Summer has brought the Tangente Awards season around again. This year, three prizes will be awarded: the Tangente Book Prize and its high-school counterpart, the Tangente High School Students' Prize, as well as the Best Article Prize, awarded in partnership with the APMEP, the CultureMath website and the SMF.
Vote for your favorite book ---------------------------
Since May 25, online readers have been able to support their favorite by voting from a selection of books on mathematics published between January 1st 2020 and June 30, 2021. Haven't read them all? Don't panic: the reviews, freely available on the magazine's website, will give you a taste—and may send you racing to your favorite bookstore. Voting remains open until September 30.
In the second round, the five books with the most votes are put before a jury, which selects the winner.
The ten shortlisted books are presented below. The number in parentheses is the issue of Tangente in which the review appeared. The voting page, rules and full details can be found at www.tropheestangente.com/PT2021.php.

Your article in Tangente ------------------------
Do you enjoy writing, explaining and sharing ideas? Then the Best Article Prize is for you. Entrants submit an accessible article about mathematics in the style of Tangente. The subject is up to you, and the magazine's various sections—"knowledge," "current knowledge," "history," "action" and "connections"—offer plenty of ways to approach it. In practical terms, the article must be no longer than four pages (around 13,500 characters) and should make for smooth reading, with any slightly technical material presented in boxes. The winning article will be published in Tangente.
In 2020, the Best Article Prize went to Frédéric André for his article Homo academicus dans son labyrinthe, published in issue 198 of Tangente. An honorable mention went to Aurélie Alexandre; you can read her piece in the article *Algorithme d'Euclide et cætera*.

Several winners of this prize later became regular contributors to Tangente: Fabien Aoustin (2014), Christian Laforest (2015), Léo Gerville-Réache (2016), Antoine Rolland (2019). Details on how to enter can be found at **www.tropheestangente.com/PMA.php**.
The deadline for submitting articles is September 30, 2021.
More high school students than ever! ------------------------------------
The newest of the awards, the Tangente High School Students' Prize, continues to grow in stature. Despite the difficult conditions schools have faced over the past two years, participation has continued to rise steadily. The prize began in 2016 with some 150 students from ten high schools; during the 2020–2021 school year, more than 400 students from nearly thirty schools, some of them abroad, embarked on the adventure (see Tangente Éducation 57, 2021). As usual, the school calendar meant that the classes selected the winner in June. This year's choice was Combien de pas jusqu’à la Lune ? by Carole Trébor (Albin Michel, 2019), a fictionalized biography of Katherine Johnson (1918–2020). Honorable mentions went to Ada, a novel by Antoine Bello (Gallimard, 2016), and to the graphic novel Intelligences artificielles by Héloïse Chochois, Arnold Zéphir and FibreTigre (Delcourt, 2019).
All the prizes will be presented at the Tangente Awards ceremony, to be held this coming December.
