Dan Browned: Dan Brown
Dan Brown, Trope Namer of Dan Browned, gets his own page due to the absolutely monstrous amount of the eponymous activity found in his myriad works. Due to the scrapping of the last page due to natter, ill-will, et. al., there is such a thing as notability. Citations are done like the following:

Moreover, anything about religious inaccuracies will not be represented on this page, due to a) The Bible being a work with wide interpretations. b) Rule of Cautious Editing Judgement, unless it a) directly contradicts one of the few indisputable things about the Bible (e.g. the text of a passage) or b) makes clearly claims about the doctrines of a particular sect (e.g. claims respecting Catholic theology unsupported by anything in Catholic literature).

    Digital Fortress 
  • The depiction of Seville has been criticized by Spanish-speaking readers, among other things. [Spanish] Is Dan Brown a compulsive liar?
    • This one was simply insulting - Brown portrayed the Spanish healthcare system as useless and incompetent - in fact, it is ranked 7th in the World by the WHO (for comparison, the USA's is 37th).
    • The whole issue is summed up by Brown's claim that he studied Art History in the Univeristy of Seville for a year. Not only does the University deny this, but Brown also gets his Art History wrong in the book (saying that the 15th century cathedral is from the 11th century, that it has only one door when it has seven, and making a plot point out of the dangerous steps of the Giralda - a building notorious for not having any steps, only ramps).
  • The book states that the etymology of "sincerely" is a combination of two Latin works "sine" and "cera", meaning "without wax". A popular, but entirely wrong, urban legend. Storied Words by Jeff Jeske
  • The book confuses how the number of bits in a key scales; specifically it states that a 64 bit key has twice as many combinations as a 32 bit key. It actually has 4,294,967,296 (2^32) times as many possibilities. WordLingo
    • The book also confuses the purpose of a public key with that of a private key.
    • Not to mention his claim that a 64-bit key would have 64 characters, "too many for anyone to remember." In hexadecimal, a 64-bit key has 16 characters.
  • The atomic elements made to create the bombs dropped on Nagasaki and Hiroshima were different (plutonium and uranium) and not just two different isotopes of uranium. That doesn't fit with the story of course...
  • The book has a short description involving decrypting a code that is wrong on several levels. The code was thought by the characters to be "Mandarin symbols" but is later discovered to be the "Kanji language". First, Mandarin is a spoken language that shares its written symbols with many other Sinic languages. Assuming that by "Mandarin characters" he meant Classical Chinese or Standard Written Chinese (which is likely), there is no way to tell from the writing whether the writer spoke Mandarin, Cantonese, or any other dialect; it's all just written in Chinese.note  Second, kanji is one of three symbol sets used by Japanese speakers; it is not a language of its own. Third, and perhaps most importantly, Chinese zi and Japanese kanji are the same symbols, written the same way and carrying the same meaning, but pronounced differently when spoken aloud. This would be tantamount to looking at the word 'tomato' and determining whether it should be "to-MAY-to" or "to-MAH-to"—or more to the point, whether the character "8" should be understood as saying "eight" in English or "huit" in French when looking at the "phrase" "8+7=15." Finally, the code is decrypted out of sequence, for security purposes. Translating Chinese or Japanese out of sequence would be just as impossible as reading English words scrambled by a randomizer. [1]
  • That's not even to mention the central conceits of the book, which are that 1. the NSA has a computer that can carry out successful brute-force attacks on modern cryptographic systems (which is basically theoretically impossible within the lifetime of the user, unless they've gotten new technology from Sufficiently Advanced Aliens), and 2. some person invented a cryptosystem that is immune to brute-force attacks, and yet is not simply a one-time pad, which is theoretically impossible due to the fundamental nature of information.
  • One plot point is that the magical algorithm is publicized, but encrypted with itself, and everyone acts as if anyone who got the key can decrypt and use it. This ignores the fact that a cryptographic key is useless without also knowing the algorithm. Reverse-engineering an algorithm when one got a key and a ciphertext sample (but no cleartext sample) might be theoretically possible when the algorithm isn't very complex, but when the algorithm is as sophisticated as claimed, this would be everything but trivial.
  • It's a major plot point that the NSA's (fictional) supercomputer cannot decrypt a particular ciphertext which it received recently. This is taken as absolute proof that the cipertext was encrypted with some sort of Ultimate Encryption Technique which is tough enough to beat the supercompuer. Absolutely no one mentions the obvious alternative: the supposed ciphertext is simply random data, and it can't be decrypted simply because it's random and therefore it contains no actual information.
  • In the book, the aforementioned ciphertext turns out to be a virus. It was quickly decrypted and subsequently infected all sorts of critical computers. But this makes no sense at all. The only way a virus can attack a machine is if the machine executes the file. (This may happen with a standalone virus file, or with a virus that's embedded into a larger executable file somehow.) But there is absolutely no reason why the supercomputer should attempt to execute every file which it has decrypted! Most of the time you'd only want to read the file. If you did want to execute it, there would surely be another step where somebody has to click "ok", and even then there'd be sandboxing and whatever other protections in place to prevent attacks. I mean really, if the NSA had a policy of running every file it decrypts (without protection!), anyone in the world could just encrypt a common virus, email it to the NSA, and the NSA would be screwed.
    • As the ciphertext is supposed to be encryption software, perhaps the NSA had their computer attempt to run it to test whether the key was correct? It's mentioned at one point that there is some sandboxing, but they turned it off because it wouldn't let the Digital Fortress code run.
      • Most groups relying on computer systems work under the assumption that any unknown program, file or website refusing to work while using security measures like sandboxing is bad news and should be flushed. Turning off sandboxing to run it is like pointing a gun at your head and pulling the trigger to see if its loaded.
    • On the other hand, if the codebreaking software had its own security flaws, feeding it some carefully constructed input might well trick it into executing a malicious payload...exploiting a buffer overflow bug to run some shellcode, for example. This would require specific knowledge of the workings of the NSA's own software, of course.
  • The Digital Fortress algorithm relies on a technique called "rotating cleartext". This makes absolutely no sense if you know what cleartext is.
    • Maybe someone wrote the thing while spinning?

    Angels and Demons 
  • A bomb made by anti-matter to blow up the Vatican? There hasn't been enough anti-matter produced in the world to boil a cup of coffee....
    • Also, to make a bomb out of anti-matter they would have to have several huge and very, very rich backers. It's been estimated that to produce even one gram of antimatter would cost $25 billion, and they'd need more than one gram. Anti-matter is extremely expensive to make, and then there's the problem of transporting the stuff to the Vatican without it blowing up along the way. It'd be much easier and cheaper (even for CERN) to just use regular bombs.
  • Improper use of the Italian language was noted by Italian readers, along with generally being wrong about things pertaining to Rome. (Italian) Thriller Reviews
  • Contrary to what the book claims, Anti-matter can't be used as a source of limitless energy due to it taking more energy than it produces. CERN
  • No, CERN can't blow up the world whenever it wants like in the book. It doesn't have enough antimatter, for starters. History.com
    • Although a major plot device was that two scientists at CERN secretly developed a method for collecting bomb-level amounts of antimatter, and one was killed to get it. It was stated in the book that they could not achieve such levels until the characters discovered the fictional method.
  • A news commentator says that Ventresca was elected pope by "Adoration" when the crowd cheered him after they thought he had saved Vatican City from the antimatter. First, the proper term is "Election by Acclamation". Second, although Election by Acclamation hadn't been used since 1676, it became impossible in 1996 by Papal decree. Third, Acclamation required a spontaneous unanimous proclamation by the electors present (not the crowd outside) that a person should be Pope. A crowd cheering somebody's name would not be sufficient. Wikipedia
    • The film version has the Cardinals discussing electing the Camerlengo in this manner, since he wouldn't be eligible otherwise. Again, a requirement of Acclamation was spontaneity. As in, the electors had to proclaim the election without negotiation or consultation. This was based on the belief that the Holy Spirit moved the electors to declare that God had chosen the person.
    • Also, unlike the film claims, any Catholic man can be elected as pope, even a layman. (If a layman is elected, he has to be first ordained deacon, then priest, and then consecrated as bishop, after which he can take office.) Wikipedia
    • In the novel, it was the "electors present", not only the crowd, that cheered: all the cardinals were moved by the crowd to chant, and in doing so, gave their consent. The other two points are valid, however.
  • The book maintains that CERN created the Internet, which was created by the USA's Department of Defense's DARPA military technology research organization. CERN created the World Wide Web, which is not the same thing. This is exceptionally odd since Brown got it right in Digital Fortress. Pages 7 & 20–21 of Angels & Demons, Niels Brügger's Web History (2010)
  • The book describes Langdon as a professor of Symbology at Harvard. Symbology is not a department at Harvard (or at any university for that matter) — the real-life discipline is called Semiology (as in "semantics", not "half"). Slate
    • Later books seem to retcon this one by having him refer to himself as an Art History professor, though "and Symbologist" tends to get tacked on.
  • The book claims that the church Santa Maria della Vittoria is located at the Piazza Barberini, while in fact it's a bit to the west in one of the streets leading to it. Wikipedia
  • Langdon wonders whether the second altar of science could be located in St. Peter's Square due to the fact that it's part of Vatican City rather than Rome and all the altars are supposed to be found within the boundaries of the city of Rome. It's explained to him that St. Peter's Square has been contested territory between the authorities of Rome and those of Vatican City for centuries. The only problem with that is that Vatican City as an independent entity was established as late as 1929; before that everything that forms today's Vatican City was just as Roman as any other part of Rome.

    Deception Point 
  • The novel mentions special "Improvised munitions"- weapons that are capable of firing water at sufficient speed to shatter bones or turn sand or ice into bullets. In reality, "Improvised Munitions" in military jargon means something else entirely, and of those possibilities mentioned, only the first one is feasible, water bullets are use in bomb disposal since it is incompressible and a poor conductor of electricity. Turning sand into glass bullets however, would require a power source too big to conveniently carry and ice bullets were shown to be ineffective. Mythbusters.
  • Director Pickering addresses Rachel as "Agent Sexton". Intelligence analysts are not law enforcement officers and the NRO does not have clandestine field operatives. Wikipedia
  • NASA sets up a huge camp in Ellesmere Island and does all its business unhindered. Not only is Ellesmere Island part of Canada, who would presumably also want to take part in this, they already have a base there: Canadian Forces Station Alert (Wikipedia).
    • Not to mention that CFS Alert is a military signals intelligence intercept facility run jointly by the Canadian military's intelligence division and CSEC (the Canadian equivalent of the NSA) Wikipedia so chances are they would have at least noticed a strange radio transmission, like the one made by the murdered geologist
  • Japan's Seven Gods of Good Fortune (Shichi-fukujin) are misidentified as Shichigosan, which is something completely different. Wikipedia 1&Wikipedia 2

    The Da Vinci Code 
  • Right in the fraking title. "The [My-Father-Was-]From-Vince Code" should be a red flag to Leonardo Da Vinci studiers of the Dan Browning from the very title. SF Gate Article
    • It was fixed in some of the translations of the novel, such as Bulgarian, Czech, and Polish, all of which included the name Leonardo in their titles.
      • They also (at least as far as the Polish translation goes) substituted basically all of the "Da Vincis" found throughout the novel with the much more accurate "Leonardos."
      • Interestingly enough, that was not the case with the Polish title of the movie which is just as erroneous as the original.
  • Brown claims that Rosslyn Chapel has the same layout as the Temple of Solomon. According to real experts: "Rosslyn Chapel bears no more resemblance to Solomon's or Herod's Temple than a house brick does to a paperback book." Rosslyn and the Grail
  • No, Leonardo Da Vinci was not "flamboyantly homosexual". No law-abiding citizen was 'flamboyantly' anything besides heterosexual due to the laws of the time. The Da Vinci Hoax
    • Also, the standard of acceptable casualty between genders has fluctuated greatly over the centuries, and the terms "homosexual" and "heterosexual" themselves only date to the last century or so. The terms, and almost certainly their standards, would be alien to Leonardo.
  • The Knights Templar didn't do anything besides conquer and maintain territory in the Levant. They were also largely illiterate and likely uneducated, thus making it improbable that they passed down any kind of geometry from Egyptians or the like. The Knights Templar: A New History., p.2
    • The Templars were excellent bankers and their ranks contained many acclaimed scholars. But as for passing down ancient wisdoms go, they weren't superior to any other political or religious power group of their period.
  • Louvre Pyramid is composed of 673 panes of glass, not 666 panes of glass as in the book. GlassWeb
  • If there are any descendants of Jesus, it'd be a sizeable group, not a select few. Slate To be fair, a multitude of descendants isn't important when tracing a royal lineage.
  • In the description of Madonna Grotto John the Baptist is on the right, blessing Jesus on the left and being threatened by Virgin Mary. Aside from the... weird interpretation of this protective gesture, here's another version of Madonna Grotto. A staff with a cross on it is John the Baptist's symbol. Which kid has it?
  • Brown claims that counting the number of hands in "The Last Supper" leads to the discovery of a disembodied hand holding a knife. However, this hand clearly belongs to Peter. It being pointed away from Jesus is thought to symbolize Peter's violent reaction to Jesus' arrest.
  • What about that monk from Opus Dei? Even though Opus Dei was specifically founded for people who live "in the world"? (In other words, people who aren't members of religious orders.)
  • Ironically, Dan Brown did absolutely no research whatsoever on albinism. Silas has red eyes, shoots people from a far distance, and drives a car at high speeds at night. As outlined here by Dennis Hurley, writer and star of the parody film The Albino Code and an actual person with albinism, human albinos do not have red eyes; their eyes are blue or slate gray but may appear to be red-tinged due to the reflection of blood vessels in the eye, caused by a lack of pigmentation in the iris. Furthermore, most albinos have very poor vision and are often legally blind as the result of abnormal development of the retina and abnormal patterns of nerve connections between the eye and the brain. In fact, vision impairment is the main aspect of the diagnostic criteria for albinism. All in all, definitely not the best candidates for that assassin position. (More information here.)
  • Also Constantine the Great and the First Council of Nicea had nothing to do with making Christianity the official religion in the Roman Empire. Constantine only made it a legal religion, and the Council decided on questions like the divinity of Christ. It was Emperor Theodosius 65 years later who declared Christianity to be the state religion.
  • The idea that papyrus could easily be destroyed by vinegar. Papyrus is sturdy enough to hold itself together for 2-3 millenia and vellum can survive for hours sunken in concentrated hydrochloric acid. A few drops of vinegar would just make some stains.
  • Teabing and Langdon explain that English is the preferred mode of communication by the Priory of Sion as it is the "Lingua Pura", the pure tongue, the only European language unadulterated by the Papist Latin. While there really is no European language that was not influenced by Latin to some degree, the choice of English is particularly stupid. While it is a Germanic language (as opposed to Latin, which is in the Romance language family), it has borrowed heavily from French (a Latin-derived language) due to the Norman Conquest and later from Latin directly during the Renaissance. There is really no reason for the Priory to communicate in English when there are so many other languages that fit the criteria better like Russian, Turkish, Arabic, Hebrew, or Greek (all of which Renaissance scholars, but obviously not Brown, knew well about, and several of which—particularly Arabic,note  Hebrew,note  and most especially Greeknote ). The Real History Behind the Da Vinci Code
  • Teabing and Langdon explains the whole idea of upward pointed arrows representing a lance, or penis, while a downward pointing arrow is a chalice, or vulva. Teabing then tries to connect this to military insignia, claiming that "the more penises a solider has, the higher his rank." A quick glance at American and British Army ranks, to provide two examples out of the whole world, will show that the lower ranks use both symbols, and officer ranks use neither.
  • According to the book the Dead Sea Scrolls contain Christian gospel. In reality they were created by the Essenes sect of Jews and don't contain any gospels. University of Chicago

    The Lost Symbol 
  • Langdon states that the word "Abracadabra" means "I create as I say" and is based on the word "Abrahadabra". The translation is more or less correct, however he reverses the origins. Abrahadabra is from a 20th century new age religion called Thelema, while Abracadabra was used by 2nd century Romans. Wikipedia
  • Brown repeats the urban legend regarding the etymology of "sincerely" from Digital Fortress. Storied Words by Jeff Jeske
  • While its true that many of the experiments done by Katherine Solomon have been done in real life, they're hardly the conclusive truth as presented in the book. Masaru Emoto did do experiments on how thoughts could change the structure of water crystals, but they've been highly criticized- Emoto did not have controls on his experiment and has not given out his technique for others to attempt to repeat, and he's acknowledged that he just chose the pictures he liked best. The triple blind study conducted to try to replicate the effects failed to get significant results. "[2]" The main reason Noetic has been decried as pseudoscience is because many of its experiments aren't falsifiable. If you didn't get the expected result, then you just didn't do it right.

    Inferno 
  • Misquoting Robert Oppenheimer as saying "I have become Vishnu, destroyer of worlds". Actual quote: "Now I am become Death, the destroyer of worlds. Wikiquote on this
  • The opening quote, "The darkest places in hell are reserved for those who maintain their neutrality in times of moral crisis", is not found anywhere in Inferno. In fact, it is more recent than Dante. This is actually said by John F. Kennedy on West Germany Peace Corps (change from "darkest" to "hottest"), and later used by Martin Luther King, Jr. on the Vietnam War. Incidentally, the lowest level of Dante's Inferno is reserved for traitors. JFK Library
