September Guest Speaker – Dr. Po-Shen Loh

Dr. Po-Shen Loh, National Coach of the USA Math Olympiad Team, ranked #1 in the world 2015 & 2016, was scheduled to give a presentation to the Florida Association for the Gifted before Hurricane Irma cancelled the conference. But Developing Extreme Math Talent can’t be stopped by extreme weather, and Dr. Po-Shen Loh will join the Orlando Math Circle this Saturday, September 16, to share his vision for bringing the majority of Americans to a math level currently attained only by the top 1%.

After his talk on Developing Extreme Math Talent, Po will host a special problem-solving workshop as a preview for the upcoming Who Wants to Be a Mathematician contest.

For Orlando high-school students, it’s a chance in a lifetime. To be coached by the top math coach in the United States, and then get to participate—for free- in a national contest that is designed to bring out the hidden mathematician in each of us.

Math is for everyone, and success belongs to you. Take the first step toward a bright new future today, and here for the Saturday talk and workshop.

For mathematics Professor Po-Shen Loh, math is the art of creative thinking. And teaching math wasn’t enough for this self-described math evangelist. He launched Expii, a free math education platform that gathers difficult math problems and shares techniques for solving them.



When Math And Creativity Combine: U.S. Wins Math Olympiad For Second Consecutive Year

Meet Po-Shen Loh, the professor at Carnegie Mellon University and head coach for Team USA, who paved the way for the U.S. to win the International Mathematical Olympiad for the second consecutive year. Now he’s adding more value to the world with his new product, Expii Solve


Anyone Can Be a Math Person Once They Know the Best Learning Techniques | Po-Shen Loh

Po-Shen Loh is a Hertz Foundation Fellow and Carnegie Mellon mathematics professor who thinks that history is a much harder subject than math. Do you agree? Well, your position on that might change before and after this video.

Po-Shen Loh is a Princeton-educated mathematician, Carnegie Mellon professor, the head coach of the U.S. International Math Olympiad team, and now he’s adding start-up entrepreneur to his knock-out resume. Loh has created Expii, a math and science education tool that aims to turn every smartphone into a tutor.




U.S. Team Wins First Place at International Math Olympiad

Americans are generally lousy at math, right? At least that’s what we hear every time there is an international test and the United States doesn’t come in close to the top.





Carnegie Mellon University placed first in the Mathematical Association of America’s 77th William Lowell Putnam Competition, the premier mathematics competition for undergraduate students in North America.


September Guest Speaker – Dr. Yu

Mathematics is a language to describe physics laws at the most fundamental level – the laws of numbers. Great scientific advancement often demands that physicists and mathematicians work hand in hand

  • Dr. Weiping Yu is a scientist and a physicist at NASA Kennedy Space Center. Yu holds a doctorate in Engineering Physics and is a pioneer researcher in theoretical and applied physics, and the founder of the Universal Particle (Uon) Theory of Everything.
  • A contributing member of the American Physical Society (APS), the American Institute of Aeronautics and astronautics (AIAA) and American Society of Mechanical Engineers (ASME).
  • A frequent keynote speaker at conferences, universities, and communities; a Subject Matter Expert (SME) on NASA Digital Learning Network (DLN); a creator of the NASA/KSC Physics Research Forum.

One of the ways OMC engages students in mathematics is by bringing guest speakers to discuss math-related careers and projects to the students. On March 18th, Dr. Jami Valentine, a physicist who works for the US Patent and Trademark office, gave a talk to the Meadowbrook Middle School students. Dr. Valentine earned a master’s degree at Brown University, then went to Johns Hopkins University, where she studied the spin properties of rare earth metals under Professor C.L. Chien. In 2006 Jami became the first African-American woman to earn a Ph.D. in physics from Johns Hopkins University. This also made her the first female Florida A&M University alumna to earn a Ph.D. in Physics. Dr. Valentine captivated all the students by talking about patents, trademarks and copyrights. Everyone asked interesting questions which may even lead to students seeking patents for their innovative ideas. Dr. Valentine also spoke about her journey to become a physicist and about the role of mathematics in her career, and her determination to reach her goals.

Thank you Dr. Valentine for sharing your Saturday morning with us, for inspiring and encouraging us to do our best in school so we can one day also choose an interesting and fulfilling career.


Thank you so much to professor Po-Shen Loh for taking the time out of his busy schedule to make a stop in our community! He explained interesting applications of mathematics in the real world with unique examples such as the fairness of dice rolling. Dr. Loh, you are so inspiring. We hope to have you back for another discussion soon!
