Looking back: 1978

In 1978 I started senior high school (year 11 and 12). That was a year of terrorism – a bomb was exploded outside the Sydney Hilton Hotel by the Ananda Marga group (apparently in an attempt to kill Indian prime minister Morarji Desai), and former Italian prime minister Aldo Moro (below) was kidnapped and murdered by the Red Brigades. On a more positive note, John Paul II became the first Polish pope, and helped to chip away at the power of the Soviet Union.

That year also marked the debut of the soap opera Dallas and the comic strip Garfield. In science, James Christy at the United States Naval Observatory discovered Pluto’s moon Charon. We finally got a good look at it in 2015:

In computing, the Turing Award went to Robert Floyd, for his work in programming languages and algorithms. Intel introduced the 8086, the first of the x86 microprocessors which are still the most common CPUs in personal computers and laptops today. The game Space Invaders also had its debut:

The year 1978 also saw the release of the unsatisfactory animated version of The Lord of the Rings, and a number of interesting albums, including The Kick Inside by Kate Bush, Pyramid by The Alan Parsons Project, Dire Straits by the band of the same name, the electronic Équinoxe by Jean Michel Jarre, and Jeff Wayne’s Musical Version of The War of the Worlds:

Of the books published that year, The Road Less Traveled by M. Scott Peck, the exceedingly dark The House of God by Samuel Shem, and A Swiftly Tilting Planet by Madeleine L’Engle (below) stand out.

Stories of the Past and Future

Inspired by a classic XKCD cartoon, the infographic above shows the year of publication and of setting for several novels, plays, and films.

They fall into four groups. The top (white) section is literature set in our future. The upper grey section contains obsolete predictions – literature (like the book 1984) set in the future when it was written, but now set in our past. The centre grey section contains what XKCD calls “former period pieces” – literature (like Shakespeare’s Richard III) set in the past, but written closer to the setting than to our day. He points out that modern audiences may not realise “which parts were supposed to sound old.” The lower grey section contains literature (like Ivanhoe) set in the more distant past.

In praise of the codex

Charles Emmanuel Biset, Still life with Books, a Letter and a Tulip

The codex (book with pages) has been with us for about 2,000 years now. Because of advantages like rapid access to specific pages, it gradually replaced the older technology of the scroll:

Christians seem to have been early adopters of the codex technology. The oldest known fragment of the Christian New Testament, papyrus P52, dated to around the year 130, is a small fragment of a codex of the Gospel according to John (with parts of verses 18:31–33 on one side of the page, and parts of verses 18:37–38 on the other):

In 2010, Google estimated that the total number of published books had reached 130 million. At times it seems that e-books are taking over from the printed codex format, but there is a friendliness to the printed book that would make me sorry to see it go. I am not the only one.

Robert Darnton, in The Case for Books: Past, Present, and Future, writes: “Consider the book. It has extraordinary staying power. Ever since the invention of the codex sometime close to the birth of Christ, it has proven to be a marvelous machine – great for packaging information, convenient to thumb through, comfortable to curl up with, superb for storage, and remarkably resistant to damage. It does not need to be upgraded or downloaded, accessed or booted, plugged into circuits or extracted from webs. Its design makes it a delight to the eye. Its shape makes it a pleasure to hold in the hand.

How true that is!

I ♥ science books!

Looking back: 1989

In 1989, I started my first lecturing job, at Griffith University, Brisbane, Queensland. My PhD was all but finished and – more importantly – my scholarship money had run out. That was the year that Stanley Pons and Martin Fleischmann announced that they had discovered cold fusion. They had not. I’m glad that I was being more careful in my own work.

Konrad Lorenz, William Shockley, and Andrei Sakharov all died in 1989, while Isamu Akasaki developed the now-ubiquitous GaN-based blue LED. Tim Berners-Lee designed the World Wide Web, the Tiananmen Square protests took place, the Berlin Wall came down, George Bush became President of the USA, and the Soviet–Afghan War ended (Bush’s son was to start his own Afghan war in 2001).

The spaceprobe Voyager 2 (launched in 1977) visited Neptune in 1989, and took some lovely photographs.

In the world of cinema, Batman, Indiana Jones and the Last Crusade, and The Fabulous Baker Boys were released. Books of 1989 included The Remains of the Day by Kazuo Ishiguro, An Acceptable Time by Madeleine L’Engle, The Writing Life by Annie Dillard, and Wonderful Life by Stephen Jay Gould. An interesting year, on the whole.

The Man Who Knew Infinity: a book review

The Man Who Knew Infinity by Robert Kanigel (1991)

I recently, and somewhat belatedly, read Robert Kanigel’s The Man Who Knew Infinity, a biography of the brilliant Indian mathematician Srinivasa Ramanujan. A partly fictionalised film based on the book was released in 2015 (see Scott Aaronson’s review of the film here).

Whewell’s Court, Trinity College, Cambridge, where Ramanujan lived when he first arrived in England in 1914 (photo: Cmglee)

Ramanujan had one of the greatest mathematical intuitions of all time (he himself credited his insights to the goddess Namagiri). However, his brilliant guesses were as likely to be wrong as right. Furthermore, Ramanujan often neglected formal mathematical proofs, so that the work of separating the many diamonds from the occasional paste was frequently left to collaborators (like G. H. Hardy, who invited Ramanujan to England, and who wrote several joint papers with him). There are still results in Ramanujan’s journals which have neither been proved nor disproved (see this perspective on Ramanujan by Stephen Wolfram).

Interest in Ramanujan seems to have peaked at around the year 2000, according to Google Ngrams (although this does not include the influence of the recent film):

Google Ngrams search for Ramanujan’s name in books

I found Kanigel’s book a very enjoyable read. There is extensive biographical detail, albeit with a few misquotes, and with apparent confusion at times about the language of a century ago (e.g. the word “cult,” used in a technical sense to mean “a particular system of religious belief,” referring to the Brahmin version of Hinduism which Ramanujan followed). Kanigel does not quite succeed in fitting Ramanujan into a larger context – I would have liked a bit more discussion of Ramanujan by other mathematicians. And I cannot help but wonder what would have happened had illness (probably chronic hepatic amoebiasis, although Kanigel suggests tuberculosis) not killed Ramanujan at the tragically young age of 32. I guess nobody can imagine what further mathematics we might have seen.

See here and here for other reviews of the book.

Ecological literacy and Frank Herbert’s Dune, half a century on

Dune by Frank Herbert

The year 1965 saw the appearance of what has been called “the first planetary ecology novel on a grand scale.” Frank Herbert’s Dune explored a plethora of interesting themes, notably that of ecology. The novel speaks of “… teaching [the children] ecological literacy, creating a new language with symbols that arm the mind to manipulate an entire landscape, its climate, seasonal limits, and finally to break through all ideas of force into the dazzling awareness of order.

The use of food webs, like the one for waterbirds of Chesapeake Bay above, was fairly standard by 1965, and Herbert seems to be hinting at a graphical language for ecology going beyond that. Exactly what he was referring to is unclear.

But are we teaching the kind of ecological literacy Herbert refers to? A 2013 survey indicated that, out of 145 US tertiary institutions ranked for “Ecology and Evolutionary Biology” and “Integrative Biology,” only 47% taught a course in ecosystem ecology or biogeochemistry, and only 22% of the courses included field experiences. A 1993 survey of UK secondary teaching (A-levels and GCSE) showed that students only studied a median of 2 or 3 different habitats:

So how many children actually understand, say, trophic cascades in the wolf–elk ecosystem? How many adults, for that matter? The evidence suggests that it’s not very many, judging by the resistance to sensible management of National Parks. If we do not wish to recreate the desert planet Arrakis, we might like to work on that.

Colour in literature

The chart below extends my previous colour analysis to an even more mixed collection of books. On the right are books with many descriptive passages involving colour, and thus a high frequency of colour words (calculated without excluding stop words this time). At the top of the chart are books with large colour vocabularies (counting colour words used twice or more). The dots show the most common colour word in each book.

Results are consistent with the fact that the most common colour words in English (in decreasing order of frequency) are black, white, red, green, blue, yellow, brown, grey, pink, orange, and purple. However, Anne of Green Gables and The Wonderful Wizard of Oz have “green” as the most common word for plot-related reasons, while The Blue Castle by L.M. Montgomery has, not surprisingly, “blue.” The Merry Adventures of Robin Hood by Howard Pyle has “scarlet,” some uses of which are as the name “Will Scarlet.” Twenty Thousand Leagues Under the Sea I have already discussed.
