A Periscoping Pillbox


A Pickett-Hamilton fort is a type of hardened field fortification built in Britain during the invasion crisis of 1940–1941.  The Pickett-Hamilton fort was designed to be lowered into the ground while it was not in use, as such it would be inconspicuous and would not interfere with the passage of taxiing aircraft or other vehicles. The fort could be raised to about 2 feet 6 inches (0.76 m) above ground level where it would be a physical impediment to aircraft [including soldiers parachuting into an airfield] and vehicles and from where a small crew could fire with rifles or light machine guns.

Development

The open spaces of airfields were very vulnerable to attack by airborne troops and it was felt that it was particularly important to defend them effectively. However, conventional defences such as pillboxes and trenches could not be installed without danger to friendly aircraft. At this time a number of private companies contacted the government with their own design ideas.

The Pickett-Hamilton fort was designed by Francis Norman Pickett and Donald St Aubyn Hamilton. Pickett (1887–1957) was an engineer. He graduated from London University in 1907, and from 1918 to 1931 he was Proprietor of the firm of F. N. Pickett et Fils, engaged on the demolition of ammunition. This business encountered many difficulties but Pickett made a great deal of money before the company eventually failed.  Pickett spent much of the early '20s involved in motor racing. He subsequently became Managing Director of Kaycee, Ltd., in 1931–35, of Consolidated Rubber Manufacturers, Ltd., in 1935–38, and of Ocean Salts (Products), Ltd., in 1938. Hamilton (1907–1956) was an architect based in London. Later, as part of Donald Hamilton, Wakeford & Partners, he designed many buildings in London and southern England.

A friend of Norman Pickett, racing driver Donald Campbell, allowed his workshops to be used to build the prototypes. In early 1940, Campbell attended the operational trials of the prototype at RAF Andover.

Winston Churchill wrote to General Ismay on 12 July 1940 saying: "I saw these pillboxes for the first time when I visited Langley last week. This appears to afford an admirable means of anti-parachute defence and it should surely be widely adopted. Let me have a plan." This pillbox was adopted by the Air Ministry and became known as the Pickett-Hamilton fort

Design

The most common version of the Pickett-Hamilton fort consists of two cylinders of pre-cast concrete each with one end closed. The slightly smaller of the two cylinders slides into the larger and they are kept apart by small guard rollers on the moving part that engaged with grooves. The structure is buried so that the overhanging top of the smaller cylinder lies flush with the ground. Closed in this position the pillbox is inconspicuous and allows aircraft and other vehicles to safely drive straight over it.

The interior is accessed via a small hatch and rungs built into the structure. To bring it into action a lifting mechanism was used to raise the inner cylinder by about 2 feet 6 inches (0.76 m) thereby revealing three embrasures. A crew of two men could then operate the fort as a pillbox.

Initially, the lifting mechanism consisted of a standard 8-ton aeroplane jack that took three minutes to raise the fort. This was soon replaced with a pneumatic ram that was based on a system originally intended for agricultural use. The pneumatic system operated with compressed air stored in cylinders: this allowed the fort to be raised and lowered quickly when speed was essential. A hand pump was also provided to raise the fort for daily maintenance or as a backup method.

An alternative design used counterbalance weights to raise the fort. This allowed the fort to be raised by the physical strength of the garrison. This design had two access hatches and, with a slightly larger underground chamber and the elimination of the central pneumatic ram the fort could have a crew of four men. Under consideration in late 1940, this alternative design was not used in significant numbers and only about a dozen were installed.

The cost of construction was about £240 (equivalent to £11,800 in 2017

Coming: Vaccine for Zika Virus

Discovery of a Zika Antibody
Offers Hope for a Vaccine

Rockefeller University, May 4, 2017 -- A research team based at The Rockefeller University has identified a potent new weapon against the Zika virus in the blood of people who have been infected by it. This discovery could lead to new ways of fighting the disease, including a vaccine.

In blood samples taken from subjects in Mexico and Brazil, the scientists found antibodies—proteins produced by the immune system—that block the virus from initiating an infection. The antibodies appeared to have been initially generated in response to an earlier infection by a related virus that causes dengue.

“In the near future, these antibodies could be very useful. One could envision, for example, administering them to safely prevent Zika among pregnant women or others at risk of contracting the disease,” says Davide F. Robbiani, a research associate professor in Michel C. Nussenzweig’s lab. He and Leonia Bozzacco, a research affiliate in Charles M. Rice’s lab, led the study, which appeared in Cell on May 4.

The team’s detailed examination of the interaction between this antibody and the virus also revealed a new potential strategy for developing a vaccine.

A precise target

A mosquito-borne virus, Zika usually causes mild symptoms in those who contract it. However, dramatic effects can appear in the next generation. Babies born to women infected during pregnancy are at risk of devastating neurodevelopmental abnormalities. The only way to prevent Zika is to avoid mosquito bites; there are currently no vaccines or other medical measures.

An infection begins when the virus, traveling in a spherical particle studded with the viral envelope protein, latches onto a host cell and forces its way in. Faced with a viral threat, the human immune system generates antibodies that recognize the virus and stop it from invading cells. The team set out to find antibodies tuned to a particular target: a part of Zika’s envelope protein, which the virus needs to launch an attack.

Five out of six

Through collaborators working in Pau da Lima, Brazil, and Santa Maria Mixtequilla, Mexico, they obtained blood samples from more than 400 people, collected shortly after Zika was circulating.

Individual responses to the same pathogen can vary greatly. Yet a deeper analysis of samples from six of the volunteers with the most promising antibodies revealed a surprise: Five of them contained the same species of nearly identical antibodies. This similarity suggested these molecules were particularly good at fighting the virus.

When the team examined these closely related antibodies’ performance against Zika, one, obtained from a Mexican volunteer’s blood, stood out. When this antibody, called Z004, was given to mice rendered vulnerable to Zika, it protected them from developing serious infections.

A shared ridge

To get a closer look at the interaction between the antibody and a fragment of the virus’ envelope protein, scientists in Pamela J. Bjorkman’s lab at Caltech determined the molecular structure formed as the two units interacted. Their detailed maps revealed how the antibody pinches a ridge on the virus when it binds to it.

While some efforts to develop a vaccine use all or most of the virus to stimulate the immune system, the researchers believe it could be safer to employ only a tiny fragment containing this ridge.

Zika isn’t the only virus to sport the ridge, as it is also present in envelopes of other viruses in the same family. The dengue 1 virus, a close relative of Zika and one of four types of dengue, has a ridge that is remarkably similar to Zika’s. When pitted against dengue 1, Z004 neutralized this virus as well.

A look back at samples from the Brazilians, collected six months before Zika arrived by a team led by Albert Ko of Yale University, revealed evidence of prior dengue 1 infections in some—and a potential explanation as to why certain people’s immune systems fared better against Zika.

“Even before Zika, their blood samples likely had antibodies that could interact with this same spot on the envelope protein,” says Margaret R. MacDonald, a research associate professor in Rice’s lab. “It appears that, much like a vaccine, dengue 1 can prime the immune system to respond to Zika.”

Flown: Chinese Commercial AIrliner


The Comac C919 is a narrow-body twinjet airliner developed by Comac. The program was launched in 2008 and production of the prototype began in December 2011. It rolled out on 2 November 2015 and first flew on 5 May 2017, for a planned introduction in 2020. Mainly constructed in classical aluminum, it is powered by CFM International LEAP turbofans and should carry 156 to 168 passengers up to 3,000 nmi (5,600 km). It will compete with the similarly made and powered Boeing 737 MAX and Airbus A320neo. After the last November 2016 order, 570 aircraft are booked from 23 customers, mainly Chinese leasing companies or airlines.
                                      Comac C919 model from 2010                    
      
Development

The 2008 program launch initially targeted a 2014 maiden flight. Comac applied for a type certificate for the aircraft from the Civil Aviation Authority of China on 28 October 2010. The company intends to manufacture up to 2,300 aircraft of that type. In June 2011 COMAC and Irish low-cost airline Ryanair signed an agreement to co-operate on the development of the C919 In 2012 Airbus' chief strategist Marwan Lahoud was assuming that the aircraft would offer competition to Airbus by 2020.

On 24 November 2011, Comac announced the completion of the joint definition phase, marking the end of the preliminary design phase for the C919, with estimated completion of the detailed design phase in 2012. Production of the first C919 testing prototype began on 9 December 2011. The annual production was targeted at 150 planes by 2020.

Its announced development budget is 58 billion yuan ($9.5 billion) but the real cost is estimated 100% higher for well over $20 billion.  The flight testbed was expected to enter final assembly in 2014, and perform its first flight in 2015. Delivery was delayed again to 2018 by technology and supplier problems. At the November 2014 Zhuhai Airshow, the first flight was delayed to 2017. C919's advanced aerodynamics were engineered with the help of the Tianhe-2 supercomputer. Comac rolled out its first C919 aircraft off the assembly line in September 2015 with no engines installed.

On 2 November 2015, Comac rolled out its first C919 aircraft. High-speed taxi tests were completed in April 2017. Carrying a crew of five, its first flight took place on 5 May 2017. Comac plan a test program of 4,200 flight hours and introduction in 2020 with China Eastern Airlines.

Design

Dimensions of the C919 are very similar to the Airbus A320, possibly to allow for a common Unit Load Device to be used: its fuselage will be 3.96 meters (13 feet) wide, and 4.166 meters (13 feet, 8 inches) high for a 12.915 square meters (139 square feet) cross-section, its wingspan will be 33.6 meters (110 feet, 3 inches), 35.4 meters (116 feet, 3 inches) with winglets.

Payload will be 20.4 metric tons, it will cruise at Mach 0.785 (450 kn; 834 km/h) at a 12,100 meters (39,800 feet) ceiling and there will be two variants : the standard version with a 4,075 km (2,200 nmi) range, and a 5,555 km (2,999 nmi) extended-range version. At the 2010 Zhuhai Airshow, Comac planned to build a 168-seat (156-seat in two class) base passenger aircraft, as well as stretched and shrunk passenger versions, business jet and freighter models, and a type designated only as "special".

The center wing box, outer wing box, wing panels, flaps, and ailerons are planned to be built in Xi'an, China ; the center fuselage sections are planned to be built in Hongdu, China. The center wing box was originally intended to use of carbon fiber composites. It was changed later to an aluminum design to reduce program complications. The airframe will be made largely of aluminum alloy. Design and assembly of the aircraft is done in Shanghai.

The wing is supercritical, increasing aerodynamic efficiency by 20% and reducing drag by 8%. Aluminum-lithium alloys account for 8.8% of the structure and composite materials for 12%.

Pratt & Whitney offered its PW1000G geared turbofan. CFM International was ultimately selected to supply its LEAP-1C engine. AVIC Commercial Aircraft Engine Co is tasked to develop indigenous engines. The ACAE CJ-1000A was unveiled at the 2012 Zhuhai Airshow.

The engine's nacelle, thrust reverser and exhaust system will be provided by Nexcelle, with such features as an advanced inlet configuration, the extensive use of composites and acoustic treatment and an electrically operated thrust reverser. Michelin will supply Air X radial tires.

Market

As the 380 units order book in 2012 was worth US$26 billion, its average price was US$68.4 million. FlightGlobal's Ascend market values in 2013 were $49.2 million for the Airbus A320neo, 51% less than its $100.2 million list price and $51.4 million for the Boeing 737 MAX-8, 49% less than its $100.5 million list price. In June 2015 the China National Radio predicted a US$50 million price, cheaper than the B737 or A320 list prices.

The Chinese airlines that have placed orders for the C919 already have either the Boeing 737 or Airbus A320 in their fleets. In 2013, Chinese state-owned newspaper Global Times complained that an Aviation Week editorial about the bleak prospects for the aircraft "maliciously disparaged the future outlook for the C919." COMAC aims to take a fifth of the global narrowbody market and a third of the Chinese market by 2035.

Cheap HD Microscopes


Chip-based Nanoscopy: Microscopy in High Definition

April 17, 2017 -- Physicists at Bielefeld University and The Arctic University of Norway in Tromsø have developed a photonic chip that makes it possible to carry out superresolution light microscopy, also called ‘nanoscopy’, with convention al microscopes. In nanoscopy, the position of single fluorescent molecules can be determined with a precision of just a few nanometres, that is, to a millionth of a millimetre. This information can be used to produce images with a resolution of about 20 to 30 nanometres, and thereby ten times that of conventional light microscopy. Until now, this method has required the use of expensive special instruments. Bielefeld University and the University of Tromsø have filed a patent for this new ‘chip-based nanoscopy’ procedure. On the 24th of April 2017 the researchers will be publishing the accompanying study in the journal ‘Nature Photonics’.

Dr. Mark Schüttpelz from Bielefeld University and Dr. Balpreet Singh Ahluwalia (University of Tromsø) are the inventors of this photonic waveguide chip. Professor Dr. Thomas Huser and Robin Diekmann from Bielefeld University’s Biomolecular Photonics Group also worked on developing this new concept. The invention makes experiments much easier to perform: a probe is illuminated directly on a chip about the size of a specimen slide. A lens and a camera record the signal perpendicular to the chip. The measurement data obtained can be reconstructed as superresolved images with a markedly higher resolution than that obtained with conventional microscopy.

Whereas the images that can be obtained simultaneously with established nanoscopy techniques range from only parts of cells up to just a few cells, the use of photonic chips now makes it possible to visualise more than 50 cells in one superresolution image. ‘The invention of the new chip-based superresolution technique is a paradigm shift in microscopy, and it will now permit a much broader use of nanoscopy in science, research, and everyday applications,’ says Dr. Mark Schüttpelz.

Current nanoscopic techniques are extremely complex, expensive, and require intensively trained technicians. Up to now, these limitations have restricted the use of nanoscopy to only highly specialized institutes throughout the world and prevented its spread to standard laboratories in biology and medicine let alone to hospitals and analytical laboratories.

The invention of the ‘chip-based nanoscopy’ procedure by researchers at Bielefeld and Tromsø will take its place in the long history of developments in microscopy and nanoscopy:

  • In 1609, Galileo Galilei invented light microscopy.
  • In 1873, Ernst Abbe discovered the fundamental property that limits the resolution of an optical system for visible light to roughly 250 nanometres.
  • In recent years, several optical methods have been developed concurrently in order to overcome the diffraction   limit  of light. In 2014, the Nobel Prize for Chemistry was awarded for the development of a superresolution in the range of roughly 20 to 30 nanometres.

Gluten: Prolamins and Glutelins

Gluten is a composite of storage proteins termed prolamins and glutelins found in wheat and related grains, including barley, rye, oat, and all their species and hybrids (such as spelt, khorasan, emmer, einkorn, triticale, etc.). Gluten is appreciated for its viscoelastic properties. It gives elasticity to dough, helping it rise and keep its shape and often gives the final product a chewy texture.

Gluten is conjoined with starch in the endosperm of various grassrelated grains. Wheat prolamins are called gliadins, barley prolamins are hordeins, rye prolamins are secalins and oats prolamins are avenins, which are collectively named gluten. Oat avenin toxicity in people with gluten-related disorders depends on the oat cultivar consumed because the immunoreactivities of toxic prolamins are different among oat varieties. Also, many oat products are cross-contaminated with other gluten-containing cereals.

The fruit of most flowering plants have endosperms with stored protein to nourish embryonic plants during germination. True gluten is limited to the grains listed above. The stored proteins of maize and rice are sometimes called glutens, but their proteins differ from true gluten.

Preparation

Gluten is a protein complex that accounts for 75 to 85% of the total protein in bread wheat. Gluten is prepared from flour by kneading the flour under water, agglomerating the gluten into an elastic network, a dough, and then washing out the starch. Starch granules disperse in cold/low-temperature water, and the dispersed starch is sedimented and dried. If a saline solution is used instead of water, a purer protein is obtained, with certain harmless impurities departing to the solution with the starch. Where starch is the prime product, cold water is the favored solvent because the impurities depart from the gluten.

In home or restaurant cooking, a ball of wheat flour dough is kneaded under water until the starch disperses out. In industrial production, a slurry of wheat flour is kneaded vigorously by machinery until the gluten agglomerates into a mass. This mass is collected by centrifugation, then transported through several stages integrated in a continuous process. About 65% of the water in the wet gluten is removed by means of a screw press; the remainder is sprayed through an atomizer nozzle into a drying chamber, where it remains at an elevated temperature a short time to evaporate the water without denaturing the gluten. The process yields a flour-like powder with a 7% moisture content, which is air cooled and pneumatically transported to a receiving vessel. In the final step, the processed gluten is sifted and milled to produce a uniform product

Adverse Reactions

Gluten-related disorders is the umbrella term for all diseases triggered by gluten, which include celiac disease (CD), non-celiac gluten sensitivity (NCGS), wheat allergy, gluten ataxia, and dermatitis herpetiformis (DH). Currently, their incidence is increasing in most geographic areas of the world. It can be explained possibly by the growing westernization of diet, increasing use of wheat-based foods included in the Mediterranean diet, the progressive replacement of rice by wheat in many countries in Asia, the Middle East, and North Africa, the development in recent years of new types of wheat with a higher amount of cytotoxic gluten peptides, and the higher content of gluten in bread and bakery products, due to the reduction of dough fermentation time.

Labeling of Gluten in the United States

In the United States, gluten is not listed on labels unless added as a stand-alone ingredient. Wheat or other allergens are listed after the ingredient line. The US Food and Drug Administration (FDA) has historically classified gluten as "generally recognized as safe" (GRAS). In August 2013, FDA issued a final rule, effective August 2014, that defined the term "gluten-free" for voluntary use in the labeling of foods as meaning that the amount of gluten contained in the food is below 20 parts per million.

The "Thriller" Genre in Art

Thriller is a broad genre of literature, film and television, having numerous subgenres. Thrillers are characterized and defined by the moods they elicit, giving viewers heightened feelings of suspense, excitement, surprise, anticipation and anxiety. Successful examples of thrillers are the films of Alfred Hitchcock.

Thrillers generally keep the audience on the "edge of their seats" as the plot builds towards a climax. The cover-up of important information is a common element. Literary devices such as red herrings, plot twists, and cliffhangers are used extensively. A thriller is usually a villain-driven plot, whereby he or she presents obstacles that the protagonist must overcome.

Homer's Odyssey is one of the oldest stories in the Western world and is regarded as an early prototype of the thriller.

Characteristics

Writer Vladimir Nabokov, in his lectures at Cornell University, said: "In an Anglo-Saxon thriller, the villain is generally punished, and the strong silent man generally wins the weak babbling girl, but there is no governmental law in Western countries to ban a story that does not comply with a fond tradition, so that we always hope that the wicked but romantic fellow will escape scot-free and the good but dull chap will be finally snubbed by the moody heroine."

Thrillers may be defined by the primary mood that they elicit: suspenseful excitement. In short, if it "thrills", it is a thriller. As the introduction to a major anthology explains:

   Thrillers provide such a rich literary feast. There are all kinds. The legal thriller, spy thriller, action-adventure thriller, medical thriller, police thriller, romantic thriller, historical thriller, political thriller, religious thriller, high-tech thriller, military thriller. The list goes on and on, with new variations constantly being invented. In fact, this openness to expansion is one of the genre's most enduring characteristics. But what gives the variety of thrillers a common ground is the intensity of emotions they create, particularly those of apprehension and exhilaration, of excitement and breathlessness, all designed to generate that all-important thrill. By definition, if a thriller doesn't thrill, it's not doing its job.

                   — James Patterson, June 2006, "Introduction," Thriller

Major elements of a thriller

  • Suspense
  • Themes and Characters
  • Story and Setting
History in Literature

Ancient epic poems such as the Epic of Gilgamesh, Homer's Odyssey and the Mahābhārata use similar narrative techniques as modern thrillers. In the Odyssey, the hero Odysseus makes a perilous voyage home after the Trojan War, battling extraordinary hardships in order to be reunited with his wife Penelope. He has to contend with villains such as the Cyclops, a one-eyed giant, and the Sirens, whose sweet singing lures sailors to their doom. In most cases, Odysseus uses cunning instead of brute force to overcome his adversaries.

Little Red Riding Hood (1697), an early example of a psycho-stalker story, is a fairy tale about a girl who walks through the woods to deliver food to her sick grandmother. A wolf wants to eat the girl but is afraid to do so in public. He approaches Little Red Riding Hood and she naively tells him where she is going. He suggests the girl pick some flowers, which she does. In the meantime, he goes to the grandmother's house and gains entry by pretending to be the girl. He swallows the grandmother whole (in some stories, he locks her in the closet) and waits for the girl, disguised as the grandma.

The Three Apples, a tale in the One Thousand and One Nights (Arabian Nights), is the earliest known murder mystery and suspense thriller with multiple plot twists and detective fiction elements. In this tale, a fisherman discovers a heavy locked chest along the Tigris river and he sells it to the Abbasid Caliph, Harun al-Rashid, who then has the chest broken open only to find inside it the dead body of a young woman who was cut into pieces. Harun orders his vizier, Ja'far ibn Yahya, to solve the crime and find the murderer within three days. This whodunit mystery may be considered an archetype for detective fiction.

The Count of Monte Cristo (1844) is a swashbuckling revenge thriller about a man named Edmond Dantès who is betrayed by his friends and sent to languish in the notorious Château d'If. His only companion is an old man who teaches him everything from philosophy to mathematics to swordplay. Just before the old man dies, he reveals to Dantès the secret location of a great treasure. Shortly after, Dantès engineers a daring escape and uses the treasure to reinvent himself as the Count of Monte Cristo. Thirsting for vengeance, he sets out to punish those who destroyed his life.

The Riddle of the Sands (1903) is "the first modern thriller", according to Ken Follett, who described it as "an open-air adventure thriller about two young men who stumble upon a German armada preparing to invade England".

Heart of Darkness (1903) is a first-person within a first-person account about a man named Marlow who travels up the Congo River in search of an enigmatic Belgian trader named Kurtz. Layer by layer, the atrocities of the human soul and man's inhumanity to man are peeled away. Marlow finds it increasingly difficult to tell where civilization ends and where barbarism begins. Today this might be described as a psychological thriller.

The Thirty-Nine Steps (1915) is an early thriller by John Buchan, in which an innocent man becomes the prime suspect in a murder case and finds himself on the run from both the police and enemy spies.

The Manchurian Candidate (1959) by Richard Condon is a classic of Cold War paranoia. A squad of American soldiers is kidnapped and brainwashed by Communists. False memories are implanted, along with a subconscious trigger that turns them into assassins at a moment's notice. They are soon reintegrated into American society as sleeper agents. One of them, Major Bennett Marco, senses that not all is right, setting him on a collision course with his former comrade Sergeant Raymond Shaw, who has been activated as an assassin.

The Spy Who Came in from the Cold (1963) by John le Carré is set in the world of Cold War espionage and helped to usher in an era of more realistic thriller fiction, based around professional spies and the battle of wits between rival spymasters.

The Bourne Identity (1980) is one of the first thrillers to be written in the modern style that we know today. A man with gunshot wounds is found floating unconscious in the Mediterranean Sea. Brought ashore and nursed back to health, he wakes up with amnesia. Fiercely determined to uncover the secrets of his past, he embarks on a quest that sends him spiraling into a web of violence and deceit. He is astounded to learn that knowledge of hand-to-hand combat, firearms, and trade craft seem to come naturally to him.

1953 book: The Captive Mind

The Captive Mind (Polish: Zniewolony umysł) is a 1953 work of nonfiction by Polish writer, academic and Nobel laureate Czesław Miłosz, published in the English translation originally by Secker and Warburg. The work was written in Polish soon after the author received political asylum in Paris following his break with Poland's Communist government. It draws upon his experiences as an underground writer during World War II, and his position within the political and cultural elite of Poland in the immediate post-war years. The book attempts to explain both the intellectual allure of Stalinism and the temptation of collaboration with the Stalinist regime among intellectuals in post-war Central and Eastern Europe. Miłosz describes the book as having been written "under great inner conflict.”

Overview

 

The Captive Mind begins with a discussion of the novel Insatiability by Stanisław Ignacy Witkiewicz and its plot device of Murti-Bing pills, which are used as a metaphor for dialectical materialism, but also for the deadening of the intellect caused by consumerism in Western society. The second chapter considers the way in which the West was seen at the time by residents of Central and Eastern Europe, while the third outlines the practice of Ketman, the act of paying lip service to authority while concealing personal opposition, describing seven forms applied in the people's democracies of mid-20th century Europe.

The four chapters at the heart of the book then follow, each a portrayal of one of four gifted Polish men who capitulated, in some fashion, to the demands of the Communist state. They are identified only as Alpha, the Moralist; Beta, The Disappointed Lover; Gamma, the Slave of History; and Delta, the Troubadour. However, each of the four portraits is easily identifiable: Alpha is Jerzy Andrzejewski, Beta is Tadeusz Borowski, Gamma is Jerzy Putrament and Delta is Konstanty Ildefons Gałczyński.

The book elaborates the idea of "enslavement through consciousness" in the penultimate chapter, and closes with a pained and personal assessment of the fate of the Baltic nations in particular. Its list of chapters includes: 1. The Pill of Murti-Bing, 2. Looking to the West, 3. Ketman, 4. Alpha, the Moralist, 5. Beta the Disappointed Lover, 6. Gamma, the Slave of History, 7. Delta, the Troubadour, 8. Man, This Enemy, and 9. The Lesson of the Baltics.

Reception

The Captive Mind was an immediate success which was to bring its author international renown. While banned in Poland, it circulated underground there, Miłosz being among those authors whose name could not be mentioned even in order to denounce. The book is described by historian Norman Davies as a "devastating study" which "totally discredited the cultural and psychological machinery of Communism". In that the book represents the view of an insider and draws on extensive analysis, it has been compared to Darkness at Noon by Arthur Koestler and Nineteen Eighty-Four by George Orwell.

Miłosz has said of the book "It was considered by anti-communists as suspect because I didn't attack strongly enough the communists. I tried to understand the processes and they didn't like that. And it also created the idea, particularly in the West, that I was a political writer. This was a misunderstanding because my poetry was unknown. I have never been a political writer and I worked hard to destroy this image of myself
