For Maths fans, 2025 is a square. 45² = 45 x 45 = 2025 Also, 9² x 5² = 2025 40² + 20² + 5² = 2025 My favourite? 1³+2³+3³+4³+5³+6³+7³+8³+9³ = 2025 #Mathematics #teaching #education

Mathematician Sofya Kovalevskaya was the first woman to: + Earn a doctorate in #mathematics (in the modern sense) + Be appointed to a full professorship in mathematics She was also one of the first women to work for a scientific journal as an editor. She died #OTD in 1891. #WomenInSTEM

Vintage black-and-white photograph of Sofya Vasilyevna Kovalevskaya (1850–1891), renowned Russian mathematician and the first major woman in modern mathematics. The young woman looks straight ahead with a thoughtful, composed gaze. She wears a formal dark Victorian blouse with a tall, stiff collar, and wide dark ribbon accents across the chest. Her hair is short dark, thick, and neatly styled.

Remembering Dr. Maryam Mirzakhani on #WorldCancerDay. Dr. Mirzakhani was first woman to win the Fields Medal, the most prestigious award in #mathematics. She died in 2017 from #breastcancer at the age of 40. stanford.io/2C0io2A #WomenInSTEM

A vibrant, composite portrait of the brilliant Iranian mathematician Maryam Mirzakhani (1977–2017), the first woman and first Iranian to win the Fields Medal. She is shown in a close-up head-and-shoulders view, facing the camera with a gentle, thoughtful expression—short brown hair, bright blue eyes, and a calm smile. She wears a navy blue fleece over a teal/green collared shirt. Overlaid transparently behind and around her is a dense blackboard filled with intricate handwritten mathematical equations in white chalk, featuring complex expressions involving binomial coefficients (e.g., n! / (k!(n-k)!)), factorials, summations, powers, and terms suggestive of hypergeometric series or combinatorial identities. The equations partially surround and frame her face, symbolizing her deep immersion in advanced mathematics, particularly in hyperbolic geometry, Teichmüller theory, and dynamical systems, while evoking the creative, exploratory nature of her work as a Stanford professor and groundbreaking researcher.

My latest cartoon for @newscientist.com #science #mathematics

Caption
"A scientist undertaking high-risk calculations in the Hazardous Mathematics Laboratory"

Image
A scientist wears an armoured hazmat suit. His face is intense and sweat drips from his brow. His hands are encased in heavy duty gloves which reach into a metal box. He peers into the box through heavy-duty perspex at a notebook in which he is making complex calculations with a biro.

Mathematician Karen Uhlenbeck is one of the founders of modern geometric analysis. #OTD in 2019, she became the first woman to win the Abel Prize, the "Nobel Prize of Math." She donated half the prize money to orgs promoting more engagement of women in research #mathematics. #WomenInSTEM #WHM

A warm, natural-light outdoor portrait of Karen Keskulla Uhlenbeck (born August 24, 1942), the groundbreaking American mathematician and the first woman to win the Abel Prize (2019) for her foundational contributions to geometric analysis, gauge theory, and partial differential equations. Captured in her later years, she stands confidently with arms crossed in a relaxed yet assertive pose under a concrete architectural overhang on a university campus (likely the University of Texas at Austin, where she is Professor Emerita and holds the Sid W. Richardson Foundation Regents Chair). Uhlenbeck has shoulder-length silver-white hair, wire-rimmed glasses, and a gentle, knowing smile that conveys warmth, intelligence, and quiet authority. She wears a long charcoal-gray cardigan over a dark top with an intricate geometric pattern (echoing her work in mathematical geometry), paired with dark pants, standing on a paved walkway with autumnal trees and a modern brutalist building in the blurred background. The soft daylight highlights her approachable yet formidable presence as a trailblazing figure in mathematics—renowned for proving regularity theorems in minimal surfaces, advancing nonlinear analysis, and inspiring generations of women in STEM through her mentorship and advocacy.

Emmy Noether was described by Albert Einstein (& others) as the most important woman in the history of #mathematics. + Many important contributions to abstract algebra + Proved Noether's first & second theorems, which are fundamental in mathematical physics Born #OTD in 1882. #WomenInSTEM #WHM

Black-and-white photograph of German mathematician Emmy Noether standing in front of a large chalkboard completely covered in dense handwritten mathematical equations, integrals, matrices, graphs, and symbols. She wears a light striped blouse with puffed sleeves and a high collar, a large dark bow tie, a wide belt with an ornate buckle, and a skirt. Her dark hair is styled in an updo as she looks to the side with a calm, neutral expression, her right hand resting on the back of an ornate wooden chair.

Tablet with calculation and addition of the areas of five fields clay 3200-2900 BCE proto Sumerian culture Jemdet Nasr, Ancient Mesopotamia present day Iraq #handmade #ancient #ancientculture #ancientwriting #cuneiform #tablet #clay #mesopotamia #sumerianculture #jemdetnasr #iraq #mathematics #art

Ancient Sumerian cuneiform tablets represent one of humanity's earliest writing systems. Developed in Mesopotamia (modern-day Iraq) around 3200 BCE, they began as administrative pictographs on clay before evolving into abstract, wedge-shaped phonetic symbols.
Early tablets like this one were used for administrative purposes to record the storage and distribution of goods, animals and people.
This tablet comes from Jemdet Nasr, the remains of an ancient site in southern Mesopotamia (modern Iraq).
Tablets such as this list quantities of different commodities using an early form of the cuneiform script, and the circles and half circles that you can see across the document indicate numerals.
This tablet is known as the 'field of the EN. It contains calculations for the areas of five fields. The scribe added these figures together and divided the grand total into thirds.
Two thirds were allocated to a person called the EN, which is Sumerian for 'lord', while the remaining third was divided unevenly among other individuals, including the wife of the EN. It clearly reflects a hierarchical society, with EN as a leading figure.

Evelyn Boyd Granville's work was instrumental during the early years of the US space program. 2nd Black woman in the US to earn a PhD in #mathematics (Yale 1949), she worked on orbit computations/computer procedures for 3 space projects: Vanguard, Mercury & Apollo.🚀 Born #OTD in 1924. #WomenInSTEM

A sepia-toned historical portrait of Evelyn Boyd Granville (1924–2023), the second Black woman to earn a Ph.D. in mathematics in the U.S. She is positioned in the center, shown from the chest up in a three-quarter pose. Her expression is calm, intelligent, and determined, with a slight, confident smile. Her dark hair is styled in a voluminous, textured updo typical of the mid-20th century. She wears a light-colored, structured blouse with a classic pointed collar. The foreground portrait is superimposed over a blurred background of a dark chalkboard filled with complex mathematical formulas, symbols, and notations—including limits, Greek letters, and geometric equations. The composition places Granville as the literal face of the advanced science behind her, symbolizing her groundbreaking work for NASA’s Project Mercury and the Apollo program. The overall mood is academic, reverent, and inspiring, highlighting her historical significance as a "Hidden Figure" who helped pave the way for women of color in STEM.
