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.”

Education and Ambiguity Awareness: A Polyvalent World

Sleepwalkers and sleepwalking are both destructive and constructive and show us the ambiguity in all phenomena.

The World War I chronicle of Professor Christopher Clark, The Sleepwalkers, from 2012, is described this way:

On the morning of June 28, 1914, when Archduke Franz Ferdinand and his wife, Sophie Chotek, arrived at Sarajevo railway station, Europe was at peace. Thirty-seven days later, it was at war. The conflict that resulted would kill more than fifteen million people, destroy three empires, and permanently alter world history.

The Sleepwalkers reveals in gripping detail how the crisis leading to World War I unfolded. Drawing on fresh sources, it traces the paths to war in a minute-by-minute, action-packed narrative that cuts among the key decision centers in Vienna, Berlin, St. Petersburg, Paris, London, and Belgrade.

Distinguished historian Christopher Clark examines the decades of history that informed the events of 1914 and details the mutual misunderstandings and unintended signals that drove the crisis forward in a few short weeks.

How did the Balkans—a peripheral region far from Europe’s centers of power and wealth—come to be the center of a drama of such magnitude? How had European nations organized themselves into opposing alliances, and how did these nations manage to carry out foreign policy as a result? Clark reveals a Europe racked by chronic problems—a fractured world of instability and militancy that was, fatefully, saddled with a conspicuously ineffectual set of political leaders. These rulers, who prided themselves on their modernity and rationalism, stumbled through crisis after crisis and finally convinced themselves that war was the only answer.

On the other hand, the great science writer and intellectual Arthur Koestler (died in 1983) in his own book, The Sleepwalkers, (originally, 1959) argues that the revolution in cosmology associated with the names of Copernicus, Kepler, Galileo, et al depended on visionary thinking, a kind of “sleepwalking.”

Lastly, the classic novel, The Sleepwalkers by Hermann Broch (died in 1851) condemns sleepwalking as the basis of Europe and Germany’s descent into nightmare.

Important works by Broch are The Sleepwalkers (German: “Die Schlafwandler,” 1932) and The Guiltless (German: “Die Schuldlosen,” 1950). The Sleepwalkers is a trilogy, where Broch takes “the degeneration of values” as his theme. Various generations are depicted as sleepwalking through their times and eras without any ability to “see past” their time, place, era. They were “sleepwalking.” This made them liable to demagogic deceptions and recruitment.

On the other hand, the experience and story of Kekulé (died 1896) and his scientific discoveries prodded by dreams and reveries and sleepwalking give us a story that argues against seeing sleepwalking as always negative:
Kekulé’s dream and “good kinds of sleepwalking.”

Friedrich August Kekulé, later Friedrich August Kekule von Stradonitz (7 September 1829 – 13 July 1896), was a German organic chemist. From the 1850s until his death, Kekulé was one of the most prominent chemists in Europe, especially in theoretical chemistry. He was the principal founder of the theory of chemical structure.

The new understanding of benzene (C6H6), and hence of all aromatic compounds, proved to be so important for both pure and applied chemistry after 1865 that in 1890 the German Chemical Society organized an elaborate appreciation in Kekulé’s honor, celebrating the twenty-fifth anniversary of his first benzene paper.

Here Kekulé spoke of the creation of the theory.

He said that he had discovered the ring shape of the benzene molecule after having a reverie or day-dream of a snake seizing its own tail (this is an ancient symbol known as the ouroboros).

Kekulé’s story of “dreaming up” the structure of benzene (C6H6) gives us another historical example of Arthur Koestler-type “good sleepwalking” ie visionary dreams and reveries that really enhance “objective” concrete scientific analysis and not only art works.

It is educational to see the inner ambiguity of words and phenomena (such as sleepwalking) because this duality and “polyvalence” applies to many cases.
