This book offers a multifaceted perspective on mathematics by demonstrating 99 different proofs of the same theorem.
Each chapter solves an otherwise unremarkable equation in distinct historical, formal, and imaginative styles that range from medieval, topological, and doggerel to chromatic, electrostatic, and psychedelic.
With a rare blend of humor and scholarly aplomb, Philip Ording weaves these variations into an accessible and wide-ranging narrative on the nature and practice of mathematics, according to a review on the Princeton University Press website.
Inspired by the experiments of the Paris-based writing group known as the Oulipo — whose members included Raymond Queneau, Italo Calvino, and Marcel Duchamp — Ording explores new ways to examine the aesthetic possibilities of mathematical activity.
99 Variations on a Proof is a mathematical take on Queneau’s Exercises in Style, a collection of 99 retellings of the same story, and it draws unexpected connections to everything from mysticism and technology to architecture and sign language.
Art Cairo spotlights pioneering artist Inji Efflatoun

CAIRO: Art Cairo 2026 returned to Egypt’s bustling capital from Jan. 23-26, with visitors treated to gallery offerings from across the Middle East as well as a solo museum exhibition dedicated to pioneering Egyptian artist Inji Efflatoun.
While gallery booths hailed from across the Arab world, guests also had the chance to explore the oeuvre of the politically charged artist, who died in 1989.
Many of the pieces in the 14-work exhibition were drawn from the collection of the Egyptian Museum of Modern Art and cover four main periods of the artist’s work, including her Harvest, Motherhood, Prison and Knoll series.

Efflatoun was a pivotal figure in modern Egyptian art and is as well known for her work as her Marxist and feminist activism.
“This is the third year there is this collaboration between Art Cairo and the Ministry of Culture,” Noor Al-Askar, director of Art Cairo, told Arab News.
“This year we said Inji because (she) has a lot of work.”
Born in 1924 to an affluent, Ottoman-descended family in Cairo, Efflatoun rebelled against her background and took part heavily in communist organizations, with her artwork reflecting her abhorrence of social inequalities and her anti-colonial sentiments.

One untitled work on show is a barbed statement on social inequalities and motherhood, featuring a shrouded mother crouched low on the ground, working as she hugs and seemingly protects two infants between her legs.
The artist was a member of the influential Art et Liberte movement, a group of staunchly anti-imperialist artists and thinkers.
In 1959, Efflatoun was imprisoned under Gamal Abdel Nasser, the second president of Egypt. The artist served her sentence for four years across a number of women’s prisons in the deserts near Cairo — it was a period that heavily impacted her art, leading to her post-release “White Light” period, marked dynamic compositions and vibrant tones.
Grouped together, four of the exhibited works take inspiration from her time in prison, with powerful images of women stacked above each other in cell bunkbeds, with feminine bare legs at sharp odds with their surroundings.

The bars of the prison cells obstruct the onlooker’s view, with harsh vertical bars juxtaposed against the monochrome stripes of the prison garb in some of her works on show.
“Modern art, Egyptian modern art, most people, they really don’t know it very well,” Al-Askar said, adding that there has been a recent uptick in interest across the Middle East, in the wake of a book on the artist by UAE art patron Sultan Sooud Al-Qassemi.
“So, without any reason, all the lights are now on Inji,” Al-Askar added.
Although it was not all-encompassing, Art Cairo’s spotlight on Efflatoun served as a powerful starting point for guests wishing to explore her artistic journey.
