Astronaut, neurologist, and photographer Dr. Roberta Bondar was #Canada's first female astronaut (1992). #WorldSpaceWeek 🚀 The world's first neurologist in space, she is globally recognized for her contributions to space medicine. #WomenInSTEM robertabondar.com
A formal portrait of Dr. Roberta Lynn Bondar from her 1992 NASA Space Shuttle Discovery mission (STS-42). Dr. Bondar, a board-certified neurologist and payload specialist, is centered in the frame from the waist up, smiling warmly with an approachable, confident expression. Her short, dark brown hair is styled in a soft crop. She wears a vibrant orange NASA Launch and Entry spacesuit featuring a black neck ring, a prominent circular mission patch on her right chest, and a rectangular name tag with a gold astronaut symbol on her left chest. Her hands rest gently on a dark surface in the foreground next to her matching white flight helmet, which features a large, glossy black visor. Framed closely behind her are two flags: the American Stars and Stripes on the left and the Canadian Maple Leaf on the right, symbolizing the international scientific partnership. The composition is balanced and official, radiating a proud, triumphant, and historic mood that commemorates breaking barriers for women in STEM.A candid shot of Dr. Roberta Bondar in her post-spaceflight career as an accomplished fine-art nature photographer and global environmental researcher. Viewed in profile from the waist up, Dr. Bondar is positioned on the right side of the frame inside the covered canopy of an outdoor field vehicle. She looks intently through the viewfinder of a high-end, professional Hasselblad medium-format camera mounted to a sturdy, articulated tripod arm. She wears a comfortable, light gray hooded zip-up sweatshirt with a dark patterned scarf around her neck and reading glasses hanging loosely over her chest. Her expression is focused, thoughtful, and serene. The background opens to a vast, flat shoreline and a calm body of water under a pale blue sky, showcasing the remote natural environments she documents. The natural, soft daytime lighting emphasizes an analytical yet deeply passionate mood, visually connecting her scientific background in observation to her enduring artistic dedication to Earth's ecosystems.

#OTD in 1893, New Zealand became the first self-governing country in the world to grant all adult women the right to vote in national parliamentary elections. The first election held after this milestone was in November 1893--an incredible 82% of registered female voters voted. #WomensSuffrage
This image shows a bronze bas-relief detail from the Kate Sheppard National Memorial located on Oxford Terrace in Christchurch, New Zealand. A tribute to New Zealand's women's suffrage movement, depicting prominent campaigners. From left to right, the main figures featured in the sculpture are Meri Te Tai Mangakāhia, Amey Daldy, Kate Sheppard (center next to a wheelbarrow of suffrage petitions), Ada Wells, Harriet Morison, and Helen Nicol. The monument honors the landmark 1893 Electoral Act, signed on 19 September 1893, which made New Zealand the first self-governing country in the world where women won the right to vote in parliamentary elections.

#CivilRights activist Claudette Colvin was born #OTD in 1939. On March 2, 1955, she was arrested for refusing to give up her seat on a bus in segregated Montgomery, AL. She was 1 of 4 plaintiffs in Browder v. Gayle that led to the ruling that Alabama bus segregation laws were unconstitutional.
A black-and-white historical composite image honors civil rights pioneer Claudette Colvin (born September 5, 1939). On the right is a head-and-shoulder portrait of Colvin as a 15-year-old girl. She faces forward with a calm, resilient expression and a slight, dignified smile. She wears thick, dark-rimmed cat-eye glasses, and her short, textured hair is styled in neat waves. Her dark sweater contrasts softly against the plain, light background. On the left side of the composition are archival clippings from a 1955 newspaper article reporting on her arrest. Bold headlines read "Girl, 15, Guilty In Bus Seat Case" and "Negro Girl Found Guilty Of Segregation Violation," detailing her conviction in juvenile court for refusing to give up her seat on a segregated Montgomery, Alabama bus. The stark juxtaposition of her bright, youthful face against the harsh segregationist headlines creates a poignant, solemn mood, underscoring her monumental bravery as a key catalyst for the Montgomery bus boycott.

Joan Clarke: the lone female cryptanalyst in Alan Turing’s inner circle. A math genius denied her Cambridge degree for being a woman, she mastered "Banburismus" to crack Nazi U-boat Enigma keys, saving thousands of Allied lives in the Battle of the Atlantic. Died #OTD in 1996. #WomenInSTEM #WWII
A studio portrait of British cryptanalyst and codebreaker Joan Clarke (1917–1996), celebrated for her elite mathematical role in Alan Turing's inner circle at Bletchley Park during World War II. The overall composition captures Clarke from the chest up in a left-facing side profile, with her head turned toward the viewer. She looks directly at the camera with a calm, intelligent, and subtly smiling expression. She has short, darkly styled curly hair arranged in voluminous waves. She wears round, thin-framed wire glasses, dark lipstick, and a formal military or institutional uniform jacket featuring lapels, buttons, a collared shirt, and a dark necktie beneath. Stitched onto her upper sleeve is an insignia consisting of a white spread-winged bird patch above two parallel chevron stripes. The setting is a minimalist studio background with a neutral, soft gradient gray tone. The clear lighting emphasizes the historic, dignified, and determined mood of a pioneering wartime mathematician.

A close-up color photograph of Iranian mathematician Maryam Mirzakhani (1977–2017), the groundbreaking Fields Medal winner and Stanford professor renowned as the first woman and first Iranian to receive mathematics' highest honor in 2014. Captured during the International Congress of Mathematicians (ICM) at the COEX convention center in Seoul, South Korea (August 2014), she is seated at a press conference or panel, resting her chin thoughtfully on her left hand with her elbow propped up, conveying deep concentration and quiet introspection. Mirzakhani has short dark brown hair, expressive blue-green eyes gazing slightly upward and to the side, and a subtle, contemplative expression with lightly furrowed brows and a gentle half-smile. She wears a dark blue or navy top and wears an earpiece and thin boom mic. The vibrant turquoise-blue background displays large white lettering reading "COEX Sec" (part of "COEX Seoul" or similar event branding), softly blurred behind her, with a faint shadow of her figure adding depth. This intimate portrait captures Mirzakhani's characteristic humility, intellectual intensity, and grace amid the historic moment of her Fields Medal recognition, symbolizing her profound contributions to the geometry and dynamics of Riemann surfaces and moduli spaces.

Why is Anthropic destroying books? | Kathryn James
The AI company apparently found destructively scanning ‘all the books in the world’ easier than dealing with copyright in its quest for training data

A charming black-and-white photograph of computer science pioneer Frances E. Allen (1932–2020). She is looking slightly off-camera to the right with a vibrant, joyful smile that wrinkles the corners of her eyes behind her rimless eyeglasses. She has short, wavy, light-colored hair styled in a soft crop. She wears a dark, high-necked turtleneck top or sweater and a delicate, dark drop earrings. A hint of a metallic chain necklace is visible. The soft-focus background is muted and non-distinct, emphasizing her warm expression. The lighting gently illuminates her face, highlighting her cheerful, approachable mood. Frances Allen is historically significant as a pioneer in optimizing compilers, the first female IBM Fellow, and the first woman to win the ACM Turing Award.

Crop yields down, our countryside scorched and over 2800 people are dead due to this summer's heatwaves. Meanwhile fossil fuel giants are raking in record profits. We must end this rampant profiteering, and cut fossil fuels from our energy mix as soon as possible.

As I often do on a Sunday, I worshipped at Sunderland Minster, part of the Inclusive Church network, yesterday. A verse from one song read: "But we make his love too narrow by false limits of our own; and we magnify his strictness with a zeal he will not own." ... 1/2

The Arctic Circle just reached a temperature that once seemed almost impossible for such a frozen region: above 100°F, or 38°C … a shocking first … fragile regions are rapidly changing. Sometimes one number can tell a much bigger story … climate change is no longer distant. It’s here. It’s now.
