MAA MATHFEST 2015Invited Addresses (continued)MAA CHAN STANEK LECTURE FOR STUDENTSSeventy-Five Years of MAA MathematicsCompetitionsWednesday, August 5, 1:00 PM – 1:50 PMMarriott Wardman Park, Salon 2/3Joseph Gallian, University ofMinnesota DuluthIn this talk we provide facts, statistics,oddities, curiosities, videos, and triviaquestions about the mathematicscompetitions that the MAA hassponsored for 75 years.PI MU EPSILON J. SUTHERLAND FRAME LECTUREG-sharp, A-flat, and the Euclidean AlgorithmFriday, August 7, 8:00 PM – 8:50 PMMarriott Wardman Park, Salon 2/3Noam Elkies, Harvard UniversityWhy does Western music almostuniversally use the same repeatingpattern of 7+5 notes seen in thepiano’s white and black keys, and whydoes each of these notes (especiallythe black ones, like G-sharp / A-flat)get more than one name? Using apiano, the audience’s voices, and moretraditional lecture materials, I’ll outline how music, physics, andmathematics converged to produce this structure, including anoverlap between one thread of music history and the first fewsteps of the Euclidean algorithm applied to the logarithms of 2and 3.NAM DAVID HAROLD BLACKWELL LECTUREMathematics, Mathematicians, MathematicsEducation and Equity: Challenges andOpportunitiesFriday, August 7, 1:00 PM – 1:50 PMMarriott Wardman Park, Salon 2/3Terrence Blackman, The Universityof DenverAfrican Americans have a longand honorable tradition of doingMathematics and MathematicsEducation in the African Americancommunity. In this talk, from aperspective of excellence and equity,I will address the critical necessity ofengagement in Mathematics Education, by all mathematiciansand in particular, African American mathematicians. In sodoing, I will describe some of the challenges and opportunitiesfor undergraduates considering careers in the mathematicalsciences.14 Washington, DC | August 5–8, 2015 #MAAthFest
