Jeanne Villepreux-Power began her adult life as a dressmaker, but rose to become one of the preeminent marine biologists of her day.

If you've ever been captivated by colorful fish and sea creatures darting around an aquarium, you can thank 19th century French scientist Jeanne Villepreux-Power! Villepreux-Power began her adult life as a dressmaker, but rose to become one of the preeminent marine biologists of her day. Her invention of a glass box for holding and observing marine specimens — the first recognizable glass aquarium — earned her the title "Mother of Aquariophily" from British biologist Richard Owen. "[She] was not content with purely descriptive studies of dead specimens," French scientist Claude Arnal wrote in a tribute to her. "She was excited by life and its mysteries."

Experts offer tips for parents on building girls' confidence in math.

“Why do smart people enjoy saying that they are bad at math?” laments Petra Bonfert-Taylor, a professor of engineering at Dartmouth College. “Few people would consider proudly announcing that they are bad at writing or reading.” After seeing one too many examples of adults “passing on [mathematical anxiety] like a virus,” Bonfert-Taylor has an important message for math-phobic parents and educators: “We are passing on from generation to generation the phobia for mathematics... [and] as a result, too many of us have lost the ability to examine a real-world problem, translate it into numbers, solve the problem and interpret the solution.” Continue reading → Continue reading

A Mighty Girl's top picks of math toys and games for curious Mighty Girls from toddlers to teens.

Math is all around us! From making a purchase to doubling a recipe to estimating how much longer a trip will take, we use math every day. Yet for many people there's a pervasive myth that you're either "good at math" or "bad at math" — that it's a talent you're born with, not a skill you can grow and develop with practice. And this misperception often has a significant effect on girls, who are prone to believing that their math ability is innate and that girls are less gifted at math than boys.

The Apollo 11 moon landing nearly ended in failure -- until Margaret Hamilton's flight software saved the day.

In this iconic photograph, pioneering computer scientist Margaret Hamilton stands next to the computer code that she and her team wrote to guide the Apollo spacecraft to the moon! Hamilton was the lead software designer for NASA’s Apollo program, and her forward thinking saved the 1969 Apollo 11 mission when the flight software she designed prevented a last-minute abort of the famous landing which brought the first humans to the Moon. Over the course of her career, Hamilton developed the concepts of asynchronous software, priority scheduling, and Human-in-the-loop decision capability, which became the foundation of modern software design. She also fought for programming to be given the respect it deserved, coining the term "software engineering" ; after all, as her work showed, software could make the difference between failure and a groundbreaking success.

Dr. Frances Kelsey resisted intense industry pressure to approve thalidomide; the drug was the cause of severe birth defects in over 10,000 infants in other countries.

When pharmacologist Dr. Frances Oldham Kelsey started working at the U.S. Food and Drug Administration (FDA) in 1960, one of the first files to cross her desk was an approval request for thalidomide. The drug had already been prescribed widely in Europe and other countries as a treatment for morning sickness in pregnant women, but Kelsey wasn't convinced it was safe. Her refusal to approve the drug, despite intense pressure from its manufacturer, likely saved tens of thousands of babies in America from devastating birth defects. "Representatives for the company thought I was crazy because it was such a popular drug in Europe, and they were losing money by my pigheadedness," asserted Kelsey in a later interview. "I held my ground. I just wouldn't approve it." Continue reading → Continue reading

Pioneering neuroscientist Brenda Milner, one of the founders of cognitive neuroscience, says that at 105, she's "still nosy."

If you go to the Department of Neurology and Neurosurgery at McGill University in Montreal, Canada, you might catch a glimpse of 105-year-old Dr. Brenda Milner — a pioneering neuroscientist who's still breaking new ground in her 70-year long career as a brain researcher! The eminent British-born scientist revolutionized brain science as a newly minted PhD in the 1950s. Today, she is best known for discovering where memory formation occurs in the brain and is widely recognized as one of the founders of cognitive neuroscience. Her research to better understand the inner workings of the human brain continues today, although she says that people often think she must be emerita because of her advanced age. "Well, not at all," she asserts. "I’m still nosy, you know, curious.” Continue reading → Continue reading

Dr. Kazue Togasaki became one of the first Japanese American women to earn a medical degree in the US.

In the midst of World War II, as many people of Japanese ancestry were incarcerated in internment camps, a pioneering doctor helped ensure that pregnant women got the best care she could provide. Dr. Kazue Togasaki fought sexism and racism to become one of the first Japanese American women to earn a medical degree in the US. Over the course of her remarkable career, she delivered over 10,000 babies, including 50 during one month at the Tanforan Assembly Center. "In other camps, I know they’d send the pregnant women out to the nearest county hospital to deliver, but I never thought about sending them out from Tanforan," she recalled years later. "I thought it was my duty." Continue reading → Continue reading

"Nobody, but nobody, is going to stop breathing on me."

You've likely heard doctors or parents talking about a baby's Apgar Score, but did you know that this lifesaving measure is named for its creator, Dr. Virginia Apgar, the pioneering anesthesiologist whose work has helped save countless newborns? The Apgar Score, which is now used in many countries around the world, helps doctors quickly assess the health of newborns to determine if they need medical intervention. Apgar also authored a groundbreaking book called Is My Baby All Right? which provided parents with a reassuring and informative guide to birth defects, which had previously been a taboo topic and a source of shame to many families. Apgar's unflagging determination to provide the best possible care for both women and their babies is perhaps best summed up by her famous quote: "Nobody, but nobody, is going to stop breathing on me."

Dr. Helen Taussig envisioned and helped develop a life-saving operation for the nearly always fatal "blue baby syndrome," saving the lives of tens of thousands of babies.

Dr. Helen Taussig overcame severe dyslexia, partial deafness, and sexism to earn a medical degree and, in the 1940s, she helped develop a life-saving operation for "blue baby syndrome," a birth defect of the heart that had a very high morality rate. Now recognized as the founder of the field of pediatric cardiology, her unique insights on previously incurable babies would go on to change the field of neonatal medicine forever. "To be a leader, you have to recognize where the gaps are," observed Dr. Anne Murphy, a pediatric cardiologist at Johns Hopkins Children's Center. "[Dr. Taussig] recognized there was a gap in caring for these patients with heart defects... and she made the effort to work with others to make a difference."

A Mighty Girl's top picks of picture books starring math-loving girls!

Kids are natural mathematicians: they count, they categorize, they figure out patterns and they explore shapes and geometry. Even though many people think of math as simply numbers and equations, the truth is that math is everywhere in the world and in everything we do, from pouring a drink to building a block tower to saving allowance money for a special treat! And when we share stories with our kids that celebrate both the practicalities and the wonders of math, we can give them a strong foundation for becoming life-long math lovers — a trait that will suit them well whatever their future holds.
