Bill Hayden might today be recalled as the unluckiest man in politics: Bob Hawke replaced him as Labor leader on the same day that Malcolm Fraser called an election that Hayden, after years of rebuilding the Labor Party after the Whitlam years, was well positioned to win. But to dismiss him thus would be to overlook his very real and laudable efforts to make a difference in politics – as an early advocate for the decriminalisation of homosexuality, and as the social services minister who introduced pensions for single mothers and Australia’s first universal health insurance system, Medibank. Dismissing Hayden would also cause us to miss the counterpoint he provides to Peter Dutton, current leader of the Liberal Party.

When amateur historian Catherine Corless wrote in the Journal of the Old Tuam Society (2012) that the bodies of 796 children who had died in Tuam’s Mother and Baby Home between 1925 and 1961 might have been interred in a disused septic tank within the home’s grounds, she supposed her involvement in the search for truth would be at an end. The article, she expected, would prompt academics, politicians, and law enforcement agencies – not to mention the Bon Secours nuns who ran the home – to begin their own inquiries.

I first met Boris Frankel when he was a thirteen-year-old, in the pages of a file at the National Archives of Australia. I was working on Russian migrant families in Australia that decided to return to the Soviet Union, but then tried to come back to Australia. Boris and his sister Genia had travelled more than 1,500 kilometres from the Crimea to Moscow, alone, in 1959, in the hopes of persuading British authorities to allow their return to Australia. It was a remarkable story: two teenagers who negotiated Soviet bureaucracy and surveillance, made an impassioned plea, and secured the support of a British ambassador. The file even contained letters the children had written to Prime Minister Robert Menzies – their own, teenaged voices. Letters like this are a historian’s dream: I felt I had got to the heart of the story. And yet, in Boris Frankel’s historical memoir, No Country for Idealists, I saw the trip to Moscow anew. In the texture of Frankel’s narrative – their Siberian cabin-mate on the train journey (named Rasputin!), the ambassador’s chef who cooked them breakfast – the wonder of the journey emerged afresh.

Two of the defining figures of our age are China’s President Xi Jinping and Russia’s President Vladimir Putin. Both are authoritarian rulers intent on reshaping the global Western-led order. They despise and mistrust the United States equally, and, to justify their hold on power, promote a nationalist and civilisationist vision that elevates the long historical and cultural roots of their societies. They have defined themselves as indispensable for their respective countries’ futures and standing in the world.

Melanie Joosten’s third novel follows three women who are brought into contact during the fight for British women’s suffrage. Beatrice Taylor, captivated by the movement, becomes a full-blown militant. Her college roommate Catherine Dawson stays out of the direct struggle, preferring to advance women’s rights through a trail-blazing career in scientific research. Ida Bennett, a widow, supports herself and her children as a warden in Holloway Prison. Although sympathetic to the cause of women’s emancipation, when the suffragettes are jailed she is responsible for disciplining them.

On the surface, this encyclopedic work offers a gloriously lyrical exploration of the sea. It could be part of a recent shoal of books about the more-than-human world, limning the wondrous and astonishing. In Deep Water: The world in the ocean, whales learn rhyme-like patterns to remember their songs, a ‘babel of strange, eerie sounds: skittering blips, long cries, whoops and basso moans’. A loggerhead turtle travels more than 37,000 kilometres to return to her birthplace. Sharks’ chemo-receptors prove acute enough to detect blood ‘in amounts as low as one part in a million’. Port Jackson sharks socialise with their peers, and evidence emerges that some fish species use tools.

Gore Vidal (1925–2012) emphatically rejected any conventionally religious version of an afterlife. In an essay, ‘Armageddon?’ (1987), he contrasted his own view on the matter with that of Norman Mailer. ‘[B]ecause there is no cosmic point to the life that each of us perceives on this distant bit of dust at galaxy’s edge, all the more reason for us to maintain in proper balance what we have here. Because there is nothing else.’ Five years later, in Screening History, a meditation on the significance of cinema in his own life, Vidal suggested that the medium of film offers an alternative possibility of immortality.

Let’s face it, quantum mechanics mystifies most of us. But as Quantum Drama shows, it baffled its creators, too – so much so that some of them turned to suicide, drink, or psychiatry (Carl Jung was a favourite). Who wouldn’t go crazy, trying to get their head around such bizarre happenings as subatomic particles sometimes being wave-like, and a theory that cannot tell you the particle’s definite state – its position and velocity, say – before you measure it? In ordinary ‘classical’ physics, by contrast, you can predict in advance every point on the trajectory of an ordinary object, such as a ball or a spacecraft, launched from any given place with any particular velocity. But quantum theory does not play by these long-established rules: until you observe the particle, all the theory can tell you are the chances it will show up at various places. As Einstein asked, ‘Do you really believe the Moon is only there when you look at it?’

On 27 August 1783, Jacques Charles launched the world’s first hydrogen balloon flight from the Champ de Mars (now the site of the Eiffel Tower). He excluded his rival Jacques-Étienne Montgolfier from the ticketed reserve. Then, on 21 November, Charles and another ‘navigateur aérien’ made the first manned flight, landing thirty kilometres north of Paris. Montgolfier was invited to cut a ribbon as a gesture of reconciliation in the name of science.

In Gabriel García Márquez’s most famous novel, One Hundred Years of Solitude (1967), Colonel Aureliano Buendía twice requests that his poetry be destroyed – first when he is in prison, preparing to face the firing squad. He hands his mother a roll of sweat-stained poems and instructs her to burn them. ‘Promise me that no one will read them,’ he says. His mother promises, but does not burn the poems. Years later, as a different family member is about to light the oven, the colonel hands her the same roll of yellowed papers. ‘Light it with this,’ he says. When she refuses, the colonel feeds the poems to the fire himself.
