat English makes it very easy for people to understand the ancient Sanskrit text. It starts with the birth and growth of spiritual man through the control of mind. In all, this is a "all in one" book for yoga philosophy written by the master himself.

This is a textbook on the science of blood and bloodwork by (1908) Nobel Prize winner, Dr. Paul Ehrlich. Should appeal to hematologists, phlebotomists, and just plain folks interested in how our bodies work.

Mutual Aid: A Factor of Evolution is a book by Peter Kropotkin on the subject of mutual aid, written while he was living in exile in England. It was first published by William Heinemann in London in October 1902. The individual chapters had originally been published in 1890-96 as a series of essays in the British monthly literary magazine, Nineteenth Century. Written partly in response to Social Darwinism and in particular to Thomas H. Huxley’s Nineteenth Century essay, The Struggle for Existence, Kropotkin’s book drew on his experiences in scientific expeditions in Siberia to illustrate the phenomenon of cooperation...

In this work, Kropotkin points out what he considers to be the fallacies of the economic systems of feudalism and capitalism, and how he believes they create poverty and scarcity while promoting privilege. He goes on to propose a more decentralised economic system based on mutual aid and voluntary cooperation, asserting that the tendencies for this kind of organisation already exist, both in evolution and in human society.

Two early science fiction stories by the wonderful craftsman, Philip K. Dick. In the Crystal Crypt, taken from the 1954 Planet Stories, the war between Mars and Terra is about to erupt and earth has only merchants and salesmen to fight; can they carry out their mission? Beyond the Door is a story that asks and answers the question: what lives beyond the door? And is it dangerous?

The terrible destruction of total nuclear war between the Western and Eastern Blocks has succeeded in sterilizing the surface of the earth. No living creature can now exist there and all humans on both sides, have fled to the hives built miles below the surface where they constantly work to produce the war materials necessary to carry on the battle. For 8 years now, the actual fighting between these super powers has been conducted by robots known as Ledeys since only they can sustain the terrible levels of radiation caused by the constant bombardment...

Two stories in the inimitable Philip Dick style. What is a Wub? A 400 pound slovenly, fat, ungainly, drooling animal that looks like a cross between a walrus and an enormous hog? Well, yes that is pretty much what he looks like and for 50 cents, a good bargain no matter how he tastes. The hungry spaceship crew expect to find out. Of course the Wub may not entirely agree but it doesn't have much to say about it. The second story, The Skull, is a skilful mesh of time travel, unscrupulous governments, prisoners, and religion. With an assassin thrown in for good measure. Enjoy!

The sequel to Plague Ship, Voodoo Planet finds the Solar Queen banned from trade and starting her supposed quiet two-year stint as an interstellar mail carrier. But instead her crew accepts a visit to the safari planet of Khatka, where they find themselves caught in a battle between the forces of reason and the powers of Khatka’s mind-controlling wizard.

Νόμοι (Laws) is Plato's final dialogue written after his attempt to advise the tyrant Dionysius II of Syracuse. The dialogue takes place between: an Athenian Stranger (Socrates? A god in human form?); the quiet Lacedaemonian Megillus; and the Cretan Cleinias. The Stranger asks whether humans live to be more effective at waging war or if there is something more important a legislator should seek to achieve. During their pilgrimage Cleinias discloses his role in the establishment of a new colony...

“Security”, tells the story of a compartmentalized government physicist ordered by secret police to complete experiments aimed at developing a new weapon. He is brought to a hidden space station and put in charge of the project but there are many questions. In a world of spies watching spies it’s sometimes hard to know what’s patriotic. -- Poul Anderson was a Golden Age Science Fiction and Fantasy author. “Security” first appeared in the magazine “Space Science Fiction” in February of 1953

Presented in the form of lessons, R. Cadwallader Smith vividly portrays life in the ocean. Learn about the common and not so common that swim about in the deep, how they hunt for food and hide from enemies, visit a nursery and find out about the babies that live there, or take a stroll in an underwater garden.

Set in a future in which humanity’s dream of total equality is fully realized and poverty in terms of material wealth has been eliminated, humanity has straight-jacketed itself into the only social system which could make this possible. Class differentiation is entirely horizontal rather than vertical and no matter what one’s chosen field, all advancement is based solely on seniority rather than ability. What is an intelligent and ambitious man to do when enslaved by a culture that forbids him from utilizing his God-given talents? If he’s a military officer in time of war, he might just decide to switch sides...

Can a spaceship go crazy? Well, yes it can if it has a brain. And the new MG (magnetogravitic drive) experimental robot space ship does indeed have a 'brain'. Completely bewildered as to why the first six models of their supposedly perfect new ship model, the MG-YR, nicknamed the McGuire, have gone totally bonkers after activation and before they could ever be used, the company has called in the services of Daniel Oak. They suspect sabotage of course. Daniel Oak is the hard boiled private investigator with nerves of steel and a mind of the same substance...

When a super-robot named Snookums discovers how to build his own superbombs, it becomes obvious that Earth is by no means the safest place for him to be. And so Dr. Fitzhugh, his designer, and Leda Crannon, a child psychologist acting as Snookums’ nursemaid, agree to set up Operation Brainchild, a plan to transport the robot to a far distant planet. But the space ship becomes the scene of some frightening events--the medical officer is murdered, and Snookums appears to be the culprit…

Randall Garrett had this story first published in Astounding Science Fiction September and October of 1959. His twisted sense of humor and gift for the bizarre situation with believable characters shines here. In the not too distant future, Ken Malone, young but promising FBI agent , is given the most important and difficult assignment of his career: find a spy who is stealing information from the Ultra Top Absolute Secret project to develop a non-rocket space ship at Yucca Flats Labs in Nevada. But this is not a normal spy, this spy laughs at the FBI and all attempts to find him or her because they use an unknown new method to steal the information directly from the minds of the scientists.

An alien crash lands on Earth, and for ten years terrorizes the planet, hiding, periodically killing and eating people and stealing materials for some unknown purpose. The only hope is Bart Stanton, a medically-engineered superman, designed for the sole purpose of confronting the “Nipe”.

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. (From the Gutenberg e-text)

Lee Anthony finds himself and two of his friends kidnapped and taken on a strange voyage.

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. )

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...
