Movies and Chemistry: Keeping the Enchantment of Education

Several movies give you an “enchanting” back door or window into chemistry so that you can “beat” the tediousness of regular education and come into the field and its topics via these movies:

I.

The Man in the White Suit is a 1951 British comedy classic with Alec Guinness as a genius research chemist. He fiddles with his flasks and polymer and textile chemistry experiments until he invents a fabric that shows no wear and tear “forever.” This would seem like a great boon to humanity in its clothing needs but the chemist (“Sidney Stratton”) finds that both labor and management reject his discovery violently as it threatens jobs and profits. Textile or fabric polymer chemistry is at the heart of the plot.

Cry Terror! is a taut 1958 crime thriller movie with James Mason and Rod Steiger. The plot involves the terrorist threat of exploding a domestic airliner with a hidden RDX cache (a TNT successor) unless the demanded payment is made.

RDX was used by both sides in World War II. The U.S. produced about 15,000 long tons per month during WWII and Germany about 7,000 long tons per month. RDX had the major advantages of possessing greater explosive force than TNT, used in World War I and requiring no additional raw materials for its manufacture.

Semtex is a general-purpose plastic explosive containing RDX and PETN. It is used in commercial blasting, demolition, and in certain military applications.

A Semtex bomb was used in the Pan Am Flight 103 (known also as the Lockerbie) bombing in 1988. A belt laden with 700 g (1.5 lb) of RDX explosives tucked under the dress of the assassin was used in the assassination of former Indian prime minister Rajiv Gandhi in 1991.

The 1993 Bombay bombings used RDX placed into several vehicles as bombs. RDX was the main component used for the 2006 Mumbai train bombings and the Jaipur bombings in 2008. It also is believed to be the explosive used in the 2010 Moscow Metro bombings.

Traces of RDX were found on pieces of wreckage from 1999 Russian apartment bombings and 2004 Russian aircraft bombings. Further reports on the bombs used in the 1999 apartment bombings indicated that while RDX was not a part of the main charge, each bomb contained plastic explosive used as a booster charge.

Ahmed Ressam, the al-Qaeda Millennium Bomber, used a small quantity of RDX as one of the components in the bomb that he prepared to detonate in Los Angeles International Airport on New Year’s Eve 1999-2000; the bomb could have produced a blast forty times greater than that of a devastating car bomb.

In July 2012, the Kenyan government arrested two Iranian nationals and charged them with illegal possession of 15 kilograms (33 pounds) of RDX. According to the Kenyan Police, the Iranians planned to use the RDX for “attacks on Israeli, U.S., UK and Saudi Arabian targets.”

RDX was used in the assassination of Lebanese Prime Minister Rafic Hariri on February 14, 2005.

In the 2019 Pulwama attack in India, 250 kg of high-grade RDX was used by Jaish-e-Mohammed. The attack resulted in the deaths of 44 Central Reserve Police Force personnel as well as the attacker.

Semtex was developed and manufactured in Czechoslovakia, originally under the name B 1 and then under the “Semtex” designation since 1964, labeled as SEMTEX 1A, since 1967 as SEMTEX H, and since 1987 as SEMTEX 10. Originally developed for Czechoslovak military use and export, Semtex eventually became popular with paramilitary groups and rebels or terrorists because prior to 2000 it was extremely difficult to detect, as in the case of Pan Am Flight 103.

The Russian apartment bombings were a series of explosions that hit four apartment blocks in the Russian cities of Buynaksk, Moscow and Volgodonsk in September 1999, killing more than 300, injuring more than 1,000, and spreading fear across the country. The bombings, together with the Invasion of Dagestan, triggered the Second Chechen War. The handling of the crisis by Vladimir Putin, who was prime minister at the time, boosted his popularity greatly and helped him attain the presidency within a few months.

The blasts hit Buynaksk on 4 September and in Moscow on 9 and 13 September. On 13 September, Russian Duma speaker Gennadiy Seleznyov made an announcement in the Duma about receiving a report that another bombing had just happened in the city of Volgodonsk. A bombing did indeed happen in Volgodonsk, but only three days later, on 16 September. Chechen militants were blamed for the bombings, but denied responsibility, along with Chechen president Aslan Maskhadov.

A suspicious device resembling those used in the bombings was found and defused in an apartment block in the Russian city of Ryazan on 22 September. On 23 September, Vladimir Putin praised the vigilance of the inhabitants of Ryazan and ordered the air bombing of Grozny, which marked the beginning of the Second Chechen War. Three FSB agents who had planted the devices at Ryazan were arrested by the local police, with the devices containing a sugar-like substance resembling RDX.

II.

The movie Khartoum (1966) has General Charles Gordon traveling to Sudan in 1884 to quell the “mad mullah” the Mahdi. (Osama bin Laden of his day).
At the train station where General Gordon starts his trip, there’s a railway ad sign that promotes the use of “Wright’s Coal Tar Soap.”

This gives us a sign of the rise of the modern chemical industry.

III.

Think of “Sherlock Holmes” in terms of all the movies and TV series or the original stories and books:

Holmes has to explain to Watson how he survived the assassination attempt on him by Moriarty, “the Napoleon of Crime” who threw him off the Reichenbach Falls. Holmes explains that he faked Moriarty out and clung to a bush or something and was (obviously) not killed.

Holmes tells Watson what he does when he returns to civilization and travels and studies for some three years:

“I then passed through Persia, looking in at Mecca, and paid a short but interesting visit to the Khalifa at Khartoum, the results of which I communicated to the Foreign Office. Returning to France, I spent some months in a research into the coal-tar derivatives, which I conducted in a laboratory at Montpellier, in the south of France.”

The context implies the year 1894.

There is clear evidence that Mr. Holmes was deeply involved in the research of coal-tar derivatives as early as 1889 when the events of the Copper Beeches matter were transpiring.

We are told that on an evening in 1889, Mr. Holmes was seated in 221B Baker Street at the deal table loaded with retorts and test tubes. He was settling down to one of those all-night chemical researches in which he frequently indulged.

The research work was interrupted by a message of distress from Violet Hunter. Watson found that there was a train the next morning, and Holmes tells Watson:

“That will do very nicely. Then perhaps I had better postpone my analysis of the acetones as we may need to be at our best in the morning.”

It is clear that Holmes was engaged in coal-tar research long before his visit to Montpellier in the south of France.

The quotation from the Copper Beeches story refers to acetones, not to coal-tar derivatives.

“In the fractional distillation of coal-tar, the distillate separates into five distinct groups or layers, depending upon the stage of the process and the amount of heat applied. Category-one of the five includes benzene, toluene, xylenes and cumenes.

Acetones [dimethelketone-CH3COCH3] may be derived from the oxidation of cumene. And cumene [isopropylbenzene-C6H5C(CH3)2] is derived by distillation from the coal-tar naphtha fractions.”

Cumenes are derived from coal-tar, and acetones are derived from cumenes. Thus, a study of the acetones is, necessarily, research into coal-tar derivatives.

The rise of chemical engineering and organic chemistry are at the heart of the Sherlock Holmes stories.

Thus we can “climb” into chemistry via these books and movies and keep a feeling of enchantment as a kind of educational “shoehorn.”

Essay 73: Signs and Meanings: Education and Semiotics

One learns to function in a world of posters, postings, signs, ads, ordinances, notices and indications of “material culture” (i.e. commerce expressed in designs and slogans on walls and buses, subway cars, etc.).

Think of the 1963 movie The Great Escape. There’s a scene where James Coburn’s Australian character is sitting in an outdoor cafe on the French/Spanish border and the waiter comes over to him and pulls him toward the counter and says, “Telephon, monsieur.”

The James Coburn character has no idea why this is happening but mimics the proprietor and son when they duck down. French Resistance fighters in a car gun down the Germans at the cafe and James Coburn’s character “gets it” and asks them for help to get into Spain. As he ducks down you see posted on the wall of the cafe several ad signs for drinks. One of them is “Byrrh”:

“Byrrh is an aromatised wine-based apéritif made of red wine, mistelle, and quinine. Created in 1866 and a trademark since 1873, it was popular as a French apéritif. With its marketing and reputation as a ‘hygienic drink,’ Byrrh sold well in the early 20th century.” (from Wikipedia)

In many French movies or movies set in France, such as Belle de Jour and The Legend of the Holy Drinker from 1988 (in which a drunken homeless man [played by Rutger Hauer] in Paris is lent 200 francs by a stranger as long as he promises to repay it to a local church when he can afford to; the film depicts the man’s constant frustrations as he attempts to do so).

“Byrrh” appears routinely and a French child begins to ‘get the picture’ on what is being signified and how it differs from other notices, commercial or legal or municipal.

Set in Paris, the ad notice “Byrrh” appears in the same way you’d expect to see “Coca-Cola” and know what the sign signifies. “Coke” is a drink and not the fuel coke. How exactly you make these distinctions is unclear to linguists and other language-watchers. It’s a social phenomenon, partly, like mores and manners.

In the movie The Book Thief (a 2013 World War II war drama, starring Geoffrey Rush, Emily Watson, and Sophie Nélisse, based on the 2005 novel) there’s a moment when you see a sign advertising or reminding you of “Kolonialwaren” (i.e., colonial wares) which was the German way of pointing to a place or store that sold coffee, tea, cocoa, etc. Any German adult of the period would know what “Kolonialwaren” signifies without quite knowing how he or she knows.

A traffic sign (you have to of course realize it’s a traffic sign and not some commercial ad) tells you “Boston 20 m.” You realize or guess it means 20 miles and not 20 meters (since meters are not a typical American measure) nor would it be 20 minutes since that would assume everyone is driving at a speed that gives you 20 minutes, which is far-fetched.

How a person goes from birth to adulthood whereby they spontaneously navigate a welter of different signs and postings, ads and statutes is quite opaque.

Roland Barthes (died 1980) explored this domain of signs (not only physical signs but mythology as a system of signs) all his life:

Barthes is one of the leading theorists of semiotics, the study of signs. A sign, in this context, refers to something which conveys meaning – for example, a written or spoken word, a symbol or a myth.

Education should not ignore “material culture” (i.e., the history of things) and semiotics (i.e., the world “speaking” to you via designs and signs and words).
