GREAT WOMAN OF MATHEMATICS: DR. ANGIE TURNER KING, 1905-2004. Dr. King is best known as the teacher and mentor of Katherine Johnson, the mathematician who calculated trajectories for Apollo space missions (link below) but her story is amazing in its own right. She was the 1/7 Image
granddaughter of former slaves. She lost her parents when she was very young, and was then raised for a time by her grandmother and later, separately, by her grandfather. With the trauma of slavery in her background, King's grandmother was not able to be a loving presence 2/7
for her. Her grandfather did better, insisting on getting an education for her despise his own illiteracy. She was a brilliant student, graduating high school at age 14. She went on to college, graduating cum laude from West Virginia State with degrees in mathematics and 3/7
chemistry, and earned a master's from Cornell by studying in summers and teaching during the school years. She returned to WVS to teach, including teaching chemistry to soldiers as part of the US Army Specialized Training Program, and earned her PhD in 1955 from University 4/7
of Pittsburgh. Seeing the need for both role models and devoted teachers who would invest themselves in students' success--and loving her role as a teacher and mentor most of all--she published little, devoting herself to her students. In surveys of former WVS students, 5/7
she alone garnered over a third of their votes for favorite teacher. Katherine Johnson is her most well-known former student and mentoree, but she was also very important in the life of Margaret Collins, the entomologist and civil rights advocate. In addition to a career that 6/7
made an enormous difference in many lives, Dr. King was a devoted wife and mother, raising five daughters. She lived on the WVS campus until her death in 2004. 7/7

Today's #dailymaths CHALLENGE PROBLEM. Problems are taken from the Mathematics 2021 calendar. Each day's problem is posted at 1am Eastern/6am London. Previous day's solution is added a few hours later. Guest mathematician posts welcome; DM if interested!
Yesterday's problem with solution by me, and link to extended explanation in the next tweet!
Here is a fabulous explanation of modular arithmetic by @drrollergator -- easily accessible by middle schoolers, even though most people only learn it in number theory at university. Spend your Sunday learning something amazing!

GREAT WOMAN OF MATHEMATICS: DR. WINIFRED EDGERTON MERRILL, 1862-1951. The first American woman to earn a PhD in mathematics. She was born in Wisconsin. Little is known about her parents, but they were able to provide her with both emotional and material support for her dreams 1/9
and ambitions, giving her both private tutors and a small home observatory. She earned a bachelor's degree in mathematics from Wellesley College. Pursuing a lifelong love of astronomy, she independently used data from Harvard's observatory to calculate the orbit of the 2/x
Pons-Brooks Comet, from the Halley's family of comets. This achievement bolstered her effort to be admitted to Columbia University, which at first rejected her due to her sex. She argued that their telescope and facilities provided a unique opportunity for her to further her 3/x

Yesterday's problem with a special series of answers! The answer is as simple as checking a list of the ten problems Hilbert revealed on August 8, and seeing that the Riemann is #8. But what about those problems? Why are they so special, and what do they mean? Keep reading!
Two professors, one retired and one current, wrote plain-English explanations of some of the Hilbert problems for us. Here is the first, problem #1, explained by @JohnsonFido.

GREAT WOMAN OF MATHEMATICS: Katherine Johnson, 1918-2020. Brilliant mathematician who graduated high school at age 14 despite the obstacle of no local public school being available for Black students. Took every available maths course at West Virginia State, an HBCU, which 1/6 Image
added new courses for her. Was mentored by W.W.S. Claytor, the third Black American to earn a PhD in mathematics. Graduated at age 18 with degrees in both mathematics and French. Personally integrated West Virginia University after a ruling by the Supreme Court. Took time off 2/6 Image
to raise her kids. After the early loss of her first husband, was a single mother until re-marriage at age 41. Started at NASA in 1958 where she was one of the many women involved in the space program, a remarkable achievement in a pre-feminist era that was also still very 3/6

GREAT WOMAN OF MATHEMATICS: DR. FERN HUNT, born 1948. Dr. Hunt is a probability theorist and mathematical biologist who has made important contributions to our understanding of dynamical systems and mathematical modeling. She was born in 1948 to working class parents, #GWOM 1/8 Image
who supported and encouraged her scientific and mathematical passions. With their encouragement, she became the first member of her family to graduate college. She earned AB, MS, and PhD degrees in mathematics, and worked in academia until 1993, when she left to work 2/8
in the computing and applied mathematics laboratory of the National Institute of Standards and Technology. Her work in dynamical systems relates to the mathematical modeling of genetic variation, patterns in bacteria, and nonlinear dynamics. The Monte Carlo method (pic) 3/8 Image

GREAT WOMAN OF MATHEMATICS: MARY GOLDA ROSS, 1908-2008. Mary Golda Ross was the first Native American woman to become an engineer. The great-granddaughter of a Cherokee Chief, she grew up in the Cherokee tradition, which educated boys and girls equally. She graduated from 1/x
Northeastern State Teacher's College, which was formerly the Cherokee Female Seminary, with a degree in mathematics at age 20. She spent 9 years teaching in rural Oklahoma schools during the Great Depression, taking courses towards her master's degree during summers. She went 2/x
to work for the Bureau of Indian Affairs as a statistician, then to California to seek work with Lockheed in support of US efforts during WW2. She did mathematical work on pressure effects for fighter planes, including the P-38 Lightning, then the fastest military plane ever. 3/x
