Math Olympians

Sunday, August 15th, 2010

CIMG0897Eight young American women kicked butt in the 2010 China Girls Mathematical Olympiad held August 9 – 13 in Shijiazhuang, about 100 miles from Beijing. They brought home to the USA five gold medals, one silver medal, one bronze medal, and one honorable mention. Four of the girls are from California, three from right here in Silicon Valley. One of the gold medalists, Lynnelle Ye, proudly represents El Camino Real; she just graduated from Palo Alto High School, she’s been taking advanced math courses at Stanford University since her junior year, and she’ll be attending The Farm in the Fall.

The China Girls Mathematical Olympiad is an international event where young women attempt to solve six math problems in nine hours split over two days. No calculus is required but the problems are…challenging. Here are a couple samples I found from a similar competition.

  1. Prove that for each positive integer n, there are pairwise relatively prime integers k0, k1, …, kn, all strictly greater than 1, such that k0k1kn – 1 is the product of two consecutive integers.
  2. At a certain mathematical conference, every pair of mathematicians are either friends or strangers. At mealtime, every participant eats in one of two large dining rooms. Each mathematician insists upon eating in a room which contains an even number of his or her friends. Prove that the number of ways that the mathematicians may be split between the two rooms is a power of two (i.e., is of the form 2k for some positive integer k).

Ironically as you see the competitors are given the answers; they have to provide the proofs. It’s  the mathematical equivalent of essay  questions.

Palo Alto’s Lynnelle Ye as it turns out is a bit of a superstar, having placed fourth in the Intel Science Talent Search and second in the Siemens Competition in Math, Science & Technology. Don’t let their math prowess mislead you. From the blog postings they put up on the Mathematical Sciences Research Institute page, it’s clear they are well-balanced, bright teenagers who made the most of the extraordinary adventure they had touring China. Some excerpts:

“I’m the romantic fluffy type who wants to talk about the scenery, because Hong Kong is the coolest place on Earth. So cool that I even bought a few refrigerator magnets. I think I’m going to build my castle here when I grow up.”

“Yesterday, we went to Ocean Park for most of the day. It was awesome! We got to see a lot of animals, including giant pandas, red pandas, sea otters, chinese alligators/crocodiles, dolphins, and sea lions. My favorites were by far the giant pandas. They were so cute! (I wish that I could hug them 🙂 ).”

“So, today’s classes were lots of fun. First we had Polynomials with Po-Ru, where I got to brush up on interpolation. Then we did awesomely awesome constructions problems with Ian. Finally, in the afternoon, Carlos showed us some really cool angle-chasing problems. In fact, one of them is now my new favorite math problem!”

Congratulations to these exceptional young ladies! They’ve got math skillz, and they’ll go far.

Patricia Loomis
When I met Bill Wulf at the Rose, White, and Blue Parade on the Fourth of July, we got to talking about other local historians like Clyde Arbuckle and Ralph Rambo, both of whom he personally knew. He told me I needed to check out the work of Patricia Loomis. I was familiar with her name but had never seen any of her books. I looked her up in the San Jose Library catalog and saw that they had copies but they could not be checked out because they were signed by the author and had to stay in the King Library’s California Room.

Not long after, I was refreshing my Google bookshelf and remembered to add Pat’s books to the list. On a lark I Googled her to see what else I could find out about her and was sadly shaken to find she had passed away only a week prior. On a bittersweet note, just a few weeks before that she had celebrated her 90th birthday with a big party at San Jose Historic Park. Here’s a timeline that shows how these events all converged inside the span of 30 days.

  • 6/30/2010 — Pat celebrates her 90th Birthday at San Jose History Park
  • 7/4/2010 — Bill Wulf tells me to check out Pat’s books
  • 7/4/2010 — Paulette and I watch fireworks at San Jose History Park
  • 7/20/2010 — Pat passes away in Arroyo Grande, her hometown
  • 7/27/2010 — A memorial service is held at the South County Historical Society Heritage  House
  • 7/29/2010 — I learn all this when I randomly Google her

Pat was born in San Francisco in 1920 and grew up in Arroyo Grande near Pismo Beach. She came to San Jose to attend San Jose State University and stayed for over 60 years. She took a job at the Mercury News as a reporter but most famously between 1971 and 1981 she wrote a weekly column called “Signposts” in which she presented the history of the streets of Santa Clara County and the pioneers they were named after. That’s right, a history of the streets. This is why Bill Wulf turned me on to her. Select columns were published in two volumes called Signposts and Signposts II by the San Jose Historical Museum, the same group that runs History Park.

Last week I was up in Menlo Park and discovered a wonderfully funky used bookstore on El Camino called Feldman’s Books. I went inside and made a bee’s line to the California history section to see if maybe, just maybe they had one of Pat’s books. Eureka!

CIMG1362Signposts II is a delightful book. The table of contents reads like a South Bay atlas: Bascom Avenue, Lawrence Expessway, Montague Expressway, and more. The very first article, Abel Road in Milpitas, mentions Oakland Road and Main Street which pass by Henry Abel’s old cow pasture. I had been wondering about  Abel since it has superceded Main Street in the modern era, and now I know all about it. I learned that Henry Abel’s granddaughter Mrs. John Donovan developed Serra Shopping Center in Milpitas, a kitschy tribute to Padre Junípero. Each page is deeply researched, vibrantly narrated, and illustrated with vintage photographs. I’ll treasure it.

She wrote another seminal history book called Milpitas: a Century of Little Cornfields, 1852-1952. It’s featured in the Milpitas Historical Society’s permanent display at the Great Mall.

Pat stayed active. After retiring to Arroyo Grande she wrote two more books: Streets of Arroyo Grande and Arroyo Grande Cemetery, which incidentally is located on El Camino Real down there. Clearly she was a girl after my own heart.
