Her Story "Charm Quark"

I wish I could take credit for all the information below but Lorajean from Knitted Wit did all the research for us. Come in and see Charm Quark in all it's "quarkiness". Read below about this fascinating woman who happens to also be a "Badger".

Meet Sau Lan Wu, a scientist who's been making a mark in her field since her graduate student days at UW Madison. The discoveries in particle physics that she has made make our knitterly brains feel a bit… scrambled. They all have the sweetest names (Charm Quark, Gluon, Higgs Boson) with super important, understanding-the-world-we-live-in significance. We're making our best effort to distill the information we've been researching into a snappy little letter, but a big grain of salt to all of you actual scientists out there: PLEASE forgive us our lack of actual scientific knowledge surrounding this stuff. To misquote Dr. McCoy from Star Trek: "Dammit, people! We're fiber artists, not scientists!" Sau Lan Wu was born in Hong Kong, the daughter of a businessman who she rarely saw and his sixth concubine (what?!?!). Her youth was informed by her absentee father, her mother's poverty, and the Japanese occupation of Hong Kong… She recalls her mother shielding her and her brother from the bombing raids and living in a corridor of a rice shop in a Hong Kong slum. Her greatest dream was of being financially independent of men, and fortunately she had a mother that believed in the importance of education for her daughter. This was the 1940s and 50s, when, for the most part, the education of women was neither considered necessary nor important. Wu once dreamed of becoming a painter, but after reading a biography of our January HerStory subject, Marie Curie, she decided to devote herself to the study of physics. After high school, she received a full scholarship to Vassar College, and traveled alone (by boat!) from Hong Kong to get to New York. While there, along with the shock of living on a prestigious college campus in America (she likened it to feeling like a princess), she also experienced both the best (a visit to the White House and an audience with Jackie Kennedy!!) and the worst (a visit to the Supreme Court where she was faced with the choice of entering a "whites" or a "colored" restroom) of America. In 1963, she went on to study for both an MA and a PhD at Harvard, where she faced some hardcore sexism (including getting kicked out of a congratulatory luncheon for graduates at Harvard Yard, among many other overt and covert instances of harassment), and is currently an Enrico Fermi Professor of Physics at the University of Wisconsin. Her decision not to have children was a direct result of the sexism HerStory Sock Club February 2018 inherent in that time. She and her husband had long talks about starting a family, and ultimately realized that her career would be over the moment she announced a pregnancy. Sad but true. There are seventeen elementary, building-block-y particles predicted by the Standard Model, which is the ruling theory of physics. Wu was instrumental in discovering three of them, including the Higgs Boson in 2012, commonly known as the "God particle." Physicists believe that the Higgs is the particle that gives mass to matter. Without it, nothing that we know would exist, including ourselves. Mind-bending, isn't it? In 1974, she was on the Nobel-prize-winning team that led to the discovery of the Charm Quark. We googled "charm quarks for dummies" and got a kid's science website that proved to be super helpful in our understanding of these elementary particles. Quarks are the basic building blocks for protons and neutrons. They are teensy things, and the six types (up, down, charm, strange, top, and bottom) are called "flavors." Yum. In 1979, Wu was the leading figure in the discovery of the Gluon. Gluons are a type of Boson, and are known as the force-carrier between Quarks. One of the best things we read in our research is that a bunch of gluons bound together is called a glueball. After all of this research into Sau Lan Wu and particle physics, we were extra-inspired to create a colorway that reflected our favorite of her discoveries: the Charm Quark. Like the three primary colors of light, Quarks can be red, green, and blue, and when mixed, they create white light. All of this, plus a bunch of other micro-microscopic movement and quarkiness (get it? quirkiness???) is happening inside every proton and neutron out there. Which is what we think we achieved on this skein. We do want to remind everyone that true red is a son-of-a-gun, dye-wise, and sometimes, even with the extra rinsing we perform on a colorway like Charm Quark, some skeins may have a bit of extra red. If your red does spread a bit, let's get physics-cal with it and think about those quark pairs and how sometimes, they stretch themselves to the very limits, without breaking. But sometimes, they break. If yours break a bit, it's just physics, baby.
