The War of the Worlds is a military science fiction novel by H. G. Wells. It first appeared in serialized form in 1897, published simultaneously in Pearson's Magazine in the UK and Cosmopolitan magazine in the US. The first appearance in book form was published by William Heinemann of London in 1898. It is the first-person narrative of the adventures of an unnamed protagonist and his brother in Surrey and London as Earth is invaded by Martians. Written between 1895 and 1897, it is one of the earliest stories that detail a conflict between mankind and an extraterrestrial race. The novel is one of the most commented-on works in the science fiction canon. The War of the Worlds has two parts, Book One: The Coming of the Martians and Book Two: The Earth under the Martians. The narrator, a philosophically-inclined author, struggles to return to his wife while seeing the Martians lay waste to southern England. Book One also imparts the experience of his brother, also unnamed, who describes events in the capital and escapes the Martians by boarding a ship near Tillingham, on the Essex coast. The plot has been related to invasion literature of the time. The novel has been variously interpreted as a commentary on evolutionary theory, British Imperialism, and generally Victorian superstitions, fears and prejudices. At the time of publication it was classified as a scientific romance, like his earlier novel The Time Machine. The War of the Worlds has been both popular (having never gone out of print) and influential, spawning half a dozen feature films, radio dramas, a record album, various comic book adaptations, a television series, and sequels or parallel stories by other authors. It has even influenced the work of scientists, notably Robert Hutchings Goddard. Plot SummaryYet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us.— H. G. Wells (1898), The War of the Worlds The Coming of the MartiansThe narrative opens in an astronomical observatory at Ottershaw where explosions are seen on the surface of the planet Mars, creating much interest in the scientific community. Later a "meteor" lands on Horsell Common, near the narrator's home in Woking, Surrey. He is among the first to discover that the object is an artificial cylinder that opens, disgorging Martians who are "big" and "greyish" with "oily brown skin," "the size, perhaps, of a bear," with "two large dark-coloured eyes," and a lipless "V-shaped mouth" surrounded by "Gorgon groups of tentacles." The narrator finds them "at once vital, intense, inhuman, crippled and monstrous." They briefly emerge, have difficulty in coping with the Earth's atmosphere, and rapidly retreat into the cylinder. A human deputation (which includes the astronomer Ogilvy) approaches the cylinder with a white flag, but the Martians incinerate them and others nearby with a heat-ray before beginning to assemble their machinery. Military forces arrive that night to surround the common, including Maxim guns. The population of Woking and the surrounding villages are reassured by the presence of the military. A tense day begins, with much anticipation of military action by the narrator.

This book is called The White Spark as the white spark or vacuum cell in Nature IS THE RIGHT HAND OF GOD—it is a ubiquitous principle of the universe and is the cause and parent of electricity, combustion, radium, snow-flakes, flowers, trees, leaves, crystallization, wireless telegraphy, animal forms and EVEN LIFE ITSELF. This book is the key to every department of human endeavor, as it enunciates the basic principle and THE PRIME MOVER of the universe.?It tells the road to health, the cause and cure of disease, the truth about the germ humbug and drug treatments, serums and antitoxins. It shows why luminosity is produced on the flesh of various organisms, why a slice of pollock when first iced, then heated to 100 degrees and then thrust into a temperature of 50 degrees becomes luminous. It shows the farmer that he can become a magician of agriculture—tells that the nitrogen of the air is only a dust of quartz rocks, like the invisible moisture of the air is "a dust of water"—that the nodules on the roots of the clover and legumes do not abstract nitrogen from the air, for if they did nature would have placed these bacteriological growths on the vine and not the root, the scientists have the cart before the horse in this case and the nodular cells form the proteids from sand or silica, this book tells how it is done. It tells what a trance is and how the soul can leave the body temporarily. How JESUS CHRIST is carrying out the biblical prophesy by TELEPATHY. Gives the truths about the ideal society, alcohol, drunkenness, causes of crime, longevity and law.

Universul a nceput cu un Bang i s-a terminat cu un srut, ca toate marile iubiri“Ana Mnescu este o scriitoare tulburtor de generoas: ea nu mprtete cu cititorii doar ceea ce este la suprafa, explicit, nedureros, blnd; i plac subteranele, ascunziurile, visele uitate, ameninrile mute, teama fiinei de ea nsi, ntunericul care are nevoie doar de o scnteie pentru a se preschimba n lumin orbitoare. i ni le ofer pe toate, cu sinceritate i o delicatee care nu se mai regsete n nicio alt carte pe care ai putea-o citi vreodat. Quasarul poate construi o lume i o poate exploda ntr-o btaie de aripi. Pentru c totul i nimicul nseamn altceva numai dup ce au fost atinse de iubire. Ana scrie despre acele clipe n care eti cel mai adevrat tu care a existat vreodat. i eti cel mai mult tu cnd eti prins n iubire, ca ntr-o capcan de soare.“ (Cristina Nemerovschi)
